Lost PSWD - How to recover

[Zadikim Yisrael]

List Users,

During the setup of  the Linux server, I was testing a lot, to make sure the server worked well for all windows clients.
The school needed a server.  I choose Samba.  In the process I forgot the pswd.  How to retrieve pswd?

tnx

Do you mean the root password? You cannot "recover" it, you will have to
set a new one.

Boot into the sigle user mode, type "passwd" and set a new password. If
GRUB is protected by a password, you will need it, too. If you do not
know it, you will have to boot from an extern medium (CD, USB, ...),
mount the hard drive with the root file system and edit /etc/shadow.
There you can replace the crypted password for root with nothing,
effectivly allowing the root to login without password.

If you can boot from a fedora rescue disk, you can mount the system in
rescue mode, chroot into /mnt/sysimage and use passwd to change root's
password.

I do apologize for not responding quickly.  Fedora Core user pswd is the problem.  They (school) needed to pass large files between admin and instructor.  When my testing was complete, and everything was working, including NX (remote desktop), I wast called to another job.

I will perform the suggestions below.

Thank you,

strange that school would ask someone to set up a server and said person
doing so, is not familiar with basic commands, especially "man", "info",
"sudo", "su", and "passwd".

much less, that said person is not familiar with using 'single user mode',
'recover disk', etc.

you sound more like a security and system risk.

over looking such, you first need to run these commands;

man passwd
or
  info passwd

man su
or
  info su

man sudo
or
  info sudo

either will show you that, when run as 'root user', command;

passwd username newpassword

will change password for username.
