Synology Folder Compression

I had a desire to enable compression after the fact on some shares. Synology (As of DSM 6.0) doesn’t have the facility to modify the compression settings of a folder after the initial creation – and perusing the forum, it seems you can’t enable compression at all on the /homes location.

Much discussion orbits the topic of chattr, how it isn’t installed and how to go about installing it. I have a way to do it without installing anything! btrfs-progs is already installed 😀

SSH into the device, and issue the command (as root)

btrfs property set /volume1/homes compression lzo

The btrfs command gives you plenty of other options to explore – perhaps best as a non-root user. Now to find a built-in for disabling Copy of Write.

GNU Screen and Xmodem!

How many terms are incompatible with Google? screen (the gnu screen program) is one of them unfortunately.

How often have you found yourself needing to upload an IOS to a dead router or switch? And how often do you have to do this on a Linux or Mac based machine?

Well, here is how to use sx from the lrzsz package and gnu screen. Firstly, connect your console to screen with a command like so:

screen /dev/tty.usbserial 115200

Then begin your xmodem transfer and follow up with some fancy screen commanding

^a :exec !! sx -kb Downloads/newfirmware.bin

That is control-a and then type, without the quotes, “:exec !! sx -kb path/to/firmware.bin”

Genius! Unfortunately, sx doesn’t really come stock with my particular flavor of OS so some package manager digging was in order.

Hacking Securom with UNIX

I found myself in a situation: Securom error 1000. Or, “we don’t like you because you don’t fit our corporate model of the ideal consumer.”

Disclaimer: This is a lesson in overcoming corrupt read-only media.

I wanted to install a piece of software that didn’t like my particular set of software installed. More specifically, I was having trouble installing Oblivion GOTY because the Securom protection doesn’t like that I run Windows virtually within OSX with Parallels. Or maybe it’s the disc emulator software installation. However the case, this post is how I circumvented that difficulty using UNIX WIZARDRY and a patched setup file. Users win every time.

Cisco Password Recovery

So you have a cisco device that is password protected, perhaps it is a mission critical core device and you lost the password. It doesn’t matter why, but maybe when you recover it, take note of it this time.

So what I present here is a method for actually recovering the MD5 hashed “Enable” or user passwords through a dictionary attack (and physical access). Continue reading

Vista

Alright… I did it. I put the Vista disc in and did the install thing. It took a long time. The first thing I noticed: Nothing. No choices! No customization other than timezone. There wasn’t any obvious click here to fix buttons. Yes, I am alluding to the fact that Vista is broken upon installation.

Okay, I’m extremely critical and biased… but I’ll try to be fair.

Linux Story

Windows is a Pile of Crap

First, it doesn’t install right — It wrote over my boot loader with some crap-encrusted near-sighted Windows-Only thing. It’s useless, how do I access Linux with this? So I needed to boot with a forensic Linux disk and reconstruct a less-than-useless bootloader: Grub

There goes about half an hour. Continue reading
