Hi,

This is a sequel to this story, kind of. It's bordering on offtopic, too, but Dolphin is involved still.

Until yesterday it's been fine. Right now the shares are unmountable (Dolphin message):

An error occurred while accessing 'Obmen on 192.168.0.125', the system responded: mount: only root can mount //192.168.0.125/Obmen on /home/alexey/smb4k/WSERVER/Obmen

/etc/fstab:

//192.168.0.125/Obmen /home/alexey/smb4k/WSERVER/Obmen cifs noauto,uid=1000,credentials=/home/alexey/.smbcredentials,x-systemd.automount 0 0

sudo apparently works as usual (the only recently upgraded package remotely relevant).
The system doesn't believe in my access rights any more, but why? Now and then (by no means always) the Device Notifier (KDE) asks for my user password to mount a mobile phone, but this is far less lethal.

stat `which mount.cifs`
it's probably not suid (for security reasons) - just google for the error message.

A binary file. Doesn't tell me anything, unfortunately.

Manual mount:

$ sudo mount -t cifs //192.168.0.125/БОС /home/alexey/smb4k/WSERVER/БОС/ -o uid=1000,username=user,password=passwd
Couldn't chdir to /home/alexey/smb4k/WSERVER/БОС: No such device
$ sudo mount -t cifs //192.168.0.125/Obmen /home/alexey/smb4k/WSERVER/Obmen/ -o uid=1000,username=user,password=passwd
Couldn't chdir to /home/alexey/smb4k/WSERVER/Obmen: No such device

БОС and Obmen apparently exist; I can't enter them, though:

Could not enter folder /home/alexey/smb4k/WSERVER/Obmen.

important bits are that mount.cifs *is* suid, so that's not your problem.

Couldn't chdir to /home/alexey/smb4k/WSERVER/Obmen: No such device

What's the output of

Code: Select all

lsmod | grep cifs

$ lsmod | grep cifs
cifs 361277 0
fscache 47797 2 nfs,cifs

Sorry, out of ideas about the usual suspects. IIUC, the server is as windows machine - might be a compatibility issue? Tried connecting to a samba server?

It used to be quite compatible, until recently.

Which way? I'm not well versed in the thing...

Can you please try executing mount.cifs directly? (substitute "mount -t cifs" for "mount.cifs")

No luck.
Also this:

I'm afraid you've found the problem, even though mount.cifs is reporting it wrongly.

Code: Select all

Error returning browse list: NT_STATUS_ACCESS_DENIED

You need to adjust the configuration of the Windows system accordingly.

Server side problem. Here I am at the mercy of my Admin. Fortunately, it surfaced at last on Windows workstations, too. There's hope .

Turned out to be merely the Windows user password expiration. It was a healthy experience, nevertheless. Thank you, guys!

Thanks - I've now marked this issue as solved.
