New operator

Hello everyone, I have some newbie questions and I hope this is the right place to ask them. I started operating a relay on my VPS for a bit more than a month and everything seems to be going well. I constantly have about 200 outbound and 2000 inbound connections, but in nyx I almost never see any circuits. What does it mean? Do I see circuits only when someone is actually using my relay, i.e. in Tor Browser? To further support the project I decided to run a bridge at home using a Raspberry Pi. How do I know when it is being used? I rarely see any traffic. Sometimes I see one outbound connection in nyx and some circuits open, but I never see an inbound connection to port 80 (the obfs4 port I chose). Why does the bridge have open circuits more often than the relay? I couldn’t find any answers online, so I hope to clear things out here. Regards, m. _____________________________________________________________ GPG fingerprint: 6C3B 0069 30C4 0F16 E5F6 690E 7D2E 100E C3C4 7105 <https://keys.openpgp.org/vks/v1/by-fingerprint/6C3B006930C40F16E5F6690E7D2E…>

Strange OpenPGP behavior during key import under Debian Buster
by Olaf Grimm 17 Nov '19

17 Nov '19

Hello! I repeatedly try to install Tor under Debian Buster and fail again at key import. With the last system I found the solution by activating the "Experimental repos" under Debian. This time it didn't work and I kept looking. Before repair: ... 2019-11-15 21:18:33 (294 KB/s) - ‘A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89.asc’ saved [19665/19665] gpg: no valid OpenPGP data found. gpg: Total number processed: 0 My procedure: I opened the key copied from the Tor website and found at the end of the key the spelling ... sGsEejVHxvX7/iOE3rM= =47bK -----END PGP PUBLIC KEY BLOCK----- I changed the last line intuitively with an editor to ... sGsEejVHxvX7/iOE3rM==47bK -----END PGP PUBLIC KEY BLOCK----- and saved it. Afterwards the import worked! gpg2 --import ./A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89.asc gpg: key EE8CBC9E886DDD89: 36 signatures not checked due to missing keys gpg: key EE8CBC9E886DDD89: public key "deb.torproject.org archive signing key" imported gpg: Total number processed: 1 gpg: imported: 1 gpg: no ultimately trusted keys found gpg2 --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | apt-key add - OK I have no explanation!

Migrating to CentOS8
by Totor be 08 Nov '19

08 Nov '19

Hi folks I'm considering migrating my relays from CentOS 7 to CentOS 8 and upgrading tor from 0.3.5.8 to 0.4.1.6 One small VM relay at home is running the C8/0.4 setup and seems to be ok According to bodhi, this is supposed to be stable https://bodhi.fedoraproject.org/updates/?packages=tor Before migrating the others, I prefer to cross-check: is there anyone aware of issues with C8 and tor 0.4.x??

"large number of connections to other relays" - What should I do?
by Akarin 08 Nov '19

08 Nov '19

Hi I'm running a new non-exit relay on my server which has a shared address, and I often see the following message in my log file: Your relay has a very large number of connections to other relays. Is your outbound address the same as your relay address? Do I have to worry about that? If the answer is yes, what should I do?

Tor stop / reboot by itself + weird logs (hacking?)
by David Strappazon 07 Nov '19

07 Nov '19

Hello everyone, i'm running a bridge on a raspberry Pi 3B+ on Kali Linux. Everything looks fine but after checking the logs i noticed that the service rebooted by itself in the middle on the night: Nov 06 03:51:09.000 [notice] Interrupt: we have stopped accepting new connections, and will shut down in 30 seconds. Interrupt again to exit now. Nov 06 03:51:10.000 [notice] Delaying directory fetches: We are hibernating or shutting down. Nov 06 03:51:39.000 [notice] Clean shutdown finished. Exiting. etc... Then after that, it works again (will check tonight /tomorrow if it reboots again). I'm trying to find why it is rebooting but without success. I checked all logs possible and also notice this in journalctl -xe: nov. 06 19:37:58 kali-pi sshd[15920]: Failed password for root from XXXXX port 37494 ssh2 nov. 06 19:38:03 kali-pi sshd[15920]: Failed password for root from XXXX port 37494 ssh2 nov. 06 19:38:08 kali-pi sshd[15920]: Failed password for root from XXXXX port 37494 ssh2 nov. 06 19:38:13 kali-pi sshd[15920]: Failed password for root from XXXXX port 37494 ssh2 nov. 06 19:38:18 kali-pi sshd[15920]: Failed password for root from XXXXX port 37494 ssh2 nov. 06 19:38:18 kali-pi sshd[15920]: error: maximum authentication attempts exceeded for root from 21> nov. 06 19:38:18 kali-pi sshd[15920]: Disconnecting authenticating user root 2XXXX port 37494: > nov. 06 19:38:18 kali-pi sshd[15920]: PAM 5 more authentication failures; logname= uid=0 euid=0 tty=ss> nov. 06 19:38:18 kali-pi sshd[15920]: PAM service(sshd) ignoring max retries; 6 > 3 nov. 06 19:38:21 kali-pi sshd[15950]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid> nov. 06 19:38:22 kali-pi sshd[15953]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid> nov. 06 19:38:23 kali-pi sshd[15950]: Failed password for root from XXXX port 64786 ssh2 nov. 06 19:38:23 kali-pi sshd[15953]: Failed password for root from XXXXX port 6739 ssh2 There's two different IP that i don't know.

Minimum traffic for a relay to be helpful to the network
by Keifer Bly 05 Nov '19

05 Nov '19

Hello list, So a while back, I was attempting to run a relay via Google Cloud, but had trouble finding an appropriate speed without having to spend a huge amount of money on outbound traffic. I am wondering what would be a good amount to dedicate to the relay while keeping it inexpensive to run: Here is Google Clouds pricing plans https://cloud.google.com/network-tiers/pricing It appears they charge a few cents a gigabyte, thx. --Keifer
