Hi,

please avoid top posting.
It needs "reconstruction" to see the history.

We have a very high utilization rsync server. We can handle large
number of connections at a time, but would like to limit to one
connection per client. we don't want multiple connections from the
same client. Is that possible?

With the help of xinetd.

Example:

ftp5:2 22:39:02 ~ # cat /etc/xinetd.d/rsync
# default: off
# description: rsync file transfer daemon
service rsync
{
       socket_type     = stream
       protocol        = tcp
       wait            = no
       user            = root
       server          = /usr/sbin/rsyncd
       instances       = 999
       per_source      = 19
       server_args     = --daemon
#       disable         = yes
}
ftp5:2 22:39:03 ~ #

Thanks for the quick response. Can you please explain how this would
work? I am not very familiar with xinet.d, and I don't see a rsync
file in the /etc/xinetd.d/ dir.

You just do not start rsyncd autonomously during boot, but "only" xinetd.

xinetd will handle all incoming connections for which a configuration file in /etc/xinetd.d/ exists. So your rsyncd gets started by xinetd, and xinetd will obey f.e. instances and per_source before starting a next rsyncd instance.
