samba 3.6.x and max protocol = SMB2

S

Sylhouette

Hello all.

Using the newer Samba server 3.6.1 for a while, but when I turm on max protocol = SMB2, Samba core dumps on me when I try to upload a large file like a FreeBSD DVD ISO to the samba server. This only happens from a windows 7 and up BTW, XP does not have that problem. Would make sense because XP does not have SMB2.

I first encountered this on a test machine, and therefore I thought it was something with the machine itself, but every server I use now, has this same issue.

Is any one using max protocol = SMB2 with succes in combination with windows 7 and up.

My main machines are domain members, but even a fresh install and creating a user with smbpasswd shows this issue. For the record, my smb.conf from such machine.
Maybe another setting is the problem.

Hi, I turned on SMB2 today and copied a few large ISO images back and forth between Win7 and samba36 without any issues. I know this doesn't really help you per say but at least now you know that it can work. My Win7 is using standard stock security and protocol options (I mean I am using the stock registry).

I'll let you know if I have any further problems since it is a realtively fresh install. I would suggest you disable some of your samba tweaks that are not necessary and give that a try with SMB2 and see if it works.
