Subject: PPP permissions

I can't figure out how to give normal users access to the Internet. 
I've created a script that runs my connect command, and put it in
/usr/bin.  I tried it, and as a normal user it said that PPP wasn't part
of the kernel (which was absurd, of course, because I could log on to
the internet with no problems as root).  So I scoured dejanews a little
bit, and came up with some things that didn't work, such as chmod 4755
pppd and chmod 666 /dev/modem and chmod 4755 /dev/modem.  I've also run
across some posts describing a pppd.users file in /etc, but I didn't get
enough info to try creating it myself.  Anyone know how to get normal
users access to the internet?  And on a side note, anyone know what
permissions are default for /etc/ppp/pppd and /dev/modem, since I would
like to set them back to what they were originally.  And is there a way
to shut down the connection to the Internet without having to do ps,
then kill the process number?

Regards,

Mladen
