A 404 error only for .aspx pages in Microsoft IIS
Pubblicato da Mic in Varie
So you can’t open an .aspx (or .asp) page in your new ISS on a Windows Server 2003?
Everything has ben set up fine but you’re not able to open those kind of pages?
Your ISS shows plain .html pages but not your new ASP.NET script, because it gives everytime a 404 page not found error?
But the page is there!

Internet Explorer 7? No! I want them all!
Pubblicato da Mic in Varie
Internet Explorer 7 has made a big step forward compared to his predecessor, with regard to security and standards support (think only the transparency of PNG and CSS, although, unfortunately, not entirely).
The golden rule of any good web developer is to test the site with various browsers in order to verify the different behavior, because not the standards are not so standard indeed (!!).

How to find, recover or reset Windows passwords
Pubblicato da giuliastro in Varie
Sometimes it happens to remember one thing for years and suddenly forget it. Before writing this article I asked myself what I would do if my mind completely erased my Windows 2003 administrator password and I did not have any rescue disk to get back into my system.
As a first method I would certainly try to use Ophcrack. It comes with a Live CD, contains rainbow tables with the hash of all passwords and allows to find windows system passwords without causing any damage to the server. It doesn’t use brute force algorithms but direct verification of hashes, this means that if you can find passwords through rainbow tables it is just a matter of a few minutes. You just need to download the live CD, burn it, boot it and run the tool.
As a second attempt I would try a service such as Login Recovery. I don’t know exactly how it works, but it probably uses the same techniques as Ophcrack (I don’t think there are too many: brute force, reset or direct comparison of hash). The system provides a Live CD or floppy that extracts the files with passwords from your computer and, as a second step, it uploads them to the Login Recovery website. The free service allows to get results in 48 hours, while using the paid service (a few euros anyway) you can get results instantly. On the web site they say that this system is able to find an administrator password for Windows 2003 computers and ensure to get refunded if the method does not work. No theoretical damage to the server either.
Another attempt I could do is using a tool such as Windows Key. This program lets you create a Live CD or floppy and allows you to reset passwords for all users on your machine. The program should also support Windows Server 2003. In general, however, the tools and services to reset the password for Windows are so many and all theoretically painless. Note that not all of them recover passwords, some of them simply reset (blank) them. One method that I have personally tested some time ago on an XP machine is described here.
It should also work with Windows 2003, reset the password and allows you to change some policies by simply using a CD or floppy.
In all cases, however, you must reboot the machine (and boot from a CD or floppy) and you need to consider the fact that the file you want to read could be encrypted and it could be somewhat more complicated to see SCSI or SATA disks on boot. But this issue can be certainly solved by using appropriate drivers.

Alla fine Linux la vince
Pubblicato da Mic in Linux
Qualche mese fa avevo scritto un post in cui, tenendo una posizione chiaramente estremizzata, cercavo di analizzare, visto il flop di Vista, la situazione in cui si viene a trovare chi voglia acquistare un computer nuovo.
In questi giorni ho affrontato un problema simile e sono arrivato ad una soluzione che mi ha veramente stupito. Continua »

Ubuntu 8.04 contro Windows XP SP3: chi e’ piu’ veloce?
Pubblicato da giuliastro in Linux
Inutile dirlo, chi parteggia per il Software Libero vede in Linux il condottiero con cui sconfiggere l’astuto e ricco Windows, rappresentante più caratteristico dei sistemi operativi commerciali.
Chi difende quindi a spada tratta Linux è convinto che il proprio sistema sia in assoluto il migliore. Forse un pò più complesso da usare ma sicuramente più leggero, versatile e performante dei concorrenti. Ma come stanno realmente i fatti?

Mohammed Saleh ha cercato di fare un confronto tra l’ultima versione di una delle distribuzioni più popolari, la Ubuntu 8.04 “Hardy Heron”, e Windows XP, da poco aggiornato con il terzo Service Pack, utilizzando come banco di prova applicazioni identiche disponibili per entrambi i sistemi operativi.
Dalle analisi possiamo sicuramente dire che Ubuntu sembra più performante di XP con applicazioni che fanno un uso intensivo del disco fisso (probabilmente grazie all’ext3) e nel multi-tasking, mentre il sistema Open Source sembra soccombere quando si tratta di operazioni che coinvolgono il multimedia in genere, grazie alla maggiore qualita’ dei driver di Windows. Per quanto mi riguarda, comunque, una delle cose che mi ha sicuramente stupito di più è la significativa differenza tra i due sistemi in tutti i test.
