Thank you to all respondants re the above, especially Troy from IBM who
has raised a defect, responded very quickly and has offered a temporary
patch, definatly an excellent responce. The problem seems to be
with the declaration of the port being short rather than unsigned short.
Negative values for -P do not work as a few people suggested.

Security bugs with AIX should be addressed to

This, in the experience of myself and others who replied is much faster
method of getting security related problems fixed.

Thanks again,
