Connecting to net as a user won't work
 
For some reason, I can't connect to the internet when I'm logged in as a user. So I always have to log out and sign in as root. Then it works. This is the error message I get when I use KPPP when logged in as a user...

You do not have sufficient permission to run
/usr/sbin/pppd
Please make sure KPPP is owned by root and has the SUID bit set


Now, I'm new to Linux so I am completely lost as to what this says. ;) So how can I use KPPP signed in as user? I'm getting tired of constantly signing back and forth between the bloody accounts. :cry:


Oh yeah, I'm using openSUSE 10.2 if that helps anyone.

First, try running YaST2. There may be a ppp config program that will do this for you.
Second, locate the kppp program. It probably is somewhere in /opt/kde3/bin/ or /opt/kde3/sbin. Look at the long listing of it, i.e. "ls -l /opt/kde3/bin/kppp"
It will be owned by root. But look at the group owner of the file. It might by owned by "kppp". If so a member of the group kppp will be able to run the program.

Update: I googled on "suid" to refresh my memory on the chmod command to set the suid bit. I found out that the solution is to make yourself a member of the "dialout" group.
So setting the suid bit for the kppp program is probably not the correct thing to do, so I won't even post the third option.

I'm not at my Linux machine now so I wasn't able to locate the kppp and pppd programs and look at them.

Hi,
another alternative which is use setuid method(not recommended if you share computer with other user),
as root,
chmod +s /opt/kde3/bin/kppp

so next time you will automatically run kppp as root.

Regards,
Ks

Using the dialout group is a much better solution. You should never have to suid a program like kppp.
