不能ssh到localhost，感觉我已经尝试了stackoverflow上的所有内容。我一直在玩ssh_config试图解决我的问题，但我仍然得到“远程主机关闭连接”或类似“可以继续的身份验证：publickey。调试1：没有更多的身份验证方法可以尝试”取决于我的设置
以下是我目前看到的内容：
$ ssh -v localhost

我当前设置的etc / ssh / ssh_config是：
This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.
# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.
# Site-wide defaults for some commonly used options. For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

我的密钥似乎在sshing时工作但挂起在debug1行：接收到SSH2_MSG_SERVICE_ACCEPT
如果在尝试ssh之前取消设置$ SSH_AUTH_SOCK，一切都按预期工作
答案 0 :(得分：0)
应该有一个名为＆＃34; authorized_keys＆＃34;的文件。您应该将一个自己的公钥（证书文件）添加（复制粘贴内容）到其中。

帮助他人：有多个ssh配置文件！我必须经过我的ssh配置一百万次，但我一直在查看错误的文件。我的sshd_config中有错误。因为我正在使用我自己的机器，所以这两个文件都必须正确设置。 （一个用于客户端的文件，一个用于服务器配置的文件 - ＆gt;至少这是我目前的理解）。 cat /var/log/system.log | grep ssh指出错误发生在另一个文件中。仍然在ssh上挂着我，但至少还有一步：）
