Yes.
Hi Chris, This is docemented in https://trac.torproject.org/projects/tor/wiki/doc/TorFAQ#HowcanImakemyrelaya... I hope those instructions will help you. Chris Baines schreef op 2013-02-13 17:41:

I have seen those instructions, and as far as I am aware, followed them. It says that if you use the Debian package, you just set the ports in the torrc, but this causes the errors mentioned on my system.
Tor has already changed to a non-privileged user, but you are trying to bind on ports that only root is allowed to bind on. Two solutions: 1) Run tor as root (really, a bad idea) 2) Bind to other ports than 80 and 443. Since you are resuming, you are unlikely to be a stable relay/exit/bridge anyway, so you can basically choose any port you want and just use it for your own traffic only.

3) or just do not Hibernate. Use RelayBandwidthRate to limit your bandwidth utilization instead. -- With respect, Roman

3) Remap the ports outside the restricted range using your packet filter. 4) Hack the port range check out of the kernel and recompile.
No need to hack. Can set the proc entries to control that. On Feb 13, 2013 9:26 PM, "grarpamp" <grarpamp@gmail.com> wrote:

Known bug, alas: https://trac.torproject.org/projects/tor/ticket/918 See also https://trac.torproject.org/projects/tor/ticket/8195 Do you also see this warning when you start Tor? log_warn(LD_CONFIG, "You have set AccountingMax to use hibernation. You have also " "chosen a low DirPort or OrPort. This combination can make Tor stop " "working when it tries to re-attach the port after a period of " "hibernation. Please choose a different port or turn off " "hibernation unless you know this combination will work on your " "platform."); --Roger
I assume what you're experiencing is: 1 - it initially starts up and functions as expected 2 - hits the weekly accounting max and hibernates 3 - Never recovers from hibernation because of error If so then try this: That port binding is a known issue when coming out of hibernate, I also experienced it. The solution I use is setting my Accounting Max higher than my bandwidth will be able to achieve per week. Then throttle the bandwidth to a rate that I can be sure actually does not ever attain that limit, but reaches the limit I really want it to hit. If not: Check your logs and you'll discover the error there. - David On 02/13/2013 08:41 AM, Chris Baines wrote:

Hi, Run this as root: setcap 'cap_net_bind_service=+ep' /usr/sbin/tor This will give Tor the ability to bind to ports below 1024 without requiring root. On 13.02.2013 17:41, Chris Baines wrote:
