How to Install Nmap 7.25 beta2 on Ubuntu 16.04. Nmap (Network Mapper) is a security scanner utility for network discovery and security auditing. It performs tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap supports dozens of advanced techniques for mapping out networks filled with IP filters, firewalls, routers, and other obstacles. This includes many port scanning mechanisms (both TCP & UDP), OS detection, version detection, ping sweeps, and more. See the documentation page.
Nmap 7.25 beta2
Nmap 7.25 beta2 is the latest release. It brings various performance improvements for large-scale high-rate scanning, including increased ping host groups, faster probe matching, and ensuring data types can handle an Internet’s-worth of targets. Nmap’s parallel reverse DNS resolver is now more robust, fully handling truncated replies.
Other changes in the Nmap 7.25 beta2 are:
- Windows binaries are now code-signed with our “Insecure.Com LLC” SHA256 certificate. This should give our users extra peace-of-mind and avoid triggering Microsoft’s ever-increasing security warnings.
- Upgraded NSE to Lua 5.3, adding bitwise operators, integer data type, a utf8 library, and native binary packing and unpacking functions. Removed bit library, added bits.lua, replaced base32, base64, and bin libraries.
- Integrated all of your service/version detection fingerprints submitted from January to April (578 of them). The signature count went up 2.2% to 10760. We now detect 1122 protocols, from elasticsearch, fhem, and goldengate to ptcp, resin-watchdog, and siemens-logo.
- New, very fast IOCP Nsock engine uses “Overlapped I/O” to improve performance of version scan and NSE against many targets on Windows.
- Fix a crash when closing Zenmap due to a read-only zenmap.conf. User will be warned that config cannot be saved and that they should fix the file permissions.
- Fix a crash when parsing TLS certificates that OpenSSL doesn’t support, like DH certificates or corrupted certs. When this happens, ssl-enum-ciphers will label the ciphersuite strength as “unknown.” Reported by Bertrand Bonnefoy-Claudet.
- Long-overdue Spanish language translation has been added!
- Added a –script-timeout option for limiting run time for every individual NSE script.
- Added a -z option to Ncat. Just like the -z option in traditional netcat, it can be used to quicky check the status of a port. Port ranges are not supported.
- Fix checking of Npcap/WinPcap presence on Windows so that “nmap -A” and “nmap” with no options result in the same behaviors as on Linux (and no crashes)
