Galileo G2 - can not become root?

$

Hello,

I am getting started with the intel galileo g2 board. I ran the basic arduino sketches using the following link:Intel Software Academic Program  (Course : Intel Arduino IDE Hello World ( PPTX - PDF ))
I than tried running the basic on-board linux using the next PPTX from the same link (course : Networking ( PPTX - PDF ) ). Here i had the following problems:

I AM USING THE WINDOWS ON MY LAPTOP, NOT LINUX WHICH IS USED IN THE PPTX


1)

I was not able to connect to my board using SSH with IPv4 or IPv6. I tried with putty and them also with tera term. I am sure that the ip and mac was given to the board as it was also displayed on the serial monitor. I used the following arduino sketch and the output of serial monitor is attached in image 1.

 

void setup() {

}

 

void loop() {

system("telnetd -l /bin/sh");

system("ifconfig eth0 169.254.1.1 netmask 255.255.0.0 up");

system("ifconfig eth0 > /dev/ttyGS0");

delay(2000);

}

 

I was finally able to do it with telnet using ipv4 and port 23 on teraterm. I need to ask why ssh is not working for me?


2)
When i was finally able to connect, i could not become the root user as described in the networking PPTX on the above link. I see that i can enter the root directory but can't become root user. How can i do it? also what can i explore with this on board linux image? The image when i am logged in is attached as image 2.
