Connection closed by ::1 error in cygwin


I am trying to do ssh connection using cygwin. I have followed instructions given here. When I fire ssh localhost command I get Connection closed by ::1 error. As I am newbie to unix and cygwin, I am not able to figure out what has gone wrong. Please can anyone tell me why this error comes and how to resolve it?

My cygwin shell looks as follows :

$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/Shekhar/.ssh/id_rsa):
/home/Shekhar/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/Shekhar/.ssh/id_rsa.
Your public key has been saved in /home/Shekhar/.ssh/id_rsa.pub.
The key fingerprint is:
85:69:77:cc:fd:21:8a:ce:fe:46:41:ee:c8:e7:3d:7b Shekhar@Shekhar-PC
The key's randomart image is:
+--[ RSA 2048]----+

Solution

  • My problem is solved. I just removed cygwin and re-installed it and somehow its working properly now.
