If you have a recent enough iproute2 package you can use: ip netns add ns1 ip netns exec ns1 bash # get the PID in the session and don't close it iw phy phyX set netns $pid_of_that_shell # you can close the bash now; phyX will remain in ns1 Or you could try using ipv6 link-local addresses which will not require you to use namespaces at all.
