Dear Nick,
That make sense. There is actually auth-up and auth-down script files with my
distribution of RedHat 5.1.
The reason why I want to have a real user name in utmp is because I want to track
online
time and traffic of users and ACUA (the program I want to use) needs a real name there
otherwise it does not know who to charge or actually does not charge anyone.
AutoPPP is actually putting a name (a_ppp) in the utmp file (or is it the wtmp file.
Which one is read by the "last" command?).
So what would be the harm in putting a real user name in there instead. In fact who
cares, if we know that /AutoPPP has acticated this interface. Don't we want to know who
is using the link?
If you have any suggestion on what the scripts could look like, please advise. Your
help
is certainly appreciated.
Regards
Bernhard
