Как найти малину в сети

#40044978

Все малиновые устройства MAC-адреса начинаются с B8: 27: EB .

Таким образом, в системах * nix это можно выполнить, выполнив следующую команду:

где 192.168.1.*будет ваша маска локальной сети. Вы получите ответ, как:

192.168.1.179 – это IP-адрес Raspberry Pi в вашей сети.

Если вы используете систему Mac , вы можете использовать Homebrew для установки nmap :

В Windows вы можете использовать Wireshark и использовать следующий фильтр отображения:

By default the raspberry’s name is raspberrypi. You can just ‘ping raspberrypi’ and the ICMP echo reply gives you the IP address. It worked for me. Make sure though the DHCP server is reachable as the raspberry’s NIC is by default in DHCP client mode. Otherwise the raspberry gets an APIPA address.

In 2020, the accepted answer does not work anymore because the Raspberry Pi ships with a different range of MAC addresses. I could just add the “new” MAC as a comment, but the string could change again and again each model. Here is something that’s more future-proof.

$ sudo nmap -sP 192.168.150.0/24 |grep 'Raspberry Pi Trading' -B2
Nmap scan report for pi4-01.lan (192.168.150.186)
Host is up (0.037s latency).
MAC Address: DC:A6:32:1B:35:6A (Raspberry Pi Trading)

The main difference above: we don’t assume a MAC pattern, we just grep for the (summary), as this label is provided by nmap itself. Because nmap is continually updated, it contains internal tables of Raspberry Pi MAC addresses (or uses other criteria to detect) and we can assume that will continue working.

CAVEAT: If your scan does not identify all Pis you know are on the network, then repeat the scan — up to 10 times. A Pi which has networking Power Management:on might not always respond to a scan.

Power Management may be a problem for you if you are scanning for multiple Pis on a LAN, as repeat scans might detect one Pi but not another. In that case, repeat the scans look for differences. (To confirm if a Pi has Power Management enabled, ssh to the Pi and run: /sbin/iwconfig wlan0|grep Management)

Copy the following into your Terminal/Console/Shell:

for i in $(jot - 1 254); do ping -t 1 192.168.1.$i && arp -a | cut -f 2,4 -d " " | tr [:lower:] [:upper:] | grep B8:27:EB; done

Please adapt 192.168.1. to your individual network.

The output will look something like this:

(192.168.1.109) B8:27:EE:DD:CC:A

192.168.1.109 would be your Raspberry Pi’s IP… 🙂

Put this in pi.php on your web server:

<?php
$fp = fopen('pi', 'w');
fwrite($fp, $_REQUEST['ip'],1000);
fclose($fp);
?>

You may have to create the file pi on your web server with write permissions for your web server.

Put

curl http://yourwebserver/pi.php -d ip=`hostname -I`

in /etc/rc.local on your pi.

Get the IP of your pi by browsing http://yourwebserver/pi

My router assigns newly discovered systems an ip-address starting at 192.168.1.2, sequentially. I went through every system in my home one day and reserved addresses for them.

That way when I create a new system, chances are that its ip-address will be 192.169.1.18.

Another way to use the serial console. You can use a serial terminal program in order to log into your raspberry pi. I would suggest using the 8N1 (8-bits, no parity bit, 1 stop bit) setting with a speed (baud rate) of 115,200. You’ll need a USB to serial (3V3) connector.

If you are on Windows I suggest you to try out this script.
It is mostly based on the “arp -a” command, but it saves you some extra digging and helps you when your Raspberry Pi is not already in the Arp table.

Create a text file with the following content and rename it as find_raspberry_pi.bat

@echo off
:: This script, run from a Windows (10) machine, finds a Raspberry Pi on local network

:: You can manually set subnet if needed
:: E.g.
::SET subnet=192.168.56
SET subnet=

:: --- No need to edit below this line ---

SET raspIp=
SET myip=

:: Get IP for local PC
FOR /f "tokens=1-2 delims=:" %%a IN ('ipconfig^|find "IPv4"') DO SET myip=%%b
SET myip=%myip:~1%
echo IP for local PC: %myip%

:: Retrieve subnet if not manually set
IF "%subnet%" == "" (
    SETLOCAL EnableDelayedExpansion
    SET subnet=%myip%
    FOR /l %%a IN (1,1,31) DO IF NOT "!subnet:~-1!"=="." SET subnet=!subnet:~0,-1!
    SET subnet=!subnet:~0,-1!
    SETLOCAL DisableDelayedExpansion
)

:: Show subnet
echo Subnet: %subnet%
echo.

:: Loop through arp table entries and look for Raspberry Pis MAC addresses
echo Discovering network...
:: Ping all IPs in subnet from 1 to 254
FOR /L %%N IN (1,1,254) DO start /b ping -n 1 -w 200 %subnet%.%%N >nul
timeout 1 >nul
FOR /f "tokens=1" %%f  IN ('arp -a ^| findstr "28-cd-c1 b8-27-eb e4-5f-01 dc-26-32"') DO (
    IF NOT "%%f"=="" echo Found Raspberry Pi having IP %%f
)
echo.
pause

Disclaimers:

1. I am not the author of the original script, I just adapted it a little bit to work with a Raspberry Pi. Sadly, I cannot find the original contributor.
2. It’s not bullet-proof, it will not work if the subnet it starts scanning is not the correct one if you want to scan a different subnet you need to manually edit the appropriate line at the beginning of the script.

UPDATE 2022:

I updated this script. Now:

• it can find multiple Raspberry Pis at once
• it can find allegedly all types of Raspberry Pis (3, 4, etc.)
• you can manually force a specific subnet if the autorecognize feature finds the wrong one

Raspbian is using a thing called mDNS, which allows you to access your raspberry pi by a hostname raspberrypi.local.

So, you don’t need to search for an IP address anymore, just connect like so:

ssh pi@raspberrypi.local

I assume you cannot connect to you PI, otherwise you’d know its IP.

If you go to your router page (usually something like 192.168.1.1 in your browser) there you should have a section with the already connected devices. You can try to plug and unplug the PI (and one device should appear / dissapear from the list)

I wrote myself a bash script to find my OctoPi a while ago.
You can change the systype=”Raspberry Pi” to whatever type of device you are looking for. It finds the subnet itself so you need not guess 192.168.1.0 or whatever.
There are now 3 different OUI ranges for the Pi Foundation:
https://udger.com/resources/mac-address-vendor-detail?name=raspberry_pi_foundation

B8:27:EB:xx:xx:xx   B8-27-EB-xx-xx-xx   B827.EBxx.xxxx
DC:A6:32:xx:xx:xx   DC-A6-32-xx-xx-xx   DCA6.32xx.xxxx 
E4:5F:01:xx:xx:xx   E4-5F-01-xx-xx-xx   E45F.01xx.xxxx 

So the ping grep answers need to add those

[andy@localhost ~]$ sudo ./findpi.sh

My address is wlp0s20f3:192.168.68.128

Found 1 Raspberry Pi system 
    Raspberry Pi system found at 192.168.68.124

I fixed it up a little and here it is:

   do

exit 0
