The shell script attached to this article will attempt to find the Web Tier installation directory, as well as look up the Authentication Manager, Web Tier and Virtual Host fully qualified host names from the Web Tier configuration.
Next, the shell script will perform name resolution of the fully qualified host names and check the status of ports 7022/TCP and the virtual host port, which by default is 443/TCP.

Installation

1. Download the attached wtcheck.sh shell script into the /tmp folder on a Web Tier instance that is running on a supported Red Hat platform.
2. Change the permissions of wtcheck.sh so it can be executed at the command line:

chmod 755 /tmp/wtcheck.sh

Usage

1. Logon to the Red Hat platform with a local account, either in an SSH session or at the local console.
2. Change the privileges of the local account using the command sudo su -.

rsaadmin@am82p:/opt/rsa/am> sudo su -
rsaadmin's password: <enter operating system password>
am82p:~ #

If you do not change the privileges of the local account, then the following message appears: You must be the root user to use this program; exiting...

3. Navigate to the /tmp directory:

cd /tmp

4. Use the wtcheck.sh shell script to check name resolution and port accessibility:  

./wtcheck.sh

Example output where the web tier is not in the default folder:

[root@webtier01-csau-ap-rsa-net tmp]# ./wtcheck.sh
