mount error: cifs filesystem not supported by the system

tonj · 11-19-2016, 09:02 AM

I'm running a vps which my vps-provider tells me is an OpenVZ container - but I don't know what that means. I have centos 7 64 bit installed on this vps and I'm trying to mount a share at a remote location using this command:

Code:

mount -t cifs -o username=<username>,password=<password> //<remote-ip>/share /media/smb-share

but I get:

Code:

mount: unknown filesystem type 'cifs'

so I installed cifs-utils and ran the command again but this time I get:

Code:

mount error: cifs filesystem not supported by the system
mount error(19): No such device
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

The '<remote-ip>/share' location is working fine because I've tested it on other machines so the problem is with the vps. Is there a way to get this to work on the vps I have?
ps: if it's any help...

Code:

# uname -a
Linux <hostname> 2.6.32-042stab113.11 #1 SMP Fri Dec 18 17:32:04 MSK 2015 x86_64 x86_64 x86_64 GNU/Linux

To find out what filesystems are supported by the running kernel, do:

Code:

cat /proc/filesystems

If cifs is not listed do:

Code:

sudo modprobe cifs

don't see cifs there...

# sudo modprobe cifs

gives nothing, cursor just drops to the next line.

The idea of using Samba over internet gives me creeps. It may be impossible, too. If you are trying to connect to a home machine your ISP may block the ports.

I agree that exposing CIFS ports to the internet is a security concern and puts your remote network at risk. It is also true that some ISPs block CIFS ports.

However, it may may not be possible unless you have access to the host.

Note: many commands like modprobe do not output any status messages if completed successfully.

I have the samba ports at '//<remote-ip>/share' locked down to restricted ip's in iptables so the security of this is not what I'm asking about. Thanks for the link, I don't have access to the host. Is there any other way around this?

I don't know but using fuse and sshfs (sftp) may be an option.

NFSv4 was designed to work over untrusted networks.

@BW-userx, and where in all those links does it explain how to mount a share from within an openvz container?
