Package: rsync Version: 3.0.6-1 Severity: wishlist As detailed in section "USING RSYNC-DAEMON FEATURES VIA A REMOTE-SHELL CONNECTION" in the manpage, it is possible to use daemon features with a remote-shell connection. The way this seems to work is that the daemon is started via the remote-shell connection, then the data are transferred *via the remote-shell tunnel*, and the daemon is taken down at the end of it all.
It would be nice if, in case rsync is used to transfer non-sensitive data, or data that is already encrypted, this sort of ad-hoc setup could be used to create a dynamic rsync protocol connection: instead of via the remote-shell tunnel, the data travels directly between client and daemon process via the TCP stack. I envision it as follows: rsync -a -e ssh --dynport host::module /dest This would cause rsync to 1. spawn an ssh connection to host 2. start rsync --daemon there, using a dynamically allocated port 3. communicate that port back to the client 4. the client now connects to that port using the rsync protocol 5. it reads 'module' and rsynchronises with /dest 6. it terminates the daemon process 7. it closes the ssh connection 8. it exits This is obviously all possible to do with a shell script, but having all of this integrated with rsync would make it a whole lot more robust. -- System Information: Debian Release: squeeze/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 2.6.30-rc5-amd64 (SMP w/1 CPU core) Locale: LANG=en_GB, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages rsync depends on: ii base-files 5.0.0 Debian base system miscellaneous f ii libacl1 2.2.47-3 Access control list shared library ii libc6 2.9-19 GNU C Library: Shared libraries ii libpopt0 1.14-4 lib for parsing cmdline parameters ii lsb-base 3.2-22 Linux Standard Base 3.2 init scrip rsync recommends no packages.
