Networking Problems

[Brad Bonkoski]

#1. Do you have another machine on the local net that you can ping?  If 
so, then you can confirm your NIC / Cable are working and network params 
are fine.
#2. Can you ping an IP address in the outside world?  This tests if your 
firewall / gateway is set up correctly
#3. If #2 is okay, can you ping a domain name from the outside world?  
This tests your DNS settings.

Also, you might want to flush our your iptables because some default 
rules will block icmp (i.e. ping)
