I know that Linux may, depending on configuration, allow the interactive user to reboot the server by pressing Ctrl-Alt-Del even without logging in. I have a remote console session over SSH to a remote server that I cannot log into, but I want to reboot it. Is it possible to somehow send the key combination Control-Alt-Delete over SSH (or telnet)? If so, how?
Edit: to clarify, I am not just connected to the server's SSHD over SSH - I am connected via a KVM over IP switch, so it's a serial console. But this connection itself is over SSH and my question is how to send the Ctrl-Alt-Del key combination over it.
