Frequently asked questions and troubleshooting

After compiling and starting Neuron, open page 404

Check whether the port is open

By default, Neuron opens port 7000 and executes the following command to check the status of port 7000:

$ lsof -i:7000

If there is no output, it indicates that the port number is not enabled. Execute the following command to open the port: To view firewall status:

$ firewall-cmd --state

If the returned message isnot running, you must first enable the firewall:

$ systemctl start firewalld.service

Open the specified port:

$ firewall-cmd --zone=public --add-port=7000/tcp --permanent

Restart the firewall:

$ systemctl restart firewalld.service

Reload firewall:

$ firewall-cmd --reload

Success indicates success. After completion, restart Neuron.

Check whether the IP is input correctly

The neuron access format is http://x.x.x.x:7000 Where x.x.x.x represents the gateway address where Neuron is installed. Execute the following command to view the IP address:

$ ifconfig

Check whether the address after inet under the network card matches the entered address.
