##################################
#/proc/sys/net/ipv4/* Variables:
##################################
net.ipv4.ip_forward = 0
#	0 - disabled (default)
#	not 0 - enabled
#
#	Forward Packets between interfaces.
#
#	This variable is special, its change resets all configuration
#	parameters to their default state (RFC1122 for hosts, RFC1812
#	for routers)
#
net.ipv4.ip_default_ttl = 64
#	Default value of TTL field (Time To Live) for outgoing (but not
#	forwarded) IP packets. Should be between 1 and 255 inclusive.
#	Default: 64 (as recommended by RFC1700)
#
net.ipv4.ip_no_pmtu_disc = 0
#	Disable Path MTU Discovery. If enabled in mode 1 and a
#	fragmentation-required ICMP is received, the PMTU to this
#	destination will be set to min_pmtu (see below). You will need
#	to raise min_pmtu to the smallest interface MTU on your system
#	manually if you want to avoid locally generated fragments.
#
#	In mode 2 incoming Path MTU Discovery messages will be
#	discarded. Outgoing frames are handled the same as in mode 1,
#	implicitly setting IP_PMTUDISC_DONT on every created socket.
#
#	Mode 3 is a hardend pmtu discover mode. The kernel will only
#	accept fragmentation-needed errors if the underlying protocol
#	can verify them besides a plain socket lookup. Current
#	protocols for which pmtu events will be honored are TCP, SCTP
#	and DCCP as they verify e.g. the sequence number or the
#	association. This mode should not be enabled globally but is
#	only intended to secure e.g. name servers in namespaces where
#	TCP path mtu must still work but path MTU information of other
#	protocols should be discarded. If enabled globally this mode
#	could break other protocols.
#
#	Possible values: 0-3
#	Default: FALSE
#
net.ipv4.min_pmtu = 552
#	default 552 - minimum discovered Path MTU
#
net.ipv4.ip_forward_use_pmtu = 0
#	By default we don't trust protocol path MTUs while forwarding
#	because they could be easily forged and can lead to unwanted
#	fragmentation by the router.
#	You only need to enable this if you have user-space software
#	which tries to discover path mtus by itself and depends on the
#	kernel honoring this information. This is normally not the
#	case.
#	Default: 0 (disabled)
#	Possible values:
#	0 - disabled
#	1 - enabled
#
net.ipv4.fwmark_reflect = 0
#	Controls the fwmark of kernel-generated IPv4 reply packets that are not
#	associated with a socket for example, TCP RSTs or ICMP echo replies).
#	If unset, these packets have a fwmark of zero. If set, they have the
#	fwmark of the packet they are replying to.
#	Default: 0
#
net.ipv4.route.max_size = 
#	Maximum number of routes allowed in the kernel. Increase
#	this when using large numbers of interfaces and/or routes.
#	From Linux kernel >=3.6 onwards, this is deprecated for ipv4
#	as route cache is no longer used!
#
net.ipv4.neigh.default.gc_thresh1 = 128
#	Minimum number of entries to keep.  Garbage collector will not
#	purge entries if there are fewer than this number.
#	Default: 128
#
net.ipv4.neigh.default.gc_thresh2 = 512
#	Threshold when garbage collector becomes more aggressive about
#	purging entries. Entries older than 5 seconds will be cleared
#	when over this number.
#	Default: 512
#
net.ipv4.neigh.default.gc_thresh3 = 1024
#	Maximum number of neighbor entries allowed.  Increase this
#	when using large numbers of interfaces and when communicating
#	with large numbers of directly-connected peers.
#	Default: 1024
#
net.ipv4.neigh.default.unres_qlen_bytes = 65536
#	The maximum number of bytes which may be used by packets
#	queued for each	unresolved address by other network layers.
#	(added in linux 3.3)
#	Setting negative value is meaningless and will return error.
#	Default: 65536 Bytes(64KB)
#
net.ipv4.neigh.default.unres_qlen = 31
#	The maximum number of packets which may be queued for each
#	unresolved address by other network layers.
#	(deprecated in linux 3.3) : use unres_qlen_bytes instead.
#	Prior to linux 3.3, the default value is 3 which may cause
#	unexpected packet loss. The current default value is calculated
#	according to default value of unres_qlen_bytes and true size of
#	packet.
#	Default: 31
#
net.ipv4.mtu_expires =
#	Time, in seconds, that cached PMTU information is kept.
#
net.ipv4.min_adv_mss =
#	The advertised MSS depends on the first hop route MTU, but will
#	never be lower than this setting.
#
####IP Fragmentation:
#
net.ipv4.ipfrag_high_thresh =
#	Maximum memory used to reassemble IP fragments. When
#	ipfrag_high_thresh bytes of memory is allocated for this purpose,
#	the fragment handler will toss packets until ipfrag_low_thresh
#	is reached. This also serves as a maximum limit to namespaces
#	different from the initial one.
#
net.ipv4.ipfrag_low_thresh = 
#	Maximum memory used to reassemble IP fragments before the kernel
#	begins to remove incomplete fragment queues to free up resources.
#	The kernel still accepts new fragments for defragmentation.
#
net.ipv4.ipfrag_time = 
#	Time in seconds to keep an IP fragment in memory.
#
net.ipv4.ipfrag_max_dist = 64
#	ipfrag_max_dist is a non-negative integer value which defines the
#	maximum "disorder" which is allowed among fragments which share a
#	common IP source address. Note that reordering of packets is
#	not unusual, but if a large number of fragments arrive from a source
#	IP address while a particular fragment queue remains incomplete, it
#	probably indicates that one or more fragments belonging to that queue
#	have been lost. When ipfrag_max_dist is positive, an additional check
#	is done on fragments before they are added to a reassembly queue - if
#	ipfrag_max_dist (or more) fragments have arrived from a particular IP
#	address between additions to any IP fragment queue using that source
#	address, it's presumed that one or more fragments in the queue are
#	lost. The existing fragment queue will be dropped, and a new one
#	started. An ipfrag_max_dist value of zero disables this check.
#
#	Using a very small value, e.g. 1 or 2, for ipfrag_max_dist can
#	result in unnecessarily dropping fragment queues when normal
#	reordering of packets occurs, which could lead to poor application
#	performance. Using a very large value, e.g. 50000, increases the
#	likelihood of incorrectly reassembling IP fragments that originate
#	from different IP datagrams, which could result in data corruption.
#	Default: 64
#
####INET peer storage:
