Network Port Scanner Tool

Description
Port scanner tool can be used to identify available services running on a server, it uses raw IP packets to find out what ports are open on a server or what OS (Operating System) is running or to check if a server has firewall enabled etc. The service can also detect uptime of a host if the host is running one of the known OSes which the scanner can analyze to guess uptime.

To scan a host just enter the host name or IP address in the box above and give a range of ports to scan (MAX: 65535), if the host has firewall enabled then you can try a different type of scan in advance mode (e.g. SYN Stealth) which can by pass the firewall in most cases. A scan other than "connect()" might take some time to finish but will give you more information about the host OS in case if a firewall is enabled on the host.
