Bought used need to by pass password


You didn't say what OS you are using.

1.To try and remove the password protection you can power off the PC.
remove the side panel and then remove the battery. Leave it for 10 minutes, refit the battery and then power up the PC. The password protection may have been removed.

2. Or at start up, enter the bios settings. You may be able to disable the password from within the settings.

3. If you're not bothered which OS you use, try a new install of XP or Windows 7.

If you don't have XP or Windows 7, ask a friend to download linux and burn it onto a dvd for you(or put it onto a usb flash drive). Put the linux dvd into your dvd drive and restart the computer. You will have the choice of completely erasing Windows, or installing Linux alongside Windows.

Linux is free. It will do everything Windows can do. Linux comes with its own version of 'Office'. The best free versions of Linux are Ubuntu or 'Mint'.

You can download Ubuntu here: http://www.ubuntu.com/download/desktop

Webcams do NOT work in Linux. Apart from that, Linux will do everything Windows can do (but free!) and you won't ever get a virus.

How to Setup Linux Mail Server


<p><span>Email is an important part of any Web site that you create. In a home environment, a free web based email service may be sufficient, but if you are running a business, then a dedicated mail server will be required. <span>A mail server is an application that receives incoming e-mail from local users (people within the same</span><span> </span><span><span>domain)</span> and remote senders and forwards outgoing e-mail for delivery, as example Microsoft</span><span> </span><span><span>Exchange</span>, Gmail,</span><span> </span><span><span>etc.</span></span></span><span> <span> </span></span><span><span>The system uses</span></span><span><span> </span></span><span><span>SMTP </span></span><span><span>(Simple Mail Transfer Protocol) or <span>ESMTP </span>(extended SMTP) for sending e-mail, and either</span></span><span><span> </span></span><span><span>POP3</span></span><span><span> </span></span><span><span>(Post Office Protocol 3) or <span>IMAP</span></span></span><span><span> </span></span><span><span>(Internet Message Access Protocol) for receiving e-mail</span></span><span><span>. </span></span><span><span>In windows forum</span></span><span><span> most of workstations are use Microsoft Exchange server or outlook express. In Linux forum there have also an easiest option to send and receive mail. In Linux configuration of mail server is easy flexible too.</span></span><span></SPAN><br> <p><span><span> </SPAN>In most of Linux workstation RedHat Linux are used for their Server. In RedHat Linux we use sendmail to create a mail server that will relay your mail to a remote user's mailbox or incoming mail to a local mail box. On our RedHat we will find sendmail's configuration file as /etc/sendmail.cf. If you download and compile sendmail you would find it in /etc/mail/sendmail.cf. To configure sendmail you have basically 2 options. Either you edit the sendmail.cf file directly or you create the sendmail.cf from an m4 file such as sendmail.mc. Here to explain the process I will list the steps to produce a custom sendmail.mc file.</SPAN><br> <p><span></SPAN> <br> <p><span><span><b>SendMail Configuration:</b></SPAN></SPAN><span> </SPAN><span><span> </SPAN>In Redhat Linux dovecot and sendmail packages are used as service demon for Mail server. At first I install the available sendmail RPM package by YUM and also the dovecot RPM. After installation first I have edit the sendmail .mc file. After installation of sendmail package it locates as sendmail.mc in /etc/mail. In the sendmail.mc file I have find the line DAEMON_OPTION and edit it with # before the line to uncheck it. Then I find Local Domain and edit it also with the system FQDN. After editing save the sendmail.mc file. After exiting from sendmail.mc I moved this .mc file to sendmail.cf with m4. Here the SendMail configuration is complete. Then I go to the /etc/dovecot.conf file and edit it. I just find the protocol line and uncheck this line. After that I save this .conf file. After all configurations I have start the service demons with chkconfig command and restart the both services. And the mail server was going on swiftly.</SPAN><br> <p><span><span> </SPAN>So it is very easiest job to configure a mail server in RedHat Linux enterprise server.</SPAN>

DHCP Server configuration in Linux


Linux is a UNIX based operating system. It is a server operating system. REDHAT Linux is Enterprise version of Linux. Now a day's Most of corporate sectors use red hat Linux as server in their company because it is secure very much.

