On my laptop I wanted to mount some shared directories (via samba), located on my office network and accessible trough OpenVPN. I need them to work remotely (there is in my office local development server, used from all my colleagues). Connecting to the VPN and mounting the shares was straightforward. I just have had to install smbfs (Samba file system utilities) and put the following line in my /etc/fstab:
//192.168.91.1/deals /mnt/deals-old cifs credentials=/etc/samba/deals-user,noexec,noperm 0 0
