reverse-engineering

问题 I recently bought chinesse device that connects via bluetooth with android phone / tablet. Since there is no application availible for windows / linux I want to create one for personal usage. Usually phone connects to the device and exchanges some data. I connected PC to the device and looked into serial debugger and menaged to discover the protocol (one way only). Phone sends only one command to the device. But this time I'm not able to find out what it containts. Is there any software that

问题 How do I get a list of all index & index columns in SQL Server 2005+? The closest I could get is: select s.name, t.name, i.name, c.name from sys.tables t inner join sys.schemas s on t.schema_id = s.schema_id inner join sys.indexes i on i.object_id = t.object_id inner join sys.index_columns ic on ic.object_id = t.object_id inner join sys.columns c on c.object_id = t.object_id and ic.column_id = c.column_id where i.index_id > 0 and i.type in (1, 2) -- clustered & nonclustered only and i.is

问题 I've Joomla 1.7 and lots of component in it. I'd like to make a "reverse-engineering" of the install of a component. I've edited most part of it and i'd like to repack this to install in a new fresh Joomla installation. Any idea? thanks! 回答1: It's fairly straight forward - you download all the related files then zip them up with a new XML manifest. Of course you have to make sure that you get all of the files because they can be located in a couple different places. Luckily, the Joomla

问题 I'm SSHd into a remote server with some binary challenges. At one point it asks for me to input text. I know it's using fgets() to read stdin , and that I can overflow where it is being copied to and overwrite a nearby variable. The problem is I don't know how to type the address values I need, \x84 and \x04 etc. If I were able to use bash I would echo -ne "\x84" or use a C hex array but I can't do that kind of thing here. I've tried using a hex to ASCII converter and copying the binary

问题 I am hoping you guys could help me understand how relocation entries and ELF section data are related, and how it is all processed and generated. I have an ancient unsupported tool that takes an ELF file and a related PLF file (partially linked file, generated earlier in the build process) and builds a custom relocatable file from it that is used on a platform (PPC) with tight memory constraints. This works fine except that it contains about a meg of initialization code that we want to unload

问题 this is the assembly code i am supposed to translate: f1: subl $97, %edi xorl %eax, %eax cmpb $25, %dil setbe %al ret heres the c code I wrote that I think is equivalent. int f1(int y){ int x = y-97; int i = 0; if(x<=25){ x = i; } return x; } and heres what I get from compiling the C code. _f1: ## @f1 .cfi_startproc %bb.0: pushq %rbp .cfi_def_cfa_offset 16 .cfi_offset %rbp, -16 movq %rsp, %rbp .cfi_def_cfa_register %rbp ## kill: def %edi killed %edi def %rdi leal -97(%rdi), %ecx xorl %eax,

问题 How do I add custom menu items to the context menu for files in Finder? Unfortunately, most of the information out on the Internet and on Stack Overflow doesn't work in 10.6 or are too limited. Automator, for example, doesn't allow you to create items dynamically or create submenus. I know it's still possible to do this sort of thing because Dropbox and FolderGlance both do similar things. Does anyone know how they implemented this? Thanks. 回答1: I downloaded FolderGlance and it appears to use

问题 I am looking out for a eclipse plugin or an open source tool to reverse engineer the sequence diagrams. I tried using Alto UML, but it just gives out sequence diagram of the class chose. I would like to have a sequence diagram of the whole call stack with methods, input arguments and output arugments as well. Could you please let me know some pointers on this? Thanks! 回答1: Take a look at the MoDisco open source eclipse project MoDisco 回答2: Architexa does have sequence diagrams for the whole

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 12 months ago . IDA can do this:some function with no symbol will named with 'sub_address'. How can I do this at runtime. enter image description here 回答1: How to extract all functions out of a compiled elf file,even the function has no symbol You don't define what is a function for you (and you really should).
