No, it's generally not safe from abuse complaints. Most IRC admins, who
dislike Tor, have long blocked Tor relays from their servers. Your exit
node is also usable for probing open ports on the limited number of
ports that you allow exit traffic to, which could trigger some automated
abuse detection systems.

I doubt your provider will receive a complaint anytime soon, but there
is no guarantee if that was what you hoped to receive.

If you want to continue running an IRC-only exit node, it would be
helpful if you considered adding port 6697 and , which are both
common IRC-over-TLS ports. Hopefully, nobody will connect via an exit
node to clear text IRC ports :-)

All the best,
Alex.

[tor-relays] Is running an irc only exit relay safe from abuse

[Keifer Bly]

Hi all, So my relay at https://metrics.torproject.org/rs.html#details/99929040054EC1EF0927467E4588A37879891C9C is configured for IRC only exit, I wanted to ask, is this generally safer from abuse complaints? It is running on OVH, so want to be safe. Thanks. Sent from Mail for Windows 10

as I wrote earlier, they are disconnected arbitrarily for 3-4 hours and then restored themselves, maybe it is better to remove the ports of dir? bandwidth should be enough running on four cores with 4 GB of memory speed 800/800 Mbps 14.05.2020, 22:52, "Felix" :Hi СтаниславYou have two relays running at the same IP.

May-be there are indications:

Port 80 is your DIR port.

If you suffer under potential overload or not enough resources (by what
ever reason) you can reduce.

Run only one relay with OR port only and strict DOS settings. Then wait
a week if everything works. Wait an other week. If still everything is
running well add the DIR port again and wait and wait. Add the second
relay in the same way and finally relax DOS settings.

When ever the relay(s) become unstable go one step back.

This is a recommendation but there might better ways to go.

Good luck!
