IP/Port scanner

IP and Port scanners

IP and Port scanners are frequently used to check network connectivity and website exposure to the Internet. It's a couple of tools, I've found myself in need of, quite often. Rather to carry them around, I hacked up a couple of applets, both performing a multithreaded search, attempting to create connections to various ip/ports within the target host range.

Implementation

Implemented as Applets, to be executed directly from this website. Including source packed in the .jar files

Java Port scanner

Java port scan is performed in a multithreaded application, attempting to create a socket connection to various ports on the target host name. Source is available in a downloadable jar file. May be run as a stand-alone java application as well. You may define number of threads as well as timeout used for socket-connections to ports.

It's really a quick hack and not an example to follow in how to do programming.

Java IP scanner

Java IP scan is performed in a multithreaded application, attempting to use a partial ICMP implementation in Java 1.5+ applying call to 'InetAddress.isReachable(timeoutmillis)' to perform a 'ping' to ip-addresses. Source is available in a downloadable jar file. You may define number of threads as well as timeout used for network-connections to ip's. May be run as a stand-alone java application as well.

Again... it's a quick hack and not an example to follow in how to do programming.
