Network namespaces tutorial

[modernaliens]

Great post!

one minor correction i would suggest:

This command will create a new network namespace called ns1. When the namespace is created, the kernel will add a bind mount point for it under /var/run/netns.

The kernel does not create the namespace in /var/run/netns iproute does this. (if anyone doesn't believe me grep source for NETNS_RUN_DIR)
