Creo que lo más fácil es que añadas al fichero /etc/rc.local tus comandos tal como los teclearías manualmente y en el mismo orden. Este fichero de comandos se ejecuta tras el arranque del sistema con privilegios de root , de modo que no debes preceder con sudo los comandos que añadas. Pon tus comand...

Maybe the problem is related to the micro SD card (for example, corrupt data due to an uncontrolled shutdown). I recommend to repair the two partitions ( vfat boot and ext4 root ) of the SD card. You will need a Linux system (PC, Live DVD, virtual machine, RPi, etc) for such procedure. If you have m...

Soy usuario habitual de Ubuntu MATE para PC, pero no lo he instalado en la RPi. No obstante, creo poder responder a tus preguntas: 1) De acuerdo a https://ubuntu-mate.org/raspberry-pi/ el tamaño mínimo de la tarjeta sería de 6GB. Pero, dado que no existen físicamente tarjetas de 6GB, en la práctica ...

ok...works...... but how/when running the script .... with cron job ? Richard Of course, you can use cron. Type the command: crontab -e For example, if you want to run your script every two minutes, add an entry like this: */2 * * * * /home/pi/ledcontrol.sh If you prefer a period lower than 60 seco...

This is a starting point for your script: #!/bin/bash ps -A | grep -q homebridge if [ $? -eq 0 ]; then echo "LED on" else echo "LED off" fi exit 0 If homebridge is running, the outputl will show LED on . If homebridge is not running, the output will be LED off . If you want to use this shell script,...

One question, Richard. How do you launch the program homebridge?.

Hi Richard,

what about this command?

Code: Select all

ps -ef | grep homebridge

lmarmisa

You will need to develop a script. This command will help: service --status-all | grep homebridge These other commands could be more useful: service --status-all | grep homebridge | cut -d' ' -f3 status=$(service --status-all | grep homebridge | cut -d' ' -f3) #the variable status will contain a cha...

Try this code: from datetime import datetime, date, time while True: now = datetime.now() usec = now.second * 1000000 + now.microsecond print(usec) If you prefer to get an string, try this alternative: usec = "%02d%06d" %(now.second, now.microsecond) NOTE: the range will be from 00000000 to 59999999.

I have just found out that I have to wait 5 minutes since I start my server. After this 5 minutes , I can synchronize my client using ntpdate: pi@client:~ $ sudo ntpdate -B 192.168.4.1 26 Jul 07:58:00 ntpdate[574]: adjust time server 192.168.4.1 offset 0.000033 sec Thanks for all the answers!

Hmmm. I think it's not a good idea to restart the service ( sudo service ntp restart ) and immediately look at its statistics ( ntpq -pn ). When you restart the service, the statistics are restarted too. :o Therefore, wait a few minutes and then type the two commands ntpq -pn . This link will help y...

I have tried to add another Raspberry as a client and when I do: sudo ntpdate-debian I do not know the command ntpdate-debian . Are you using a raspbian distro?. I believe that you need to install the package ntp on both RPis: sudo apt-get install ntp Then you have to configure the file /etc/ntp.co...

lmarmisa

These commands will be useful:

Code: Select all

ntpq -pn
timedatectl status

First step: check that the server is working properly.

Second step: verify the subnet between both RPis (use the command ping on both sides).

Third step: verify that the client is able to synchronize date/time with the server.

If in the console I type :~ $ motion the two errors happen If I type :~ $ sudo motion the program starts normally. This behavior is good.

La RPi 3B+ es muy puñetera con la alimentación y da muchos problemas incluso con alimentadores que dan un nivel de tensión adecuado y corriente suficiente. ¿Por qué pasa esto?.

I have checked here that the file /etc/default/motion should not include any blank space character. If motion detects a syntax error (blank space), the daemon is not started.

This is the correct syntax, not yours:

Code: Select all

# set to 'yes' to enable the motion daemon
start_motion_daemon=yes
