I have a number of smb v1 shares. (I know that smbv1 is old and vulnerable but I can't change it) Because of the old smb protocol, I cannot use nautilus to open then. Instead, I used fstab entries to mount them. The entries in /etc/fstab look like this:

//smbserver/folder /media/user/smbserver/folder cifs credentials=/home/user/.smbcredentials,vers=1.0,noauto,user 0 0

On a Mint 19 machine, this worked like a charm, but on a new Fedora 30 installation, I only get the following error:

$ mount /media/user/smbserver/folder
This program is not installed setuid root -  "user" CIFS mounts not supported.

I already tried to set the suid bit for /usr/bin/mount, but this did not change anything.

How can I mount the smb shares on Fedora 30?

Ok, found out myself.

The following programs needed to have the suid bit set (sudo chmod u+s /bin/...):

/bin/mount
/bin/umount
/usr/sbin/mount.cifs

Some Distros do this by default. However, there seems to be discussion about the security (s-bit is always problematic).

  • Thanks for your solution. This works for NFS as well. – John Jiang May 5 at 6:44