#
net.ipv4.net.ipv4.inet_peer_threshold = 
#	The approximate size of the storage.  Starting from this threshold
#	entries will be thrown aggressively.  This threshold also determines
#	entries' time-to-live and time intervals between garbage collection
#	passes.  More entries, less time-to-live, less GC interval.
#
net.ipv4.inet_peer_minttl =
#	Minimum time-to-live of entries.  Should be enough to cover fragment
#	time-to-live on the reassembling side.  This minimum time-to-live  is
#	guaranteed if the pool size is less than inet_peer_threshold.
#	Measured in seconds.
#
net.ipv4.inet_peer_maxttl =
#	Maximum time-to-live of entries.  Unused entries will expire after
#	this period of time if there is no memory pressure on the pool (i.e.
#	when the number of entries in the pool is very small).
#	Measured in seconds.
#
####TCP variables:
#
net.ipv4.somaxconn = 128
#	Limit of socket listen() backlog, known in userspace as SOMAXCONN.
#	Defaults to 128.  See also tcp_max_syn_backlog for additional tuning
#	for TCP sockets.
#
net.ipv4.tcp_abort_on_overflow = 
#	If listening service is too slow to accept new connections,
#	reset them. Default state is FALSE. It means that if overflow
#	occurred due to a burst, connection will recover. Enable this
#	option _only_ if you are really sure that listening daemon
#	cannot be tuned to accept connections faster. Enabling this
#	option can harm clients of your server.
#
net.ipv4.tcp_adv_win_scale = 1
#	Count buffering overhead as bytes/2^tcp_adv_win_scale
#	(if tcp_adv_win_scale > 0) or bytes-bytes/2^(-tcp_adv_win_scale),
#	if it is <= 0.
#	Possible values are [-31, 31], inclusive.
#	Default: 1
#
net.ipv4.tcp_allowed_congestion_control = 
#	Show/set the congestion control choices available to non-privileged
#	processes. The list is a subset of those listed in
#	tcp_available_congestion_control.
#	Default is "reno" and the default setting (tcp_congestion_control).
#
net.ipv4.tcp_app_win = 31
#	Reserve max(window/2^tcp_app_win, mss) of window for application
#	buffer. Value 0 is special, it means that nothing is reserved.
#	Default: 31
#
net.ipv4.tcp_autocorking = 1
#	Enable TCP auto corking :
#	When applications do consecutive small write()/sendmsg() system calls,
#	we try to coalesce these small writes as much as possible, to lower
#	total amount of sent packets. This is done if at least one prior
#	packet for the flow is waiting in Qdisc queues or device transmit
#	queue. Applications can still use TCP_CORK for optimal behavior
#	when they know how/when to uncork their sockets.
#	Default : 1
#
net.ipv4.tcp_available_congestion_control =
#	Shows the available congestion control choices that are registered.
#	More congestion control algorithms may be available as modules,
#	but not loaded.
#
net.ipv4.tcp_base_mss = 
#	The initial value of search_low to be used by the packetization layer
#	Path MTU discovery (MTU probing).  If MTU probing is enabled,
#	this is the initial MSS used by the connection.
#
tcp_congestion_control = 
#	Set the congestion control algorithm to be used for new
#	connections. The algorithm "reno" is always available, but
#	additional choices may be available based on kernel configuration.
#	Default is set as part of kernel configuration.
#	For passive connections, the listener congestion control choice
#	is inherited.
#	[see setsockopt(listenfd, SOL_TCP, TCP_CONGESTION, "name" ...) ]
#
net.ipv4.tcp_dsack = 
#	Allows TCP to send "duplicate" SACKs.
#
net.ipv4.tcp_early_retrans = 3
#	Enable Early Retransmit (ER), per RFC 5827. ER lowers the threshold
#	for triggering fast retransmit when the amount of outstanding data is
#	small and when no previously unsent data can be transmitted (such
#	that limited transmit could be used). Also controls the use of
#	Tail loss probe (TLP) that converts RTOs occurring due to tail
#	losses into fast recovery (draft-dukkipati-tcpm-tcp-loss-probe-01).
#	Possible values:
#		0 disables ER
#		1 enables ER
#		2 enables ER but delays fast recovery and fast retransmit
#		  by a fourth of RTT. This mitigates connection falsely
#		  recovers when network has a small degree of reordering
#		  (less than 3 packets).
#		3 enables delayed ER and TLP.
#		4 enables TLP only.
#	Default: 3
#
net.ipv4.tcp_ecn = 2
#	Control use of Explicit Congestion Notification (ECN) by TCP.
#	ECN is used only when both ends of the TCP connection indicate
#	support for it.  This feature is useful in avoiding losses due
#	to congestion by allowing supporting routers to signal
#	congestion before having to drop packets.
#	Possible values are:
#		0 Disable ECN.  Neither initiate nor accept ECN.
#		1 Enable ECN when requested by incoming connections and
#		  also request ECN on outgoing connection attempts.
#		2 Enable ECN when requested by incoming connections
#		  but do not request ECN on outgoing connections.
#	Default: 2
#
net.ipv4.tcp_fack = 
#	Enable FACK congestion avoidance and fast retransmission.
#	The value is not used, if tcp_sack is not enabled.
#
net.ipv4.tcp_fin_timeout = 60
