Papercut can run on a Windows Server (2003, 2008 or 2008 R2) using windows print queues or a Novell Linux OES server with iPrint (CUPS & SAMBA), it is written in Java with some wrappers for the OS in use.

We originally ran it on a Server 2003 R2 (x86) but have recently updated to a Windows 2008 R2 (x64)print server. The main reason for the upgrade was to provide up to date drivers for Windows 7 32 & 64bit. We also run the Papercut MF version which costs A LOT more, but allows you to use it with external devices, such as photocopiers.

Papercut has some really useful features, Card recharge allows you to generate top up cards and print them out yourself. Then you just cut them up and given them to the office (or canteen) to sell to the students. Makes recharging much easier and no need for office staff to login to an admin console to top up accounts.

We recently had a student laptop roll-out (NSW DER), these laptops are not on our domain so needed an alternative way to print. Papercut has a feature called WebPrint which allows students to upload MS office or PDF files to a website and have them printed to the chosen printer. You need to run software for it on a windows pc (server or client) which automatically opens the document and prints it to the chosen printer. As our Print server is running Windows and is a virtual machine we just configured it to auto-login as a limited user we created and installed Office, and Acrobat.

We use the reports function for auditing staff accounts and charging printer usage back to faculties. Staff are automatically added to different charge accounts based on their AD group membership.

We have just started using Advanced Scripting to charge staff different prices than students on shared copiers and printers.
The following script is what we use, as it is based on how faculties are invoiced at the end of each term. It is based on the Papercut recipe “Discount for staff” with a few changes.

/*
* Change Pricing for staff
*
* Staff are charged based on cost to school.
*
*/
function printJobHook(inputs, actions) {

var DISCOUNT_GROUP   = "Staff-All";
var COST_COLOUR  = 0.07; // Click Rate of Colour
var COST_BW  = 0.02;  // Click Rate of B/W
var COST_A4  = 0.01;  // Price per page of A4
var COST_A3  = 0.03;  // Price per page of A3

/*
* This print hook will need access to all job details
* so return if full job analysis is not yet complete.
* The only job details that are available before analysis
* are metadata such as username, printer name, and date.
*
* See reference documentation for full explanation.
*/

if (!inputs.job.isAnalysisComplete) {
	// No job details yet so return.
	return;
}

if (inputs.user.isInGroup(DISCOUNT_GROUP)) {
	// Debug messages are written to [install-path]/server/logs/server.log
	actions.log.debug("Cost before discount: " + inputs.job.cost);

	// Initial 0
	var newCost = 0;

	// Includes Duplex
	if (inputs.job.paperSizeName == "A4") {
		newCost = inputs.job.totalSheets * COST_A4;
	}
	else {
		newCost = inputs.job.totalSheets * COST_A3 ;
	}

	newCost += inputs.job.totalGrayscalePages * COST_BW;
	newCost += inputs.job.totalColorPages * COST_COLOUR;

	 actions.job.setCost(newCost);

	actions.log.debug("Staff Pricing on " + inputs.job.printerName + " For " + inputs.job.totalSheets +
		" sheets had " + inputs.job.totalGrayscalePages + " B/W & " +
		inputs.job.totalColorPages + " Colour, Cost after discount: " + newCost);

	// Record that as discount was applied in the job comment.
	actions.job.addComment("Staff Pricing applied. Had " + inputs.job.totalGrayscalePages + " B/W & " +
	inputs.job.totalColorPages + " Colour");
	}
}

Other useful features:

• Students and staff see a summary of how many pages they are going to print, which helps reduce accidental printing of entire chapters of text instead of just a few pages.
• Logs and statistics show which printers are getting used, how much is getting printed, and who printed the document but didn’t collect it.
• Great support. I have contacted them over a number of issues and they have always gotten back quickly with good ideas, or have added features in later versions.

Downsides:

• Although the price for education version of Papercut NG is not too bad, to get the MF version which supports copiers it costs around twice as much. Also you then need cost recovery devices for the copiers ~AUD$1,800 each, and there are annual support and maintenance costs ~AUD$1,000/year.

If you want to get an idea of how much printing your staff and students or just want to keep a record of who is printing what (like you could do easily with iPrint)  try the free Papercut Print Logger.

This post is to assist in the setup of a BackupPC system able to backup in use files by using MS volume snapshots. It also has the benefit of only having the RSync daemon running during the backup which increases security.

This method is based on some other posts I have seen using VShadow, Backing Up Open Files on Windows with Rsync, and some suggestions on DiskShadow but goes further in using RSync as a system service giving full access to files, and removing the need to use winexe.

