I am running Ubuntu 6.10, and have plptools installed. This is a
collection of programs for connecting to a Psion hand-held computer. I
have used it before under Fedora.
In order to connect to the Psion, which is connected to /dev/ttyS0, a
daemon called 'ncpd' is run. This seems to be working
fine: /var/log/daemon reports:
daemon started. Listening at 127.0.0.1:7501 using device /dev/ttyS0
Connected with a S5 at 115200baud
(S5 is the variety of Psion computer that I have.)
In order to read the files on the Psion, I then have to run another
daemon called 'plpnfsd'. Although it prints an encouraging message on
the screen, it actually exits immediately. The log file reports:
connected, status is 0
bind to reserved port: Permission denied
I have tried running ncpd and plpnfsd using an arbitrary different port,
but with exactly the same results.
My firewall settings seem to be fine, so far as I can tell.
Can anyone shed any light on why the port is reported as "reserved"?
