如何在同一台机器上从 Windows SSH 到 WSL

Question

长期读者，第一次提问。

我按照此答案中的说明进行操作：

如何通过 SSH 连接到“Windows 10 上的 Ubuntu 上的 Bash”？

我正在尝试在同一台机器上的 Windows 中从 PuTTY 进行 SSH。使用与我的配置文件匹配的端口 22。尝试了 127.0.0.1 和 127.0.1.1。但是，我仍然收到“拒绝访问”的消息：

最终我希望建立一个 Visual Studio 远程构建，但到目前为止我根本无法远程进入。我应该采取哪些后续步骤？

Process Hacker 为端口 22 显示了这一点（不确定这意味着什么）：

以下是 /etc/ssh/sshd_config 的内容：

# Package generated configuration file
# See the sshd_config(5) manpage for details

# What ports, IPs and protocols we listen for
Port 22
# Use these options to restrict which interfaces/protocols sshd will bind to
#ListenAddress ::
#ListenAddress 0.0.0.0
Protocol 2
# HostKeys for protocol version 2
HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key
HostKey /etc/ssh/ssh_host_ecdsa_key
HostKey /etc/ssh/ssh_host_ed25519_key

# Logging

# Authentication:

PermitRootLogin no
AllowUsers basel
StrictModes yes

RSAAuthentication yes
PubkeyAuthentication yes
#AuthorizedKeysFile     %h/.ssh/authorized_keys

# Don't read the user's ~/.rhosts and ~/.shosts files

# For this to work you will also need host keys in /etc/ssh_known_hosts
RhostsRSAAuthentication no
# similar for protocol version 2
HostbasedAuthentication no
# Uncomment if you don't trust ~/.ssh/known_hosts for RhostsRSAAuthentication
#IgnoreUserKnownHosts yes

# To enable empty passwords, change to yes (NOT RECOMMENDED)
PermitEmptyPasswords no

# Change to yes to enable challenge-response passwords (beware issues with
# some PAM modules and threads)
ChallengeResponseAuthentication no

# Change to no to disable tunnelled clear text passwords
PasswordAuthentication yes

Subsystem sftp /usr/lib/openssh/sftp-server

# Set this to 'yes' to enable PAM authentication, account processing,
# and session processing. If this is enabled, PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication.  Depending on your PAM configuration,
# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
UsePAM yes

把文件里的22端口改成其他的，比如2222，/etc/ssh/sshd_config然后用sudo service ssh --full-restartcommond重启ssh服务，就可以登录成功了，不知道是什么原因。

我也尝试将其用作 VisualGDB 的 Visual Studio 的远程 gdb 服务器，但效果不佳。VisualGDB 将在下个版本支持，如官网所示。链接为https://sysprogs.com/w/forums/topic/visualgdb-with-windows-10-anniversary-update-linux-support/#post- 9274

Answer 2

端口 22 不起作用，因为 Windows 带有内置的 SSH 服务器。

Windows 10 带有一个 SSH 服务器，它要么需要被禁用，要么需要更改用于 WSL 上的 SSH 的端口。我选择了后者，并为 WSL SSH 使用端口 2200。
