Outgoing Connectivity problems. Incoming connectivity fine


Howdy, all;

I have a number of issues, but I'll work them methodically: Only one at a time.

I have a CentOS-5.2 system in a normally headless situation. Use it mostly as a fileserver for the rest of the workgroup. After a planned shutdown and reboot yesterday (City workers gave 24hrs notice for utility work on the street & electrical), I've been having a devil of a time getting things working again.

The main function as a Samba smb server works OK. No data loss, and all the WindowsXP clients can see the network directories. Incoming ssh and vnc is nominally OK:

KNOWN GOOD:
1 smb running - OK
2 I can ssh in using PuTTY - OK
3 vnc service works -- but without GNOME, just the twm ugliness. That was a surprise.

Thinking I'd fix the GNOME issue with a yum update, I ssh'ed in, only to have timeouts finding baseurls for the repos. I went in through vnc to the pirut utility, and again, there's a problem with connectivity and timeouts.

A check using Firefox, and there's no connectivity to outside URLs. Interestingly, Lynx *is* capable of seeing the outside world, and I can read current news at cnn.com, so I know it's not from a cache. I can also ssh into my ISP-provided shell account (hooray for sonic.net!). So, *some* outgoing connectivity works, some doesn't.

CURRENT ISSUE:
yum cannot see repos
pirut cannot see repos
graphical browser cannot see external sites

If I can solve this issue, I think I'll be well on my way to working the rest of my issues.

Thanks!

-Fionn

I need to add the confirmation that all cache daemons (including squid) are turned off.
