Sonos SMB1 #428

Closed bosim closed 3 years ago

bosim commented 4 years ago

I am running the latest DDWRT build (43845), with syslog showing Linux kernel CIFS/SMB SERVER 3.2.3 by Namjae Jeon <linkinjeon@kernel.org>.

I am trying to get my Sonos devices using the share on the DDWRT router, however it fails. The App loads for a while and then say it cannot connect.

I then ran echo "all" > /sys/class/ksmbd-control/debug to get the debug log which gave me:

And then it stops. I tried with NT_1 as both min and max server version, same result.

Okay, Can you give me a tcpdump that captured the packets on problem ? and your client can connect with samba server ? If yes, please give me a tcpdump that captured packets between sonos SMB1 and samba.

Hmm. I this off-by-one error? Those ^B don't look right in the %s dialect output.

Yep, But I can see a print that SMB1 dialect is selected, and there are no more logs after that.
