I am using authorized_key instead of userId password to send files to my FTP server using sftp. The sftp server now has my id_rsa.pub in the authorized_key. I now have 10 more servers which want to send files to FTP files using sftp. I know that I can generate key pairs for each one and add the 10 id_rsa.pub to authorized_key file of the FTP server. But I need to ask the person who manage the FTP server to do the copy.
This is just a test environment. Will just copy the keypair from my first server to each of the 10 new servers work ? The only thing I see in the id_rsa.pub that seems to be server specific is 'user@server'. But google search says that it is only a comment and will not be used.
