This document describes three different ways, each of them differ in difficulty to set up and the implication on security.
This document assumes you have Template:Codeline properly configured.
This is arguable the easiest setup but has major impact on system security since it means that every user can run wvdial as root. Please consider using one of the other solutions instead.
As normal users can't use wvdial to dial a ppp conection by default, change permissions:
chmod u+s /usr/bin/wvdial
You should see the following permissions:
ls -l /usr/bin/wvdial -rwsr-xr-x 1 root root 114368 2005-12-07 19:21 /usr/bin/wvdial
Using a dialout group
Another, slightly more secure way is to set up a group called dialout (call the group as prefered) and give members of this group permission to run Template:Codeline as root.
First create the group and add the users to it:
# groupadd dialout # gpasswd -a username dialout
Then set the group and adjust the permissions on Template:Codeline:
# chgrp dialout /usr/bin/wvdial # chmod u+s,o= /usr/bin/wvdial
The files should have the following permissions: Template:Command=ls -l /usr/bin/wvdial
- See main article: sudo
sudo arguably offers the most secure option to allow regular users to establish dial-up connections using Template:Codeline. It can be used to give permission both on a per-user and group basis. Another benefit of using Template:Codeline is that it is only needed to do the setup once; both previous solutions will be "undone" when a new package of Template:Codeline is installed.
To give a specific user permission to run Template:Codeline as root, add the following line (changing the username):
username localhost = /usr/bin/wvdial
To give all members of a group (Template:Codeline in this case) the same permission:
%dialout localhost = /usr/bin/wvdial
