Installation

Package names:

• Debian: bind9
• Fedora, Arch: bind

Setup

• Start named (using systemctl or whatever)

rndc-confgen -a

```

SPECIAL WARNING: Make sure your bind config is set up to allow underscores in hostnames, or else the check-name validation can cause bind to ignore entire zone files.

Fixing errors

"/etc/rndc.key: permission denied"

Error

$ ./manage.py maintain_migrate -b
[snip]
rndc: error: open: /etc/rndc.key: permission denied
rndc: could not load rndc configuration
Failed to reload rndc. Do you have permission?

Explanation

This error is raised because you don't have read access to /etc/rndc.key.

Workaround #1 (annoying but safe)

sudo when using the -b flag.

Workaround #2 (probably unsafe)

• Determine /etc/rndc.key's group:

$ ls -l /etc/rndc.key -rw-r----- 1 root named 77 Jun 13 23:01 /etc/rndc.key ```

On my system it's `named`.

• Give rndc the same group:

chgrp named which rndc

```

• Make rndc setgid

chmod g+s which rndc

```
