 |
|
Hi,
I am mounting multiple network filesystems via cifs. The servers that are hosting the shares are part of a domain and require proper authentication. Here is what my /etc/fstab looks like.
| Code: | //192.168.110.10/Share /mnt/sites/Server1 cifs credentials=/root/credentials 0 0
//192.168.105.10/Share /mnt/sites/Server2 cifs credentials=/root/credentials 0 0 |
The file systems mount perfectly using a credentials file that looks like this.
| Code: | username=user
password=pass |
Is there a good way to encrypt the credentials file so that i no longer have this plain text file sitting around with domain login info in it 
Thanks! |

skarecrow,
You can place the credentials file on an encrypted loopback filesystem. But then you've got the key for your encrypted filesystem in plaintext. Also, you still have to mount that encrypted filesystem (which decrypts it) to access the file. However, you could have a script mount the encrypted fs prior to mounting the shares, then unmount it once the shares are mounted.
see man losetup for details.

p.s.- This probably isn't the only way (or even the best way) to encrypt this information. It was just the first one to come to mind... |
