ok, I can adjust the settings foryum, firefox and clamav, but how do you adjust ping?
is there some system.config file?

Yum, firefox and clamav use tcp, whereas ping uses icmp. You cannot proxy icmp.

so 'ping' will never work outside of my local lan when behind a proxy?

found this about ping, it was a nice way to see if the network was working.

Using Ping
http://www.southwest.com.au/~jfuller/netmeeting/netmeet.htm
Ping is a DOS utility that sends a signal to a computer on a network and waits for a reply. You can 'Ping' an Internet site using its name, or its IP Address.

The typical Ping command is: C:\PING southwest.com.au

the reply would look something like:

Pinging southwest.com.au [203.16.9.10] with 32 bytes of data
Reply from 203.16.9.10: bytes = 32 time = 141ms TTL = 63
Reply from 203.16.9.10: bytes = 32 time = 132ms TTL = 63
Reply from 203.16.9.10: bytes = 32 time = 167ms TTL = 63
Reply from 203.16.9.10: bytes = 32 time = 140ms TTL = 63

You could also Ping SWIS using: C:\PING 203.16.9.10

You can NOT Ping a system on the Internet from one of the machines behind your Proxy Server. Similarly, the machines behind your Proxy Server can not be Pinged from the wider Internet. In effect, there is no direct connection from behind your Proxy Server to any other system on the Internet.
