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/.

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

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.

Jste84

@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?

mitu

@Jste84 The keygen step is the execution of

sudo dpkg-reconfigure openssh-server

Are you executing that on the PI ?

Jste84

@mitu yes executed that on the pi. Was looking at step 3? Do I need to do that? And if so do I do it on the pi?

I

mitu

Step 3 is not necessary - that's just for the SSH clients which connected before to the same machine.

@mitu If he needs only a possibilty to copy some files then why not set port to 21 and use FTP? This should work out of the box.

FTP is a different protocol, you'd need a FTP server, while SSHD only provides sftp/scp.

Ssh should be running. I've enabled it via raspiconfig. Tried this via both the retropie settings and manually by quitting emulation station

Jste84

@mitu ahh ok that's what I thought. Then yes, step 1 and 2 are complete. I keep getting remote side unexpectedly closed network connection message from putty

Jste84

Still getting the same error when I enter systemctl status ssh
