Linux Gateway (CentOS) Randomly Loses Internet Connection
I have been using a Debian box as my gateway at my house. It has always worked great, but I decided to switch to CentOS because I am more familiar with it. However, I have been running into a very weird issue. Every once in awhile I will lose connection to the internet on eth0 (my WAN interface). The weird part is 'ifconfig' shows that I still have my public IP, 'route -n' shows all the correct routes, and 'ps ax | grep dhcpclient' shows:
Thanks for your time.
You shoudl get back to debian :p
On a more serious note - it could be a DHCP issue, or a NIC bug. Run tcpdump on eth0 the next time you lose connectivity and see what you get. If it is a DHCP issue you might see requests going out and no replies. You can also try restarting the modem during the failure to see if it will reset it.
Are you using the same physical box with CentOS installed instead of Debian or a different PC?
