Hi!
I've seen similar topics on that list, but this time I'll
problably be going to try solving this problem myself.
It looks this way:
We want remote acces to an dos database application.
Everything's works just fine, everything but file locks ;(
I did some simple investigation (dosemu 0.99-1 - it was
before You released 1.0 , but I don't think problem was
solved there; and MS-DOS 6.22 ):
1. I checked a few dosemu's on ONE computer and dosemu
file locking works fine (strange - why ?, how ?)
2. When I run a samba or (real) novell serwer in enviroment
where are Windows clients, and (i checked one, but only for
tests, in future I would like to run more) Linux box with
a few dosemu's. File locking worked (partially) only in one
case. I lock file with dosemu - Windows sees it - I unlock
lock from dosemu - Windows doesn't see it ;( and program
waits until interrupted. Otherwise locks are not seen.
3. My friend told me (but I can't say he *must* be right)
that locks worked "better" with mars_nwe novell emulator.
(At the moment I can't exactly say what flock's the dos
program needs - probably it locks all the file, that
nobody else has acces to it at the moment)
What I need and why I wrote it ?
I haven't yet looked at all the code, but I see that problem
can be in a few layer's. I think (maybe Iam wrong at some
point?) there are such:
- Application call dos function (lock/unlock)
- it goes thru lredir
- file lock i set on UNIX FS layer
- automaticaly it goes set on server by specific server
client (smb or netware)
I would like to know where the problem is (or where isn't).
And how hard will it be to solve this. Is it possible
to solve anyway ? Where to start ?
How should be this done "right" way ? Any advices, thoughts,
any help - is welcome. ;) (To priv'a addres I think)
I'am sure dosemu team knows this problem for long time.
Have you been trying to solve this? Sure - yes.
What are Your expiriences ? Where to look for doc's, spec's ?
I wish I could push dosemu to be better a bit. I'am sure
lot's of people has similar problem. And *maybe* (hope so)
I got an occasion to clean that issue. Need to know more
about the problem.

prefer to say some things twice just to be better
understood.
