If you're already connected and your system has an ip address, you can use the ifconfig command

No. Look closer at the spelling. It's ifconfig not ipconfig. As in InterFace CONFIG. If you just type ifconfig by itself, it should list all the information about all of your interfaces, including the ip addresses of each one. You'll also see a bunch of other info, like MAC addresses, Transmission/Reception stats etc.

You may also try adsl-status. This should work if you are using pppoe.

its:
/sbin/ifconfig

where do you modify the path so that when you login you don't have to keep entering /sbin? That way you can just enter ifconfig...

Thanks

Usually in the .bash_profile in your home directory. There should be something like this in there:

PATH=$PATH:$HOME/bin

Just add it to the current path with a colon separating the individual paths. So it would look like this when you're done:

PATH=$PATH:$HOME/bin:/sbin

To be honest though, having /sbin in your path, might not be a great idea. In order to use alot of those commands, you'll need root priveledges. You'll be able to execute the command, but it won't work real well. For example:

Code:

$ whoami
icarus
$ echo $PATH
/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/icarus/bin:/sbin
$ifconfig eth0 down
SIOCSIFFLAGS: Permission denied

Well that didn't work let's try something else

Code:

$ chkconfig --level 345 yum on
failed to make symlink /etc/rc3.d/S50yum: Permission denied
failed to make symlink /etc/rc4.d/S50yum: Permission denied
failed to make symlink /etc/rc5.d/S50yum: Permission denied

Get the picture. I can execute stuff, but I need to have root priveledges for the underlying system calls to work. Plus it would probably make it much easier to bork your own system. I'd stick with just doing su - to become root and then run the commands in /sbin

Great advice! I could make your path changes under root right? That way when I login as root I won't have to enter the path to the commands. That should be OK right? Or is it just really better to always enter the path?

Thanks again!

Root should have /sbin in his path, at least I've always had it in there by default. It might be different on your distro or something. If it's not, you can go ahead and add it if you want. Personally I think it's just easier than typing out the full path every time I need one of those commands. I guess there might be reasons why you wouldn't, but I think the benefits outweigh the risks in this case.
