Node Operators FAQ

Thank you for the informations.

I searched from a lot of online documents on how to configure a firewall for a storj node but i didn’t find nothing, is there a port list or something else ?

When i launch docker et close my ssh session is, Docker still runing on background ?

Thanks by advance

Make an inbound rule to allow any traffic from the any source to the TCP 28967 port and your PC with a Docker as a destination.
If you have any restriction rule for outbound, then make an outbound rule to allow any traffic from any port of your PC to the any host with any port as a destination.

Hi im still confuse, i use ufw, but i got stil some UFW block 28967 in my ufw.log ?

Is there a kind of config generator or something ?

This is a general Linux question for sure.
The command to allow the TCP 28967 is sudo ufw allow 28967/tcp
To allow the outgoing traffic: sudo ufw allow from 64.63.62.61, where 64.63.62.61 is your local IP
