问题：无法使用 Git 从 Windows 推送到 Linux。也无法通过 ssh 连接到 git 用户。
更新 #1：我将“PasswordAuthentication”改为 no 并进行了测试。密钥不起作用，但密码起作用。显然与 ssh-rsa 密钥有关。
更新 #2：尝试生成一个与我的用户帐户不同的全新密钥。密钥仍然被拒绝，问题相同。
更新 #3：问题已解决，答案已发布。由于我使用的程序无法读取 .ppk 文件，因此日志实际上毫无用处。
运行 CentOS 6.4，整个驱动器被加密，主文件夹未被加密。
我在 Windows 上使用 git 推送到服务器上的 git repo。基本上遵循以下步骤：http://git-scm.com/book/en/Git-on-the-Server-Setting-Up-the-Server
我以前在 fedora 和 debian 上用过，一切正常……但不知道这里发生了什么。我首先想到的可能是主文件夹被加密了，但文件夹并没有加密。
我尝试再次复制密钥并删除用户并将其添加回来。我尝试仅使用 ssh 连接到“git”用户，并得到了以下日志。不完全确定是什么原因导致了这个问题。
这是我 Windows 机器上的配置文件。
获取和拉取是：ssh://name1/opt/git/git.project
配置文件：
Host name1
HostName name2.com
Port 12345
User git
IdentityFile ~/.ssh/private_key.ppk
事情的经过如下：
USER_NAME@MY-PC ~/Documents/Workspace/git.project (master)
$ ssh -vT -p 12345 -i "C:/Users/USER_NAME/.ssh/private_key.ppk" git@WEB_NAME.

答案1
步骤1：
chmod 700 ~/.ssh
第2步：
chmod 600 ~/.ssh/authorized_keys
步骤3：
sed -i 's|#AuthorizedKeysFile|AuthorizedKeysFile|g' /etc/ssh/sshd_config
sed -i 's|.ssh/authorized_keys|%h/.ssh/authorized_keys|g' /etc/ssh/sshd_config
注意：根据需要添加“sudo”。
我从来没有在其他 Linux 发行版上这样做过，真的很惊讶我需要这样做。
