I got my computer for my turtlebot today, and I think (and hope!) I got it set up properly. However, while I was going through the tutorials, I encountered a problem with ssh-ing into my turtlebot. I typed "ssh turtlebot@turtlebot" into my terminal, but it says "ssh: Could not resolve hostname turtlebot: Name or service not known". Is there something I need to know about how to ssh into something? Do I need to type something else into the terminal?

The computer that you're SSHing from needs to know what IP 'turtlebot' refers to is. Try finding the IP of the TurtleBot by running ifconfig in a terminal on the TurtleBot. Then, try:

ssh turtlebot@<IP>

If you are setting up a computer from scratch and are not using the official TurtleBot iso, you may also need to install a server for ssh on your TurtleBot:

sudo apt-get install openssh-server

I was using the official iso, but I did not have an ssh server on the computer. So I may have not downloaded it properly. Can I re load it from the same USB stick?

Easiest thing to do would be to run the second line from above to install it - it'll be much faster. I had thought the official distribution had the server installed, but it's possible that it's not included by default.

I don't believe it's in the ISO at the moment. TIcketed

I just checked it is in the ISO.

First of all check the ip-addresses of your systems.

You can do this with the command "ifconfig" at the terminal. With this information, you can reach the remote system very easily.

ssh user@remote-ip-address

You are using your own IP adress as a target ( You cant be the source and the target at the same time ! The idea of ssh is to log in from an other computer on the network. It should see turtlebot as a local IP, ideally something like 192.168.1.xx

Alright. I installed the ssh server, but it still can not ssh into my robot.

I type "ssh turtlebot@"

And get back "ssh: connect to host port 22: Connection refused"

What do you think is the problem?

That's the "local IP" of the laptop. You can only use that IP address if you're physically on the laptop. If you're on a wireless network, type "ifconfig wlan0" to get the proper address

Type $ifconfig on your turtlebot's terminal.

Near the wlan0 section you will see your turtlebot's inet

Thats the correct address
