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

       If "AuthorizedKeysCommand" is supported, sshd(8) can be configured to use it by putting the following directive in sshd_config(5):

	   AuthorizedKeysCommand /usr/bin/sss_ssh_authorizedkeys

       If "PubkeyAgent" is supported, sshd(8) can be configured to use it by using the following directive for sshd(8) configuration:

	   PubKeyAgent /usr/bin/sss_ssh_authorizedkeys %u
