Re: Help Please: Network Down



Hi Marc.

I'm not an expert, but at least I have a routing table that
functions. :)

Seems fine to me. I wonder if 'localnet' and 'mareschal' need to be
specified with their IP addresses though. Are these two values defined
anywhere?

Here is my routing table, which is basically the same, except it has
literal IP addresses:

mauritsvanrees:~# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
default         192.168.1.1     0.0.0.0         UG    0      0        0 eth0

On my system the numbers for RX and TX packets are roughly equal so
your RX packet number should be around 500 or 600. I don't know wat RX
and TX actually mean, but these numbers probably say: "You have a network
error," which you already knew. :(

Other than that, all ifconfig output seems fine.

This part seems fine, though I would expect to see a line for outside
addresses as well. But I don't have a gateway computer myself, just an
off the shelf modem/router, so I can't really comment here.
