Obtain an ISO image from www.ipcop.org. The size of this image is about 50 megabytes. You should check the MD5 checksum of the file you downloaded against the one on the IPCop web site before going any further.
There are many possible ways to install IPCop. The following table summarizes the requirements for each.
Table 1.2. Media required for different installation methods
| Method | Boot Floppy | Driver Floppy | CD Drive | FTP/Web Server | Netcard w/PXE | DHCP/TFTP Server |
|---|---|---|---|---|---|---|
| Bootable CD | N | N | Y | N | N | N |
| Bootable Floppy with CD | Y | N | Y | N | N | N |
| Bootable Floppy with FTP/Web Server | Y | Y | N | Y | N | N |
| Bootable Floppy with usb key | Y | N | N | Y | N | N |
| PXE boot with FTP/Web Server | N | N | N | Y | Y | Y |
If the IPCop PC has a CD drive and its BIOS can boot from CD, you can use the “Bootable CD” media for the install. The CD drive can be removed after the install.
If the IPCop PC cannot boot from CD, but has both a floppy drive and a CD drive, the “Bootable Floppy With CD” can be used. Both the floppy drive and CD drive can be removed after the install. However, if you plan on using IPCop's backup and restore facilities, you may want to keep the floppy disk in the IPCop PC.
Finally, if the IPCop PC has only a floppy drive or you do not own a CD burner, the “Bootable Floppy with FTP/Web Server” must be used. Again, the floppy drive can be removed after the install. Again, if you plan on using IPCop's backup and restore facilities, you may want to keep the floppy drive in the IPCop PC.
If you have a CD burner, use your favorite CD writer package to transfer the ISO image to a CD-ROM. Be aware that the IPCop CD image is a full CD image. In many CD writer software packages, it can be difficult to find the “Burn CD From ISO or Disk Image” option. The option may not be placed under the obvious menu. If you wind up with only one file on the CD, you have not created the CD correctly.
If you don't have a CD writer, have no fear. You can still install IPCop, but you will have to go through some extra work. What has to be done depends upon the hardware and operating systems you have available on other computers.
If you have a Linux or Unix system, you can mount the CD image, using the following commands:
#losetup /dev/loop0 /path/to/IPCop/iso
where
/path/to/IPCop/iso
is the file name of IPCop's
iso
file.
This links a “loop back” hardware
level device to the IPCop ISO file.
#mount -r -t iso9660 /dev/loop0 /mnt/cdrom
This actually mounts the loop back hardware device on a *nix
file system.
The CD-ROM image will appear at
/mnt/cdrom.
NOTE: On most systems you must have root authority
or use the
sudo
command to mount file systems.
There are several utilities such as ISOBuster and WinImage available on the Internet that can be used to open the ISO image. Download one of them, and follow their directions to open the IPCop ISO file.
On Macintosh OS X, Apple's Disk Copy utility will open the ISO image. There does not seem to be a free or public domain utility available to open IPCop's ISO images on Mac systems before OS X. However, many commercial CD-ROM burning programs do have this capability. If you have a CD burner, check the software that came with it.
If your IPCop PC has a CD-ROM, but your BIOS will
not allow a CD-ROM boot, you will need to create a
floppy boot disk.
If your IPCop PC does not have a CD-ROM, you will
need to create both the floppy boot disk and the
driver floppy disk.
Both images reside in the
/images
directory on the ISO image.
On Linux, Unix and Macintosh OS X systems, creating the floppies can be done from a terminal window with the dd command:
#dd if=/mnt/cdrom/images/boot-1.4.0.img of=/dev/fd0 bs=1k count=1440
Use the same command with
if=
pointing to the driver
disk image to create the driver floppy, if needed.
Two utilities are provided in the
/dosutils
directory on the CD and its ISO image.
These are
rawrite.exe
and
rawwritewin.exe.
rawrite.exe
is a DOS based command that can be used to create
floppies from the
.img
files in the
/images
directory.
Similarly,
rawwritewin.exe
is a windows executable that you can run under
Windows to create the floppy disks from the disk
images on the CD.
This step is only needed if you are installing from
bootable floppy and FTP/Web Server.
In the root directory
/
of the ISO image there is a file named
ipcop-1.4.0.tgz.
This file contains a compressed image of the IPCop
hard drive.
Copy this file to a machine that is running a web
server or FTP server.
Put it where the server can find it during install.
During the install, IPCop will log in to your FTP or
web server as anonymous.
Most servers do not allow anonymous users to access
files out of the server's hierarchy.
Even though a directory appears at the top level of
the server, such as
/pub
they really are somewhere else, such as
/anonftp/pub.
If your IPCop PC uses SCSI disk drives then you also need to
copy the file
scsidrv-1.4.0.img
from the
/images
folder of the ISO image to this directory.
If you are creating your private network for the first time, change the IP address of the server machine to be on the private, GREEN, network, using a static address. You only need to do this for the duration of the install.
If your server machine is connected to the Internet, remove the connection and physically connect your IPCop PC and other machines together. See Appendix A, for a discussion of your choices. If you are using 192.168.1.1 for the IPCop PC, 192.168.1.2 is a good address for the server. Set the server up with a static IP address, temporarily. You will need to reboot any Windows PC if you change its IP address.
Verify that the IPCop installation file is available via the FTP command or entering its URL from a browser, even if you have to do it from the server machine. You can cancel the download or close your browser once you are sure the URL works.
