|Free Software at Schools: Installing and Maintaining a Skolelinux/Debian-edu Network; Based on Debian Sarge, prerelease pr05|
|Prev||Chapter 3. Firewall/Router for Skolelinux/Debian-edu||Next|
Coyote Linux has a nice and well-functioning web administrator that lets you perform almost all day-to-day operations. Point your web browser to the address http://10.0.2.1:8180
At this address you will be met by the Coyote Linux web administrator. Click on the link, and then write in the username root and the password you made, refer to Figure 3-15
All options and choices are done in the Main Menu to the left.
Choosing this will give you the status of your network cards, the IP addresses they have, uptime of Coyote Linux, load and such.
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.
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
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
Here you can enable/disable services such as DNS, SSH, webadmin.
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 10.0.2.2 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.
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.
Advanced Firewall Configuration<
Here you can setup bandwidth limitations
Here you can change the root password, also known as the system password in Coyote Linux, just like you did using the command line in Section 3.6.
This is the files that contains all your configurations.
Here you have useful tools, such as ping, gateway test, DNS server test, status of network.
If you have made any changes in Coyote Linux, then you must remember to write them to floppy, by choosing this Main Menu item, otherwise your changes will be gone when you reboot Coyote Linux. There is a red warning at the bottom of the screen whenever you make changes to Coyote Linux without having them written to the floppy.
When you need to reboot Coyote Linux, you can do so from this Main Menu item. You will have to reconfirm this option.
