I'm planning to move to ubuntu from windows, but I don't know how to configure VPN in ubuntu.

On windows, the VPN provider has provided a GUI application, I just need to input my username and password, then choose a server in a list, everything is done.

But I input the same information into ubuntu, in the following dialog:


But it can't connect to server, the error message is:


(PS: I'm running the ubuntu in Virual-Box with default settings, and the type should be PPTP)

How to configure it correctly?

First, find out the VPN type. Cisco? OpenVPN? PPTP? IPsec? – grawity Aug 29 '11 at 13:25
Thank you. It's PPTP – Freewind Aug 29 '11 at 13:37

Without knowing the exact specifics of your VPN server, I can't really say for sure.

However, if it is a Windows VPN server you are connecting to (PPTP) I wrote a blog post about it... Click Here to read

Basically, go to your Windows box and try to copy all the settings you can find, in particular the security/encryption details.

If you are using a Windows VPN, here are the pictures from my blog post on how I set up Ubuntu to connect to my VPN server:

Thank you, but unfortunately, it doesn't work for me, still can't connect. Do you know how to see the detailed log? – Freewind Aug 29 '11 at 14:09
@Freewind Do you have access to the VPN server? – William Hilsum Aug 29 '11 at 14:14
Check your logs - sometimes you'll get more information from them about what the failure is. – Broam Aug 29 '11 at 14:20
@Broam, I'm not familiar with ubuntu, could you tell me how to check the logs? Where is the log file? – Freewind Aug 29 '11 at 14:33
System -> Administration -> Log File Viewer if you want graphical. If you want to browse the files yourself, check /var/log – Broam Aug 29 '11 at 17:03

You might want to try ensuring that "Allow Stateful Encryption" is checked (in addition to the above screenshot settings)
