1. PPP for non-priveliged user

Hello,

I recently upgraded from a plain RH 5.0 system to an equally plain RH
6.0 system. On the old RH 5.0 system I eventually got PPP working, and
so I thought I would copy these settings / scripts over to the new
system.

This has worked quite good, but the problem is that only root can
invoke the Connection, wheras on the old setup all useres could start
the ppp - connection. When a non-priveliged user tries to start a ppp
connection on the new system it stops with the message :

  Permission denied: Failed to open /dev/ttyS1     (<- not verbatim)

Where /dev/ttyS1 is my modem connection. The connection is innitiated
from the script /etc/ppp/ppp-on. To try and give all users ability to
open a ppp connection I have:

 o chmod a+r /dev/ttyS1
 o chmod u+s /sbin/pppd & chmod u+s /usr/bin/chat
 o chmod u+s /etc/ppp/ppp-on
 o Written a miniature C - program to call "/etc/ppp/ppp-on":

     #include <stdlib.h>
     int main () {
        system("/etc/ppp/ppp-on");
     }

   And set this program to suid root.

   However - this program was written, and _compiled_ on a RH 5.0
   system. I chose not install C-development packages on the new
   system, and suddenly I found myself without a C-compiler. (OK - that
   was a bit naive.)

(I might have got the path to pppd and chat incorrectly here, I'm not
at the box in question right now.)

But - nothing seems to work. Does anyone a have any further
suggestions on how to get ppp to work for non-priveliged users? Or
maybe people generally do a "su" before they start ppp?  If that
matters - my ppp connection is plain vanilla without either chap or
pap authentication.

-----------------------------------------------------------------

Finally, what is people's experience with Netscape 4.51, previously I
had Netscape 4.03/4 - and it generally worked nicely. However the 4.51
has a mean time between failure in the miniute-range - I have a vauge
suspicion java is lethal ??
