[Fwd: Re: Samba and kernel oplocks - Smbmount]

["Oscar A. Valdez" <oscar.valdez@plastipak.com.sv>]

I forgot to mention that I had to substitute the FreeDOS kernel that
comes packaged with the binary Dosemu 1.0.2.x distribution (version
2024?) with kernel.sys version 2026.

Kernel versions earlier that 2026 do not handle locks on lredir'd
drives.

I'm accessing Samba shares with Dosemu 1.0.2 and 1.0.2.1. File locking
works flawlessly and with simultaneous access by Window$ clients.

I mount the Samba share with

mount -t smbfs //SERVER/SHARE /mnt/MOUNTPOINT -o credentials=CREDENTIALS_FILE,workgroup=WORKGROUP,rw,gid=GID,fmask=770

and then, within Dosemu

lredir F: linux\fs/mnt/MOUNTPOINT

(Of course, all the stuff in capitals needs to be substituted correspondingly).

Works fine.
