SNMP module not working
I installed 1.3 from SVN onto a Debian etch fresh setup using the great quick guide on the Wiki, followed by the Install.php startup wizard (MYSQL: Ver 14.12 Distrib 5.0.32 Pandora: 1.3-dev Build PS070731).
I have lots of agents working but when I try to add a remote_snmp module with a hostname or IP address and click SNMP Walk I get this error:
——–
Warning: snmprealwalk() [function.snmprealwalk]: Error in packet: (noSuchName) There is no such variable name in this MIB. in /var/www/pandora_console/godmode/agentes/configurar_agente.php on line 555Warning: snmprealwalk() [function.snmprealwalk]: This name does not exist: SNMPv2-MIB::snmpEnableAuthenTraps.0 in /var/www/pandora_console/godmode/agentes/configurar_agente.php on line 555
Cannot read from SNMP source
——–If I try to add the remote_snmp module with hostname and OID then view the agent, the Data tab shows ‘This agent doesn’t have any module’. If I run snmpwalk -Os -c public -v 1 [IPAddress] .1.3.6.1.2.1.10.94.1.1.3.1.5 from the command line on the Pandora server then I see the correct value returned. Is there a configuration file in which I need to force SNMP v1 in Pandora, or maybe specify the path to the snmp binaries? I have the following PERL modules which have SNMP in their name (installed via CPAN) in case this is useful:
Net::SNMP v5.2.0
Net::SNMP::Dispatcher v3.0.1
Net::SNMP::Message v2.0.3
Net::SNMP::MessageProcessing v2.0.1
Net::SNMP::PDU v2.1.1
Net::SNMP::Security v1.1.0
Net::SNMP::Security::Community v1.1.1
Net::SNMP::Security::USM v3.0.1
Net::SNMP::Transport v2.0.0
Net::SNMP::Transport::TCP v2.0.0
Net::SNMP::Transport::TCP6 v2.0.0
Net::SNMP::Transport::UDP v3.0.0
Net::SNMP::Transport::UDP6 v2.0.0
NetSNMP::ASN v5.0203
NetSNMP::OID v5.0203
NetSNMP::TrapReceiver v5.0203
NetSNMP::agent v5.0203
NetSNMP::agent::default_store v5.0203
NetSNMP::agent::netsnmp_request_infoPtr undef
NetSNMP::default_store v5.0203
SNMP v5.0203Any suggestions to try or where to start would be appreciated!

Many thanks for the response. I had the php5-snmp deb package installed but not php4-snmp. I installed php4-snmp too and rebooted but still get exactly the same error above, and the module is not shown when viewing the Agent. Maybe I should remove both and only install php4-snmp.. Any further suggestions would be gratefully received.

Are you making the snmpwalk on the CONSOLE that currently are giving you that error ?. Are you sure that IP that you use in console is correct and that server (system used for console) has a full SNMP utils installed.
This is a SNMP/PHP related problem, forget all issues with Perl.

If I run snmpwalk -Os -c public -v 1 [IPAddress] .1.3.6.1.2.1.10.94.1.1.3.1.5 from the command line on the Pandora server then I see the correct value returned..
Is it your pandora server the same system that pandora console ?.
Can you make a snmpwalk from console ?
Can you enter a OID manually from console and get it run from network server ?.
This is weird… snmp it’s usually easy to get working at first time.

I came back to this problem on a new build and find that the problem is probably my lack of SNMP understandng. When I ran the SNMPWALK on a long numeric OID I should have spotted that a GUAGE32 value was being returned. I had to query this value: transmission.94.1.1.3.1.4.4 to get the integer ADSL SNR value I needed! Sorry for giving you the headache!
