Connecting to Diffusion over port 80 instead of 8080 is a common request. This guide will work through a resolution to this problem.
You have a UNIX server and you would like your Diffusion server to be accessible over port 80 instead of 8080. This presents some problems.
- On UNIX any ports lower than 1024 are privileged. Services using these ports must be run as root.
- It is not recommended that Diffusion is run as root – therefore it cannot listen to any of the ports 80 (http) or 443 (https)
- However externally you would like Diffusion accessible over these ports.
iptables are used to re-route traffic from port 80 to 80, and port 443 to 8443 1. The following command will configure the machine to accept incoming connections to port 80.
iptables -A INPUT -i eth0 -p tcp --dport 80 -j ACCEPT
2. The following will do the same for port 8080.
iptables -A INPUT -i eth0 -p tcp --dport 8080 -j ACCEPT
3. The final command will perform the rerouting.
iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080
These steps can then be repeated for ports 443 and 8443.
iptables command is reserved for the root user. Please double check each command before submitting it as the impact for errors is high.
