    Connect Galileo to mac via ethernet


      Hey guys, all the examples I can find for connecting to the Galileo directly through ethernet to the computer involve using a PC. I am trying to access the galileo terminal on a mac via ethernet from the Galileo to a thunderbolt port on my mac. I have uploaded the sketch (attached) to the board in order to start the ethernet, however I am unsure of what to do after this. Could anyone provide me with some assistance? Sorry, I'm still a bit new to networking.

          con't find your sketch attachment. Anyways, what do you try to achieve? If you want to access and work with the native Linux on Galileo I would suggest to connect via ssh to the system.

          If you use e.g. the Yocto* SD card image from https://software.intel.com/en-us/iot you already have a ssh daemon running on the target.

            I have the Yocto 1.6 image on the sd card already. When I connect the ethernet to my mac, I'm assuming I leave it as DHCP? The arduino sketch that i uploaded was:


            #include <SPI.h>

            #include <Ethernet.h>


            // the media access control (ethernet hardware) address for the Galileo:

            byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; 

            //the IP address for the Galileo:

            byte ip[] = { 192, 168, 0, 2 };   


            void setup()



                Serial.println("Attempting to start Ethernet");

                if (Ethernet.begin(mac) == 0) {

                    Serial.println("Failed to configure Ethernet using DHCP");

                    Serial.println("Attempting to configure Ethernet using Static IP");

                    Ethernet.begin(mac, ip);


                Serial.print("Your IP address: ");




            void loop () {}


            If I want to ssh to the Galileo, I bring up terminal and type ssh root@<ip address> but what is the ip address of the board?

              if you plug the system to a DHCP server it will automatically get an IP address.

              In order to ssh into the board you can use:

              • IPv6: you can compute the IPv6 address via the MAC address of your board printed on the eth sticker - there are online MAC -> IPv6 calculators available
              • if your MAC supports avahi (bonjour) which I guess it does you can connect via the avahi name quark<MAC{7..12}>, where <MAC{7..12}> means the last 6 digits of the MAC address printed on the eth plug. e.g. ssh root@quark123456 if the MAC address ends with *123456
              • using a simple Arduino sketch to print the IP address as shown elsewhere in this forum; something like
                delay(2000); // give some time to open up the serial console [CTRL+SHIFT+M] from within Arduino IDE
                system("ip a > /dev/ttyGS0"); // prints all network information including the IP address of
                alternatively something like:
                system("ip a | grep -A 3 "enp.*:" | grep inet"); // print only ipv4 and ipv6 information