#	The length of time an orphaned (no longer referenced by any
#	application) connection will remain in the FIN_WAIT_2 state
#	before it is aborted at the local end.  While a perfectly
#	valid "receive only" state for an un-orphaned connection, an
#	orphaned connection in FIN_WAIT_2 state could otherwise wait
#	forever for the remote to close its end of the connection.
#	Cf. tcp_max_orphans
#	Default: 60 seconds
#
net.ipv4.tcp_frto = 0
#	Enables Forward RTO-Recovery (F-RTO) defined in RFC5682.
#	F-RTO is an enhanced recovery algorithm for TCP retransmission
#	timeouts.  It is particularly beneficial in networks where the
#	RTT fluctuates (e.g., wireless). F-RTO is sender-side only
#	modification. It does not require any support from the peer.
#
#	By default it's enabled with a non-zero value. 0 disables F-RTO.
#
net.ipv4.tcp_invalid_ratelimit = 500
#	Limit the maximal rate for sending duplicate acknowledgments
#	in response to incoming TCP packets that are for an existing
#	connection but that are invalid due to any of these reasons:
#
#	  (a) out-of-window sequence number,
#	  (b) out-of-window acknowledgment number, or
#	  (c) PAWS (Protection Against Wrapped Sequence numbers) check failure
#
#	This can help mitigate simple "ack loop" DoS attacks, wherein
#	a buggy or malicious middlebox or man-in-the-middle can
#	rewrite TCP header fields in manner that causes each endpoint
#	to think that the other is sending invalid TCP segments, thus
#	causing each side to send an unterminating stream of duplicate
#	acknowledgments for invalid segments.
#
#	Using 0 disables rate-limiting of dupacks in response to
#	invalid segments; otherwise this value specifies the minimal
#	space between sending such dupacks, in milliseconds.
#
#	Default: 500 (milliseconds).
#
net.ipv4.tcp_keepalive_time =
#	How often TCP sends out keepalive messages when keepalive is enabled.
#	Default: 2hours.
#
net.ipv4.tcp_keepalive_probes = 9
#	How many keepalive probes TCP sends out, until it decides that the
#	connection is broken. Default value: 9.
#
net.ipv4.tcp_keepalive_intvl =
#	How frequently the probes are send out. Multiplied by
#	tcp_keepalive_probes it is time to kill not responding connection,
#	after probes started. Default value: 75sec i.e. connection
#	will be aborted after ~11 minutes of retries.
#
net.ipv4.tcp_low_latency = 0
#	If set, the TCP stack makes decisions that prefer lower
#	latency as opposed to higher throughput.  By default, this
#	option is not set meaning that higher throughput is preferred.
#	An example of an application where this default should be
#	changed would be a Beowulf compute cluster.
#	Default: 0
#
net.ipv4.tcp_max_orphans =
#	Maximal number of TCP sockets not attached to any user file handle,
#	held by system.	If this number is exceeded orphaned connections are
#	reset immediately and warning is printed. This limit exists
#	only to prevent simple DoS attacks, you _must_ not rely on this
#	or lower the limit artificially, but rather increase it
#	(probably, after increasing installed memory),
#	if network conditions require more than default value,
#	and tune network services to linger and kill such states
#	more aggressively. Let me to remind again: each orphan eats
#	up to ~64K of unswappable memory.
#
net.ipv4.tcp_max_syn_backlog = 
#	Maximal number of remembered connection requests, which have not
#	received an acknowledgment from connecting client.
#	The minimal value is 128 for low memory machines, and it will
#	increase in proportion to the memory of machine.
#	If server suffers from overload, try increasing this number.
#
net.ipv4.tcp_max_tw_buckets =
#	Maximal number of timewait sockets held by system simultaneously.
#	If this number is exceeded time-wait socket is immediately destroyed
#	and warning is printed. This limit exists only to prevent
#	simple DoS attacks, you _must_ not lower the limit artificially,
#	but rather increase it (probably, after increasing installed memory),
#	if network conditions require more than default value.
#
net.ipv4.tcp_mem =
#	min: below this number of pages TCP is not bothered about its
#	memory appetite.
#
#	pressure: when amount of memory allocated by TCP exceeds this number
#	of pages, TCP moderates its memory consumption and enters memory
#	pressure mode, which is exited when memory consumption falls
#	under "min".
#
#	max: number of pages allowed for queueing by all TCP sockets.
#
#	Defaults are calculated at boot time from amount of available
#	memory.
#
net.ipv4.tcp_memtcp_moderate_rcvbuf = 
#	If set, TCP performs receive buffer auto-tuning, attempting to
#	automatically size the buffer (no greater than tcp_rmem[2]) to
#	match the size required by the path for full throughput.  Enabled by
#	default.
#
net.ipv4.tcp_mtu_probing = 
#	Controls TCP Packetization-Layer Path MTU Discovery.  Takes three
#	values:
#	  0 - Disabled
#	  1 - Disabled by default, enabled when an ICMP black hole detected
#	  2 - Always enabled, use initial MSS of tcp_base_mss.
#
net.ipv4.tcp_no_metrics_save = 
#	By default, TCP saves various connection metrics in the route cache
#	when the connection closes, so that connections established in the
#	near future can use these to set initial conditions.  Usually, this
#	increases overall performance, but may sometimes cause performance
#	degradation.  If set, TCP will not cache metrics on closing
#	connections.
#
net.ipv4.tcp_orphan_retries = 
#	This value influences the timeout of a locally closed TCP connection,
#	when RTO retransmissions remain unacknowledged.
#	See tcp_retries2 for more details.
#
#	The default value is 8.
#	If your machine is a loaded WEB server,
#	you should think about lowering this value, such sockets
#	may consume significant resources. Cf. tcp_max_orphans.
#
net.ipv4.tcp_reordering = 3
#	Initial reordering level of packets in a TCP stream.
#	TCP stack can then dynamically adjust flow reordering level
#	between this initial value and tcp_max_reordering
#	Default: 3
#
net.ipv4.tcp_max_reordering = 300
