RE: process to generate a new RSA Connection key.

Hi Gerald,

When I have a need of using multiple keys for a user ( that seems to happen over time quite frequently ) I normally create a streamfile named config in the user's .ssh directory. Use CCSID 819.
Be careful to only give the user *rw authority to the file, otherwise issues might occur.
In the file you can put entries like:

Host host1
Hostname sftp.filetransfer.company.com
Identityfile ~/.ssh/nameofprivatekey
User remoteuser

Host host2
Hostname 123.123.123.123
Port 33333
Identityfile ~/.ssh/nameofanotherprivatekey
User remoteuser2

And so on........

Your commandline will then be as easy as

sftp host1

Also notice Jacks remark about naming the key-files when you execute the ssh-keygen command.
But it's a good safety routine to backup/rename current key-pair before creating a new pair.

Best regards

Stefan
