Unix systems should use NFS for file sharing. netbios is a tangled mess of poorly planned protocols with extensions on the extensions, and warts on the warts (ports 137/138/139 were old NetBIOS, using NetBIOS-over-TCP aka NBT as the transport, while port 445 is the newer native CIFS protocol introduced around Windows2000 time). with NFS, you'd mount the backup directory somewhere, like /nfsbackups just once at bootup time and each user would have their own directory in it, /nfsbackusp/fred (or whatever) and only have read/write access to that directory, managed via standard unix style chmod, chown ... -- john r pierce N 37, W 122 santa cruz ca mid-left coast
