When using telnet by using the command:
telnet <host ip> <port>
I can connect but then I cannot see what I am typing.
So I try:
telnet
set localecho
open <host ip> <port>
But this time it just hangs with the message:
Connecting to <host ip>...
How can I use telnet successfully after setting localecho?
It actually isn't hanging; it's just that, for some reason, it doesn't give any feedback to show that it's connected. If you start typing, you'll see that your input shows up in the upper-left hand corner of the window, overwriting what's already there. For example:
GET / HTTP/1.1rosoft Telnet Client Escape Character is 'CTRL+]' Microsoft Telnet> open example.com 80 Connecting To example.com...
You can see that I've typed GET / HTTP/1.1, overwriting Welcome to Mic.
(By the way, notice that I didn't have to type set localecho: for me local-echo was already on when I launched telnet without arguments, and I'm betting that for you it's the same.)
