I'd recommend that you do a search on the failing systems for duplicate or old copies of Rsync. It just takes a PATH variable to include another old copy of rsync to make it fail.
I'd also check your firewall or router aren't the problem. If you need to, temporary disable the firewall or any AV software as these can be potential problems. Also are you using SSH on these systems? Perhaps that isn't working? I'd start with the very simplest set up and go from there. For example manually start up a daemon on a remote server and see if a client can connect to its resources. Try a different port number, some thing may be blocking the value you're using. P.S. No need to send me a personal copy of your reply. I do read the mailing list. I get quite enough email thanks. :-) -- Stuart Halliday This email is the property of ECS Technology Ltd.
