Riseup invite code
by lists＠for-privacy.net 09 Oct '20

09 Oct '20

Hiho rise up members, I would like to receive the mails for my hosted Tor relays, such as support tickets from my provider, via Riseup. Can one of the Riseup.net users on this list send me an invite code? Right on me, not in the list ;-) mailto:admin@for-privacy.net or my lists address -- ╰_╯ Ciao Marco!

Malicious Tor relays - post-analysis after two months
by Corl3ss 07 Oct '20

07 Oct '20

Hello, This summer Nusenu shared his posts about malicious relays [1][2] and it was followed by many answers. A very important is Roger's one [3] explaining that the malicious relays have been kicked out of the network and that any new one should be reported. I was wondering if, with some distance with this summer situation / discussion : * new malicious relays have been reported in any way ? * vigilance / watchfulness is still needed ? if yes : * is there specific cases to share (e.g. nodes that block HTTPS on a site or redirect to HTTP ?) * any concern to have on other protocols that use SSL (imaps, smtps, ssh) ? * is there / will there be things implemented as a conclusion of the "call for support for proposal to limit large scale attacks" ? * has it been possible to prepare / set up precautions to avoid this king of situation or it is a too long shot for such a problem ? These questions come with a lot of respect for the project, its teams and the work done. No critics, it is just made to update the knowloedge on the subject as these questions came back with other friends and relay operators. And perhaps a last one, perhaps specific for Nusenu : how do you define a malicious relay ? Sorry but I did not get that precisely, moreover in big group analysis. All answers will be read with care and gratitude ! --- Corl3ss 2042 5D39 E7C1 E657 025E A28F 937D 8A90 FCB0 E24A [1] https://lists.torproject.org/pipermail/tor-relays/2020-July/018643.html [2] https://lists.torproject.org/pipermail/tor-relays/2020-August/018817.html [3] https://lists.torproject.org/pipermail/tor-relays/2020-August/018845.html

Exit not utilizing full bandwidth
by 4punk7＠mailbox.org 26 Sep '20

26 Sep '20

Hi, i am running a tor exit node for over 2 years now and it's just using around 1.7 MiB/s of a 100 MBit/s connection. My other relays (not exits) from the same hoster (same bandwidth) are using around 10 MiB/s (which is the rate I expect). I have tried to limit the bandwithrate, set no limits, adding IPv6 and also excluding relays from overseas (i'm located in Germany). Nothing happened. CPU is around 10%... Any idea how to speed up the exit ? Thanks, apunkt Tor Version is 0.4.2.7, here is my current torrc: /var/log/tor/notices.log RunAsDaemon 1 DataDirectory /var/lib/tor ControlPort 9051 ORPort 1234 ORPort [2a0a:51c0::103]:9001 Nickname 4punk7e1 RelayBandwidthRate 100 MBytes # Throttle traffic to 100KB/s (800Kbps) RelayBandwidthBurst 100 MBytes # But allow bursts up to 200KB (1600Kb) MyFamily $CEFBCB5FCE5FB37784AD489BCDEC46F1D59C06CB,$ABA31795BAD2AB8097F3AD0FE1A9 20E518D3D3F3 ExitRelay 1 IPv6Exit 1 ExitPolicy reject6 *:22 ExitPolicy reject6 *:587 #ExitPolicy reject6 *:* ExitPolicy accept *:20-21 # FTP #ExitPolicy accept *:22 # SSH ExitPolicy accept *:23 # Telnet ExitPolicy accept *:43 # WHOIS ExitPolicy accept *:53 # DNS ExitPolicy accept *:79 # finger ExitPolicy accept *:80-81 # HTTP ExitPolicy accept *:88 # kerberos ExitPolicy accept *:110 # POP3 ExitPolicy accept *:143 # IMAP ExitPolicy accept *:194 # IRC ExitPolicy accept *:220 # IMAP3 ExitPolicy accept *:389 # LDAP ExitPolicy accept *:443 # HTTPS ExitPolicy accept *:464 # kpasswd ExitPolicy accept *:465 # URD for SSM (more often: an alternative SUBMISSION port, see 587) ExitPolicy accept *:531 # IRC/AIM ExitPolicy accept *:543-544 # Kerberos ExitPolicy accept *:554 # RTSP ExitPolicy accept *:563 # NNTP over SSL #ExitPolicy accept *:587 # SUBMISSION (authenticated clients [MUA's like Thunderbird] send mail over STARTTLS SMTP here) ExitPolicy accept *:636 # LDAP over SSL ExitPolicy accept *:706 # SILC ExitPolicy accept *:749 # kerberos ExitPolicy accept *:853 # DNS over TLS ExitPolicy accept *:873 # rsync ExitPolicy accept *:902-904 # VMware ExitPolicy accept *:981 # Remote HTTPS management for firewall ExitPolicy accept *:989-990 # FTP over SSL ExitPolicy accept *:991 # Netnews Administration System ExitPolicy accept *:992 # TELNETS ExitPolicy accept *:993 # IMAP over SSL ExitPolicy accept *:994 # IRCS ExitPolicy accept *:995 # POP3 over SSL ExitPolicy accept *:1194 # OpenVPN ExitPolicy accept *:1220 # QT Server Admin ExitPolicy accept *:1293 # PKT-KRB-IPSec ExitPolicy accept *:1500 # VLSI License Manager ExitPolicy accept *:1533 # Sametime ExitPolicy accept *:1677 # GroupWise ExitPolicy accept *:1723 # PPTP ExitPolicy accept *:1755 # RTSP ExitPolicy accept *:1863 # MSNP ExitPolicy accept *:2082 # Infowave Mobility Server ExitPolicy accept *:2083 # Secure Radius Service (radsec) ExitPolicy accept *:2086-2087 # GNUnet, ELI ExitPolicy accept *:2095-2096 # NBX ExitPolicy accept *:2102-2104 # Zephyr ExitPolicy accept *:3128 # SQUID ExitPolicy accept *:3389 # MS WBT ExitPolicy accept *:3690 # SVN ExitPolicy accept *:4321 # RWHOIS ExitPolicy accept *:4643 # Virtuozzo ExitPolicy accept *:5050 # MMCC ExitPolicy accept *:5190 # ICQ ExitPolicy accept *:5222-5223 # XMPP, XMPP over SSL ExitPolicy accept *:5228 # Android Market ExitPolicy accept *:5900 # VNC ExitPolicy accept *:6660-6669 # IRC ExitPolicy accept *:6679 # IRC SSL ExitPolicy accept *:6697 # IRC SSL ExitPolicy accept *:8000 # iRDMI ExitPolicy accept *:8008 # HTTP alternate ExitPolicy accept *:8074 # Gadu-Gadu ExitPolicy accept *:8080 # HTTP Proxies ExitPolicy accept *:8082 # HTTPS Electrum Bitcoin port ExitPolicy accept *:8087-8088 # Simplify Media SPP Protocol, Radan HTTP ExitPolicy accept *:8232-8233 # Zcash ExitPolicy accept *:8332-8333 # Bitcoin ExitPolicy accept *:8443 # PCsync HTTPS ExitPolicy accept *:8888 # HTTP Proxies, NewsEDGE ExitPolicy accept *:9418 # git ExitPolicy accept *:9999 # distinct ExitPolicy accept *:10000 # Network Data Management Protocol ExitPolicy accept *:11371 # OpenPGP hkp (http keyserver protocol) ExitPolicy accept *:19294 # Google Voice TCP ExitPolicy accept *:19638 # Ensim control panel ExitPolicy accept *:50002 # Electrum Bitcoin SSL ExitPolicy accept *:64738 # Mumble ExitPolicy reject *:* ExcludeNodes {US},{CA}

