I don’t know very well the linux command lines, but I finnaly find a way to run a Grin node.
However the node can only connect to 8 peers. I am wondering if there is a way to increase the number of peers to connect. Someone told me I could port forward to port 3414. But I tried several solutions and sadly no one worked.
Anyone have idea how to increase the peers connected to the node?
BTW, the system is Debian 10.
Thank you in advance!
Increase peer_min_preferred_outbound_count in your grin-server.toml config file. To get inbound connections, you’ll have to configure your router to forward port 3414 to your computer’s internal IP address (probably something like 192.168.x.x or 10.x.x.x). Google/duckduckgo your router model number and “port forwarding” and you should be able to find a guide
Appreciate your prompt reply, David!
I will try more. 
you don’t gain anything by using more peers and generally hurt the network by doing so, especially if you don’t allow incoming connections.
Thank you for your answer. I think it’s better for me not to make any changes before I learn more.
