Build Status 
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) Simple 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 # description: An telnet service playing an ASCII movie, Star Wars Episode 4 service telnet { disable = no socket_type = stream protocol = tcp port = 23 user = root wait = no instances = 10 log_type = FILE /var/log/asciiplayer log_on_success += PID HOST DURATION log_on_failure = HOST server = /usr/bin/python server_args = -u -OO /opt/asciiplayer/ascii_telnet_server.py -f /opt/asciiplayer/sw1.txt --stdout }
