RouterOS / MikroTik router configuration export to connect to the Orange/Sosh Livebox 4 fiber ONT (IPv4 + IPv6)
# jan/13/2020 08:34:56 by RouterOS 6.46.1
#
# notes: \
# - wan to orange ont on ether1; \
# - lan to ap/switch on ether2; \
# - ipv4 + ipv6 w/ fw rules; \
# - using routeros dns cache for lan, proxying to the dns servers advertised by orange's dhcpv4 server; \
# - direct plug your computer w/ wireshark to your livebox 4 fiber ethernet port and reboot it, inspect the dhcpv4 packat in wireshark and extract the value of 'authsend'; \
# - the cos tag needs to be set to 6 to be accepted by the ont dhcpv4/v6 server (from default 0), this may not be required depending on your ont, check for the cos flag sent by your livebox 4 when sniffing its traffic

Personal server backup script, ran every Sunday in the early morning. It's 100% pipe-based, which means it never writes to disk as to buffer backup files before uploading them to S3. Useful to preserve SD card write cycles on a Raspberry Pi.
