To make a man in the middle attacker with a Raspberry Pi 3B(+) or 4B is very simple. You will use an additional USB/ethernet dongle so you have a second wired interface eth1 available. Now just bridge eth0 and eth1 and you have a complete transparent and stealth device. Start with a fresh flashed image Raspbian Buster Lite and use systemd-networkd to set it ...

I have a Pi 4 Model B/4GB serving a small office as a router/firewall/gateway with dnsmasq (DHCP+DNS), dnscrypt-proxy, chrony (NTP), and a few other odds and ends. It's fairly busy: up to 20 users at a time, lots of file uploads, three main VLANs (plus a management VLAN). There's minimal internal routing for the time being. I haven't really stress-tested ...

The Pi and the laptop are on different networks. I suggest setting a static address in the 192.168.8.0/24 subnet on the Pi. You'll need to use one that hasn't been assigned by the DHCP server on your network. Alternatively, since it seems that the laptop's address was set manually, you could set an address in the link-local network (169.254.0.0/16) on the ...

To elaborate the answer from @Ingo: please consider using the link ln -s /run/systemd/resolve/stub-resolv.conf resolv.conf instead of the link to /run/systemd/resolve/resolv.conf. This enable the "integrated" DNS stub and enables things like per-interface DNS server which could be important if you use VPNs that provide their own DNS server with non-public ...

I borrowed the RPI 3B from a friend's friend. hence I don't know the hostname so that I can ping the RPI to know its IP address. Raspberry Pi is a board without any internal storage hence it doesn't matter where you got this. You installed your own operating system (a downloaded image file) on the SD-Card and because of that, you have formated (remove any ...

If you are open to use another modern all-in-one networking environment without needing additional helpers like hostapd, dnsmasq or bridge utils you can use systemd-networkd. It makes life easier. It is part of the default Raspbian image and you only have to enable and configure it. Here is a tested and working setup for what you want to do: Configuring ...

The below script can be used to find any vendor by Mac: Raspberry Pi or otherwise. Just supply the vendor's name as it's specified in the IEEE's MAC DB: "http://standards-oui.ieee.org/oui.txt" in the variable "VENDOR" and of course replace the echo's in the conditional expression with something useful. In its' present form it's meant to execute locally ...

There is a option on the raspi configurations to NOT wait for a ethernet connection to establish and just boot normaly. Its a checkbox. Hope it helps someone

This is a typical use case for dynamic failover. This will configure both interfaces eth0 and wlan0 and use one primary interface that you can define. if this connection fails it will automatically use the other interface as fallback. How to setup this you can look at Howto migrate from networking to systemd-networkd with dynamic failover.

In your netplan folder try deleting or commenting in your .yaml file the lines related to the MAC info: network: version: 2 ethernets: eth0: addresses: [yourIP/24] gateway4: yourGateway match: #Comment or delete macaddress: yourMacAddress #Comment or delete set-name: ...

The setting on the RasPi is OK so far. You do not need iptables rules pi@raspberrypi:~ $ sudo iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT pi@raspberrypi:~ $ sudo iptables -A FORWARD -i eth0 -o wlan0 -j ACCEPT but they don't hurt. It's all ACCEPTed in the FORWARD chain. But I would not set more than needed. The quirks is on the PLC. It receives packages ...

By the time you have bought the voltage converters (Ethernet runs at +2.5v, +1v, 0v, -1v and -2.5v depending on the speed) it would just be cheaper to buy an SPI based connector such as the Arduino ENC28J60. The issue you will then get is that this will be about 1/10 the speed of the Pi Ethernet port as a max... Even then, you adding a total pain into the ...

The Raspberry Pi 4 has DC:A6:32:xx:xx:xx (Raspberry Pi Trading) according to the Raspberry Pi Forums.

After some years there have been found a solution to this specific problem with Raspberry Pi. You very clearly described that you want to have a bridge on the RasPi but this cannot be done with a WiFi client connection to the router. For this it must supported by the WiFi chip but it doesn't. For further information about this look at Raspberry Pi WiFi to ...

First there is no need to worry about the used ethernet cable. It doesn't matter if you use a straight forward or a cross over cable. Nearly all devices since years are able to detect this including Raspberry Pi. Because it is unclear what you want to do, I can only give some general ideas. What does it mean "sending a datastream"? Do you want to send data ...

