Hi,
How difficult would it be to configure an alert on AIX that will inform me every time someone logs into the system?
You could use syslog.
Create a named pipe:
mkfifo /var/log/auth_pipe
Edit your /etc/syslog.conf; add something like
auth.info /var/log/auth_pipe
Refresh your syslog to read in changes to it's config:
refresh -s syslogd
and then you can setup a cronjob for example, that reads out the named pipe to send you a report. You can also use a local username instead of a named pipe to get the messages directy displayed on the screen/terminal while they happen (can be quite disturbing) or you can use a plain file instead of a pipe which you can check later.
The file or named pipe has to exist before you do any changes/refresh to the syslogd.
Beware from deleting the entry for errpt
