Since installing F10 (clean install) my SSH and telnet logins to remote
machines often fail with a DNS error:
hughc@joss:~$ ssh xander
ssh: Could not resolve hostname xander: Name or service not known
hughc@joss:~$
However, the 2nd attempt a couple of seconds later succeeds. No other
Linux or Unix machines here are having this problem. There is nothing
about this in /var/log/messages, or in /var/log/secure. It doesn't
happen all the time, either. Not sure where to start looking for
something like this ...
I currently have NetworkManager turned off in init, and I'm using
/etc/init.d/network instead, just to see if that fixes the problem (it
doesn't).
NIS is on, but host lookups do not use NIS. From /etc/nsswitch.conf:
hosts: files dns
resolv.conf:
nameserver 172.25.9.81
nameserver 172.25.9.7
