I own a dell laptop configured with Win-10 Home Edition. For some project, I had to live boot Lubuntu v17.10.1 on it.



The issue is - while trying to get access to 'su account' I am unable to bypass it. It asks for a password, which I have no clue where to find.



I tried using the command - passwd Lubuntu, but it changed password of something else, and not 'su'.



Can someone please guide me how can I obtain password of 'su'? It's important for me to obtain admin rights.



Looking forward to some quick advice and assistance from experts here.



TIA.




su lubuntu

  • In this case, use sudo passwd to set the root password if you really need to, but you should execute most commands that need superuser privilege with sudo.

  • thanks @WeijunZhou, it worked. :) Also, will this technique of putting 'sudo' work for every command?

  • Not really by literally putting it before every command. You need to do a little bit work if you have redirections, but generally you can always achieve the goal with sudo without explicitly invoking su. If you need something similar to su, you can just do sudo -i.

Ubuntu assumes that the user should use sudo instead of su by default in their live images as well as their default installation. You can use sudo to do most tasks that can be done by su, but if you really need to change the superuser password, you can do



sudo passwd


This will prompt you for the new superuser password and you can set it. You can then use su as usual.



Alternatively, you can obtain a login shell by sudo -i, or a shell by sudo -s. Both of which give you a shell with superuser privilege. As for the difference between -i and -s, check the manpages.

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...
