本地配置两个 github 账户，其中一个正常，一个有问题，求教？

[higocn]

其中有问题的账户：
1. 公匙已正确添加， htts 可以访问；
2. 连接报错

···
ssh_exchange_identification: Connection closed by remote host
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
···

3. ssh [e-mail] -vT 测试有问题的输出：

···

config 文件贴了看下。

[higocn]

@Dashit config
Host git.mydomain.com
Port 65422
HostName git.mydomain.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/aaa_rsa

Host github.com
HostName github.com
User myname
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa

Host *
IdentitiesOnly yes

我发现在公司两个都可以访问，在家就只有上边那个可以访问。

@higocn 我也是用这种方法弄的。看日志像是 ssh key 的问题。 wifi 情况生成的 ssh key 连网线是不能用的。没有这种情况吧。

[higocn]

@Dashit
我都是 wifi 生成的， key 应该没问题， 因为在公司网，两个都是正常访问的。只有在家里，是底下那个不能访问。

把私钥文件名改回 id_rsa 试试。
Tip: On most systems the default private keys (~/.ssh/id_rsa, ~/.ssh/id_dsa and ~/.ssh/identity) are automatically added to the SSH authentication agent. You shouldn't need to run ssh-add path/to/key unless you override the file name when you generate a key.
