Tor memory leak (0.3.5.7)?
by Roman Mamedov 23 Jun '19

23 Jun '19

Hello, As sometimes happens, I notice my nodes getting into swap heavily. This time: ------------ KiB Mem: 1010576 total, 897388 used, 113188 free, 5144 buffers KiB Swap: 1048572 total, 123592 used, 924980 free. 61732 cached Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4740 debian-+ 25 5 565448 259032 15204 R 63.2 25.6 1621:47 tor 4765 debian-+ 25 5 491636 200812 13136 S 32.9 19.9 678:36.65 tor total used free shared buffers cached Mem: 1010576 870392 140184 4 1144 64604 -/+ buffers/cache: 804644 205932 Swap: 1048572 123592 924980 ------------ After killing PID 4740 and starting that instance again (now PID 25456): ------------ KiB Mem: 1010576 total, 691264 used, 319312 free, 4336 buffers KiB Swap: 1048572 total, 58624 used, 989948 free. 209692 cached Mem Unknown command - try 'h' for help PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4765 debian-+ 25 5 491636 195900 8584 R 38.3 19.4 678:56.29 tor 25456 debian-+ 20 0 441092 240824 140452 S 29.9 23.8 0:28.48 tor total used free shared buffers cached Mem: 1010576 663816 346760 12 4344 209692 -/+ buffers/cache: 449780 560796 Swap: 1048572 58624 989948 ------------ How come killing a Tor instance which was shown to be using 259 MB of RAM, has freed up 355 MB, even counting the new copy of Tor which was started in its place and is already using 240 MB? The math only adds up to 19 MB delta, not 355. As this memory usage doesn't seem to be attributed to Tor, it reminds me of that major memory leak which was fixed some time ago, so maybe it was not fixed entirely? -- With respect, Roman

Dear List, I am running Centos7 (CentOS Linux release 7.6.1810 (Core)) and Tor v. 0.3.5.7. Now I see in nyx that is is unrecommended, but the epel repo doesn't have 0.3.5.8. Should I be adding another repo, or just wait, or try to compile my own? TIA, --Torix Sent with [ProtonMail](https://protonmail.com) Secure Email.

Wrong country and AS number/ name
by ILikeTor 20 Jun '19

20 Jun '19

Hello everybody, I have set up a relay about 3 days ago now. I am hosting my relay at a German hosting provider called "contabo", but the relay search of Tor Metrics tells me that the relay is based in the United States and that the AS number and name are unknown. Does someone know what I could do to fix this? Link: https://metrics.torproject.org/rs.html#details/53E89AD9B9320749F04DCA757F1C… Thanks in advance :) ILikeTor (or so - I definitely need a better nickname :/)

Tor Debian repo update

Hello, Does the official Tor Project repo provide upgrades to the new 0.4.0.5 stable for anyone? I can see the new packages in pool/main/t/tor/, but the package index in dists/stretch/main/binary-amd64/Packages still points to 0.3.5.8. Regards, /peter

Moving Exit Node
by Yggdrasil Admin 20 Jun '19

20 Jun '19

Hi at all. Yesterday i was kicked by my hosting provider urdn (https://urdn.com.ua) kicked me because "someone we can't name here, wasn't happy" about what i did on a non urdn server. That's why they nullrouted my ipv4 and made the Exit Node inaccessible. After a talk with the support over jabber he told my that the server was still accessible over ipv6 so i backuped my identity keys and tried to setup my exit node on another server which wasn't possible because it alway tried to connect to the nullrouted ipv4. My main question is: Can i setup my exit node on another server with another ipv4 or is this impossible? Regards

Or must I wait patiently - how long? If your relay becomes a Guard, a small number of clients will use its IPv6 ORPort. We want to use IPv6 more in tor, but we have to write the code to do it, and work out if it has any anonymity issues.

Basically, assuming relays communicate between them over ipv4, guards and exits supporting ipv6 would allow clients with ipv6-only connectivity to join the network, and establish connections to ipv6-aware servers. So I guess it makes sense if you relay ever gets the guard flag.

exit relay "internal error"
by dns1983＠riseup.net 19 Jun '19

19 Jun '19

Hello, I have an exit relay on a debian remote vm. Yesterday, after I installed the last linux security update, I rebooted It, and than I had a problem with additional IPs, that were no more being assigned. In order to understand if it were a problem caused by the last upgrade I restored a previous backup, that I made on May with tar. I didn't solved the problem restoring the backup, so I opened a ticket with my provider. Now they have fixed this issue, but my tor instance is going in loop. The log says: ...

Having trouble getting my relay to be picked up

Good evening, I am having some trouble running a tor relay node. I have forwarded TCP 9001, and can confirm I can access it from outside of my network. I used the following instructions to set up my node: https://trac.torproject.org/projects/tor/wiki/TorRelayGuide/DebianUbuntu Here is the relevant snippet from my log file: Jun 15 23:31:00 TorRelay systemd[1]: Starting Anonymizing overlay network for TCP...
