Linux TACACS&x2B；当磁盘只读且用户是系统新用户时，密码已损坏

我们有一些实例，由于内核错误，磁盘变成只读。 当磁盘处于只读状态时：

 Decrypted Request
        Flags: 0x00
        User length: 4
        User: \b\n\r\177    <-- password, which should have been "pass"
        Data length: 0

Decrypted Request
    Flags: 0x00
    User length: 4
    User: pass     <-- password is as expected "pass"
    Data length: 0

当您以以前的远程用户身份登录时，一切正常。TACACS身份验证成功

但当您以新远程用户身份登录（在此设备中，以前未登录用户）时，发送到TACACS服务器的密码已损坏。因此，身份验证失败

你知道是什么导致了这种腐败吗

登录失败时从数据包捕获：

        User: \b\n\r\177    <-- password, which should have been "pass"
