Before last fall, a minimum of 96 or 97 hours of uptime was the only requirements for a relay to be assigned the HSDir flag, but that is clearly not all that is necessary now. Scott Bennett, Comm.

Pro-active note: The bridge shares the same 23.129.64.0/24 subnet as Emerald Onion's Tor exit relays, so there is no risk of a user entering and exiting our physical network (see "2.2.

Tor project helping to attempt to cancel Richard Stallman
by Jeffrey Cliff 26 Mar '21

26 Mar '21

I've been running a relay/exit node for many years. Tor user since ~2004. To the extent that my voice means anything at all here, I would like to strongly condemn the Tor project joining the attempt to cancel Richard Stallman. Stallman represents software freedom to me generally and as of today I will be shutting down my exit node in protest of this action by the Tor Project. I hope the rest of you out there, who depend every day on GNU project code which would not exist without RMS's project, might consider joining me. Jeff Cliff former tor exit node admin

Active MetricsPort logs "Address already in use"
by Alexander Dietrich 25 Mar '21

25 Mar '21

Hello, when I activate the "MetricsPort" feature, the Tor log reports that it is going to open the port, then it says "Address already in use". According to "netstat", the address is indeed in use, but by "tor". Sending GET requests to the address returns empty responses. Any ideas? Kind regards, Alexander -- PGP Key: https://dietrich.cx/pgp | 0x52FA4EE1722D54EB

Tor 0.4.5.6 and missing IPv6
by Marco Predicatori 25 Mar '21

25 Mar '21

Hi, I've recently upgraded to Tor 0.4.5.6. Everything seems to work fine, but in the notices_log file I have a lot of these lines: [notice] Unable to find IPv6 address for ORPort 9001. You might want to specify IPv6Only to it or set an explicit address or set Address. I don't have IPv6, and any line mentioning IPv6 in the torrc file is commented. Is there anythng I need to do in order to get rid of those notices, or can I just let them be? Thanks, Marco -- https://metrics.torproject.org/rs.html#details/A4E74410D83705EEFF24BC265DE2…

Security advisory: Please upgrade to today's OpenSSL.
by Nick Mathewson 25 Mar '21

25 Mar '21

Hi, all! There is a new version of OpenSSL out today, with a security advisory that affects Tor. The vulnerability is CVE-2021-3449, as described on https://www.openssl.org/news/secadv/20210325.txt . It affects OpenSSL versions 1.1.1 through 1.1.1j. OpenSSL 1.1.1k is the first version with a fix. I haven't tested this bug, but I believe that it would allow an adversary to remotely crash Tor relays and authorities. It won't have any effect on Tor clients. I suggest that everybody should upgrade to the latest OpenSSL when it becomes available on their platform. best wishes, -- Nick

Circuit Creation Madness: Anyone else still experiencing (extremely) excessive clients / (possibly) modified relays creating millions upon millions of circuits?
by William Kane 23 Mar '21

23 Mar '21

@tor-relays: Sorry for being quite noisy recently but I really need to know how many people are suffering from the same madness I am encountering right now. Quick excerpt from the log: ... Mar 22 09:48:10 <hostname_redacted> tor[pid_redacted]: Mar 22 09:48:10.000 [warn] Your computer is too slow to handle this many circuit creation requests!

Please consider using the MaxAdvertisedBandwidth config option or choosing a more restricted exit policy. [241332 similar message(s) suppressed in last 60 seconds] ... This then goes on for a while, stopping at a few million suppressed messages / circuit creation attempts. Sorry, but 1 million circuit creation requests in just 5 minutes, there is no way that this is legitimate behavior we are seeing - this is also what was previously used to get my relay oom-killed but that I have fixed so the legitimate clients hopefully don't suffer too much anymore. If any other relay operators are encountering the same log entries or behavior, please don't hesitate to reply. Added tor-dev(a)lists.torproject.org as a CC as they might want to know about this. @tor-dev: I suspect some kind of denial-of-service attack against onion services or a more targeted attack against singular relays for guard discovery / traffic confirmation attacks. Might be smart to add some code which, if this scenario is triggered, lists offenders by hashes of their signing keys (if relay), or IP addresses (if client). There doesn't seem to be a defense against this, and the new connect() rate-limit added through ticket 40253 also won't handle this as the connection is already ACK'd and established, and a malicious relay with custom source code could do whatever it was programmed to do anyway. - William
