IP Address not displayed

[James Young]

Ok I have had my PI 3000 for a couple of years and thought that the System IP address was just a place holder until I saw a video where someone demonstrated it actually works (SMH) all this time I have located the IP through DNS on my router initially...SO what is the secret to get my IP Address displayed on the Pi 3000.

TIA

[RandyR]

Not sure how your are wired up, but if PicoChess is running and the Pi is connected to the network, you should be able to use the buttons to access the System/information menu to see the ip address.

Randy

[James Young]

I tried wired and wireless and for as long as I had this box the system's IP address has never displayed no matter what version of code I run on the PI 3000. I just looking to see if there is an off-on switch in the code.

[Randy Reade]

How is your clock attached?

I am assuming when playing with the DGT board...Bluetooth

[Randy Reade]

I guess I'm just not understanding. I assume you don't have a DGTPi. Are you just running PicoChess on a Pi (which model?) connected to the DGT board via Bluetooth? And how is your DGT3000 clock connected? Are you using the clock cable to connect it to the board?

DGT PI 3000 which is the clock/chess computer All in one

[Randy Reade]

Hmmm, that's strange. I'll check my DGTPi and see if it shows my ip address.

[James Young]

Even with a static address given NADA nothing shows up

[RandyR]

So I tested it using the latest v3 image and the ip address is displayed. But with the version that shipped with the DGTPi (v0.9l) it gives the 'no ip addr' text. The issue is with an outdated url which determines your geo-location, in the utilities.py file. If you want to fix it, use the nano editor via ssh:

cd /opt/picochess

sudo service picochess stop

sudo nano utilities.py

Use the arrow keys to scroll down to the 'def get_location():' code, somewhere after line 250 depending on your PicoChess version (Alt-C will display the line number location of the cursor at the bottom of the nano window).

Then change the url in the 'response =' line to this:

        response = urllib.request.urlopen('http://will6.de/freegeoip')

Don't change the indentation (8 spaces here) as Python is very particular bout this!  :^)

And notice the http not https.

Save your edits:

Ctrl-O

And restart PicoChess:

sudo service picochess start

[James Young]

Already there now I am really confused

def get_location():

    try:
        sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

        sock.close()

        response = urllib.request.urlopen('http://will6.de/freegeoip')

        j = json.loads(response.read().decode())
        country_name = j['country_name'] + ' ' if 'country_name' in j else ''
        country_code = j['country_code'] + ' ' if 'country_code' in j else ''

        return (city + country_name + country_code).strip(), ext_ip, int_ip
    except:
        return '?', None, None

[RandyR]

If you put http://will6.de/freegeoip into a browser, does it show your location? Or just click on that link.

[James Young]

it does indeed and gives my External address as the ip

[Randy Reade]

Ok. So it's not hanging there.

Let's see if we can run the code that gets the internal IP address. We'll enter some commands into the python interpreter:

Using ssh again, launch python3:

python3

Then enter the following 5 individual commands at the >>> prompt:

import socket

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.connect(('8.8.8.8', 80))
int_ip = sock.getsockname()[0]

print(int_ip)

Does it display the ip address of your DGTPi?

Ctrl-D gets you out of the interpreter.

[James Young]

I am on it, give me 10 minutes 

[James Young]

yes it comes back with my internal address

[RandyR]

What exactly do you see on the clock when you select the System/Information/IP adr menu?

[James Young]

NO IP ADDRESS

[RandyR]

Well, I'm out of ideas. Perhaps a bad image? Are you using one of mine? I would suggest the Lite image for the DGTPi.

[James Young]

I am indeed running the lite version and I have the desktop as well and the results are the same NO IP ADDRESS everything else appears to be fine. Thanks for trying Randy.. While I have you is there a list of all the Switches/options for the picochess.in examples tutor-comments = all? are there other variables not listed in the documentation?  I have seen in one file pi@picochess:  not sure what it is used for....I am just interested in all the available options ( the undocumented enhancement as we say in the IT world.

[James Young]

Also Shiv was working on bringing his server back online that populates the Book information for the Pico Web server, is there a setting I need to make to access the information or is it written in the code
?

[RandyR]

I think they are all documented in the picochess.ini file itself.

The book info will populate once Shiv fixes it. If there are any code changes, he'll let us know.

[James Young]

cool thanks again for your help!!! iF i find a solution for the System Ip i will let you know.

[RandyR]

Yes, it will be interesting to see what fixes it. Maybe someone else has an idea.

Good luck.

