    Post IPv6 on linuxbox.

    ---=[ IPv6 HowTo on linux ]=---

    - INDEX -[*] Introduction[*] Disclaimer[*] Legal notes[*] How to[*] Appendix[*] Greetings

    - [ INTRODUCTION ] -
    English is not my language (excuse me for errors ),
    although I hope to help you on configuration of IPv6 protocol.
    I have tested this guide on my linuxbox (RedHat 7.2).

    - [ DISCLAIMER ] -
    I am not responsable for crashes or problems on your machine.
    I had tryed to explain all steps, but if you cannot do
    follows operations, please close this file.

    - [ LEGAL NOTES ] -
    You can distribute this document (you must quote me),
    you cannot NEVER receive payment for this How-to.
    (Informations wants be free ...)

    - [ HOW TO ] -
    There are two ways for configure IPv6 protocol on your linuxbox:
    1. Built-in;
    2. Module (option recomended).

    You must see what kernel is used by your linuxbox:

    [root@localhost root]# uname -a
    Linux localhost.localdomain 2.4.7-10 #1 mer mar 13 19:55:33 CET 2002 i686 unknown

    I advise to use a kernel 2.2.* or upper, you can donwload it at:
    ftp://ftp.kernel.org/pub/linux/kernel/v2.4/
    If you want IPv6 how a module you MUST download modutils:
    ftp://ftp.kernel.org/pub/linux/kernel/modutils/

    Skip at kernel's recompiling:
    Log in as root and copy two downloaded files in /usr/src:
    [root@localhost tmp]# cp linux-2.4.<version>.tar.gz /usr/src
    [root@localhost tmp]# cp modutils-2.4.<version>.tar.gz /usr/src

    Note: <version> is number of version, of course :PPP
    Digit:
    [root@localhost src]# tar -zxvf linux.2.4.<version>.tar.gz

    Enter in generated directory:
    [root@localhost src]# cd linux.2.4.<version>
    [root@localhost linux-2.4.<version>]# make menuconfig

    Now select follow options:
    Code maturity level options -> <*> Prompt for development and/or incomplete code/drivers
    Networking options -> <*> Packet socket
    -> <*> Unix domain sockets
    -> <*> TCP/IP networking
    -> <M> The IPv6 protocol
    File systems -> <*> /proc filesystem support
    Kernel Hacking -> <*> Magic sysrq key

    Note: if you want IPv6 how built-in select <*> The IPv6 Protocol (not M).

    Exit and save:
    Do you wish to save your new kernel configuration? <Yes> <No>
    Yes, of course :P

    Now:
    [root@localhost linux-2.4.<version>]# make dep ; make bzImage ; make modules ; make modules_install
    This operation is very long (1h and 30' on my P-III 450 Mhz :///).
    After the wait move you in follow dir:
    [root@localhost linux-2.4.<versione>]# cd /usr/src/linux-2.4/arch/i386/boot
    [root@localhost boot]# cp bzImage /boot/vmlinuzipv6

    Now in:
    [root@localhost boot]# cd /usr/src/linux-2.4
    [root@localhost linux-2.4]# cp System.map /boot

    Now you must configure your bootloader for automatic load of new kernel:
    -[ LiLo:
    edit /etc/lilo.conf in follow way:
    image = /boot/vmlinuzipv6
    root = /dev/hd**
    label = LinuxIPv6 read-only

    Note: ** after hd represents HD and partition of /
    For know what is your / partition, from shell digit:
    [root@localhost etc]# df
    Filesystem 1k-blocks Used Available Use% Mounted on
    /dev/hdb2 8119776 1901788 585520 25% /
    /dev/hdb1 46636 6745 37483 16% /boot
    none 31104 0 31104 0% /dev/shm

    In this case you must write hdb2, save and digit from shell: lilo.

    -[ Grub:
    Edit /etc/grub.conf in follow way:
    kernel /vmlinuzipv6 ro root=/dev/hd** hdc=ide-scsi
    Save and exit.

    Now install modutils:
    Move you in /usr/src and digit:
    [root@localhost src]# tar -zxvf modutils-2.4.<version>.tar.gz

    Enter in generated dir and digit:
    [root@localhost modutils-2.4.<version>]# ./configure ; make ; make install

    Now you can reboot your system.
    System was crashed? Well digit:
    [root@localhost root]# /sbin/modprobe ipv6
    This comand start IPv6 module, you can add this in /etc/rc.d/rc.locale
    for automatic execution on boot.

    Well, check if module is active:
    [root@localhost root]# ifconfig
    lo Link encap:Local Loopback
    inet addr:127.0.0.1 Mask:255.0.0.0
    inet6 addr: ::1/128 Scope:Host
    UP LOOPBACK RUNNING MTU:16436 Metric:1
    RX packets:177 errors:0 dropped:0 overruns:0 frame:0
    TX packets:177 errors:0 dropped:0 overruns:0 carrier:0
    collisions:0 txqueuelen:0
    RX bytes:12330 (12.0 Kb) TX bytes:12330 (12.0 Kb)

    Most important line is inet6, if is not present you had mistook something.
    If you use an old release of linux I adivise of download follows packets:
    net-tools: http://www.gnumonks.org/ftp/pub/mirror/linux/iputils/
    iputils : ftp://ftp.netwinder.org/users/p/philib/

    -[ net-tools:
    [root@localhost tmp]# tar -zxvf iputils-ss000121.tar.gz
    Enter in created dir and digit make.

