1WHAT IS RSYNC? 2-------------- 3 4rsync is a replacement for scp/rcp that has many more features. 5 6rsync uses the "rsync algorithm" which provides a very fast method for 7bringing remote files into sync. It does this by sending just the 8differences in the files across the link, without requiring that both 9sets of files are present at one of the ends of the link beforehand. 10At first glance this may seem impossible because the calculation of 11diffs between two files normally requires local access to both 12files. 13 14A technical report describing the rsync algorithm is included with 15this package. 16 17 18USAGE 19----- 20 21Basically you use rsync just like rcp, but rsync has many additional 22options. To get a complete list of supported options type 23 24 rsync --help 25 26and see the manual for more information. 27 28 29SETUP 30----- 31 32Rsync normally uses ssh or rsh for communication. It does not need to 33be setuid and requires no special privileges for installation. You 34must, however, have a working ssh or rsh system. Using ssh is 35recommended for its security features. 36 37Alternatively, rsync can run in `daemon' mode, listening on a socket. 38This is generally used for public file distribution, although 39authentication and access control are available. 40 41To install rsync, first run the "configure" script. This will create a 42Makefile and config.h appropriate for your system. Then type 43"make". 44 45Note that on some systems you will have to force configure not to use 46gcc because gcc may not support some features (such as 64 bit file 47offsets) that your system may support. Set the environment variable CC 48to the name of your native compiler before running configure in this 49case. 50 51Once built put a copy of rsync in your search path on the local and 52remote systems (or use "make install"). That's it! 53 54RSYNC SERVERS 55------------- 56 57rsync can also talk to "rsync servers" which can provide anonymous or 58authenticated rsync. See the rsyncd.conf(5) man page for details on how 59to setup a rsync server. See the rsync(1) man page for info on how to 60connect to a rsync server. 61 62 63MAILING LIST 64------------ 65 66There is a mailing list for the discussion of rsync and its 67applications. It is open to anyone to join. I will announce new 68versions on this list. 69 70To join the mailing list see the web page at http://lists.samba.org/ 71 72To send mail to everyone on the list send it to rsync@samba.org 73 74 75BUG REPORTS 76----------- 77 78If you have web access then please look at 79 80 http://rsync.samba.org/ 81 82That page contains links to the current bug list, and information on 83how to report a bug well.
