1. Save the following to /usr/bin/writecheck

   #!/bin/bash
   FILE="$1"
   
   [ $# -eq 0 ] && exit 1
   
   if [ -w "$FILE" ]
   then
   nano $FILE
   else
      echo "You Do Not Have Write Acess To $FILE"
      echo -n "Do You Want To Continue (y/n)?"
      read reply
      [ $reply == "y" ] && nano $FILE
   fi

2. Allow the script to be executed

   chmod +x /usr/bin/writecheck

3. Finally we need to add a alias for it

   echo "alias nano='writecheck'" >> /etc/bash.bashrc

nano /etc/modprobe.d/aliases

By default you will have the following line

alias net-pf-10 ipv6

Replace it with the following

alias net-pf-10 off
alias ipv6 off

You can now remove all the ipv6 stuff from /etc/hosts and once you reboot ipv6 will be disabled

1. We need to install the following packages on our LDAP server

   apt-get install libnss-ldap libpam-ldap nscd

   LDAP Account for root: cn=admin,dc=home,dc=local
   Password: your-ldap-admin-password
   Make local root database admin: yes
   Database require logging in: No
   Root login account: cn=admin,dc=home,dc=local
   Root login password: your-ldap-admin-password 

Configuration Files

1. /etc/libnss-ldap.conf

   nano /etc/libnss-ldap.conf

   host IP-OF-LDAP-SERVER
   base dc=home,dc=local
   bind_policy soft
   rootbinddn cn=admin,dc=home,dc=local

2. /etc/pam_ldap.conf

   /etc/pam_ldap.conf

   host IP-OF-LDAP-SERVER
   base dc=home,dc=local
   rootbinddn cn=admin,dc=home,dc=local

3. Now we need to add pam_ldap so some of the pam configs

   nano /etc/pam.d/common-account
   account sufficient pam_ldap.so
   account required pam_unix.so
   #if you want user homedir to be created on first login
   #session required pam_mkhomedir.so umask=0022 skel=/etc/skel/ silent
   
   nano /etc/pam.d/common-auth
   auth sufficient pam_ldap.so
   auth required pam_unix.so nullok_secure use_first_pass
   
   nano /etc/pam.d/common-password
   password sufficient pam_ldap.so
   password required pam_unix.so nullok obscure min=4 max=8 md5
   
   nano /etc/pam.d/common-session
   session sufficient pam_ldap.so
   session required pam_unix.so
   session optional pam_foreground.so

4. Finally we need to edit /etc/nsswitch.conf

   nano /etc/nsswitch.conf

   passwd:         compat ldap
   group:          compat ldap
   shadow:         compat ldap

Well this is more simple. Just download and install dropbox and use this url (yes its a referral but it gives you 0.25 gb extra)

First go to 1Password in the menu then preferences then keychain then click move. Use something like this

After that on your other computer do to First go to 1Password in the menu then prefs then keychain then move (Again). Go to your dropbox and pick the same file.

So first of all what is batch file? Its a file with a list of commands that are executed by command prompt(CMD) to open your cmd window go to start > run > cmd

Basic Commands

1. [batch]@echo off[/batch]
   This removes the "C:\Documents and Settings\Administrator>" part
2. [batch]cls[/batch]
   This clears all writing off the CMD window
3. [batch]color backgroundcolor-textcolor[/batch]
   This allows you to change the color of the text

   0 = Black       8 = Gray
   1 = Blue        9 = Light Blue
   2 = Green       A = Light Green
   3 = Aqua        B = Light Aqua
   4 = Red         C = Light Red
   5 = Purple      D = Light Purple
   6 = Yellow      E = Light Yellow
   7 = White       F = Bright White

   Example command:
   [batch]color 04[/batch]
   This example would give you red text on a black background

4. [batch]goto TEXT[/batch]
   This will cause the script to go to a particular section of the script it will be explained more later on in this tutorial
5. [batch]pause[/batch]
   This Pauses the command prompt and displays the message press any key to continue...

Your first batch script

For this example we will make a simple hello world script.

To get started open up notepad start > all programs > accessories > notepad
[batch]@echo off
color 64
echo hello world
pause[/batch]
Save it with a .bat extension and then double click on it to run it. It should print the text "hello world" in red font on a yellow background and then pause

The goto command

The goto command tells the script to go to a certain part of it
[batch]goto bush[/batch]
this will cause the script to go to the line that starts with
[batch]:bush[/batch]
Example:
[batch]@echo off
echo Hello, this script will repeat the message "you will see this over and over again" to cancel it press ctrl+c
pause
:bush
echo you will see this over and over again
goto bush[/batch]
The message was repeated because after it was printed the goto command made the script start again from :bush

Launching programs from a batch script

Using the start command we can start programs

Example:
[batch]@echo off
color f1
echo this script will open google.com in your default internet browser
pause
start http://www.google.com[/batch]
