Viewed 69 times

Summary

An administrator may wish to disable IPv6 on all VRAs.

Steps

To disable IPv6 on all VRAs utilizing the Multi-Session Tool, follow the below steps:

  1. Download the Multi-Session Tool from this link.

  2. Connect the Multi-Session Tool and get the list of VRA IPs.

  3. Run the following command to the Multi-Session Tool's command box to check current status: 

    1. cat /proc/sys/net/ipv6/conf/all/disable_ipv6

    2. Note: This should output 0 as it is not disabled by default on the VRAs.

  4. Run the following command to the Multi-Session Tool's command box to disable IPv6:

    1. sysctl -w net.ipv6.conf.all.disable_ipv6=1

  5. If you hover your cursor over the green V next to the VRAs IPs, you should see the following output per VRA:

    1. net.ipv6.conf.all.disable_ipv6 = 1

  6. To verify, run the following cat command to list the value of the "disable_ipv6" attribute:

    1. cat /proc/sys/net/ipv6/conf/all/disable_ipv6

  7. You can run the other commands regarding IPv6, just prefix them with "sysctl -w" which have been arranged below:

    1. sysctl -w net.ipv6.conf.default.disable_ipv6 = 1

    2. sysctl -w net.ipv6.conf.lo.disable_ipv6 = 1

  8. Once all changes are complete across all VRAs, run the following command to persist the changes by restarting the networking daemon: 

    1. /etc/init.d/networking reload
