SNMP query sent to Check Point machine from an external host either hangs, or fails with "connection timed out" Technical Level
Symptoms

  • SNMP query sent to Check Point machine from an external host (e.g. using the 'snmpwalk' / 'snmpbulkwalk' commands) either hangs, or fails with "connection timed out".

  • Local SNMP query on the Check Point machine itself returns the expected output.

  • SNMP query sent to Check Point machine from another Check Point machine with 'snmpwalk' command returns the expected output.

Cause

In the specific case reported to Check Point: The version of NET-SNMP packages installed an external host is higher than the version of NET-SNMP packages installed on the Check Point machine, to which the SNMP Query is sent.


Solution

In the specific case reported to Check Point, the end customer has uninstalled the existing version of NET-SNMP packages from his external host (running on a Linux OS) and installed the same version of NET-SNMP packages that is installed on the Check Point machine.

Note: The NET-SNMP packages for an external host were downloaded from http://www.net-snmp.org/download.html

 

To check the current version of NET-SNMP package on Check Point Gaia OS / SecurePlatform OS, and on a Linux OS, run one of the following commands:

  • snmpwalk --version
  • rpm -qa | grep snmp

Examples from Check Point R77.20 Gaia OS:

[Expert@R77-20-SA:0]# rpm -qa | grep snmp
net-snmp-5.4.2.1-18.cp990170001
net-snmp-libs-5.4.2.1-18.cp990170001
net-snmp-utils-5.4.2.1-18.cp990170001
[Expert@R77-20-SA:0]#

[Expert@R77-20-SA:0]# snmpwalk --version
NET-SNMP version: 5.4.2.1
[Expert@R77-20-SA:0]#
