How to manage users and passwords in LXC containers?

Example



  1. Container created (no matter if Ubuntu or Debian, the problem is the same) and running.

  2. New non-privileged user created inside the container (# useradd -m newUser -p newPass108).

  3. It is possible to switch the identity with $ sudo su newUser (Ubuntu) or # su newUser (Debian).

  4. The environment's behavior after that switch becomes very strange (it is not possible to use Bash as usually, loops don't work, completion doesn't work, command history doesn't work, etc.).

  5. It is not possible to log in as the new user via lxc-console.

  6. If I change the privileged user's password, it seems to work (change confirmed) but later it is not possible to use it, the default password persists.

Is there a special idea or workflow I need to stick to when managing the container? I would expect the container should work as a bit specific whole new machine.



I suspect I am missing something regarding the whole LXC idea.

          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...
