unix server

We have a few netapp and other Unix server running here. An NFS server is configured on both netapp and Unix. How do I see all exported file systems from netapp and unix server using Linux command line option?

I‘ve a remote Unix server running with OpenSSH remote login service. The openssh is configured for passwordless login using ssh keys. Our ISP allows to boot all Linux servers into the rescue mode. It allow us to bring a server online remotely in order to troubleshoot system problems that would normally only be resolved by an OS Reload (such as accidentally deleting files or wrong firewall configurations blocking ssh access). When server boots into a remote rescue mode I can connect using SSH. They SSH keys will not be the same in the rescue mode so I get key mismatch messages as SSH keys are re-generated on each boot:

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
e1:9b:5c:16:a6:cd:11:10:3a:cd:1b:a2:16:cd:e5:1c.
Please contact your system administrator.
Add correct host key in /home/user/.ssh/known_hosts to get rid of this message.

How do I ignore OpenSSH hos key checking from my Apple OS X laptop while login using the ssh?

How do I enable console redirection under OpenBSD so that I can see my remote server boot information and any diagnostic information that is normally printed to the screen? I’ve already enabled serial ports in my server BIOS and wired them up. How do I configure and access OpenBSD UNIX x86/amd64 server over serial console?
