I just got an alix apu.1c4 in the mail. It is a great board for ~200Euro with a great set of features, you can find more on it here. First step is to pick up the BIOS-Update here. Then unpack the file: tar xjvf apu_tinycore.tar.bz2 Now we have to create a FAT filesystems on our flashdrive, in my case: /dev/sdc. mkfs.fat -I /dev/sdc Then mount the filesystem and copy the files to the flashdrive: ...

Quite a while ago I got to toy around with some ubiquiti UAP Pros, awesome, cheap, performant WiFi Access Points. As I missed the last train home from my hackerspace I began to toy around, always on the hunt for a little exploit. Webinterface Exploits(XSS, SQL Injections or what so ever) were easily found, but that’s not what I was looking for. Everyone can do that. The goal was to find something nobody has done before.

First off we need to modify the sourcecode of /usr/src/sys/dev/ixgbe/ixgbe.c as follows: static int allow_unsupported_sfp = TRUE; And then we need to recompile the kernel module: cd /usr/src/sys/modules/ixgbe && make install and then reboot our system. If everything goes well the interface will show up somewhat like this when executing ifconfig: ...

After assembling the PCIe card I was luckily surprised that my kernel brought up the NIC without any difficultys, so I plugged my SFP+ modules into the server, only to be greeted with: ixgbe 0000:24:00.1: failed to load because an unsupported SFP+ module type was detected. ixgbe 0000:24:00.1: Reload the driver after installing a supported module. Yay. After 2 hours of useless googleing I asked a friend who happens to be a linux kernel maintainer, and luckily he knew just the fix therefore: ...
