I`m another adsl user who had the same problems regarding internet connection.
After reading trough the tread i saw that some things changed again :S (su-), on top of all rp-pppoe pisi isn`t included in pardus package installation process. It is true that majority of users don`t use adsl anymore but still there are few that need pppoe pisi to get internet connection going. From new user point of view this can be a very important aspect especially if this user doesn`t use dual boot with windows, he is basically left in the dark to do his own research. Another thing is command line tools for new user is a no go, there is a big posibility that they will freak out and ran to another distribution or back to windows (point and click mentality).
@ alvx: Regarding setup of the internet connection, you seem to have quite a few experiences with different distros, I`m glad to hear you got connection up and going.
Here is another way how to get connection up at boot time
1. open console and login as root
2. use konqueror or mc to make copy of sudoers file. back it up to another location prior to editing it.
3. open sudoers file located in /etc with your favorite text editor
4. edit sudoers file to look like this
# sudoers file.
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the sudoers man page for the details on how to write a sudoers file.
#
# Host alias specification
# User alias specification
# Cmnd alias specification
# Defaults specification
# Runas alias specification
# User privilege specification
root ALL=(ALL) ALL
# Uncomment to allow people in group wheel to run all commands
%wheel ALL=(ALL) ALL
# Allow members of the group "dialout" to connect to the internet:
%dialout ALL=(ALL) NOPASSWD: /usr/sbin/pppoe-start, /usr/sbin/pppoe-stop
# Same thing without a password
#%wheel ALL=(ALL) NOPASSWD: ALL
5. the key line that must be added is
# Allow members of the group "dialout" to connect to the internet:
%dialout ALL=(ALL) NOPASSWD: /usr/sbin/pppoe-start, /usr/sbin/pppoe-stop
6. save it and exit
Second part consists of making yourself an executable script that will be started at boot time
1. open your favorite text editor and
2. copy this lines in to it
#! /bin/bash
# dsl start
sudo /usr/sbin/pppoe-start
3. save the file and name it like you want (ex. adsl-start)
4. right click on the file ----> properties----> permissions tab----> make a tick in the is executable box----> confirm the changes
5. open console you can use mc to navigate to ~/.kde3.5/Autostart
6. find your script and copy it to location mentioned above
7. restart your computer and try if it works
8. if you want you can make another script for disconnecting your connection
#! /bin/bash
# dsl stop
sudo /usr/sbin/pppoe-stop
p.s. I can`t confirm that this is working on pardus 2008 but I`m using it daily on 2007.3 and other distros, so it should work without any problems
