Re^2: NFS locking with Fcntl

+1, mr_mischief.

Thanks for saying that, as it got me to thinking that maybe Preceptor might be even better off trying something like Fuse. I think it matches his requirements to-the-letter. Albeit completely without nfs; it's written in Perl, and is OS agnostic. Well tested, and requires little effort on his part.

Seems a perfect fit! :)

There's alternatives, but my actual requirement was to verify whether 'filesystem locking' works on NFS. Which is really vague, I know. But that was why I was seeking a system call based option, as that gives me a basis to say "it works" in at least an approximately language agnostic way. FWIW - on a 2.6.12+ Linux kernel, both flock and fcntl work. You will still have platform specific issues doing it regardless, but that isn't a new storage when it comes to NFS.	[reply]
