[SOLVED] How do I copy files from CentOS 7.3.1611 (Core) to a Windows NFS Share

SecGuy · 05-24-2017, 09:37 AM

I created a bash script to backup some files on my CentOS (7.3.1611 (Core)) which are now in a tar.gz on my CentOS server. I need to copy these files from the CentOS server to a Windows Server NFS share. I tried using the command below but got an error message about wrong fs type.

Question 1: Guessing I need install cifs-utils for that to work?
Question 2: What other options are there to mount this Windows share on my CentOS box instead of using cifs-utils?

[splunk@Server321 windows]$ sudo mount -t cifs -o user=user123 //10.10.70.174/share /mnt/windows
mount: wrong fs type, bad option, bad superblock on //10.10.70.174/share,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)

In some cases useful info is found in syslog - try
dmesg | tail or so.

1. Windows does not do NFS as a native service, you would have to load special software to present as NFS. Windows presents a share using SMB (older) or CIFS (newer). If you attempt something that either server does not support you will have problems.

2. Is your share offered using the native windows tools?
If it is, then something like smbclient from the samba package tools should work. It allows you to transfer to and from cifs/smb shares like you were using an ftp or sftp command-line file transfer tool. This does NOT require that it be mounted, but it DOES require that you have the path, authentication, server, and other options correct.

3. If you really want to mount it like that, did you check if you need the user password on the command line?

4. Did you try the mount.cifs tool as described in the messages?

5. did you check your syslog messages in /var/log and see if it looked additional information?

Did you install cifs-utils? Since you asked, the quick answer would be to try it and the package information would suggest that this maybe needed.

Code:

# yum info cifs-utils
...

In addition, if running a desktop you should be able to use the file browser to browse and access windows shares without installing cifs-utils

My sysadmin told me that they loaded NFS on that Windows file server for those shares. With that being said, I could use either NFS or CIFS correct? Also, I would have to install either nfs-utils or the smbclient on the CentOS server correct? I like the idea of not having to mount the share so I may test out the smbclient method. Any advantage of using the NFS-UTILS over CIFS and smbclient?

Hey guys thanks for your help I went with the NFS client install app and all is working now.

You clearly no longer need this information now, but the answer is "no". There is no forces relation between NFS shares and CIFS shares, so they will only match if the admin forced it that way.

I am very glad your problem is solved. Thank you for the interesting thread.
