vast copy is broken

[thandal]

Using the latest version

wget https://raw.githubusercontent.com/vast-ai/vast-python/master/vast.py
chmod +x vast.py

I can't copy from a running instance, for example (all ports, ip addresses, etc, have been anonymized):

$ vast.py copy 55555555:/root/logdir local:logdir
copying 55555555:/root/logdir local:logdir
rsync -arz -v --progress --rsh=ssh -e 'ssh  -p 48888 -o StrictHostKeyChecking=no' vastai_kaalia@155.55.55.111::55555555//root/logdir logdir
Enter passphrase for key '/home/user/.ssh/id_rsa': 
@ERROR: Unknown module '55555555'
rsync error: error starting client-server protocol (code 5) at main.c(1863) [Receiver=3.2.7]

But if I munge the rsync command using the SSH ports from the web interface, and root@ instead of vastai_kaalia@, and remove the instance id from the remote path, then it works fine:

rsync -arz -v --progress --rsh=ssh -e 'ssh  -p 477777 -o StrictHostKeyChecking=no' root@155.55.55.111:/root/logdir logdir
