How to pass root password with su and command?
Hello,
I have list of around 400 devices. I need to restart a service /etc/init.d/psap23.sh in all of them, but it should restart by root only.
Those have some other kind of light Linux. There is no sudo package in that and we can't/shouldn't install. Direct root login is not allowed. I login with user gis and do su to root and then restart that service.
All are having same password for gis and same password for root
Is there any way, I can pass command with some loop instead of login on them one by one ?
I have Mobaxterm and I can run for loop from them. Also, I have ansible, if there is any option to do it.
Please suggest.
Thanks

login.krb5

LOGIN(8)						      System Manager's Manual							  LOGIN(8)

NAME

       login.krb5 - kerberos enhanced login program

SYNOPSIS

       login.krb5 [-p] [-fFe username] [-r | -k | -K | -h hostname]

DESCRIPTION

       login.krb5  is a modification of the BSD login program which is used for two functions.	It is the sub-process used by krlogind and telnetd
       to initiate a user session and it is a replacement for the command-line login program which, when invoked with a  password,  acquires  Ker-
       beros tickets for the user.

       login.krb5  will  prompt  for a username, or take one on the command line, as login.krb5 username and will then prompt for a password. This
       password will be used to acquire Kerberos Version 5 tickets (if possible.) It will also attempt to run aklog to	get  AFS  tokens  for  the
       user.  The  version 5 tickets will be tested against a local krb5.keytab if it is available, in order to verify the tickets, before letting
       the user in. However, if the password matches the entry in /etc/passwd the user will be unconditionally	allowed  (permitting  use  of  the
       machine in case of network failure.)

OPTIONS

       -p     preserve the current environment

       -r hostname
	      pass hostname to rlogind.  Must be the last argument.

       -h hostname
	      pass hostname to telnetd, etc.  Must be the last argument.

       -f name
	      Perform pre-authenticated login, e.g., datakit, xterm, etc.; allows preauthenticated login as root.

       -F name
	      Perform pre-authenticated login, e.g., datakit, xterm, etc.; allows preauthenticated login as root.

       -e name
	      Perform pre-authenticated, encrypted login.  Must do term negotiation.

CONFIGURATION

       login.krb5  is  also  configured via krb5.conf using the login stanza. A collection of options dealing with initial authentication are pro-
       vided:

       krb5_get_tickets
	      Use password to get V5 tickets. Default value true.

       krb_run_aklog
	      Attempt to run aklog. Default value false.

       aklog_path
	      Where to find it [not yet implemented.] Default value $(prefix)/bin/aklog.

       accept_passwd
	      Don't accept plaintext passwords [not yet implemented]. Default value false.

DIAGNOSTICS

       All diagnostic messages are returned on the connection or tty associated with stderr.
