# ifupdown-netns

Some simple scripts to simplify configuring network namespaces on Debian-like
systems.  Copy them into the corresponding directories under `/etc/network`.

To configure an interface in a namespace:

```
auto eth1
iface eth1 inet manual
  netns myns
```

On invocation of `ifup`:
  * if the namespace doesn't exist it will be created
  * if the folders `if-down.d`, `if-post-down.d`, `if-pre-up.d` and `if-up.d`
    under `/etc/netns/<namespace>/network` don't exist, they will be created
  * if the `/etc/netns/<namespace>/network/interfaces` file doesn't exist a
    blank one will be created
  * if it does and the interface is configured the the script will invoke `ifup`
    for this interface inside the namespace.
