Screenshot About:
Nmap ("Network Mapper") is a utility for network exploration, administration, and security auditing. It uses IP packets in novel ways to determine which hosts are available online (host discovery), which TCP/UDP ports are open (port scanning), and what applications and services are listening on each port (version detection). It can also identify remote host OS and device types via TCP/IP fingerprinting. Nmap offers flexible target and port specifications, decoy/stealth scanning for firewall and IDS evasion, and highly optimized timing algorithms for fast scanning.

[»] multi-threaded scanning suggestion
by Scott Edwards - Jul 7th 2004 05:37:40

At one time there was a nice little utility that scanned with two
threads. (and was very fast!) one thread would transmit, and
the other would log open ports as soon as they were
received. It used a touch of crypto to ensure it wasn't
receiving spoofs. scanning from two machines (or more)
would be a neat trick as well, as all the traffic initiators could
scan in behalf of the listener, and the listiner would log any
ports that were open matching the crypto signature.

Due to port speed scanning limitations and throttoling
requirments, you can scan one port on multiple hosts until
you've exausted all hosts, then scan for another port. This
lessens the need for throttoling.

I'd say mention my name somewhere, but I'm sure nmap has
a zillion contruibitors by now.

[»] The coolest tool for Linux!
by Gabriele - Jun 20th 2003 04:54:17

I like it very much, haven't found nothing better since now!!
A suggestion: please add a command line textbox in the GUI version,
because many options are not accessible through nmapfe.
Thanks a lot, you're the best!! :-)

    Thanks, I am glad you find Nmap useful! I agree that an explicit field for command-line arguments would be valuable. But for now, sticking them in the "Target(s)" field works fine. Newer versions of NmapFE also support a larger selection of Nmap arguments, making this less-often necessary. And of course you can always use the standard command-line version of Nmap for custom commands.

[»] good scanner
by karellen - May 2nd 2000 03:02:10

This is the best, most flexible and featured open-source port scanner currently available. Please add a --without-nmapfe option to the configure script.