Full form of DHCP "Dynamic Host Configuration Protocol. DHCP server assigns IP addresses and other network configuration information like subnet mask, broadcast address, etc to computers on a network. The DHCP assignments are the following.

Lease Request: Client broadcasts their request to DHCP server with a source address of 0.0.0.0 and a destination address of 255.255.255.255.
IP lease offer: DHCP server replies with an IP address, subnet mask, network gateway, name of the domain, name servers, duration of the lease and the IP address of the DHCP server.

Lease Selection: Client receives offer and broadcasts to al DHCP servers that will accept given offer so that other DHCP server need not make an offer.

The DHCP server then sends an ack to the client. The client is configured to use TCP/IP. Lease Renewal: When half of the lease time has expired, the client will issue a new request to the DHCP server.

Installation of DHCP server: First of all while install the RedHat Linux enterprise version server be careful about the ports and the services must be turned on. To create DHCP server in Linux first download DHCP RPM package and install with "rpm-ivh" command. Where I have done it there I have create YUM server, so easily I have download and install it by YUM (yum install dhcp version). DHCP package will locate in /usr/share/doc/at Linux file system. I copied the DHCP's files from /usr/share/doc/ to /etc/dhcpd.conf.. Then I started to configure the dhcpd.conf file to route the DHCP server in there local network. I have open the configuration file with "vi" command. Then commented out the lines from "default gateway to option netbios" because system don't read the commented lines. After that I set the range of IP address in dynamic- bootp of their local assumption of system. I have change the "next-server" with the dhcp server name and have also change the fixed address with the dhcp server IP address (end range of dynamic IP). It is very easy job to configure DHCP server. After configure the .conf file of dhcp just turn on the service with "chkconfig" command and restart the dhcp service. After that entire job I reboot the system. And after rebooting of server I turned on the other client system. While startup the client system without static IP address all of those picked up IP from dhcp server and going on successfully. I have prefer the command line mode to do the total job.
The DHCP server configure file is following:

ddns-update-style interim
ignore client-updates

subnet 192.168.1.0 netmask 255.255.255.0 {
# The range of IP addresses the server
# will issue to DHCP enabled PC clients
# booting up on the network

range 192.168.1.201 192.168.1.220;
# Set the amount of time in seconds that
# a client may keep the IP address

default-lease-time 86400;
max-lease-time 86400;

# Set the default gateway to be used by
# the PC clients

option routers 192.168.1.1;
# Don't forward DHCP requests from this
# NIC interface to any other NIC
# interfaces

option ip-forwarding off;

# Set the broadcast address and subnet mask
# to be used by the DHCP clients

option broadcast-address 192.168.1.255;
option subnet-mask 255.255.255.0;

# Set the NTP server to be used by the
# DHCP clients

option ntp-servers 192.168.1.100;

# Set the DNS server to be used by the
# DHCP clients

option domain-name-servers 192.168.1.100;

# If you specify a WINS server for your Windows clients,
# you need to include the following option in the dhcpd.conf file:

option netbios-name-servers 192.168.1.100;

# You can also assign specific IP addresses based on the clients'
# ethernet MAC address as follows (Host's name is "laser-printer":

host laser-printer {
hardware ethernet 08:00:2b:4c:59:23;
fixed-address 192.168.1.222;
}
}
#
# List an unused interface here
#
subnet 192.168.2.0 netmask 255.255.255.0 {
}

How To Password Protect & Decrypt Microsoft Office 2010 Documents


Microsoft office 2010 , the next big buzz from Microsoft after Windows 7, is a productivity suite for Microsoft Windows,and the successor to Microsoft Office 2007.

