Some additional info:
When I start nfsen, I see in nfsen.log:
Oct 18 23:30:06 netvis nfsen[27349]: Loading plugin 'Events': Failed.
Oct 18 23:30:06 netvis nfsen[27349]: ERROR: Events.pm did not return a
true value at /data/nfsen/libexec/Nfcomm.pm line 513.

Compilation failed in require at /data/nfsen/libexec/Nfcomm.pm line 513.
Around line 513 of /data/nfsen/libexec/Nfcomm.pm we see:
# cat -n /data/nfsen/libexec/Nfcomm.pm | sed -n '505,520p'
505
506 sub load_module {
507 my $module = shift;
508
509 my ($HasRun, $HasAlertCondition, $HasAlertAction) = (0, 0, 0);
510
511 eval {
512 local $SIG{'__DIE__'} = 'DEFAULT';
513 require "$module.pm";
514 };
515
516 if ( my $err = $@ ) {
517 syslog('err', "Loading plugin '$module': Failed.");
518 syslog('err', "ERROR: $err");
519 return ($HasRun, $HasAlertCondition, $HasAlertAction);
520 }
Is there something wrong with Nfcomm.pm or with Events.pm,
Events_mail.pm, Botnets.pm? I realize that these plugins are a bit old.
Here is: # ls -la /data/nfsen/plugins/
total 76
drwxr-xr-x 2 nfsen nfsenadmin 4096 Oct 17 11:25 .
drwxr-xr-x 11 nfsen nfsenadmin 4096 Apr 24 21:54 ..
-rw-r--r-- 1 root nfsenadmin 5477 Sep 29 2008 Botnets.pm

-rw-r--r-- 1 root nfsenadmin 13692 Apr 24 22:03 smily.jpg
Please advise how I should pursue a resolution.

Nick
