On Linux/Unix machine:
The command to generate an ssh key file is "ssh-keygen". Used without any parameters it will usually generate an SSH2 version RSA key. Additional options are available. See "man ssh-keygen (FreeBSD version)" for more details. (Most BSD and Linux distributions use OpenSSH or derivatives)
On a Windows computer you will probably be using either PuTTY or BitviseSSH clients, and they each have their own way to generate a set of public and private key. You may need to take an extra step to export the private key in OpenSSH format.
For example, with PuttyGen, after you have created your key, choose the "Conversions" menu and select Export OpenSSH Key (Force New Format) - this is the key you will use in iQSonar.
...
If the username is iQSonar, then the hidden folder .ssh will be located in /home/iQSonar/.ssh typically on Linux/Unix hosts.
