Reset user password in Linux Bash on Windows 10

  1. edit file (in notepad or notepad++):
    %localappdata%\lxss\rootfs\etc\shadow
    
  2. find your normal user, for example:
    user1:$jsdjksadgfhsdf.saflsdf.sadf.safd:17299:0:99999:7:::
    
    and simply remove the hash part (below part)
    $jsdjksadgfhsdf.saflsdf.sadf.safd
    
    you will see a different hash - I hope :), so should look like:
    user1::17299:0:99999:7:::
    
  3. Save the file
  4. start bash again
  5. sudo bash
  6. password this will ask for your new password without requiring previous one.

Which linux version we have to do with?

Here is a memo to find it:

Check linux kernel version number

Open a shell prompt and type the following command to see your current Linux kernel version:

$ uname -a

Sample outputs:
Linux vivek-laptop 2.6.32-23-generic-pae #37-Ubuntu SMP Fri Jun 11 09:26:55 UTC 2010 i686 GNU/Linux
Where:
- 2.6.32-23 – Linux kernel version number
- pae – pae kernel type indicate that I’m accssing more than 4GB ram using 32 bit kernel.
- SMP – Kernel that supports multi core and multiple cpus.

/proc/version file

Type the following command to see Linux version info:

$ cat /proc/version

Sample outputs:
Linux version 3.2.0-0.bpo.1-amd64 (Debian 3.2.4-1~bpo60+1) (ben@decadent.org.uk) (gcc version 4.4.5 (Debian 4.4.5-8) ) #1 SMP Sat Feb 11 08:41:32 UTC 2012
The above output identifies the kernel version that is currently running.

Find Distribution Version

Type the following command:

$ cat /etc/*release

OR

$ lsb_release -a

Sample outputs:

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 10.04 LTS
Release: 10.04
Codename: lucid

Can you store password in Putty sessions?

The short answer is no. But you have a workaround that can help you to reach the same result: a one-click Putty shortcut to your server from your desktop.
That's the issue of this article.

Here is how to do:

  1. Create on the desktop a shortcut to Putty.exe
  2. Right click on the shortcut, select "properties" and edit the target attribute
  3. Change
    "C:\ProgramFiles\putty.exe"
    in
    "C:\ProgramFiles\putty.exe" root@207.150.12.233 -pw YourPassword
    where
    "C:\ProgramFiles\putty.exe" is the correct path of your putty.exe file
    "root" to the user you would use to login to your remote server
    "207.150.12.233" is the remote server IP
    "YourPassword" is the correct password.
  4. Click "Apply" then "OK" to commit the change.

Now simply double-click on your new shortcut and you'll be logged on your server.
