Deploy local printers to Windows XP

- Go to a computer without any printer installed, login as administrator and  install all the printers you need to deploy.
- download & run UTFG://printmig.exe go to Actions and click on Backup - save the cab file with the name
- download  UTFG://ListComps.exe and run listcomps.exe /D:MY_DOMAIN >> comps.txt
  (replace MY_DOMAIN with the domain you're in) edit the file comps.txt in order to remove unwanted computers, servers...
- in a command prompt type the following line: for /F %r in (comps.txt) do printmig.exe -i -r \\%r 
- now watch printmig spawning an instance for every computer and pushing the drivers to all of them
- enjoy a beer 

if before you want to remove ALL the old network printers you can use my (somehow pretty drastic) method of deleting.
Add this .vbs script to the user login or use psexec.exe to launch it:

------------------BEGIN HERE--------------------
' removepr.vbs - Windows NT Logon Script. 
' VBScript - Silently remove ALL network printers
' -----------------------------------------------------------------------'

Set objFSO = CreateObject("Scripting.FileSystemObject") 
Set objNet = CreateObject("WScript.Network")
Set WshShell = CreateObject("WScript.Shell")
Set wmiLocator = CreateObject("WbemScripting.SWbemLocator")
Set wmiNameSpace = wmiLocator.ConnectServer(objNet.ComputerName, "root\default")
Set objRegistry = wmiNameSpace.Get("StdRegProv")
Const HKEY_CLASSES_ROOT  = &H80000000
Const HKEY_CURRENT_USER  = &H80000001
Const HKEY_LOCAL_MACHINE = &H80000002
Const HKEY_USERS         = &H80000003
strComputer = "."

' If this script already run once for this user, then EXIT
userprrf = WshShell.Environment("PROCESS")("UserProfile") 
'wscript.Echo userprrf
If (objFSO.FileExists(userprrf & "\sctwashere.txt")) Then
blah = "let's have some fun"
End If

' Deletes RegistryKey with all subkeys in Network printers
sPath = "Printers\Connections"
lRC = DeleteRegEntry(HKEY_CURRENT_USER, sPath)
Function DeleteRegEntry(sHive, sEnumPath)
' Attempt to delete key.  If it fails, start the subkey enumration process.
lRC = objRegistry.DeleteKey(sHive, sEnumPath)
' The deletion failed, start deleting subkeys.
If (lRC <> 0) Then
' Subkey Enumerator   
On Error Resume Next   
lRC = objRegistry.EnumKey(HKEY_CURRENT_USER, sEnumPath, sNames)   
For Each sKeyName In sNames      
If Err.Number <> 0 Then Exit For      
lRC = DeleteRegEntry(sHive, sEnumPath & "\" & sKeyName)   
On Error Goto 0
' At this point we should have looped through all subkeys, trying to delete the key again.   
lRC = objRegistry.DeleteKey(sHive, sEnumPath)
End If
End Function 
'Now let's recreate only the "root" Key we deleted before
objRegistry.CreateKey HKEY_CURRENT_USER,sPath

Cloud Print on an old local printer

add printer in local cups. make sure it prints. some printers require loading a firmware stub. in my /etc/rc.d/rc.local I have the following line:
/usr/share/hplip/ -n -p HP_LaserJet_1020

open chrome as a normal user (in our case luser23)
go to chrome://devices/
click add printer. follow instructions.

create the following init script and make sure is executed at startup

cat /etc/init.d/cloudprint

# Start / Stop cloudprint daemon
# description:  Start / Stop cloudprint daemon
# chkconfig: 345 99 9
# Provides: cloudprint
# Default-Start: 3 4 5

# See how we were called.
case "$1" in
 gprintf "Starting cloudprint: "
 /usr/bin/su -l $user -c "$options" && success || failure
 gprintf "Shutting down cloudprint:"
 killproc chrome && success || failure
 status chrome
 $0 stop
 $0 start
 gprintf "Usage: %s\n" "$0 {start|stop|restart|status}"
 exit 1
exit 0

cat /etc/cloudprint.conf

options="/opt/google/chrome/chrome --type=service --enable-cloud-print-proxy --no-service-autorun --noerrdialogs --disk-cache-size=1 --media-cache-size=1 --disk-cache-dir=/tmp/chrome.$$ &"

or just add in /etc/rc.d/rc.local the following line:
su -l luser23 -c '/opt/google/chrome/chrome --type=service --enable-cloud-print-proxy --no-service-autorun --noerrdialogs --disk-cache-size=1 --media-cache-size=1 --disk-cache-dir=/tmp/chrome.$$ '

