Disabling IPV6

For no significant reason I decided to disable ipv6 on all local Slackware systems. Well, perhaps one reason. There is no need for ipv6 on the home LAN.

The process went quickly with only a few files to edit.

/etc/modprobe.d/aliases.conf

    alias net-pf-10 off  # INET6, IPv6 Protocol
    alias ipv6 off

/etc/modprobe.d/blacklist.conf

    blacklist ipv6

/etc/netconfig

Comment out the following two lines:

    #udp6       tpi_clts      v     inet6    udp     -       -
    #tcp6       tpi_cots_ord  v     inet6    tcp     -       -

Possibly some of the edits were not needed but I did not test.
