DD-WRT on a Videotron reflashed DIR-825

The Videotron custom firmware does not allow local upgrade. On the firmware update page there is a nice "Firmware upgrade: Disabled" and that's where the update ends in the main interface.
In order to update, I've rebooted in  recovery mode browser by keeping the reset pressed white plugin the power. However, the upload process was always staying at 0% and didn't finished;
Then I've hexedited the factory-to-ddwrt_NA.bin and changed the last byte in the file from "0" to "2" - still no luck;
I've tried uploading directly from the shell: "ifconfig enp0s25 192.168.0.34 up && curl -0vF files=@factory-to-ddwrt_NA.bin http://192.168.0.1/cgi/index" - nope, still nothing;

The solution was deceivingly simple: I've put a switch between the D-Link and the computer - then the curl upload worked perfectly!

Copy standard switch port groups from one esx host to another

The below code asks for lmvap-vcs60 credentials, connects to Vcenter, and copied aesx11 vSwitch2 portgroups over to a new host called aesx05 using vSwitch1. (or so said my buddy Josh O. who wrote it) 

$vccred = get-credential

connect-viserver -server lmvap-vcs60.domain.tld -credential $vccred

$dest = get-virtualswitch -name vSwitch1 -vmhost aesx05.domain.tld

$source = get-virtualportgroup -vmhost aesx11.domain.tld -virtualswitch vSwitch2 -standard

$countvar = $source.count

for ($a=0 ; $a -le $countvar-1 ; $a++)

{

$pgname = $source[$a].name

$vlan = $source[$a].VLANID

new-virtualportgroup -virtualswitch $dest -name $pgname -VLANID $vlan

}

disconnect-viserver -server lmvap-vcs60.domain.tld -confirm:$false

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 printers.cab
- 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 printers.cab \\%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 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
Wscript.Quit

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)   
Next   
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
