Controlling bitcoin core bandwidth usage

[Bernard Lerring]

OK, so I've learned how to install and use bitcoin-qt, insert bootstrap.dat to get up to date, run a full node and run headless bitcoin core thanks to this forum.

Now that I've got a headless node running I'd like to limit my upload speed, if possible, to keep it below 50Kb/s. My connection is 100Kb/s max and I don't want it interfering with other stuff I'm running, like torrents.

I know I can limit the number of connections (thanks DeathAndTaxes) but this doesn't necessarily mean that my upload isn't being max'ed out.

Is there a command line option to set a maximum up speed?

You could try netlimiter. I believe you can control the bandwidth of individual applications and monitor them as well with the tool.

What OS?  There are software options, and routers can limit bandwidth as well.

I'm using the latest Ubuntu.

I'm using the latest Ubuntu.

One option is iptables -m limit.

Another option is something like trickle, but I've never really gotten it to work well.

I've looked at google results and it seems like maxconnections=12 will have to do for now.

I hope an uplimit=x downlimit=x setting is implemented in future.

Works for me.

yeah trickled is pretty cool.
what type of router ? quite a few of the routers with newer images have rate limiting features these days.
