Dear All
This is slightly off topic , but you guys have helped me with routing problems
in the past, and I\'m at my wits end as to why this doesn\'t work. If I can
ever get this thing to work I\'ll have a real server for use with an existing
LVS :-(
I\'m trying to set up a new real server. It is a a dell 1650 server with two
Intel Etherexpress/1000 NICS, running RH linux 7.3. One of the NICS is
disabled.
The problem is that I cant connect to anything when the box initiates the
request. For example if I ping localhost or the server\'s own IP address I get
a reply, but anything
else, including other boxes on the same subnet and the GW just give
host unreachable.
I can connect to the box with SSH no problem and view web pages on Apache which
is running on it (tho\' as soon as the box uses a page that connects to another
server ie mail etc it fails). I can also ping the box from any other PC and
receive a reply.
Other boxes with exactly the same configuration (but different
NICs/IP) work fine.
I\'m sure the problem is with the network config, but can\'t see where the
issue lies. I\'ve included the outputs from ifconfig and netstat -rn below.
Can anyone suggest either what I can do to fix this or alternatively what can
be done to further investigate this problem? Is there a way to isolate it, ie
to confirm it\'s the NIC, driver etc.
Many thanks
Paul
