we have four servers which are supposed to be exactly same, but over the time some differences have been made on them, for example some packages have been installed on one of them and not others, or the RAM and CPU is different, and also some of them are on vmWare ESX, so we'll need to get RVtools information as well. I need someone who is expert in Linux Redhat and can do scripting on Python. The job is about writing a script to get the information of a Linux server and generate an XML file from it, and by information I mean any details about the server, from CPU, RAM to the hostname, DNS, running services, users, raid controller, storage and other characteristics that is specific for that server, I also have a sample that I found on the internet that is attached. This is job is super urgent and the bonus would be very good. so please let me know if you are available right now, when we present the initial draft to my client, we will then continue to complete it during next 5-6 days. We dont have access to the servers for security reasons, so you should have Linux Redhat in your lab. I already have two different codes written by two people but there are some problems, need to review those and based on the client's feedback fix them.

I'm looking to install mod_pagespeed on my server running CentOS 6.8 and cPanel with EasyApache3. I have attempted to install it previously but keep running into issues with "httpd >= 2.2 is needed by mod-pagespeed". I know this is something to do with cPanel is compiled but I am not technical enough to know how to resolve this. This should be a quick, simple task for someone who is competent.

I'm looking for a system administrator with experience in Let's Encrypt. I've tried to install the certificate myself, but I run with some errors. The VPS is running Centos 7 with Apache, WHM/Cpanel, a DNS server and mail server, and it already has emails and a website in operation. The main problem is that emails are arriving to spam or not being sent at all, and I think it's because the certificate is invalid. I need the certificate for the main domain (let's call it mysite.com) as well as subdomains mail.mysite.com and balsrv.mysite.com. The MX records are pointing to mail.mysite.com, but the SSL/TSL configuration, according to Cpanel, must be to balsrv.mysite.com, though the MX records are not pointing to that subdomain. I also tried with Let's Encrypt for cPanel, which costs $30, but I'm using the trial version, which will last three days. The problem is that I can't add the email subdomains from the Cpanel account to issue the certificates there, because those subdomains are server-wide and not specific to the Cpanel account. Please ask me any questions if you need more information. If you don't, and are already up for the job, please tell me how many hours it will take from you; don't just say you will take it without saying how much it will cost. Also, I will not give you passwords until you are hired. Regards

I need PMTA Installed on a base Linux distro (whatever you prefer) with an open source control panel of your choice. I will not use CPanel or another commercial panel. In the past we have used Virtualmin. We will have 8 domains that will need to send with this configuration. The autoresponder software is already on a separate machine so domains must use individual names and passwords as auth for sending. Each domain MUST report only it's own IP when sending email (not the IP of the host machine), and you must create and confirm all dns records including but not limited to spf, dkim and dmarc.
