A new version of NMap has been released. Nmap is used for security auditing, and the new version improves performance, stability and adds more features.
Some of the new features are:
1) Fast parallel pinging of all the hosts on a network to determine which ones are up. You can use the traditional ICMP echo request (ping), TCP ACK packet, or TCP SYN packet to probe for responses. By default it uses both ACKs & ICMP pings to maximize the chance of sneaking through packet filters. There is also a connect() version for under-privileged users. The syntax for specifying what hosts should be scanned is quite flexible.
2) Improved port scans can be used to determine what services are running. Techniques you can use include the SYN (half-open) scan, FIN, Xmas, or Null stealth scans, connect scan (does not require root), FTP bounce attack, and UDP scan. Options exist for common filter-bypassing techniques such as packet fragmentation and the ability to set the source port number (to 20 or 53, for example). It can also query a remote identd for the usernames the server is running under. You can select any (or all) port number(s) to scan, since you may want to just sweep the networks you run for 1 or 2 services recently found to be vulnerable.
3) Remote OS detection via TCP/IP fingerprinting allows you to determine what operating system release each host is running. This functionality is similar to the awesome queso program, although nmap implements many new techniques. In many cases, nmap can narrow down the OS to the kernel number or release version. A database of ~100 fingerprints for common operating system versions is included, thanks to a couple dozen beta testers who worked on the last 19 private beta releases.
4) TCP ISN sequence predictability lets you know what sequence prediction class (64K, time dependent, "true random", constant, etc.) the host falls into. A difficulty index is provided to tell you roughly how vulnerable the machine is to sequence prediction.
5) Decoy scans can be used. The idea is that for every packet sent by nmap from your address, a similar packet is sent from each of the decoy hosts you specify. This is useful due to the rising popularity of stealth port scanning detection software. If such software is used, it will generally report a dozen (or however many you choose) port scans from different addresses at the same time. It is very difficult to determine which address is doing the scanning, and which are simply innocent decoys.
