Graylog has been through some changes last time I talked about them, hitting version 3.0 in February is awesome and one of things that make Graylog run well is Elasticsearch backend. Although Elasticsearch is not too hard to setup it usually runs better on bare metal, so there is cost of that as well as maintenance of the cluster is important, updates and upgrades. Depending your team experience you may not have time to learn it or run it the way it should be. That last thing you want is your logging setup to go down because of poor maintenance.
So in this post we will walk though setting up a Graylog Server and using AWS Elasticsearch service for our backend. Without having a quick Elasticsearch cluster Graylog experience suffers, so let’s get started.

I keep doing the automation dance, there are a lot of different tooling products out there. I have been trying to understand a use case around using it with network automation. Recently I have been dancing around with Ansible. My personal belief is that using any type of these tools would be helpful but it can be a steep learning curve if you really don’t have any programming knowledge. This is not something that is relatively easy to use or understand, don’t expect to have a working network automated tool in production on day one. I think this is great for learning, and using this in a network sandbox. If you don’t have programming mindset it might make your job harder on day one before it gets easier, but just like learning to dance you have to learn the steps, the moves, and maintain the rhythm. So with that let’s at least figure out the starting points, and begin learning the steps of the automation dance. 😉 Continue reading “Automation Dance”
Although GNS3 can run local on your computer and you can use VMware Workstation and have the GNS3 appliance. I found it much more stable and predictable to run GNS3 on a dedicated server. Using this type of installation, all the projects, and images are stored on the GNS3 server, so I can install the GNS3 client any computer and get access to the same projects I was working on. You can also have multiple people working on different projects that are on the same server. I find that neat for educational use or if you where helping someone with a project. In this post I’ll walk though the steps needed to set up a GNS3 server.

It’s been almost 24 hours since GNS3 launched a campaign to bring in funds to support the open source network simulator and bring it up to version 1.0. A lot of new features are on the list, like switching, cloud processing, hassle free configuration, labs/training materials and 3rd party integrations. All of which are in the works for this new version added along with some pretty cool plug-ins. As of writing this post they are at $106,973 dollars which is 300 percent over funded! A pretty good turnout in fact they meet their goal in less than 4 hours of stating the campaign and have 16 days left to go. Continue reading “GNS3 1.0 Campaign”
