netns.sh stuck at ncat.

[René van Dorst]

Hi Jason,

Tested the latest code on my Solidrun Cubox with Marvell Dove 88AP510 SoC.
But is get stuck on ncat. Device did not crash. I can terminate the  
script with ctrl-c.

Probably a weird config ;-)

Crosscompiled kernel 4.13.14 and wireguard on F26 from git source.
