I am newbie in Linux System Administration. I need help in one of the issue I have to resolve. My company is using SFTP server (using open ssh 4.3). They want to jail root the users in their home directories. So I suggested them to upgrade to open ssh 5.2 which supports jail rooting of servers.
But I want to know if we upgrade the open ssh version, the certificates they are using are going to change?? Because they dont want to change the certificates and keys, I need to search for another solution. Please guide me in this regard.
