I'm using 2.6.9 on Solaris for both client and server.

No matter what I do the client returns the following

pre-xfer exec returned failure (-1)
rsync error: requested action not supported (code 4) at
clientserver.c(685) [sender=2.6.9]

I have run the script on the command line and it exits with a code of
0

I have even tried using simple commands like ls or even rsync --
version

I'm at a dead end, anyone got any ideas?
