SNMP Tool Description

SNMP (Simple Network Management Protocol) is one of the most powerful and important features in NetScanTools Pro. This tool communicates using SNMP version 1 and version 2c. You can gather a wealth of detailed information about the target system assuming the target is running SNMP and you have the right community name (similar to a password). For example:
  • Listening process/daemon programs running on the target.
  • Network Interface details such as the IPv4 address(es) and MAC address, speed, MTU and more of each interface.
  • TCP, UDP, ICMP, IP protocol real time statistics.
  • The LAN manager shared resources.
  • The usernames of the Windows accounts (if LAN manager MIB is running on a Windows machine)
  • Detailed information about the type of system, model number, including operating system type, revision, system uptime and sometimes information like the names of the contact person and the computer location.

Here are some descriptions of the features:
  • [Select OID...] button. This is used to bring up a selection tree for selecting the OID (object identifier) number to use during your queries. OIDs are like indexes to a particular object of data which may be static or dynamically updated in real time. This list is built using the currently loaded OIDs.
  • Get. This feature "gets" the data associated with a particular OID.
  • Set. This feature "sets" the data associated with a particular OID to a new value. The Set dialog appears with a means to select the type of data entered and the value.
  • Walk. Since the OID numbers are organized in a directory tree structure, the walk command will allow you to view all the subitem entries and their data values for a particular parent OID.
  • Translate. There are two of these features. One is for translating from a numeric OID to a more human friendly text representation and the other reverses the procedure. This depends on the text of the MIB to be present. You can easily add your own MIBs into this program.
  • Get Status. This query requests for a number of OID entries to provide you with a quick look into the status of the target system.
  • Advanced Reports. Graphically monitor traffic on interfaces, view Arp cache, show the listening ports and show the subnets and subnet masks for a target system. You can also display a list of the currently loaded MIBs, display those MIBs in a directory tree form, and add a MIB to the list.
  • SNMP Dictionary Attack Tool - uses password guessing to recovery the password from an SNMP v1/v2c device. More information.

Windows Vista compatibility: Fully functional as of v10.42.
