Doscan is a tool to quickly scan your network for machines listening on a
|
|
TCP port, opening thousands of TCP connections in parallel.
|
|
Features
|
|
High scanning rate: five to ten minutes per 100,000 addresses (which
|
|
are sparsely populated with hosts), with rather conservative timeouts.
|
|
Load distribution: doscan scans the addresses in a seemingly random
|
|
order. If your scan host is connected to a central router, this ensures
|
|
that the load is distributed across your network, and you are
|
|
stress-testing just a single router, and not your edge devices.
|
|
Low memory consumption: memory usage is proportional to the number
|
|
of hosts which have responded so far, and to the number of parallel
|
|
connections. The total number of addresses does not influence memory usage
|
|
in any way.
|
|
Can collect responses: doscan optionally records data which is sent
|
|
by the hosts which are being scanned. You can even specify a regular
|
|
expression to extract part of a server banner, and a message to send to
|
|
trigger a response (great for determining HTTP server versions).
|
|
Extensibility: It is possible to add special handlers for TCP-based
|
|
protocols, using a straightforward interface.
|
|
It supports scanning the vulnerable Microsoft DCOM implementation.
