net-snmp 5.2 + openbsd 3.7 + cacti 0.8.6f --> freeze

[xtalex]

Good evening,

I have set up 2 machines with net-snmp 5.2 built from the latest stable ports.

The one with cacti 0.8.6f (built from the lastest stable ports) is a freebsd 5.4-stable, and is getting snmp information from an openbsd 3.7-stable.

Information of both machine are collecting thanks cron (/etc/crontab):

Code: Select all

*/5 * * * * cacti /usr/local/bin/php /usr/local/share/cacti/poller.php > /dev/null 2>&1

Everything is working for the freebsd (ie, localhost), but when its cacti tries to get information from the openbsd machine, its (openbsd) net-snmp daemon freezes.

I read this article http://forums.cacti.net/about8134.html, but i guess this is not the same issue.

Any ideas ? Thanks.

In my 3+ years with Cacti, it has never been the source of another hosts snmp deamon freezing. You should walk the device using net-snmp:

snmpwalk -c <your_community> -v 2c <your_openbsd_host>

Before running poller.php, i execute on my openbsd : snmpwalk -c <your_community> -v 2c <your_openbsd_host> and

Code: Select all

snmpwalk -v 2c -c public localhost system.sysUpTime.0 ucdDemoUserList.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (318) 0:00:03.18

Then after :

Code: Select all

snmpwalk -v 2c -c public localhost system.sysUpTime.0 ucdDemoUserList.0
Timeout: No Response from localhost

For each time.

Don't specify a PDU. Just do a walk of the entire tree. I suspect an agent problem none the less.

Still the same error

Code: Select all

snmpwalk -c public -v 2c localhost
Timeout: No Response from localhost

Please make a post to the Net-SNMP forum about your agent crashing. It is likely a known issue as I review the posts in that forum and agent issues can be common.

I'm having the same problem on openBSD 3.6 and 3.7. If the daemon is running non-root and started with rc.local on boot it fails. If started as root it does not. If snmpd is started after a login it works fine, even running non-root.

My snmpwalk shows it fails just before this line.

IF-MIB::ifNumber.0 = INTEGER: 6

I'm running net-snmp-5.1.2 and 5.1.2p1 from packages.

I changed my snmpd files to setgid kmem. Works now.

Interesting... I will test it.

But i am using now ucd-snmp and it is working.

Can you show me your files please ?

Thanks.
