U4 - can't create mount for a T3.

[Paul_oz53]

This problem seems to echo the problem Star6key had with his U4 accessing recordings on a V2. However, this concerns a U4 accessing recordings on a T3.

The story is as follows:

• Received the repaired T3 and set it up from scratch.
• Replaced the HDD and reformatted it.
• Upgraded T3 to 19.3 20201011. Generally working fine.
• Had to reformat the HDD again as it initially complained that it could not setup the hard link for time shifting. First time it setup on the USB stick!
• Rescanned, created Favourites
• Setup networking by DHCP (router assigned IP address)
• Stopped DLNA, set root password
• Created network mounts to the T4, U4s, one PC and confirmed all could be accessed.
• Setup IceTV.

Note that I have not edited any of the SMB configuration files on the T3. On inspection, they're set to the default insecure configuration that allows SMB version 1 (oddly but correctly identified as version NT1).

The problem:

The U4 can't access recorded files on the T3. The U4 network browser can see it, create a mount and seemingly mount the movie folder. However, on attempting to access the T3 recordings, the media player reports the error that the T3 movie folder does not exist?

I've tried it with and without vers=2.1 in the U4 mount options but no difference. The T4 works if the 2.1 parameter is omitted. The U4 refuses to work. Note that auto.network and automounts.xml match and contain no extraneous characters.

Curiously, using the same technique to create a mount on the T4 worked. The T4 can see the T3 and access it!

The U4 and T4 can see and access recordings on each other. However, the U4 media player cannot access the recordings on the T3. Similarly, the U4 cannot access recordings on the T3 by File Commander either.

Moreover, the T3 can see all the other network devices and access them without a problem.

I suspect that there is something about the U4 configuration that has caused the problems with the T3 and previously reported problems with V2 connections.

Note that the U4 can connect to my Windows PCs, the T4 and to the other U4 without a problem.

Like Star6key, we use the U4 to watch recordings and rely on the network to access recordings made elsewhere. Although I can watch the T3 indirectly connected via the Denon, it annoys the other half to do so (the T3 picture is much darker than the U4).

Any thoughts of options to try are welcome.

Assuming the automount happens, see if the issue is with samba on the T3 by adding "log level" debugging to the "global" section of the Samba "user changes" config file (/etc/samba/smb-user.conf) -

Code: Select all

[global]
#       include = /etc/samba/distro/smb-secure.conf
log level = 2

Wait 30 secs or so for the change to be detected, then access one of the T3's exports (e.g. /media/hdd/movie) on the U4 and then check the output of the resultant debugging in /var/log/samba/log.smbd (on the T3).
I'd expect there to be at least an authentication listed for the access of the T3 from the U4 (assuming the automounter has mounted the share on the U4).

Thanks Grumpy_Geoff, I will give it a go but SWMBO is watching the TV right now. Could be a while before I get access.

[Grumpy_Geoff]

I don't think you'll need to disturb "she who must be obeyed" at all, as it should be achievable from your computer (no risk of a kick to the goolies ) -

• Telnet to the T3, edit /etc/samba/smb-user.conf
• [waiting the 30 secs or so]
• Open U4's OWIF via browser
• Open Movies link under Main
• Click on "media" to expose drop-down selector
• Select "autofs"
• Select mount for T3's Movie export
• Back to the T3's telnet session, check the samba log less /var/log/samba/log.smbd

[the OWIF access to the share could be replaced with a telnet to the U4 and accessing the share - ls -al /media/autofs/{T3_Movie})

Hi Paul,

These are the settings I use to connect to my T3 from the U4. I use FSTAB instead of Autofs. Can't remember why but it works

Thanks again GG. Had to go out for a while. I'm old enough to have enjoyed "Rumpole of the Bailey" who first brought SWMBO to my attention.

At the step "Select mount for T3's Movie export" a spinner appeared and didn't finish. However, the U4 showed the Movie folder icon in green, which should mean it is mounted.

However, earlier I did manage to get the log.smbd file which is attached below. (This came with some protest but hey, she left the room for five minutes!)

Being in the study, I could access a U4 but my most recent attempts from the other U4 were equally unsuccessful. Though not included, here, the lines in the log after trying the study U4 exactly mirror the attached file.

I note that line 4 contains an error report "...SO_REUSEPORT = true on port 445 failed with error = Protocol not available", which may indicate the nature of the problem I'm having but this is well above my paygrade. Not apparent what the missing protocol might be or if it matters.

Regards, Paul

PS: On closer inspection, the PCs can't expand the movie or the logs folder on the T3 using Windows Explorer but Openwebif can download recorded files. The T3 can read and write to the PC though.

I presume you know that Rumpole was in turn borrowing from H Rider Haggard?

A big thank you! May your team be successful no matter what brand of football they play.

Yes, it works if I use FSTAB, vers=2.1 and add the root account username and password.

Interestingly, the folder path is /media/net/movie. When time allows I will try to find the parameters that matter.

Dig deep, there's something quite strange about all that.

Possibly pointing at the T3's samba server, you think?

but Openwebif can download recorded files.

I'm pretty OWIF is using http file streaming, not samba to access the recordings.

I think the mounting of fstab shares on /media/net is the usual location.

When I tried the samba debug logging earlier, I had an "authentication" message appear, whereas you didn't -

Just snuck a look at log,smbd and it does appear that the addition of a username and password is the key. It now includes the authentication entries you mentioned. It finds and accepts the root account credentials.

Will try autofs as you suggest after the footy.

Update 1: Autofs is working now with the root username and associated password. Initially it didn't work but after about 15 minutes it came good without a reboot. The share now shows as /media/autofs/MovieT3.

Update 2: On rebooting the U4, autofs did not work. Reverting to fstab and rebooting did work. It appears fstab is a necessary setting along with the root username / password.

Have you also tried fstab with user=guest?

In your case, fstab mounting likely won't be so bad as your T3 will be kept in standby to prevent the "disappearing hard drive from boot" issue, so the mount on the U4 should always succeed.

She-who-must-be-obeyed is the eponymous "She" of H Rider Haggard's She: A History of Adventure.

It appears to work ok with user=guest and no password. I have had a spontaneous reboot and a lockup of the U4 today but I am not able to investigate why at the moment.


And yes, the T3 will be on standby.

Update: The reboot appears to be unrelated. An IceTV problem appears to have been the cause. IceTV issue now resolved.