    -[ iputils:
    Copy in /usr/src and digit:
    [root@localhost src]# bunzip2 net-tools-1.60.tar.bz2
    [root@localhost src]# tar -zxvf net-tools-1.60
    Enter in created dir and digit:
    [root@localhost src]# make config ; make ; make -n install

    Check a lot of things, edit /etc/protocols and add follows lines:
    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 fo IPv6
    icmp6 58 IPv6-ICMP # ICMP for IPv6
    ipv6-nonxt 59 IPv6-NoNxt # No Next Header for IPv6
    ipv6-opts 60 IPv6-Opts # Destination Options for IPv6

    Edit /etc/hosts:
    ::1 localhost-v6.localdomain localhost-v6
    # Multicast IPv6
    fe00::0 ip6-localnet
    ff00::0 ip6-mcstprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters
    ff02::3 ip6-allhosts

    Now ping in v6 our localhost:
    [root@localhost etc]# ping6 ::1 -c 3
    PING ::1(::1) from ::1 : 56 data bytes
    Warning: time of day goes back, taking countermeasures.
    64 bytes from ::1: icmp_seq=0 hops=64 time=207 usec
    64 bytes from ::1: icmp_seq=1 hops=64 time=126 usec
    64 bytes from ::1: icmp_seq=2 hops=64 time=138 usec

    --- ::1 ping statistics ---
    3 packets transmitted, 3 packets received, 0% packet loss
    round-trip min/avg/mdev = 0.126/0.157/0.207/0.035 ms

    Now you must active a Tunnel Broker.
    Remember of update the Tb if you haven't a static IP address.
    After activation and update digit:
    [root@localhost root]# ifconfig
    lo Link encap:Local Loopback
    inet addr:127.0.0.1 Mask:255.0.0.0
    inet6 addr: ::1/128 Scope:Host
    UP LOOPBACK RUNNING MTU:16436 Metric:1
    RX packets:149 errors:0 dropped:0 overruns:0 frame:0
    TX packets:149 errors:0 dropped:0 overruns:0 carrier:0

    RX bytes:9670 (9.4 Kb) TX bytes:9670 (9.4 Kb)

    ppp0 Link encap:Point-to-Point Protocol

    RX packets:37 errors:2 dropped:0 overruns:0 frame:0

    RX bytes:23926 (23.3 Kb) TX bytes:2516 (2.4 Kb)

    sit0 Link encap:IPv6-in-IPv4
    inet6 addr: 3ffe:8172::d:3b50/124 Scope:Global

    collisions:0 txqueuelen:0
    RX bytes:312 (312.0 b) TX bytes:8296 (8.1 Kb)

    Now ping in v6 a server6:
    [root@localhost root]# ping6 irc6.edisontel.com
    PING irc6.edisontel.com(irc6.edisontel.com) 56 data bytes
    64 bytes from irc6.edisontel.com: icmp_seq=1 hops=62 time=179.835 msec
    64 bytes from irc6.edisontel.com: icmp_seq=2 hops=62 time=229.955 msec

    --- irc6.edisontel.com ping statistics ---
    3 packets transmitted, 2 packets received, 33% packet loss
    round-trip min/avg/max/mdev = 179.835/204.895/229.955/25.060 ms

    If you haven't a reply digit Crtl+C (for stop ping6)
    and disactive sit0 interface (is interface ov IPv6):
    [root@localhost root]# ifconfig sit0 down
    and re-update Tb.

    Now you must configure your IRC client for IPv6.
    Download most recent version and decompress and follow this istructions:

    -[ Xchat:
    ./configure --enable-ipv6 ; make ; make install

    -[ Kvirc:
    ./configure --with-ipv6-support ; make ; make install

    -[ BitchX:
    ./configure --enable-ipv6 ; gmake ; gmake install

    Join IRC and good chat !!!

    - [ APPENDIX ] -
    This is a little script to up sit0 interface:
    --- Cut here
    #!/bin/sh
    IPV6="your IPv6 address"
    IPV4="address of tunnel"
    ifconfig sit0 up
    ifconfig sit0 add inet6 $IPV6
    route -A inet6 add 2000::/0 gw ::$IPV4
    echo "Tb updated !!!"
    --- Cut here
    Save as act.sh.

    - [ GREETINGS ] -
    Thanks to #99posse channel and my friends.
    Special thanks to jesty, Morf3u5Ck, kiara (you are special) & vale.

    You should also obtain a link to the 6bone. I mean, to be able to use any of the 'cool' features IPv6 has to offer.........
    Mankind have a great aversion to intellectual labor; but even supposing knowledge to be easily attainable, more people would be content to be ignorant than would take even a little trouble to acquire it.

    Well this is a very little HowTo to help other newbies (I'm too), on IPv6 configuration.
    I'm studing this protocol and I know it a little bit.
