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.
