cygwin 和 debian wheezy 之间的 ssh

cygwin 和 debian wheezy 之间的 ssh

我正在尝试连接桌面（win7 x64）和笔记（debian wheezy x32）。已完成 ssh cygwin 和 debian 的标准安装。创建公钥并通过 usbflash 将其移动到~/.ssh/authorizwd_keys和~/.ssh/

在 cygwin 中制作

cd ~/.ssh
chmod 700 id_rsa

然后尝试连接并记录

debug1: ssh_ecdsa_verify: signature correct
debug1: SSH2_MSG_NEWKEYS sent
debug1: expecting SSH2_MSG_NEWKEYS
debug1: SSH2_MSG_NEWKEYS received
debug1: Roaming not allowed by server
debug1: SSH2_MSG_SERVICE_REQUEST sent
debug1: SSH2_MSG_SERVICE_ACCEPT received
debug1: Authentications that can continue: publickey,password,keyboard-interactive
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /home/A/.ssh/id_rsa
debug1: Authentications that can continue: publickey,password,keyboard-interactive
debug1: Trying private key: /home/A/.ssh/id_dsa
debug1: Trying private key: /home/A/.ssh/id_ecdsa
debug1: Trying private key: /home/A/.ssh/id_ed25519
debug1: Next authentication method: keyboard-interactive
debug1: Authentications that can continue: publickey,password,keyboard-interactive
debug1: Next authentication method: password

UPD 检查文件权限，将日志级别更改为 DEBUG。然后我尝试连接，但日志中没有写入任何内容，只有关于重新加载服务的信息

UPD 尝试在 cygwin 中使用命令“ssh -vvv”进行连接，结果出现错误

"debug3 Incorrect RSA1 identifer" 
"debug3 Couldnt load "/home/A/.ssh/id_rsa" as RSA publick key"

客户端不会显示诸如“使用方法‘publickey’和某某密钥进行身份验证失败”之类的消息，因此，为了正确地调试此问题，请在您的 Debian 服务器上按照以下清单进行操作：

  1. 确保~/.ssh用户目录的权限不要太宽松。

    user:user它通常应该由（user服务器上用户的名称在哪里）拥有并0700在其上设置权限位。

  2. 确保~/.ssh/authorized_keys文件是user:user和0600。

  3. 编辑/etc/ssh/sshd_config（注意字母“d”——您需要服务器的配置文件）并提高其日志记录级别：

    LogLevel DEBUG

    保存文件并重新加载服务器的配置：

    # service ssh reload

  4. 现在执行另一次登录尝试并检查sshd写入的内容/var/log/auth.log。

  5. 将设置恢复LogLevel为其标准值，INFO然后再次重新加载配置。
