linux - Git 权限被拒绝(公钥、gssapi-keyex、gssapi-with-mic)？

Question

客户端:操作系统 Ubuntu，git-version 2.7.4。

服务器:OS Centos，git-version 2.7.4。

我的客户端有私钥，服务器有公钥。

我可以使用 shell 进入我的服务器(没有密码)。

但是不能推送 origin master !

'whjwebsite'是我的私钥。

drwx------.ssh/

-rw-------- whjwebsite

服务器:sshd_config:

```RSAAuthentication 是PubkeyAuthentication 是GSSAPIAuthentication 是GSSAPICleanupCredentials 否使用DNS没有地址家庭网络PermitRootLogin 是系统日志设施 AUTHPRIV密码认证号ChallengeResponseAuthentication no

我的 2 美分:在服务器端，禁用 GSSAPIAuthentication(即由 Kerberos 支持的 SSO)，除非您在企业防火墙内的 Linux 上使用 Active Directory 身份验证(使用 Centrify 或 SSSD)。

如果您确实处于 SSO 场景中，但由于某种原因单点登录无法开箱即用，则使用客户端选项绕过 Kerberos，例如

ssh -o GSSAAPIAuthentication=no -o GSSAPIKeyExchange=no
