Permanent WSL DNS Fix (WSL 2.2.1+)

If you're encountering ping github.com failing inside WSL with a Temporary failure in name resolution, you're not alone — this has been a long-standing issue, especially when using VPNs or corporate networks.

This issue is now fixed robustly with DNS tunneling, which preserves dynamic DNS behavior and avoids limitations like WSL’s former hard cap of 3 DNS servers in /etc/resolv.conf.

DNS tunneling is enabled by default in WSL version 2.2.1 and later, meaning that if you're still seeing DNS resolution issues, the first and most effective fix is simply to upgrade WSL. Upgrading WSL updates the WSL platform itself, but does not affect your installed Linux distributions, apps, or files.

To upgrade WSL, follow these steps,

To limit a CPU to a certain C-state, you can pass the processor.max_cstate=X option in the kernel line of /boot/grub/grub.conf.

Here we limit the system to only C-State 1:

    kernel /vmlinuz-2.6.18-371.1.2.el5 ... processor.max_cstate=1

On some systems, the kernel can override the BIOS setting, and the parameter intel_idle.max_cstate=0 may be required to ensure sleep states are not entered:

There are three ways to get puppet modules into Katello. The third way supports git.

1. By creating a repo with its URL set to a puppet forge. This can be http://forge.puppetlabs.com for example. There must be an API there (e.g. http://forge.puppetlabs.com/modules.json?q=rvm). You can also use a tool like https://github.com/drrb/puppet-library to setup your own forge.
2. By uploading modules. You can even create a repo with no URL and just upload your puppet modules via the URL. To upload modules, go to the repo details screen and see the module upload section.
3. By using the pulp puppet module builder tool. See their documentation for more information. The script comes with Katello. For the repo URL, simply enter the filesystem path (e.g. "file://opt/puppet/modules").
