How to run?

  • Before running the server, allocate a free port for the server and open it in the firewall.
  • Install JDK: sudo apt install openjdk-11-jdk
  • (optional) run: ldd /usr/lib/jvm/java-11-openjdk-amd64/lib/libawt_xawt.so
  • Compile the project through the command line: javac -cp ./src/ -d ./out/ ./src/main/Main.java
  • Run the server: java -cp ./out/ main.Main server 5000 (5000 is the dedicated port; you can use other ports too.)
  • To run a client: java -cp ./out/ main.Main client <server IP> <server port> <client name>
    • for example: java -cp ./out/ main.Main client 127.0.0.1 5000 John
