RedHat 9.0 - Making 'route' changes permanent

Hi,

I am running RH9.0 and am trying to find a way to:

1. Undo earlier changes to the routing table such that they survive
reboots (i.e. I added some entries I now wish to delete, but they keep
coming back no matter what I change)

2. Makes permanent changes to the routing table (using 'route') so
that they survive reboots - because I have found a working
configuration I want to make permanent

I've seen much discussion on this, involving for example, changing the
'static-routes' file, but this file doesn't exist on RH9.0! The file
/proc/net/route seems to contain information I might want to change,
but it refuses to allow changes, even as 'root'.

I'm confused; any help appreciated. It seems that the nature of this
problem changes from version to version. Many HOWTOS etc. list
commands that don't work and talk about files that don't exist...

Thanks,

Chris

I don't know much about how the redhat distro does its system
initialization scripts, never cared for it myself so I switched to
slackware.

Are you running a dhcp client, pppoe client or something else like that
that would change your routing?

Provided there's no such process that is actively overwriting your routing,
then it's just a matter of determing the precise sequence of route commands
you need, e.g.

route add ..
route add default gw
....

Then insert these into whatever script your system runs during boot.
Routing is contained within the kernel so it will be uninitialized until
you run those route commands.

The static-routes file is indeed gone. You now put your permanent
routing information into /etc/sysconfig/network-scripts/route-eth(x).
I think that redhat-config-network will do that for you also but I
have not tried it.

Yes, I am running a DHCP server ('dhcpd') that comes with RH9.0. I'm
trying to configure it to serve other clients on a 'home' network IP
addresses as needed, and it's turning into a bit of a nightmare
(seeing as I know very little about setting up a network).

I botched a way around this by adding overriding commands to the
/etc/rc.d/rc.local file, but I still want to know *where* those other
configuration commands are coming from, how they got there and why I
can't make them disappear. Call me picky, but...

Umm, haven't tried that, but redhat 9.0 script /etc/rc.d/rc3.d/S10network
does seem to check for existance of file /etc/sysconfig/static-routes file,
and to honor it if present.

Yes it does! Strange. That would not work for me. Now I wonder why. The
/etc/sysconfig/network-scripts/route-eth(x) does indeed work.
