Hello all, I saw on the Release notes that 2.6.0 is using protocol version 27 which is different than 2.5.7 and 2.5.6. I did a quick peak through the rest of the release notes and quickly browsed the archives on the list and I didn't see any notes on how well 2.6.0 works with older versions of rsync. At our site, we do have 2.5.7 and 2.5.6 installed. Are there any documented problems when using 2.6.0 with a down revved version on another system?

If I'm not mistaken, they stopped support for protocol version 19 and below. This would only affect you if you were using a version of rsync that was older than (going out on a limb here) 5 or so years old. -Chuck -- http://www.quantumlinux.com Quantum Linux Laboratories, LLC.

When a newer version is communicating with an older the will use the highest common protocol version. We do limit the backwards compatability somewhat and will exit with an error if you try to connect between incompatible versions. Beginning with 2.6.0 there is also a warning if connecting to a version that may not be supported by the next release. In addition to the protocol errors there may be newer command-line options so if you are using a new client and try to use a command-line option not supported by an older server the server will exit with an error message. For the most part you don't need to worry about the protocol versions. On the other hand in addition to feature enhancements, over time we fix bugs and improve performance and if you do have problems only limited support is given to older versions. As for your situation 2.5.6 and 2.5.7 are not that old. Some distributions are still shipping much older versions. -- ________________________________________________________________ J.W.
