Hello,
Again I'm asking for help, because I did not fix my problem. Remembering my
story is that I have an application written using Clipper 5.2 and when a
workstation with linux+dosemu opens a file and lock a record (or the entire
file), another workstation running Windows still can open that file, meaning
that it can't see the file is locked by dosemu. Trying this operation opening
the file in Windows first, the problem still occurs.
I upgraded kernel to 2.4.18 but problem is still there.
I'm using:
kernel 2.4.18
samba 2.2.0
dosemu-1.1.2
Mr Sergey Suleymanov sent me a message telling me to use a fix (see below)
but I did not understand it. How am I supposed to use this fix? Do I have to
type it at linux prompt? Is it a script? Is it something to put into a
configuration file?
Greg LaBossiere also sent me a message suggesting to upgrade kernel. So I did
it but did not solve my problem.
Thanks,
Anderson Pereira Ataides
