win95 + linux oplock error, even with kernel oplocks = no.

[Housebee]

Hi!

Thanx for the reply. I have to say that it is quite a theorie and i am going to try it. So thanx for the tip. For now my network is running half-duplex 10baseT. So not very fast with a 10baseT hub.

I read the dmb.conf again and searched for oplock. After close studing, i found this:

	When you set fake oplocks = yes, smbd(8)will always
	grant oplock requests no matter  how  many  clients
	are using the file.

I haven't tried it yet. But is this something which will work for me ? Has anyone experience with this option.

I now have this in my smb.conf:

[snip]
 # lock options
        kernel oplocks = no
        oplocks = no
        level2 oplocks = no
        locking = no
        # blocking locks = no I am not sure what this option is for....
        fake oplocks = yes # default is no.
[snip]

Mayby it works, i am going to test it soon.
I have to be there myself because i have to be behind a win95 client (blegh).

Greetz,
housebee
