Upgrade from 0.8.6c to 0.8.6e --> SNMP problem

[oxy]

Hi

here is my problem :

before the upgrade everything was ok.
After cacti upgrade, i have an snmp error on the web interface.

snmpwalk and snmpget are ok via command line.

after some debug, i found that when a use in command line "php poller.php", the following error appears :

seems to be a bug : an unknown parameter is used ...

some help would be very very appreciated !!!!!

That sucks! Ok, a few things you can do.

1) Alter the lib/snmp.php and start to remove the -O options in the "cacti_snmpget" function until it starts to not throw the errors. (Please do this either way) Pleeeeassseeee post your findings.

2) Turn on php_snmp support in PHP. In *nix, I don't know quite how to do this.

3) Upgrade Net-SNMP

We really need to know what the problem is though.

Thanks,

TheWitness

[oxy]

thanks for u're reply !!

I've removed every -O [paramter] in the lib/snmp.php

it seems to be ok:)

I was wandering where i could find the cacti function using this parameter and my question was answered in u'r post !!

thanks !!

if there's some unnormal stuff i'll do my best to post it here

[rony]

You can't remove all the -O options, it may break the parsing of OID outputs..

What version of NET-SNMP are you running?

[oxy]

NET-SNMP version: 5.0.6
Web: http://www.net-snmp.org/
Email: net-snmp-coders@lists.sourceforge.net

[TheWitness]

Can you put them back in 1 at a time until it breaks and then post the option that did it.

Thanks,

TheWitness

[rony]

Easier method would be to upgrade you NET-SNMP..

Version 5.1.x should work fine.

[TheWitness]

Ok, now what do we do smarty pants...

LJ

[oxy]

ok,

as soon as i put the -O option line 76 in snmp.php i get en SNMP error.

here is the sample :

if (read_config_option("snmp_version") == "ucd-snmp") {
74 exec(read_config_option("path_snmpget") . " -v$version -t $timeout -r $retries $hostname:$port $snmp_auth $oid", $snmp_value);
75 }else {
76 exec(read_config_option("path_snmpget") . " -O QfntUe $snmp_auth -v $version -t $timeout -r $r etries $hostname:$port $oid", $snmp_value);

[TheWitness]

It's the upper case "U" that is causing the problems. Try removing it and see if snmp starts to work again.

TheWitness

[TheWitness]

Tony,

We should remove the "U", I am taking off unit's anyway in validate_results().

Larry

[rony]

I suggest you look at older code...

We put a lot of thought in those changes. We are not going to change it on a whim.

[oxy]

Great.
I put back every -O [paramter] in the lib/snmp.php & I remove every U in the [parameter]

Snmp seems to be ok !!

thanks again

ps: I'll be in touch if there's something unnormal
