Allowing WSUS through Squid
Trying to install WSUS on a server 2003 machine which connects to the internet via a debian linux webserver running squid as a proxy server.
When I go to open the WSUS console I get "The requested URL could not be retrieved, unable to determine the ip address for host name computername.
Generated by squid/2.5 stable9

Anyone any Ideas of how to let the program access the internet to retreive the updates.
The updates will then be exported to a further WSUS server on a network not connected to the internet.

Many thanks

Can your squid proxy machine correctly resolve DNS names of Microsoft's windows update servers?

The WSUS window opens as a Internet explorer page with the address as http://computername/wsusadmin
This is the local pc.

The linux server uses dns settings as provided by BT, and how can I check if the sever can resolve names to microsoft updates, sorry bit of a dummy.
Is it trying to resolve to microsoft?
Windows updates work fine on XP pcs

Log onto the linux server, open a console and type


If this works, it should come back and say something like:


~ $ nslookup
Address:  xxx.xx.xx.xx

Non-authoritative answer:

If it doesn't work, check that the DNS servers are being set correctly in Linux by checking the contents of /etc/resolv.conf.

The nslookup code came back just as you said, I presume that means the the DNS through the server is ok.

It does. Now try exactly the same command on your WSUS box to see if that works.

I have tried the same code on my windows server2003 box in a command prompt window and get back
No Default server available
server: Uknown
Unknown Can't find no response from server.
