Root Privileges in PI 3.1

[MUQ_1899_]

Hello,

Until PI 3.1 root access to the Linux shell was permitted by default. Now in PI 3.1 it is not. Is there any way to gain root privileges to this shell?

You can no longer "su" to become root. However they do allow you to "sudo" to perform commands requiring escalated privilege.

For example:

ade # ls -al
ls: cannot open directory .: Permission denied
ade # sudo ls -al
total 84
dr-xr-x---. 6 root root 4096 Jul 19 11:07 .
dr-xr-xr-x. 30 root root 4096 Jul 19 11:14 ..
drwxrwxr-x. 4 root root 4096 Jun 3 17:09 .matlab
drwxr-xr-x. 2 root root 4096 Jun 3 14:19 .oracle_jre_usage

ade # sudo vi script.sh
[sudo] password for bob:
Sorry, try again.
[sudo] password for bob:
bob is not in the sudoers file. This incident will be reported.

ade # sudo -s bob
[sudo] password for bob:
bob is not in the sudoers file. This incident will be reported.

This is happening when I try to execute a command with super user privs.

 - What about my original suggestion :

      # sudo -s

(without any further parameters!). Further more , it only works if you logon with the default admin account onto prime. The gotcha is that if you use a none-admin account-(name) it won't work (indeed).

That worked. :)

If default “admin” account was not created at installation time, then create it while logged in as your alternate admin account.

host/sysadmin# conf t
host/sysadmin(config)# username admin password plain PASSWORDNEW role admin
host/sysadmin(config)# exit
host/sysadmin#

 - Provided the default admin account is being used for initial logon :

            # sudo -s

Should give  you a root shell