Seems there are to many components that have to play together: dhcpcd, ifupdown, hostapd and maybe dnsmasq and bridge-utils. I have a suggestion to reduce complexity with using systemd-networkd. It is available by default on Raspbian and has everything built-in, no need to install any additional helpers. Here is a setup with a bridge that I have tested for ...

So I had this problem with an RP 4, within 5 mins the router would crash. As silly as it sounds, changing the network cable ro a different brand means its been running for around 5 hours with no crashes. Hope this helps

adding an IP to br0 solved this problem for me. thanks. raspbian 10.3: /etc/network/interfaces auto br0 iface br0 inet static bridge_ports eth0 wlan0 address 10.0.0.10 broadcast 10.0.0.255 netmask 255.255.255.0 gateway 10.0.0.1

The other user didn't really answer the question asked, about what usb to ethernet adapters work with the Raspberry Pi 4. Here are some forum links I found that may help. I don't have a RPi 4 myself (yet!) so I can't confirm, but it seems that most adapters will work fine, with maybe a slightly more limited speed. For physical devices what counts on Linux ...

If you have dnsmasq installed you can verify with: sudo netstat -laputeno|grep 67 If it is the case: sudo systemctl disable dnsmasq sudo systemctl stop dnsmasq sudo systemctl start isc-dhcp-server should work

Unless you have changed your router's IP address, neither of these look like a normal router address. 192.168.0.1 or 192.168.1.1 are more common: Google your router's name and "default IP address" to find out what it should be, then browse to that IP it to check it hasn't changed. If it really is 192.168.88.44 then your RPi static address will need to be ...

As far as I can tell from /boot/overlays/README you need to add the following entry in /boot/config.txt (and remove or comment out any existing enc28j60 entry). dtoverlay=enc28j60-spi2 From your forum link that should use chip enable 0. The relevant part of the README is: Name: enc28j60-spi2 Info: Overlay for the Microchip ENC28J60 Ethernet ...

What you want to have is a classical failover scenario. Fortunately Linux has a professional solution for it with bonding. With it you can combine two (or more) interfaces where you can configure what should be the primary interface and switch over to the reserved interface if the primary fails and switch back if the primary is available again. This all is ...

As you mentioned, it's easy to do it on Windows OS, however, it's a bit different on Raspberry Pi and Linux. I have looked up guides but they all seem to mention using the pi as a DHCP server, not too sure what I want/need this. In your situation, the phone is a device that has an internet connection. Obviously, the devices/clients must connect to ...

Assuming you're using the hardware mentioned in the "raspi.tv" article, the problem is that you're using an Ethernet straight-through cable when you need a crossover cable. Gigabit Ethernet ports have "auto-crossover"/"auto-uplink" functionality built in, so you can connect any two ports using any type of cable, but older hardware, like the 10Base-T ...

It appears that it was sufficient to add the AllSlaveActive=1 option to the 02-bond0.netdev file described in @Ingo answer. In this way the ARP packet sent back by the router through the wlan0 interface is forwarded to the bond0 one and the ARP table is always populated. In order to set this parameter the restart of systemd-networkd.service was not enough, I ...

Connection drops after some time, inexplicably to me. It has happened because of your configuration since the network manager has changed on newer Raspbian. Please add the static IP according to the /etc/dhcpcd.conf for the eth0. Leave the /etc/network/interfaces with: # interfaces(5) file used by ifup(8) and ifdown(8) # Please note that this file is ...

It seems that you only found setups, using routing. But it is no problem to setup the WiFi access point on the RasPi to be on the same internal subnet as the internet router. You have to bridge the wired connection to the router on eth0 with the wlan0 interface of the access point. This way you are even on the same broadcast domain as the router, so your ...

If you only want to connect these two RasPis, then the simplest solution is to use the wired ethernet connection with just two static ip addresses. I assume interface enx0c5b8f279a64 on RasPi1 is that one from the USB LTE dongle. Now give its eth0 interface a static ip address, maybe 192.168.1.1/24. It must be different from the subnet 192.168.8.0/24 the USB ...
