I'm trying to us grsync to keep 2 instances of my music library synced across my home network
I can access both locations using ssh & manually copy & paste the files
when I try grsync on this computer I can moved & sync files between the external usb drive & the music files on this computer

when I try to go accross the network I get this:
Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,password).
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(601) [sender=3.0.7]

during the process I get prompted for my password 3 times
