Hello Thomas, yes, this was the issue :-) Now, i must look how i can put the collected data from my snmp-subagent (attached) to snmp-agent, I think there is only the set function not included, as Dave me telled, but i'm not a perl programer :-( Regards Stefan -Ursprüngliche Nachricht- Von: Thomas Anders [mailto:[EMAIL PROTECTED] Gesendet: Donnerstag, 5.

Hello Dave,
i have found following:
if i put this line to snmpd.conf the snmpd dosn't work anymore
(snmpwalk / snmpget becomes timeout):
perl do '/usr/lib/net-snmp/agents/mysql_agent.pl';
Wenn i start the agent (snmpd) via the '-X' argument i have the
same problem as above.
The next i have found is with the /tmp/shtest that is
configured in the snmpd.conf via this line:
exec enterprises.ucdavis.50.100.1 /bin/sh /tmp/shtest
as you can see the OID is running at
enterprises.ucdavis.50.100.1, but if i make an snmpwalk i become an
errormessage:
[EMAIL PROTECTED]:/etc/snmp# snmpwalk localhost -c
public -v2c enterprises.ucdavis.50.100.1
UCD-SNMP-MIB::ucdavis.50.100.1 = No Such Object
available on this agent at this OID
[EMAIL PROTECTED]:/etc/snmp# cat /tmp/shtest
#!/bin/sh
echo hello world
echo hi there
exit 35
with an snmpwalk at enterprises.ucdavis i find following
entries in the table:
UCD-SNMP-MIB::extIndex.1 = INTEGER: 1
UCD-SNMP-MIB::extIndex.2 = INTEGER: 2
UCD-SNMP-MIB::extNames.1 = STRING:
enterprises.ucdavis.50.100.1

UCD-SNMP-MIB::extCommand.2 = STRING: /bin/sh /tmp/shtest
UCD-SNMP-MIB::extResult.1 = INTEGER: 35
UCD-SNMP-MIB::extResult.2 = INTEGER: 35
UCD-SNMP-MIB::extOutput.1 = STRING: hello world
hi there
UCD-SNMP-MIB::extOutput.2 = STRING: hello world
hi there
UCD-SNMP-MIB::extErrFix.1 = INTEGER: noError(0)
UCD-SNMP-MIB::extErrFix.2 = INTEGER: noError(0)
UCD-SNMP-MIB::extErrFixCmd.1 = STRING:
UCD-SNMP-MIB::extErrFixCmd.2 = STRING:
It's seams that no extension is make to the table :-(
Is this right, that the subagent must start before the agent is startet
?
Like this:
/usr/lib/net-snmp/agents/mysql_agent.pl
`which snmpd` -Ls DAEMON -Lf /var/log/snmpd.log -u root
-p /var/run/snmpd.pid -X -x localhost:705 -c /etc/snmp/snmpd.conf
Sorry i have forgotten to tell you that i work on an Linux Ubuntu 6.06
Server :-)
I have attached the actual snmpd.conf.
Regards
Stefan

Hello Dave,
thx for your help :-)
This is the code for set the new Value to the OID, it's included in the
Script ;-)
if ($next ne ) {
$value = $global_status{$next}{'value'};
$request-setOID($next);
$request-setValue(ASN_OCTET_STR, $value);
The Debugging Info you will find at the attachment.

Try activating the debugging code in your subagent.
What does that show?
What are the exact commands you are trying?
I haven't looked through the whole of your code, but:
My Subagent Perlscript
-- SNIP --
#!/usr/bin/perl --
sub mysql_snmp_handler {
if ($mode == MODE_GET) {
[snip]
}
if ($mode == MODE_GETNEXT) {
[snip]
}
}
#print STDERR - finished processing\n if ($debugging);
}
This handler doesn't seem to include and code to support SET
requests - just GET and GETNEXT. So it's not too surprising
that SET requests aren't working :-)
Dave
PS: Please don't include so much in-line information.
If you've got various additional code, MIB and config files,
it's probably better to include them as attachments.
