SMB share automount troubles

Hi,

System : Debian Testing Trixie
cifs-utils installed

It's been sometimes, probably weeks now, I'm fighting with mount in my fstab in order to access a folder on my Synology.
Sometimes I log in and it works, sometimes it does not with the infamous message mount.cifs: permission denied.
Sometimes it works afterward, once logged in, with a

Code:

mount -a
sometimes not.
Thought I could ask for some advice :p

FYI : access from W10, W11 with ethernet OK (on the very same computer dual booting) and more interesting, access OK from popos! with WIFI (on a thinkpad).

For starter I thought I could just reuse the syntax used in the popos fstab.
Here it is:

Code:

//172.16.100.15/Video /media/nas_video cifs credentials=/home/myuser/.smbcred,iocharset=utf8,uid=1000,gid=1000,forceuid,forcegid,sec=ntlmssp 0 0

I remember I had some trouble on popos until I added sec=ntlmssp. Never failed a single time since.
So, I thought, why not use that on my new debian, right? I was wrong.
It worked a few times and then it did not anymore.
Then I started to read articles, threads, redit stuff, docs, videos, etc. with every time some new hint :

1. Options: sometimes I thought I finally had the right options (adding this, removing that): long story short, like before, worked one, two, three sessions and then bang, not anymore.

2. Credentials: check and recheck the content of my .smbcred, use 'username' and not 'user', added 'domain=WORKGROUP' just in case (have no domain on my LAN).

3. Permissions: checked the permissions of the file .smbcred (obviously created with my user): 604. Checked also permissions on the folder /media/nas_video (owner root): 755

4. Network: dmesg shows:

Code:

CIFS: Attempting to mount //172.16.100.15/VideoCIFS: VFS: Error connecting to socket. Aborting operation.CIFS: VFS: cifs_mount failed w/return code = -101
I have read that sometimes the system attempts to mount the network drive before the network interface is ready. Which makes sense. Read that _netdev can help. Tried it and didn't help.

So, right now it does not work. I know if I restart the system it might work right away or the next session. Real weird. I guess I'm missing something here.

Content of my fstab today:

Code:

//172.16.100.15/Video /media/nas_video cifs auto,_netdev,vers=3.0,credentials=/home/myuser/.smbcred,iocharset=utf8,uid=1000,gid=1000,forceuid,forcegid 0 0

Sorry for the long read. Any suggestion?

Eric
