Brian Smith (aka Nuke) gave me the source and a binary of nmap for OS/2 today, however it's a basic port and not really finished. But it's definitely a good start if someone wants to work on it. URL: ftp://ftp.netlabs.org/pub/misc/nmap-2.54beta30-os2.zip Read the doc, it needs a file called nmap-services It requires libpcap from hobbes and libpcap needs IPSpy, also from Hobbes. It's some work to set it up but it works :) One header file is missing in libpcap, get that from the original source. If you want to compile it you must do this with -Zmt Flags. He successfuly compiled it with GCC 2.8.x and GCC 3.x That's it, thanks a lot Brian. If someone does some updates please let me know :-) btw: the networking card should support promiscous mode. cu Adrian Gschwend @ OS/2 Netlabs The OS/2 OpenSource Project: http://www.netlabs.org
