Pidora not starting on reboot and other issues

[taylorkline]

Hello again! Entirely possible this is my fault again, but right now Pidora isn't restarting. When I restart my RPi and go to IPADDRESS:8080, nothing is being hosted unless I run python ./pidora/hello.py manually. Maybe it's a problem with:

echo "rm $HOME/pidora/curSong.json
@python $HOME/pidora/hello.py
@midori -a \"http://localhost:8080/\" -e Fullscreen" | sudo tee -a /etc/xdg/lxsession/LXDE/autostart

Could it be a problem with the fact that I have a headless install and do not use LXDE?

Also, when I start Pidora manually with python ./pidora/hello.py and access it from my laptop's browser (Chrome), I get stuck with "Pianobar is starting up" and eventually the ssh session ends with an error:

Thanks in advance for your help.

I've seen other people have this same issue, and I simply haven't seen it yet. I'm not going to say it's unreproducible yet because I'm going to try wiping the Pi and installing from install.sh and maybe that'll produce the bug.

Can you give me an update on this? Is it still occurring?

[taylorkline]

Yes, I was unfortunately never able to determine the cause.

[jacroe]

You wouldn't happen to know of anything else on your Pi that's already using port 8080 do you?

[jacroe]

It looks like port 8080 is already bound to by some other program/service. You could try using a different port number (anything over 1024) by changing it in cpy.conf and bar-update.py. And then running python hello.py. If it's a port binding issue, that would (read: should) solve it.

[taylorkline]

I'll try that next week over spring break and report back!

Unfortunately, no luck with that:

I had a similar issue where it wouldn't start at startup because the network stack wasn't fully initialized; I wrote a little start-pidora script that was:

#!/bin/bash
export PATH=${PATH}:/usr/local/bin
while ! ping -c 1 8.8.8.8 >/dev/null 2>&1 ; do
  sleep 1
done
cd /home/pi/pidora
python hello.py >/tmp/pidora.log 2>&1 

Which fixed it for me. YMMV.
