Opening a IBM SoftLayer VPN Connection from the Linux command-line

If you need to open a VPN connections to Softlayers private network, you should do this via a browser, as described at http://knowledgelayer.softlayer.com/procedure/ssl-vpn-connections. From what I experienced, with Linux you would need to run a browser as root to follow the instructions.
Fortunately, there is another way: The command-line client. Using that is rather straight forward (except one gotcha).
1. Download the VPN software from http://speedtest.dal05.softlayer.com/array/ArrayNetworksL3VPN_LINUX.zip
2. Rename the zip file to bin (I tried to uncompress it, which failed miserably)
mv ArrayNetworksL3VPN_LINUX.zip ArrayNetworksL3VPN_LINUX.bin
3. Make the file executable
chmod 777 ArrayNetworksL3VPN_LINUX.bin
4. Execute it as root
And your are done.
Now you can open up a VPN connections to Softlayer from the comfort of your command-line:
sudo /usr/local/array_vpn/array_vpnc -hostname https://vpn.ams01.softlayer.com -username [YOUR SOFTLAYER USERNAME] -passwd '[SUPER_SECRET PASSWORD]' &
Which should give you a
array_vpnc: VPN TUNNEL SUCCESSFUL!message back.
A quick "ifconfig tun[x]" should also show a valid 10.a.b.c Softlayer IP adresss.

If you can also successfully ping 10.0.80.11 or your server's private address, you are successfully connected.
ping -c 3 10.0.80.11

Pro-tip: Use the VPN server of the Softlayer datacenter where your machines reside. Apparently, there exists at least one Softlayer VPN Server for every datacenter:
- https://vpn.dal01.softlayer.com for Dallas, Texas, USA
- https://vpn.sea01.softlayer.com for Seattle, Washington, USA
- https://vpn.wdc01.softlayer.com for Washington, D.C., USA
- https://vpn.ams01.softlayer.com for Amsterdam, The Netherlands, Europe
- and so on ...
I must say, that I was pleasantly surprised (again) by Softlayers support. I had a correct answer to my question in under 5 minutes after opening the ticket.
