I'm using rsyslog 8.24 on debian. Each time I trigger logger "some message" the syslog refers to the same and only system user - it does not matter if I switch user (even as root), the messages are always logged as the same user - even on servers - I guess on a desktop, it's because the GUI is running as that user and on a server because I logged in as that user and later switch to root - could that be? But anyway, how could I log a message as root to the syslog?

  • It's my default system user I use to login to X11 or SSH on servers.

Because logger uses getlogin(3).



https://github.com/karelzak/util-linux/blob/master/misc-utils/logger.c#L379



static char const *xgetlogin(void)

 char const *cp;
 struct passwd *pw;

 if (!(cp = getlogin())


Which returns "name of the user logged in on the controlling terminal of the process". i.e. your system user.

            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...
