Rsyncd

From CHG-Wiki

To help facilitate pushing incoming data to CHG, an rsyncd server has been set up on range. Currently, this does not so much replace the ftp-in function as supplement it, though eventually it will likely replace ftp-in.

Gettings Started

To push data to CHG servers, you will need a Unix-based command line interface equipped with the rsync command.

Windows

There are several options for Windows users who want a Unix-based command line interface. One of the most commonly used programs is Cygwin. You can find more about installing Cygwin here. Make sure to select rsync as one of the packages when you install. You may want to check for the "mirror" (or website you will download the Cygwin files from) closest to you here. Keep in mind that installing Cygwin, especially if you choose to do a full install, could take quite a while.

Another option is putty.

Mac/OS X

You should be able to use the built-in Terminal program to use rsync.

Command Line

[user@server ~]$ rsync -avh foo.txt rsyncd.chg.ucsb.edu::[rsync-destination-point]

Where "foo.txt" is the file or path to the file(s) to be rsync'd and rsyncd.chg.ucsb.edu is the rsyncd server (located on range), and the ::[rsync destination point] is the predetermined location where you want to push your data. For example:

[libby@rain ~]$ rsync -avh logo.gif rsyncd.chg.ucsb.edu::SWALIM
sending incremental file list
logo.gif
 
sent 38.43K bytes  received 27 bytes  76.92K bytes/sec
total size is 38.34K  speedup is 1.00

Pushes the file logo.gif to the rsyncd location SWALIM. Take note of the files listed under "sending incremental file list". Any files already present in the destination will not be listed. For example:

[libby@rain ~]$ rsync -avh logo.gif rsyncd.chg.ucsb.edu::SWALIM
sending incremental file list
logo.gif
 
sent 38.43K bytes  received 27 bytes  76.92K bytes/sec
total size is 38.34K  speedup is 1.00
[libby@rain ~]$ rsync -avh logo.gif rsyncd.chg.ucsb.edu::SWALIM
sending incremental file list
 
sent 44 bytes  received 8 bytes  104.00 bytes/sec
total size is 38.34K  speedup is 737.33

To send an entire directory, the process is the same. Instead of listing the filename, list the directory name or the path to the directory.

[libby@rain ~]$ rsync -avh foodir/ rsyncd.chg.ucsb.edu::SWALIM
sending incremental file list
./
foo.log-20150215
foo.log-20150217
foo.log-20150222
foo.log-20150301
foo.log-20150304
foo.log-20150308
test/
test/foo.testlog
test/foo.testoutput-20150723_130024
test/foo.sh
 
sent 590.17M bytes  received 608 bytes  90.80M bytes/sec
total size is 590.10M  speedup is 1.00

rsyncd Locations

rsyncd destination points must be requested and set up in advance. Please contact chgadmin@geog.ucsb.edu to request a destination point.

If the user wants an rsync destination point that will be immediately available via ftp-out, they will need to provide an IP for security reasons.
