Should I host my own instance if I don't intend to run a community? (lemmy.world)

I'm not super familiar with Linux, I've installed it on machines in the past, I know some very basic command line stuff. I've done raspberry pi stuff. I have a mini PC running Ubuntu right now that I am not using for anything so I can use that to run ansible. I probably won't be able to work on it until after this weekend but once I get an moment to set down and do it I will shoot you a message if I have any questions. I really appreciate your help and I am excited to be a part of the fediverse.

that would be perfect.

WIth Debian I would install UFW for a firewall. Set SSH to whatever your home IP is. You can always use the Linode SSH console for external access.

UFW is easy to configure and just translates iptables.

sudo ufw allow from any to any port 80 proto tcp
sudo ufw allow from any to any port 443 proto tcp
sudo ufw allow from HOMEIP to any port 22 tcp

If you want leave SSH open. Then i would probably only do Key based auth in /etc/ssh/sshd_config

you also want to edit that file (sshd_config) to disable root access once setup. I often turn on the following

LoginGraceTime 2m
PermitRootLogin no
StrictModes yes
MaxAuthTries 6
MaxSessions 10
AllowGroups somegroupname

then create a user and a group and add the user to the group. This ensures only that user has SSH access.

sudo adduser someusername
sudo addgroup somegroupname 
sudo usermod -aG somegroupname someusername

You can also use visudo to edit sudoers. The first like will require a password. If you use the second line, you can sudo without a password. I would only do the latter if you only use key-based auth though.


someuser   ALL=(ALL:ALL) ALL
someuser ALL=(ALL) NOPASSWD: ALL

I also edit /etc/hostname to my server name. Update and reboot. From there run through ansible instructions and make edits as necessary.
