ssh 不按照 config 执行

Question

ssh 不按照 config 里的配置执行
比如说我在 .ssh/config 里做了如下配置

Host *
   ServerAliveInterval 60

Host hui.lu
    HostName hui.lu
    IdentityFile ~/.ssh/id_rsa_hui_lu
    Port 22

然后当我通过 ssh hui.lu 时，会出现下列提示

Received disconnect from {IP}: 2: Too many authentication failures for cloverstd
Disconnected from {IP}

然后我加上 -v ，发现 ssh 会不停的尝试我的其他 key

我的 .ssh 是放在 dropbox 里，并且通过软链接到 $HOME

在 .ssh/config 里添加 IdentitiesOnly yes，可以正常工作了

Answer 1

debug1: identity file /Users/username/.ssh/hui.lu type 1
debug1: key_load_public: No such file or directory

你 ls 看有没有 /Users/username/.ssh/hui.lu 这个文件。
