I personally experienced slow downs and problems using ja-netfilter agent
i decided to inspect how jetbrains check for validity of licenses(because despite the fact i exclusivly told jetbrains to work-offline it still check the licesnse)
these are my conlusions: two domains are responsible for revoking invalid licenses:
- www.jetbrains.com
- account.jetbrains.com
you can either block them in your router or locally with these iptable commands
sudo iptables -I OUTPUT -p udp --dport 53 -m string --hex-string "|03|www|09|jetbrains|03|com|" --algo bm -j DROP
sudo iptables -I OUTPUT -p udp --dport 53 -m string --hex-string "|07|account|09|jetbrains|03|com|" --algo bm -j DROP
sudo ip6tables -I OUTPUT -p udp --dport 53 -m string --hex-string "|03|www|09|jetbrains|03|com|" --algo bm -j DROP
sudo ip6tables -I OUTPUT -p udp --dport 53 -m string --hex-string "|07|account|09|jetbrains|03|com|" --algo bm -j DROP
Warning
iptables will reset on reboot unless you make it persistent
to make iptable persistent on ubuntu (after running above iptable commands):
sudo apt install iptables-persistent
sudo iptables-save | sudo tee /etc/iptables/rules.v4 > /dev/null
sudo ip6tables-save | sudo tee /etc/iptables/rules.v6 > /dev/null
when i edited /etc/hosts jetbrains started to refuse the 127.0.0.1 as the validity server and started sending out udp requests to well known dns provides:
- 8.8.8.8
- 1.1.1.1
- 1.0.0.1
- 8.8.4.4
- 9.9.9.9
i was not expecting that so i decided to complettly ban inteiilj from being resolved on my system from any source,
for now you can use this license key with above config
