  1. Information

    Choosing this will give you the status of your network cards, the IP addresses they have, uptime of Coyote Linux, load and such.

  2. LAN configuration

    Here you have the option of changing the configuration of the LAN network card, the one that goes to the Skolelinux/Debian-edu network.


    Don't change anything here! Doing so will severely reduce the performance of your Skolelinux/Debian-edu network.


    Should parse the contents of change_ip_setup in here, later.

    Leave the values as they are, refer to A.

  3. Internet configuration

    Here you have the chance of changing the values of your WAN network card, the one that goes to Internet. If you get a new ISP, or go from getting your IP address assigned by DHCP to having a static IP address, then this is the place to change that kind of information with no need for creating a new Coyote Linux floppy from scratch. See 2.b

  4. DHCP configuration

    This gives you the chance to configure the DHCP-server that comes with Coyote Linux.


    Do not enable the DHCP-server in Coyote Linux! See 2.h

  5. Administrative Configurations

    Here you can enable/disable services such as DNS, SSH, webadmin.

  6. Port Forwarding

    Here you can change and enable port forwarding on Coyote Linux. This is a very practical and neat feature in a Skolelinux/Debian-edu network. Since Coyote Linux stops and blocks most connections, even passing SSH, it's nice to be able to use port forwarding and that way still get past Coyote Linux with incoming SSH-connection to the Skolelinux/Debian-edu network.

    With this port forwarding rule

Yes 	TCP 	Any 	22 	22 	No 	  SSH straight into Mainserver

    all SSH-connections coming to Coyote Linux will be redirected to the Skolelinux/Debian-edu main server. If this is advisable in your network, you must decide.

  7. Simplified Firewall Configuration

    Here you can setup and configure the firewall rules in Coyote Linux. There are plenty of ready-made rules that you can use as examples.

  12. Diagnostic tools

    Here you have useful tools, such as ping, gateway test, DNS server test, status of network.
