I've created an RSA keypair that I used for SSH, and it includes my email address. (At the end of the public key.)

I've now changed my email address.

Is it possible to change the email address on the key, or is it part of the key and I would have to make a new one?

The Openssh ssh and scp command provied an -i command line option to specify the path to the RSA/DSA key to be used for authentication.

Looking at the sftp man pages I was not able to find a way to specify the RSA/DSA key.

I am looking for a way to do initiate an sftp session that will use a specified RSA/DSA key, and not the ~/.ssh/id_{dsa,rsa} keys.

I tried OpenSSH sftp client on Linux...but it should have the same options on other platforms.

ssh sftp rsa dsa

My Git setup runs fine on Linux, but when I try to set things up under Windows (using Git for Windows and TortoiseGit), I don't know where to put my private SSH key (or, better still, how to tell ssh where it's located). I'm using the standard ssh.exe option during installation of Git for Windows. The setup runs fine if I allow password authentication (in lieu of RSA) on the server.

windows ssh rsa git private-key

I have a Linux server that whenever I connect it shows me the message that changed the SSH host key:

$ ssh root@host1 @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is 93:a2:1b:1c:5f:3e:68:47:bf:79:56:52:f0:ec:03:6b. Please contact your system administrator. Add correct host key in /home/emerson/.ssh/known_hosts to get rid of this message. Offending key in /home/emerson/.ssh/known_hosts:377

RSA host key for host1 has changed and you have requested strict checking. Host key verification failed.

It keeps me for a very few seconds logged in and then it closes the connection.

host1:~/.ssh # Read from remote host host1: Connection reset by peer Connection to host1 closed.

Does anyone know what's happening and what I could do to solve this problem?
