我有一个 Ubuntu 8.10 版本，其中运行着 OpenSSH 版本 5.1p1。我创建了一个新用户帐户，设置了密码，然后使用以下命令使其过期：
chage -d 0 username
我想强制用户在第一次登录时更改其过期的密码。
当用户启动新的 PuTTY SSH 2 连接时，他们会输入用户名和正确的密码。但是，系统并未提示用户更改过期的密码，而是关闭会话并显示以下 PuTTY 致命错误：
“服务器意外关闭网络连接”
为了进一步调查，我使用以下命令在不同的端口上以调试模式启动了新的 sshd：
/usr/sbin/sshd -ddde -p 1022
然后我尝试登录这个新的 SSH 端口。这是我的输出：
debug1: userauth-request for user username service ssh-connection method password
debug1: attempt 1 failures 0
debug2: input_userauth_request: try method password
debug3: mm_auth_password entering

似乎我没有收到来自 的正确消息pam_acct_mgmt。我是不是没有以正确的方式使密码过期？我该如何解决这个问题？谢谢！

您可以只使用passwd -e username。该命令chage -d 0 username将上次登录设置为 1970 年 1 月 1 日。
