Screenshot 154: SNMP Walk tool
To probe your network nodes and retrieve SNMP information (for example, OID’s):
1. Launch GFI LanGuard.
2. Click Utilities tab and select SNMP Walk in the left pane under Tools.
3. In the IP address menu, specify the IP address of the computer that you wish to scan for SNMP
information.
4. From Common Tasks in the left pane, click Edit SNMP Walk options or Options on the right pane
to edit the default options such as providing alternative community strings.
5. Click Retrieve to start the process.
IMPORTANT
SNMP activity is normally blocked at the router / firewall so that internet users cannot
SNMP scan your network. Malicious users can use information enumerated through SNMP
scanning to hack your network / systems. Unless this service is required, it is highly
recommended to disable it.
