What would be the best way to record port logins...

[LeePatto]

...for example, when an application accessed the AIX Server over a specific port. I can currently use netstat -a to list connections. Is there a better way? Also, is this information written to a logfile anyway, like wtmp records logins?

Many thanks

lsof | grep TCP

is what I use but I'm not sure it has any benefits over netstat -a

Hi there, lsof doesn't appear to exist on my servers. So there is no logfile that records this..? I'm not aware of one myself. All incoming connections from applications will be on "TCP"? I'm not showing any on uppercase TCP, but plenty on lowercase "tcp"?

Thanks
