Re: Progress on tailscale on NetBSD (plus $ available)

[David Brownlee <abs%absd.org@localhost>]

Been hammering the new tailscale package "in production" (which is to
say using it as a preferred transport for a selection of remote access
and deploy actions), and noticed three cases similar to the below when
running a moderate sized rsyncs across tailscale (~50M changed out
of~180M)

client_loop: ssh_packet_write_poll: Connection to 100.82.213.3 port
22: Address family not supported by protocol family
rsync: [sender] write error: Broken pipe (32)
rsync error: unexplained error (code 255) at io.c(849) [sender=3.4.1]

This is between a NetBSD-amd64 and some Ubuntu 24.04 hosts running
1.96.4. Restarting the process completed the rsync in each case.

Previous transport for this was wireguard-go with a Ubuntu 22.04 host
acting as a wireguard relay. I have had that case rarely go into a
state where all traffic would stop and even restarting wireguard-go
would not recover, so there *could* be a common cause and tailscale is
just better at handling some "bad state"
