ifup will not work with wireless, you should rather use iwconfig wlan0.
On my system, sudo rfkill unblock 0 followed by iwlist wlan0 scan works fine. There's no need for sudo in the second command. It could be that you have installed several network managers at the same time, or using the wireless interface in AP mode.
There are several ways to do this. I would install
apt install openssh
on the pi. And use the command in terminal:
Next step would be using the "get" command and the path to your Storage. This works vice versa from PC to Raspberry or Raspberry to PC.
But that is for a single transfer via Terminal for your 100GB files. ...
I ran the aircrack program with my raspberry pi 4 8 gig approximately 1 week ago. I had no issues setting the wireless antenna into monitor mode.
Then again I was running Kali off the pi hardware. Although that shouldn't matter I don't think.
You have a 0.0.0.0 to the 192.168.3.0/24 network and 0.0.0.0 implies there is a way to internet through the 192.168.3.0/24 network.
And 0.0.0.0 via eth0 is chosen because a Ethernet port has a lower metric than WiFi. Use the route command without -ne will show the metric values for the ports. Low metric is preferred over a higher one.
So by reading the last line of my post, it raised a question in my head:
When the RPI and the PC are connected together with an ethernet cable, Wireshark throws these messages from the raspberry:
Who has 192.168.1.1? Tell 192.168.1.126
Why is the raspberry trying to find the router? there isn't one..
I manually set the dhcp settings of my computer in ...
This sounds like a issue with the access from external.
What is the difference between the two Raspberry Pi's you can access from external and the five Pi's who are not able the be accessed from external? Are they the same hardware? Are the 5 Pi's are clones?
When you can access all from the office (same wifi) it has to be an issue with incoming connections ...
I ran into this issue recently, my old Raspberry Pi became my FreeRadius server and so I set it up with a static IP.
The relevant information from PhillipB's Python script turned out to be running ip addr flush on the interface in question, eth0 in my case. Just restarting dhcpcd.service didn't help.
So here's the simplified solution in my case:
To change the WiFi of a headless Raspberry Pi, switch off the Pi and remove the sd card. Put the SD card in a PC. You will see a boot partition show up and you can put a file named wpa_supplicant.conf under root folder of this partition with the updated wifi information. The Raspberry Pi will automatically load this file upon boot.
Here is a sample ...
I suggest that rather than trying to set a static IP Address you request the DHCP server to assign a predictable IP Address. See https://raspberrypi.stackexchange.com/a/121830/8697
The Pi WILL "work out of the box" - it is designed to use DHCP.
The values you are are attempting to assign seem to be inconsistent with your router, but you haven't ...
This issue has persisted with Big Sur. In hunting around, the solution may be to add/edit to your ~/.ssh/config file on your Mac the following:
The reasoning for and source of this proposed answer can be found here:
All works correct now. Thanks for the help.
The steps I took to fix it was
use the ether MAC address under eth0
Manually configure a static on the router/modem.
Restart the RPi. service networking restart did not do it for me.
First thing to do is remove the file you created in /etc/network/interfaces.d - you rarely (if ever) need to touch anything in /etc/network folder ... if you read /etc/network/interfaces you'll see the following:
# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/...
I had this issue with a Raspberry Pi 4 w/ 7" touch display, powered via PoE HAT. My SSH sessions would disconnect, leaving the SSH (sshd) process still running on the RPi, leaving me to believe it was a hardware or power issue.
