Bash Script to pull ipa server name on 500 servers
Hello All,
I need help writing a bash script that will run on 500 LINUX servers and do the following:

1. Capture the ipa_server name from /etc/sssd/sssd.conf on a list of 500 servers in the ipahosts file.

2. Write to a file outputing only server name and IPA server name.


Root ssh keys are enabled on all servers so automated login will occur. I really need help just extracting ONLY the IPA server information out of the file. I was playing around with grep and awk but haven't figured out the exact syntax.

Appreciate any help with this, Thanks


So far I have this:
Code:
#!bin/bash
for i in $(cat ipahosts)
do
hostname
cat /etc/sssd/sssd.conf >>ipa_servers_list
done

ipa-client-automount

ipa-client-automount(1) 					 IPA Manual Pages					   ipa-client-automount(1)

NAME

       ipa-client-automount - Configure automount and NFS for IPA

SYNOPSIS

       ipa-client-automount [OPTION]... <location>

DESCRIPTION

       Configures automount for IPA.

       The automount configuration consists of three files:

       o      /etc/nsswitch.conf

       o      /etc/sysconfig/autofs

       o      /etc/autofs_ldap_auth.conf

       By  default  this will use DNS discovery to attempt to determine the IPA server(s) to use. If IPA servers are discovered then the automount
       client will be configured to use DNS discovery.

       If DNS discovery fails or a specific server is desired, use the --server option.

       The default automount location is named default. To specify a different one use the --location option.

       The IPA client must already be configured in order to configure automount. The IPA client is configured as part of a server installation.

       There are two ways to configure automount. The default is to use sssd to manage the automount maps. Alternatively autofs can configured	to
       bind to LDAP over GSSAPI and authenticate using the machine's host principal.

       The nsswitch automount service is configured to use either sss or ldap and files depending on whether SSSD is configured or not.

       NFSv4 is also configured. The rpc.gssd and rpc.idmapd are started on clients to support Kerberos-secured mounts.

OPTIONS

       --server=SERVER Set the IPA server to connect to

       --location=LOCATION
	      Automount location

       -S, --no-sssd
	      Do not configure the client to use SSSD for automount

       -d, --debug
	      Print debugging information to stdout

       -U, --unattended
	      Unattended installation. The user will not be prompted

       --uninstall
	      Restore the automount configuration files

FILES

       Files that will be always be configured:

	      /etc/nsswitch.conf

       Files that will be configured when SSSD is the automount client (default):

	      /etc/sssd/sssd.conf

       Files that will be configured when using the ldap automount client:

	      /etc/sysconfig/autofs

	      /etc/autofs_ldap_auth.conf

EXIT STATUS

       0 if the installation was successful

       1 if an error occurred