General Outline

1. Create a new user backuppc (try to match case of the user on Linux). Very limited rights
2. Install Cygwin with RSync, OpenSSH and configure them
3. Create a scheduled task to run as SYSTEM when triggered by a certain event
4. Set BackupPC server for passwordless login to host and modify Pre/Post Dump Cmds

Overview

In Windows 7 and Server 2008 R2 elevation is required to create snapshots. As a remote SSH connection cannot bypass UAC a way is needed to create the snapshot, bypassing the elevation prompt. I also wished to run the Rsync Daemon as SYSTEM user so it has rights to view all files.

To do this I moved all the elevated tasks into a Task Scheduler item that is set to run as SYSTEM, and is triggered by an Event log event.

1. BackupPC performs a password-less key SSH logon to client
2. It runs a script which creates an event log entry and then waits for RSync to start before returning to BackupPC and starting the backup.
3. Task scheduler is triggered by Event Log and starts DiskShadow as SYSTEM.
4. Disk shadow creates a shadow of any chosen volumes, mounts them and then starts RSync.
   It then waits for a file to be created by BackupPC at the end of the backup telling it to stop RSync and delete the snaphots.

Flow and triggers

Host PC

Create a new user, backuppc, you can limit this account further in Security policy after everything is configured.

Create a BackupPC folder and add the following scripts to it. These are also available in a zip file. Note: There is a file embedded within this post, please visit this post to download the file. You will need to modify paths depending on where you create the folder. I used C:\cygwin\BackupPC but a better location may be C:\cygwin\usr\share\BackupPC

Most of these scripts are just modified versions of the ones written for VShadow, changed to work with DiskShadow and Task Scheduler.

end function

Cygwin

Install Cygwin and choose to install packages RSync and OpenSSH

Start an elevated Cygwin (Run as an Administrator )

Config

Cygwin 1.7 changes the way to ignore NT Security from the nontsec environment to modifying fstab file.

In your prefered editor modify /etc/fstab and uncomment the bottom line and add noacl as below, this tells it to ignore security :

none /cygdrive cygdrive binary,noacl,posix=0,user 0 0

Run following to update group and user lists (if on a domain only add the users you want)

[bashlight=1]mkpasswd –l >/etc/passwd
mkgroup –l /etc/group[/bash]

OpenSSH

Configure Open SSH using ssh-host-config, create both the accounts it suggests for privilege isolation and running the service (cyg_service & sshd).
This should also automatically add the Firewall Exceptions (SSHD).

Setting up Keyless

Login as backuppc user.
Use

runas /user:backuppc cmd

Or

runas /user:domain\backuppc cmd

Run c:\cygwin\Cygwin.bat to start Cygwin as BackupPC user

You need to add the id_rsa.pub file from the BackupPC user on BackupPC server to C:\cygwin\home\backuppc\.ssh\authorized_keys If you have not already created one follow the instructions below in BackupPC – SSH section.

RSync

To install RSync as a system service use:

C:\cygwin\bin\cygrunsrv.exe -I rsyncd -d "RSync Daemon" -O --type manual -p /bin/rsync.exe -f "Used by BackupPC to remotely access files for backup" -a " --config=/etc/rsyncd.conf --daemon --no-detach"

Modify the /etc/rsyncd.conf file to reflect what drives you want to backup. It is better to edit this file later after you have modified the DiskShadowScript.txt and changed which drive letter it exposes shadows as.

Add a RSync exception to the firewall.

Open Windows Firewall with Advanced Security and choose Inbound Rules, New Rule, Program,  Next

Browse to C:\cygwin\bin\rsync.exe and then choose your options and name the rule

When finished open the rule, click Scope tab and add a Remote IP, that of the BackupPC server. This restricts RSync to only be accessible from BackupPC. You may also wish to similarly modify SSHD to only allow SSH access from BackupPC server.

DiskShadow

If you are backing up a windows Server 2008 or 2008 R2 host you already have DiskShadow installed. However, if you are running Windows 7 or Vista you will need to grab a copy from an equivalent server (x86 or x64). It is located in the System32 directory and you will also need the language file from the en-US folder.

I have zipped the files needed for x86 and x64 if you do not have immediate access to a Server.Note: There is a file embedded within this post, please visit this post to download the file. (The x86 files are from Server 2008 and x64 are from 2008 R2)

Copy the files from your architecture to the system32 directory and en-US subdirectory.

LogEvent

To generate the custom event log entry a tool from the Windows 2000 Resource kit is used, LogEvent, (Download). This needs to be either placed in the Path (e.g. Windows dir) or scripts need to directly call it.

Task Scheduler

The easiest way to configure this is to manually run LogEvent once to generate an event in the log.

Logevent.exe -r "BackupPC" -e 10 -s S "Backup Start"

Then open Event Viewer, Select the new BackupPC event and choose Attach Task to this Event, and in the wizard click next until it asks for the program, then give it C:\cygwin\BackupPC\backuppc.cmd

On Final page choose to Open Properties when you click Finish

Click the Change User or Group button and type in System as the user  and click OK. Also tick the Run with highest privileges box

BackupPC Server

SSH

This section is only needed if you do not already have keys generated for the backuppc user.

