Package: cacti
Version: 0.8.6f-2
Severity: important

cacti versions tested: 0.8.6e-1, 0.8.6f-2
net-snmp versions tested: 5.1.2, 5.2.1

No snmp data source can be updated with snmp 5.2.1, whereas all works
well with 5.1.2 (went back to 5.1.2 to test).

Here is an excerpt of cacti 0.8.6f-2 log with snmp 5.2.1:

07/27/2005 01:42:36 PM - PHPSVR: Poller[0] DEBUG: SERVER: cmd
07/27/2005 01:42:36 PM - PHPSVR: Poller[0] DEBUG: GETCWD: /usr/share/cacti/site

07/27/2005 01:42:36 PM - CMDPHP: Poller[0] PHP Script Server Started Properly
07/27/2005 01:42:40 PM - PHPSVR: Poller[0] ERROR: Input Expected, Script Server Terminating

I suspected SNMP when I saw a segfault when running cmd.php by hand. I
tracked it until I found it in a call to snmpget. The segfault
disappears when downgrading snmp packages to 5.1.2.

Thanks,

Hi,

this bug is fixed in both recent php4 and php5:

# php4 snmp.php

Warning: snmpget(): No response from localhost in /tmp/snmp.php on line 2

# php5 snmp.php

Warning: snmpget(): No response from localhost in /tmp/snmp.php on line 2

#

Hence closing this bug report.

Ondrej.
