连接在cygwin中由:: 1错误关闭

Question

我正在尝试使用cygwin进行ssh连接.我遵循了这里给出的指示.当我发出ssh localhost命令时,我得到Connection closed by ::1错误.因为我是unix和cygwin的新手,我无法弄清楚出了什么问题.请任何人都可以告诉我为什么会出现这个错误以及如何解决它？

我的cygwin shell看起来如下:

$ 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:

我遇到过同样的问题.至少对我来说问题是使用ssh-host-config创建cyg_server用户.它是在没有主目录的情况下创建的,并且它的shell设置为/ bin/false.因此,我更改了cyg_server用户的/ etc/passwd文件,以反映/ home/cyg_server(从/ var/empty更改)和/ bin/false到/ bin/bash并为用户创建主目录.试图使用cyg_server用户和voila重新连接.

简而言之:

mkdir /home/cyg_server
vim /etc/passwd
cyg_server:...(bunch of stuff)...:/var/empty:/bin/false

至

cyg_server:...(bunch of stuff)...:/home/cyg_server:/bin/bash

据推测,cygwin有一个usermod命令或同义词,可以做得更安全一些.但我很不耐烦,这就是我所做的.如果有人这样做,请注意在编辑/ etc/passwd文件时要特别小心.
