ssh仍在为ssh服务器提供错误的ssh密钥。
以下是我尝试的内容：
ssh -T -i ~/.ssh/my_new_id_rsa git@my-new-host -v
并在.ssh/config
Host my-new-host
Hostname github.com
IdentityFile ~/.ssh/my_new_id_rsa
User git
ssh -T的输出是：
ssh -T -i ~/.ssh/my_new_id_rsa git@my-new-host -v

与debug1: key_load_public: No such file or directory有什么关系？
如果它同时存在/Users/snowcrash/.ssh/my_new_id_rsa和/Users/snowcrash/.ssh/my_new_id_rsa.pub。
并进行额外的调试：
ssh -T git@my-new-host -i ~/.ssh/my_new_id_rsa -vvv

====更新1
我的~/.ssh/config包含
主持人* 身份只有是
====更新2
如果我运行cd ~/.ssh和rm id_rsa*，那么它会提供正确的ssh密钥。
答案 0 :(得分：0)
默认情况下，ssh会提供默认位置的密钥。如果您想更改此行为，则需要在IdentitiesOnly yes中使用ssh_config选项。
