I need to find out process ID of a process which is running in a specific IP:Port



I have option to filter process using specific Port, but as my server having multiple IPs, so, And several process running with same port but with different IP. so, i need to find out the process which running with specific IP & Port.
Looking for hearing from you guys.

  • Is manual inspection good enough? I usually just look at the output of netstat -tulpn but that can probably also filter since yyou already know the IP and port.

  • lsof -t -n is another options for a manual list.

Will this be enough?



Say I am looking for a process listening on port 21 and IP of 192.168.168.2: 



#ss -l -p '( sport = :21 )' src 192.168.168.2

Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port 
tcp LISTEN 0 32 192.168.168.2:ftp *:* users:(("vsftpd",**pid=1444**,fd=3))e


Here -l looks for the Listening ports, -p forces to show PID.

            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...
