What kernel version are you running?  I noticed some strange behavior with
tar and some of the later kernels that I haven't had time to investigate.

Any messages in /var/log/messages or dmesg about I/O errors, etc.???

Did it ever work?  Did it suddenly stop working?  If so, what changed?
(new kernel, ....?)

Otherwise you may need to "strace" tar to figure this out.

It is NOT secure and should only be used on machines behind a good firewall.
I think it requires an entry in the remote machine's /root/.rhosts file for access.
