And lockf can't do this. I assume special-case code is needed in CAP to recognise and "translate" the request into something that can be done by the Unix file system. tecot@momenta.com (Ed Tecot), in comp.sys.novell,comp.sys.mac.system writes: > At Apple, compatibility is very important; it's SOP to fix a third > party's bug in system software if possible. Is it too late for the byte-range-lock-zero-length-read-only behaviour to be changed (or has it already)? What concerns me is whether: CAP/AUFS Pacer Alisa Novell PATHworks Mt Xinu UShare NFS/Share Pathway NFS all the other ones I've forgotten can handle this now, or if they have to be changed to accommodate System 7. ======================== Tom Evans tom@wcc.oz.au ** ADD ".au" MANUALLY (don't trust "reply") ** Webster Computer Corp P/L, 1270 Ferntree Gully Rd Scoresby, Melbourne 3179 Victoria, Australia 61-3-764-1100 FAX ...764-1179 A.C.N. 004 818 455

NFS/Share seems to work well under System 7, although it does require
a working rpc.lockd on the UNIX side, which is a surprisingly rare
beast. If you run bwnfsd (which you should be able to get from Beam
& Whiteside or InterCon), it'll use it for locking instead, as I
understand.
Disclaimer: I'm an NFS/Share tester--contact InterCon for the official
scoop on the state of NFS/Share.