#	Maximal reordering level of packets in a TCP stream.
#	300 is a fairly conservative value, but you might increase it
#	if paths are using per packet load balancing (like bonding rr mode)
#	Default: 300
#
tcp_retrans_collapse - BOOLEAN
#	Bug-to-bug compatibility with some broken printers.
#	On retransmit try to send bigger packets to work around bugs in
#	certain TCP stacks.
#
net.ipv4.tcp_retries1 = 
#	This value influences the time, after which TCP decides, that
#	something is wrong due to unacknowledged RTO retransmissions,
#	and reports this suspicion to the network layer.
#	See tcp_retries2 for more details.
#
#	RFC 1122 recommends at least 3 retransmissions, which is the
#	default.
#
net.ipv4.tcp_retries2 = 
#	This value influences the timeout of an alive TCP connection,
#	when RTO retransmissions remain unacknowledged.
#	Given a value of N, a hypothetical TCP connection following
#	exponential backoff with an initial RTO of TCP_RTO_MIN would
#	retransmit N times before killing the connection at the (N+1)th RTO.
#
#	The default value of 15 yields a hypothetical timeout of 924.6
#	seconds and is a lower bound for the effective timeout.
#	TCP will effectively time out at the first RTO which exceeds the
#	hypothetical timeout.
#
#	RFC 1122 recommends at least 100 seconds for the timeout,
#	which corresponds to a value of at least 8.
#
net.ipv4.tcp_rfc1337 = 0
#	If set, the TCP stack behaves conforming to RFC1337. If unset,
#	we are not conforming to RFC, but prevent TCP TIME_WAIT
#	assassination.
#	Default: 0
#
net.ipv4.tcp_rmem = 1
#	min: Minimal size of receive buffer used by TCP sockets.
#	It is guaranteed to each TCP socket, even under moderate memory
#	pressure.
#	Default: 1 page
#
#	default: initial size of receive buffer used by TCP sockets.
#	This value overrides net.core.rmem_default used by other protocols.
#	Default: 87380 bytes. This value results in window of 65535 with
#	default setting of tcp_adv_win_scale and tcp_app_win:0 and a bit
#	less for default tcp_app_win. See below about these variables.
#
#	max: maximal size of receive buffer allowed for automatically
#	selected receiver buffers for TCP socket. This value does not override
#	net.core.rmem_max.  Calling setsockopt() with SO_RCVBUF disables
#	automatic tuning of that socket's receive buffer size, in which
#	case this value is ignored.
#	Default: between 87380B and 6MB, depending on RAM size.
#
net.ipv4.tcp_sack = 
#	Enable select acknowledgments (SACKS).
#
net.ipv4.tcp_slow_start_after_idle = 1
#	If set, provide RFC2861 behavior and time out the congestion
#	window after an idle period.  An idle period is defined at
#	the current RTO.  If unset, the congestion window will not
#	be timed out after an idle period.
#	Default: 1
#
net.ipv4.tcp_stdurg = 0
#	Use the Host requirements interpretation of the TCP urgent pointer field.
#	Most hosts use the older BSD interpretation, so if you turn this on
#	Linux might not communicate correctly with them.
#	Default: FALSE
#
net.ipv4.tcp_synack_retries = 
#	Number of times SYNACKs for a passive TCP connection attempt will
#	be retransmitted. Should not be higher than 255. Default value
#	is 5, which corresponds to 31seconds till the last retransmission
#	with the current initial RTO of 1second. With this the final timeout
#	for a passive TCP connection will happen after 63seconds.
#
net.ipv4.tcp_syncookies = 1
#	Only valid when the kernel was compiled with CONFIG_SYN_COOKIES
#	Send out syncookies when the syn backlog queue of a socket
#	overflows. This is to prevent against the common 'SYN flood attack'
#	Default: 1
#
#	Note, that syncookies is fallback facility.
#	It MUST NOT be used to help highly loaded servers to stand
#	against legal connection rate. If you see SYN flood warnings
#	in your logs, but investigation	shows that they occur
#	because of overload with legal connections, you should tune
#	another parameters until this warning disappear.
#	See: tcp_max_syn_backlog, tcp_synack_retries, tcp_abort_on_overflow.
#
#	syncookies seriously violate TCP protocol, do not allow
#	to use TCP extensions, can result in serious degradation
#	of some services (f.e. SMTP relaying), visible not by you,
#	but your clients and relays, contacting you. While you see
#	SYN flood warnings in logs not being really flooded, your server
#	is seriously misconfigured.
#
#	If you want to test which effects syncookies have to your
#	network connections you can set this knob to 2 to enable
#	unconditionally generation of syncookies.
#
net.ipv4.tcp_fastopen = 1
#	Enable TCP Fast Open feature (draft-ietf-tcpm-fastopen) to send data
#	in the opening SYN packet. To use this feature, the client application
#	must use sendmsg() or sendto() with MSG_FASTOPEN flag rather than
#	connect() to perform a TCP handshake automatically.
#
#	The values (bitmap) are
#	1: Enables sending data in the opening SYN on the client w/ MSG_FASTOPEN.
#	2: Enables TCP Fast Open on the server side, i.e., allowing data in
#	   a SYN packet to be accepted and passed to the application before
#	   3-way hand shake finishes.
#	4: Send data in the opening SYN regardless of cookie availability and
#	   without a cookie option.
#	0x100: Accept SYN data w/o validating the cookie.
#	0x200: Accept data-in-SYN w/o any cookie option present.
#	0x400/0x800: Enable Fast Open on all listeners regardless of the
#	   TCP_FASTOPEN socket option. The two different flags designate two
#	   different ways of setting max_qlen without the TCP_FASTOPEN socket
#	   option.
#
#	Default: 1
#
#	Note that the client & server side Fast Open flags (1 and 2
#	respectively) must be also enabled before the rest of flags can take
#	effect.
#
#	See include/net/tcp.h and the code for more details.
#
net.ipv4.tcp_syn_retries = 
