status mpradio
Closed this issue · 15 comments
Hi morro,
today i've re-installed your mpradio on RPI Wifi Zero. I think there is an error on /etc/profile
sudo systemctl status mpradio

Yup, I've yet to debug it, and it's strange since /etc/profile is not installed/modified by mpradio itself

so.. basically you removed the "sbin" directories from the PATH in /etc/profile?
could you check for me the output of:
$ which id and $ whereis id
pi@raspberrypi:~ $ which id
/usr/bin/id
pi@raspberrypi:~ $ whereis id
id: /usr/bin/id /usr/share/man/man1/id.1.gz
pi@raspberrypi:~ $
My default /etc/profile

# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).
if [ "`id -u`" -eq 0 ]; then
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games"
fi
export PATH
if [ "${PS1-}" ]; then
if [ "${BASH-}" ] && [ "$BASH" != "/bin/sh" ]; then
# The file bash.bashrc already sets the default PS1.
# PS1='\h:\w\$ '
if [ -f /etc/bash.bashrc ]; then
. /etc/bash.bashrc
fi
else
if [ "`id -u`" -eq 0 ]; then

if [ -d /etc/profile.d ]; then
for i in /etc/profile.d/*.sh; do
if [ -r $i ]; then

done
unset i

Why have you deleted the last comment?
simply because each time i reinstall the mpradio the /etc/profile return to default settings.
I solved the boot error by editing the /etc/profile as described here:
https://askubuntu.com/questions/998503/bash-id-command-not-found
If i stop and start the mpradio, the service start without any error with the default /etc/profile. But anyway in both cases i can't hear any sound on 88.8Hz
pi@raspberrypi:~ $ sudo /bin/bash -l -c /home/pi/mpradio
SSH is enabled and the default password for the 'pi' user has not been changed.
This is a security risk - please login as the 'pi' user and type 'passwd' to set a new password.
107.0

At first sight, it doesn't seem like a mpradio problem to me, but rather a raspbian 9 configuration issue. Good to know there is a simple solution thought.
as for the second issue: have you plugged an antenna on GPIO's pin 4? if you don't you won't have enough transmitting power to reach your FM receiver
PS: i see the frequency is set to 107.0 from your command line
strange Morro, i didn't touch nothing, https://github.com/morrolinux/mpradio/blob/master/install/pirateradio.config as you can see is your config file :) now working on 107.0Hz with a small antenna
let me know if you solved :)
PS: in /etc/profile you could also just edit the line:
if [ "id -u" -eq 0 ]; then
to
if [ "/usr/bin/id -u" -eq 0 ]; then
This is happening because id (/usr/bin/id) is not in the PATH of the user executing /etc/profile upon login. shouldn't compromise mpradio's functionality anyways.
Morro solved, it is on 107.0 Hz no 88.8 :) regarding the /etc/profile didn't solved.
Alright!
the /etc/profile error is safe to ignore at the moment, as it doesn't interfere with mpradio's functionality and it's more a debian/user related issue rather than the coding itself.
Be aware that this will probably be gone in the future as I'm planning to launch the service with a different user, set different permissions, etc etc..
