[clvk07]

Yes between guest account permissions, different behaviour between windows 8.1 / 10 was a nightmare to get to the bottom!! thanks for your help

Asus RT-AC88U with SMB2.0 enable + client Windows 10 Pro with SMB 1.0 disabled (for security), samba share of router is accesibe only over IP.
When copying a files speed is often very low, when start copying it's first seconds over 20 MB/s then freezes for 5-10 seconds and than drop <1 MB/s.
Sometimes in logs:

Aug 26 18:31:19 smbd[11418]: [2017/08/26 18:31:18.991236, 0] smbd/smb2_read.c:219(smb2_sendfile_send_data)
Aug 26 18:31:19 smbd[11418]: smb2_sendfile_send_data: sendfile failed for file VIDEO/BDMV/STREAM/1.m2ts (Connection timed out). Terminating

On FTP speed is about 36 MB/s without any issues.
I think SMB 2.0 protocol on Asus RT-AC88U is broken.

P.S.
It's on latest merlin 380.68.

Are you saying that if you re-enable SMB1 on your Windows PC that you do not have this problem copying the file?

 

[GektorUA]

I am forget to say, it's bugs only on WiFi connection (2.4 GHz/5 GHz), LAN wired connection work's good.

Hi ,
Having problems with cifs mount.
Asus RT-AC66U SMB2 enable.
Using a usb harddrive to record tv from tvheadend (libreelec)
If I enable guest account I can ifs mount and record.
But turning off guest no luck. It will not mount.
Getting this log
"Bad SMB2 signature for message
Sep 11 23:37:01 smbd[2292]: [2017/09/11 23:37:01.237999, 0] ../lib/util/util.c:415(dump_data)"
Attached a screenshot configuration

What firmware version? There are SMB2 fixes in 380.68.

Please post the contents of /etc/smb.conf

Please post the config that doesn't work, the one with guest access turned off and SMB2 turned on.

Can you give an example of the cifs mount command you are using.

 

[helio58]

Can you give an example of the cifs mount command you are using.

I have it in
storage-recordings.mount
with this configuration:
[Unit]
Description=test cifs mount script
Requires=network-online.service
After=network-online.service
Before=kodi.service
[Mount]
What=//192.168.0.2/MyPassport/Inspeladtv
Where=/storage/recordings
Options=username=admin,password=xxxxxx
# filesystem type
Type=cifs
[Install]
WantedBy=multi-user.target

Have tried with
[Unit]
Description=test cifs mount script
Requires=network-online.service
After=network-online.service
Before=kodi.service
[Mount]
What=//192.168.0.2/MyPassport/Inspeladtv
Where=/storage/recordings
Options=username=admin,password=xxxxxx,vers=2.1
# filesystem type
Type=cifs
[Install]
WantedBy=multi-user.target

But it will not mount

Make sure your Kodi box does support SMB2. I remember that for a long time, they used an old libsmb version that didn't support SMB2. I don't know if that has since changed.

 

[ColinTaylor]

Sorry I can't recreate the problem, even when I use your config. But then my client isn't Kodi.

Enabling SMB2 support on the router doesn't disable SMB1 support, so I suggest that you try forcing Kodi to use SMB1 instead.
