@mitu said in Ssh help/background music:

Since background music is an add-on that's not part of RetroPie, the USB transfer method doesn't work. What's the error you get when you try the SSH connection with Putty ?

Ok when I use winscp the message I get is sftp connection unavailable but something about FTP being available.

Ive enabled ssh, so not sure why this would be?

Check if the SSH service is running, from the PI:

systemctl status ssh

You should get something like:

● ssh.service - OpenBSD Secure Shell server
   Loaded: loaded (/lib/systemd/system/ssh.service; enabled; vendor preset: enabled)
   Active: active (running) since Fri 2019-07-26 15:58:35 EEST; 3 weeks 2 days ago
 Main PID: 748 (sshd)
    Tasks: 1 (limit: 4915)
   CGroup: /system.slice/ssh.service
           └─748 /usr/sbin/sshd -D

If the status of the service is not 'enabled/running', then SSH is not working on the PI.

@mitu I've done this and I'm getting this message back

I'm guessing the bit underneath isn't what you'd expect to see?

Wish I knew what was causing this. If anyone can help it would be much appreciated

Are there any error messages from ssh in putty or from WinSCP?

You also could give us the output from ssh with the -v option. For example ssh -v pi@retropie or whatever username and hostname your Retropie is accessed by in the network. With -v, ssh gives much more information that may point in the right direction. If you want, you may anonymize the output to some extend, as long as it remains original enough for debugging.

@Clyde

This is the output of the file you mentioned. Any idea what this means?

@Clyde @mitu any help would be appreciated 👍

Try re-generating the sshd server keys - maybe the errors shown in the log have something to do with the connection not working - https://www.cyberciti.biz/faq/howto-regenerate-openssh-host-keys/.

It says that (some of) your ssh host keys on the Pi couldn't be read, which could be fixed by the method that @mitu linked to. Maybe that will solve your problem.

But I asked you for any messages on the system you're trying to connect to your Pi from by whatever means you tried to connect to your Pi with (WinSCP, ssh in putty, etc.).

I was getting a message saying sftp unavailable, but FTP is available.

I've done the above and I'm now getting a message saying network error....

Jste84

@mitu I've tried but I'm.now getting a network error. Software caused connection abort message.

Clyde

@Jste84 Please give us the exact error messages, as we can't deduce much from a summary like "a network error".

mitu

@Jste84 Most likely the procedure didn't fix - can you run systemctl status ssh again and see if any errors are shown, from the log ?

@Clyde @mitu I've just tried to reinstall putty, to check if this makes any difference...but no joy. Slightly different error message

Are you sure ssh is running? How did you run raspi-config before? you should use it again and make sure the ssh service is running on boot.

also you can do
tail /var/log/auth.log
or just nano to it and look at the last lines to see why it kicked you off. If it is running, that is.

mitu

Putty is a simple program, doesn't need to be re-installed. The errors in the ssh service indicate that sshd doesn't work correctly, hence the Putty error. If you run - from a command line on the Pi - ssh localhost, you'll probably also receive an error.

I've run the procedure to reset the SSHD host keys and they are re-generated - make sure you've correctly executed the steps on that page and that you restart the ssh service.

@mitu maybe im doing it wrong. When I'm following the guide and get to the step keygen and it says remote server name here.... What should I be putting in?
