PREFACE
This document describes what yet has to be done in NET-2, how to install
it, and more of that stuff.
NEWS
New items in the Rev.C and Rev.D releases of NET-2:
- Many small improvements in the protocol modules. ICMP still has some
problems, though.
- The ARP problems have been fixed. This means, that ARP no longer listens
to all incoming ARP packets, but only to those requesting one of our own
addresses. This saves on memory, which some of us don't have much of.
Also, ARP no longer tries to request an address 'for ever', which caused
quite some broadcast storms on real networks. ARP now maintains a count
of how many times it tried to get an address for a packet. If 3 tries
occurred with no reply, ARP simply discards the packet.
The ARP dumping code has been changed to watch the 4Kbyte limit of the
PROCfs buffers. This caused machines to crash on large ARP tables.
- many, many small fixes like those in the Makefiles. You all know what
I am talking about here.
- The D-Link Pocket Ethernet Adaptor driver has been added to the stan-
dard distribution, and the DP8390 driver kit has been updated. All
problems related to the drivers should be fixed now.
- The old "WE" driver for the WD8013 has been removed. We no longer
use it, sooo...
- Again, new driver patches from Donald Becker are patched in.
- UDP now handles broadcasts correctly.
- Kernel stalls and TCP freezes should be fixed now. Thanks to Corey
Minyard.
- Some fixes have been applied to the UNIX domain code.
- New code from Fred Baumgarten and Gerald Heim has been added, for the
new-style netstat(8) package.
- The SLIP driver has been fixed, and works fine now.
- Much changes in the interface to the IP routing table, to be more
compatible with BSD UNIX. We can now run BSD routed(8).
- The NET base utils (release 0.09) is needed for this version of the
NET-2 kernel layer.
BUGS
Several known bugs remain:
- no IP fragmentation yet. We need 'mbuf's for that, on which work is
already being done. Will be after Linux 1.0, alas.
- for the same reason: DDI is not finished yet.
- No IP Option Processing yet. Partly because I don't yet feel like
it...
INSTALLATION
1. Create a source directory called /usr/src/linux, and unpack
the standard kernel source there.
2. Remove the old NET code with the commands:
# rm -rf /usr/src/linux/net
3. Remove two old include files:
# rm -f /usr/src/linux/include/linux/socket.h
# rm -f /usr/src/linux/include/linux/sock_ioctl.h
4. Unpack the "net-kernel.tgz" file:
# cd /usr/src/linux
# tar xfvz /tmp/net-kernel.tgz
This contains the new NET code plus patches to the rest of
the kernel. Also note, that this archive overwrites any
current "Makefile", "config.in" or "Configure" files in the
top-level directory.
5. Make config && depend:
# cd /usr/src/linux
# make config
# make depend
Choose the "TCP/IP Networking software version 2" in the
configuration section.
6. Make the kernel.
NETWORK PROGRAMS
NET-2 has changed a lot, so a new set of "base utilities" comes with
it. These programs allow you to set up and maintain your network.
To compile and install:
1. Create the directory:
# mkdir /usr/src/commands/usr.net/net
2. Unpack the distribution:
# cd /usr/src/commands/usr.net/net
# tar xfvz /tmp/net-base.tgz
3. Make the stuff.
# make
Here is how I have things set up here:

Note, that in LINUX/Pro, all system config files are kept in /conf, and
all non-needed binaries (like the TCP/IP and RPC servers) are in /usr/etc.
Have a look at the sample config files in the net-base distribution, and
pay close attention to the "rc.inet[12]" files, which set up your network.
SLIP
For SLIP users: yes, SLIP works. Have a look at the new "dip" program
and its config file. Dip is not perfect yet, but I am sure the guys
at Demon.Co.Uk will change this. Right, guys? :-)
