Andrew,
when replying please make sure you include
snm...@li... as a recipient so everyone reading the
list can chip in or benefit.
The content you have pasted there is just the end of the
/usr/sbin/snmptthandler file (note the mismatched close curly-bracket at
the end).
I would think the relevant section you need to edit is this one:--
my $spoolfile = $spool_directory.'#snmptt-trap-'.$s_pad.$usec_pad;
unless (open SPOOL, ">$spoolfile")
{
if ($DEBUGGING >= 1)
{
print "Could not write to file file $spoolfile! Trap
will be lost!\n";
}
die "Could not write to file $spoolfile! Trap will be lost!\n";
}
print SPOOL time()."\n";
while (defined(my $line = <>))
{
print SPOOL $line;
if ($DEBUGGING >= 1)
{
# Print out item passed from snmptrapd
print $line."\n";
}
}
So I guess you could add a similar section of code beginning something like
:-
my $spoolfilebak =
/var/spool/snmptt-backup/.'#snmptt-trap-'.$s_pad.$usec_pad;
and so on..
If your perl coding skills are as bad as mine though, it might take a bit
of experimentation to get it working nicely.
Note there doesn't seem to be a line:-
close (SPOOL);
anywhere. I would add one if you're going to re-use the SPOOL filehandle.
That's probably about the limit of how much I can help you without studying
the PERL documentation, which you might as well do rather than me... ;-)
Personally I'd only hack the code like this as a last resort. Does DEBUG
really not give you what you need?
Cheers,
Jim
