[oclug] Network Config Problem

[John Elliott]

Are you trying to ping by name or IP number?

Do you get a message like "destination unreachable"  ?

If it works by number and not by name you likely have a DNS problem.

If you get destination unreachable messages it is likely a firewall or 
routing problem.

If you can browse (HTTP) sites outside of the rogers domain, then it is 
likely a firewall problem.

Hope this helps..
