Hi all,
I have a machine (lets called it machine 1) with two networks card, eth0 and eth1. Both have static IPs. Once in a while the machine refuses to give access to the Internet via Firefox (eth0 is the route to router). Other machines on the network have no problems accessing the Internet. Eventually the machine would just magically start working again, but this time it just seems to have stayed broken.
I've done some simple diagnostics and found:
a) I have another machine running Apache with a Wiki on our network - http://192.168.1.73:8084. Machine 1 is unable to connect to this Wiki. I get 'the connection has timed out'. I can ping 192.168.1.73 and it responds in the usual fashion.
b) If I try to ping www.google.com it times out with:
ping: unknown host www.google.com. I can ping google using its IP address.
c) On machine 1 I have tried traceroute on both www.google.com and its IP and I just get:
1 * * *
2 * * *
And so on until hop 30. Doing this on any other machine on the network works.
So while it seems I can ping internally in our network and outside, but when it attempts anything traceroute or URL related it does not work.
I would greatly appreciate any other things I could do to track this issue down, even if its to give more information.
Thanks.
