ppp link time limit

ppp link time limit

[Davy Leon]

Hi guys

I have a link wich I stablish by running

pppd call isp

It' launched by the cron at some scheduled times of the day. I need the link 
doesn't stay up for more than 30 min, but doesn't know how to do that. No 
matter the link is idle or being used I want to terminate it once reached 
the ammount of time specified. How can I do that?

Cheers

David

       maxconnect n
              Terminate the connection when it has been available for
network
              traffic  for  n  seconds (i.e. n seconds after the first
network
              control protocol comes up).

pppd call isp & sleep 1800; killall pppd

The above will kill any pppd process, not just the backgrounded one from 
this shell script.

#!/usr/bin/perl

my $pid = fork();
exit 0 if $pid;

$pid = fork();

if($pid = 0) {
  exec "/usr/sbin/pppd", ("call", "isp", "nodetach");
  exit 1;
}

sleep 1800;
kill 15, $pid;

I should probably port this option over from the OpenSolaris variant of
pppd:

     maxconnect n

         Terminate the connection after it has been available for
         network  traffic for n seconds (that is, n seconds after
         the first  network  control  protocol  starts).  An  LCP
         Time-Remaining  message  is  sent  when  the  first  NCP
         starts, and again when 5, 2, and 0.5 minutes are remain-
         ing.

Without that option, one way of doing what you ask is to use the
"linkname" parameter to force a reliable PID file name, and then just
sleep and kill the process based on the contents of that file.

Yes, using maxconnect is probably a better idea if you have multiple pppd
running.
