ERROR: Process name table : No response from remote host

[dara79]

Hi, i seem to be getting allot of "ERROR: Process name table : No response from remote host XXX..",. lately.

doing snmp towards windows servers, some things work and some things dosent seem to be working anymore.. dont know if this is because of some windows update or some nagios update or just me doing something wrong..

doing snmpwalk -v2c -c private hostname works.. no problem..

doing ./check_snmp_win.pl -H hostname -C private --v2c -n 'ftp' dosent work anymore..

looks like all checks on processes has stopped working..


anybody have any ides on where to start checking for the problem..

ERROR: Process name table : No response from remote host XXX

Do you know which port was at the end of this message? It is most likely 161, just looking to verify.

Hi, accentually it dosent give me a port just :
ERROR: Process name table : No response from remote host '192.168.1.1'.

Its the same if i run from the console:

./check_snmp_win.pl -H 192.168.1.1 -C nagios --v2c -n 'ftp'

if i specify another port it gives a error so i believe it uses the correct one..

./check_snmp_win.pl -H 192.168.1.1:80 -C nagios --v2c -n ftp
ERROR: Inconsistent UDP/IPv4 port information specified [161 != 80].

Hmm,, i found the problem, a couple of windows 2008 R2 servers seems to have changed to only use snmp v1... for the process table.. strange..
so removing the --v2c or setting --v1 get it working again..

Ahh...very strange.. if that was on the Nagios XI server's side, you can take a look at the audit logs component if you have Enterprise edition. This will help track down when this change was made, it is located at Admin > Audit Log.
