When migrating some VM from vmware to HyperV, I noticed some strange behaviors that were confirmed by running the bginfo tool: some network adapters were hidden in the background, waiting to cause some weird errors someday (especially because of the MAC address cloning...) Therefore, I found some articles to clean up […]

In order to test some trial software under good conditions -- that is, not a race against the clock, I wanted to isolate an HyperV virtual machine. This is in no way to promote piracy or something, just peace of mind. I'll eventually buy the software. This being said, here is how I did: Forbid internet access to the […]

This is an update of the original article Setup OpenVPN Server on Linksys WRT54G with DD-WRT. Have a look for the certificates generation (easy rsa stuff). I recently bought an Asus RT-N16 router with VPN capabilities. However it turned out that the included VPN was not as slick as I wanted to. Most builds of DD-WRT […]

Since the same issue occurred on various occasions, I will summarize it here. It is quite common for applications to create user accounts to run services under. This happens for SQL Server, HyperV, and a bunch of other software. However the service may refuse to start with a "log on as a service" permission is missing. […]

I flashed a wrong dd-wrt firmware on my WHR-HP-G300N -- I flashed WHR-G300N instead. Notice the two missing letters... Nothing prevented me to flash this image, but after reboot I only got a solid red led (DIAG). Trouble! It's been quite "fun" to bring it back to life. Following several guides I was poking in the dark, […]

I acquired a Netgear ReadyNAS, not a very powerful one but quite unexpensive and good hack potential, as it is based on Debian on ARM. The OS version is ReadyNAS 6.1.8 at the time of writing. After installing Transmission (through an app) and OpenVPN (through apt-get) quite easily, I wanted to route Transmission […]

More a shameless copy/paste compilation of some articles (in case they vanish from the internet) Low Rent Firmware Hacking Quick'n Dirty Firmware Reversing Some tips Tip 00x01 - I normally like to look for bootcode if I have the choice. If not, I just deal with what I have. Tip 00x02 - Firmware files are in hex and […]

Expand a logical volume Source Make sure the host partition is big enough (using parted or gparted) (must be done offline if partition is mounted) The following commands can be done online (even if the logical volume is in use) Check disk usage (Allocated / Free) sudo lvm vgdisplay Check allocation of the lv sudo lvs […]

DriveSort sorts the directory tables of a volume formated in FAT12/FAT16/FAT32. This sort orders the files in each folder according to their short or long names alphabetic order. The majority of recent operating systems sort the files before showing them to the user, either by name, by size or by whatever the user […]

Also known as ZuniDigital ZR301, and maybe others too. Based on Realtek 8196C (SoC) + RTL8192CE (WLAN) + MXIC 25L3206E (4MB of flash) + Winbond W9825G6 JB-6 (32MB of RAM) But no success, it appears that 8196C is based on "broken" Lexra MIPS Microarchitecture. Not sure if it will ever get good support. On top of that […]

In an attempt to secure my internet connection, I setup OpenVPN on a OpentWRT enabled router: a good old Linksys WRT54G v3.1. The best firmware for this router seems to be OpenWRT Backfire 10.03.1 (brcm-2.4) (LuCI 0.10.0) (also in attachment of this page). The upgrade is very easy from the Linksys or (DD-WRT) web GUI […]
