First setup

[etam]

Hi,

I am trying to run my raspberry pi through my macbook pro retina via ethernet (with a USB ethernet adapter) and have managed to turn on internet sharing and appear to establish a connection but then I don't know where to go from there. How do I login? I researched and found many places say go to terminal and type in ssh pi@ IP address but I just get "connection refused". HELP!

[B.Goode]

Welcome to the forums.

The sshd server (or Daemon or listener) on an RPi running Raspbian is disabled by default.

Have you taken any steps to enable it?

[etam]

I found sources suggesting I create a blank text file (using texteditor) named "SSH" to copy onto the microSD, removing the extension. I then reinserted the microSD and tried running the terminal command shown but it kept repeating that it wanted a password. I typed in my laptop password and the default pi password and neither worked.

If 169.254.253.226 is the local IP address of your RPi (how did you determine this?) then you have now made a connection to the RPi.

The password required is the current (not necessarily the default) password for the remote user specified in the connection request. For Raspbian the default is raspberry, just as it would be if accessing the RPi via a direct keyboard interface.

[etam]

That's the IP address that comes up when I go onto the network tab of system preferences. As you can see I tried typing in a password (raspberry) but it didn't work. Is there any other possible password it would be? Or is there something else I need to be doing?

[Ernst]

You are using a mac, something I know very little about.
But I do have this suspicion that you might be trying to setup an ssh connection to your Mac.
For a connection to work you need two IP addresses, one IP address on the source and another on the target.
You have found one IP address: 169.254.253.226, it is not clear if this is on the Pi or on the Mac.
This is a very special address (169.254.x.x) which is generated by the host if it can not obtain an address in any other way.
It is very likely that each interface has selected an address in that range, you will have to identify the address that has been configured on the Pi interface.
With my little knowledge of Mac I would say that you should be able to find the address with bonjour, maybe a ping using the name "raspberrypi.local" will show you the address to be used with ssh.

[B.Goode]

That's the IP address that comes up when I go onto the network tab of system preferences.

As @Ernst has said, that sounds as though you have asked your Mac to report what its own address is, and then made a 'loopback' connection to itself.

That isn't what you want to accomplish, and since there is probably no 'pi' user on your Mac there can be no corresponding correct password.

[etam]

The IP address I quoted is stated for the ethernet connection.

This is what comes up when I try to ping:

Elliots-MacBook-Pro-2:~ elliottam$ ping raspberrypi.local
ping: cannot resolve raspberrypi.local: Unknown host

[Ernst]

Disclaimer: I do not know much about Mac!

1) Is the red LED on the Pi on ?
2) Is the green LED on the Pi on ? Did you notice any activity on this LED ?
3) Are the LEDs on the Pi ethernet interface on ?
4) Have you tried another ethernet cable ?
5) What is the output of "ifconfig" on your Mac ?
6) What power supply are you using to power the Pi ?

Note: I am assuming that you are using a Pi with an onboard ethernet interface.

6) Not too sure but it's pi-branded

[B.Goode]

ping: cannot resolve raspberrypi.local: Unknown host

Disclaimer: I am not a Mac user - I am simply stating basic principles applicable to any OS.

The IP address you have discovered is almost certainly the address assigned to the Ethernet interface of your own Mac.

Maybe the internet sharing utility you have used has some sort of status or property page that would tell you what address has been assigned to the device (your RPi) at the other end of the Ethernet cable?

This is all assuming that you have no directly-attached display on the RPi and that you wish to operate it entirely 'headless' - that is perfectly possible, but as a new user it is less confusing if at the outset you can access the RPi directly.

You need to know whether the RPi is connected to the network cable and what address has been assigned to it by the connection sharing software on the Mac. There are a number of tools that might assist with that such as arp, nmap and Fing.

[B.Goode]

Note: I am assuming that you are using a Pi with an onboard ethernet interface.

Not too sure but it's pi-branded

So you are using a model of RPi without its own Ethernet interface?

Can you say anything further about this pi-branded Ethernet adapter? Do you have a link to the vendor website? Is it usb-connected to your RPi or to your Mac?

[etam]

What do you mean when talking about ethernet interface?

[Ernst]

Going through the ifconfig output I can only see horror !!! But that can be because I do not know Mac.
The first thing you must learn is to use code tags !!!!

I have a number of questions that need to be answered by either you or somebody else:

Is this your onboard ethernet interface on the Mac ?

Code: Select all

en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500

Which interface is the USB interface you use to connect to the Pi ?
Is this en1 or en2 ?
Now have a good look at the information below:

Code: Select all

en1: flags=963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX> mtu 1500

Do you notice that en1 and en2 are inactive and member of the bridge0 which is also inactive ?

Next, what is en5 ?

Code: Select all

which is the only member of bridge100

what a mess.

[etam]

I bought the pi to learn about coding, I know nothing.

The output I showed you is merely the output from terminal after typing in the command.

All I have done is connected an ethernet cable to the pi and then to a USB ethernet adapter to the laptop.

[B.Goode]

Maybe the bridge is a result of enabling internet connection sharing? (Just a guess, not a Mac user.. )

[etam]

I have enabled internet sharing, yes.

[B.Goode]

All I have done is connected an ethernet cable to the pi and then to a USB ethernet adapter to the laptop.

I understood you to say that the adaptor is pi-branded? Maybe it is not compatible with the Mac? (My understanding is that Apple are quite 'closed' in their attitude to external third-party hardware.)

[Ernst]

Please remove internet sharing and then do the following exercises:
1) Remove USB ethernet interface from your Mac and do an "ifconfig"
2) Plug the USB ethernet interface, without ethernet cable, into the Mac and do an "ifconfig".
Now compare the output of both commands and identify the interface
3) Plug the ethernet cable into the USB ethernet interface and the Pi, do an "ifconfig"
Look at what the differences are on the interface identified in 2)
Try "ping raspberrypi.local". (I do not know if this is supposed to work on Mac)

[etam]

The ethernet adapter isn't pi-branded, the power supply is.

[B.Goode]

The ethernet adapter isn't pi-branded, the power supply is.

My mis-interpretation: I got lost in the cross-referenced Q&A!

The question remains: is the external network adapter compatible with your Mac and is it correctly installed? Is it possible to test it by using it for your main internet connection?

[etam]

Well when I connect it to the mac the status of the connection says "connected".

[B.Goode]

I guess you are attempting this 'the hard way' because there is some reason why you cannot connect the RPi ethernet cable directly to the same network device as your Mac?

An RPi running Raspbian 'just works' when connected to a working Network outlet on a network that assigns valid IP addresses from its own dhcp server. That's how I work the majority of the time. Other than the requirement to enable the ssh server (a recent security feature added by the Raspberry Pi Foundation) there is no configuration needed on either the RPi or the network.

For that reason I conclude that your issues are related to the configuration of your Mac, and at risk of being thought guilty of buck-passing or finger-pointing I wonder if you would be better off asking about ICS configuration in a Mac-focussed forum?

[Ernst]

Well when I connect it to the mac the status of the connection says "connected".

A few hints:
- you must learn to use code tags
- you must learn to quote
- you must learn to give relevant information

You must try to move into our position and ask your self if the information you are giving will be enough for us to help you.
At the moment I do not have a clue what you are writing about.

[etam]

I guess you are attempting this 'the hard way' because there is some reason why you cannot connect the RPi ethernet cable directly to the same network device as your Mac?

I'm trying to run my pi through my laptop via ethernet so I don't have to use a monitor and buy a keyboard and mouse.

After doing some research it appears I have to do this through SSH but have to enable it on the pi somehow??
