host ,client -server and where to read it.Thanks.

   Yes, you run the command above on your laptop. Btw, if you want to access
port 2947 on the laptop from some other host, you will need to cut off the
first localhost: so the command reads

$ ssh -L 2947:localhost:2947 debian-gta02 -- sleep inf &

and maybe also change some ssh settings. See the ssh manual page.

Hi,

Can I use this to forward the 2947 port from Neo to 2947 on laptop ,in other
sense can I get the values being generated from Neo at 2947 of Neo be
available at 2947 on the laptop.

Please advice.

   It is the same because that is the whole point of having fso-gpsd. Like
it says on the first line: "If backward compatibility is needed, use ogpsd
with fso-gpsd."

> And in my FR I could not find the folder /tmp/nmeaNP.

   OK, the wiki page is a bit ambiguous in that section, but where it says
"Neo" it refers to your Neo Freerunner or Neo 1973 and where it says "host"
it refers to the "other" device you have, such as your laptop or desktop
system.

   Please do not refer him to outdated information. The page even has a
warning at the top of it:

WARNING: Most of this article is only relevant for Om 2008. The gpsd
has been obsoleted by the ogpsd which offers a DBUS interface. Do
not run these two daemons side by side. If backward compatibility is
needed, use ogpsd with fso-gpsd.

   Instead of messing with the serial port, connect to the Neo over TCP/IP
on the standard gpsd port (2947). You will probably have to change how
fso-gpsd is started, so the option '-S localhost:gpsd' reads just '-S gpsd'.

   Alternatively, and this is what I suggest, use ssh to forward connections
from the gpsd port on your laptop to the gpsd port on your Neo:

$ ssh -L localhost:2947:localhost:2947 debian-gta02 -- sleep inf &

Well there is only information about reading NMEA using the older gpsd but
not the fso-gpsd.And in my FR I could not find the folder /tmp/nmeaNP.

If you really want to forward serial port, you can use socat for that.

Are you sure you want to do that? gpsd is designed in a way to be
possible to get gps data over the network. And fso-gpsd can do that
too.

Just connect FR and laptop in some way (USB/BT/Wifi) and you're done.

If you really want to forward serial port, you can use socat for that.

[RANJAN]

Hi,

Is it possible to setup a serial connection between the FR and the laptop
using a virtual comm port or USB to serial converter and then read the GPS
NMEA sentences?Please advice me.

Thanks and Regards
