Can't share connection on MacOS Catalina

[Niubbo75]

I've create a folder in /home/pi named scripts, there I've put macos_connection_share.sh I've made it executable running chmod a+x macos_connection_share.sh Next I've run the script, both from pi user and root but I got the same issue:

pi@pwnagotchi:~/scipts $ ./macos_connection_share.sh ifconfig: option ``-lu' not recognised. ifconfig: ``--help' gives usage information. can't find usb interface with ip 10.0.0.1 pi@pwnagochi:~/scipts $ sudo ./macos_connection_share.sh ifconfig: option ``-lu' not recognised. ifconfig: ``--help' gives usage information. can't find usb interface with ip 10.0.0.1

What can I do to fix it?

Steps to Reproduce (for bugs)

1. Create or download macos_connection_share.sh from github
2. Made it executable
3. Run it with ./macos_connection_share.sh
4. Look at the output

Your Environment

• [ ] Latest pwnagochi image downloaded from official repository

• [ ] Raspberry Pi0 W

• [ ] MacOX 10.15.7

The connection sharing script has to be executed on the device from which you want to share the connection, not on the Pwnagotchi/RaspberryPi. So in your situation you'll have to execute it on your Mac.

Hello, sorry for the delay in my reply, but I have try it only now. I've run the script on my Mac (now upgraded to Big Sur), I had run it with sudo but I can't share connection anymore, plus, when I connect also my Pi, I can't surf the net (ping google.com or 8.8.8.8 gave only unreacheable destinations both from Pi and Mac). Should I have to change something in the script?

I am struggling with the same issue, any update OP ?

Same issue here. I'm figuring why.

Here is excerpt of ifconfig on my Macbook. I have both Wi-Fi, ethernet and usb with pi zero w connected on my Macbook. The interface of usb (en14) has been manual setted at 10.0.0.1 by me.

$ ifconfig
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=400<CHANNEL_IO>
	ether xx:xx:xx:xx:xx:xx
	inet6 xxxx::xxx:xxxx:xxxx:xxxx%en0 prefixlen 64 secured scopeid 0x6
	inet6 xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx prefixlen 64 autoconf secured

	nd6 options=201<PERFORMNUD,DAD>
	media: autoselect
	status: active
en7: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=6407<RXCSUM,TXCSUM,VLAN_MTU,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM>
	ether xx:xx:xx:xx:xx:xx
	inet6 xxxx::xxx:xxxx:xxxx:xxxx%en7 prefixlen 64 secured scopeid 0x15
	inet6 xxxx:xxxx:xxxx:xxxx:xxx:xxxx:xxxx:xxxx prefixlen 64 autoconf secured
	inet6 xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx prefixlen 64 autoconf temporary
	inet 192.168.100.102 netmask 0xffffff00 broadcast 192.168.100.255
	nd6 options=201<PERFORMNUD,DAD>
	media: autoselect (1000baseT <full-duplex>)
	status: active
en14: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	options=6407<RXCSUM,TXCSUM,VLAN_MTU,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM>
	ether xx:xx:xx:xx:xx:xx
	inet6 xxxx::xxxx:xxxx:xxxx:xxxx%en14 prefixlen 64 secured scopeid 0x17
	inet 10.0.0.1 netmask 0xffff0000 broadcast 10.0.255.255
	nd6 options=201<PERFORMNUD,DAD>
	media: autoselect (100baseTX <full-duplex>)
	status: active

Then here is result of macos_connection_share.sh on my Macbook.

$sudo ./macos_connection_share.sh
Password:
sharing connecting from upstream interface en0 to usb interface en14 ...
net.inet.ip.forwarding: 1 -> 1

Then testing is no work on Pi via ssh through usb.

pi@pwnagotchi:/ $ ping 8.8.8.8

I don't know how helpful this will be, but 1. this issue seems to go back to the first Pwnagotchi release - lots of reddit posts about getting connection sharing to work on a mac.

You could look into going into system prefs > sharing and turning on internet sharing to see if that changes anything. (I actually think you need to for bluetooth? That's a separate issue).

Googling No ALTQ support in kernel brings up some StackExchange posts regarding PFSense throwing this issue. One suggestion says to go into System Prefs > Security & Privacy > Firewall and turning the firewall on. I haven't tried this yet, however, so ymmv.

A slightly separate solution I saw for the linux_connection_share.sh was to declare the interfaces you want share. For instance, sudo ./linux_connection_share.sh [Pwnagotchi Interface Name] [Upstream Interface Name] Eg. sudo ./linux_connection_share.sh enp0s20f0u2 wlo1 That suggestion was from this post..

If you have any linux machines available, I have had very a very steady working Pwnagotchi when setup, configured, and connected to kali linux. But every time I try to on my mac, I'm met with issues. I would love to see if someone has a succinct solution for this that works for everyone.

I'm also having trouble getting the Pi 0 connected to the internet via MacBook. If I configure Bluetooth I can get it to use my phone data, but I'd like to use my laptop on Wi-Fi so I can install a version of Numpy that allows the AI to work, as well as fix the expired apt signing key.

It's also worth noting that I was able to share internet using a Raspberry Pi 3B without issue via an ethernet cable.

Here's what I've tried so far:

Hardware

• MacBook Pro M1 (macOS 13.0.1 - Ventura)
• Raspberry Pi 0 w with a fresh image
• USB Data Cable

First Attempt

1. System Preferences > Network > RNDIS/Ethernet Gadget > Details
   • TCP/IP
     • Configure IPv4: Manually

     • Router: 10.0.0.1
2. System Preferences > General > Sharing > Internet Sharing: Toggle ON
   • Share your connection from: Wi-Fi
   • To computers using: RNDIS/Ethernet Gadget
3. Plug in completely fresh Pwnagotchi
4. Run sudo ./macos_connection_sharing.sh en0 en7

   sudo ./macos_connection_share.sh en0 en7
   Password:
   sharing connecting from upstream interface en0 to usb interface en7 ...
   net.inet.ip.forwarding: 0 -> 1

1. Once booted
   • My laptop internet stops working
   • I'm unable to SSH into the Pwnagotchi

Ha, of course after I finally write out the post I figure it out.

Solution

1. Plug in Pwnagotchi
2. System Preferences > Network > RNDIS/Ethernet Gadget > Details
   • TCP/IP
     • Configure IPv4: Manually
     • IP address: 10.0.0.1
     • Subnet Mask: 255.255.255.0
     • Router: 10.0.0.1
3. System Preferences > General > Sharing > Internet Sharing: Toggle OFF
4. HERE'S THE TRICK: System Preferences > Network > Hit the "... V" looking button and choose "Set Service Order". Make sure Wi-Fi is above RNDIS/Ethernet Gadget
5. Run sudo ./macOS_connection_share.sh en0 en7

[rinchen]

NB:

• The connections in step 5 in the previous comment should be confirmed by the user by doing an ifconfig. en0 is likely always correct but en7 will be highly user-dependent (it is en11 in my case). To find this, look for the 10.0.0.1 IP address assigned to the interface.
• Enabling the sharing script disabled iCloud Private Relay. To fix this,
  • sudo sysctl -w net.inet.ip.forwarding=0 (You could skip this but in the interest of completeness it's here)
  • sudo pfctl -d (This disables packet filtering and re-enables Privacy Relay)

So I did everything you said @rinchen in your post and it seems you'll get the error No ALTQ support in kernel ALTQ related functions disabled regardless. I did notice that net.inet.ip.forwarding: 1 -> 1 changed from 0 -> 1 and it does work now. I haven't checked if it still works after a reboot though, but thanks for your solution
