Hey,

the easiest solution that comes to mind is a cronjob/systemd timer/whatever that modifies the config file and sends a SIGHUP to tor to trigger a config reload.

I'm not very familiar with the codebase, so I can't guarantee that reloading the config file applies new (Relay)BandwithRate settings, but from the glances I took at the code it does seem like it should do it. Please someone verify or falsify this claim.

Reloading the config file changes all the settings. For the few settings where it doesn't, tor will warn you, or refuse to reload the config.

Hi All,

this is my first post on this list so warm welcome to every one a specialy to Tor developers.

On my servers I`m running paralllel prod servers with tor relays on the separate IP. I`m supporting tor network for free with high speed tor relays but I need to customize the time when my server will share 100% of its resources for tor and when traffic will be limited.

Is it possible to schedule the time when bandwith will looks as follow:

8:00 - 18:00 - Tor relay bandwith 250kb/s

18:00 - 8:00 - Tor relay bandwith 10 000kb/s

How may I schedule this in tor relay ? Is it possible to limit traffic on the client or I need to do it on my firewall ?

Thanks in advance for any feedback.

I do see 3 viable ways, just run the relay from 18 to 8 a clock and stop it (via cron?) from 8 to 18. Or create 2 different tor configurations one limiting the bandwith to 250 kb/s and the other one to 10000 kb/s and reload tor with the according configuration (via cron) last but not least you could setup some fancy traffic shaping like in https://svn.torproject.org/svn/tor/tags/tor-0_2_0_20_rc/contrib/linux-tor-pr... where you limit the bandwith with tc and not tor itself.

Yeah but any of these are very likely to wreck your consensus weight situation, and as a result you'll be hard pressed to use the full potential of the 10000 KB/sec cap. The first option will also "ensure" you'll never get the Stable flag.

Sure if "that's what you have to work with" then there's no any better options remaining, and of these listed personally I'd suggest the reloading configs one.

From a Tor user's perspective, if a relay is periodically dropping to 250

Kb/s, a low consensus weight for that relay is probably a good thing.
