rsync unexpected EOF in read_timeout

i'm trying to rsync directories from server A to server B, but i get the following error:

permission denied

unexpected EOF in read_timeout

Command is:

rsync -avzn ${LOCAL_DIR} --include-from=${INCLUDE_FILES} robin@caxs026:${REMOTE_DIR}

Server A = SunOS 5.8 Generic_Virtual sun4u sparc SUNW,SPARC-Enterprise

Server B = SunOS 5.10 Generic_150400-13 sun4u sparc SUNW,SPARC-Enterprise

• rsync daemon is running on B


• SCP is possible between A and B


• SSH from A to B or B to A is possible


• creating files while in SSH is possible

I've googled a lot of sites, but can't seem to find the correct answer. Hoping you can help me out
