You could check $NET0/TPHOSTS.LIST - the refused message tells me that
the TPMON thought that 131.142.12.34 is not allowed.  I am a little
suprised that that produces an errno=1, but who knows?  The reset by
peer might also be that it opened and ecided against allowing.  Note
that tPMON used to be open to the world - a true Trojan Horse that I
once used to copy a file from India.  But we closed it by giving you
control of who is allowed.
