<<< GYRO::SYS$SYSDEVICE:[NOTES$LIBRARY]INTERNET_SERVER.NOTE;1 >>>
An Internet-service provider seeks an indicator of ppp inactivity
(say over 15 minutes) to trigger a timeout and forced logout. DU
version is 4.0.
Here is a patial listing of the output of ps -e -O sl,RUSAGE
that's relevant to the pppd. Note that the 'sleep time' (SL)
for the pppd varies between 1-59 seconds and then appears to
invariably reset. I'm not sure what the purpose of such a reset
would be (assuming this is a "feature"), but in any case this
potential indicator is rendered useless for inactivity measurement.
1. Am I missing something?
2. Is there some other indicator to accomplish the desired end?

Hi, If I recall note 8140, Farrell wrote: "ppp's "timeout" mechanism is a means of monitoring the sanity of the link" I think that's why the sleep times keep resetting, because these timers are going off continuously. Looking at the ps output you've collected, I think there might be a simple solution to finding the tty idle times. Cross-referencing ps with 'w' output in a script will give you the idle time of the tty: # w User tty from login@ idle JCPU PCPU what haley console 11:02 2days /usr/sbin/get haley p4 11:03 27 5:37 13 -csh haley pa 15:05 26:31 rlogin abelia ... Unless pppd's timeout is resetting these :-( There are other ways too, but this fits well in a script. -Brian [Posted by WWW Notes gateway] | |||||
