Title: Local Machines do not resolve
Post by: Tim Jones on September 12, 2003, 04:10:58 AM

Hi Folks,

Under SME 5.6U4, we have added local systems to our server via the server-manager.  The entries all look correct - i.e.:

    anvil.tolisgroup.com    Local    Local    192.168.1.6

I've also checked /home/dns/db.tolisgroup.com and the entry exists:

    anvil    IN  A 192.168.1.6

However, neither the SME server nor any client can resolve the anvil machine.  Any attempt to 'dig' anvil results in:

bash-2.05a# dig anvil

; <<>> DiG 8.3 <<>> anvil

This is incorrect as the SME named had (for some reason) sent the resquest through to the root server for resolution.  We do have a forwarder setup in the named.conf file that points to our ISP's name server.

nsswitch is set to files dns
the resolve.conf is the default created by the templates

Can someone provide pointers as to what further troubleshooting can be done to resolve (pun intended) this issue?  It's tough to operate when we have to remember the IP addresses (or manually install /etc/hosts files).

That's almost always the wrong thing to do. So much so that in latest development versions of the console we've removed that dialog.  Let the SME server resolve all names.

Hi Charlie,

That did it.  I removed the upstream resolver and voila!

Thanks,

Tim

(of course, while we'll probably never know - why did it work under 5.1.2 with a forwarder defined?)
