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::extNames.2 = STRING:
enterprises.ucdavis.50.100.1
UCD-SNMP-MIB::extCommand.1 = STRING: /bin/sh /tmp/shtest
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.
Regards
Stefan

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:

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 :-)

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.