Login as backuppc user, either with password or simply “su – backuppc” from root

Generate SSH Keys, ssh-keygen –t rsa, do not set a password. Copy id_rsa.pub into C:\cygwin\home\backuppc\.ssh \authorized_keys

Test by running ssh -v backuppc@host to test the connection

BackupPC Host File

In the web interface change the following for the host.

DumpPreUserCmd:  $sshPath -q -x -l backuppc $host cscript "C:\cygwin\BackupPC\pre-cmd.vbs"
 DumpPostUserCmd: $sshPath -q -x -l backuppc $host echo "Complete: $xferOK" > /var/run/wake.up

Test Run

If you have existing backups from a previous RSync config, it is a good idea to run a full backup to ensure any in use files are part of the base. In my case I also changed the noacl flag which affected the file attributes RSync sees.

Tips

Set your antivirus to exclude the exposed drives. As they are read only it just slows down the reading of files by RSync.

Updates

• While writing this up I found a good alternative way of using VShadow with SSH to backup in use files, that uses the AT command instead of task scheduler to get around UAC, BackupPC with ssh/rsync/VSS on Windows Server. The only down side to this method is the SSH connection requires an Admin account, but if configured securely this should be fine. It also a lot simpler to configure as it does not require configuring Task Scheduler.

Windows mail seems to generate large amounts of ESENT messages in the log file as it tries to backup the mail database. It also create 5Mb of files for every user as they logon. As we don’t even use Windows Mail, just Outlook for staff I wanted to disable it.

There appears to be no easy way to remove it from the system, but you can prevent it from setting up the details for every user when the log on.

Download and runs the Microsoft Sysinternals program Autoruns as an Administrator and then under the Logon tab untick “Microsoft Windows” under both the Active Setup\Installed Components and the WOW6432Node\Active Setup\Installed Components.

Now when a new user logs in it will no longer set up Windows Mail files or shortcuts.

Autoruns Windows Mail Disable

As part of this rename we needed to change their Novell eDirectory account and home directory. We also needed to ensure linked systems such as an LDAP authenticated Moodle site and an IDM linked Active Directory (AD) domain were properly updated.

To perform the user account and folder rename we used Mass User from HBWare. This is a great program we already used for creating and managing home directories and quotas. There was a small bug in the rename area, but it was quickly fixed when brought to Hans’ attention.
Note: Before beginning you need to have a list of the old usernames and the new usernames. A simple two column Excel or CSV file would be fine.

Novell

Create Mapping File: The mapping file is used by Mass User to know what to rename the existing username to.

Use NDS Report ( http://www.novell.com/coolsolutions/tools/13908.html ) to create a list of all the accounts. You only want the DN and CN fields. Save this as an Excel or CSV file.

NDS Report: Select Student OU

NDS Report: Choose only CN

Create a new MS Access file and import the account list
Import the text / excel file that lists the old and new account names.
You now need to create a query that maps the cn to the old account name, and then use this to generate a list of the full old dn and the new account name.

Access: Mapping Query

Access: Query Results

You can then export this as a text file.

Access: Export as text file

Access: Export Delimited

You will need to set the field separate as ‘=’ and set the test qualifier to none.

Access: = as Delimiter and no Text Qualifier

You should end up with each line having format:
OLDNAME.OU.C=NEWNAME
Once the mapping file is generated you can apply it either to individual OUs (e.g. year groups), or to the entire Users container. I would recommend applying to small containers initially to allow checking for errors. After verifying all renames were performed correctly you can then apply the rename to your entire users’ container.

Mass User: Rename

IDM 3.0 – Active Directory

Before doing the mass rename we did some simple tests of renaming eDirectory accounts to see how they replicated to Active Directory. We determined that the individual renames were successfully propagated through IDM to automatically change the pre-2000 and logon name fields to match the new eDirectory account.
When performing the mass rename of accounts, AD was checked after doing each OU to check propagation was successful. We experienced no problems with IDM and all accounts were successfully synchronised with Active Directory.

Moodle

For Moodle we wished for users to retain their own accounts including all their settings and course information. To do this the username stored in the Moodle Database (DB) would need to be changed to the new username.
Before making changes to Moodle I recommend putting the site in admin mode and temporarily disabling your LDAP authentication. I only put the site in Admin mode and then had problems during migration as some students had attempted to logon after I had renamed the eDirectory accounts, but before migrating Moodle accounts. This created new user accounts in Moodle that prevented the update queries running due to duplicate key name problems (ie the old account would not rename to new one if one has already been created with the new name)
First you need to import your list of old and new account names into the database. If you already have it in a separate DB on your Moodle server you can use that, otherwise it is best to just to create a new table in the Moodle DB.
I used this query to check the mapping fields. You will need to adjust the fields and collation types for your own setup.
I use the IDNumber field to store the full DN, if you use a different field you will need to adjust this.

