++There is no
++.Fl c
++or
++.Fl e
++option in this netcat, but you still can execute a command after connection
++being established by redirecting file descriptors. Be cautious here because
++opening a port and let anyone connected execute arbitrary command on your
++site is DANGEROUS. If you really need to do this, here is an example:
++.Pp
++On
++.Sq server
++side:
++.Pp
++.Dl $ rm -f /tmp/f; mkfifo /tmp/f
++.Dl $ cat /tmp/f | /bin/sh -i 2>&1 | nc -l 127.0.0.1 1234 > /tmp/f
++.Pp
++On
++.Sq client
++side:
++.Pp
++.Dl $ nc host.example.com 1234
++.Dl $ (shell prompt from host.example.com)
++.Pp
++By doing this, you create a fifo at /tmp/f and make nc listen at port 1234
++of address 127.0.0.1 on
++.Sq server
++side, when a
++.Sq client
++establishes a connection successfully to that port, /bin/sh gets executed
++on
++.Sq server
++side and the shell prompt is given to
++.Sq client
++side.
++.Pp
++When connection is terminated,
++.Nm
++quits as well. Use
++.Fl k
++if you want it keep listening, but if the command quits this option won't
++restart it or keep
++.Nm
++running. Also don't forget to remove the file descriptor once you don't need
++it anymore:
++.Pp
++.Dl $ rm -f /tmp/f
++.Pp

+ The example in the previous section can be expanded to build a
+ basic data transfer model.