Expiration time from torbulkexitlist
by Julien Moutinho 22 Sep '20

22 Sep '20

Hello Tor fans, New to Tor here, nonetheless this month I've tried to work on some type-checking and hardening of Tor in NixOS (see https://github.com/NixOS/nixpkgs/pull/97740 in case this interests you), hence I've tested Tor as an Exit node a few hours behind 80.67.180.251, as visible in: https://collector.torproject.org/recent/exit-lists/2020-09-22-01-02-00 > ExitNode 483F3347218DA225540D67AC3B9D48235A23DB89 > Published 2020-09-07 19:22:15 > LastStatus 2020-09-08 01:00:00 > ExitAddress 80.67.180.251 2020-09-08 01:59:25 And, if I'm not mistaken, only used it as a non Exit node since then (mostly to test a new NixOS abstraction around onion services). It's now 14 days past my Exit node test, yet that IPv4 is still listed in: https://check.torproject.org/torbulkexitlist despite https://lists.torproject.org/pipermail/tor-project/2020-March/002759.html announcing that: > This list is updated at most once every 40 minutes depending on the > number of exit relays in the network at the time, fetching it every hour > would be reasonable. A quick grep in https://collector.torproject.org/archive/exit-lists/exit-list-2020-07.tar.xz shows that in the past at least some exit nodes have been removed after one month: > $ grep LastStatus exit-list-2020-07/13/2020-07-13-18-02-00 | sort -r | tail -1 > LastStatus 2020-06-15 03:00:00 > $ grep LastStatus exit-list-2020-07/13/2020-07-13-19-02-00 | sort -r | tail -1 > LastStatus 2020-07-11 20:00:00 Am I right to assume that one month is the expiration time from torbulkexitlist? And can I do anything to trigger the removal before that delay? Thanks in advance for your answers, Julien

It may affects? How to fix this? dynamic IP = you have your relay running at home? Then things are quite different. I guess: You have a router that connects you to the Internet and your computer running Tor gets the IP/IPv6 via DHCP? Then you have to set up port forward (ORPort, DirPort) on the router and don't need iptables on the computer in the LAN. Which OS do you have exactly. Your syslog can be every GNU/Linux, *BSD or another UNIX. Be sure you have absolutely no exit traffic, add to your torrc: ExitPolicy reject *:* and advertise the directory service on some port: DirPort 80 -- ╰_╯ Ciao Marco!
