Some General Tips
•
The permissions on pppd have to be changed to suid root if other users besides
root are to be able to make PPP connections. This is the same with KPPP. An
alternative is to create a “modem” group and give read/write permissions to that
group. Then add the users who are allowed to use the modem to that group.
•
A secure way to start up PPP is to make a login specifically for PPP access whose
shell is a call to pppd.
•
Starting pppd with the “debug” option prints some informative information to
the screen
•
The KPPP FAQ provides some good additional troubleshooting tips.
