Question

我正在尝试 ssh 进入如下设备：

ssh [email protected]

然后它要求输入密码，一旦我输入密码，它就会显示上次登录，然后光标开始在下一行中闪烁，而不会打开提示：

C:\Windows\system32>ssh [email protected]
[email protected]'s password:
Last login: Tue Sep  5 09:42:25 2023 from 169.254.52.134

我如何进一步了解该设备？我尝试使用 -vvv 然后它显示以下内容：

    rahulsharma@Rahuls-MacBook-Air ~ % ssh [email protected] -vvv

这是我的 ssh_config 文件：

#   $OpenBSD: ssh_config,v 1.35 2020/07/17 03:43:42 dtucker Exp $

# 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.

# This Include directive is not part of the default ssh_config shipped with
# OpenSSH. Options set in the included configuration files generally override
# those that follow.  The defaults only apply to options that have not been
# explicitly set.  Options that appear multiple times keep the first value set,
# unless they are a multivalue option such as IdentityFile.
Include /etc/ssh/ssh_config.d/*

# 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.
