Setting IP address by command line

[Guest]

Is there a way to set my IP address and gateway information by command line? I'm having a problem with Knetworkmanager connecting me or even letting me manually configure my network settings. The knetwork problem seems to be somewhat of a common problem with HH from what i'm seeing on the forums.

Thanks,

Re: Setting IP address by command line

yes.

you can set up networking manually from the command line.

you need to use different commands and do different things
depending on whether you're talking wired or wireless, though.

and things also depend on how you're setup modem/router wise.
if it's static ip or dhcp, for example.
stuff like that.

but what is it that's not working right now?
could you describe your setup and problems?

oh, and post the result of:

ifconfig -a

to see the current if status

netstat -rn

to see the routing table

cat /etc/network/interfaces

to see the network if configuration file

cheers

Re: Setting IP address by command line

Yesterday i was playing around with this and I was getting an invalid gateway error, if your getting the same problem here is the possible solution:

1. Configure your static ip under the Network Interfaces tab including advanced settings (broadcast address example for 192.168.1.x 255.255.255.0 192.168.1.255)

2. Go to the Routes tab and set the default gateway there as well.

Here are the results of ifconfig -a:

And Netstat -rn:

0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 eth0


And /etc/network/interfaces:

auto lo
iface lo inet loopback


All I am trying to do is set up a static IP address with a gateway and two dns servers. The problem is that knetworkmanager will start up, but won't keep a connection nor will it let me do a manual config. This is wired btw.

Re: Setting IP address by command line

guess it's avahi that's causing troubles.

i would suggest to remove avahi and see what happens.

sudo apt-get autoremove avahi-autoipd avahi-daemon

it will want to remove a couple of other packages.
including kubuntu-desktop.
just go on and confirm.

restart your system (it's is not really necessary, but easier).

see if you can configure you network statically from knetworkmanager now.
