Wonder if perhaps its the reverse problem, and it can't *create* a lock
file .. can you "touch anyfile.txt" to see if that's OK? The directory
permissions look ok...

Otherwise, next port of call would be NFS share settings, and whether
its doing permissions by numeric IDs or something else....

There's an option for 'ls' which gives you numeric IDs for the
permissions, and possible even try 'stat' on the file to see what that
says ...

The 'julian' ID is the same numeric on desktop/laptop/NAS/etc too ?

Gotta be something really silly .. it always is ... ;)
