snmp on linux don' t work

[lucky]

hi @all

i installed snmpwalk and snmpget and the path in cacti is really right.

when i try to display my interfáces with snmp i get following errors:

Warning: No Response from boss in /usr/local/httpd/htdocs/cacti/include/snmp_functions.php on line 69

Warning: Variable passed to reset() is not an array or object in /usr/local/httpd/htdocs/cacti/include/snmp_functions.php on line 72

It seems that you are trying to use the snmp binaries and cacti is trying to use its (non-working) SNMP support. To force this off, open up your 'include/config.php' and make line 59 read:

Code: Select all

$config["php_snmp_support"] = false;

That should hopefully fix your problem.

hi,

okay, i don' t have any errors, but also no interfaces.

i can write donald duck for hostname and there is no error ;-(

Once you turn of php's SNMP support, you must make sure you have ucd-snmp installed. Assuming you do, make sure cacti knows the full paths to your snmpwalk and snmpget binaries under 'cacti Settings'.

Also, the current version of cacti will not work out of the box with net-snmp 5.x. To check what you are using, execute the following at the command line:

Code: Select all

snmpwalk -V

If you happen to be using net-snmp 5.x, there is a patch available on this board that can be applied to your cacti install.

hi jan,

i am still using UCD-snmp version: 4.2.5

any ideas??

[raX]

What is the 'snmpwalk Binary' path that you are using in cacti? What happens if you run this at the command line?

Let's say your snmpwalk binary path is:

Code: Select all

/usr/bin/snmpwalk

In this case, execute the following at the command line and see what happens:

Code: Select all

/usr/bin/snmpwalk localhost public .

* Make sure to replace the path to snmpwalk with the path you have in cacti
* Try using the hostname/community string you are trying to add to cacti (rather than localhost/public)

I hope we can figure something out.

okay, the path to my snmpwalk and snmpget in cacti is right

that is my printout in command line for snmpwalk localhost public:

Snmpwalk is working fine and so is snmpd. Snmpd is feeding so much information that it is overloadoing itself. Try increasing the timeout value for snmpwalk using the -t <timeout value>.
