[SOLVED] How can I mount a remote Location in Fstab with RW permission?

jokar.mohsen · 10-28-2014, 11:38 AM

Hello All.
I use Debian 7 x64 and want to mount a Windows partition in fstab with RW permission. I use below command in fstab but it is Read-Only !!!!

//192.168.1.1/D$ /mnt/f cifs username=test,dom=Mydomain,password=XxX,rw 0 0

it show me :
mount: block device //192.168.1.1/D$ is write-protected, mounting read-only

How can I solve it?

I have not done this myself, but I would be reaching for Samba and/or NFS to do so.

Samba is for sharing a Linux filesystem with a Windows client
NFS is for sharing a Linux filesystem with a Linux client

Neither are what the OP is looking for. He wants CIFS, which is what he's using.

OP - my guess is the user and password you've provided for the share do not have write permissions on the Windows box. Remember, this should be the username and password for a Windows user who has write permission on the specified drive, not your Linux user/pass.

You should also make sure the mount point "/mnt/f" has the proper permissions. And it would be a good idea to put your user/pass in a special file that's only accessible by root and is referenced using the credentials argument in fstab, otherwise your Windows user/pass will be available in plain-text to literally anybody who logs into your Linux system.

FWIW - here is the fstab entry on my machine for a Windows mount with read permission for everybody and read/write permission for all members of the "source" group.

Code:

//192.168.1.118/shared	/home/shared	cifs	auto,gid=source,file_mode=0664,dir_mode=0775,iocharset=iso8859-15,credentials=/etc/sambapasswords 0 0

and the /etc/sambapasswords file:

Code:

# ls -l /etc/sambapasswords
-rw------- 1 root root 42 Aug  5  2011 /etc/sambapasswords
# cat /etc/sambapasswords
username = myuser
password = mypass

Thank you.
Make a File for username and Password is a good idea and I will do it.
About the username and password I must tell you that this Username is admin and have full permission. When I use "Connect to server" and select "Windows share" in "Type" part and use this Username, I have full permission.
What is your Idea? my "/mnt/f" directory have :

"drwxr-xr-x 1 root root 12288 Sep 20 17:10 f"

????

Try changing the group of the mount point to some group your main users are a part of (eg: users) and give the group write permission, and in the mount set the gid, file_mode, and dir_mode to give the group read/write permission.

Hi.
I change the directory owner via below command :

chown -R mohsen:mohsen f/

and ls -l show :

drwxr-xr-x 2 mohsen mohsen 4096 Aug 9 21:29 f

but I can't create file and directories!!! Excuse me, I created "f" directory under the "/mnt" , Must I change "mnt" directory owner too?

about "/etc/sambapasswords" , I have not this file, Can I create it manually?

Thanks.

Any Idea?

Yes create the /etc/sambapasswords file, you can name it whatever you want, doesn't matter.

Did you add the gid, file_mode, and dir_mode options from my example? That mounts it with a specific group and lets you modify the permissions appropriately so members of that group can have write access.
