a crazy connectivity issue. unable to ping anything

["Michael Habashy" <mjh2000@gmail.com>]

Hi -i got a crazy connectivity issue on my hands.

THis machine was running fine for about a month or so --then i lost connectivity.

I have no errors to tell me what is going on.

i have switched the built-in nic on the motherboard and the hub ports --there are other devices that working fine.

I have disabled a lot of services..and trying to get bear vinalla as possible.

I can not ping to any other host..then just my local interface.

THe last things done were to install courier-imap and courier-ssl.

i was sending an email  to the box..and bam..there is notthing there..

 

the interfaces initialize just fine..but do not talk to anythhign...i have apache and other apps running..and their ports are open..just not talking to anyone outside the box...and yes..there is no iptables or ipchains..

I am running out of options..and do not want to rebuild box...so help!!!!!!

here are the ifconfig and netstat:
