Having build my Ubuntu Pc and loaded TOR, it is now running very nicely as a Node. This is within my home network. The Node has got an IP static address, so it won't fail to get back as a Node if I have for any reason to shut it down. I intend to have the power supply via APC, so if I get a power outage the Tor server will not be affected. Like wise the ISP Hub so its always on the NET. I do have virus protection AVG on my main PC with the Firewall attachments. I will not be using the TOR relay for anything else , no email, no IRC etc. The question - Does my TOR Relay need a separate firewall and or Virus protection. If so what is recommended please.
Thank you for this,when your trying to understand a new system without anyone to talk to. I will keep persevering.
Have followed your instructions and find that ufw is already installed and running.
I then ran the 'sudo apt install unattended-upgrades' it told me that the unattended-upgrades is already the newest version and that i could use the 'sudo apt autoremove' to remove some items that are no longer required. all done and uptodate , thanks again
