gdb question

[Brandito]

Hey... I have been testing my reverse engineering skills out.
I am running into a problem when the symbol table is "strip -s".

My question is this... I am using gdb and I'd like to do a BREAK
when ever I feel like it. I don't want to have to preset my break points.... I want to
hit a hot key or something. Is this possible with gdb?

What is the best way to single out certain functions when there is no symbol table?

Thanks!

PS: yes... I want to use gdb. I am not paying for IDA Pro.

If it is interactive, what happens when you press control-c?

Other things you can experiment with include signals and use of kill to send various signals to the PID that is running. One or more may help you to "break" to gdb (interrupt to cause your application to drop back to gdb) so you can play.

Thanks for the Ctl+c... I've done that before but I've always started it from the begining when I ran it again. I chose 'n' and it put me back where I left off. Good to know... thanks.