Screenshots of Microsoft Office 2010
6954b7a.png

Not long ago I was just wrote an article about How to Password Protect Microsoft Office 2007 Documents. Now I’ll write a similar article about office 2010 by popular demand.
Microsoft Office 2010 indeed simplified the process to password protect and encrypt office documents. Which was considered a commendable improvement over password protecting documents under Office 2007. as the new process for Office 2010 is consistent across the core Office product line which including Word 2010, Excel 2010, PowerPoint 2010 etc. so here I only need to show you how the process just once using Microsoft Word 2010 as example.
Follow the step-to-step guide To Protect A Word 2010 Document Using Built-in Password Encryption
1. Click the File tab, then Click Info. On the menu to the right Click Protect Document and
Click Encrypt with Password.

2. The Encrypt Document dialog will appear, Type in a password and then Click OK to finish.

Please note – It’s very important to use a STRONG Password or Pass Phrase to protect your word document. Using a long PASS PHRASE (IE:I enjoyed myself today!) however with 10 or more characters will significantly increase the encryption strength of the document and decrease the likelihood someone will be able to break the encryption and gain access to your document.
After setting a password, your document should be protected!
Having password protected your word document? Someone should ask what if I forgot the password. So that’s what I’ll show below.
Follow the step-to-step guide To decrypt Word 2010 Document Using word password recovery 5.0
With this user guide, even a new user can fully control Word Password Recovery 5.0 in less than a minute.
Step1: Click “File>Open” in the Menu or the “Open” button to browse in the Word document.


Select your file in the Open File window, and click “Open“.

Step2: Select “Brute-force Attack (Trying All Possible Combinations)“.

Step3: Click “Start” button in the Menu to initiate the program.

Step4: The program is searching the password. Some time later, a message box pops up to you, displaying the expected password. Click “Remove All Passwords from the File” to remove all passwords (Password to Open and Password to Edit) from the file. Click “OK“.

Following this article, you could password protected your office 2010 and decrypt password protected office 2010 with ease.

How to Password Protect And Access a Password-Protected Word Document


How to Password Protect a Microsoft Word Document If you are working on documents that are important and shouldn’t be changed, then there is a way to password protect them so they cannot be changed except by you. You can also make the documents unavailable to open unless the person has the password as well.
Instructions
Things You’ll Need:
  • A Computer
  • Microsoft Office with Microsoft Word
  • Word Documents
  • General Knowledge of Microsoft Word
Step 1
Open Microsoft Word and open or create the document that you want to password protect.
Step 2
Click on “File” in the toolbar and select “Save As”.
Step 3
Click on the “Tools” menu and select “Security Options”.
Step 4
This will open a “Security Options” window. You may now set a password under the “Password to open” box, “Password to modify” box or both.
Step 5
Once you type in the password of your choosing you can opt to make the file “Read-only” by checking the appropriate box. You may then click “OK” to save your changes and then save your document as usual.
How to Access a Password-Protected Word Document Accessing a password-protected Microsoft Word document is only possible when you have the correct password that opens the document. Encryption and security levels differ for separate versions of Word. Microsoft 2007 doesn’t offer any solutions to allow a user to retrieve forgotten passwords and Microsoft does not allow its employees to help in retrieving or breaking passwords. If you do not have the correct password for the document, you will be unable to access it.
Instructions
Things You’ll Need:
  • Microsoft Word

Step 4
Click the “Open” button or hit the “Enter” key. If the password was correct, the document will open. If it was not correct, another window will display advising you the password was incorrect and prompting you to try again.

My E-Mail Server is down


the solution i will be posting assumes you already have postfix installed in the new machine and that your new postfix server is able to relay mails. Old configurations has been copied/transported to the new server ( and the only remaining task is to move all the mails to the new postfix server.

copy /home (your maildir) to your new server - check your postfix configuration to verify your maildir

also make sure you have copied

/etc/passwd
/etc/shadow
/etc/group
/etc/gshadow
/var/spool/mail

to your new mail server ( these are your mail related files)

Note: This is assuming you have identical setup you have with your old email server. double check your postfix configuaration before proceeding.

Good Luck
