I am using debian 1.31 Linux with xisp for ppp connection. ppp works fine
when I log in as root, however, when I use other login name pppd exits
immediately. I DID change mod of /usr/sbin/pppd using 'chmod u+s
/usr/sbin/pppd'. Is there other file that I need to change mod to use
ppp as a nonroot user? thanks in advance.
