pi not responding #3

Closed pav1996 closed 5 years ago

pav1996 commented 5 years ago

i have tried this app but it seems that i am doing smth wrong here....i succesfully download and install the package....i edited the library as described using different port number and password then i start the server but when i try to connect through the app it fails and the message says pi not responding...also i dont understand the part with the available parameters, am i supposed to write new lines in the library with them or modify some of the excisting ones?

arek125 commented 5 years ago

First check if server is properly running with: sudo systemctl status rgc.service. Show me the output.

Write the parameters in one line, you can modify excisting ones. Remember to reload config after parameters are changed with: sudo systemctl daemon-reload sudo systemctl restart rgc.service

i found another problem i think...after the "sudo bash rgc-setup.sh" command it says unable to locate package python systemd . i dont know if this is relevant...thanks for the help!!

arek125 commented 5 years ago

First of all you can't use port 22, it's ssh port already in use. Python systemd is nessesery. Use Backports or pypi to install it.

pav1996 commented 5 years ago

well i need to have a python version of 3.4 or bigger to install systemd but every (working)way i tried doesnt solve the problem....python is updated but the message stil says that i need 3.4 or bigger

arek125 commented 5 years ago

No you don't need python 3, server app is using python 2. Install this package: https://github.com/systemd/python-systemd If you have raspbian(debian streach), add backports to get commad apt-get install python-systemd to work, or install from source like above link shows. Here is instruction how to add backports: https://stackoverflow.com/questions/52700155/adding-debian-9-stretch-backports-to-my-sources-list

arek125 commented 5 years ago

OK, if you installed from source then remove python-systemd from rgc-setup.sh file and run it again.

arek125 commented 5 years ago

This looks like python-systemd is still not installed. Try to install it from backports: https://backports.debian.org/Instructions/

arek125 commented 5 years ago

Here is detailed instructions how to add backports:

1.sudo nano /etc/apt/sources.list 2.Paste line: For stretch: deb http://ftp.debian.org/debian stretch-backports main For jessie: deb http://ftp.debian.org/debian jessie-backports main 3.sudo apt-get update IF GPG key ERROR: 4.sudo apt-get install dirmngr 5. gpg --keyserver pgpkeys.mit.edu --recv-key 8B48AD6246925553
gpg -a --export 8B48AD6246925553 | sudo apt-key add - gpg --keyserver pgpkeys.mit.edu --recv-key 7638D0442B90D010
gpg -a --export 7638D0442B90D010 | sudo apt-key add -

  1. Then: sudo apt-get update sudo apt-get install python-systemd
pav1996 commented 5 years ago

now this W: GPG error: http://ftp.debian.org jessie-backports InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8B48AD6246925553 NO_PUBKEY 7638D0442B90D010

Look at pkt 4,5 of above instruction.

pav1996 commented 5 years ago

address unreachable both from phone and windows (didnt understand that i have to ping from the phone) is it a router problem? maybe a security option i can change? btw from pc it transferred me in a page with your app logo asking for password then when i pressed it gave me a status code 402

pav1996 commented 5 years ago

pav1996 commented 5 years ago

ohhhh fucking finally it works thanks a lot man for baring with me!!!! any way to donate to you for this 8 hours of help?

arek125 commented 5 years ago

Sure, donates are very much appreciated. Thank you in advance. Paypal link

pav1996 commented 5 years ago

ok one last thing!! i know downloading scripts and apps to make new stuff isnt gonna help me much....i want to make my own app to control my rpi remotely (mostly for home automation projects i am working on ) and i have been told to use an app called android studio.... what it your opinion for this app and if its bad can you recommend smth else?

arek125 commented 5 years ago

When it comes to writing applications for android, Android studio is the only right choice for now. It allows programming in java/kotlin. But this applies only to the android client. You must write the server application in a different language.
