| - | ===== :!: WIP :!: LUVPN on OpenSuSE 15.1 :!: WIP :!: ===== | + | Sometimes when restarting networking the icon on the upper right corner shows that you're disconnected, and the VPN will not connect any longer. It is a gnome3 bug that affects network manager. To solve, it is enough to restart gnome3 by doing the following: |
| + | |||
| + | - Press ''Alt'' and ''F2'' | ||
| + | - In the dialog that appears, type ''r'' and press enter | ||
| + | |||
| + | The icon should be restored. | ||

| + | - Configure the VPN as shown in the figure, then click Save. {{ :it_tips:luvpn_os15_configvpn.png |}} | ||
| + | - The VPN is now listed in the network manager. Click OK. {{ :it_tips:luvpn_os15_vpndone.png |}} | ||
| + | |||
| + | ==== Connecting to the VPN ==== | ||
| + | |||
| + | - In order to **connect**, click on the small computer icon in the lower right corner, identify the VPN network and click on "Connect" {{ :it_tips:luvpn_os15_vpnconnect.png |}} | ||
| + | - You may be prompted for your LUCAT password. If all goes well, you should see this icon in the lower left corner: {{ :it_tips:luvpn_os15_connected.png?600 |}} | ||
| + | - The connection is now established, however it is not very secure. You may need to configure IPsec to encrypt it, see later in this document. | ||
| + | |||
| + | ==== Disconnect from the VPN ==== | ||
| + | - To **disconnect**, open the network manager icon again and click "**Disconnect**" | ||
| + | - Sometimes the applications do not react well after a vpn disconnect. Restarting NetworkManager doesn't help in openSuSE, it just messes up with its configuration. The best is to close and reopen the application or logout and relogin. | ||
| + | |||
| + | ==== ::WIP:: Enabling IPsec ::WIP:: ==== | ||
| + | |||
| + | Unfortunately at the moment I did not manage to make IPsec work with OpenSuSE. Something is broken in the networkmanager configuration that does not pass the options to the services. In principle it should be enough to configure the IPsec options in the VPN dialog as below: {{ :it_tips:luvpn_os15_vpnipsec.png |}} | ||
| + | |||
| + | But it does not work. | ||
