I installed Bind on CentOS7 and noticed that the DNSMasq which is already installed & running on the same port 53 where Bind runs. Looks like DNSMasq is default package comes up with CentOS.



Command - netstat -lnp|grep 53



I've few queries running in my mind -



  1. Is it a good idea to keep both packages which runs on same port 53, will it cause any issue?


  2. Is it ok to disable DNSMasq? if so, will it impact other functionlity? and how to permanently remove/disable DNSMasq?


Please can anyone provide some information on these tools, please



Thank you

          Only one service will be able to bind to port 53 at a time (on the same IP address)



          You should disable/uninstall DNSMasq if you want to run bind.



          You /etc/resolv.conf is probably set to localhost or 127.0.0.1, you will need to change this to point at an actual nameserver, or if you have bind configured to forward DNS queries then you can set /etc/resov.conf to the address bind is listening on.

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this
