I have an A record in the DNS server which points to my server IP. Noted that I have multiple domain names which points to the same server too.



Now I need to know, which IPs send a request to this specific domain name? pbx.mywebsite.com



How can I figure it out?




linux centos dns ip

  • can you explain the context to which this applies (web service, ssh, ... ?)

  • @tonioc Not sure what you mean exactly, but it's all about a website, so I guess the answer is web service.

You can monitor the requests at several points of your infra-structure.



If your intentions are knowing who made the DNS requests, you can configure and activate BIND logs temporarily to log queries requests. At the BIND server, you can also run dnscap or tcpdump



If you want to know who accessed the site, you can see the web server request logs, or use tcpdump at the web server side.



In BIND to activate query logs, the syntax is:



logging 

 channel querylog
 file "/var/log/querylog";
 severity debug 10;
 print-category yes;
 print-time yes;
 print-severity yes;
 ;
 category queries querylog;; 
 ;
};

  • If you run your own DNS/BIND server for that domain, you include it inside the options section for it to log all the queries done in a file, and then you grep it for your queries. Otherwise, ignore it.

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...
