Pimp My Microserver!

I’m not normally in the habit of posting this sort of thing but I do own a number of these MicroServers and they’re great for home lab use. They may only take up to 8Gb RAM and have single, dual-core chips in them but they don’t eat much power and don’t make much noise. They’re also as “cheap as chips” to buy! Enough about why I have them. ServersPlus are running a competition of sorts to design a cosmetically pimped up MicroServer. If you submit what becomes the winning design you get the first one of the batch for free. Submissions have to be in on 11th November and voting runs until 30th November.

Creating VLANs in DD-WRT (Part 3)

In the second part of this post I completed the setup of VLANs on my WNR3500L router. To make them available to hosts (and VMs) I now have to configure my Cisco SLM2008 switches. Fortunately that turns out to be fairly simple. The SLM 2008 has a web-based GUI that does the job nicely. Once logged in it’s a matter of opening the VLAN >> VLAN Settings page. Then just tap in the VLAN ID that you want to create and click “Add”. This then drops you into an additional page where you choose which ports to associate the VLAN with. I picked all of the ports on this switch (where my ESX hosts are located). Then I clicked “Save”. It’s just then a case of repeating for the other VLANs that are required. And that’s the switches done. The default configuration […]

Creating VLANs in DD-WRT (Part 2)

In the first part of this post I created some VLANs on my NetGear WNR3500L router that I’ve flashed with DD-WRT firmware. In this second part of the post I will be assigning IP address ranges to those VLANs and configuring the router’s firewall. I want the VLANs that I setup previously to use separate IP Address ranges. To do this it’s back into to the telnet session and enter the following command: [text]nvram set rc_startup=’ #!/bin/ash PATH="/sbin:/usr/sbin:/bin:/usr/bin:${PATH}" ifconfig vlan6 192.168.6.254 netmask 255.255.255.0 ifconfig vlan7 192.168.7.254 netmask 255.255.255.0 ifconfig vlan8 192.168.8.254 netmask 255.255.255.0 ifconfig vlan9 192.168.9.254 netmask 255.255.255.0 ifconfig vlan10 192.168.10.254 netmask 255.255.255.0 ifconfig vlan11 192.168.11.254 netmask 255.255.255.0 ifconfig vlan12 192.168.12.254 netmask 255.255.255.0 ifconfig vlan13 192.168.13.254 netmask 255.255.255.0 ifconfig vlan14 192.168.14.254 netmask 255.255.255.0 ifconfig vlan15 192.168.15.254 netmask 255.255.255.0 ifconfig vlan6 up ifconfig vlan7 up ifconfig vlan8 up ifconfig vlan9 up […]

Creating VLANs in DD-WRT (Part 1)

I’m breaking this post up into 3 parts because it does go on a bit. Part 1 – An overview of what I’m trying to do and creating VLANs on the router Part 2 – Configuring IP ranges and the router’s firewall Part 3 – Configuring VLANs on the SLM2008 switches Recently I have flashed my home router (a NetGear WNR3500L) with DD-WRT firmware and performed some basic and intermediate configuration to connect it to the internet and direct DNS queries for my lab domain to the correct DNS server. Now though I want to setup some VLANs. I want to be able to make use of some of the more advanced networking features in vSphere in my lab and this was one of the primary drivers for me selecting the router that I did. I already have two Cisco […]

Basic Router Setup

Previously I have written about the router that I have selected for my home lab / home network and how I flashed it to use DD-WRT. Having done that successfully I need to perform some basic (and intermediate) configuration to get it ready for use. Basic Setup Unless you have a completely plug and play broadband router you will have seen most of these settings before. They just look a little different here and I’m including them for context also. I won’t bother dealing with my broadband account details. First up then we look at the router’s basic network setup and DHCP options. Relatively straightforward but the important options are ticked by default: “Use DNSMasq for DHCP” and “Use DNSMasq for DNS”. Dynamic DNS If you don’t have a static broadband IP Address then setting this up could be useful. […]
