Did not know that about port 22. I used a variant of the ReducedExitPolicy which accepts port 22 according to https://gitlab.torproject.org/legacy/trac/-/wikis/doc/ReducedExitPolicy . > Did you check > https://gitlab.torproject.org/tpo/core/tor/-/issues/ for the bug you > reported? I wasn't even sure if it was a bug, if I did something wrong, or if it was related to my ISP; hence my question on the mailing list. ___ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays

Yeah, those things are the spices in our dish. Not sure yet if this is an attack. I observe it too and investigate on my end.

[tor-relays] Relay not connecting
I manage the two following exit relays: * https://metrics.torproject.org/rs.html#details/25FC41154DCB2CAE3ABD74A8DFCD5B90D2CFFD57 * https://metrics.torproject.org/rs.html#details/3B85067588C3F017D5CCF7D8F65B5881B7D4C97C They are both on the same IP and servers. A few hours ago they lost contact even though I have both Apache and I2P servers on the same machine that are reachable. The weird log messages seem to go back to Dec 18, after a restart: ``` Dec 18 07:49:47 a-n-o-n-y-m-e Tor-Alberta[904715]: Bootstrapped 100% (done): Done Dec 18 07:54:18 a-n-o-n-y-m-e Tor-Alberta[904715]: Your computer is too slow to handle this many circuit creation requests!

[14254 similar message(s) suppressed in last 180 seconds] ``` There are a few more of these messages appearing afterward (My bandwidth is unlimited). This is the typical Heartbeat that comes afterward: ``` Dec 18 13:49:42 a-n-o-n-y-m-e Tor-Alberta[904715]: Heartbeat: Tor's uptime is 6:00 hours, with 476 circuits open.
