The following is a short but useful script which allows your system note to output recent info regarding router health and/or other details you might be interested in.

Study guide: Moving up to RouterOS v6

Given v6.0 stable is now upon us I’ve taken some time to collate some of the posts I’ve been familiarising myself with over the last few weeks to understand the major changes that have been implemented in this release and how to best upgrade and make use of these.

Apple USB Ethernet Adaptor + RouterOS = Success

I’ve been wanting to pickup one of the Apple USB to Ethernet adapters for a while now, and as well as trying it with a bunch of mobile devices I had a change to plug it in and give it a try with my RB751G.

As you can see the device is detected instantly (Tested with v5.4 so I assume it will work with anything onwards) and no reboot is required for the ethernet adaptor to appear and function! It was loaded just seconds after I plugged it in:

I imagine you could use multiple devices if you had a hub however given the speed limit of USB 2.0 (480Mbps) you would be limited to how many you could attach and still get full throughput. The adapter is 10/100BASE-T so no gigabit here.

Just for the sake of it I ran some btests between my RB1100AHX2 and the RB751G-2HnD with the Apple Ethernet Adaptor. Could easily achieve 100Mbps half duplex when testing from the RB1100AHX2 for traffic generation however trying to do a full duplex test was maxing out the CPU on the RB751 so I would get around 150~Mbps of throughput.

The max MTU size for the adaptor is 1518, this is not listed anywhere that I could find but was determined through simple trial and error.

Side note: If you’re looking for Windows 7 drivers to test this out on a PC; I found the recommendations and files at this site worked perfectly.

Back from cracked camp.

Just a quick apology to those I’ve been slow to get back to or had to turn away over the last couple of weeks.
I’m finally back to being able to use 2 hands for typing now so should be getting back into the swing of things!

Please feel free to email me at [email protected] and I’ll be going through some of the older emails as quick as I can.

For those who weren’t aware, I’ve been down and out for the last 2 months due to a particularly nasty broken arm, caused by a lack of vitamin D (the one you get from sunlight, doh!).

RouterOS as a PXE (Net Boot) server

As more and more people switch to netbooks; the ability to provision Operating Systems and boot iso’s over the network becomes highly useful. It has become quite common to see CD/DVD ROM drives removed altogether in mobile and even some desktop machines.

Installing and booting machines using RouterOS as the bootp/tftp server is quite a simple process if you are familiar with PXE booting, but for those of you who are not, allow me to provide a basic guide along with a preset package for you to try this out yourself.
