[Duplicity-talk] why is rsync backend using ssh?

[edgar . soldin]

while checking out the rsync backend I got confused

in plain command line the following happens:

#> rsync /tmp rsync://address@hidden/test -vvv
opening tcp connection to host port 873
rsync: getaddrinfo: host 873: Name or service not known

but the same call in duplicity's rsync backend connects to ssh (port 
22). see below.
I couldn't figure out how the backend switches modes. Interestingly 
defining an url like
rsync://user:address@hidden::test
seems not to utilize ssh.

What am I missing? .. thanks ede/duply.net
