PPP: I give up

[hwalton]

When I try to run my PPP scripts, everyone of them results in permission denied.   I did edit the /etc/group file and added my user name as follows:   dip:x:40:hwalton   I still get permission denied? Can anyone figure what is going on here?   I did logoff than log back on.   I also tried the following commands:   1. chmod g+x /etc/chatscripts   2. chmod u+s /usr/sbin/pppd   None of it works...I am ready to tear my hair out!
