I never knew….
If you cannot continue in Chrome because of an ERR_CERT_INVALID error, even after pressing Advanced: there’s a secret passphrase built into the error page. Just make sure the page is selected (click anywhere on the background), and type `thisisunsafe`

Personal reminder:

Download latest: https://ffmpeg.org/download.html
Run ffmpeg -i MyMovie.mkv and look for stream info, e.g.:

Stream #0:0: Video: h264 (High), yuv420p(tv, bt709/unknown/unknown, progressive), 1920x800, SAR 1:1 DAR 12:5, 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default)
Stream #0:1(dut): Audio: ac3, 48000 Hz, 5.1(side), fltp, 448 kb/s
      title           : Dutch
Stream #0:2(dut): Audio: ac3, 48000 Hz, 5.1(side), fltp, 448 kb/s
      title           : Flemish
Stream #0:3(eng): Audio: ac3, 48000 Hz, 5.1(side), fltp, 448 kb/s
      title           : English
Stream #0:4(dut): Subtitle: subrip (default) (forced)
Stream #0:5(dut): Subtitle: subrip
Stream #0:6(eng): Subtitle: subrip

Say, I would like to have the video with the Flemish audio and all the subtitles (since they don’t take that much space)

ffmpeg -i MyMovie_2160p.mkv -vf scale=640:-2 -ac 2 -af "pan=stereo|FL=FC+0.30*FL+0.30*BL|FR=FC+0.30*FR+0.30*BR" -map 0:v:0 -map 0:a:1 -map 0:s MyMovie_640p_2ch.mkv

-vf scale=640:-2	= video filter: 640p, -2 means keep aspect ratio for vertical pixels
-ac 2			= (convert to) 2 audio channels
-af "pan=......		= audio filter: copy multichannel audio without losing center channel (dialogs)
-map 0:v:0		= copy first (0) video stream
-map 0:a:1		= copy second (1) audio stream (Start from 0. So 0 would be Dutch, 1 Flemish, 2 English)
-map 0:s		= copy all subtitles 
but if you have non-convertible subtitles (bitmapped), then first map the desired sub and copy, e.g.: -map 0:s:3 -c:s copy

pfSense’s DNS resolver has the ability to do host overrides from the gui, but these are global overrides.
Unbound (the underlaying DNS resolver) has the ability to create DNS views to do different things based on source addresses.
It is located under Services - DNS Resolver - General - Custom options. It is a free format field.

Example:

server:
access-control-view: 10.123.12.0/24 vlan15activedirectory
access-control-view: 10.158.1.0/24 vlan16guest

view:
name: "vlan15activedirectory"
local-zone: "vpn.client.net" static
# adding the host as a zone results in NXDomain lookup

view:
name: "vlan16guest"
local-data: "vpn.client.net. 90 IN A 11.12.13.10"
# adding a specific host and map it to a specific ip

More info: https://unbound.docs … ring/tags-views.html

I’m always googling for this. What was that thing again that logs all output to a file?

2>&1

Bash example:

root@ubuntu:/mnt/sda6# rsync -av * /mnt/backup/sda6/ >/mnt/backup/readrrors.txt 2>&1

Dos example:

copy backup.log \\nas\share\weeklog.txt >output.txt 2>&1

If you have a printserver in your network and you want to change certain properties, e.g. print black/white instead of color, normally what you do is change the settings on the Advanced Tab - Default Settings Button. These are the settings a user inherits when first connecting to the shared printer.
But what if you want to revert these settings. You’d have to remove the printer from the userprofile and make sure the printer’s readded, in order to inherit the new default settings.

This is exactly what the following script does.
It also cleans removed/unshared printers, as it can only re-add printers that still exist.

on error resume next
Set WshNetwork = WScript.CreateObject("WScript.Network")

'## Enumerate all the current printers in the profile
Set oPrinters = WshNetwork.EnumPrinterConnections

For i = 0 to oPrinters.Count - 1 Step 2

'## Disconnect the printer
WshNetwork.RemovePrinterConnection ""& oPrinters.Item(i+1) &"", true, true
'## Readd the same printer (if still exists)
WshNetwork.AddWindowsPrinterConnection ""& oPrinters.Item(i+1) &"", true, true

Next

msgbox "Done"

You might want to comment the last line to make the script run totally silent.

Maybe it’ll be fixed in newer versions but todays latest version of Nokia OVI Suite is 2.1.1.1 and the latest firmware for my nokia E71 is 410.21.010.
So now everything’s up to date, still can’t sync contacts, agenda, etc with the OVI Suite. All i get is error “80043c94”.
Searched all over the net, but no solution. AARGH

Reason: You cannot have your application data (%appdata%) redirected. Revert to default settings (as part of your user profile, whichs makes your userprofile bigger/slower when logging in/out) and sync works again.

Run from prompt:

for /f "tokens=*" %a in ('dir /b *.dll') do regsvr32 /s %a

Remember: when running from a batchfile %a becomes %%a

So simple, yet so much used..

It’s actually a pretty big security issue, but i’m glad it exists :)
Can’t access your raid configuration anymore? Forgot your password?

Just a reminder for myself on how to rebuild degraded 3ware arrays on some of my linux machines with the cli tool.

Scenario:
The degraded drive is connected to port 2.
The drive is connected to controller 0.
Port 0 is member of unit 0.

1. Remove the drive

   tw_cli maint remove c0 p2

2. Now replace the drive
3. Enable the new drive

   tw_cli maint rescan c0

4. Assign the drive to a temporary unit

   tw_cli maint createunit c0 rspare p2

5. rebuild the array

   tw_cli maint rebuild c0 u0 p2

In our line of work a bootable stick is nothing less but essential! CD’s can be used (in fact, sometimes you have no other option as the computer won’t boot from USB) but they are slow, easily scratched, have no option to add files (unless you’re going to burn a new cd), limited in size, etc.

Bootable sticks can be used for a lot of things, e.g.

• create backups
• recover non-bootable systems
• partitioning related stuff (mbr, set active, create, remove, resize)
• offline defragmentation
• offline editting of registry
• …

But first, let’s see how to create the sticks.

MSDOS
Download this utility (originally) from HP: hp_format_usb_sp27213.exe
You’ll also need these files msdos_files_for_bootable_usb.zip

• Extract the msdos files.
• Run the utility.
• Select the device (stick).
• “Create a DOS startup disk” “using DOS system files located at:” and select the location of the msdos files.
• Start

Now just add extra files, utilities, modified config.sys or autoexec.bat and you’re off to go!

XP
I presume everybody’s familiar with WinPE/BartPE cd’s. These can be booted from usb. Refer to this site for a how-to:
http://www.911cd.net … .php?showtopic=10806

There are some disadvantages when using XP-based bootable media:

• Limited hardware support (e.g. no AHCI/sata or other harddisk controllers)
• (usb) drives connected AFTER booting won’t be recognized. They must be connected when booting, not afterwards

I recommend using Vista based media.

Vista
Bootable media based on the Vista kernel have big advantages:

• Better/more hardware support
• (usb) drives connecter AFTER booting WILL be recognized
• (best of all) Vista supports user-mode driver loading.

Example: one of my customers uses an iscsi SAN. Servers are equiped with iscsi hba’s. In case of trouble, i can boot from usb, then load the driver and all of a sudden all drives on the SAN are visible. No reboot requred. No floppy + F6 etc.

I recommend the Active Boot Disk. They come pre-loaded with utilities for checking drives, changing passwords etc too!
