Re: [MLUG] RTNETLINK answers: Network is unreachable

An easy test - connect it to just a simple network switch, i.e. 4 port device, see if you can start up the connection.  You won't be able to ping anything, but you'll be able to at least see if you're on the network.  After that, I'd look at your kernel.

Right now, it's basically unable to assign an IP address to your interface, implying either a bad connection to the switch or an internal error with the driver or similar.

Ah, debugging questions.  I can deal with them.

Yes, I've checked the cables.

The server is on a VLAN in the MU system.  Might there be a problem

beyond my port?

Thanks,

James.

Are you static or dynamic for your IP?  What does your /etc/ 

resolv.conf look like?  Double checked that your cable is good?

I needed to move my production server, Ronald, (running Red Hat 9

nicely rearranged and ready for the return of the computers.

After issuing the "halt" command Ronald, issued a few protest about  

it's

inability to umount /usr2 due to a file being too large.  But  

otherwise

it went down nicely (I think).

I've restarted the box and everything appears to be running nicely -

except that it can't get to nor be seen by the internet (nor campus

network for that matter).

A "/sbin/ifup eth0" produces the responses:

RTNETLINK answers: Network is unreachable

RTNETLINK answers: Invalid argument

I've been "visited" by my boss and received comments from users  

that the

server is down.  Their comments haven't been helpful, hopefully MLUG

members will be more constructive.

Please!
