Hello,

I have just migrated from CentOS 7.6 to Oracle Linux 8.3. I'm running a Windows NT 4 virtual machine with KVM. It had a drive mapped to a Samba share on the KVM host. Everything was fine with CentOS 7.6, but the very same VM gives me a

with the new OL installation.
Even older Linux distributions like Debian 8 refused to connect with the default settings. For security reasons the option "vers=3.0" had to be passed. That's why I believe that the WinNT problem is also related to some security setting. What I already could exclude from the root cause list:

• SELinux
• Firewall
• several registry hacks on the Windows side

Any ideas how to tell Samba to use lower security for that one share?

Thanks,
SH

P.S.: Please, no jokes about me still running Windows NT

CentOS 7.x still runs samba version 4.10 something but as of samba version 4.11 SMB V1 was removed. CentOS 8 runs version 4.11.2 so I assume OL 8 does as well.

There isn't a way to use a lower protocol unless you install an older version.

Really? So I will never get my NT-share back?

This surprises me because I've looked into the manpage of the new installation and it still mentions SMB V1 without restrictions.

I am wrong... My memory isn't as good as it used to be.

It is disabled but not removed. In your smb.conf global set client min protocol and server min protocol = NT1.

michaelk, you're my hero, it's working again!
Btw, the option "client min protocol = NT1" isn't necessary.
