www1451859563 Posted February 5, 2013 Report Posted February 5, 2013 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 the IP address in the box above and give a range of ports to scan, if the host has firewall enabled then you can try a different type of scan in the advance mode. The recommended scan type is "connect()", however other scan types can also be useful depending on the network of the target host, a "SYNC Stealth" scan type can also prove to be useful when there's a firewall blocking the ports.http://www.ipfingerprints.com/portscan.php Quote
