This program is not installed setuid root - "user" CIFS mounts not supported

farfad · April 7, 2024, 5:05pm

Hello,
I’ve been having this problem for a few weeks now. Everything worked perfectly before and my method has always been the same for years and on several distributions. For me the SUID bit represents a security problem but I’m not an expert. I’d like to understand what change has been made in Fedora workstation 39 that now prevents my network drives from being mounted via the fstab file.Everything work perfect when i do a mount - a with the root account …

My credentials file stored in /root :
-rw-------. 1 root root 63 1 avril 16:26 .smbcred
my fstab :
//192.168.0.3/ISO /media/nas-iso cifs credentials=/root/.smbcred,iocharset=utf8,gid=1000,uid=1000,_netdev 0 0

fstab is turned into systemd-mount units automatically and as root the mounts are performed.
So setuid is not required.

Look for information in the journal for the mounts.
You can find the mount units with systemctl | grep mount and find the status of a .mount unit with systemctl status home.mount (for example).
Or look at all mounts with journalctl -b 0 -g mount.

Hello,
Thank you for taking the time to reply.
In the meantime, I modified my fstab to see if I had the same problem with NFS. It’s exactly the same.
Attached is the screenshot with a track, “Network is unreachable”.
However, I have the _netdev option in the fstab to wait for the network to be available before attempting to mount.

Hi, same thing with Fedora 40

scorpoon · June 7, 2024, 7:36pm

~~Someone already got a solution for this? I just found a few search results where it’s told to change the permissions of a few /bin/ files and i hope that this isn’t actually a thing~~

Nevermind, i forgot to add the name of the shared folder, output of dmesg showed me the right direction so i checked the name of the share once more in fstab

farfad · June 8, 2024, 8:28pm

Any ideas ? when i do a sudo mount -a everything work fine. i have to do this everytime i reboot my computer… Regards

Where does the error message in the title come from?
The log you posted above shows a different problem that looks like a race condition.

farfad · June 9, 2024, 7:34am

I’ve just restarted my PC to send you the logs, everything seems to be working properly now. We can close the subject
