[NTLUG:Discuss] ppp

[Mike]

I had a similar problem trying to use the gui-centered kppp 
that came with SuSE 6.0 instead of the SuSE recommended 
wvdial (ugly command line.. settings buried deep in system 
settings program for SuSE....) 

to start with check for errors:

$tail /var/log/messages

This will give you an idea where the problem lies ...

I was having a 'cannot create lock file' error due to wvdial 
already having the ppp lock file tied up permanently 
somehow with permissions.  If I remember right, I could fix 
it by deleting the wvdial owned file, but everytime I ran 
the system setup program (YAST) for any reason, SuSE would 
find my changes and lockup the ppp lock file for wvdial 
only.

I fixed my problem on SuSE by uninstalling the rpm for 
wvdial and the rpm containing kppp, then reinstalling the 
rpm for kppp and letting the dependencies take care of 
themselves. Once done I had to do some setup of permissions 
on the lock file.. but kpp could access it and the setup 
program would leave the lock file alone. 

This is several versions back.. but the starting point 
should still be valid..
