########## SETTINGS 

# On startup, lftp executes ~/.lftprc and ~/.lftp/rc. You can place aliases and 'set' commands 
# there. Some people prefer to see full protocol debug, use 'debug' to turn the debug on.

# Certain commands and settings take a time interval parameter. It has the format Nx[Nx...], where N is time amount
# (floating point) and x is time unit: d - days, h - hours, m - minutes, s - seconds. Default unit is second. E.g.
# 5h30m or 5.5h. Also the interval can be 'infinity', 'inf', 'never', 'forever' - it means infinite interval. E.g.
# 'sleep forever' or 'set dns:cache-expire never'.

# The name of a variable can be abbreviated unless it becomes ambiguous. The prefix before ':' can be omitted too. 
# You can set one variable several times for different closures, and thus you can get a particular settings for 
# particular state. The closure is to be specified after variable name separated with slash '/'.

# The closure for 'dns:', 'net:', 'ftp:', 'http:', 'hftp:' domain variables is currently just the host name as you
# specify it in the 'open' command (with some exceptions where closure is meaningless, e.g. dns:cache-size). For 
# some 'cmd:' domain variables the closure is current URL without path. For other variables it is not currently 
# used. See examples in the sample lftp.conf.

# Boolean settings can be one of (true, on, yes, 1, +) for a True value or one of (false, off, no, 0, -) for a False 
# value.

# There is also a system-wide startup file in /etc/lftp.conf. It can be in different directory, see FILES section.

# lftp has the following settable variables (you can also use 'set -a' to see all variables and their values):
# save plain text passwords in ~/.lftp/bookmarks on 'bookmark add' command. Off by default.

# when false, lftp refuses to go to background when exiting. To force it, use 'exit bg'.
set cmd:move-background yes

# The prompt. lftp recognizes the following backslash-escaped special characters that are decoded as follows:

# \v
# the version of lftp (e.g., 2.0.3)
# \w
# the current working directory at the remote site
# \W
# the base name of the current working directory at the remote site
# \nnn
# the character corresponding to the octal number nnn
# \\
# a backslash

# number. Default is 'ssh -a -x'. You can set it to 'rsh', for example.
set fish:connect-program "ssh -a -x"

# use specified shell on server side. Default is /bin/sh. On some systems, /bin/sh exits when doing cd to a

# address instead of the one returned by PASV command, port number would not be changed. Default is true. 
set ftp:fix-pasv-address yes

# if true, lftp will try to set up source ftp server in passive mode first, otherwise destination one. If first

set ftp:nop-interval 60

# sets passive ftp mode. This can be useful if you are behind a firewall or a dumb masquerading router. In passive
# mode lftp uses PASV command, not the PORT command which is used in active mode. In passive mode lftp itself makes
# the data connection to the server; in active mode the server connects to lftp for data transfer. Passive mode is

# specifies ftp proxy to use. To disable proxy set this to empty string. Note that it is an ftp proxy which uses 
# ftp protocol, not ftp over http. Default value is taken from environment variable ftp_proxy if it starts with

# ''password@proxy_password'' as password. 
#  When set to ''joined-acct'', lftp sends ''user@ftp.example.org proxy_user'' as user name to proxy. The site 
# password is sent as usual and the proxy password is expected in the following ACCT command.
# When set to ''open'', lftp first sends proxy user and proxy password and then ''OPEN ftp.example.org'' followed 
# by ''USER user''. The site password is then sent as usual.
# When set to ''user'' (default), lftp first sends proxy user and proxy password and then 
# ''user@ftp.example.org'' as user name. The site password is then sent as usual.

# allow usage of REST command before LIST command. This might be useful for large directories, but some ftp 
# servers silently ignore REST before LIST. 
set ftp:rest-list yes

# if false, lftp will not try to use REST before STOR. This can be useful for some buggy servers which corrupt 
# (fill with zeros) the file if REST followed by STOR is used.

# other ssl settings are only available if lftp was compiled with an ssl/tls library. 
set ftp:ssl-allow yes

# if true, lftp loads ssl:key-file for protected data connection too. When false, it does not, and the server can 
# match data and control connections by session ID. Default is true. 
# if true, refuse to send password in clear when server does not support SSL. Default is false.
set ftp:ssl-force yes

# if true, request ssl connection for data transfers. This is cpu-intensive but provides privacy. Default is false.
set ftp:ssl-protect-data yes

# if true, request ssl connection for data transfer between two ftp servers in FXP mode. CPSV or SSCN command will 
# be used in that case. If ssl connection fails for some reason, lftp would try unprotected FXP transfer unless 
# ftp:ssl-force is set for any of the two servers. Default is false. 
set ftp:ssl-protect-fxp yes

# if true, request ssl connection for file list transfers. Default is true.
set ftp:ssl-protect-list yes

# if true, lftp would issue CCC command after logon, thus disable ssl protection layer on control connection.
set ftp:ssl-use-ccc no

# interval between STAT commands. Default is 1 second.
set ftp:stat-interval 1

# if true, lftp will send one command at a time and wait for response. This might be useful if you are using a 
# buggy ftp server or router. When it is off, lftp sends a pack of commands and waits for responses - it speeds up 
# operation when round trip time is significant. Unfortunately it does not work with all ftp servers and some 
# routers have troubles with it, so it is on by default. 
set ftp:sync-mode yes

# Assume this timezone for time in listings returned by LIST command. This setting can be GMT offset 
# [+|-]HH[:MM[:SS]] or any valid TZ value (e.g. Europe/Moscow or MSK-3MSD,M3.5.0,M10.5.0/3). The default is GMT. Set

set ftp:use-site-utime2 yes

# when true (default), lftp uses SIZE command to determine file size.
set ftp:use-size yes

# if true, lftp sends STAT command in FXP mode transfer to know how much data has been transferred. See also 
# ftp:stat-interval. Default is true.
set ftp:use-stat yes

# when true, lftp uses STAT instead of LIST command. By default '.' is used as STAT argument. Using STAT, lftp 
# avoids creating data connection for directory listing. Some servers require special options for STAT, use 
# ftp:list-options to specify them (e.g. -la). 
set ftp:use-stat-for-list yes

# when true (default), lftp uses TELNET IAC command and follows TELNET protocol as specified in RFC959. When

# data connection spoofing which can lead to data corruption. Unfortunately, this can fail for certain ftp servers 
# with several network interfaces, when they do not set outgoing address on data socket, so it is disabled by 
# default. 
set ftp:verify-address yes

# verify that data connection has port 20 (ftp-data) on its remote end. This can possibly prevent data connection 
# spoofing by users of remote host. Unfortunately, too many windows and even unix ftp servers forget to set proper 
# port on data connection, thus this check is off by default.

set ftp:web-mode no

# specifies initial PROT setting for FTPS connections. Should be one of: C, S, E, P, or empty. Default is empty

# from environment variable http_proxy. If your ftp proxy requires authentication, specify user name and password in the URL. 
# hftp:proxy (URL)

# if set to off, lftp will send password as part of URL to the proxy. This may be required for some proxies (e.g. 
# M-soft). Default is on, and lftp will send password as part of Authorization header. 
# set hftp:use-authorization (boolean)

# if set to off, lftp will try to use 'GET' instead of 'HEAD' for hftp protocol. While this is slower, it may
