Heartbleed - Heartbeats - and other Heart filling stories

CFML Server, cfObjective, Chit Chat, ColdBox, Conferences, OpenSSL, Server Admin

Yes, I still have a heartbeat, although my blog didn't have much of one for a while, that is true. The heart filling story, is that my mum and dad flew in the day after my last blog post, so I've been spending a lot of time with my parents, sharing experiences with their grandchildren. They live in New Zealand, so they do not visit too often, and my busy life got even busier. I have been busy, but you have to wait and see the fruit of my labor, more about that below. Of course, this week, you can't go far without talking about Heartbleed, so I have a few tips for those of you fighting Heartbleed too

Moving SSL certs from IIS on Windows to Apache on Centos

Apache, OpenSSL, Server Admin

We're migrating a series of Windows Servers to Centos, and in doing so, there are a number of SSL Certificates that need to be migrated too. Going through the whole process of creating new Requests invalidates the old SSL, so it can be a tricky transfer process, and in migrations, you want to try and streamline them as much as possible, so we wanted to export our SSL Certs ahead of time, import them and be prepared. To see how to export SSL Certs from IIS 6 to a .pxf here, I will add a few other walkthroughs for other versions as I complete them.

Exporting SSL Certificates from IIS 6 on Windows into .pfx files

OpenSSL, Server Admin

Working with Windows and IIS, you might come across the time when you want to move an SSL Certificate from one server, to another server, and you wonder how you can do this without starting a new request, and go through the whole process again. If you have the .cert .crt or .cer file, you can try and import it into IIS, but you'll realize, you need the CSR generated from the new IIS server, for the .cert .cer .crt file to match it, so you'll have to export the SSL cert to a .pfx. This makes moving SSL Certs from IIS Server to IIS server, but it also allows you to take the SSL and move it to an Apache httpd server using Openssl. This little guide will walk you through creating the .pfx file, preparing for importing it into your new Web Server, whatever you decide to use.

Dev Ops - From Mail Logs to DB Stats in a CFML Dashboard - Part 4

CFML Language, Server Admin

Welcome back to the fourth post in this mini series on how to take some Mail Logs from our qmail servers, and massage them and move them around, and finish with them on a cfml box ready to massage them a little more, and make some pretty and readable graphs and tables, to keep our Mail Servers in the good books, and off those pesky Spam Blacklists. In post onetwo and three, we found the files, identified what we wanted out of the log files, planned out how we were going to use cron to move files, reset perms, and finally grep the important stuff out of the logs, and get it ready for our cfml engine to do its thing.

Dev Ops - From Mail Logs to DB Stats in a CFML Dashboard - Part 3

Server Admin

This is our third post in this mini series. You can read the first and second posts here. We know what we want out of the log files… so lets setup the process of getting the logs moved, and get the "goods" out of them… and in a position for our CFML Agent to do its job. We want to keep separation of duties on the servers, so we have Server A with Mail running, and the log files… and we want to move them to Server B… massage them, and prep them for CFML. So lets setup our cron jobs on Server A.

Dev Ops - From Mail Logs to DB Stats in a CFML Dashboard - Part 2

Server Admin

In the first post in this series, I mentioned that lately I have had a lot more Dev Ops duties than in the past. I am sharing my process as I try and solve a problem, keeping up with our qmail Mail Logs, to look for potential risky behavior, because our Servers get blacklisted. I'm using a few technologies, with the end goal, getting the log data in a useable format for ColdFusion / Railo CFML to crunch the data, and make it look pretty in a CFML Dashboard. Read the first post here to get up to speed.

Server Admin - From Mail Logs to DB Stats in a CFML Dashboard - Part 1

CFML Language, Server Admin

Lately, I have had a lot more Server Admin / Dev Ops duties than in the past… I am really enjoying a different type of problem solving as I am trying to leverage Dev Ops to increase automation and efficiency. I thought it might be interesting to map out my latest little project, one for my own learning, two for the purpose of sharing, and three for feedback on what I am doing wrong and what I could improve. This is Part 1 of a short series as I explore my problem, and how I find a solution.

As a Web Hosting Company, we obviously host websites, and a lot of Email Accounts for our Customers. These days, with Spam, you have to really be on top of your game, otherwise in a blink of an eye, your servers can get blacklisted, and you're constantly fighting to get your servers off blacklists, because it hurts each and every email customer on that server. Bad passwords, accounts being hijacked, viruses, and users sending out too many messages, or possibly bad messages, are just some of the things you get blacklisted for.

Techie Gotcha - SSL Certificate Problems with Apache and Issuer Chain

Apache, OpenSSL, Server Admin, Techie Gotchas

I am sure SSL Certificates are not new to most Web Developers, unless you have the luxury of an Admin team. I have been using them for years, most of those years admittedly on Windows, but the last several years we have been migrating all of our windows boxes over to Linux (as you could tell from the majority of my posts). Just recently though, something new came up, which I had not seen before, so I thought I would share my experience, for anyone else looking for a solution out there.
