how to use a credential file when mounting a samba share using mount command?

Question

So I often use this command to mount a Samba share.

mount -t cifs //ip/share /mnt/backups -o username=user,password=pwd,domain=domain

I want to use a credentials file (with 600 permission) instead of typing in username/password.

Any ideas how this can be done? I've looked around and the only examples I've found are for using a credentials file if I want to auto-mount a Samba share using /etc/fstab.

Thanks

Answer 1

you must use the argument credentials=

mount -t cifs //ip/share /mnt/backups -o credentials=/path/filename

quoting from man mount.cifs

credentials=filename

specifies a file that contains a username and/or password and optionally the name of the workgroup. The format of the file is:

username=value
password=value
domain=value

I suggest to create your file under /root/.smbcredentials_sharename with permission 600 as you already said.

Make sure NOT to have spaces around the = or you will get permission denied errors as the values are not correctly taken into account.
