Hi there.
Do you ever get the irrepressible urge to reach out and connect?
Well, if the connections you're after involve servers,
remote computers, or stripped-down development devices,
then the odds are pretty good that there's going to be an SSH or
Telnet session coming soon into your busy social life.
But what do you do when things don't work out?
What's the plan when your request is refused,
if the host doesn't respond, or if your session suddenly times out?
When should you be using Telnet, a protocol that,
after all, is nearly 50 years old, and when should you not?
The SSH and Telnet networking protocols are mature and absolutely
reliable tools for handling remote connectivity,
but understanding how they're built and what kind of care and feeding they'll
need to keep them happy involves a bit of a learning curve.
In this course,
I'll introduce you to the basic design and function of the two protocols
and present some common problems and their solutions,
along with some helpful troubleshooting techniques.
If you've got a basic knowledge of TCP/IP and a couple of virtual or
physical machines to play with and you want to learn how to dig yourself
out when your remote connections go wrong, then this is a course worth taking.
