|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|
This chapter should be moved to after the introductions to available commands in Coyote Linux
Coyote Linux is a product that is in active development and maintenance, just like Skolelinux/Debian-edu. That means that new versions are released quite often, with new features and security fixes. Especially because of the security fixes, you should always use the latest stable version of Coyote Linux
Since Coyote Linux runs solely from floppy, there is no system, per se, to upgrade. You must create a totally new floppy, as in Section 3.3. To make this process as easy as possible, there are some simple things to keep in mind.
Finding out what kind of network cards you have: If you have forgotten what kind of network cards you use and didn't write it down somewhere, then you can use the command lsmod to list all loaded driver modules that are in use. Maybe that way you'll remember which network cards you have.
coyote# lsmod Module Size Used by 3c509 7732 2 ip_nat_quake3 1768 0 (unused) ip_nat_mms 2608 0 (unused) ip_nat_h323 2060 0 (unused) ip_nat_amanda 876 0 (unused) ip_nat_irc 1904 0 (unused) ip_nat_ftp 2384 0 (unused) ip_conntrack_quake3 1848 1 ip_conntrack_mms 2704 1 ip_conntrack_h323 2065 1 ip_conntrack_egg 2280 0 (unused) ip_conntrack_amanda 1488 1 ip_conntrack_irc 2672 1 ip_conntrack_ftp 3440 1
In this listing of loaded modules you see that the network card 3Com509 is in use, twice. For a list of supported modules, look in Section 3.12
It would be best to write down somewhere what network cards you use in the machine.
What kind of port forwarding do you have?
Information about your port forwarding rules, if you have made any, is in the file /etc/coyote/portforwards