Randy

[Marc Hamilton]

I'm getting the IP address displayed... Mark

[Marc Hamilton]

Same here... I get "No Ip Addr" when selecting the menu option

[Scally]

Hi,

Mine on V3 is working as designed, note no board is attached …

https://www.dropbox.com/s/meknmlmiqgm4xu6/2022-06-13%2011.03.53.mov?dl=0

Al.

[James Young]

Board attached, not attached even with a statically configured address, the response is the same NO IP ADDRESS; I am curious, though, what is the difference between the standard Pi 3000 and yours, the limited edition?

[Scally]

There is no difference, I just bought the DGT3000 Limited Edition and swapped the tops to match my Revelation II. My base is customised too with built in speaker etc kindly provided by Wilhelm. There are many posts on here showing the build etc …

As to why you don’t see the IP address, I’m stumped too. Not that it should make any difference but have you tried an Ethernet cable directly from your router to your DGT Pi?

Al.

[James Young]

Correct wired and wireless 

[RandyR]

Jim/Marc,

Do you have the default entry 'location = auto' in your picochess.ini file and is your location shown in the web server interface?

[Mark HL]

I can answer that without looking.

No, I do not have it set to auto because I didn't want the PGN data to disclose my location. I have a manual entry of 'Washington USA' 

I'll set it to auto and see if it shows my IP.

Your initial post said 'Washington USA' not 'Washington, USA'. Did you have a comma in there?

[RandyR]

Hmmm, I tested Washington, USA and it works for me. Maybe a reboot is needed...

[RandyR]

Nope. Reboot made no difference. I still get the ip address. Is it possible you have the 'location =' entry in 2 places?

[m371...@gmail.com]

Okay this is a bit strange… I was not seeing my IP address until I changed the location entry to ‘auto’. However, I replaced the Micro SD card with another one with the exact same flash

and it IS showing my IP address with the location data entered as Washington, USA.

There might be something wrong with the picochess.ini file. Perhaps copy over a clean, un-edited version of picochess.ini to that 'bad' sd card, then make the location change.

I just set the location back to ‘Washington, USA’ on the card that would previously not show the IP and it now shows it.

[RandyR]

Did you by chance edit the picochess.ini file on Windows initially? I always use nano directly on the Pi.

[RandyR]

Jim, I think you cross-posted so I'll reply here.

You edit the same way I do so that shouldn't be the issue (although I usually use a Linux laptop to ssh in), but I still suspect some corruption in your picochess.ini file. When you get a chance, can you either burn a new Lite image, make no changes and connect using an ethernet cable, then test; or copy over a clean picochess.ini file from the image (perhaps using scp) then test? I'll attach the file just in case.

no change...is this a firmware issue? I mean I have not seen this box ever display and address

[RandyR]

Sorry, life called.

No. Updated firmware is stored on the SD card unless you have a Pi4. Let's see if the python code is failing. Run the 2 attached python files on the Pi, in the home folder. E.g.:

python3 test.py

Here is the code:

test.py:

import socket
import json
import urllib.request

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.connect(('8.8.8.8', 80))
int_ip = sock.getsockname()[0]
sock.close()
response = urllib.request.urlopen('http://will6.de/freegeoip')
j = json.loads(response.read().decode())
country_name = j['country_name'] + ' ' if 'country_name' in j else ''
country_code = j['country_code'] + ' ' if 'country_code' in j else ''
ext_ip = j['ip'] if 'ip' in j else None
city = j['city'] + ', ' if 'city' in j else ''

print((city + country_name + country_code).strip(), ext_ip, int_ip)
 

test2.py:

import socket
import json
import urllib.request

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.connect(('8.8.8.8', 80))
int_ip = sock.getsockname()[0]
sock.close()
response = urllib.request.urlopen('http://will6.de/freegeoip')
j = json.loads(response.read().decode())
country_name = j['country_name'] + ' ' if 'country_name' in j else ''
country_code = j['country_code'] + ' ' if 'country_code' in j else ''

ext_ip = j['IPv4'] if 'IPv4' in j else None

city = j['city'] + ', ' if 'city' in j else ''

print((city + country_name + country_code).strip(), ext_ip, int_ip)

What do you see?

[RandyR]

You can use the interpreter as well.

Ok. Something is not right. I just used scp to transfer the files to the DGTPi and they both ran fine. Now, I'm using a Linux laptop so I know there isn't any change to the file by Windows before it is sent. I'm wondering if Windows is saving them in dos format when they need to be unicode (UTF-8). The command I used was:

scp test* pi@<ip address>:~/             <---- enter the ip address of your DGTPi

Then on the Pi:

cd ~

python3 test.py

python3 test2.py

Maybe I should try from Windows to see if that's the issue you are having.

