Merged as it's some improvement. I'm not sure if I invest time to FTP in the
future, maybe we should really delete it.

The only significant change I did was to force running over SSH:
with RHOST="${RHOST:-localhost}"

In my case only first half of the tests is working (suppose just wrong setup),
but on netns everything si broken and you also tested it on SSH I dared to do
this change. I documented the proper fix above in case anybody cares.

Kind regards,
Petr