Validation:

# Shows the current username, the new username and the new IDNumber field for validation check.
SELECT mdl.`username` , ern.`StudentId` , replace( `idnumber` , mdl.`username` , ern.`StudentId`
COLLATE latin1_swedish_ci )
FROM moodle.`mdl_user` mdl, sbhsdata.`oasisStudentIdMap` ern
WHERE mdl.`username`
COLLATE latin1_general_ci = ern.`OldStudentId`

Update:

# Replaces the IDNumber field with the new username.
UPDATE moodle.`mdl_user` mdl, sbhsdata.`oasisStudentIdMap` ern
SET `idnumber` = replace( `idnumber` , mdl.`username` , ern.`StudentId` COLLATE latin1_swedish_ci )
WHERE mdl.`username`
COLLATE latin1_general_ci = ern.`OldStudentId`

# Replaces the mdl_user field with the new username.
UPDATE `mdl_user` mdl, `rename` ren
SET mdl.`username` = ren.`newname`
WHERE mdl.`username`= ren.`oldname`
Note: As can be seen by the queries, during the migration I did two separate updates, one to update the IDNumber field and another to update the mdl_user field. When I had completed migration I realised I had only needed to update the mdl_user field as Moodle would automatically update the value in IDNumber at next log on.

Round Up

The migration to the new accounts went well with no problems from student passwords or accounts, although we had a few instances of students using the old username instead of the new one.

Since performing the change we have also implemented a Papercut system which would have required the additional step of renaming all of its accounts to ensure student balances were carried across.

A great tool is Wisesoft Password Control which allows you to just type in the username, it will display info about the account and give you the option to change the password, enable/disable the account and unlock the account.
It is ideal to make available to teachers for resetting the student passwords if you use the Delegate control option in AD Users and Computers for your student OU’s.

The other useful tool on the website is a pair of tools Bulk Password Control and Bulk Modify. These allow you to bulk reset the password for a large group of students, or modify the attributes for a large number of users. It can read these in from a CSV file, and match the CSV entires to either sAMaccountName or some other user attribute. You can also set the attribute based on their existing attributes.

After downloading it will ask you for a code that you can get with a free registration on their site.

After looking around online I found a great free utility that displays the info in an easy to explore graphical view. OverDisk scans the drive or folder (this took around 10 mins for a drive containing hundreds of home directories) and then you can save the data so it does not need to constantly rescan (unless you make changes to files).You can also have it only rescan a certain subfolder rather than the entire drive again.

It presents the information in a colour coded pie chart, allowing you to easily see which folders and files are using the most space.

You can click on the folder and the pie chart will change to reflect that folder or click the middle of graph to go up a level. Right clicking on a folder gives you an easy option to Open or Explore in Explorer.

I use it for nearly all my text based programming (PHP, HTML, CSS, CMD, JS, etc), for editing configuration files and reading Linux text files (i.e. only LF no CR).

It has replaced my previous one, ConTEXT, as my primary editor.

• It has a tabbed interface which makes it easy to work on multiple files
• good syntax highlighting for a wide range of languages
• good regular expression find and replace, as well as find in files in a directory
• can change shortcut keys
• does manually indenting but to my knowledge does not auto-indent.

It used to be even better, but most recent version does not include the HexEditor plugin from previous releases (although it does appear to still work if it is installed).
The Hex Editor is now available as a plugin for the Unicode version.

Overall a great freeware application.

Available from Source forge: Notepad++

As it is self contained it is very easy to repackage as an MSI for deployment or it can run straight off the network without installation (although it is a bit slow to load this way).

VLC runs on Windows, Mac and Linux so it can provide a uniform interface across platforms.

The latest version, 0.8.6d fixes some security problems and improves playback on Mac.

EZ GPO can be deployed by MSI across the network through either AD or Zenworks. You then add the supplied ADM to a group policy and set the idle times for switching monitor off, and putting computer into sleep, hibernate or standby modes.

One other option of EX GPO that makes it very attractive for laptops, is it can allow limited user accounts to change power settings on Windows 2K / XP. As most users will have experienced, Windows stores power settings in HKLM, so a standard user can not specify times for power saving. This can be very annoying if used during presentations, etc.
EZ GPO has an option that fixes this allowing the changing of the power policy.

Finally one other use for EZ GPO, against what was originally intended. If you have a PC that is locked down, but needs to be on continuously (such as a kiosk or display PC) you can use EZ GPO to prevent visible power saving options from starting. i.e No standby mode, or monitor savings. I would however recommend spinning down HDDs .

You can connect to your AD server without knowing any LDAP paths, just use your standard login.

Can also take snapshots to allow you to see what effect changes have on AD.
