See program output:
$ python ascii_telnet_server.py --help
Usage: ascii_telnet_server.py [options]
Options:
-h, --help show this help message and exit
--standalone Run as stand alone multi threaded TCP server (default)
--stdout Run with STDIN and STDOUT, for example in XINETD
instead of stand alone TCP server. Use with python
option '-u' for unbuffered STDIN STDOUT communication
-f FILE, --file=FILE Text file containing the ASCII movie
-i INTERFACE, --interface=INTERFACE
Bind to this interface (default '0.0.0.0', all
interfaces)
-p PORT, --port=PORT Bind to this port (default 23, Telnet)
-v, --verbose Verbose (default for TCP server)
-q, --quiet Quiet! (default for STDIN STDOUT server)
-r FPS, --framerate=FPS
Set the framerate of the movie(default 24)
-s WIDTHxHEIGHT, --size=WIDTHxHEIGHT
Set the screen size of the movie(default 80x24).
Including the timebar, so the maximum framesize is
WIDTHx(HEIGHT-1)(default maximum 80x23)
-S FRAME_WIDTHxFRAME_HEIGHT, --framesize=FRAME_WIDTHxFRAME_HEIGHT
Set the frame size(depending on the movie you are to
play) (default 67x13)
Simply call this Python script by using the sample movie file:
$> python ascii_telnet_server.py --stdout -f ./sample_movies/sw1.txt
Simply call this Python script by using the sample movie file:
$> python ascii_telnet_server.py --standalone -f ./sample_movies/sw1.txt
Running TCP server on 0.0.0.0:23
Playing movie sw1.txt
Simply build & run the container and use the movie file as environment parameter the sample movie file:
# Build image:
$> docker build -t ascii-art-movie-telnet-player .
# MODE STDOUT: Run as local player
# with the default movie
$> docker run -it --rm -e mode=stdout ascii-art-movie-telnet-player
# with a custom movie file.txt (absolute path to file it's required):
$> docker run -it --rm -v $(pwd)/your_movie.txt:/app/input_file.txt -e input_file=input_file.txt ascii-art-movie-telnet-player
# MODE STANDALONE: Run as local telnet server
# To test, open a telnet client in other terminal/session i.e. $> telnet localhost 23
# with the default movie
$> docker run -it --rm -p 23:23 -e mode=standalone ascii-art-movie-telnet-player
# Run with custon input_file.txt movie
$> docker run -it --rm -v $(pwd)/your_movie.txt:/app/input_file.txt -p 23:23 -e mode=standalone -e input_file=input_file.txt ascii-art-movie-telnet-player
place this configuration into /etc/xinetd.d/telnet:
# default: on
