clipper f/r locking failure

[Yassen Damyanov <yd@troyer.co.at>]

hi all,

I've been trying for quite some time to run a clipper accounting 
application within DOSEMU/FreeDOS (also within DOSEMU/MS-DOS 7). The 
thing runs just fine until time comes to do the clipper file and record 
locking (flock, rlock). In this case, when running two DOSEMU instances 
on one and the same machine, and files are shared via lredir, one of two 
clients hangs. (If you wonder how two clients operate on one machine at 
the same time, they are remote X terminals).

DOSEMU leaves a message like this after terminating the hang client:

"ERROR: SS selector invalid: 0x6A22, type=0 np=1"

The linux version is 2.4.20; the DOSEMU is 1.1.99. I tried with the 
FreeDOS shipped together with the binary distro of DOSEMU; also with 
MS-DOS 7 as I said already (which shows me that the problem, ot at leats 
part of it, is not in the DOS but in the emulator). The clipper version 
is 5.3b and uses standard clipper locking functions (flock, rlock). If 
any other information is needed, just let me know.

Please help me somehow to solve this. I was fighting quite a long time 
with this sole trouble. If I succeed, a well known accounting software 
in my country will get a reliable and legal open source platform to run 
on! Would be REALLY GREAT! Many people know of the experiment and often 
ask me how are things going on... I would like DOSEMU to win this case 
:-) Hope it will.

What I intend to try last (after trying so many options, like sharing a 
disk image or a real vfat partion (yes, bad ideas, but I tried these to 
see what happens), is to activate networking on each DOSEMU session and 
try to mount to a samba share somewhere on the local net.

Any comments and suggestions are more than welcome.
I would appreciate any help -- thanks in advance!

Regards,
Yassen
