⁠MapSCII Telnet Server

A ready to use Docker image to serve MapSCII⁠ over a telnet server exactly like on mapscii.me

Repository : https://github.com/benjamin-feron/mapscii-telnet-server⁠

⁠Usage

$ docker run -d -p 23:23 benjaminferon/mapscii-telnet-server
$ telnet localhost
⁠With docker-compose

docker-compose.yml :

version: "3.7"

services:
  mapscii-telnet-server:
    image: benjaminferon/mapscii-telnet-server:latest
    network_mode: host
    ports:
      - 23:23

$ docker-compose up -d
$ telnet localhost

⁠Traefik integration

As it says here⁠, in a case where the server is the first to send data on the TCP stream, it works only if both of those conditions are met :

  1. The TCP router rule is rule: HostSNI(`*`)
  2. The TCP router is the only of all (TCP or HTTP) routers listening to the corresponding entrypoint

With MAPScii, we are in this situation so we have to declare a dedicated entrypoint in Traefik static configuration :

entrypoints:
  mapscii-dedicated:
    address: :23

Network creating :

$ docker network create -d bridge telnet

Traefik docker-compose.yml :

version: "3.7"

networks:
  telnet:
    external: true
  [...]

services:
  traefik:
    image: traefik:latest
    container_name: traefik
    restart: unless-stopped
    networks:
      - telnet
      - [...]
    ports:
      - "23:23"
      - [...]
    [...]

MAPScii docker-compose.yml :

version: "3.7"

networks:
  telnet:
    external: true

services:
  mapscii-telnet-server:
    image: benjaminferon/mapscii-telnet-server:latest
    container_name: mapscii-telnet-server
    restart: unless-stopped
    networks:
      - telnet
    labels:
      traefik.enable: true
      traefik.tcp.routers.mapscii.rule: "HostSNI(`*`)"
      traefik.tcp.routers.mapscii.entrypoints: "mapscii-dedicated"

$ docker-compose up -d
$ telnet domain.ltd
