我无法通过密码登录我的服务器，即使我通过 明确设置了用户的密码usermod。我已PasswordAuthentication yes在我的 中设置sshd_config并重新启动了 ssh 守护程序。我甚至多次设置了用户的密码。但是，当我尝试登录我的服务器时，sshd 显示以下日志输出：
Jan 24 21:18:31 ip-10-36-13-72 sshd[11756]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=173.12.2.64 user=jimuser
Jan 24 21:18:34 ip-10-36-13-72 sshd[11756]: Failed password for jimuser from 173.12.2.64 port 15508 ssh2
目前我还不太清楚该去哪里找。有什么想法吗？
更新：
/etc/pam.d/sshd

答案1
首先要尝试使用 passwd 命令设置用户密码
# passwd jimuser
Changing password for user jimuser.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
如果这有效，那么一切都很好，但请注意，usermod 采用预先加密的密码字符串
-p, --password PASSWORD 加密密码，由 crypt(3) 返回。
如果你确实想提供预先加密的密码，那么有多种工具可供选择，例如sha1pass（perl 脚本）grub-墓穴（python）或者看看解决方案这里。
