Hi together,
I have setup an ubuntu server (18 LTS) in combination with erpnext v13-beta4 in production mode (will be used as QA instance). I am struggling with setting up the ufw firewall properly.
I have already opened the following ports (ssh, webserver, email): 22,25,143,80,443,587,995,993
Within sites/common_site_config.json the following is set (per default)
…
“redis_cache”: “redis://localhost:13000”,
“redis_queue”: “redis://localhost:11000”,
“redis_socketio”: “redis://localhost:12000”,
“socketio_port”: 9000,
“webserver_port”: 8000
Is it relevant to open the mentioned ports or is this more like internal communication and for this reason, it is fine to keep them closed?
