ssh-tun — L3 TUN tunnel over SSH with per-source routing (+ reverse port forwards)

Brings up a TUN interface via ssh -w and routes traffic from specific VM source IPs through it using policy routing + conntrack marks. Inbound traffic to those VMs is unaffected (CONNMARK ensures only VM-initiated connections are tunnelled).

Optionally, also forwards connections arriving on the remote side (host/proto/port) back through the tunnel to a specific VM on the gateway's LAN — a DNAT+SNAT port-forward anchored at the remote end. A forward may be a single port or an inclusive port range, which is always mapped 1:1 onto the same ports on the VM.

Main problem - nvidia-settings needs nvidia GPUs to be started in X.

Workaround - fake displays for nvidia driver in xorg.conf:

nvidia-xconfig --enable-all-gpus
edit /etc/X11/xorg.conf:

...

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
H: preserves hard-links
A: preserves ACLs
