I have an old application I'm trying to run on CentOS6 that uses a couple machines: abc1 and abc2.



I log into abc1 and run the application, which ssh's to abc2, changes the DISPLAY variable to abc1:0.0 and runs a process that tries to open a new window on abc1. However, it fails with: cannot open display



If I just do an ssh -X abc2 or ssh -Y abc2, I can open an xterm with no issue, but the DISPLAY variable is set to something like localhost:10.0



Note that abc1 resolves correctly (I can ping abc1 from abc2)



I cannot modify the application at all, so don't have control over the DISPLAY variable it's using. However, I can modify the configuration of both abc1 and abc2. I'm on an isolated network and do not care about security.



Is there something in ssh config or something else that I can change to allow abc1:0.0 to work?

          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...
