snmpcheck v1.7

snmpcheck is a free open source utility to get information via SNMP protocols.
It works fine against Windows, Linux, Cisco, HP-UX, SunOS systems and any devices with SNMP protocol support.
It could be useful for penetration testing or systems monitoring. snmpcheck has been tested on GNU/Linux, *BSD, Windows systems and Cygwin.
snmpcheck is distributed under GPL license and based on Athena-2k script by jshaw.

Note: with the -w flag, you can detect systems with write access enabled and in some cases you could use 'SNMP SET requests' to modify information on the target agent, updating the configuration of that agent, or controlling the behaviour of the remote system.
