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 1 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-prio.sh
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 1 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.

I think I will write a script which will change bandwidth base on the number of 
incomin connections to my varnish server. Then there is a big chance to keep 
stable flag on.
Thank U for all that ideas ;)))

Two other possibilities:
* always run the relay at 250kbps
* run a bridge instead (I don't know if 250kbps is still considered enough for 
a bridge)

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.

Re: [tor-relays] Custom bandwith for different time ranges

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.

As suggested in an earlier reply, configuring 'cron' jobs to adjust the rate 
usually makes sense.

As an alternative to modifying 'torrc' and sending SIGHUP to the daemon, you 
could use a control-channel script similar to:

nc 127.0.0.1 9151
