[rdiff-backup-users] version mismatch not identified

[Nicola Fankhauser]

hello

I just installed rdiff-backup on two machines and it just did not run -
later on I saw that I had different versions on them (one from debian
unstable (0.10.1 something) and one stable (0.6 something)).

So my first suggestion (while I could not really test-drive it yet, but
will ASAP) to rdiff-backup is some sort of version match when connecting
to a server, so that strange errors like these no more happen:

Fatal Error: Truncated header string (problem probably originated
remotely)

Couldn't start up the remote connection by executing

    ssh -C 192.168.2.21 rdiff-backup --server

Remember that, under the default settings, rdiff-backup must be
installed in the PATH on the remote system.  See the man page for more
information.

anyway, keep up the good work, this is a great tool!
