Make SMB2 as default
Last modified: 2013-11-19 06:43:29 CET
The value for "server max protocol" should be set to SMB2 for new installed UCS systems.
The default has already changed with 4.1rc2:
root@master151:~# samba -V
root@master151:~# testparm -vv 2>/dev/null| grep 'protocol'
server max protocol = SMB3
server min protocol = LANMAN1
client max protocol =
client min protocol =
root@master501:~# samba -V
root@master501:~# testparm -vv 2>/dev/null| grep 'protocol'
max protocol = NT1
min protocol = CORE
testparm.samba4 outputs SMB3 for 4.0.3 as well. I checked with a Windows7 client and see in the logs: "Selected protocol SMB2_10". Windows8 would probably negotiate SMB3.
For samba 3.6.8 testparm says NT1 and the Windows7 client test confirmed this.
SMB2 is set fpr Samba 3 and Samba 4 for new installation. For updates from 3.1 to 3.2 NT1 is used.
