Nagios Support Forum

Hi Support, I am seeing a critical error on many hosts with the description "ERROR: Description/Type table : No response from remote host". Please assist.

when I do snmpwalk from the Nagios server this is what I get

Did not find 'zeroDotZero' in module SNMPv2-SMI (/usr/share/snmp/mibs/IP-MIB.txt)
Did not find 'zeroDotZero' in module SNMPv2-SMI (/usr/share/snmp/mibs/EVENT-MIB.my)
Did not find 'zeroDotZero' in module SNMPv2-SMI (/usr/share/snmp/mibs/DISMAN-SCHEDULE-MIB.txt)
Timeout: No Response from Server1

The messages from what you ran the snmpwalk suggest that one of the MIB files is missing, corrupted or that it was mistakenly updated and the required info is missing.
To further troubleshoot this, can you run the following commands as root and post the outout to the post? Thanks
