ssh 配置主机限制

Question

我有一些问题 ~/.ssh/config. 我有 300 台主机，我需要以 root 身份而不是我自己的身份获得这些主机。我编写了为我创建配置文件的脚本，它为我提供了四行配置文件：

host *
    user me
host <here 300 hostnames seperated by space and in this same line all>
    user root

当我想通过 ssh 连接到任何服务器时，我收到消息，我有一个 'bad configuration in line: 10' 或“...第 6 行”:/

wc -l .ssh/config

给我 4

Answer 1

当前的 OpenSSH 应该最多读取 4096 bytes long lines. But versions before OpenSSH 7.5 were reading only 1024 bytes, which might not be enough (commit)。

你有两种可能：

更新到 OpenSSH 7.5

将行剥离为不超过 1024 个字符的较短行，例如

host <here first 100 hostnames seperated by space and in this same line all>
        user root
    host <here another 100 hostnames ...>
        user root
    host <here another 100 hostnames ...>
        user root
