Hello all,

I have a USB drive attached to my AX10000 router. I'm able to map that share to multiple windows 10/11 clients on my network. I have a Raspberry Pi 5 client that has been updated to the latest software. I have the latest CIFS software installed. I can ping the ax10000 from the raspberry pi. I'm using the following mount command as the root user on my RPI 5:

# mount -t cifs -v -o username=???? //192.168.##.###/G/HomeBackup/jfranklyn /mnt/windows_share

After I enter the password that I've set on the ax10000, I get the following error:

mount error(22): Invalid argument

The linux share: /mnt/windows_share is owned by root and I've granted full access to anyone on this folder.

On the RPI 5, I run the dmesg command to see the full error message:

[ 1275.638186] CIFS: No dialect specified on mount. Default has changed to a more secure dialect, SMB2.1 or later (e.g. SMB3.1.1), from CIFS (SMB1). To use the less secure SMB1 dialect to access old servers which do not support SMB3.1.1 (or even SMB3 or SMB2.1) specify vers=1.0 on mount.

I'm not sure how to verify the SMB version on the AX10000. I know linux spits out lots of error messages, so I'm also not sure if I'm chasing a bogus SMB version error.

I know you can't help me with the RPI 5 configuration. I was hoping someone had gotten a similar linux client mount to work.

Thanks
