I have a server with firewallD on my home network.



My internet router sit at 192.168.1.1



My server external interface uses 192.168.1.70



My internal networks are 192.168.0.0/24 and 192.168.2.0/24 (this last one is offline right now)



The thing is, i was searching some ip-cameras that i was testing, and running fping i found some oddities in my network:



techmago@gw ~ $ fping -A -a -q -g -a -i 10 -r 0 192.168.0.0/16
192.168.0.1
192.168.0.254
192.168.1.1
192.168.1.70
192.168.2.1
192.168.8.34
192.168.60.5
192.168.60.9
192.168.60.7
192.168.60.11
192.168.150.1


The ips from network 8, 60 and 150 are outside my range and they even respond ping!
192.168.150.1 in special, seems to be a CISCO router...
Traceroute to these guys show they are outside my network.



This look like some odd role in my ISP side. To be extra-sure, i wanted to block in my firewall (firewalld) any incoming IP that are outside my range.



somehing in the likes of:



iptables -A INPUT --src 192.168.1.1/24 -j ACCEPT -i eth0
iptables -A INPUT --src 192.168.150.1/16 -j DROP -i eth0


How can i archive this? There is a better approach?

  • Since you are using firewalld. Look at using zones and the firewall-cmd command.

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...
