You have to replace “please-replace.invalid” by the IP address of the computer running the input driver. When the driver receives events from the app, it prints some dots.
OK. I’m getting close, I can feel it. I got into GIMP, found Network Tablet under Input Devices, set it too screen, put my computers IP Address into the tablet app and now nothing is happening. It looks like everything is setup the way that it should be, but I’m not getting any movement on the computer from the tablet.
Are there any dotts written in the terminal window, where you’ve started the networktablet driver?
It should look like this:
sudo ./networktablet
…
@rfc2822
As an improvement you should perhaps print the IP address of the computer if the networktablet driver is started.
No dots. It asks me for my password and then nothing. But when I close the the terminal a dialogue pops up saying “There is still a process running in this terminal” When I go to GIMP, it does have the Network Tablet listed, but it still isn’t working.

When there are no dots, the driver doesn’t receive anything. Either the IP address in the app is wrong (did you enter the IP address of the computer running the driver?), or the Android device is not connected to the same network (WLAN?), or a firewall blocks the traffic. (For instance, Fedora runs a restrictive firewall by default.)
The IP address is that of the computer running the driver, Ubuntu 12.04 doesn’t have any firewalls that would block this (that I know of), and they are both connected to the same wireless network (the household wifi).
I am supposed to be starting the driver BEFORE starting the app, correct?Sorry this is taking so much time and effort.

It makes no difference for the latest version (1.1). There’s another think that I suspect: the new version required some changes so it’s not compatible with the old driver anymore. And I have changed the port so maybe it would help to compile a new version of the driver (just delete it and fetch/compile again) and a new version of the app (deinstall / install again). This should help.
HA HA!!! Success! Thank you very much for sticking with me through this.
I have just started using the app, but so far it is very impressive. No bugs that I can see so far.
I will echo what a couple of other people have said and say that if there is anyway to get the screen to share in both directions (so that you can see on the tablet what is happening on the computer) that would be fantastic. But for now, I am really enjoying the app. Keep up the good work and thanks again.
Great to hear! Hope you enjoy it in the future and thanks for the comment on the Play store (yes, it was the dev himself that mailed with you) 
Closing this now!
here’s what i’ve done and still can’t get this to work. (toshiba satellite ultrabook, ubuntu 13.04)
downloaded networktabletx86 file to desktop
ss@ss-Satellite-U845t:~$ cd ~/Desktop
ss@ss-Satellite-U845t:~$ chmod a+x networktablet
ss@ss-Satellite-U845t:~$ sudo ./networktablet
the result said it is running on 0.0.0.0:40118 (altho i don’t recall verbatim)
app is installed on galaxy note 2
i have tried both the ip address of the computer on the local network, and the one spit out in the terminal 0.0.0.0
i see network tablet in input devices gimp 2.8 but it wont allow me to “save”
on the desktop i see no mouse cursor movement, nor do i see dots in terminal when i touch the tablet screen.
i have also downloaded gfxtablet-master folder with driveruinput folder+ in it but can’t figure out what to do with it if anything.
i’ve also added the repository in the terminal "sudo add-apt-repository http://github.com/rfc2822/GfxTablet
"
can’t wait to try some painting with my phone and gimp. i’ll happily donate to this project.
hello!
probably you need to set the firewall to allow port 40118.
in GIMP you don’t need to save, just set the mode to screen and exit the dialog!
if you need more help just ask again
cheers!

Hey Bernhard thanks for your quick reply! I have a firewall program but it
is not on.
Its funny, I just tried everything that I tried before I went to bed but
now it just suddenly started working! I had the firewall off but when I
turned it on but with opening port 40118 it just started working 
The good news is everything was as it should be. I was thinking that maybe
the drivers were not installed correctly.
Going to make a small but sincere donation now because this is a cool
app/feature, and especially since it supports Linux!
Cheers!
