"ssh localhost" returns "connection closed by ::1" under Cygwin
installation on windows 8
Hi,
I tried to install Hadoop on windows 8 to form multi-node clusters. So first I have to install Cygwin in order to make SSH working. I installed Cygwin with Sshd service successfully. And also I generated passwordless keys. But when I run "ssh localhost", it returns "connection closed by ::1". Does anyone has the same experience? How did you solve it.
Thanks!
Yepeng

no special reason, how to use ipv4 instead? Thanks!
For the issue I met, I will try the following link:

Hi,
Is there a reason why you are using ipv6?

This May help you
I experienced this same issue. The problem for me at least, was the
creation of the cyg_server user using the ssh-host-config. It was created
without a home directory and with it's shell set to /bin/false. So, I
altered the /etc/passwd file for the cyg_server user to reflect
/home/cyg_server (changed from /var/empty) and /bin/false to /bin/bash and
created the home directory for the user. Tried to reconnect using the
cyg_server user and voila.
in short: mkdir /home/cyg_server vim /etc/passwd cyg_server:...(bunch of
stuff)...:/var/empty:/bin/false to cyg_server:...(bunch of
stuff)...:/home/cyg_server:/bin/bash
Presumably cygwin has a usermod command or synonym that would do this a
little safer. But I was impatient and this is what I did. If anyone follows
this please note to be extremely careful when editing the /etc/passwd file.
