Please help me - when I try to connect (dialup) under GNOME in Fedora Core 6 with gnome-ppp as user, cannot access /dev/ttyS0 (my modem's serial port), but as root there's no problem, evertything works fine !!!

Any ideas what could be the problem?

Thank you for your help.

You may not have read permission for the device. Type the following command and tell me what you get:

ls -l /dev/tty*

They should return:

crw-rw-rw-

Notice what group the device belongs to. If it belongs to the dialout group then you will need to add your account to the dialout group in the /etc/group file in order to have permission to read and write to the device.

I get this: crw-rw----
So I added my user to that group, but it didn't help.
The chmod command didn't work on this file. Maybe because it is just a link?

Thanks.

Its not a link if it starts with
c
(crw-rw----) these are the permissions that they should have (not full rw otherwise there is no need for a group)
You have to add your user to the group of this file (can be dialup, uucp or anything) so be sure to check the group. It depends on your configuration.
And then add your user to THIS group.
And then you have to restart gnome at least. because the ownerships get inherited for a login shell only.
Check that your user is in this group by typing
id


For the rest of ppp, it should run as root (it should be automatic) because ppp needs to override files which only belongs to root.
