- o Minor features:
- - If set to 1, Tor will attempt to prevent basic debugging attachment
- attempts by other processes. It has no impact for users who wish to
- attach if they have CAP_SYS_PTRACE or if they are root. We believe that
- this feature works on modern Gnu/Linux distributions, and that it may
- also work on *BSD systems (untested). Some modern Gnu/Linux systems such
- as Ubuntu have the kernel.yama.ptrace_scope sysctl and by default enable
- it as an attempt to limit the PTRACE scope for all user processes by
- default. This feature will attempt to limit the PTRACE scope for Tor
- specifically - it will not attempt to alter the system wide ptrace scope
- as it may not even exist. If you wish to attach to Tor with a debugger
- such as gdb or strace you will want to set this to 0 for the duration of
- your debugging. Normal users should leave it on. (Default: 1)
