If you’re encountering odd networking errors with Linux servers and desktops, try disabling IPv6 to aid you in your troubleshooting or to provide a temporary fix. If you disable it, some Windows components may not work properly. This isn’t a perfect solution, but sometimes you have to be creative in your troubleshooting. Inet_interfaces = 127.0.0.1 An imperfect solution Name: DisabledComponents Type: REGDWORD Min Value: 0x00 Max Value: 0xFF (IPv6 disabled) Moving right along Now that we’ve gotten that out of the way, let’s take a look at how Windows uses IPv6 even when your DHCP server is providing it an IPv4 address and your Internet router doesn’t support it. Open the /etc/postfix/main.cf file, comment out the localhost line, and add the IPv4 loopback like so: To fix this, you’ll have to use an IPv4 loopback. If you use Postfix, you could encounter issues with the service starting. To fix that issue, you must open the /etc/ssh/sshd_config file and change the #AddressFamily any to AddressFamily inet. If you happen to use X Forwarding through ssh, disabling IPv6 can break this system. To re-enable IPv6, remove the above lines from /etc/nf and reboot the machine. Add the following at the bottom of the file:

Here’s how to disable the protocol on a Debian-based machine.Ģ. To re-enable IPv6, issue the following commands:

Issue the command sysctl -w .disable_ipv6=1.

Here’s how to disable the protocol on a Red Hat-based system: I’ll show you how to disable IPv6 on Red Hat- and Debian-based distributions.

You guessed it, we’re going to be working with the command line. Also, you should consider this a temporary fix.) Command line ( Note: I recommend disabling IPv6 only when you’ve exhausted all other options. I’ll show you how to disable IPv6 on a Linux machine.

After a while I would re-enable IPv6 to see if a router firmware update (and a desktop OS update) had solved the problem in some instances, it solved the issue and IPv6 could remain enabled, though in other instances, IPv6 would have to be disabled again. I’ve had a few instances where communication between a Linux desktop and an ATT UVERSE router would constantly drop, and disabling IPv6 was the only solution that worked.

If you have hardware that perfectly implements IPv6 and software that uses it correctly, this is a non-issue. Since some hardware doesn’t take advantage of IPv6 (and most admins are still working with IPv4), a temporary and easy solution is to disable IPv6 the protocol can be re-enabled when the time comes when the issue has been permanently resolved. However, I have seen rare instances in which IPv6 has caused network problems. IPv6 offers a much larger addressing scheme than IPv4, which is one of the many reasons why it was developed.
