Dear list members,
I have a rather odd problem here and I hope you have some suggestions about it,
because I almost lost hope *sigh* ....
Our group has a small Sun cluster that is quite independent of most services of
our netprovider, a research site for high energy physics. One of the services we
use, though, is the naming service. And that one is giving us a lot of headaches
recently.
Like today: All our machines can't access any web page or remote WS outside via
the machine name. I get a connection, though, if I use the IP number. Weirdly,
nslookup works fine and resolves all the names that won;t work put in ssh or
lynx or netscape or .... To make the confusion perfect, our Linux WS has no
problems at all, though it uses the same DNS.
Probably this is a problem of our Provider. But since the only infected machines
in our subnet are our Sun WS, I wonder if there is anything I could do about it.
We are not running named/in.named and as far as I can tell, the DNS is not
cached. We use NIS, and the 'hosts' line in the nsswitch.conf looks like this:
hosts: nis [NOTFOUND=return] files
I am not sure which version of the resolvlib is installed, the latest kernel
patch we are using is 105858-15 (I know, -16 is out and highly recommended, but
right now the machines are VERY busy...)
If you need more information, let me know. Thanks in advance,
Levent
