Golang implementations of Linux Namespaces

nspipe is a simple example application included with go-namespaces. It lets you bind a socket into a namespace and connect the other end to some other tcp address.

Outside the namespace in a namespace with routable internet networking:

nspipe -t $TARGET_PID

Inside the namespace with private networking:

telnet 127.0.0.1 23

You can also create a new namespace using iproute2

sudo ip netns add test
sudo ip netns exec test netstat -ltup

nspipe -p /var/run/netns/test
sudo ip netns  exec test netstat -ltup
