Weird! Yum install/update and wget don't work.

I have a CentOS 5 server running as a web server. The web services are okay. Ping, ssh work fine both ways.

But when I try to wget or yum update or install, I get a timeout. The URLs are resolving properly. And there's no difference if IPtables is turned off or on.

Any ideas?

Have you tried to trace it? Is it possible it's being blocked at an external firewall or something similar?

Test a basic (outbound) tcp handshake with a couple arbitrary sites.

Code:

$ for I in www.yahoo.com www.google.com ;
 do nc -zvw 1 ${I} 80 ; done

Does that succeed or time out? (If the latter, you very well may be getting filtered.)
