After running a (probably broken) openvpn script, I have an IP route table where one entry is a URL:



# netstat -r 
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
default 10.0.0.1 0.0.0.0 UG 0 0 0 wlp58s0
10.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 wlp58s0
google.com 10.0.0.1 255.255.255.255 UGH 0 0 0 wlp58s0


How can I delete this last row? The regular way throws an error:



# ip route del google.com
Error: any valid prefix is expected rather than "google.com".


I'm on gentoo linux, if that matters.

    Adding the -n flag to netstat will remove any confusion.

The entry google.com is not a URL; it's a domain name, or possibly a host name. (It could be part of a URL, though.)



If you use netstat -rn you will get IP addresses instead of names in that first column. From there you can delete the route - again by reference to its network and subnet addressing.



netstat -r
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
default server.roaima 0.0.0.0 UG 0 0 0 eth1
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
google.com 0.0.0.0 255.255.255.255 UH 0 0 0 eth1

netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
0.0.0.0 192.168.2.2 0.0.0.0 UG 0 0 0 eth1
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
216.58.198.174 0.0.0.0 255.255.255.255 UH 0 0 0 eth1

route delete -host 216.58.198.174


You can also do this with the newer ip route, which lists routes only with IP addresses. Use ip route del to delete the unwanted entry.

            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.
