Linux FAQ

Configure the Website on Port 80

By default, the TCAdmin website user runs with a normal account, and normal users can't open ports lower than 1024. To work around this limitation, you can redirect port 80 to 8880 using iptables.

Q1. How can I configure the website to run on port 80 on Linux?

A1. To configure the TCAdmin website to run on port 80, follow these steps:

1. Open a terminal on your Linux server.

2. Use the following command to redirect incoming traffic from port 80 to port 8880 using iptables:

   iptables -A PREROUTING -t nat -p tcp --dport 80 -j REDIRECT --to-port 8880

   If your server has more than one IP, and you want to redirect on a specific IP, use this command, replacing 1.2.3.4 with your server's IP address:

   iptables -A PREROUTING -t nat -p tcp --dport 80 -d 1.2.3.4 -j REDIRECT --to-port 8880

3. After making the changes, save your iptables settings. Use one of the following commands, depending on your Linux distribution:

   For CentOS:

   service iptables save

   For Debian/Ubuntu:

   iptables-save

4. You have successfully configured the TCAdmin website to run on port 80, and incoming traffic will be redirected to port 8880.

Q2. How can I redirect port 21 to port 8821 for FTP?

A2. To redirect port 21 to port 8821 for FTP, you can use a similar iptables command:

iptables -A PREROUTING -t nat -p tcp --dport 21 -j REDIRECT --to-port 8821

This command will redirect FTP traffic from port 21 to port 8821.

Enable HTTPS for the Control Panel Website

Q3. How can I enable HTTPS for the control panel website on Linux?

A3. To enable HTTPS for the control panel website on Linux, follow these steps:

1. Open the file /home/tcadmin/Monitor/tcadmin-config for editing.

2. Add the following line to the file to specify the secure web port (e.g., 8881):

   SECURE_WEB_PORT="8881"

3. Open the necessary port in your firewall to allow HTTPS traffic. You can use a command like firewall-cmd to do this.

4. After making these changes, restart the monitor service:

   /home/tcadmin/Monitor/monitor-service restart

Now, the control panel website should be accessible over HTTPS on the specified port.

Use a Custom SSL Certificate (Linux)

Q4. How can I use a custom SSL certificate for the control panel website on Linux?

A4. To use a custom SSL certificate for the control panel website on Linux, follow these steps: Create a self signed certificate

This should allow you to use a custom SSL certificate for the control panel website.

Configure the TCAdmin Website to Run with Nginx

Q5. How can I configure the TCAdmin website to run with Nginx on Linux?

A5. To configure the TCAdmin website to run with Nginx on Linux, follow the instructions provided in the article titled Setting Up Nginx With TCAdmin

File Visibility Issues in FTP or File Manager

Q6. Some/all files are not visible in FTP or the file manager. How can I resolve this issue?

A6. By default, TCAdmin protects files with execute permissions. Only files that require execute permissions should have them. To remove execute permissions from a single file, use the following command:

chmod -x /path/to/file

To remove execute permissions for all files with a specific extension, you can use a command like this:

find /path/to/game/server/root -type f -name '*.cfg' -exec chmod -x {} \;

To fix this issue on all new game servers, update the permissions in /home/tcadmin/tcafiles/games/gamefolder.

Another option is to set the value of RestrictLinuxExe to False in the server's Override.config. If you do this, it is recommended to use the game's File System Permissions to hide important files like the startup script and main binary.

Open Game Server Ports When Service Is Created (firewalld)

Q7. How can I open game server ports when a service is created using firewalld?

A7. To open game server ports automatically when a service is created using firewalld, you can configure a global game script for the game server's after-created event. Use the following commands as an example:

firewall-cmd --zone=public --permanent --add-port=${ThisService_GamePort}/tcp
firewall-cmd --zone=public --permanent --add-port=${ThisService_GamePort}/udp
firewall-cmd --zone=public --permanent --add-port=${ThisService_QueryPort}/tcp
firewall-cmd --zone=public --permanent --add-port=${ThisService_QueryPort}/udp
firewall-cmd --zone=public --permanent --add-port=${ThisService_RConPort}/tcp
firewall-cmd --zone=public --permanent --add-port=${ThisService_RConPort}/udp
firewall-cmd --reload

These commands will add the specified ports to the firewalld configuration, making them accessible for the game server service when it is created.
