Network pipes | ||
1. Purpose
Nov 24 1999, Bisqwit spoke: I just noticed that netpipes doesn't support bidirectional pipes. So I made my own version. Now I can say in computer A that "plis 12345 -io ohjelma" and in computer B that "pcon A 12345 -io ohjelma2", and they communicate together then. My example utilization was that I can send the picture of SNES-emulator to another computer via network, and grab the keyboard input there, so get two consoles to the same game. My friend wanted to watch when I play FF6, but didn't want to sit next to my monitor, and asked if he could get the picture to his monitor. And he got it. Then he asked if he could play it from his computer at the same time as me... And now it works too. Other ways of use can everybody invent theirselves. It's really easy to make simple server software with this. For example, do "plis 79 -io finger" and then you have a finger-service. Or "plis 5555 -o 'cat signature'" and then port 5555 gives your signature. 2. ExamplesExamples:
Make a finger service:
plis 79 -ioe in.fingerd
(socket connected to in.fingerd's stdin, stdout and stderr.)
Make a server giving your signature at port 5555:
plis 5555 -o 'cat signature' </dev/null 2>/dev/null
(stdout connected to socket,
stdin & stderr redirected to /dev/null)
Make a test client for tcp connections
(recommended instead of using telnet):
pcon -f localhost 11111 -i cat -o cat
(two cats: first redirects socket to stdout,
and second redirects stdin to socket.)
Make a linebuffered test client for tcp connections:
pcon www.icon.fi 80 -i cat -o cat
Make an echo server:
plis 11111 -io cat
(the cat redirects socket to socket.)
Make a redirection server (this redirects all
incoming connections in port 1234 to remotehost
port 4123 (useful for proxying)):
plis 1234 -io 'pcon remotehost 4123 -i cat -o cat'
(the first cat is from pcon to plis,
and the second is from plis to pcon.)
Connect to an irc server and assign a bot to talk with
it (stdin, stdout), errors logged:
pcon ircserver.org 6667 -io './irc-bot' 2>errors.log
Redirect world (10.10.10.10) smtp (25) port to virus checker (192.0.0.2),
redirect intra (192.0.0.1) smtp (25) port to some other port (900):
plis -h10.10.10.10 25 -io 'pcon 192.0.0.2 25 -i cat -o cat' 2>/dev/null &
plis -h192.0.0.1 25 -io 'pcon 127.0.0.1 900 -i cat -o cat' 2>/dev/null &
