SIOCADDRT: Network is unreachable message [message #25138]

Hi

I am getting SIOCADDRT: Network is unreachable errors when I add an IP address or restart the network from inside a VE.

I am running a centos 5 VE based on the meta data from this forum.

I have narrowed the problem down to the entry in /etc/sysconfig/network that says:

GATEWAY="192.0.2.1"

If I remove/comment that line out, all errors go away and everything works perfectly. Smile

This is because the default routes are also added using the /etc/sysconfig/network-scripts/route-venet0

The problem is that every time I restart the VE that GATEWAY line is re-added to the network file!

Can someone explain why it is being re-added, or whether there is a better way to solve this problem.

Cheers!

I think you should not configure network from inside the VE. I think everything should be managed using vzctl or the $VEID.conf file.

Hi

Yes i realise that, I have been adding IP addresses using vzctl, but if i restart the network (after adding some extra routes) from within the VE then I get these errors.

I have fixed the issue by commeting out the line in /etc/vz/dists/scripts/redhat-add_ip.sh:

#put_param $NETFILE GATEWAY ${FAKEGATEWAY}

This was what was putting the fake gateway in each time.

Now I don't get any errors. Smile
