I have an ansible job that uses ssh to perform tasks on many servers. It uses an authorized key to gain entry. When I run the last command it just shows a long list of root logins from the ansible host.



root@myserver:/# last
root pts/1 ansiblehost.mydomain Tue Jan 2 7:00 - 7:00 (00:00) 
root pts/1 ansiblehost.mydomain Tue Jan 2 8:00 - 8:00 (00:00) 
root pts/1 ansiblehost.mydomain Tue Jan 2 9:00 - 9:00 (00:00) 
root pts/1 ansiblehost.mydomain Tue Jan 2 10:00 - 10:00 (00:00) 
root pts/1 ansiblehost.mydomain Tue Jan 2 11:00 - 11:00 (00:00)


I would like to suppress these entries from occurring because it fills up the screen and prevents me from investigating who has been logging in to the server.



Alternately, I would accept a way to set up my own logging of authentication for certain groups. For instance, if a user, who is in the admin group, logs in (ssh or terminal) it will make an entry in a log file /var/log/logins.log.

          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
