No, they do not have support for z/VM. There is an inherent architectural problem with an ssh *server* on VM: The IP connection does not terminate in your virtual machine. When you login to a system with ssh, you are expected to have logged into your own account (a la telnet), not have a proxy login (a la ftp). Your profile runs, your disks are set up. An scp command would have as its local context, all the files you have accessed (or have access to) in your virtual machine. If ssh were just an alternate way to transfer files, that wouldn't be a big deal since the ftp server has to deal with the same issues. But it isn't. It's a network connection has an endpoint in your virtual machine that scp, sftp, other ssh services (e.g. interactive console/keyboard) can use. In previous discussions here, there was a feeling that an ssh *client* in CMS was more important than having the ability to ssh *into* the system. The client is technically doable, and I await the day that z/OS has one that is not dependent on openSSH. Alan Altmark z/VM Development IBM Endicott
