Hi Rafo,

My apologies for the late reply in your request for the code on banning tor exits into *GUARDS or middle-relays*

rm ../../etc/cron.d/updateSSHkey

echo "0 0 * * *  root wget -P /root/scriptsremote/ https://check.torproject.org/torbulkexitlist" >  ../../etc/cron.d/blacklistTORexits echo "1 1 * * *  root sed 's/^/-A ufw-before-input -s /; s/$/ -j DROP/' /root/scriptsremote/torbulkexitlist"         >> ../../etc/cron.d/blacklistTORexits echo "2 1 * * *  root sed -i '/# End required lines/r /root/scriptsremote/torbulkexitlist' /etc/ufw/before.rules" >> ../../etc/cron.d/blacklistTORexits echo "3 1 * * *  root rm /root/scriptsremote/torbulkexitlist"                             >> ../../etc/cron.d/blacklistTORexits

apt install -y fail2ban

rm ../../etc/fail2ban/jail.d/sshd.conf touch ../../etc/fail2ban/jail.d/sshd.conf echo "[sshd]"                                         > ../../etc/fail2ban/jail.d/sshd.conf echo "enabled = true"                                     >> ../../etc/fail2ban/jail.d/sshd.conf echo "port = 11218"                                     >> ../../etc/fail2ban/jail.d/sshd.conf echo "filter = sshd"                                     >> ../../etc/fail2ban/jail.d/sshd.conf echo "logpath = /var/log/auth.log" >> ../../etc/fail2ban/jail.d/sshd.conf echo "maxretry = 5"                                     >> ../../etc/fail2ban/jail.d/sshd.conf echo "bantime = 24h"                                     >> ../../etc/fail2ban/jail.d/sshd.conf echo "bantime.increment = true" >> ../../etc/fail2ban/jail.d/sshd.conf echo "bantime.factor = 24"                                >> ../../etc/fail2ban/jail.d/sshd.conf echo "bantime.maxtime = 52w" >> ../../etc/fail2ban/jail.d/sshd.conf

Here I hope this is well received,

Carlos.

Hi Rafo,

I have a pre-defined fail2ban (jail) script that does all the job of banning any tor-EXIT  -dynamically updated via cron- from attempting access when this helps.

This is meant for Debian,

the synthax could do with fedora (perhaps a few code adaptation).

let me know when this is of interest.

Carlos.

Hi, I have been running a relay for a few months now without any problems. But this week I’ve received 2 DDoS alerts from my provider (Netcup), both are ~3 gigabits. They seem to be coming from other Tor relays. I’m running an Invidious like instance on my server (which uses around 600 megabits) but I have a 2.5 gigabit port. So I configured my Tor relay to use 300-400 megabits. I’m not sure where that 3 gigabit of data comes from. I have lowered my advertised bandwidth to 100 megabits, would that be enough to prevent these kind of issues?

Kind regards, Rafo
