I have been handicapped by the GUI and always seem to ask of help when it comes to the command line.
On Mac OS X only I need a command line to get the mac address of the wifi currently in use.
Help!
ifconfig en1 gets the interface details for wifi, the mac is on a line starting with ether, and is the second word on that line so:
ifconfig en1 | awk '/ether/{print $2}'
I think the best and easiest way to get the information is using this command:
networksetup -listallhardwareports
It will return a nice list of devices like this:
Hardware Port: USB 10/100/1000 LAN
Device: en6
Ethernet Address: 00:e0:4c:...
Hardware Port: Wi-Fi
Device: en0
Ethernet Address: 80:e6:50:...
Hardware Port: Bluetooth PAN
Device: en3
Ethernet Address: 80:e6:50:...
Hardware Port: Thunderbolt 1
Device: en1
Ethernet Address: 72:00:05:...
Hardware Port: Thunderbolt 2
Device: en2
Ethernet Address: 72:00:05:...
Hardware Port: Thunderbolt Bridge
Device: bridge0
Ethernet Address: 72:00:05:...

===================
networksetup -getmacaddress <interface>
Wifi mac address is normally can be found in en0. So you may try this command on Terminal
ifconfig en0 | awk '/ether/{print $2}'
ifconfig should do the trick, it'll display a bunch of info including your MAC address. Alternatively it'll be in your network settings under system preferences.
EDIT
On a computer with just a wireless connection, en0 will have your wifi settings. The tag labeled with ether will most likely be your MAC address.
If you have both a wired and wireless connection, it'll be under ether in the en1 tag

This will easily give you the specific Mac Address for your Wifi Interface
networksetup -listallhardwareports | grep Wi-Fi -A 3 | awk '/Ethernet Address:/{print $3}'

in Windows i'm using as below.
netsh wlan connect ssid=YOUR-WIFI-SSID name=PROFILE-NAME
Need similar for the mac os.
I think it will depend on whether you have saved the WiFi password in your keychain but the basic command is networksetup as follows:
networksetup -setairportnetwork en0 YOUR_NETWORD_SSID
For more information, try:
man networksetup
I have a sensor device connected to my Ubuntu 20 machine using a serial to usb cable. I understand that to stream data from it I need to run the following commands:
Enter root with sudo -I.
Setup a virtual COM port with stty -F /dev/ttyACM0 9600 cs8 -cstopb -parenb.
Send a command to the device to initiate data streaming with echo -e "some_string" > /dev/ttyACM0.
Stream data with cat < /dev/ttyACM0.
However, I cannot be sure that my device is connected as /dev/ttyACM0. How can I set this up? Currently it has the path /dev/bus/usb/001/005, although the last number changes every time the device is plugged in.
In response to the comment below, here is the output I get when I disconnect the device and run dmesg | tail (I've edited some real values):
[89092.291151] usb 1-1: USB disconnect, device number 11
[89100.310893] usb 1-1: new full-speed USB device number 12 using xhci_hcd
[89100.467562] usb 1-1: New USB device found, idVendor=SOME_ID, idProduct=SOME_PRODUCT, bcdDevice=SOME_BCD_DEVICE
[89100.467565] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[89100.467567] usb 1-1: Product: SOME_PRODUCT
[89100.467569] usb 1-1: Manufacturer: SOME_MANUFACTURER
EDIT: I have just found that I can use sudo modprobe usbserial vendor=SOME_ID product=SOME_PRODUCT to make ttyUSB0 available. However, plugging this into the above commands and running screen /dev/ttyUSB0 only returns lots of ``` characters. Note that this stops when the device is unplugged.
I managed to get this working. The commands were:
sudo -i
rmmod ftdi_sio
rmmod usbserial
modprobe ftdi-sio
echo -n VENDOR_ID PRODUCT_ID | sudo tee /sys/bus/usb-serial/drivers/ftdi_sio/new_id
stty -F /dev/ttyUSB0 9600 cs8 -cstopb -parenb
echo -e "uud1\r" > /dev/ttyUSB0
screen /dev/ttyUSB0 9600
I'm building a tool to manage DNS in macOS.
I know how to set dns server in terminal.
networksetup -setdnsservers Wi-Fi 1.1.1.1
but I don't to know how to unset it, or set it to the default value
networksetup -setdnsservers Wi-Fi
seems not working.
Anyone help ?
Give a try to:
networksetup -setdnsservers Wi-Fi empty
Then check with:
scutil --dns
From man networksetup:
-setdnsservers networkservice dns1 [dns2] [...]
...
If you want to clear all DNS entries for the specified network service,
type "empty" in place of the DNS server names.
I'm making a mac os app. I'm trying to get the ethernet and wlan addresses. I know these are en0 and en1 addresses but depending on devices, en0 can be the ethernet or the wlan one. Is there a way to know which one it is?
So far I'm using this which gets me both addresses but don't differentiate them:
let task=Process.init()
task.launchPath="/sbin/ifconfig"
task.arguments=["en0"] //or en1
let pipe=Pipe()
task.standardOutput=pipe
task.launch()
let data=pipe.fileHandleForReading.readDataToEndOfFile()
guard let stringResult=String(data: data, encoding: String.Encoding.utf8) as NSString? else{wlanFailed();return}
print("en0:", stringResult)
EDIT
So now I'm trying to run this command networksetup -listnetworkserviceorder which works from my terminal.
But I don't know how to make it work from my Mac app. For example, with this:
let task=Process.init()
task.launchPath="/sbin/networksetup"
task.arguments=["-listnetworkserviceorder"]
I get:
launch path not accessible
These are some commands that help to match the interface with the hardware name:
networksetup -listallhardwareports
networksetup -listnetworkserviceorder
system_profiler SPNetworkDataType
scutil <<< "list" | grep -i airport
Thanks #artem-dorodovskiy and #nbari for giving me the command line.
I found how to write it thanks to this SOF answer.
let task=Process.init()
task.launchPath="/usr/bin/env"
task.arguments=["networksetup", "-listnetworkserviceorder"]
I wrote the following BASH script to change my MAC address back to the normal one after I am done using a spoofed MAC address:
sudo ifconfig en1 ether 00:11:22:33:44:55
It works. However, the following code doesn't work:
mac=$(cat /volumes/KYLE-OSX/mac.txt)
sudo ifconfig en1 ether $mac
I am given the following error message:
ifconfig: can't set link-level netmask or broadcast
I am unable to predict what the MAC address is going to be, so I need to be able to use any possible MAC address in the 'sudo ifconfig en1 ether' statement.
The fundamental problem was diagnosed in comments already -- the file contains more than just the MAC address. Here's a simple workaround for that.
mac=$(grep -Eo '\<[0-9a-f]{2}(:[0-9a-f]{2}){5}\>' /Volumes/KYLE-OSX/mac.txt)
