I set up an interface alias on my bond0 interface with this file



/etc/sysconfig/network-scripts/ifcfg-bond0:0


containing this



DEVICE=bond0:0
IPADDR=10.2.3.60
BOOTPROTO=static
ONBOOT=yes
NETMASK=255.255.255.0


and when I



$ ifup bond0:0


it comes up fine and I can ping it. However when I



$ ifdown bond0:0


it takes down both bond0 and bond0:0



This seems like a bug, but maybe I'm doing something wrong. How do I bring down bond0:0 without taking down bond0 with it?

          The method you're using of assigning an alias IP address bond0:0 is considered deprecated at this point with Linux kernels.



          IP-Aliasing:
          ============

          IP-aliases are an obsolete way to manage multiple IP-addresses/masks
          per interface. Newer tools such as iproute2 support multiple
          address/prefixes per interface, but aliases are still supported
          for backwards compatibility.

          An alias is formed by adding a colon and a string when running ifconfig.
          This string is usually numeric, but this is not a must.


          The correct syntax for deleting/downing an alias is to use ifconfig like so:



          $ ifconfig bond0:0 down


          I suspect you'd be able to do the same with iproute2's ip command as well:



          $ ip link set bond0:0 down

                    How many registers does an x86_64 CPU actually have?

                    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.
