HAVING AN WEIRD ISSUE HERE !!!

1st things 1st. I'm running windows 10 pro. Telnet is enabled here. I've checked it and it was enabled by default. I've tried the same thing in both cmd & Powershell, but the same things happen:

  1. I write this and hit enter: telnet httpbin.org 80
  2. The screen goes blank.
  3. before going blank says connecting to httpbin.org ( for a few sec before going blank).
  4. Accepts no input after that.
  5. dead silence.
  6. fear crawls into my heart.
  7. then I kill the program
  8. write about it here.
  9. then I wait
  10. And keep waiting

Hey there, Tricia Roberts, as you can see, I asked this question a few months ago, and since it has not been answered, I forgot about it completely. Now that you've asked me, I remember I still couldn't figure it out. So, I did a quick research but with no luck.

I think that httpbin.org is not working properly. In fact, I've tried other links and some of them work, some of them don't, I don't know the reason though.

As far as we are concerned, telnet is not efficient in establishing connections anymore. It has got 0 encryption enabled, which means every bit of information transferred is in plain text, everything you send over this connection is open to everyone, so people don't use it anymore. Telnet is there just for demonstration purposes ( at least that's how I've seen people using it).

However, a demonstration is not the only thing it can do, people made fun things with it. Here's a command you can type in the cmd:

telnet towel.blinkenlights.nl

enjoy.

And since I answered my own question, I guess I can mark it as the best one ( maybe for now ). :smile:

Thank you.

Nafis, I got the same issue you explained. Our command got submitted but we entered a black hole which I couldn't exit out of unless I quit the command window. The command line is a scary, dark place.

I have the same problem and perhaps I have found some solution. There is bug in version 8.2.3.

But I don't know how to install newer version of telnet on windows 11
