How is my ssh key unlocked without ssh-agent? And how do I fix that?

I have an SSH key that I use almost every day and I recently noticed that I haven't had to unlock it in a long while. I don't always shut down my computer and so it is fairly common that ssh-agent is already running when I access a server. But I've now confirmed that actually I'm never being asked for a password.



I feel a little bit like I've lost my mind, because ...




  • ps aux | grep agent doesn't show ssh-agent running.


  • ssh-keygen -y asks for a password but the password I expect doesn't work.


  • ssh user@example.com connects immediately.

There's nothing especially sensitive at stake right now, though that's temporary.



What should I be looking for here? How is my key working without a passphrase, even after a restart? I'm assuming I did something here, but how can I figure out what I did?



Per the comments, I did run echo $SSH_AUTH_SOCK and I see /run/user/1000/keyring/ssh -- lsof /run/user/1000/keyring/ssh isn't returning anything, though, so I don't know what is opening it.



How do I ensure that my key isn't just hanging out unlocked?




ssh ssh-agent

    There are other things which can act as an ssh agent. Do echo $SSH_AUTH_SOCK and you can see if you have one. An lsof on it will tell you what is providing it.

    no grep, just lsof. Though judging from the path, I suspect it's gnome-keyring-daemon.

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...
