Stage 1: IPv6-capable PCs

Kernel Configuration:

You should be using the latest 2.2.x kernel - go to http://www.kernel.org to get one You will also need the latest version of modutils.
Enter the following commands as root:

# cd /usr/src
# mkdir tmp
# cd tmp
# tar xvzf /path/linux-2.2.15.tar.gz
# mv linux ../linux-2.2.15
# cd ..
# rm linux
# ln -s linux-2.2.15 linux
# cd linux
# make mrproper

You can now copy your .config file here if you have one. If the .config is from an older kernel, do a make oldconfig. This will update it for this kernel version and prompt you if there are new options Otherwise, you will have to set all of the options manually in the next command.

# make menuconfig

# make dep
# make clean
# make bzImage
# make modules
# make modules_install

Now copy /usr/src/linux/System.map to /boot/System.map-2.2.xx-ipv6 (where 2.2.xx is your kernel version)
Copy /usr/src/linux/arch/i386/boot/bzImage to /boot/vmlinuz-2.2.xx-ipv6
Edit /etc/lilo.conf, adding a new boot selection for the kernel (or if you are brave, set the current boot option to use it)
Now reinitialize your boot sector:

# lilo

Now reboot, remembering to boot with your new kernel

Installation of Required Software:

Thanks to Peter Bieringer (http://www.bieringer.de) for having provided much of this information in his excellent IPv6 HowTo.

net-tools: http://www.tazenda.demon.co.uk/phil/net-tools/net-tools-1.54.tar.gz
Supplies: hostname, netstat, arp, ifconfig, rarp, route

# cd /usr/src
# tar xvzf /path/net-tools-1.54.tar.gz
# cd net-tools-1.54
# make clean
# make config

Does your system support GNU gettext? (say y)
UNIX protocol family? (say y)
INET (TCP/IP) protocol family? (say y)
INET6 (IPv6) protocol family? (say y)
(choose the defaults for the next few by hitting <ENTER>)
SIT (IPv6-inIPv4) support? (say y)
(choose the defaults for the rest)

#make
#make install

iputils: ftp://ftp2.3dgamers.com/pub/mirrors/redhat/ftp.redhat.com/redhat/redhat-6.2/i386/RedHat/RPMS/iputils-20000121-2.i386.rpm
Supplies: arping, clockdiff, ping6, rdisc, tracepath, tracepath6, traceroute6

If you are using RedHat 6.2, you can skip this

# rpm -Uvh /path/iputils-20000121-2.i386.rpm
You may be asked to install other prerequisite packages first
If you get a message about conflicts, you can use the --force option

Netkit: ftp://ftp.suse.com/pub/people/kukuk/ipv6/nkit-0.4.1.tar.gz
Supplies: finger, fingerd, inetd, ping, ping6, telnet, telnetd and IPv4 only ruptime, rwho, rwhod

# cd /usr/src
# tar xvzf /path/nkit-0.4.1.tar.gz
# cd nkit-0.4.1
# ./configure
# make clean
# make
# make install
(note: this overwrites some of the files from iputils (like ping6), but this should be OK)

xinetd: http://synack.net/xinetd/xinetd-2.1.8.8p2.tar.gz
Supplies: xinetd (inetd replacement), itox (converts inetd.conf)

# cd /usr/src
# tar xvzf /path/xinetd-2.1.8.8p2.tar.gz
# cd xinetd-2.1.8.8p2
# ./configure --with-inet6 --with-libwrap
# make clean
# make
# make install
# cat /etc/inetd.conf | itox -daemon_dir /usr/sbin/tcpd >/etc/xinetd.conf
Be sure to follow the instructions in the section "Configuring xinetd" later in this document!

libpcap: http://www.tcpdump.org/daily/libpcap-current.tar.gz
Supplies: libpcap.a (packet capture library; needed by tcpdump)

# cd /usr/src
# tar xvzf /path/libpcap-current.tar.gz
# cd libpcap-<version>
# ./configure --enable-ipv6
# make clean
# make
# make install

tcpdump: http://www.tcpdump.org/daily/tcpdump-current.tar.gz
Supplies: tcpdump (packet capture utility)

# cd /usr/src
# tar xvzf /path/tcpdump-current.tar.gz
# cd tcpdump-<version>
# ./configure --enable-ipv6

You must now apply some fixes before the source will compile (these may already be fixed in later versions).
In Makefile, find the line that says:

