Assuming that ~kline is /home/kline and will go to /home/kline on
the remote machine this would work (decoding the options is left
as an exersize for the student :-).

cd /home
rsync -vaHrP kline othermachine:/home

A more general solution that doesn't require ssh, but connects to
the rsync daemon on the remote machine might be to create a
module definition in the destination machine's /etc/rsyncd.conf
file something like this:

	uid = myusername
	gid = mygroupname
	read only = false
	use chroot = true
	path = /path/to/myhomedirectory
	comment = /path/to/myhomedirectory
	hosts allow = sourceipaddress
	hosts deny = *

Then the rsync command could be:

rsync -vaHrP ~/kline/ othermachine::myhome/

This has a couple of advantages.  First the destination uid:gid
can be different on the destination machine as rsync uses the
names in the group and passwd database.  Assuming you're on a LAN
where ssh security isn't critical using the daemon/module
approach doesn't require ssh authorized_keys, and can be
restricted to one or more IP addresses or CIDR blocks.

We use this when moving between systems where the uid:gid mapping
is different when moving between machines of differing OS
releases (e.g. SuSE Linux to FreeBSD), or where the destination
machine may have existing users with conflicting uid:gid s
