Hi,

I have setup my home pc as ssh server. The router is set to forward the port 5022 to 22 in my home pc.
I used to connect my home pc from office to update the files using rsync. I use key based ssh connection to avoid prompting for password.

Recently, I get the error as
ssh: connect to host myhomepc.no-ip.org port 5022: Connection refused

The strange thing is that, I was able to connect to home pc from another pc in my office. I somehow got kicked off by my own pc []

Then, I deleted the .ssh directory in my home pc and tried again. It worked for the first time I connected. But, when I tried rsync next time, it didnt respond, and I am back to square one.

I didnot enable the firewall. The security setting is standard... I dont know what I am missing...

It would be great if anyone can help me figure this out.

What sounds like it happening is the identification key for your machine is changing. I don't think there's anything wrong with your home PC, but you'll need to figure out why your other machine keeps regenerating it's RSA key.

One thing to check is the permissions on the private key. Make sure you are the only one who can read the file.
