Scanning other network assets

Technology

Many network assets cannot be scanned using SMB, RPC, or SSH. These include assets that do not run Windows or Unix-based operating systems, run unsupported operating systems, or run lightweight Unix-based systems without an SSH interface. These could include network printers, managed switches, routers, xDSL modems, IP phones, wireless access points, etc. Most of these devices support SNMP and can therefore be scanned by TNI.

Scanning SNMP devices

TNI considers devices that cannot be scanned using other protocols as potentially SNMP-compatible. If enabled in the Scanner settings, TNI attempts to scan these devices using SNMP. By default, if Common communities is specified, TNI tries several well-known community strings until one succeeds:

  • admin
  • cisco
  • mngt
  • private
  • public
  • guest
  • snmpd

TNI also allows you to collect all available information about a device using the snmpwalk command. To do this, select “Enable full SNMP scan” in the SNMP settings.
