New group for special priviledges

linmix · 01-04-2005, 04:48 PM

I'm using kppp to access the internet and would like to be able to use it without having to use the root password.

I've created a new group:

Code:

# groupadd internet

to create a new group (gid=501 - should I have used the -r flag to make it a system account?)

I've tried to add myself to this group by (after reading the man page) giving the following command:

Code:

[root@localhost ~]# adduser -G internet linmix
bash: adduser: command not found
[root@localhost ~]# whereis useradd
useradd: /usr/sbin/useradd /usr/share/man/man8/useradd.8.gz

So in the end I did it using the Gnome user manager (why idnt' my command work?)

Then I tried the following:

Code:

# chown root:internet /usr/bin/kppp
# ls -l /usr/bin/ | grep kppp
lrwxrwxrwx   1 root root          13 dic 25 12:14 kppp -> consolehelper
-rwxr-xr-x   1 root root      181580 sep 30 00:53 kppplogview

... no reaction because kppp is only a link?
So I did

Code:

chown root:internet /usr/bin/consolehelper
# ls -l /usr/bin/ | grep consolehelper
<snip>
-rwxr-xr-x   1 root internet    5636 oct 20 11:15 consolehelper
<snip>

I managed to change the group, but when I try to start kppp I still need to give the root password.

What am I doing wrong and how can I give myself access to kppp without making it free to all?

Note that "useradd" is not the same as "adduser" (see your code)
To add your user to the "internet" group: perhaps you could edit your /etc/group file and append your username to the group (see also "man group")
Just a thought.

strangely enough "man adduser" takes me to the manpage of useradd.

ANyway, I alrady managed to add myself to the new group through the GUI user manager (see my post).

The question remains: how do I make kppp available without root priviledges to a specific number of users?

Allow the internet group access to kppp

Code:

chgrp internet /path/to/kppp

All the internet group access to /dev/modem (your may be different)

Code:

chgrp internet /dev/modem

Allow them executable access to kppp

Code:

chmod g+x /path/to/kppp

At this point, it should be donw. Although, they might need read, or even executabel access to /dev/modem, so if that doesn't wrok this this:

Code:

chmod g+r /dex/modem

Then this
[code]chmod g+x /dev/modem]
