sshd_config 文件是 OpenSSH 服务器的配置文件,用于定义 SSH 服务器的各种参数和行为。通过编辑这个文件,管理员可以调整 SSH 服务器的安全设置、认证方式、日志记录等。 2. HostKeyAlgorithms配置项在sshd_config中的意义 HostKeyAlgorithms 配置项用于指定 SSH 服务器在认证过程中可以使用的公钥算法。这些算法用于生成...

ansible_ssh_extra_args should do it too, although in my testing, it did not seem to work. In ssh client configuration Add the following at the top of ~/.ssh/config : Host 127.0.0.1 HostKeyAlgorithms +ssh-rsa PubkeyAcceptedAlgorithms +ssh-rsa Fixes...
解决办法是 ssh 命令指定算法: ssh -o HostKeyAlgorithms=+ssh-rsa -o PubkeyAcceptedKeyTypes=+ssh-rsa user@host -p 2222 上面比较麻烦,可以修改 ssh 配置文件 ~/.ssh/config,对于无法成功连接的 host,增加以下配置项: HostKeyAlgorithms +ssh-rsa PubkeyAcceptedKeyTypes +ssh-rsa 完整的配置如下: Host jum...
Default is an empty list, which can be set as a variable when applying the role. If custom list is provided - it will be used to setHostKeyAlgorithmsinsshd_config The only difference from Macs and Kex, is that this setting will be honoured only from version 5.8 of SSH daemon, as earl...
How to configure specific mac, ciphers, KexAlgorithms, hostkeyalgorithms and pubkeyacceptedkeytypes for sshd service in RHEL 9? Security scanners regards specific algorithm and ciphers for ssh as vulnerable and hence there is requirement to modify these parameters in sshd_config to fix the vulnerabili...
