User name always listed when 'finger'...

I use telnet to connect my ISP - UNIX(r) System V Release 4.0 under win95,(after using dial-up networking) but when I did the same thing next time and run 'finger' command, I found two of my user names showed there, the other one had an 'Idle ' time of a couple of days.  Why? And how can I eliminate the 'un-dead' one?

Thank you for your advise.

ezlee,

- I believe the server has not been rebooted since the date of the idle time recorded in finger or   else this phantom users will be cleared off.

- This phantom users might be caused due to several reasons :
  ** improper logout
  ** background process - if you accidently press Ctrl-Z, provided enable in .profile
  ** a sudden network down (e.g. router down) when you're processing something.

- You can check using "ps -ef" (in HP-UX) or "ps -ax" (in Sun), grep for the tty id (get it from     finger) and see what's the process(s) being run at that particular moment. You can pretty sure    know what you were running previously before the hang from this.

Thanks, fredfan.
But my ISP won't let me run the command, it uses AIpink2.1 Pink and only show me a menu to limit commands i can use.

I use 'finger' and see "tty id: pts/6,  Shell:.../pink" for the un-dead user name.
So, who can I kill it?

ezlee,

- instead of me guessing what are the options available in your ISP menu, wonder if you're kind   enough to post it here.
- there're a lot of ways to get the proc id before kill the phantom process but do you have option   to KILL in your menu ? If not, don't think you can do anything except to inform your ISP. Unless   you can break into shell prompt ....
