TFTP and Jetstream 8500's

[Jeff Souter]

I am having trouble uploading configs using the
netsave command on Jetstream 8500's to hp-ux, the dir i am using is /usr/tftpdir this is where
we store our ioland configs (without problem) and now wish to store jetstream configs. However when i type in the following command (netsave config "servname"
/usr/tftpdir/test.cfg) i get the following error message TFTP: Error code 512:
Access violation.
I have tried all permissions and ownership's on the file.
I have checked inetd.conf and /etc/passwd and all the entries look fine.
Can't understand why i can upload terminal server configs from Iolan+ and not the Jetstream 8500's.
Anyone any idea's
Thanks
Jeff
