Steps to track disconnects
1. On the pm3, set loghost <ipaddress>. e.g. set loghost 192.168.1.1
where ipaddress is a machine that is running syslog
2. set syslog te <syslog facility>. e.g. set syslog te local7.info
3. On your syslog box, add the following to syslog.conf
local7.info <tabs, not spaces> /var/log/pm_term
Then, create the following script. e.g. pm-term.pl
#!/usr/local/bin/perl5
#
# Script to check syslogs for PortMaster 3 disconnect reasons.
#
# Reads logs from standard in and writes info to standard out.

# You can modify this at will, but please send me any improvements you
# make.
$discon{"normal"}=0;
while (<>) {
if (/terminated - (.+)$/) {
$reason = $1;
# The next set of lines makes this script ignore what can be considered
# "normal" disconnect reasons. Comment out or delete any you want
# reported.
if ($reason =~ "Auth Failed") {$discon{"normal"}++;$total++;next;}
if ($reason eq "Admin Reset") {$discon{"normal"}++;$total++;next;}
;
if ($reason eq "Host Request") {$discon{"normal"}++;$total++;next;}
;
if ($reason eq "Idle Timeout") {$discon{"normal"}++;$total++;next;}
;
if ($reason eq "Session Timeout")
{$discon{"normal"}++;$total++;next;} ;
if ($reason eq "Login Timeout")
{$discon{"normal"}++;$total++;next;} ;
if ($reason eq "User Request - PPP Term Req")
{$discon{"normal"}++;$total++;next;} ;
if ($reason eq "User Request - Normal LAPM Disconnect")
{$discon{"normal"}++;$total++;next;} ;
$discon{$reason} = 0 if (! $discon{$reason});
$discon{$reason} ++;
$total ++;
}
}
foreach $reason (sort {$discon{$b} <=> $discon{$a}} keys %discon) {
printf "%50s %5.2f%% %5d/%d\n", $reason, 100 * $discon{$reason} /
$total,
$discon{$reason}, $total;
}
To use it,
cat /var/log/pm_term | /usr/local/bin/pm-term.pl
And *please* share your results with others. It would be nice to see a
baseline of some sorts by which we can all compare. Also, if you are
worried about publically posting this info, email me, and I will post it on
your behalf so there is no way to tie to information back to your company.
