I discovered Electrum and bitcoin because it was preinstalled on Trisquel. I
use as well Trisquel for dealing with the online plattform from my local
bank. I managed to compile bitcoin-qt by myself, because I was told that it
was safer than running a lightweight wallet, and, by the way, it works fine.
I mean, I´m using Trisquel for dealing with money. So I m little concerned
about what kind of safety measures should I run to stay as safe as possible
when connected to the internet.
I m connected to the internet using a Router VG 8050 Comtrend that was
provided by my phone company. ( Optical Fiber ).
The connection was like automatic, nothing was configured neither on the
modem or computer, the technician just came to my house and... "plug and
play".
Gathering some information I learned about a firewall called UFW, that would
block incoming connections, so I suppose I should run it on to stay safer.
Little do I know about internet configuration and security but these are the
ports I need to keep opened.
Default Bitcoin network protocol listen port is 18333 (testnet) and 8333
(standard bitcoin network )
Default RPC connection port 18332 (testnet)and 8332 ( standard bitcoin
network )
I need as well the torrent client Transmission and Icedove working fine. I
don´t know if I should keep any other ports opened apart from the ports
above. Of course I need Abrowser and Midori working fine and loading all kind
of websites.
Should I block all the incoming connections running
sudo ufw enable
?. And then, unblock the desired ports with?
sudo ufw allow 18333
sudo ufw allow 8333 etc...
Is there any ports I have to keep opened for Transmission and Icedove?.
Browsers will keep on loading pages after doing this?.
Do you recommend UFW for Trisquel or is there any other firewall for this
distro?.
Should I configure something else on my router or O.S to stay as safe as
possible when connecting my computer to the internet for moneytransfer?.
What kind of things should I check from my internet connection and how?.
Thanks in advance to those who could say something back. Kind Regards!.
