$ifdown and up for a user rights


Hello

Why don't you try the following:

1. Create a new group for those designated users (in my example, dialup) and add the users to that group.
2. Change the group to which the ifup and ifdown belongs, for example: #chown root:dialup `which ifup`;chown root:dialup 'which ifdown'

I did all I can but I am not able to use ifup/ifdown as a user, note;

[/home/sam] ls -l !$
ls -l /sbin/if*
-rwxr-xr-x 1 root root 58380 Jul 1 05:52 /sbin/ifconfig
-rwxr-xr-x 2 root dialout 26400 May 3 2005 /sbin/ifdown
-rwxr-xr-x 1 root root 3852 Apr 4 2002 /sbin/ifport
-rwxr-xr-x 2 root dialout 26400 May 3 2005 /sbin/ifup
-rwxr-xr-x 1 root root 4716 Apr 4 2002 /sbin/ifuser
[/home/sam] groups sam
sam : sam dialout cdrom floppy audio dip src
[/home/sam] exit
exit
sam@das:~$ ifup eth0
bash: ifup: command not found
sam@das:~$ /sbin/ifup eth0
/sbin/ifup: failed to open statefile /etc/network/run/ifstate: Permission denied
sam@das:~$ su
Password:
[/home/sam] ls -l /etc/network/run/ifstate
-rw-r--r-- 1 root root 6 Nov 8 20:13 /etc/network/run/ifstate
[/home/sam] chown root:dialout /etc/network/run/ifstate
[/home/sam] exit
exit
sam@das:~$ ifup eth0
bash: ifup: command not found
sam@das:~$ /sbin/ifup eth0
/sbin/ifup: failed to open statefile /etc/network/run/ifstate: Permission denied
sam@das:~$ su

Ok... seems good, just check that you changed the ifup group (which is good) but the permissions on /etc/network/run/ifstate are Read-Write for owner (root) but still just read for group (should be Read-Write as well).

Adding user `root' to group `dialout'...
Done.
