Ports used by HelpChat Server

Default port numbers, the service each port is for, the matching settings, and how to open them in the firewall.

1. Port list

Port	Name	Purpose	helpchatsvr.ini setting	Notes
6800	Login	User registration and login authentication	login_port
6866	Kernel	Core messaging and persistent connections	kernel_port
6888	Storage	File upload and download, sending and receiving images	storage_port
6816	HelpPost	Forum / knowledge base	helppost_port	Set to 0 to disable this service
6898	Repeater	VNC remote desktop assistance relay	repeater_port	Set to 0 to disable this service
6980	Manager	Web admin console	manager_port

2. Changing port numbers

To change a port number, edit the matching setting in config/helpchatsvr.ini. Restart the service for the change to take effect.

config/helpchatsvr.ini

[port]
login_port    = 6800
kernel_port   = 6866
storage_port  = 6888
helppost_port = 6816
repeater_port = 6898
manager_port  = 6980

3. Opening the ports in the firewall

Windows Server: add inbound rules in Windows Firewall that allow the TCP ports above.

Ubuntu / Debian

bash

sudo ufw allow 6800,6866,6888,6816,6898,6980/tcp

CentOS / Kylin

bash

sudo firewall-cmd --permanent --add-port=6800/tcp
sudo firewall-cmd --permanent --add-port=6866/tcp
sudo firewall-cmd --permanent --add-port=6888/tcp
sudo firewall-cmd --permanent --add-port=6816/tcp
sudo firewall-cmd --permanent --add-port=6898/tcp
sudo firewall-cmd --permanent --add-port=6980/tcp
sudo firewall-cmd --reload

Tip

If you do not need the forum / knowledge base, set helppost_port to 0 to disable that service. Remote desktop assistance works the same way: set repeater_port to 0 to disable it.