#	Number of times initial SYNs for an active TCP connection attempt
#	will be retransmitted. Should not be higher than 255. Default value
#	is 6, which corresponds to 63seconds till the last retransmission
#	with the current initial RTO of 1second. With this the final timeout
#	for an active TCP connection attempt will happen after 127seconds.
#
net.ipv4.tcp_timestamps = 
#	Enable timestamps as defined in RFC1323.
#
net.ipv4.tcp_min_tso_segs = 2
#	Minimal number of segments per TSO frame.
#	Since linux-3.12, TCP does an automatic sizing of TSO frames,
#	depending on flow rate, instead of filling 64Kbytes packets.
#	For specific usages, it's possible to force TCP to build big
#	TSO frames. Note that TCP stack might split too big TSO packets
#	if available window is too small.
#	Default: 2
#
net.ipv4.tcp_tso_win_divisor = 3
#	This allows control over what percentage of the congestion window
#	can be consumed by a single TSO frame.
#	The setting of this parameter is a choice between burstiness and
#	building larger TSO frames.
#	Default: 3
#
net.ipv4.tcp_tw_recycle = 0
#	Enable fast recycling TIME-WAIT sockets. Default value is 0.
#	It should not be changed without advice/request of technical
#	experts.
#
net.ipv4.tcp_tw_reuse = 0
#	Allow to reuse TIME-WAIT sockets for new connections when it is
#	safe from protocol viewpoint. Default value is 0.
#	It should not be changed without advice/request of technical
#	experts.
#
net.ipv4.tcp_window_scaling =
#	Enable window scaling as defined in RFC1323.
#
net.ipv4.tcp_wmem = 
#	min: Amount of memory reserved for send buffers for TCP sockets.
#	Each TCP socket has rights to use it due to fact of its birth.
#	Default: 1 page
#
#	default: initial size of send buffer used by TCP sockets.  This
#	value overrides net.core.wmem_default used by other protocols.
#	It is usually lower than net.core.wmem_default.
#	Default: 16K
#
#	max: Maximal amount of memory allowed for automatically tuned
#	send buffers for TCP sockets. This value does not override
#	net.core.wmem_max.  Calling setsockopt() with SO_SNDBUF disables
#	automatic tuning of that socket's send buffer size, in which case
#	this value is ignored.
#	Default: between 64K and 4MB, depending on RAM size.
#
net.ipv4.tcp_notsent_lowat = 
#	A TCP socket can control the amount of unsent bytes in its write queue,
#	thanks to TCP_NOTSENT_LOWAT socket option. poll()/select()/epoll()
#	reports POLLOUT events if the amount of unsent bytes is below a per
#	socket value, and if the write queue is not full. sendmsg() will
#	also not add new buffers if the limit is hit.
#
#	This global variable controls the amount of unsent data for
#	sockets not using TCP_NOTSENT_LOWAT. For these sockets, a change
#	to the global variable has immediate effect.
#
#	Default: UINT_MAX (0xFFFFFFFF)
#
net.ipv4.tcp_workaround_signed_windows = 0
#	If set, assume no receipt of a window scaling option means the
#	remote TCP is broken and treats the window as a signed quantity.
#	If unset, assume the remote TCP is not broken even if we do
#	not receive a window scaling option from them.
#	Default: 0
#
net.ipv4.tcp_thin_linear_timeouts = 0
#	Enable dynamic triggering of linear timeouts for thin streams.
#	If set, a check is performed upon retransmission by timeout to
#	determine if the stream is thin (less than 4 packets in flight).
#	As long as the stream is found to be thin, up to 6 linear
#	timeouts may be performed before exponential backoff mode is
#	initiated. This improves retransmission latency for
#	non-aggressive thin streams, often found to be time-dependent.
#	For more information on thin streams, see
#	Documentation/networking/tcp-thin.txt
#	Default: 0
#
net.ipv4.tcp_thin_dupack = 0
#	Enable dynamic triggering of retransmissions after one dupACK
#	for thin streams. If set, a check is performed upon reception
#	of a dupACK to determine if the stream is thin (less than 4
#	packets in flight). As long as the stream is found to be thin,
#	data is retransmitted on the first received dupACK. This
#	improves retransmission latency for non-aggressive thin
#	streams, often found to be time-dependent.
#	For more information on thin streams, see
#	Documentation/networking/tcp-thin.txt
#	Default: 0
#
net.ipv4.tcp_limit_output_bytes = 131072
#	Controls TCP Small Queue limit per tcp socket.
#	TCP bulk sender tends to increase packets in flight until it
#	gets losses notifications. With SNDBUF autotuning, this can
#	result in a large amount of packets queued in qdisc/device
#	on the local machine, hurting latency of other flows, for
#	typical pfifo_fast qdiscs.
#	tcp_limit_output_bytes limits the number of bytes on qdisc
#	or device to reduce artificial RTT/cwnd and reduce bufferbloat.
#	Default: 131072
#
net.ipv4.tcp_challenge_ack_limit = 100
#	Limits number of Challenge ACK sent per second, as recommended
#	in RFC 5961 (Improving TCP's Robustness to Blind In-Window Attacks)
#	Default: 100
#
####UDP variables:
#
net.ipv4.udp_mem = 
#	Number of pages allowed for queueing by all UDP sockets.
#
#	min: Below this number of pages UDP is not bothered about its
#	memory appetite. When amount of memory allocated by UDP exceeds
#	this number, UDP starts to moderate memory usage.
#
#	pressure: This value was introduced to follow format of tcp_mem.
#
#	max: Number of pages allowed for queueing by all UDP sockets.
#
#	Default is calculated at boot time from amount of available memory.
#
net.ipv4.udp_rmem_min = 
#	Minimal size of receive buffer used by UDP sockets in moderation.
#	Each UDP socket is able to use the size for receiving data, even if
#	total pages of UDP sockets exceed udp_mem pressure. The unit is byte.
#	Default: 1 page
#
net.ipv4.udp_wmem_min = 
#	Minimal size of send buffer used by UDP sockets in moderation.
#	Each UDP socket is able to use the size for sending data, even if
#	total pages of UDP sockets exceed udp_mem pressure. The unit is byte.
#	Default: 1 page
#
####CIPSOv4 Variables:
