accessing files from various types of media nice and abstracted away from the wet-work involved in preparing, validating, and initializing those types of media. This will be used for the package management system module and other modules that need access to files and want to allow the user to decide where those files come from (either in a scripted fashion, prompted fashion, or any combination thereof). Heavily inspired by sysinstall and even uses the same reserved words so that scripts are portable. Coded over months, tested continuously through- out, and reviewed several times. Some notes about the changes: - Move network-setting acquisition/validation routines to media/tcpip.subr - The options screen from sysinstall has been converted to a dialog menu - The "UFS" media choice is renamed to "Directory" to reflect how sysinstall treats the choice and a new [true] "UFS" media choice has been added that acts on real UFS partitions (such as external disks with disklabels). - Many more help files have been resurrected from sysinstall (I noticed that some of the content seems a bit dated; I gave them a once-over but they could really use an update). - A total of 10 media choices are presented (via mediaGetType) including: CD/DVD, FTP, FTP Passive, HTTP Proxy, Directory, NFS, DOS, UFS, Floppy, USB - Novel struct/device management layer for managing the issue of passing more information than can comfortably fit in an argument list.

You can do network installations over 3 types of communications links:
|
|
|
|
Serial port: SLIP / PPP
|
|
Parallel port: PLIP (laplink cable)
|
|
Ethernet: A standard Ethernet controller (includes some
|
|
PCMCIA networking cards).
|
|
|
|
SLIP support is rather primitive and limited primarily to directly
|
|
connected links, such as a serial cable running between a laptop
|
|
computer and another PC. The link must be hard-wired as the SLIP
|
|
installation doesn't currently offer a dialing capability (that
|
|
facility is offered by the PPP utility, which should be used in
|
|
preference to SLIP whenever possible). When you choose the SLIP
|
|
option, you'll be given the option of later editing the slattach
|
|
command before it's run on the serial line. It is expected that
|
|
you'll run slattach (or some equivalent command) on the other end of
|
|
the link at that time and bring up the line. FreeBSD will then
|
|
install itself at serial speeds of up to 115.2K/baud (the recommended
|
|
speed for a hardwired cable).
|
|
|
|
If you're using a modem then PPP is almost certainly your only choice.
|
|
Make sure that you have your service provider's information handy as
|
|
you'll need to know it fairly early in the installation process. You
|
|
will need to know your service provider's IP address, the IP address
|
|
of your provider's DNS server, and possibly your own IP address unless
|
|
your ISP supports dynamic negotiation, most do. If you do not choose
|
|
a PAP or CHAP login you will also need to know how to use the various
|
|
"AT commands" to dial the ISP with your particular brand of modem as
|
|
the PPP dialer provides only a very simple terminal emulator and has no
|
|
"modem capabilities database". If you choose a PAP or CHAP login you
|
|
can simply enter `dial' (without the quotes) at the ppp prompt if your
|
|
modem uses the Hayes compatible AT command set.
|
|
|
|
If a hard-wired connection to another FreeBSD (2.0R or later) machine
|
|
is available, you might also consider installing over a "laplink"
|
|
parallel port cable. The data rate over the parallel port is much
|
|
higher than what is typically possible over a serial line, and speeds
|
|
of over 50KB/sec are not uncommon.
|
|
|
|
Finally, for the fastest possible network installation, an Ethernet
|
|
adaptor is always a good choice! FreeBSD supports most common PC
|
|
Ethernet cards, a table of which is provided in the FreeBSD Hardware
|
|
Guide (see the `Documentation' entry in the main menu). If you are
|
|
using one of the supported PCMCIA Ethernet cards, also be sure that
|
|
it's plugged in BEFORE the laptop is powered on! Sysinstall does not,
|
|
unfortunately, currently support "hot insertion" of PCMCIA cards.
|
|
|
|
You will also need to know your IP address on the network, the
|
|
"netmask" value for your address class, and the name of your machine.
|
|
Your system administrator can tell you which values to use for your
|
|
particular network setup. If you will be referring to other hosts by
|
|
name rather than IP address, you'll also need a name server and
|
|
possibly the address of a gateway (if you're using PPP, it's your
|
|
provider's IP address) to use in talking to it. If you do not know
|
|
the answers to all or most of these questions then you should really
|
|
probably talk to your system administrator FIRST before trying this
|
|
type of installation! Choosing the wrong IP address on a busy network
|
|
will NOT make you popular with your systems administrator! :-)
