[ILUG] Network / DNS Problems

[Smith, Graham - Computing Technician]

Might be an issue relating to routes - check that
your routing/static-routes etc settings are as they
should be.....

Subject: [ILUG] Network / DNS Problems


I installed RH 7 onto my desktop machine without a problem.  BUT when I try
to ping an internal network address by name it fails.  I can ping it by IP
address OK though.  The installation is configured with two DNS addresses
and when I put an external web address into my browser it finds it by name.
So it appears that the DNS for external addresses is working and the
internal DNS isn't.

How can this be ?  I can ping the internal DNS so I know that it can see it,
if I do an NSlookup then I get a message that says :

	***Can't find server name for address 172.16.100.1: No response from
server
	Default Server: ns.isi.ie
	Address 192.111.39.1

Any ideas ?

Thanks,

Matt
