Hello,
My SSH connection doesn't work any more.
I have two Computers A and B, which are in the same home-network.
This morning a was still able to connect by SSH from A to B.
I did some general configuration on B so I might have messed up something,
but I have no clue what it could be, as, as far as I can remember only accessed the /usr/share folder.
Then I switched B off and worked on A. After some hours I restarted B again, but couldn't connect any more from A to B.
On A:
Code:
$ ssh myname@B
ssh: connect to host B port 22: Connection refused.
but on B:
works.
After some testing I rebooted both A and B, without any result.
Also disabling the firewall on both A and B didn't change anything.
Pinging from A to B and vice-versa works.
On A:
works.
But on B:
Code:
$ ssh localhost
ssh: connect to host localhost port 22: Connection timed out
On A:
Code:
$ netstat -lnptu

It seems that B isn't listening on port 22.
I hope I provided enough informations, I would be happy for any help!
