sudo on CT0

[gm2x]

I've installed sudo on proxmox hardware node. Now i'm getting error messages when trying to use it.

$ sudo ifconfig 
sudo: ifconfig: command not found

Meanwhile the next command is perfectly working.

$ sudo /sbin/ifconfig

I understand that this is a $PATH issue. Trying to troubleshoot more:

$ env | grep PATH
PATH=/usr/local/bin:/usr/bin:/bin:/usr/games

$ sudo env | grep PATH
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin

The same output on regular Debian installation. Checked ~/.bashrc, /root/.bashrc, /etc/bash.bashrc files on both systems, they are all the same. What can i check else?

$ sudo env | grep PATH
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin

So /sbin is already in PATH?

 

[dietmar]

already tried 'sudo -i' ?

Already. Running 'ifconfig' inside root shell works.

So /sbin is already in PATH?

It is for root accout, but running 'sudo ifconfig' as a regular user isn't working. I have no ideas why... And i have no ideas what makes it work in regular debian installation. How 'sudo <command>' finds the command that isn't in path.
