Not Trusted System

To check whether an HP-UX system is trusted or not, you may run the below command:

# /usr/lbin/getprdef -r
System is not trusted.

The output of the above command shows that the system is not a trusted system. Here, I have run the above commands on HP-UX 11.31 system. If an HP-UX system is not trusted then you can’t implement some specific securities on the system like password policy etc.

Trusted System

There are many ways to check an HP-UX system is trusted or not, some are given below:

• If an HP-UX system is trusted then you will get the output like shown below for the above command.

  # /usr/lbin/getprdef -r
  NO, 0, 8, 182, 196, -1, 7, YES, YES, NO, NO, NO, YES, 3, 10, 2, 0

• Check the system and see if it has a /tcb directory then the system is trusted.

  # ll /tcb
  total 0
  drwxrwx--x   3 root       sys             96 Aug 25 11:41 files
  

• Check the second field in the /etc/passwd file, it should be an * for a trusted system.

  # cat /etc/passwd
  root:*:0:3::/:/sbin/sh
  daemon:*:1:5::/:/sbin/sh
  bin:*:2:2::/usr/bin:/sbin/sh
