DESCRIPTION hping6 is a network tool able to send custom ICMP/UDP/TCP packets and to display target replies like ping do with ICMP replies. hping6 handle fragmentation, arbitrary packet body and size and can be used in order to transfer files under supported protocols. Using hping6 you are able at least to perform the following jobs: - Test firewall rules - [spoofed] port scanning - Test net performance using differents protocols, packet size, TOS (type of service) and fragmentation. - Path MTU discovery - Files trasfering even between really fascist firewall rules. - Traceroute like under different protocols. - Firewalk like usage. - Remote OS fingerprint. - TCP/IP stack auditing. - IPv6 support - A lot of others. It's also really a good didactic tool to learn TCP/IP. hping6 is developed and manteined by antirez@invece.org and comes under GPL version 2 of license. Developing is open so you can send me patches/suggestions/affronts without inhibitions.
