Ubuntu: VPN to specific organization


I have a question about VPN in ubuntu 15.10. I want to connect a VPN of Lund university, Sweden. What I have are: my user-name and the password Also I'm able to configure the VPN from the network manager, I already connected to another VPN, but I have the three files ca.crt, certificate.crt and key.key, They are general files so I can use to connect to that VPN? Also I don't know what's the gateway, it can be connect.lu.se?

At least I wanna know How can I connect to Lund university using my user-name and password, which I used on windows8. Below you can find an explanation of what I do.

The right part shows the main network manager window to create the VPN and the left 4 small windows show the advanced options. In order to get the free vpn work, I write the gateway, user-name,password and the three certificate files downloaded, then I go to the advanced options. First tab (General) I put the port to 443, mark on use LZO compression and use TCP. Second tab just put Cipher to AES_128-CBC

Thanks, Elsaid


Run this:

sudo apt-get install openvpn  

To install the OpenVPN package. Then, make a new file in your home directory, client.conf. Edit that file to contain the following:

# Specify that we are a client and that we  # will be pulling certain config file directives  # from the server.  client    # Use the same setting as you are using on  # the server.  # On most systems, the VPN will not function  # unless you partially or fully disable  # the firewall for the TUN/TAP interface.  ;dev tap  dev tun    # Windows needs the TAP-Win32 adapter name  # from the Network Connections panel  # if you have more than one.  On XP SP2,  # you may need to disable the firewall  # for the TAP adapter.  ;dev-node MyTap    # Are we connecting to a TCP or  # UDP server?  Use the same setting as  # on the server.  ;proto tcp  proto udp    # The hostname/IP and port of the server.  # You can have multiple remote entries  # to load balance between the servers.  remote connect.lu.se 1194  ;remote my-server-2 1194    # Choose a random host from the remote  # list for load-balancing.  Otherwise  # try hosts in the order specified.  ;remote-random    # Keep trying indefinitely to resolve the  # host name of the OpenVPN server.  Very useful  # on machines which are not permanently connected  # to the internet such as laptops.  resolv-retry infinite    # Most clients don't need to bind to  # a specific local port number.  nobind    # Downgrade privileges after initialization (non-Windows only)  ;user nobody  ;group nogroup    # Try to preserve some state across restarts.  persist-key  persist-tun    # If you are connecting through an  # HTTP proxy to reach the actual OpenVPN  # server, put the proxy server/IP and  # port number here.  See the man page  # if your proxy server requires  # authentication.  ;http-proxy-retry # retry on connection failures  ;http-proxy [proxy server] [proxy port #]    # Wireless networks often produce a lot  # of duplicate packets.  Set this flag  # to silence duplicate packet warnings.  ;mute-replay-warnings    # SSL/TLS parms.  # See the server config file for more  # description.  It's best to use  # a separate .crt/.key file pair  # for each client.  A single ca  # file can be used for all clients.  ca ca.crt  cert certificate.crt  key client.key    # Verify server certificate by checking  # that the certicate has the nsCertType  # field set to "server".  This is an  # important precaution to protect against  # a potential attack discussed here:  #  http://openvpn.net/howto.html#mitm  #  # To use this feature, you will need to generate  # your server certificates with the nsCertType  # field set to "server".  The build-key-server  # script in the easy-rsa folder will do this.  ns-cert-type server    # If a tls-auth key is used on the server  # then every client must also have the key.  ;tls-auth ta.key 1    # Select a cryptographic cipher.  # If the cipher option is used on the server  # then you must also specify it here.  ;cipher x    # Enable compression on the VPN link.  # Don't enable this unless it is also  # enabled in the server config file.  comp-lzo    # Set log file verbosity.  verb 3    # Silence repeating messages  ;mute 20  

This is a generic client config file for OpenVPN. Now, to connect, run the following command from your home directory:

sudo openvpn client.conf  

To connect using your given config file.
