ipv6 and XDMCP

Discussion in 'Linux Networking' started by Captain Dondo, Jan 19, 2005.

  1. I'm setting up a network where logins happen via gdm + XDMCP. Everything
    works fine, except that all the Fedora Core 2 machines show up twice in
    the browser, once with their IPV4 name and IP address, and once with just
    the IPV6 address.

    This is really frustrating... I can't figure out how to turn off the
    ipv6 address in Fedora Core 2.

    Is there a way to prevent ifconfig (or the kernel) issuing out IPV6
    addresses? Do I need to turn off all of the IPV6 stuff in the kernel and

    Is there a setting somewhere that I've missed?

    I know on Mandrakelinux you can read
    to see what can controls can be used.

    For us,

    /etc/sysconfig/network and add the line
    NETWORKING_IPV6=no (note: add a carriage return)

    /etc/modules.conf and add the line
    alias net-pf-10 off (note: add a carriage return)

    if you do not have
    /etc/modprobe.conf and add the line
    alias net-pf-10 off (note: add a carriage return)

    You might try:

    In /etc/syscong/network

    and in /etc/modprobe.conf
    # Turn off IPv6
    alias net-pf-10 off
    alias ipv6 off

    From /etc/sysconfig/networking-scripts/ipv6-init.global:

    # NETWORKING_IPV6=yes|no: controls global IPv6 initialization (default: no)

    Note the default.... Nowhere was I able to find a line that says

    Clearly, the default has changed from Fedroa Core 1 to 2 and the docs have
    not kept pace...


    (I know, I should offer to update the documentation.....)

    Thanks for the pointers, guys. I'll make the changes when the computers
    wake up this morning....
