this was my patch (idea was steve's). i've already sent a fix to
andrew. andrew please let me know if you haven't received it.
Ah, good. Please resend?
Actually, Chuck's patch and Steve's aren't quite the same. Both patches
fix the problem that the portmap daemon requires a request to set something
to come from a reserved port. In addition to this, Steve's patch reduces
the number of reserved ports that the kernel requires. This is the problem
that resulted in pmap_create() being incorrectly modified in the first
place.
Steve's patch correctly puts the support in rpc_getport() where it belongs.
Thanx...
