Hi,

I tried:

Found a workaround: Throttling of the bandwidth.
- Throttling at the network adapter level [1] is not applicable to Hurd.
- The 'throttle' program [2] is no longer available.
- But a replacement program [3] is available.

The command that worked for me (it limits the bandwidth to 1 MB/sec):

# tar cf - directory | ~/throttle.py --bandwidth 1024576 | ssh [email protected] tar xf -

But really, this is only a workaround. It smells like a bug in ssh or the Hurd.
