-T option  --  trace system calls
              ==  -T[xsdt]*

If specified, signals occurred in DeleGate processes will be watched by the parent DeleGate using "ptrace(2)" then recorded into TRACELOG. If -Tx is specified, DeleGate process which is going to execute "execve(2)" system call will be trapped and killed. This will be useful for security enhancement preventing any unexpected execve() which can be the method of intruders. This -T option automatically turn on -S option to immediately respond to events occurred in children, but you can turn off it by adding "s" flag like "-Ts". Adding "d" flag like "-Txd" will make logging detailed, while adding "t" flag like "-Txt" will make logging terse.
