anyone know of a good C decompiler? A good disassembler would be nice too

objdump or ndisasm for the dissassembler, i used to have a c decompiler but i can remember what it was called, what do you want it for?

I'm sorry to interrupt but what is a decompiler supposed to do?
It won't give you a C source code out of an asm-File, thats for sure...

thats what it attempts to do, it obviously cant rescue variable names/comments but it can look at the stack frame and determine what types the local variables are, reconstruct function calls, etc but you dont get a nice looking source file back at the end, its just a bit easier to read than the assembly

IDA Pro http://www.datarescue.com is the best disassembler around. It's pricey and win32 only. A freeware version (that runs under wine) can be downloaded @ http://www.simtel.net/pub/pd/29498.html . Also check http://www.2good.com/software/idastuff/ for a couple of utils to create .pat files out of elf objects for use with FLIRT.
