Basic Configuration of the firewall/router
Regardless if you choose to create the Coyote Linux floppy on a Linux or Windows machine, the following configuration must be used. This also applies to any other firewall/router than Coyote Linux
local network interface:
IP Address: 10.0.2.1 Netmask: 255.255.254.0 Broadcast: 10.0.3.255 Network: 10.0.2.0
Install the Big Pond login software? [y/n]:n
Press "n"
I think this refers to some extra stuff you need if you happen to get net access from the provider Big Pond, but I'm not really sure. Anybody know?
Do you want to enable the Coyote DHCP-server [y/n]: n
Press "n"
![]() | Since Skolelinux/Debian-edu already has a DHCP-server running, you must disable the DHCP-server on your firewall/router, and on any other machines you want to integrate into your Skolelinux/Debian-edu-network. Having two DHCP-servers on the same network usually doesn't work very well. |
After you have downloaded the Coyote Linux source files, you need to unpack them. You must be superuser root to unpack them.
tar zvxf coyote-2.06.tar.gz
cd coyote
./makefloppysh
![]() | If a new version of Coyote Linux exists at the time you read this, then you must replace the version 2.06 in the commands above with the version number you have downloaded. |
When creating a Coyote Linux on a Linux machine, these are the questions asked, and the answers you should give:
Coyote floppy builder script v2.9
Please choose the desired capacity for the created floppy:
1) 1.44MB (Safest and most reliable but may lack space needed for
some options)
2) 1.68MB (Good reliability with extra space) - recommended
3) 1.72MB (Most space but may not work on all systems or with all
diskettes)
Enter selection:2Choose here what is recommended «1.68MB»
Please select the processor type in the destination Coyote Linux system:
Choose «2) 486dx or better (has a math co-processor)» if you use a relatively new machine (newer than 486), if you make the wrong choice here you machine will not boot.
![]() | This question isn't present in newer versions of Coyote Linux, since the support for machines without a math co-processor has been removed |
Please select the type of Internet connection that your system uses. 1) Standard Ethernet Connection 2) PPP over Ethernet Connection 3) PPP Dialup Connection Enter Selection:
Here you would normally choose option 1)
Configuring system for Ethernet based Internet connection. By default, Coyote uses the following settings for the local network interface: IP Address: 192.168.0.1 Netmask: 255.255.255.0 Broadcast: 192.168.0.255 Network: 192.168.0.0 Would you like to change these settings? [Y/N]: y Enter local IP Address [192.168.0.1]: 10.0.2.1 Enter local Netmask [255.255.255.0]: 255.255.254.0 Enter local Broadcast [192.168.0.255]: 10.0.3.255 Enter local network number [192.168.0.0]: 10.0.2.0
These network settings for the local network must be changed, see A
Does your Internet connection get its IP via DHCP? [y/n]:
Answer yes(y) or no(n), according to you network configuration.
If you do not get IP via DHCP, you need to fill in some information:
Please enter the information for your static IP configuration Internet IP Address: Internet Subnet Mask [255.255.255.0]: Internet Broadcast [Enter = Default]: Internet Gateway Address: Domain Name: DNS Server 1: DNS Server 2 (optional):
Enter your DHCP hostname:
Normally you can leave this one blank
Install the Big Pond login software? [y/n]:
I think this refers to some extra stuff you need if you happen to get net access from the provider Big Pond, but I'm not really sure. Anybody know?
Do you want to enable the Coyote DHCP server? [y/n]: n
Here you must answer «n»!
If you don't know what a DMZ is, just answer NO Do you want to configure a De-Militarized Zone? [Y/N]: n
Here can press just «n»
You now need to specify the module name and parameters for your network cards. If you are using PCI or EISA cards, leave the IO and IRQ lines blank. Enter the module name for you local network card:
This is the tricky part, knowing what type of driver modules to use for your network cards; even knowing what type of network cards you have is sometimes difficult. Have a look at Section 3.12 for an overview of available driver modules. Remember to not use the ending .o when writing what driver module to use.
I prefer newer cards from 3Com. Almost all of them use the driver module 3c59x.
Syslog server address:
This you can leave blank.
![]() | It should be possible to use the Skolelinux/Debian-edu mainserver as Syslog server, but I haven't tried this yet. The address to use would then be 10.0.2.2 |
You must now insert a floppy in the machine. Remember to turn the write protection off. The creation of the floppy will take a few minutes.
If you create the floppy on a Windows machine, it's almost the same procedure as with Linux.
This error appears when you click on the wrong Coyote Linux exe-file.
Here you just press 'Next'
Here you must fill in the necessary network information; see A
Filling in the correct values for IP address and Netmask will make Coyote Linux correctly calculate the values for Broadcast address and Network address
Without this password, you can't logon your Coyote Linux machine later, see Section 3.6
Just leave this blank, or have a look at 2.k
Choose whatever is most appropriate for you. If you get a DHCP-assigned address, then it is likely that you will not need to give any more information about your connection.
\ If you have a static address, then fill in the appropriate values here.
\ Do not enable the Coyote Linux DHCP-server. There is already one running on the mainserver
Drag and drop to choose the correct network cards in your Coyote Linux machine.
Place a floppy in the floppy drive, and press 'Next'.
