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.
A simple way to find out is to use the IP address instead of host name.
No, because the server may do reverse (and forward) lookup in both cases. These ones are often the cause of slow connections, etc. sshd_config: UseDNS no and maybe also on client: ssh_config: CheckHostIP no cu, Rudi -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
