 Posted: Sat Jun 19, 2004 8:36 am Post subject: Unable to run some commands even while SU |
 |
|
Hello again. I use ndiswrapper to utilize my drivers for the wireless card I have, so often times when I boot into a linux distro I have to run the modprobe/ifconfig commands to get my card 'online.' However, I've noticed that when I'm logged into my user account I can't use these commands, not even when I SU. I don't remember this happenening at first, but it happened again tonight for the second time I think. I can log out of my user account (magnet) and then log in as root and get my stuff working, but that's kind of inconvenient and I don't see why I can't use the commands as 'magnet' anymore. Any ideas?

This is getting obscene. Maybe I never could use those commands while logged in as a regular user...but I swear I could. Either way I've reinstalled to start anew, to see if it was something I did that screwed it up, but I still can't do commands like modprobe and iw/ifconfig. And now I can't seem to mount my windows partition correctly. I added the same entry to /etc/fstab as I did last time, and last time it worked...but now it doesn't. Well, let me clarify...last time I could read files in the mounted windows dir (I mounted /dev/hda2 to /mnt/win) when I was logged in as the normal user. Now I can't. It seems like I can only do anything I'd like to do when I'm actually logged in as root (not SU, I've tried that).
What's happening? :( Please help I'm getting very frustrated.

The reason you can't run the commands when you `su` to root is that they are not in your $PATH.
There are a couple solutions. I'll use `ifconfig` as an example.
will give you:
"bash: ifconfig: command not found"
will run ifconfig. The "-" means to read in root's environment variables, which adds /sbin to the path.
This will also run ifconfig, since an absolute PATH is specified.
Another approach would be to add /sbin & /usr/sbin to your own PATH.
vi .bashrc (or whatever editor you use). Add the line:
| Code: | | PATH=$PATH:/sbin:/usr/sbin |
Once you log out and back in, these will be your settings, so you won't run into command not found when you run stuff in /sbin & /usr/sbin

Thank you very much good sir about the commands. Do you know what happened to my ability to view the mounted partition though? It's a big inconvenience to be unable to access it in programs like XMMS as a regular user.

Okay, never mind the mounting stuff. When I edited my /etc/fstab again I placed the wrong command there, so 'magnet' couldn't see it. But I've got it working now. Thanks again.
