Hi Andre,

Apparently the mac filter works with our Chromebooks and iPads but not with our HP laptops and netbooks and other hardware models. I’m not sure why. He just old me that he can’t use that option with our Lubuntu devices.

You might want a Key Manager. It stores the ciphered passwords to use later on... I know there is gnome-keyring for Gnome and kwallet for KDE. I guess it is opitional to use gnome-keyring with network-manager (nm-applet)...

I could not find anything about activating it, googling it I only see people trying to get rid of it on Ubuntu.

Another better way to ensure network security is to apply MAC filter (a list of allowed hardware). Password in this case is optional...

Good morning,

At our school board we have been converting all our older technology to Lubuntu. Our network manager has brought up a problem that he views as a security risk. He is not familiar with Linux and does not really like having these devices on our network.

In Network connections, users are able to access the network connections for the WIFI, click on edit and then click show password to see the credentials used for the WIFI access. In the case where the device belongs to one individual that’s not a problem but we have a many class sets of devices used by many students and we don’t want them to see the WIFI credentials and share them with friends etc..

I know this is probably very simple but is there a way to have the network connections section password protected? In most cases when you try to modify settings and install programs you are prompted for a password.

Any help would be greatly appreciated.
