[SOLVED] Routes not persistent

computerman1983 · 09-01-2010, 08:39 PM

Hello,

I have a ubuntu 10.04.1 install with openvpn, so I have some routes in my /etc/networking/interface file. But for what ever reason when it boots the routes don't come up and I have to restart the networking before they come up. Once I do that all is well. Any idea's why it's doing that?

Thanks!

Routes in your interfaces file, I don't think so, unless they are default routes for each interface. You really need a script to set them up.

The routes are for which interfaces, standard ethernet or the openvpn tap/tun interface?

scheidel21, of course you can that's what the whole up thing is for in interfaces, you can use it to run any arbitrary thing you want conditioned on the interface coming up or down as the case may be.

excerpt from man interfaces

Quote:

pre-up command
Run command before bringing the interface up. If this command fails then ifup aborts, refraining from marking the
interface as configured, prints an error message, and exits with status 0. This behavior may change in the future.

up command

post-up command
Run command after bringing the interface up. If this command fails then ifup aborts, refraining from marking the inter-
face as configured (even though it has really been configured), prints an error message, and exits with status 0. This
behavior may change in the future.

down command

pre-down command
Run command before taking the interface down. If this command fails then ifdown aborts, marks the interface as decon-
figured (even though it has not really been deconfigured), and exits with status 0. This behavior may change in the
future.

post-down command
Run command after taking the interface down. If this command fails then ifdown aborts, marks the interface as deconfig-
ured, and exits with status 0. This behavior may change in the future.

I forgot all about the pre-up/down and up/down syntax for the interfaces file, I never had a need for them. That said perhaps he should make sure he is using this syntaxt and that he is using the post-up option.

Thanks guys for the help. estabroo was right on just reading the man file. I added the up and down commands in my config and they come up as they should. I though I tried that at one point but I don't think ubuntu can handle 192.168.1.1/16, instead i had to give it the full netmask. IE 192.168.1.1 255.255.255.0.

Thanks guys!
