ssh가 debug1에서 멈췄습니다: client_input_channel_req: 채널 0 rtype [이메일 보호됨] 응답 1

다음과 같은 장치에 SSH로 접속하려고 합니다.

ssh [email protected]

그런 다음 비밀번호를 묻고 비밀번호를 입력하면 마지막 로그인이 표시되고 프롬프트가 열리지 않고 다음 줄에서 커서가 깜박이기 시작합니다.

C:\Windows\system32>ssh [email protected]

이 장치에 대해 자세히 알아보려면 어떻게 해야 합니까? -vvv를 사용해 보았더니 다음과 같이 표시됩니다.

#   $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.
