The method of portscanning refered to is super basic (TCP connect), and will set off IDS's everywhere. I like nmap alot, and have used it for years to scan machines (both my own and others). nmap is written in c. Last summer (during a 2 month span of unemployment), i implemented some of the scans nmap does in perl (using Net::RawIP, which is a perl binding for libpcap). I fully implemented syn, fin, xmas, and null scans in perl. I started implementing remote OS detection via TCP (what nmap is _really_ famous for), but then stopped and got interested in Xprobe, which was remote OS detection via ICMP. Then I got a job, and stopped on both projects. I still have the portscanning code sitting around; i may get around to CPAN'ing it, although it's incredibly slow in comparison to similar code written in c.
