The price finally comes down to a somewhat reasonable level for HDMI cables and now they don’t want to sell them anymore. What about small devices that incorporate hdmi such as phones?

If you’re running an older distribution of Linux or you just find that the kernel module is unavailable because your RealTek RTL series PCI-Express Ethernet card is just too new, then you’ll need to install the driver manually.

The Category 5e standard guarantees performance of attenuation, return loss, propagation delay, delay skew, NEXT, Power-sum NEXT, ACR, power-sum ACR, ELFEXT, and power-sum ELFEXT to a nominal range of values at 100 MHz. The Category 6 standard guarantees to 250mhz. Cat6 is more expensive and doesn’t get you any improvement right now unless you’re running 10Gbase-T hardware. Cat5e are easy to make. Just get a spool, a crimper tool, and some rj45 jacks. If money isn’t a factor, run cat6 or fiber, and run multiple cables at a time. Get fancy punch down terminals and build a wiring closet with fancy lighting. And pay a high end home theater company to do it all for you.

TUN is for IP tunneling. TAP is for Ethernet tunneling. Check out vtun if you’re looking to get networking working in qemu or kvm for virtual tunnels over tcp/ip networks with traffic shaping, compression, and encryption. vtun also supports serial and pipe tunnels.

My new mobo has two gigE ports, so I figure why not trunk them together to work as one network device? This will work great for a Linux based network storage device (NAS). This will create a virtual interface named bond0 with the external ip address of 192.168.1.100. Anything else on my network will see this computer with this address. It doesn’t matter which interface is actually plugged in, one, the other, or both. As long as one is plugged in it will continue to function.
