2ping

2ping is an open source command-line software, written in Perl, that enables users to ping hosts on the Internet. It uses 3-way pings: SYN/ACK, TCP SYN and ACK.

In order to determine the direction of packet loss, 2ping uses after-the-fact state comparison between a 2ping client and a 2ping listener.

What is new in this release:

• Updated to support 2ping protocol 2.0:
• Protocol 1.0 and 2.0 are backwards and forwards compatible with each other
• Added support for extended segments
• Added extended segment support for program version and notice text
• Changed default minimum packet size from 64 to 128 bytes
• Added peer reply packet size matching support, turned on by default
• Added extra error output for socket errors (such as hostname not found)
• Added extra version support for downstream distributions
• Removed generation of 2ping6 symlinks at "make all" time (symlinks are still generated during "make install" in the destination tree)

Requirements:

• Perl
