Does anyone here use something that performs non-blocking port checks
to obtain the status of TCP ports? I have a client who wants to
frequently check multiple ports for each system in a network of
thousands of hosts, and this amounts to many tens of thousands of
port scans per hour. They want to do this through the NetView
interface and hosted from their MLMs if possible. Ideally, the port
check would not be a full TCP connect, but something like a SYN/ACK.
The tools available for checking ports on NetView do not appear to
perform parallel port checks mainly because they appear to use
blocking socket calls.