#
net.ipv4.cipso_cache_enable = 1
#	If set, enable additions to and lookups from the CIPSO label mapping
#	cache.  If unset, additions are ignored and lookups always result in a
#	miss.  However, regardless of the setting the cache is still
#	invalidated when required when means you can safely toggle this on and
#	off and the cache will always be "safe".
#	Default: 1
#
net.ipv4.cipso_cache_bucket_size = 10
#	The CIPSO label cache consists of a fixed size hash table with each
#	hash bucket containing a number of cache entries.  This variable limits
#	the number of entries in each hash bucket; the larger the value the
#	more CIPSO label mappings that can be cached.  When the number of
#	entries in a given hash bucket reaches this limit adding new entries
#	causes the oldest entry in the bucket to be removed to make room.
#	Default: 10
#
net.ipv4.cipso_rbm_optfmt = 0
#	Enable the "Optimized Tag 1 Format" as defined in section 3.4.2.6 of
#	the CIPSO draft specification (see Documentation/netlabel for details).
#	This means that when set the CIPSO tag will be padded with empty
#	categories in order to make the packet data 32-bit aligned.
#	Default: 0
#
net.ipv4.cipso_rbm_structvalid = 0
#	If set, do a very strict check of the CIPSO option when
#	ip_options_compile() is called.  If unset, relax the checks done during
#	ip_options_compile().  Either way is "safe" as errors are caught else
#	where in the CIPSO processing code but setting this to 0 (False) should
#	result in less work (i.e. it should be faster) but could cause problems
#	with other implementations that require strict checking.
#	Default: 0
#
####IP Variables:
#
net.ipv4.ip_local_port_range = 
#	Defines the local port range that is used by TCP and UDP to
#	choose the local port. The first number is the first, the
#	second the last local port number. The default values are
#	32768 and 61000 respectively.
#
net.ipv4.ip_local_reserved_ports = 
#	Specify the ports which are reserved for known third-party
#	applications. These ports will not be used by automatic port
#	assignments (e.g. when calling connect() or bind() with port
#	number 0). Explicit port allocation behavior is unchanged.
#
#	The format used for both input and output is a comma separated
#	list of ranges (e.g. "1,2-4,10-10" for ports 1, 2, 3, 4 and
#	10). Writing to the file will clear all previously reserved
#	ports and update the current list with the one given in the
#	input.
#
#	Note that ip_local_port_range and ip_local_reserved_ports
#	settings are independent and both are considered by the kernel
#	when determining which ports are available for automatic port
#	assignments.
#
#	You can reserve ports which are not in the current
#	ip_local_port_range, e.g.:
#
#	$ cat /proc/sys/net/ipv4/ip_local_port_range
#	32000	61000
#	$ cat /proc/sys/net/ipv4/ip_local_reserved_ports
#	8080,9148
#
#	although this is redundant. However such a setting is useful
#	if later the port range is changed to a value that will
#	include the reserved ports.
#
#	Default: Empty
#
net.ipv4.net.ipv4.ip_nonlocal_bind = 0
#	If set, allows processes to bind() to non-local IP addresses,
#	which can be quite useful - but may break some applications.
#	Default: 0
#
net.ipv4.ip_dynaddr = 0
#	If set non-zero, enables support for dynamic addresses.
#	If set to a non-zero value larger than 1, a kernel log
#	message will be printed when dynamic address rewriting
#	occurs.
#	Default: 0
#
net.ipv4.ip_early_demux = 1
#	Optimize input packet processing down to one demux for
#	certain kinds of local sockets.  Currently we only do this
#	for established TCP sockets.
#
#	It may add an additional cost for pure routing workloads that
#	reduces overall throughput, in such case you should disable it.
#	Default: 1
#
net.ipv4.icmp_echo_ignore_all = 0
#	If set non-zero, then the kernel will ignore all ICMP ECHO
#	requests sent to it.
#	Default: 0
#
net.ipv4.icmp_echo_ignore_broadcasts = 1
#	If set non-zero, then the kernel will ignore all ICMP ECHO and
#	TIMESTAMP requests sent to it via broadcast/multicast.
#	Default: 1
#
net.ipv4.icmp_ratelimit = 1000
#	Limit the maximal rates for sending ICMP packets whose type matches
#	icmp_ratemask (see below) to specific targets.
#	0 to disable any limiting,
#	otherwise the minimal space between responses in milliseconds.
#	Note that another sysctl, icmp_msgs_per_sec limits the number
#	of ICMP packets	sent on all targets.
#	Default: 1000
#
net.ipv4.icmp_msgs_per_sec 1000
#	Limit maximal number of ICMP packets sent per second from this host.
#	Only messages whose type matches icmp_ratemask (see below) are
#	controlled by this limit.
#	Default: 1000
#
net.ipv4.icmp_msgs_burst = 50
#	icmp_msgs_per_sec controls number of ICMP packets sent per second,
#	while icmp_msgs_burst controls the burst size of these packets.
#	Default: 50
#
net.ipv4.icmp_ratemask = 
#	Mask made of ICMP types for which rates are being limited.
#	Significant bits: IHGFEDCBA9876543210
#	Default mask:     0000001100000011000 (6168)
#
#	Bit definitions (see include/linux/icmp.h):
#		0 Echo Reply
#		3 Destination Unreachable *
#		4 Source Quench *
#		5 Redirect
#		8 Echo Request
#		B Time Exceeded *
#		C Parameter Problem *
#		D Timestamp Request
#		E Timestamp Reply
#		F Info Request
#		G Info Reply
#		H Address Mask Request
#		I Address Mask Reply
#
#	* These are rate limited by default (see default mask above)
#
net.ipv4.icmp_ignore_bogus_error_responses = 1
#	Some routers violate RFC1122 by sending bogus responses to broadcast
#	frames.  Such violations are normally logged via a kernel warning.
#	If this is set to TRUE, the kernel will not give such warnings, which
#	will avoid log file clutter.

