Configuring Rancid

In my last post I talked about installing Rancid on Centos 7 so be sure to check that out. In this post we now want to actually use Rancid so I’ll walk through on how to setup Rancid to login into network equipment and get configurations. To recap: Rancid is a great tool to help monitor a device configuration for any changes. It also keeps track of them by using CVS (Concurrent Version System) for backups, so you can go back and compare versions or revert to a previous configuration. Rancid supports multiple hardware from Cisco, HP, Dell, Juniper and more. This is all open-source so you can create custom scripts or add commands to really make this a personal repository that fits your company. Continue reading

Setting up GNS3 1.1 on Ubuntu

gns3_logoIt’s only been a week since GNS3 1.0 was released and it’s already been updated to 1.1 so in this post I have Ubuntu 14.04 LTS with the latest updates and its time to set up GNS3. GNS3 is an open source tool that helps network professionals run a virtual network right on their computer, GNS3 is not a simulation program but rather an emulation program. So if you wanted to test a configuration change but did not want to run it on production you can run it in GNS3 instead.  This gives network professionals testing without touching any physical hardware or purchasing that expensive test lab for certification studies. Let’s get started. Continue reading

GNS3 1.0 Campaign

GNS3-logoIt’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

Is Your Network Healthy?

heart-healthy-netNetworks are becoming more “borderless” as Cisco likes to call it and it’s definitely true. Having the ability to get access to resources remotely without having to be at our office physically is a nice touch, you may even notice higher productivity and who doesn’t want that! Networks have to be in a healthy state in order for people remotely and people at the office to get their work done. An unhealthy network at a business usually loses productivity and customers which in the end comes down to money. How do you know if your network is reaching its capacity along with the general health state of it? Let’s look at some commands and general best practices! Continue reading

Site-To-Site VPN via CCP

security-gallery-01258I have ran through before on how to create a site-to-site VPN with Cisco SDM which sounds like a repeat but I thought why not bring CCP into light and since I’m studying the newly created CCNA Security (640-554) I figured let’s create a tutorial on it. In this lab I am going to post the running-config of both locations so you can either run it through Packet Tracer or live equipment if you wish. I am running two Cisco 2811s with Advanced Security Version 12.4(24)T8. Let’s do it! Continue reading
