@xazac It looks like the current version of unraid (7.1.4) is still running Samba version 4.17.3 (CVE-2022-42898). @03fc35ss posted an update as this newer version of Samba looks to have some different settings/syntax/etc... His updated settings are: server min protocol = SMB3_11
client ipc min protocol = SMB3_11
server signing = mandatory
client NTLMv2 auth = yes
restrict anonymous = 2
null passwords = no
raw NTLMv2 auth = no
smb encrypt = required
client signing = required
client ipc signing = required
client smb encrypt = required
server smb encrypt = required@ericswpark found the version minimums for the server/client version were incompatible with IOS and proposed to use different minimum settings (below). server min protocol = SMB3_02
client ipc min protocol = SMB3_11I just discovered this article and plan to test it with my osx/ios devices, so we'll see.
