"laurent@laurent-iMac:~$ smbclient //192.168.1.1/USB1 ... ... protocol negotiation failed: NT_STATUS_CONNECTION_DISCONNECTED"
You are getting a "protocol negotiation failed" error because the server can only be accessed with SMB1 ( NT1 ) and there is no SMB1 ( NT1 ) in the version of samba that comes with Ubuntu 20. A better approach would be a cifs mount where you can dictate the dialect of smb but for smbclient to connect you need to add "client min protocol = NT1" and NOT "client max protocol" to your smb.conf - then restart smbd. Then smbclient will connect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1875354 Title: No more smb access after migration to UBUNTU 20.04 from UBUNTU 19.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1875354/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
