如何不出现如下提示？
ssh [email protected]
The authenticity of host '10.20.9.193 (10.20.9.193)' can't be established.
ECDSA key fingerprint is SHA256:WGRtppPJg6SAz6/JMkN8LAiy5uFPoBjvIW8h0NNIn/s.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '10.20.9.193' (ECDSA) to the list of known hosts.
[email protected]'s password: 我不想每次都有这个提示改如何设置？
执行策略
-
配置SSH客户端的全局配置文件：在本地机器上，找到SSH客户端的全局配置文件（通常位于/etc/ssh/ssh_config或/etc/ssh/config），并添加以下行：
StrictHostKeyChecking no UserKnownHostsFile /dev/null注意：这将禁用主机密钥的验证和记录，风险是可能无法检测到主机密钥的更改。
-
使用SSH命令行选项：每次使用SSH命令时，可以添加以下选项来跳过主机密钥验证：
ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null [email protected]这将在命令行中设置选项，以便在连接时跳过主机密钥验证。
修改配置
修改/etc/ssh/ssh_config如下：
# 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.
