It's unusual to see EPERM on a call to connect()... The man page 
suggests that this can be caused by a local firewall rule or an SELinux 


"yum" and "wget" should be running in an unconfined domain, so SELinux 
is *probably* not the cause.  I'd take a look at the output of "iptables 
-L OUTPUT" first.  I've tried creating local firewall rules that I'd 
expect to result in EPERM, but they do not, so I'm not sure what such a 
rule looks like.
