Recently I got an online job and I need to connect to their VPN. I got it done on Windows laptop by installing Shrew Soft VPN client (I know it's old, it's what they told me to use). Going to my Ubuntu Desktop, I tried using the settings software for VPN but now I'm stuck.
On Windows, I needed to input the Server Address (of course), the group name, and the pre-shared key. I do not see where I can put anything but the server address in either OpenVPN or PPTP options in Ubuntu. I don't have a certificate yet, but on Windows I didn't need it immediately. (Says I must get a key like a week later.)
To try to bypass this, I tried installing Shrew VPN onto Ubuntu. I downloaded the .tgz file from their website and used the tar command to unpack it, now I have no idea what to do with the file to run the application.
I need help either figuring out how to run the file I just un-packed or working with Ubuntu's VPN services to connect to this VPN.
