If you spend some time of troubleshooting network namespaces (ns) you will note that sometimes you don't even know if you are inside one, or two, :-P of them.
- Wouldn't be good if you don't have to paste neutron long network ids to make ns names?
- Wouldn't be great if your prompt told you in what ns are you?
- Wouldn't be awesome if you can get into router's namespaces too?
I've created an script called netns which accepts one parameter, the name of of the network or router you want to get into it's namespace.
Also is necessary to modify ~/.bashrc for the user running the command (root most likely).
# netns network-name
# netns router-name
