telnet connection failed on port 23

0

i'm suppose to log into remote machines using telnet but in the task i have, there's no ip adresses for that ! instead i have hostnames. i'm a bit new in this and i don't know what i'm suppose to get. i'm asked to try these following: 

>telnet cs.purdue.edu
>telnet crete.dcs.gla.uk

i keep getting the same result:

Connecting To .......Could not open connection to the host, on 
port 23: Connect failed

i know the telnet command usually requires two arguments but it's not specified in this task! i tried to enable telnet on services but i didn't find it, i also restarted the pc after downloading the telnet client and even tried to run the command several times and in two different computers but still the same result ! is there any solutions or clarification for this problem ?

OS : win 10

If you have specific instructions for whatever this assignment is, it would help if you could edit your post and quote the instructions verbatim. It may become clearer to us what they're intending for you to do.

that's why i'm confused !! there's no much details ! at first they asked to try telnet with specifying the port then right away like this !! maybe the assignment is missing a part ! i'll check with the professor !! thank you – Mîrá Gìtä – 2018-11-10T01:10:31.210

Is it possible that you should be in a certain specific network for this to work? – Aulis Ronkainen – 2018-11-10T13:03:11.240

Port 23 is the usual telnet port. You can't connect to cs.purdue.edu because they don't allow it. I can't either.

 C:\WINDOWS\system32>telnet cs.purdue.edu
 Connecting To cs.purdue.edu...Could not open connection to the host, on port 23: Connect failed

There's nothing you and I can do to make purdue accept telnet connections.

Have you been specifically directed to use telnet to cs.purdue.edu?
