to clarify... How can I redirect the output of, say, a ping scan, or even just a ping, to another tool? Can anyone show me a pseudocode or even a code example of how that is done?
I hate to be simplistic, but the easiest way to do this is simply to connect the processes via the tried and true commandline pipe. This has the downside that processes on the other side of the pipe are fully buffered (even though nmap flushes stdout every time it finishes a host, the pipe will accumulate input until a full buffer has been sent). I've successfully hooked up nmap to a custom GUI using python's popen3 function within the popen2 module with the bufsize argument set to 1 (do line buffering). I've also done some thing similar in C using popen(3) and the setvbuf(3) function calls. I unfortunately can't paste in the code (its intellectual property of a former employer); however, the info to do this is in Richard Stevens' Advanced Programming in the UNIX Environment (sections 5.4 and 14.4 have the relevant info). I'm actually in the process of writing an NMAP module in python (similar in concept to the recently posted perl module for nmap) that will be able to launch nmap invocations as well as parse the results into python accessible data structures. Its still unfinished and buggy, but when it firms up, I'll be releasing it under the GPL (and of course announcing it on the nmap mailing lists). -- William --------------------------------------------------------------------- For help using this (nmap-dev) mailing list, send a blank email to nmap-dev-help () insecure org .
