Accelerated depreciation of older versions?
by Nick Weaver 20 Nov '25

20 Nov '25

Was there an explicit decision made or an announcement about more rapid deprecating older server versions with the "Not recommended" flag? My test relay (tor.icsi-berkeley.org <http://tor.icsi-berkeley.org/>, I use it as my own guard on some tests) was running 0.4.8.18, and I noticed today that it had gained the "Not Recommended" flag which meant my client(s) would not connect to it as the choice of guard. I updated to 0.4.8.20 (as 0.4.8.21, although technically available, wasn't announced or linked to at the time on the Tor website). It lost the "not recommended" flag but regained it again as the current consensus now only has 0.4.8.21 and 0.4.9.3-alpha as acceptable versions. (so, well, update again)? Was this a deliberate decision or in response to a problem patched in 0.4.8.21 (and not announced as high enough severity to require immediate updating?) Is this going to be a policy going forward that relays should be updated within <12 hours of patch announcement? (also, tor26 basically likes everything BUT 0.4.8.21 because that hasn't gotten added to it, I think the Tor network might be disrupted if there is no agreement at all between the 3 authorities selecting recommended version, I think there could be a situation where there is no consensus on "recommended versions" if this isn't fixed) As of time of writing, from https://consensus-health.torproject.org/ moria1 client-versions 0.4.8.19, 0.4.8.20, 0.4.8.21, 0.4.9.3-alpha moria1 server-versions 0.4.8.20, 0.4.8.21, 0.4.9.3-alpha tor26 client-versions 0.4.8.4, 0.4.8.5, 0.4.8.6, 0.4.8.7, 0.4.8.8, 0.4.8.9, 0.4.8.10, 0.4.8.11, 0.4.8.12, 0.4.8.13, 0.4.8.14, 0.4.8.15, 0.4.8.16, 0.4.8.17, 0.4.8.18, 0.4.8.19, 0.4.9.1-alpha, 0.4.9.2-alpha, 0.4.9.3-alpha, (Strikethrough: 0.4.8.20, 0.4.8.21 ) tor26 server-versions 0.4.8.4, 0.4.8.5, 0.4.8.6, 0.4.8.7, 0.4.8.8, 0.4.8.9, 0.4.8.10, 0.4.8.11, 0.4.8.12, 0.4.8.13, 0.4.8.14, 0.4.8.15, 0.4.8.16, 0.4.8.17, 0.4.8.18, 0.4.8.19, 0.4.9.1-alpha, 0.4.9.2-alpha, 0.4.9.3-alpha, (Strikethrough: 0.4.8.21 ) gabelmoo client-versions 0.4.8.19, 0.4.8.20, 0.4.8.21, 0.4.9.3-alpha gabelmoo server-versions 0.4.8.21, 0.4.9.3-alpha consensus client-versions 0.4.8.19, 0.4.8.20, 0.4.8.21, 0.4.9.3-alpha server-versions 0.4.8.21, 0.4.9.3-alpha -Nick

Switch from relay to guard
by Too 17 Nov '25

17 Nov '25

Hi, I've been running a tor guard / middle relay from my home for some while. We have rotating IP addresses but since a lot of official websites (like governmental or banking ones) seem to block us with all of our IPs, we probably looped often enough for the information to spread. Also, we don't have that much bandwidth left for tor (in theory 4MiB/s). To avoid the blocking in the future, I want to switch to a bridge. I have a few questions regarding that: - Does it even make sense to switch to a bridge after already exposing the IP(s) for the guard / middle relay for some while? - Does it make sense to run a bridge if my IP rotates every night? - Should I shut the relay off and wait some while before starting the bridge, to get the IP(s) off blocklists first? - What kind of bridge makes the most sense in this situation? In case no bridge makes sense, I'm thinking about utilizing the server capacities for a guard / middle relay that pipes the traffic through a VPN instead; I found conflicting information on whether that's a good idea though. Thanks & kind regards Top (they/them)

Exit relays and DNS privacy
by foreststack＠dmc.chat 04 Nov '25

04 Nov '25

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hello. I run several exit relays. I'm trying to keep them in diverse locations (South Africa, Moldova, USA, and Canada so far, with none in any AS that hosts more than 1% of network bandwidth). I'm using Unbound as a local recursive DNS resolver so I don't have to trust 3rd parties with the DNS queries. But I can't run Unbound on the same IP that exit traffic goes through because some nameservers blacklist Tor, so I use a second IP. With the price of IPv4s these days, this can inflate the cost of a budget VPS by a significant percentage of its original cost. Right now, Unbound is set up with prefetching and key prefetching enabled, DNSSEC validation enabled, QNAME minimization, a large cache and negative cache, and a local copy of the root zone (RFC 8806). Would it be reasonable to dedicated a single, cheap VPS for DNS queries, and have all my other exits use it as their resolver over DoT? The way I see it, that has a few pros: * By saving on IPv4 costs, I can run more relays. * An attacker who can monitor the outgoing DNS traffic doesn't know which relay it is coming from, as all relay DNS queries are mixed. * By sharing a single cache, there will be more cache hits and less need to talk to nameservers and expose queries to them. In other words, a nameserver would only know "someone on one of forest's relays looked up this site" rather than "someone on this particular relay looked up this site". But I can see there being a few cons as well: * By sharing a single cache, "timeless timing attacks" may become worse because a single lookup will prime the cache of all of my relays. * Due to their diverse geographical nature, some exits will have sub- optimal routes to the "master" resolver, which increases latency and allows more entities to know when and how many lookups my servers are making (although not what is being looked up, because of DoT). So what should I do? Run a local recursive resolver on each exit? Set up my own upstream resolver and point all my exits to it? Try to use the ISP's resolver and hope that they configure it well? Use some privacy- friendly upstream resolver like dot.sb? Use a DNS resolver hosted by a major exit operator, as suggested by Nothing To Hide in his blog post https://nothingtohide.nl/blog/improving-dns-privacy-on-tor-exit-relays/? I would like advice on the best solution here.

