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 :-).
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
