Upgrading the CPU on a Dell GX240 – Again!

I never expected that I would upgrade one of my elderly Dell GX240 PCs again, but today I did. I have two GX240 tower PCs. One of them has been used as a firewall for five years, the other as it’s fallback spare. I retired both of them a few weeks ago, replacing them with […]

D-Link DFE-570TX and Broadcom BCM5821

I have just acquired a used 4-port D-Link fast ethernet PCI board from a seller on eBay. I have been looking for one of these for my ‘new’ firewall for ages and was about to give up. The firewall is an old crate of a Dell GX240 with PCI slots but it still has plenty […]

FOXSAT-HDR Dropbear SSH with keys

WARNING: This article relates to the dropbear package version 2012.55 and not the updated package 2012.55-1 that now includes the ability to login with keys. It is no longer necessary to use these instructions to modify the dropbear installation on your FOXSAT-HDR. The instructions on how to generate and distribute client keys are still valid. […]

Custom firmware for Humax FOXSAT-HDR

I have been using my Humax FOXSAT-HDR since I bought it new in 2009 and functionally it hasn’t changed much bar the addition of BBC and ITV catch-up TV services. I have always hoped that the manufacturer would issue a DLNA server upgrade to the firmware, but it never came. That is until today… While […]

Unable to enumerate USB device on port…

I have an old PC with what appears to be a broken implementation of USB. I cannot obtain a BIOS update and there is no BIOS setting to switch off USB either. Very old Linux distributions would run on this PC, but only on those with USB support as loadable modules. For later kernels with […]

What to do with an OldWorld Mac?

During our recent house move I found my old and dusty PowerMac 8500/180 while we were packing up the contents of my garage. It had been placed on the bottom shelf of my car spares shelving for a time when I could either make a VGA adapter cable or acquire another old Mac monitor to […]

Find BIOS version using Ubuntu

I found this really simple way of finding the installed BIOS version on an Ubuntu PC without having to reboot. Simply execute the following command in a terminal session and scroll through the output until you find the BIOS section. sudo dmidecode -s bios-version For more system information, just scroll through the output until you […]

Camrivox Flexor 500 SIP Telephone

I recently purchased three Flexor 500 telephones to use with my new FreeSwitch installation at home. So far, I am quite pleased with the telephones although I am still in a process of discovering their capabilities. It appears that these phones are popular with VoIP providers that sell service to end users with a preconfigured […]

Acer DX900 Smartphone

I bought an Acer DX900 Smartphone last September without actually trying one out first. That was a big mistake. The phone’s specification is impressive but it’s the dual SIM card capability that I really needed. I had a look at some Samsung Duos models and they were very good, but none of them at that […]

Monitoring a Linksys WAG200G using SNMP

I have been using a Linksys WAG200G as a wireless access point since December 2007. I’m not using it for my broadband connection as I have a separate firewall and router already on my network. It has been running reliably without any problems since installed and it occurred to me that it had been some […]
