修改密码时报错passwd: Authentication token manipulation error

passwd: Authentication token manipulation error 错误通常是由于权限问题引起的。要解决这个问题,你可以尝试以下几个步骤:
1. 使用 root 用户或具有 sudo 权限的用户进行操作。确保你有足够的权限来修改密码。
2. 确认文件系统是否以读写模式挂载。你可以运行以下命令来检查文件系统的挂载状态:
```
mount | grep " / "
```
如果你发现 `/` 分区以只读模式挂载,你需要将其重新挂载为读写模式。可以尝试以下命令:
```
mount -o remount,rw /
```
3. 检查磁盘空间是否已满。如果磁盘空间不足,可能会导致密码修改失败。你可以通过运行以下命令来检查磁盘使用情况:
```
df -h
```
如果发现磁盘空间不足,你需要释放一些空间后再尝试修改密码。
4. 如果以上方法都无法解决问题,尝试使用恢复模式来修改密码。恢复模式可以提供更高级别的权限。具体操作步骤可能因发行版而异,但一般情况下,你需要重启计算机并选择进入恢复模式(在启动时按下特定按键)。
如果问题仍然存在,请提供更多的上下文信息,例如操作系统版本和具体的命令使用情况,以便更准确地帮助你解决问题。

passwd: Authentication token manipulation error 如何处理?为什么不能修改密码?重启主机后也无法修改密码。/etc/passwd或/etc/shadow的权限都是644?还有其他解决办法么?
这个错误通常是由于文件系统的读写权限问题导致的,可能是由于文件系统已被挂载为只读状态或者文件权限不正确导致的。您可以尝试以下解决方法:
1. 检查文件系统是否已被挂载为只读状态。您可以使用以下命令检查:
```
mount | grep -w "/"
```
如果输出结果包含 "ro",则表示文件系统已被挂载为只读状态。您可以使用以下命令将其重新挂载为可读写状态:
```
mount -o remount,rw /
```
2. 检查文件权限是否正确。确保 /etc/passwd 和 /etc/shadow 的权限为 644,所有者为 root。您可以使用以下命令进行检查和修改:
```
ls -l /etc/passwd /etc/shadow
chown root:root /etc/passwd /etc/shadow
chmod 644 /etc/passwd /etc/shadow
```
3. 检查磁盘空间是否充足。如果磁盘空间不足,可能会导致文件系统出现错误。您可以使用以下命令检查磁盘空间:
```
df -h
```
如果磁盘空间不足,请尝试释放一些空间。
如果以上方法都无法解决问题,您可以尝试使用 Live CD 或其他可启动的介质进行修复。如果还是无法解决问题,建议您联系系统管理员或技术支持人员寻求帮助。
[root@localhost pam.dl## passwd operator Changing password for user operator. Bapasswd: Authentication token manipulation error
The error message you're encountering, "Bapasswd: Authentication token manipulation error," typically occurs when there's an issue with the PAM (Pluggable Authentication Modules) configuration while trying to change a user's password in Linux, specifically for the `operator` user.
In this case, it seems like you are using the `passwd` command, which is part of the `pam` (Pluggable Authentication Modules) system, to modify the password for the `operator` account, but an authentication error is happening during the process. This error could be due to several reasons:
1. Incorrect password policy: The system might not be allowing the current password to be changed according to the defined password policies (e.g., minimum length, complexity rules).
2. PAM module failure: A specific PAM module involved in the password change (like pam_cracklib or pam_duo) might be malfunctioning or not properly configured.
3. Token manipulation issues: It could indicate a problem with the authentication token, which might be invalid or temporarily unavailable.
4. Permission problem: The user running the `passwd` command may not have the necessary permissions to change the password for the `operator` account.
To troubleshoot this issue, try these steps:
- Check the PAM configuration file (`/etc/pam.d/passwd`) and ensure the relevant modules are correctly set up.
- Ensure the user running the command has the proper privileges, such as being a member of the `wheel` group, which usually allows password changes.
- Verify that the password strength requirements are met if there are any.
- Temporarily disable security modules (if any) to see if the error persists and then re-enable them one by one to isolate the problematic module.
