Rsync

Some tips for using rsync.

Rsync server

This can be useful to copy between nodes on RACF which do not allow node-to-node SSH. The example assumes one is running as user dayabay on RACF.

Make a config file

dayabay@daya0001:~> cat d2dcp.cfg
# rsync configuration file for host-to-host copying

port = 6969
address = daya0004
use chroot = no

[data4tmp]
	comment = test this crazy thing 
	path = /data4/tmp
	read only  = no

Additional destination stanzas can be added. The stanza name is used in the rsync URL below.

Start server

Log in to the machine where you want files to go. Start the server like:

dayabay@daya0004:~> rsync --config=d2dcp.cfg  --daemon --no-detach

Client side things

Run the client on the machine with the areas to copy. To list what is already on the destination:

rsync rsync://daya0004:6969/data4tmp/

Note, the host, port and location must match what the server reads from the config file.

To copy a source location to the server:

dayabay@daya0001:~> rsync -a -v somedirecotry rsync://daya0004:6969/data4tmp/

(leave off the "-v" for a quieter command).

Check:

dayabay@daya0001:~> rsync rsync://daya0004:6969/data4tmp/
drwxr-xr-x        4096 2012/12/07 12:28:22 .
drwxr-sr-x        4096 2011/05/05 09:38:50 somedirectory

Stop the server

When done do a Ctrl-C on the server to make it exit.
