Re: Problemas terminales

¿Pretendes que simplemente se ejecuten en el arranque los 2 comandos o quieres que se abra un terminal en la pantalla gráfica y que se ejecuten esos 2 comandos dentro de ese terminal?.

Re: Router Reset, Pi gone?

What do you mean by overlap? ANd yea I do have it manually setup to go to 192.168.0.50 [which is part of the pool that the router gives out to other devices but the router also has it set as a reserved IP for the Pi-Box] If you configure manually a static IP address on a computer (editing the file ...

Re: Router Reset, Pi gone?

Routers assign automatically an IP address to those computers or devices that have a DHCP client. A pool is used for that purpose. The pool defines a range of IP addresses (for example, 192.168.0.50-192.168.0.254). If you do not want to use DHCP, you can assign "manually" an static IP address to you...

Re: Mounting Pi 3 as network share for debugging.

Not sure if I understand your question. If you have a Linux machine and you wish to mount remote directories of your RPi, I recommend sshfs . You will have to install the package (this command will run on a debian distro) and add your user to the group fuse : sudo apt-get install sshfs sudo gpasswd ...

Re: Need a little help

I suppose that your RPi is connected via wifi.

Open a terminal and type these commands:

Code: Select all

iwconfig wlan0
ifconfig wlan0
ping -c4 8.8.8.8
ping -c4 google.com
Probably you will be not able to copy here their outputs but you can comment if they work properly.
