I've been thinking about this for a while now...
I need to establish an automated connection between two machines. What's the
best way of doing this over a serial line? (PPP/SLIP/etc?)
The client machine should also be able to execute commands on the server
(run shell scripts). Is there a way to secure this connection (secure
shell?), and how to do it? If someone walks up to the machine, unplugs the
client, and plugs in another machine, access should be rejected.
Can you, for example, setup a ssh connection between the machines, with the
private key on the client machine hidden from everyone except root (no-one
will have root access). This connection has to be automated every time the
client starts. If the server dies and starts again, it should also try and
establish this connection (this can be done via a shell script running every
x minutes to check connection). The remote commands should also be automated
Is this at all possible? Should be, I think. I'll do the research, just need
some comments and (if possible) pointers.
