Comment 4 for bug 252945

If you run "bzr push -Dhpss" and attach the output in ~/.bzr.log it will show what requests are being made, and how many bytes of content. I don't think it measures the number of bytes on the wire...

As for disabling everything... I think you can just tell tcpdump to filter out everything that isn't SSH between the appropriate hosts.

Note that you should also just do "ssh host /bin/false" to give a baseline of how much traffic it takes just to establish the SSH connection.
