2021-09-13	space_server: bond all 3 gigabit ports, and enjoy 3x1G uplink3x1g-bond	Asbjørn Sloth Tønnesen
	Before: - enp1s0: wan - enp2s0: lan (with VLANs) - enp3s0: mgt Changes in this patch: - wan is moved to VLAN id 5 - bond0 is created, replacing lan as lower device for VLANs - mgt config is removed (could be reconfigured as a VLAN, and made a available on a switch port) - all 3 ports are enslaved in bond0 From the switch towards the space server load-balance algorithm src-dst-ip* is used. From the space server towards the switch L3+L4 is used. Therefore a single IP pair will always use the same 1G from the swith to the space server, a client therefore needs to multiplex over multiple IPs in order to *) The src-dst-ip algorithm on the switch hasn't been tested with IPv6 yet. Hopefully we can find a better switch at some point, so we can include the L4 ports in the hashing on the switch. Signed-off-by: Asbjørn Sloth Tønnesen <asbjorn@labitat.dk>
2021-09-06	space_server: add dedicated VLAN for Tor exit nodesnew-tor-exit-range	Asbjørn Sloth Tønnesen
	Move the Tor exit nodes to their own VLAN, and their own address space. Background for move ------------------- For the first Tor exit node, we where able to create inet6num object 2a01:4262:1ab:20::71/128. So we could assign a specific Tor abuse contact. When we added the second node it was no longer possible to create /128 inet6num objects, but only up to /64. We therefore need to move our Tor exit nodes to a dedicated address space. Connection tracking ------------------- Connection tracking is quite expensive, so it's better to only do it for Tor traffic, when we actually need it, which is only when internal clients need to access the servers. In the future conntrack could also be disabled for labicolo in general.

Also reading /proc/net/nf_conntrack is quite slow atm.: [root@space ~]# time cat /proc/net/nf_conntrack > /dev/null real 0m35.097s user 0m0.010s sys 0m28.114s Signed-off-by: Asbjørn Sloth Tønnesen <asbjorn@labitat.dk>
