Q: Rsync, Batch: How to avoid the "password" ask ?

[Tim Conway]

You're getting there.  Save yourself some typing, though, and simplify 
your commandline until we get auth working.  just "rsync 
bart2@%BSERVER%::backup_pa"  get the list and we're past the hurdle.
Looking at what you're doing, my guess is that you have world read on your 
secrets file - /etc/rsync.scrt.  set it to  u+rwx,go-rwx, i.e. 600, and 
try again... or, if you have no possible security concerns about your 
logged-in users, leave it whatever you want and add "strict modes = no" to 
the module so it won't care any more.
Note:  unless /mnt/hdc1/backup has o+rwx, or nobody ownership, the nobody 
user isn't going to be able to write.  I'd suggest that if you're having 
only bart2 use it, and he's a real user, have bart2 own it and be the uid. 
 If it's for multiple users files, make it root, and rsync will handle 
ownerships.
DON'T make the rsync auth user name "root" - hell, don't make it anything 
that has system access.  Everything you use runs as the uid anyway. Better 
yet, give each user his own module, running as himself.

If you're safe inside your own lan, ignore my security paranoia.

Hi Tim,

Thanks for the info ... and the congratulations ;)

but now when I try to do this in a batch file :
SET BSERVER=192.168.0.102
SET RSYNC_PASSWORD=bart2
rsync -av --delete "/cygdrive/c/Doc/backup/Desktop/MesFavories.rar" 
bart2@%BSERVER%::backup_pa

I got the following error :

@ERROR: auth failed on module backup_pa
rsync: connection unexpectedly closed (94 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at 
/home/lapo/packaging/tmp/rsync-2.6.2/io.c(342)
