Product updates
This section lists the changes implemented for Radar Discovery Scan.
Version 65249, released December 12, 2019
- [RADAR-15563] – Host discovery mode passes incorrect options to nmap.
This issue caused Host Discovery mode to miss hosts that responded only to ICMP ping and didn’t have open TCP ports.
Version 63339, released September 3, 2019
- Now using nmap 7.80
Version 61029, released February 6, 2019
- Now using nmap 7.70
Version 59770, released September 25, 2018
New features and improvements:
- With “Host Discovery” mode we used to send an ICMP ping along with the TCP SYN scan on port 80. Now we also perform a TCP SYN scan on two additional ports: 22 (Telnet) and 3389 (Remote Desktop). These are two popular open ports, so this change significantly increases the chances of discovering a host, while still maintaining high speed for the “Host Discovery” mode.
Version 57142, released February 15, 2018
New features and improvements:
- Replaced old scanning engine with Nmap to reduce scan times and improve reliability.
Fixed issues:
- Numerous issues caused by the old engine.
