solaris 10 DNS problems.... still.....

Post by matus » Tue, 11 Sep 2007 00:21:00


roblems with DNS on a new solaris 10x86 install.

The network is a dslmodem (192.168.0.1) feeding a linksys router/
switch (192.168.1.1)
feeding the hosts.
I am using static ip's on the other hosts, solaris 9, free bsd, suse
linux.
I have used the same hardware and the same ip's in all cases.

After the solaris 10 install, I was able to go to the sun website
and get patches,
was able to run the update manager and get patches that way, I was
able to get
to some sites, www.sage.org, but not go to some links on that site.

I setup the resolv.conf and nsswitch.conf the same on the solaris 9
and solaris 10.
The solaris 10 is just not right. ?

any ideas ??

Hi,

I don't know if this is THE problem, but it might be A problem:

192.168.1.1 (your router) is the gateway on your internal LAN, so I
think that THAT is the IP address that you should have in the
resolv.conf, not 192.168.0.1.

I think that the 192.168.0 is a private IP/subnet, so it won't be able
to get through the router to the DSL modem (routers aren't suppose to
route private IPs).

Try changing the resolv.conf to just:

domain domain.actdsltmp
nameserver 192.168.1.1

and then see what happens?

Is this DSL using PPPoE, perhaps?

[...]

It looks like DNS and routing are working fine.

Are you perhaps having MTU problems related to PPPoE? Try reducing
the interface MTU and see if the problems go away.
