\"listening\" sockets, named pipes, and pseudo terminals.

to UNIX sockets, IPv6 relay, for redirecting TCP oriented programs to a serial
line, to logically connect serial lines on different computers, or to
establish a relatively secure environment (su and chroot) for running client

the ICMP router discovery protocol.
@item @command{tftpd}: Trivial file transfer protocol server.
@item @command{tracepath}: Trace network path to an IPv4 or IPv6 address and
discover MTU along the way.
