From NAS-Central Buffalo - The Linkstation Wiki
I'm newbie to LinkStation community
As of Easter holidays I started to play a bit with my HS-D400GL. First hacking thing I tried was to flash OpenLink 0.51b using the guide on this Wiki.
I ignored the complaint about downgrading from 1.49 to 1.46 assuming this to be unavoidable. Maybe I should have asked first. I'm not sure about what went wrong, but now the only working bit is passive DHCP and ftp (Port 21) which I can't seem to log into using root, empty password or anonymous account.
Used Nmap to check that system is assumed to be some Linux 2.4.18 to 2.4.32, the box renamed to HD-HGLAN-EM.
Now I'm looking for any idea about what to do from now on. Seems I have to disassemble to extract the HDD.
