SSH from local to intermediate host to final

I am using a jump server to connect to a final host with this command:



ssh -t intermediate ssh final


but I want it to work with a normal ssh or scp command, so I have tried to setup the config in .ssh/config:



Host final
 ProxyCommand ssh -o 'ForwardAgent yes' intermediate 'ssh-add && nc %h %p'


this works, but there is one big dilemma. Intermediate's security policy requires me to password protect .ssh/id_rsa. When I add a password to it I can no longer use the command, as it does not ask me for a password, but rather assume it is empty.



  • I have to authenticate to intermediate using a password (key not possible)

  • intermediate has to authenticate to final using the keyfile

          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...
