Filed under
HowTos

Imagine you have a machine with all of his disk full and another with unused Gigabits, and you don't want to move the data from one to other. Why not using the second's disk on the first, you can do it with iSCSI but you can do it with ATA over Ethernet (AoE) too. It's the second method I'll explain is this article.

All of this was made with two computer running Debian Etch.

Prepare the kernel

First check if your running kernel have AoE, the config option name is CONFIG_AT_OVER_ETH, have a look at fig1, my kernel has AoE in module

fig1
host:/# grep ATA_OVER /boot/config-`uname -r`
CONFIG_ATA_OVER_ETH=m
host:/#

If not, configure your kernel and activate AoE in core or in module like you prefer

LG's got a flip phone that runs Android Lollipop

Flip phones aren't just for retro hipsters and the elderly anymore... well, actually they kind of are. But they're super popular in Asia, and now you can get one that'll run the latest apps: LG's Gentle flip phone. The faux-leather adorned device is running a bleeding edge version of Android 5.1 Lollipop and packing 4G LTE. Otherwise, it's not exactly a power-user's dream with a 3.2-inch 480 x 320 screen, 3-megapixel rear camera, 4GB of (expandable) storage and 1GB of RAM. But for just 20 million won ($175) it would make a fine second phone, provided you live in Korea -- it's unlikely to come here, and similar flip phones can be pricey to import. Read more
