Forgive me for this simple ( and to some, stupid) question. Why is reaching the console ports of devices attached to a terminal server called Reverse Telnet. I am confused about the "Reverse" part.
1. You reach "terminal server" by some suiteable means (telnet, ssh, console) from a device say your computer.
c:\> telnet 10.10.10.1
2. You effectivily telnet to localhost (terminal server) on a specific port bound to certain TTY connection
termsrv > R1 ! ip host R1 2001 <<loopback_address_termsrv>>
Whats different for this second telnet is, instead of the telnet server (running on terminal server) presenting you with a second command shell it connects the mapped console port to the new telnet session. Effectively you read from or write to console port of R1.
R1 is oblivious about this whole operation. What's so "Reverse" about this second telnet session ?
