I have Tumbleweed running on an ARM board - seems to work very well, except ssh access over IPv4. After I type in the password, the client just hangs. Surprisingly, it works fine over IPv6. Does anyone recognise that situation? This appears to be some sort of incompatibity issue - with a somewhat backlevel ssh accessing sshd on Tumbleweed, it only works on IPv6, but hangs on IPv4. Trying the same with ssh from a Tumbleweed machine works on both IPv4 and IPv6. Not sure how to report this.
This may be a long-shot, Per, but does failed DNS have anything to do with this? I've seen v4 hangs when DNS wasn't available, there's even a phrase to turn off DNS look-ups in sshd_config.
Sometimes I've also seen issues with X or agent forwarding. In doubt I would try to disable them explicitly, (ssh -xa ...). You may also try non-interactive login for testing:
ssh -4 -xa remotehost true
Tnx Rudi - didn't do much good. I'd already tried disabling X forwarding. What I don't understand is - why should any issue _only_ affect IPv4?
