working fine on openbsd (and many more ...and not only linux based things).
I used it ago to perform tests openbsd <-> LCOS <-> Windows <-> ??? (=all of them
no linux ;)

You see this message on the openbsd host? I rather think you see it on
the other box from which you want to connect to the openbsd host.
So just as a shot in the dark: pf on openbsd host blocks port 5201. So
please check your /etc/pf.conf (see pf.conf(5))

It is unbound??? Didn't you say that iperf binds to port 5201 before???

I am sure that this is something we can fix easily :-)
But please provide more info to help you out.

There are more than one network tool. What exactly do you want to test?
Maybe you just want to see open ports?
From your other mails on this list I could imagine that maybe you just
want print the route packets take to a network host.
For this as an example you can just use traceroute(8) in base.
