• Execution step by step using ptrace_singlestep() or hardware interruption 3
• Can use distorm disassembler
• Dump registers, memory mappings, stack, etc.
• Syscall tracer and parser (strace.py command)

Status

Some important features are missing:

• Symbols: it's not possible to break on a function or read a variable value
• No C language support: debugger shows assembler code, not your C (C++ or other language) code!
• No thread support

python-ptrace works on:

• Linux version 2.6.20 on i386, x86_64 and PPC32 (may works on Linux 2.4.x and 2.6.x)
• FreeBSD version 6.2 and 7.0 on i386 (may works on FreeBSD 5.x)
