I have run the following command using ss.



# ss -ua | grep radius
UNCONN 0 0 :::radius :::*


My question is, what interface/IP does :::radius corespond with? What Interface does :::* correspond with and where is its source port information for that matter? What do the asterisks mean in the output of ss? Do they mean the same as 0.0.0.0?

  • :: is the IPv6 equivalent of 0.0.0.0, that is, "any address". (Actually ss uses * for IPv4 any address.) :* means "any port", both in IPv4 and IPv6. :radius means :1812, from /etc/services. The output of the command means that some process is listening on all configured address UDPv6 port 1812 accepting datagrams from anywhere any port.

            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...
