USB-Ethernet for MiniX media player

Back in September I purchased a MiniX clone from DealExtreme. The device appears functional, and pre-rooted for convenient access via ADB. However, WiFi connectivity was…. pathetic. In the past few days I’ve received two cheap USB-Ethernet adapters from DealExtreme that solved my network connectivity problems. One is based on DM96xx chipset, the other on an […]

Adding OpenWRT to TP-Link WR703N

Using PPPoE from a FreeBSD 6.0 server to access iiNet

I’ve had broadband access with iiNet since January 2006, using their recommended Belkin 4-port ADSL router + VoIP adaptor (F1PI241ENau). The Belkin box NAT’d traffic between my home LAN and a PPPoE connection to iiNet while also providing VoIP ATA functionality to my home Asterisk server. In August 2007 I migrated the PPPoE termination, firewalling […]

This month I had to install FreeBSD 5.3 on a laptop that lacked a bootable CDROM (a Toshiba Portege R100). Rather than launch the installation from floppies, I decided to explore the use of pxeboot (supported by the R100’s BIOS) to enable the laptop to boot the FreeBSD 5.3 Installation CDROM over my local LAN.
