snmp does not work on any device after installing cacti

[bbnl]

Hi,
I have installed cacti on a ubuntu 10.04 server, i am novice in getting to know about cacti, hence please forgive me if this is a very simple question.
I have added the device but i do get the error stating snmp error, for the same device when checked through the snmpwalk through the server is working fine. but not from the cacti, this is happening to all the devices apart from the local host,
please do help me as to where i am going wrong.

Thanks in advance

Arun

You surely double checked, whether the SNMP parameters for that cacti host are correct (community string, SNMP version, port, ...). Please know, that we used specific OIDs to test host availability. Some device do not provide that data. To verify, please post output of

Code: Select all

snmpwalk -c ... -v ... <device> system

I feared, that sysDescr would be empty. Please either fill that or use Cacti 087i with allows to switch to different SNMP checks, e.g. sysUptime instead.
