Nmap 4.00 Released

Posted by Zonk on from the enjoy-mapping-those-n's dept.

NoExec writes "Hot off the nmap-hackers list comes news that the Nmap Security Scanner version 4.00 has been released. Dozens of major changes since 3.50 (2 years ago) are listed in the announcement. These include a rewritten (for speed and memory efficiency) port scanning engine, ARP scanning, a brand new man page and install guide, 'l33t ASCII art, runtime interaction, massive version detection improvements, MAC address spoofing, increased Windows performance, 500 new OS detection fingerprints, completion time estimates, and much more."

    Glad they finally ditched gtk1

    I wonder what's the logic in disabling raw sockets...

    Oh! Can't you see? It's all done to protect you from the evil intarweb hackers!

    That being said, the lowest level you can use now is raw ethernet frames, and that's just what nmap does - in other words, the disabling of raw sockets is completely useless...

    It uses WinPcap to send raw ethernet frames (assuming ethernet network)

    SecurityFocus just posted an excellent interview with Fyodor about the 4.00 release. Topics include speed benchmarks, version detection improvement details, the upcoming new OS detection system, and reactions to Nessus going proprietary.

    Steve Gibson is a total bonehead. His latest moronic idea was debunked on /. just a few days ago.

    Would be nice if he signed the tarball with a pgp key.

    He did. See Verifying the integrity of Nmap downloads.

    I just tried the Windows Installer (XP, SP1) and it works like a charm with WinPCap 3.1. Everything seems to work ok, although I've only run a couple of simple scans with it, just a smoke test really.

    How did nmap work in Windows before? (Did it?)
    Under XP SP2, it didn't, even with firewall disabled.*
    with nmap4 it does.

    (* in reply to later comment about disabling windows firewall)
