help with reverse engineering (using gdb)

[boast]

My goal is to set a breakpoint where a string is accessed in memory.

I did
strings -ao -t x bin_file and I found the string I was looking for, and it was at (I assume it is a relative address offset) 0x2ae59.

But when I run the application in gdb, the addresses seem to be direct, like 0x7fff84fcd2a4.

How do I go about setting an awatch for that ASCII string? I could not find how to search for strings within gdb.

thanks.

You can find details of where segments load with cat /proc/<pid>/maps

I don't know enough about this to say much more.