Install HPSUM on an rpm base distro

mount /dev/cdrom /mnt
cp /mnt/compaq/psp/linux /tmp/
cd /tmp/linux

- check for the prerequisite, usually you need expect, kernel-headers, rpm-build, gcc, libnl, redhat-rpm-config, openipmi and net-snmp  either form the redhat installation dvd (rpm -Uvh package), or you can use "yum install package" if you have yum repositories configured.
- you need to manually install hp-snmp-agents package from the hp dvd, it is not installed by hpsum (I presume it's a glitch). hp-snmp-agents needs hp-health (you find them both in the /tmp/linux directory that you just copied from the dvd)
- re-run ./hpsum untill you have no conflicts/unresolved dependecies!
- after installation and reboot run /sbin/hpsnmpconfig - you have to provide only the readonly (public) and the read/write (private) comunity for snmp.
- if everything seems ok, edit /opt/hp/hp-snmp-agents/cma.conf lin 22: trapemail . at the end of the line replace root with your email address - REMEMBER: you need a functional sendmail in order to be able to send emails!

HP Important Note:   The server needs to have 'sudo' installed in order to start or stop the snmp daemon and to send test traps.   'sudo' grants controlled root access to groups or users.   If installed after hp-snmp-agents please run a '/sbin/hpsnmpconfig'. In case of VMware ESX 3.x series, please run '/etc/init.d/hpasm reconfigure' after installation of hpasm.   These buttons will NOT work if 'sudo' is configured to only run when the user is logged into a 'real' tty.   To be able to perform the operations of start, stop, restart of the snmpd daemon, the user must comment out the line 'Defaults requiretty' in the /etc/sudoers file.   See man sudoers for details about the 'requiretty' flag.   If present, this flag will need to be removed from the '/etc/sudoers' configuration file.   The 'send trap' button also requires a tool snmptrap to be present on the system.   This tool is often bundled with the snmp stack (Suse) or in a package called 'net-snmp-util' (Red Hat).

DNS Adbock on router

In case you have, like me, a secodary dns on your DD-WRT router, you need a dns adblock on it too. By modifying the excellent tutorial from I came to this script:

Using Intel AMT’s embedded VNC server

Intel Chipsets with vPro/Intel AMT, paired with a Core i5/i7 or Xeon with integrated graphics, have a feature called Remote KVM.

To activate it, press Ctrl-P at the BIOS - this brings you to the MEBx menu, set a password (minimum 8 characters, mixed case, numbers and special characters are enforced - try to avoid #@$% - use star or exclamation), configure the network settings (DHCP, or static - it can even match the OS’s IP address!), enable Remote KVM and disable User Opt-In.

in order to set it up, download the Intel AMT SDK from extract the ZIP and open ./Windows/Intel_AMT/Bin/KVM/KVMControlApplication.exe. (I had to install .net 2.0 in my wine in order to be able to run it.)
There, you can enable KVM by clicking "Edit Machine Settings" as seen in the following screenshot:

KVM Status can either be set to
-“redirection ports” (meaning it will only be accessible to clients that specifically support Intel AMT, such as RealVNC Viewer Plus or Intel’s KVM Console, the former of which costs $100, the later constantly overlays a RealVNC logo on the screen), or to
-“default port” (meaning it will be accessible on TCP port 5900 with any VNC client), or to
-“all ports” (which is the combination of both).
If you enable VNC access, you will also need to set an RFB Password. Warning, the password gets truncated at 8 characters but     at the same time has the security requirements identical to the general AMT password (Capital, small letter, number and special-character - WARNING: underscore is not special char, @$%&| are NOT allowed, choose star or exclamation to play safe).
If you disabled User Opt-In in the MEBx menu, you can disable it here as well.

Now you can use almost any VNC client you like (KRDC, Real, Ultra, and Tight VNC works fine, while TigerVNC seems to be unable to auth, and Apple Remote Desktop appears to cause the VNC server to freeze - it's Apple crap, what do you expect?).

Two things worth mentioning:
1: the initial BIOS splash screen is not visible during a KVM connection (not even on a directly-attached screen), so to get to the BIOS, you needed to blindly hit the F10.
2: it is not possible to enter the MEBx menu during a KVM connection (probably for security reasons), if you hit the corresponding CTRL+P key, it immediately exits and continues normal boot; if you establish a KVM connection while already in MEBx, you get disconnected immediately.

 If you’re building a home server, you should definitely consider getting system with Intel vPro/AMT 6.0 or later, you get ILO-like remote management capabilities for free.

Oh yeah, http://your_machine:16992 gives you access to logs, power control, network setup, users, exactly the same way ILO does!