Being banned?
by Brian Henderson 25 Oct '25

25 Oct '25

Hi, first time using this group so I hope I am not braking any rules. I wanted to ask others if they have noticed themselves getting blocked from certain sites (such as banks) because they are running a tor relay? I have checked my ip on various lists and it seems two rarely used lists have a ban on a group of numbers from my isp, but not my number specifically. I have been using my bank for years from this connection, now i seem to be blocked and it coincides with starting to run a tor and i2p relays. I have tried to access the site from different software but it just hangs. The bank claim they are not blocking me. Anyone else had this type of problem? Brian.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 > IPv6 is locally resolved by each relay. If this fails, probably > because some DNS servers are IPv4-only, the relays shall forward > their queries to 1-2 central DNS resolver with IPv4 addresses. That would probably be doable, but it would negate the privacy and the security benefit of running a local DNSSEC-validating recursive DNS resolver. When I run my own, I can be sure that it's using a local copy of the root zone, that it's using QNAME minimization and aggressive- NSEC, that it's up-to-date and is aggressively caching negative answers (which are very common over Tor), etc. Perhaps I could have the resolver prefer IPv6 and if the nameserver doesn't support that, it could fall back to the exit's IPv4. If the nameserver blocks Tor, *then* it could be sent up to some privacy- friendly upstream resolver. I don't know if Unbound can be configured to do that natively. It might take a small patch. > The overlap of DNS servers that are IPv4-only and block Tor relays > might be small enough to tolerate the issue or just use a friendly > public resolver for them as fallback. I don't think it would be enough to tolerate the issue. Failures to get answers from big nameservers doesn't just break a few websites. It can break an entire zone. You may find that all .hu domains that lack IPv6 will become unreachable. Using a friendly public resolver as fallback, or even falling back to a high-latency resolver on one of my other nodes, is probably preferable. > In any way, I hope you enable IPv6 on your relays (start with DNS). > Because the IPv4 shortage only gets worse over time, and enabling > IPv6 is a (partial) way out, even already today. I have IPv6 enabled on all my exits that support it. Some of them do not support IPv6, but that is the fault of budget basement datacenters running in Romania, and not my own network config. ;) Regards, forest -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEvLrj6cuOL+I/KdxYBh18rEKN1gsFAmj84v8ACgkQBh18rEKN 1gseMRAAi/g6rB/Bj84IepqIB2y+BVW4klxae7IYrSFK4YNezlpNjCp4BWZIZTlS lNL3jD6w7iJmJyxKXFmpwn+bEmv5sdin15j2LHn8486L+F72XyVmogHH5rQ7Bxn8 yITnjr8EBsfEWrLZQRmmPjfqgSXXUo2r8JDN42KdivASzFh4skrQY/N8f79/fKtL qJp5FohU+Z4BFRCkgdR4wNIpQeysp6cxm3cyOVUay/ZnWNB2yQDaoT3JKsV8JlDD nzIwLqYBiNZp/qALoVWEqdy0Ohzq1Sj6WtHZHbvlQNvOH2G2nAYwRFzcHYlrdrjz TRY91oqeFgEv0TeeXbc+rcSbPwz34mQTXy80VxhuMhNmihrwI7h6kDHWQ9FNTu6I joOZIOJWTxRNaAWLEauk2j+xSOxB3wHfuyjLtXfZjyGzHiicVzi126DKf8nqWaJX hmOnlM0pdeZwgYojG9j777pLN+K01QEK8JVvtrKvHXxVx4k0jbQ/9EcdhHG5PnNd skeCiex+8x7vnSH8/nr4l3x291gKr8vFJqIK64Whq2niAkK8xw6YrIYlvVUSD/4/ HESlYMZW7STS6f3VdnzW9fvYFU+voiQ4wCLCn5wwq/VoI1CxDYRX8QdnT+ra2ogF HgEBplSu3MNQpDAhbYRJy2FVYh9BlcdgXmYrd0yoyK14x2mrzvA= =2u/4 -----END PGP SIGNATURE-----

This would only work if all nameservers support IPv6, no? I would still need to use IPv4 for the nameservers that don't, which means continuing to pay for the extra IPv4. What I'm thinking of doing is choosing a single reliable exit in each geographic location that I run, and using it as the upstream DNS resolver for all the other relays in the region. Thus I can use one relay in the USA to serve my relay in Canada, and one relay in Moldova to serve other relays in Europe. I would only need to pay for an extra IPv4 for each geographic region, and wouldn't have to suffer from the nasty >200ms latency incurred through transoceanic cables.
