Here is the steps from the above links:
Code: Select all
Step 1) Strictly follow one of the above links, to the letter. Dasien's post
*(on bottom)
is a summary of the Wiki page but, it includes code one could easily copy and paste into the terminal to accomplish the goals of said Wiki page.
Step 2) Edit /etc/netconfig on two lines. Find these lines:
Code: Select all
udp6 tpi_clts v inet6 udp - -
tcp6 tpi_cots_ord v inet6 tcp - -
Comment them with a '#' sign:
Code: Select all
#udp6 tpi_clts v inet6 udp - -
#tcp6 tpi_cots_ord v inet6 tcp - -
Gratuitous advice: Before editing sytem files, "always" make a backup copy by appending .backup to the end of a filename.
That should clean up any remaining IPv6 processes.
Code: Select all
However, since following directions seems to be something of a lost art, the commands below can be copied-and-pasted to achieve exactly the same effect.
Step 1: Open a terminal and su to root
Step 2: Verify that IPv6 is (or is not) active
Code: Select all
netstat -tunlp |grep p6 |wc -l
If the result is anything other than 0, then one or more IPv6-aware processes is running.
Step 3: Follow Wiki directions (aka copy-and-paste these three lines into a root terminal).
Code: Select all
echo net.ipv6.conf.all.disable_ipv6=1 > /etc/sysctl.d/disableipv6.conf
sed '/::/s/^/#/' /etc/hosts >/etc/dipv6-tmp;cp -a /etc/hosts /etc/hosts-backup && mv /etc/dipv6-tmp /etc/hosts
sed '/ipv6=yes/s/yes/no/' /etc/avahi/avahi-daemon.conf >/etc/avahi/dipv6-tmp;cp -a /etc/avahi/avahi-daemon.conf /etc/avahi/avahi-daemon.conf-backup && mv /etc/avahi/dipv6-tmp /etc/avahi/avahi-daemon.conf
Step 4: Reboot
Step 5: Repeat Steps 1-2
Code: Select all
#netstat -tunlp |grep p6 |wc -l
should now return 0
Again, these steps will disable IPv6 on a stock install of Squeeze. If you have additional IPv6-aware processes running (server daemons in particular), then additional steps may be required, as outlined in the two articles linked to below.

What are the benefits of disabling IPv6? Is it safe?
If a person did in fact follow these steps and disable IPv6, will there be consequences in the future when IPv6 is the standard?
Thanks for your response, if any.
