Hi there. I am working on a scheme to bypass the sentinel protection on an older bit of development software (16-bit) I use at both uni and home. Obviously if anybody else needs the dongle I can't work on my stuff so I want rid and they don't like me borrowing the dongle overnight (I like to work to the early hours and rise late in the day!!). I got the suggested software (WDASM and SoftICE) and read through Crackz tutorials and set to work. I have limited asm knowledge but I'm trying to improve that with the linked tutorals. I couldn't find the 7242 string any of the dll's so I set the old bpio 378 and waited. It broke in one of the main dll's several times but seemed to loop the same few addresses for most of them. I also found the DeviceIoControl string in one of the dll's and flaged that but that seemed to break just at desktop (maybe win98 testing port or something). So I gave up on that avenue. Now I'm at a juncture and could do with some advice. I thought getting IDA and applying the sig files to it may help (if that works for 16-bit files) if not I'm a bit stuck. When I load the file with symbol loader I get the message 'error no debug information available' and WDASM is a bit touchy if I try and adjust a bit of the code. Could you give me a few hints on how to continue.

yours sincerely

Hi I have reposted this in this forum because I acidentally posted it in the packers and unpackers forum. Since I wrote this I obtained a copy of IDA and ran the Sentinel Sig Files on the program but it didn't pick up any signiture functions. The program I am looking at is T*st-point with the program being available at the website of the same address (the upgrade is the full program). The offending dll is tpmain.dll but any further advice about avenues to investigate would be appreciated. Apparently it can be used with a cryptkey too but I know less about that than dongles ! Would this be an easier way to go?

Thanks again

Howdy,

Shame on you for posting the same topic again.

Peace, Woodmann

Yeah thanks Woodman,
I know I posted this previously on the other forum but as it was the wrong one I was hoping for a few more responses from people who would be more at my level (ie Newbies!). I did also ask a few additional questions on the end and honestly didn't want to waste anybodies time. If you could sugest some further means of isolating the offending code it would be appreciated.

Yours sincerely