#	If non-zero, the message will be sent with the primary address of
#	the interface that received the packet that caused the icmp error.
#	This is the behaviour network many administrators will expect from
#	a router. And it can make debugging complicated network layouts
#	much easier.
#
#	Note that if no primary address exists for the interface selected,

#
net.ipv4.igmp_max_memberships = 
#	Change the maximum number of multicast groups we can subscribe to.
#	Default: 20
#
#	Theoretical maximum value is bounded by having to send a membership

#	datagrams, or risk confusing the switch and leaving groups you don't
#	intend to).
#
#	The number of supported groups 'M' is bounded by the number of group
#	report entries you can fit into a single datagram of 65535 bytes.
#
#	M = 65536-sizeof (ip header)/(sizeof(Group record))
#
#	Group records are variable length, with a minimum of 12 bytes.
#	So net.ipv4.igmp_max_memberships should not be set higher than:
#

#
net.ipv4.medium_id = 
#	Integer value used to differentiate the devices by the medium they

#	the broadcast packets are received only on one of them.
#	The default value 0 means that the device is the only interface
#	to its medium, value of -1 means that medium is not known.
#
#	Currently, it is used to change the proxy_arp behavior:
#	the proxy_arp feature is enabled for packets forwarded between
#	two devices attached to different media.
#
net.ipv4.proxy_arp = 
#	Do proxy arp.
#	proxy_arp for the interface will be enabled if at least one of

#
net.ipv4.proxy_arp_pvlan = 
#	Private VLAN proxy arp.
#	Basically allow proxy arp replies back to the same interface
#	(from which the ARP request/solicitation was received).
#
#	This is done to support (ethernet) switch features, like RFC
#	3069, where the individual ports are NOT allowed to
#	communicate with each other, but they are allowed to talk to
#	the upstream router.  As described in RFC 3069, it is possible
#	to allow these hosts to communicate through the upstream
#	router by proxy_arp'ing. Don't need to be used together with
#	proxy_arp.
#
#	This technology is known by different names:
#	  In RFC 3069 it is called VLAN Aggregation.
#	  Cisco and Allied Telesyn call it Private VLAN.
#	  Hewlett-Packard call it Source-Port filtering or port-isolation.

#
net.ipv4.accept_local = 0

#	default FALSE
#
net.ipv4.route_localnet = 
#	Do not consider loopback addresses as martian source or destination
#	while routing. This enables the use of 127/8 for local routing purposes.
#	default FALSE
#
net.ipv4.rp_filter = 
#	0 - No source validation.
#	1 - Strict mode as defined in RFC3704 Strict Reverse Path
#	    Each incoming packet is tested against the FIB and if the interface
#	    is not the best reverse path the packet check will fail.
#	    By default failed packets are discarded.
#	2 - Loose mode as defined in RFC3704 Loose Reverse Path
#	    Each incoming packet's source address is also tested against the FIB
#	    and if the source address is not reachable via any interface
#	    the packet check will fail.
#
#	Current recommended practice in RFC3704 is to enable strict mode
#	to prevent IP spoofing from DDos attacks. If using asymmetric routing
#	or other complicated routing, then loose mode is recommended.
#
#	The max value from conf/{all,interface}/rp_filter is used
#	when doing source validation on the {interface}.
#
#	Default value is 0. Note that some distributions enable it
#	in startup scripts.
#
net.ipv4.arp_filter = 
#	1 - Allows you to have multiple network interfaces on the same
#	subnet, and have the ARPs for each interface be answered
#	based on whether or not the kernel would route a packet from
#	the ARP'd IP out that interface (therefore you must use source
#	based routing for this to work). In other words it allows control
#	of which cards (usually 1) will respond to an arp request.
#
#	0 - (default) The kernel can respond to arp requests with addresses
#	from other interfaces. This may seem wrong but it usually makes
#	sense, because it increases the chance of successful communication.
#	IP addresses are owned by the complete host on Linux, not by
#	particular interfaces. Only for more complex setups like load-
#	balancing, does this behaviour cause problems.

