Log all connecting users
How can I log all connecting users an log it to a file?
For example:

The user 'megan' login to the machine 'client1' with rlogin.

How and where can I see that she used the rlogin protocol and that her username is megan?

Help..!

on which os? but commands like "who" and "ps" should help... under solaris10 dtrace is possible to use for what you want!

I'm more looking for a way to see this in a logfile in realtime, like a daemon that listens for user logins and what protocol they use and then put that in a file.
(I use solaris 8)

maybe you should write a script and run it via crontab... but for realtime? i don't know....

found something that should work:

just a pointer,

get the pids of daemons such as telnetd, sshd and other
accepting connections and granting ttys

periodically check for any child process of the parent pids extracted above.
From the child pid and ps info, can extract few information.

Not sure if this bash script is of any use to you but it will print all users and processes.

Code:
finger |
awk '{ if (NR > 1) print "echo " $2, $3}
{if (NR > 1) print "ps -U ",$1} ' > myfile
sh myfile
rm myfile

output similar to below

Code:
Jack Jones

PID TTY          TIME CMD
22339 ?        00:00:01 sshd
22340 pts/1    00:00:00 bash
30515 pts/1    00:00:00 sh
30521 pts/1    00:00:00 sh
30522 pts/1    00:00:00 ps
