[NTLUG:Discuss] cannot execute /usr/bin/perl /etc/vocp/vocp.pl

Tue Nov 29 08:15:39 CST 2005

Robert and All:

Use ps -uaxf, I see the root is running the vgetty.
It is always running.
In other words, It always listed when doing ps command
no matter if I am calling the modem or not.

Modem is set to /dev/ttyS0
the log file was generated when I make a call.

Is there any way to monitor the new process/program created
(like windowz task manager in kde or console) in real time
so I can check when I make a call and who is executing the vocp.pl?

Thanks.