#
net.ipv4.arp_announce = 
#	Define different restriction levels for announcing the local
#	source IP address from IP packets in ARP requests sent on
#	interface:
#	0 - (default) Use any local address, configured on any interface
#	1 - Try to avoid local addresses that are not in the target's
#	subnet for this interface. This mode is useful when target
#	hosts reachable via this interface require the source IP
#	address in ARP requests to be part of their logical network
#	configured on the receiving interface. When we generate the
#	request we will check all our subnets that include the
#	target IP and will preserve the source address if it is from
#	such subnet. If there is no such subnet we select source
#	address according to the rules for level 2.
#	2 - Always use the best local address for this target.
#	In this mode we ignore the source address in the IP packet
#	and try to select local address that we prefer for talks with
#	the target host. Such local address is selected by looking
#	for primary IP addresses on all our subnets on the outgoing
#	interface that include the target IP address. If no suitable
#	local address is found we select the first local address
#	we have on the outgoing interface or on all other interfaces,
#	with the hope we will receive reply for our request and
#	even sometimes no matter the source IP address we announce.
#
#	The max value from conf/{all,interface}/arp_announce is used.
#
#	Increasing the restriction level gives more chance for
#	receiving answer from the resolved target while decreasing
#	the level announces more valid sender's information.
#
net.ipv4.arp_ignore = 
#	Define different modes for sending replies in response to
#	received ARP requests that resolve local target IP addresses:
#	0 - (default): reply for any local target IP address, configured
#	on any interface
#	1 - reply only if the target IP address is local address
#	configured on the incoming interface
#	2 - reply only if the target IP address is local address
#	configured on the incoming interface and both with the
#	sender's IP address are part from same subnet on this interface
#	3 - do not reply for local addresses configured with scope host,
#	only resolutions for global and link addresses are replied
#	4-7 - reserved
#	8 - do not reply for all local addresses
#
#	The max value from conf/{all,interface}/arp_ignore is used
#	when ARP request is received on the {interface}
#
net.ipv4.arp_notify = 0
#	Define mode for notification of address and device changes.
#	0 - (default): do nothing
#	1 - Generate gratuitous arp requests when device is brought up
#	    or hardware address changes.
#
net.ipv4.arp_accept = 
#	Define behavior for gratuitous ARP frames who's IP is not
#	already present in the ARP table:
#	0 - don't create new entries in the ARP table
#	1 - create new entries in the ARP table
#
#	Both replies and requests type gratuitous arp will trigger the
#	ARP table to be updated, if this setting is on.
#
#	If the ARP table already contains the IP address of the

#
#
net.ipv4.app_solicit = 0

#
net.sctp.addip_enable = 0
#	Enable or disable extension of  Dynamic Address Reconfiguration

#
#	1: Enable extension.
#
#	0: Disable extension.
#
#	Default: 0
#
net.sctp.addip_noauth_enable = 0
#	Dynamic Address Reconfiguration (ADD-IP) requires the use of
#	authentication to protect the operations of adding or removing new
#	addresses.  This requirement is mandated so that unauthorized hosts
#	would not be able to hijack associations.  However, older
#	implementations may not have implemented this requirement while
#	allowing the ADD-IP extension.  For reasons of interoperability,
#	we provide this variable to control the enforcement of the
#	authentication requirement.
#
#	1: Allow ADD-IP extension to be used without authentication.  This
#	   should only be set in a closed environment for interoperability
#	   with older implementations.
#
#	0: Enforce the authentication requirement
#
#	Default: 0

net.sctp.auth_enable = 0
#	Enable or disable Authenticated Chunks extension.  This extension

#
#	Default: 10
#
net.sctp.max_init_retransmits = 8
#	The maximum number of retransmissions of INIT and COOKIE-ECHO chunks
#	that an association will attempt before declaring the destination
#	unreachable and terminating.
#
#	Default: 8
#
net.sctp.path_max_retrans = 5
#	The maximum number of retransmissions that will be attempted on a given
#	path.  Once this threshold is exceeded, the path is considered
#	unreachable, and new traffic will use a different path when the
#	association is multihomed.
#
#	Default: 5
#
net.sctp.pf_retrans = 0
#	The number of retransmissions that will be attempted on a given path
#	before traffic is redirected to an alternate transport (should one
#	exist).  Note this is distinct from path_max_retrans, as a path that
#	passes the pf_retrans threshold can still be used.  Its only
#	deprioritized when a transmission path is selected by the stack.  This
#	setting is primarily used to enable fast failover mechanisms without
#	having to reduce path_max_retrans to a very low value.  See:
#	http://www.ietf.org/id/draft-nishida-tsvwg-sctp-failover-05.txt
#	for details.  Note also that a value of pf_retrans > path_max_retrans
#	disables this feature
#

net.sctp.cookie_hmac_alg = sha1
#	Select the hmac algorithm used when generating the cookie value sent by
#	a listening sctp socket to a connecting client in the INIT-ACK chunk.
#	Valid values are:
#	* md5
#	* sha1
#	* none
#	Ability to assign md5 or sha1 as the selected alg is predicated on the
#	configuration of those algorithms at build time (CONFIG_CRYPTO_MD5 and

#
#	Default: Dependent on configuration.  MD5 if available, else SHA1 if
#	available, else none.
#
net.sctp.rcvbuf_policy = 
#	Determines if the receive buffer is attributed to the socket or to
#	association.   SCTP supports the capability to create multiple
#	associations on a single socket.  When using this capability, it is
#	possible that a single stalled association that's buffering a lot
#	of data may block other associations from delivering their data by
#	consuming all of the receive buffer space.  To work around this,
#	the rcvbuf_policy could be set to attribute the receiver buffer space
#	to each association instead of the socket.  This prevents the described
#	blocking.
#
#	1: rcvbuf space is per association
#	0: rcvbuf space is per socket
#
#	Default: 0
#
net.sctp.sndbuf_policy = 0
#	Similar to rcvbuf_policy above, this applies to send buffer space.

#
#1) First enable sysctl from Liberty settings, if you are on Liberty
#2) Run Root Explorer
#3) Modify /data/liberty/init.d.conf to make sure that sysctl is enabled ("sysctl = 1")
#4) Go to /system/etc/, and mount it r/w
#5) Modify sysctl.conf by long pressing the sysctl.conf file and selecting "Open in Text Editor." When finished, save the file and exit
#6) Run Terminal Emulator
#7) Type "sysctl -p" or "sysctl -w" (output should confirm whether you've done step 4&5 correctly) 
#8) Check with "sysctl -a| grep vm" or "pgrep -f crond" in Terminal Emulator if all was done! ("sysctl -a" will display all the kernel settings!

#
# How to fix permission denied - try /sbin/sysctl -p
#
#


# You can verify the Linux networking kernel parms from the root user with these commands: 
# e.g. sysctl -a | grep ipv4.ip_local

#mount -o rw,remount /system

# If not works for you try -> busybox sysctl -w
