Seems like this depends on inetd to provide tcp/udp echo services.
Thats fine, I don't have any objections.
The ICMP test passes when I remove tcp/udp test.
Could you please either remove the unused functions or provide some
comment in the commit message why these helpers are there, but currently
unused? (I see you commented out the calls).
[ the modprobe error is because I don't have cttimeout but it does appear to have no immediate
ill effect ]
Thanks!
