Installing Cisco DCNM on Red Hat Linux

DCNM is Cisco’s GUI for managing MDS and Nexus products.  It’s pretty great for getting a visual of how things are configured and performing. I thought I would go into a little more detail than I’ve seen posted online about installing DCNM on RedHat Linux.  In this example we’ll be installing two servers.  One server […]

Configure VMware from scratch without Windows

One of the things that bugs me about vCenter (still) is that it is still very tied to the Windows operating system.  You have to have Windows to set it up and trying to go about without Windows is still somewhat difficult.  In my lab I’m trying to get away from doing Windows.  I have […]

FCoE with UCS C-Series

I have in my lab a C210 that I want to turn into an FCoE target storage.  I’ll write more on that in another post.  The first challenge was to get it up with FCoE.  Its attached to a pair of Nexus 5548s.  I installed RedHat Linux 6.5 on the C210 and booted up.  The […]

MediaWiki Installation on RedHat 5.5

In modern data center things like IPs, user accounts, passwords, and such that you used to keep in Excel spreadsheets should be rolled into the management tools.  That way, you always have the most current information.  Static word, excel and the like are old news.  Today you can see those things start to get rolled […]

Problem of the day is I have a computer that is on some local intranet that can not SSH out into the real world.  There is however a proxy server on my network that I can configure in my browser to get outside internet access… But I want ssh.  So… after a bit of internet […]

IBM Advanced Management Module Java Setup for Linux

More notes on ESXi 4.1 Kickstart

ESXi 4.1 kickstart is adequate for most things but I still have several issues with it that I consider ‘bugs’: 1.  If you’re not connected to a network, it doesn’t work.  This is fine since most people will be on a network with VMware anyway right?  Fine, I’ll let this one slide.  But if you […]

opening VNC from behind a firewall

Here is the cast of characters: 1. blopr: A server that is behind a company firewall that I want to view its vnc session 2. netnet: A server that is on the internet that I have access to. 3. Me: The humble system admin who wants to view the VNC session on blopr. Here is […]

Server to Switch Port mapping with SNMP

Let’s say you have a switch.  And you are on a computer that is connected to the switch.  You know the following: The name of the switch The SNMP community string and version the switch uses. But, you’re too lazy to walk over to the data center to figure out which port you’re connected on. […]

KVM with RHEL5.4

Installing KVM with RHEL5.4 is pretty easy.  These were some of my notes that I hope you can somewhat follow along with. I have since done it with RHEL5.5 with the same results. Here’s how I got my virtual machine up: 1. Install Packages [cc lang=”bash”] yum -y install kvm python-virtinst libvirt libvirt-python virt-manager virt-viewer […]