INCLS = -I. -I$(srcdir)/missing -I$(srcdir)/linux-include

and append to that line:

-I<path to libpcap source> (for example, append "-I/usr/src/libpcap-20000521")

In print-ppp.c and print-chdlc.c, add the following line before the line that says "#include <ctype.h>"

#include <ethertype.h>

In print-icmp6.c, around line #584, replace the following line:

#error unknown mld6 struct

with:

void

mld6_print(register const u_char *bp)

{

printf("unknown mld6");

}

In print-rt6.c, add the following line to the top of the file:

#define IPV6_RTHDR_TYPE_0 0

Now proceed with the installation:
# make clean
# make
# make install

Apache: http://www.apache.org/dist/apache_1.3.12.tar.gz(needs patch at ftp://ftp.kame.net/pub/kame/misc/apache-1.3.12-v6-20000518.diff.gz)
Supplies: httpd (Apache Web Server)

Note: If you already have an RPM of apache installed, you should install the ipv6 RPM from:
ftp://ftp.jindai.net/pub/linux/ipv6-rpm/glibc21/RPMS/i386/apache-1.3.9-1_v6.i386.rpm
and restart httpd (run "/etc/rc.d/init.d/httpd restart")

Otherwise, do the following:

# cd /usr/src
# tar xvzf /path/apache_1.3.12.tar.gz
# cd apache_1.3.12
# gzip -d <patch-location>/apache-1.3.12-v6-20000518.diff.gz (This may have already been done by FTP)
# patch -p1 < <patch-location>/apache-1.3.12-v6-20000518.diff

Now use the special configure.v6 script to prepare for compilation:
# chmod +x configure.v6
# ./configure.v6 --prefix=<apache install directory>
# make clean
# make
# make install
# /usr/local/apache/bin/apachectl start (You must do this every time you boot)

Now read README.v6 for IPv6 specific changes to configs.

Chimera: ftp://ftp.jindai.net/pub/linux/ipv6-rpm/glibc21/RPMS/i386/chimera-2.0a14-1.i386.rpm
Supplies: Chimera (an IPv6-compatible web browser)

Don't bother trying to compile from the source; the Makefile will need a number of changes to work.
Instead, settle for the RPM:

# rpm -Uvh /path/chimera-2.0a14-1.i386.rpm
# ln -s /usr/inet6/bin/chimera /usr/bin/chimera

Basic configuration:

/etc/protocols: Append new lines with IPv6 protocol numbers if they are not there:

       ipv6       41 IPv6       # IPv6
       ipv6-route 43 IPv6-Route # Routing Header for IPv6
       ipv6-frag 44 IPv6-Frag # Fragment Header for IPv6
       ipv6-crypt 50 IPv6-Crypt # Encryption Header for IPv6
       ipv6-auth 51 IPv6-Auth # Authentication Header for IPv6
       ipv6-icmp 58 IPv6-ICMP icmpv6 icmp6   # ICMP for IPv6
       ipv6-nonxt 59 IPv6-NoNxt # No Next Header for IPv6
       ipv6-opts 60 IPv6-Opts # Destination Options for IPv6

/etc/hosts: Append new lines with special IPv6 addresses if they are not there:

       ::1     ip6-localhost ip6-loopback
       fe00::0 ip6-localnet
       ff00::0 ip6-mcastprefix
       ff02::1 ip6-allnodes
       ff02::2 ip6-allrouters
       ff02::3 ip6-allhosts

Configuring xinetd:

/etc/xinetd.conf must be edited to support the currently installed daemons, if it doesn't already. Look in xinetd/sample.conf for a sample config. Specifically, the paths to your servers are most likely wrong. For example:

/usr/sbin/tcpd/in.telnetd

should be:

/usr/sbin/in.telnetd

...and so on.

Now you will need to start the daemon. First, make sure you have no active connections through inetd, and then:

# killall inetd
# xinetd

After a moment, xinetd will return you to the shell and it will be running in the background. Look at /var/log/messagesto see if there were any errors. You will need to kill inetd and start xinetd manually every time you boot now unless you change your init scripts and rc files to do this for you.

Check that the services are running. Look at the output of the following command for lines with ":::<well-known port>":

# netstat -A inet6 -anp

Now test the server by doing a telnet localhost. You may also need to edit your /etc/hosts.allow and /etc/hosts.deny files if it doesn't work (ie. if you get a "connection refused").
