Can use wvdial as user

Vlad_M · 10-02-2002, 02:29 PM

I am using RH7.3, and wvdial to dial up to my ISP. For some reason, GPPP and KPPP don't work with my modem. No matter, wvdial works fine. The only problem is that I can't use wvdial as a user, only as root. If i try as user I get this:

can't open /dev/ttyS0

I have tried changing the permissions for wvdial, even for /dev/ttyS0 ( i don't even know if that makes sense) and still no go.

I know that this is something trivial, I just can't seem to find what I need to change.

Can anyone lend a hand?

Thanks,
Vlad.

please post the permissons for /dev/ttyS0 and wvdial program. Sounds like your user is not in the correct group to use it, or the permissions dont allow anyone to do it.

Im runnind wvdial fine as a user. Here are the permissions:
--(Wed Oct 2, 22:01:04)--(nskl@SlackBox:/dev)$ ls -l modem
lrwxrwxrwx 1 root root 5 Aug 6 22:22 modem -> ttyS1
--(Wed Oct 2, 22:01:11)--(nskl@SlackBox:/dev)$ cd /usr/local/bin/
--(Wed Oct 2, 22:01:30)--(nskl@SlackBox:/usr/local/bin)$ ls -l wvdial
-rwsr-xr-x 1 root root 60524 Aug 9 14:21 wvdial*
--(Wed Oct 2, 22:01:36)--(nskl@SlackBox:/usr/local/bin)$

Ok, I checked the permissions, and i did chmod 7777 /dev/ttyS0 and the same for /usr/wvdial. Then it dialed, but it disconnected right after authentication with the PPPD code 2.

I know that I am screwing up with the chmod somewhere. Can someone (like NSKL

) give me the exact chmod (I understand the 9 least significant bits, its the most significant three that i don't know what they do) that I should use on these two files?

edit : fixed a typo

From PPPD man page: Exit status:
2 An error was detected in processing the options given, such as two mutually exclusive options being used.
Are you sure pppd is setup correctly?
Anyways all i did is chmod a+rwx on /dev/modem (linked to ttys1) so i chmoded them both, as well as wvdial binary. all chmod a+rwx but beware, this is giving permissions to everyone to use these files, i'm the only user on this computer, so local security is not of a concern, but if you have more useres you might want to created a dialup group and add your user there.
Hope that helps, ask if you needm more help

Yeah, I know what the error is and that's what baffles me. Wvdial is working 100% if used as root, and then it gives that if I use it as user. The thing is that it's using the same file, /etc/wvdial.conf, and before you ask I did change the permissions of that file as well.

Strange, strange, strange...

Anyone have any suggestions?

In the corber of my mind i remember changing some more permissions, on a file called options, or ppp.options or options.conf, you get the point.. but for the life of me i cant find it any more....
Ahh here! /etc/ppp/options
try that and see what happens.

Yeah, managed to sort it out. It was the /etc/ppp/otions, but then it still didn't work. The /etc/ppp/pap-secrets also needed to be changed. Now it works.

Thanks NSKL for the help!!!
Cheers mate!
