the only explanation that comes to mind is if i have

set_forward_no_connect(), but i have not found such a call. is there a
function call to revert set_forward_no_connect()?
it turned out that i had called set_forward_no_connect(). so only the
first problem remains, i.e., setting $fs without proto does not take
proto from $du, which is what wiki claims.
