Connection closed by foreign host...

Hi All,

I'm following along with the tutorial, but I'm not getting any response from the httpbin.org server. I'm connecting just fine, but both my local terminal and the console in workspaces are returning "Connection closed by foreign host.". I can connect to the site through a browser. Any ideas most welcome!

$ telnet httpbin.org 80 Trying 54.175.219.8... Connected to httpbin.org. Escape character is '^]'. GET /xml HTTP/1.1 Host: httpbin.org Connection closed by foreign host.

After a failed attempt I reset the console(work space) and completed the first action as mentioned, I then pasted the text below into the console and pressed return twice. Yah me! It worked. & Thanks Jason Anders.

GET / HTTP/1.1 Host: httpbin.org

Hey Simon, I encountered the same problem, and I found after typing 

GET / HTTP/1.1
Host: httpbin.org

You should press enter twice, I guess that telnet is waiting for you to give the rest of the request. BTW:Christ has been talking so fast :D .

How do you type the second line without pressing enter, how do you get down ????

Hey Simon,

The "connection closed by foreign host" will come up ~60 seconds after you open the connection if there is no action. This is normal and done by httpbin.org. I found it best to watch what Chris does completely then pause / rewind and follow along (with your new connection). If you don't, sometimes he explains what he is doing for longer than 60 seconds, and then you will lose the connection just as he types the commands.

Hope this helps. :dizzy:

Thanks Jason. Sadly, I've been doing exactly that! Thanks for the advice. :)

Simon, did you go to a new line by pressing enter after typing HTTP/1.1?

I never figured out how to go to a new line in the workspace console. edit: Nevermind, it's option + enter on mac (probably alt + enter for windows)
