Doing some searching I found a lot of bad advice, and a lot of methods that proved to be a little convoluted. So I thought I would post a method here.
This assumes you have admin priviliges on your Linux system. It also assumes you wish to provide full access to the share for yourself, but not for other users. However, with this startingpoint and a little reading of man pages it should be fairly self-explanatory how to proceed if you need a slightly different result.
On your Linkstation, set up a user with RW access to all of the shares that you want to mount on your linux system. I recommend even setting up a user for shares that don't require a user. It just makes things more uniform when you're setting up several shares on your Linux box.
Now on your linux system:
First, in your /mnt directory create a folder named /mnt/lspro. (You may use a different name if you wish, but be consistant.)
These are the variables you'll need to adapt for your situation:
LSIP = IP address of your Linkstation
SHARE = Share name (case sensitive)
LSUSER = Linkstation share username.
LSPASS = Linkstation share password.
USER = Your Linux account username.
sudo mount -t cifs //LSIP/SHARE /mnt/lspro/SHARE -o username=LSUSER,password=LSPASS,uid=USER,file_mode=0644,dmode=0755
I repeated the above for each of my shares that I wanted to be able to access from my Linux system.
Sudo will be asking you for your Linux account password. Once this is done, you'll have your Linkstation share available at /mnt/lspro/SHARE (where SHARE is whatever name you gave it). Now, it may be inconvenient for you to dive into /mnt/lspro to find your Linkstation files, so in your home directory do this:
ln -s /mnt/lspro
Now you'll have a symbolic link that looks like a directory in your home directory called lspro. Inside it, you'll have all the shares you mounted.