Also, you didn't answer this:

When you go here:

http://will6.de/freegeoip

do you see the word 'city' in the string? If so, is there a city name after the : ?

I just tested using Powershell in Windows 11 and no errors.

Are you by chance using a NAT router?

[James Young]

"country_code":"US","country_name":"United States","city":null,"postal":null,"latitude":37.751,"longitude":-97.822,"IPv4":"75.46.236.166","state":null}

of course, everything is NAT from the private to the public address however in one case I do have a double NAT... I run servers behind a router that is behind my ISP's router. whether connected directly to the ISP router or not I still don't get the IP address displayed.

I have been using WinSCP to upload the files

[James Young]

what is the test* used for? I get the login cred's after login I get   test* no such file or directory

I guess that's why it is failing. There's no null handling for the city name. Even when you enter a location in picochess.ini, the code in utilities.py still runs. It fails and you don't receive the internal ip address. It may require a different geo-locator site, or some different code to handle null returns.

test* will transfer all files beginning with test in the current folder, where scp is being run. Only useful if it only contains test.py and test2.py.

[James Young]

Well now we have the clue , it is curious that I would need special modifications ...I wonder how many others are not able to get the IP to display? Well, I am calling it night my friend, thank you VERY much for trying all day to help resolve this issue. Chat with later

[Randy Reade]

Ok, Jim.

I'll try to find some code that will handle 'null' from JSON.

Goodnight.

Randy

So, from what I've been reading, json.loads should handle the null value. I'll have to test the code to see if it's working properly using fake data that has null in it.

Something for tomorrow.

Hi,

My location setting in my picochess.ini file:

# location = auto
location = Bermondsey, London

Al.

[James Young]

Hey Al

The location setting appears to not work at least not on my network but works when I am in Tampa. the ISP in Tampa is Spectrum, here at home it's AT&T. I can set it manually as you suggest but it does not resolve the "no IP address" which Randy is graciously working to resolve for perhaps many who are experiencing this issue.

[Scally]

I have to set my location manually as the automatic setting is miles from my real location.

Yours is the first problem of this type that I’ve heard of, silly question but have you got a VPN set that suppresses your IP address?

If not, I’m sure Randy will get to the bottom of your problem …

Best of luck …

Al.

[RandyR]

I think I have a solution.

The issue is in the code that determines the location. If the geo-location site is unable to determine a property (e.g., city, country or country code) it returns a null value. The Python 'json.loads' command correctly changes the null value (not allowed in Python) to None. But our PicoChess code creates some strings using the city name, country name and country code, concatenating them with spaces and commas. Well, if you try to concatenate with a 'None' value it will throw an exception. Our code's exception handler for this function will return a '?' for the location, and 'None' for the internal (network) and external ip addresses. This would be fine if the Pi is not connected to the internet (and Dirk's location variable in the picochess.ini file allows you to enter your own location to handle this instance, as well as poor geo-location, which Al mentioned above). But in the case where you ARE connected to the internet, any null value would prevent the ip address from showing via the System/Information/ip address menu.

Although there are probably better ways to code this (I'm definitely a newbie in Python) I have altered the get_location() function in utilities.py so it should show the internal ip address even if it can't determine your location name. Below is the new code which begins around line 263 in utilities.py (and I have attached the updated file to this post). Note that indentation is critical in Python (multiples of 4 spaces).

Jim, if you can test this on your system and let me know if it works, I can add it to my images. Please test with 'location = auto' and 'location = <whatever you want>' in the picochess.ini file. Also, check the display in the web server.

I would also be grateful if someone else could do the same tests to make sure it doesn't break your current system. I tested on my DGTPi with the Lite image installed and it works fine.

You can make a backup of utilities.py by entering the commands (via ssh):

cd /opt/picochess

sudo cp utilities.py utilities.py.bak

To copy the file from a PC to the Pi with a shell opened in the folder containing the new file. NOTE: this will overwrite a file of the same name in the pi home folder without warning:

scp utilities.py pi@<ip address>:~/

Then, ssh into the Pi and execute the following commands:

sudo service picochess stop

sudo cp /home/pi/utilities.py /opt/picochess

sudo chown root:root /opt/picochess/utilities.py

sudo chmod 755 /opt/picochess/utilities.py

sudo service picochess start

Of course, if someone has a better solution, please advise.

Randy

Notes

Works wired and wireless and behind a double NAT network.

Auto location can not ID my city but does ID the United States as a part of the location
Manual Location no issues there

NO MORE "no IP address"

Yeah, code change to utilities.py (still) works for me too.

Thanks, guys. I'll update my images.
