SMB 1.0 (Given Wanna Cry)
Out of curiosity in the latest 6.7.1 firmware is SMB 1.0 disabled?
Can we control SMB so that it ONLY used 3.0 or 2.0-3.0 for example?
The Wanna Cry issue used an attack vendor to attack Windows machines that hadn't had a security update installed. Our NAS units don't run Windows.
The latest RAIDiator 4.1.x and RAIDiator-arm uses samba 3.5.x. The latest RAIDiator-x86 4.2.x uses samba 3.6.x
Experimental SMB2 support was added in samba 3.5.x, but really you should be using a newer version of samba to use it. 3.6 isn't much newer. I'd be wanting to use newer than that. To my knowledge we don't have any plans to update samba on these old OSes.
I think SMB2 support is turned off by default on all those models.
OS6 currently uses samba 4.4.x, a much newer samba series.
I've passed on the feature request to be able to disable SMB1 support from the GUI for OS6 devices.
Disable SMBv1 and enable SMBv2 on your PC (Windows7 or Windows8 or Windows10, 32-bit or 64-bit.):
a) Open command prompt with administrator rights (press "Win" button, type “cmd”, right-click "cmd.exe" and select "Run as administrator"
b) copy the text below, paste it into command prompt and press Enter
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters" /v SMB1 /t reg_dword /d 0 /f reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters" /v SMB2 /t reg_dword /d 1 /f sc.exe config lanmanworkstation depend= bowser/mrxsmb20/nsi sc.exe config mrxsmb10 start= disabled
c) reboot PC
Thanks. I know.
