I got my RPi a few days ago and I feel rather useless. This is for the very simple reason that I have yet to even be able to ssh into my pi. In other words, I have not logged into it, and I have not accessed it. I am trying to remotely connect to my Pi through my wireless laptop with an RJ-45 Ethernet Cable. I'm currently running Ubuntu 14.04 LTS and my pi is using Raspbian. The SD card I'm using is 8 GB. Whenever I attempt to ping it using nmap, it doesn't show up. (Also, I'm using a Model B Pi.) Any help would be appreciated., thanks. -Omega Emrys

PS: I know what the search bar is, don't tell me to use it please.

I finally found my pi's ip, except I'm not sure it's the right ip. Here is my ifconfig:

When I disconnect the Ethernet cable, the inet address at the very top disappears. However, when I try to nmap -sn the ip, it doesn't refer to the host as raspberry pi. Also, I do manage to ssh into it but when it ask me for the password and I enter "raspberry", it denies me permission, any help you could give me would be wonderful. Thank you very much, Omega.

(EDIT: It just changed the inet address to 10.42.0.1 after I unplugged and plugged the Ethernet a couple of times, which I'm guessing suggest that it is dhcp?)

(EDIT: I did as was suggested by Wilf, and this is what I got:

  • How did you installed your pi ? Did you follow a guide such as this one ? – superbob Jul 17 '14 at 14:45
  • I was going to ask if you'd turned on ssh - but your penultimate paragraph sounds like it. Are you running ssh pi@10.42.0.1 (or whatever the ip is now...) – Daniel Jul 17 '14 at 14:52
  • @Daniel I am, but when it asks for the password, I enter raspberry and it denies me the access. – Omega Emrys Jul 17 '14 at 14:58
  • Precisely, what text does it print asking for the password? – joan Jul 17 '14 at 17:04
  • @joan $ ssh pi@10.42.0.1 ---> pi@10.42.0.1's password: – Omega Emrys Jul 17 '14 at 20:09
  • if you run nmap -O IPADDRESS (might be the -A option instead of -0, can never remember), do you get anything referencing to the 'Raspberry Pi Foundation'? You can also check a range of IP addresses - e.g. nmap -O 192.168.1.1-20. – Wilf Jul 20 '14 at 11:05
  • If the nmap output is from the Ubuntu machine, it looks like it could of been scanning itself... What you should see is a entry about a MAC address, like MAC Address: B8:27:EB:0F:E7:65 (Raspberry Pi Foundation). If all the IP addresses on your network have the same prefixes (e.g. 192.168.1.) , you should be able to check multiple ones using nmap -O 192.168.1.1-20, where the last entry specifies the range to check. This also depends on whether the Pi is connected to the internet correctly at all - are the ethernet lights lit up? – Wilf Jul 20 '14 at 15:33

  • @Wilf, check my edit for more details on the lights. I am connected to my device through "Wired Connection 2" – Omega Emrys Jul 31 '14 at 16:44

How I did a headless setup on a Mac.

  1. Downloaded etcher.

  2. Downloaded zip file of raspbian (you are using Ubuntu, not sure if it will work this way)

  3. Plugged in my SD card and burned the zip file to the SD card with etcher.

  4. Add a empty file called ssh, make sure there is no extension such as .txt

  5. Insert SD card into pi, connect Ethernet cable and micro USB cable.

  6. power up the pi, and find your pis IP address on your router page.

  7. Open terminal and type: ssh pi@YourIpaddress

  8. Change YourIpaddress in the last step to your raspberry pis up address

  9. Your done!

Hope this helps :)

Try this:

  1. Do a fresh install with a latest image of Raspbian OS using Etcher.

  2. Go to Raspberry Pi Configuration and enable SSH in Interfaces tab.

  3. Reboot the Pi.

  4. Connect the Pi and the computer/laptop to use in remote in the same network.

  5. Check your ip via executing ifconfig in terminal.

  6. If your using Ubuntu/Manjaro?Linux Mint, open terminal and execute ssh pi@xxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx is the ip of the pi.
