[SOLVED] netcfg. DHCP and default gw

Hello!

I have got the following problem on my workstation. I'm getting IP via DHCP but it does not set proper default gateway. So, every time I boot my machine I have to run the following:

sudo route add default gw 192.168.234.254

Is there any way to make it automatically on network start? Btw, I'm using the following netcfg profile:

CONNECTION='ethernet'
DESCRIPTION='A basic dhcp ethernet connection using iproute'
INTERFACE='eth0'
IP='dhcp'

I've tried to append the line to network profile:

IPCFG=('route add default gw 192.168.234.254')

but got an error:

Error: either "to" is duplicate, or "gw" is a garbage.
 > Could not configure interface (route add default gw 192.168.234.254).

Thanks.

Re: [SOLVED] netcfg. DHCP and default gw

You need to look at why you're not getting the default gateway set via dhcp - workarounds as above are not solutions.

If you run dhcpcd manually, do you get the right gateway?

I've already asked our office's sysadmin but he has not got any solution yet.
If I run dhcpcd manually I do not get the right gateway either.

Wouldn't DHCP_OPTIONS="-G 192.168.234.254" in your Netcfg profile do the trick?

What does netstat -rn say? FWIW, with a setup as simple as yours, I would blame the router you are getting an IP from...

Still no luck

Cool, but I meant before you set up the route manually...

But this is the output before I set up the route. After I set up the route netstat outputs the following:

Re: [SOLVED] netcfg. DHCP and default gw

Solved! Added the following line to my netcfg profile:

POST_UP='route add default gw 192.168.234.254'
