Your program receives environment variables showing the local and remote host names, IP addresses, and port numbers. tcpclient makes a TCP connection and runs a program of your choice. It sets up the same environment variables as tcpserver. == Comments == == Usage information == == Categories == CategoryApps, CategoryAppssysutils == Source of information == http://www.bieringer.de/linux/IPv6/status/IPv6+Linux-status-apps.html
