- Author: Erwin Hoffmann. IPv6 capabilities have been included by Felix von Leitner's IPv6 patch. The original ucspi-tcp 0.88 is by D.J. Bernstein
ucspi-tcp6 is a fork of Bernsteins' ucspi-tcp 0.88 program, which includes, among the other things, ipv6 capabilities to the original ucspi-tcp. tcpserver and tcpclient are easy-to-use command-line tools for building TCP client-server applications.

chown -R root.root net/
The new ucspi-tcp6 is patched for rblsmtpd greetdelay. We'll configure greetdelay later.
The tcpserver usage, as far as IPv4 is concerned, is similar to the original Bernstein's program.
