Bug 87687

why do you set so many default routes? default routes are there to define the
route to any network.
I guess you have private networks on eth0 and eth1. So why don't you set network
routes for them instead of default gateways???

I didn't set the default route... Thats what I'm talking about.
Somehow the startup or "ifup eth1" is setting the default route.
The settings for all devices are configured with neat.
I can not find any configuration option that would say "set as default route"

It won't matter in another week or two because I hopefully wont be needing the
modem.  But I don't get why starting up eth1 should decide to install itself as
the ANOTHER default route. (There is already a default route in the routing table)

If this was connecting to another network then I would use a gateway setting!
But at the moment it is just another ethercard. And I only want the static route
entry NOT the default route entry.  I can manually delete it in the post startup
script but that is a pain. I only want the one default route at the moment for
the internet and that is set by pppd which is also configured through neat.

Here is the ifcfg-eth1 file

# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
USERCTL=no
BOOTPROTO=dhcp
HWADDR=52:54:05:e3:c5:5a
DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
NETWORK=192.168.0.0
BROADCAST=192.168.0.255
PEERDNS=no

On the end of this cable is a new adsl modem that supplys the ip etc.

I was wondering where the default route option is coming from. Especially
considering the fact there is already a default route in the routing table for
the ppp0 link.

Thanks

show me 
$ route -n

With eth1, lo and ppp0 on

Now with eth1 also activated

I also have to start this interface up from the command line using "ifup eth1"
and it doesn't seem to complete the operation corectly it just pauses. I have to
hit cntrl-C to quit out of the "ifup" command. 

The only place I can see where a default route is set in the "ifup" script is
when the following does not return true "if [ -n "${DYNCONFIG}" ];" and the
default route is set at the end of the "else" area for this test.

It could also be the fact that the GenMask set through the DHCP negotiations is
effectively setting the routing address range. But I dnon't really know enough
about that to say.
I'd be happy if ppp0's default was first :)

Thanks

hmm... this is done by the dhcp client dhclient...
you may have to change that behaviour in /etc/dhclient.conf.
This is not a bug... this is a dhcp configuration issue.
But, this should maybe be made configurable more easy...

Thanks
I'll take a look and get back to you.
I wasn't sure about it.
By the way this Network Config tool is excellent, it sure makes my job easier :)
