SSH Connection refused

[gastonkilo]

Hi all,

I'm the happy owner of a raspberry pi with raspbmc on it for a year know and so far so good...
Lately I wanted to copy some files so I ssh like I used to do from my Mac terminal using

Code: Select all

ssh pi@192.168.0.XX

with the correct IP (IP is fixed on my dhcp router).
Surprisingly enough, I got a connection refused on port 22 !

My constraints :
I have no keyboard / mouse attached to my pi.
I have only a laptop to connect to it.
I have raspbmc (13.2 stable) install on it.
I cannot read the sd card (although I've try with a software that should enable my mac to read ext3 partition)

I can use the raspbmc extension to check the settings.
It says that ssh is on and firewall is off.
My mac firewall is off.
I can connect to my raspberry web interface with my browser as well as software runinng on it that have a web interface...

I know you cannot give me the magic answer, I'm more looking for ideas to troubleshoot...

Thanks a lot to anyone who take the time for me.
Much appreciated
Ben

Are you using keys or passwords to log in? Maybe your key was deleted, are you logging into the right account? Maybe root login has been disabled.

[gastonkilo]

I'm using the pi user with password.
So I assume it has not been deleted, also all my software (transmission, sickbeard, etc...) are running with it and they run fine.
Just in case, on my mac, I've deleted my known hosts but it doesn't even asks me to add the key it just refuse...

And you can successfully ping your raspi?

A while ago there was a problem with ssh on Raspbmc being restricted to ipv6. I'm not sure if that was automatically changed / solved in later updates.
Can you can check the contents of '/etc/xinetd.d/ssh'. Could be problematic without keyboard or ssh access...

[gastonkilo]

I'm not on IPV6 on my local network.
But I can try checking the file using XBMC gui.

Hi,
I would suggest 2 problems :

1) Is sshd started?
service ssh start

2) If it doesnt work, could you post the output of :
ssh -vvv pi@192.168...

[RaTTuS]

so you have xbmc on the raspberry - I dont think that uses the user pi

[DirkS]

You're wrong
Raspbmc does use 'pi'

[Nolaan]

I just thought about a 3rd way
if you have nmap installed on your mac can you do an : nmap -sn 192.168.0.0/24

You should be able to see all devices actually having a IP address assigned. If you don't see "Raspberry Pi" it simply means that it's not connected to the network.

[gastonkilo]

Thanks !
But it is connected has it download file to the internet and I can connect to it on port 80 through web browser

Please read the OPs first post. The Pi is connected and working. He just cannot connect with SSH...

I can try with xbmc gui.

I cannot do a service ssh start without keyboard and without... ssh

For the second thanks, i'll try as soon as I'm back home

Yeah yeah, it's just to be sure that we're talking the same language...

Then you could nmap --open 192.168.0.X , with the rpi address. If the port is closed, then I would recommend you to find a way to read its SD card.

[gastonkilo]

Ok thanks I'm going to do that !

Hi,

Result of the nmap :

Any lead ?

[Jeremy Davis]

SSH uses port 22 so your nmap results suggest that perhaps SSH server not running...

[gastonkilo]

Yep. But when looking at my settings using xbmc setting add-on it's says it's on...


Thanks a lot

[B.Goode]

If the GUI on the host says the service is running but an nmap scan does not find it then I would suspect one of the following possibilities:

. you have scanned the wrong host (Have you checked the network mac address associated with that IP address?)

. the service on the RPi has become hung/wedged/confused (Have you tried rebooting the RPi?)

I admit I have never run or scanned an RPi running xbmc software, so can anyone who has confirm that the list of open ports is what would normally be seen?

Yes, my raspbmc shows some of the same ports open (zeus-admin for example).

I see that vnc port (5900) is open. Have you tried using that for logging into your Pi?

Gr.
Dirk.

[gastonkilo]

It's logging me to the xbmc GUI which I can already access so not helpful

Thanks

[DirkS]

Well... I would say it's time to plug in a USB keyboard.

[gastonkilo]

Yes, I'll see if I can borrow one at work or something...

Do you a key that can prevent xbmc to load at startup by any chance ?
