multiwalk2c is a multi-threaded SNMP scanner. It
is a modified version of snmpbulkwalk. It can scan
agents listed in special agents file, write to a
single or many output files, and traverse
different parts of a MIB tree in one thread.
Information regarding Project Releases and Project Resources. Note that the information here is a quote from Freecode.com page, and the downloads themselves may not be hosted on OSDN.
A race condition could occur when the main thread tried to join created threads. Now multiwalk threads detach themselves, so the main thread is only waiting for them.
Soft stack size was limited to 512kb to avoid
consuming the whole address space when a lot of
threads are created. A switch to manually set soft
stack rlimit was added.
A parameter to set repeaters and nonrepeaters
variables was added. The maximum agents limits are
now set as a minimum of the maximum number of
opened threads and the maximum number of opened
files.
