Automatically connect an Openconnect VPN connection

Question

I installed the network-manager-openconnect package and uses it to login to my Openconnect VPN server. The connection works, except that every time I start the connection a two step dialog box pops up and asks for my VPN username and password:

This is the first dialog which asks for the username. If the username is correct, it'll go to the second dialog and ask for the password.

Is there a way to provide the VPN username and password in a configuration file so that it doesn't ask for it every time? This is important since I'm trying to make this machine headless.

Or alternatively is there a way to have network-manager-openconnect get the username and password from the keyring, and have the keyring be automatically unlocked after login? I'm using Ubuntu 16.04 LTS Beta 2.

Solution

Does openconnect work for you?

If so you can use this to connect automatically:

sudo openconnect SERVER --no-cert-check -u USERNAME --passwd-on-stdin  <PASS_FILE

or

echo PASS | sudo openconnect SERVER --no-cert-check -u USERNAME --passwd-on-stdin

I'm not sure OpenConnect works that way.

If you run 'man network-manager-openconnect' does it display any options such as --passwd-on-stdin where you could use a shell script to echo your username and password into the network-manager-openconnect so it would auto-connect on boot? When I google the package, I don't see it's man page available online.

I'm getting "No manual entry for network-manager-openconnect" unfortunately.

in ubuntu 18.04 openconnect does not have --no-cert-check, any suggestions ?

@MehrdadPedramfar For newer openconnect version after you enter this answer's code, error message give you the cert code. and you can use it.
