Re: exec problem with 5.1

[Mike Lipsey]

Here is the info; Sorry I didn't include it to begin with. I know better than that...

 

snmpd.conf:

rocommunity  <community>
syscontact  [EMAIL PROTECTED]
disk /boot
disk /
disk /home
disk /usr
disk /var
disk /tmp
exec .1.3.6.1.4.1.2021.51 pingscript.pl /path/pingscript.pl server1
exec .1.3.6.1.4.1.2021.52 pingscript.pl /path/pingscript.pl server2
exec .1.3.6.1.4.1.2021.53 pingscript.pl /path/pingscript.pl server3
exec .1.3.6.1.4.1.2021.54 pingscript.pl /path/pingscript.pl server4
exec .1.3.6.1.4.1.2021.55 pingscript.pl /path/pingscript.pl server5
...
exec .1.3.6.1.4.1.2021.55 pingscript.pl /path/pingscript.pl server20

Pingscript:

#!/usr/bin/perl -w
#use strict;
use POSIX qw(strftime);
@hosts = $ARGV[0];
my $hostname = `hostname -s`;
chomp $hostname;
my $timenow = strftime "%m/%d/%y-%H: %M:%S", localtime;
foreach my $host (@hosts)
{
        my @cssh = `ping -c 100 -f $host`;

        foreach my $pricegrabber (@cssh)
        {
                if($pricegrabber =~ /^(\d+) packets transmitted, (\d+) received, (\d+)% packet loss, time (\d+)ms/)
                {
                        if($1 == $2)
                        {
                                print "$hostname->$host: OK\n";
                                next;
                        } else {
                                print "$timenow $hostname->$host: sent: $1 -- recvd: $2 -- packet loss: $3% -- time: $4ms\n";
                        }
                }

        }
}#ENDOFSCRIPT

 

That's what I've got, every time I run an snmpget against the oids however  once I get to the server #4 I get the response expected and then server 5 and on times out.

If I upgrade to 5.3 and use extend however it does work and I don't have the problem but sometimes the agent does crash.

What can I do to enable debugging of the agent to syslog? I tried to rtfm but wasn't able to see it readily.

Thanks!

We'd need to know the exact details of your setup (including the ping
script itself) to be able to help. If the agent hangs, what are the last
couple of lines of "snmpd -f -Le -DALL" output?

In case this turns out to be a problem with your existing net-snmp 5.1
installation, however, upgrading is likely to be the suggested option.
