How to manually supply passphrase to autossh, preferably on login

I want to run a bash script (as root) that among other things establishes reverse SSH tunnel using autossh. The SSH key has a passphrase.



  1. Ideally I would like to have to login as root in terminal and the passphrase would be retrieved from a keyring (the computer has Gnome), or something like this, and supplied to autossh (if needs be I can set SSH passphrase and the root password to be the same).


  2. If #1 is absolutely impossible I can do two things - (a) login and (b) run ssh-agent /bin/bash and then provide the passphrase ssh-add.


However even manual input of the passphrase as mentioned in #2 doesn't work.
If I run ssh-agent/ssh-add (as mentioned above), SSH itself works:
ssh -f -N -T -R 8888:localhost:22 -p 9999 tunnel@example.org
But:
autossh -M 7777 -f -N -T -R 8888:localhost:22 -p 9999 tunnel@example.org
doesn't work.



How can I troubleshoot #2 and then ideally implement also #1?

          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...