And of course the OS has no idea something is running below him, there is no CPU load, on the host netstat shows no other connections except my ssh:
 tcp        0      0       ESTABLISHED 2314/sshd

while from my workstation we can see a second connection to the VNC port 5900:
tcp        0      0          ESTABLISHED 13362/ssh   
tcp        0      0        ESTABLISHED 29457/krdc

 Note the black blinking monitors in the upper-right corner - that screams "AMT":

Error 512 - rear chassis fan not detected on a Small Form Factor

as per hp site:
"Although the HP Compaq 8200 Elite Small Form Factor PC has no rear chassis fan installed, this error message may arise when the front panel cable assembly was damaged after a system repair attempt.
In a HP Compaq 8200 Elite Small Form Factor PC, Pin10 on the front panel cable connector is used to tell the system BIOS, that the chassis is a Desktop model, not Microtower model. This is necessary because the system board is also used in HP Compaq 8200 Elite Microtower PC, which has a rear chassis fan installed. Pin10 is not connected there.
If the cable on Pin10 of the connector in a HP Compaq 8200 Elite Small Form Factor PC was damaged accidently and therefore has no connection to the system board, the BIOS assumes that it is a Microtower model and therefore checks for a rear chassis fan."

There is a problem with the front panel connector:

Let's remove it and look, the pin 10 is not connected while pin 5 (usually unused) it is:

We just need to remove the plug from pin 5 and move it to pin10:

Finally the ground is moved from pin 5 to pin 10:

Resize an LVM partition on a HP Proliant server

1. Install HP Proliant support pack 

2. If you've installed the PSP before and it is already running on your server, you can skip this step, otherwise start HP Array Configuration Utility Online for Linux. 
cd /opt/compaq/cpqacuxe/bld
./cpqacuxe -R
note: after finishing online configuration utility, you might want to stop it by running
./cpqacuxe -stop

3. Expand array and logical drive
Go to https://localhost:2381 and click on array configuration utility link.
Click on expand array - it will take some time to finish (like 8hrs). After the expansion is finished, a new button called 'expand logical drive' will appear, clicking on it will finish expanding the array.

4. Make Linux kernel recognize the new size of your hardware raid5
Reboot Linux server, run  'partprobe' or 'sfdisk -R /dev/cciss/c0d0' followed by  'fdisk -l /dev/cciss/c0d0' multiple times, 'till it shows the new size.
You might have to reboot multiple times if the new size does not appear at fdisk -l.

5. Enlarge partition with fdisk - DANGEROUS, please have a full backup first!
fdisk /dev/cciss/c0d0  (you might consider using fdisk -u /dev/cciss/c0d0 - it will display the size in sectors instead of cyclinders)
"p" - take note where the /dev/cciss/c0d0p2 (your extended partition) starts!
press "d" then "2" to remove the c0d0p2 partition - yes you wil DELETE the partition, don't reboot, don't move, dont even breathe on top of that server!!!
press "n" for new, then "p" primary partition to use the full space
Make sure the old and new partition starts at the same cylinder or sector position, otherwise, all your data will be destroyed!!!
press "t" to change partition type to LVM
"w" to write
"q" to quit
now you will need to reboot again!

6. Resize physical volume size, logical volume size and perform file system online increase:

After reboot, check again the new size:
[root@log ~]# fdisk -l /dev/cciss/c0d0
Disk /dev/cciss/c0d0: 1799.7 GB, 1799797127168 bytes
255 heads, 63 sectors/track, 218812 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

           Device Boot      Start         End      Blocks   Id  System
/dev/cciss/c0d0p1   *           1          13      104391   83  Linux
/dev/cciss/c0d0p2              14      218813  1757509959+  8e  Linux LVM

Let's see ho many free phisical blocks we have:
[root@log ~]#vgdisplay -v | grep "Free PE"
    Finding all volume groups
    Finding volume group "VolGroup00"
  Total PE / Free PE    54337 / 17879

Now let's resize the phisical volume:
[root@log ~]# pvresize /dev/cciss/c0d0p2
  Physical volume "/dev/cciss/c0d0p2" changed
  1 physical volume(s) resized / 0 physical volume(s) not resized
  note: we used vgdisplay -v to check the number of free PE, let's say it's 17879.

Now let's extend the lvm: 
[root@log ~]# lvextend -l +17879 /dev/VolGroup00/LogVol02
  Extending logical volume LogVol02 to 1.60 TB
  Logical volume LogVol02 successfully resized

And finally we will resize the filesystem:
[root@log ~]# resize2fs /dev/VolGroup00/LogVol02
resize2fs 1.39 (29-May-2006)
Filesystem at /dev/VolGroup00/LogVol02 is mounted on /data; on-line resizing required
Performing an on-line resize of /dev/VolGroup00/LogVol02 to 430276608 (4k) blocks.
The filesystem on /dev/VolGroup00/LogVol02 is now 430276608 blocks long.

Ofc, steps 4 to 6 can be replaced with running offline gparted from a CD...
