Config snippets : Setting NTP server on Cisco IOS device

-

Quick config snippet to setup external NTP server to synchronize time on Cisco IOS router.

labisr-01(config)#ip name-server 4.2.2.2
labisr-01(config)#ntp server 0.europe.pool.ntp.org
Translating "0.europe.pool.ntp.org"...domain server (4.2.2.2) [OK]
labisr-01(config)#clock timezone GMT 0
labisr-01(config)#
Please note that first I setup nameserver on router to be able to resolve NTP server FQDN.

Once NTP server is set we can check status of it:

labisr-01#sh ntp associations

Tips & Tricks : Add Sublime Text to right-click menu in Windows

-

To make using Sublime Text 3 more convenient, you can add this to right-click context menu.

It will simplify ability to open any file and/or folder with Sublime Text right from Windows Explorer.

@echo off
SET st2Path=C:\Program Files\Sublime Text 3\sublime_text.exe

rem add it for all file types
@reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 3"         /t REG_SZ /v "" /d "Open with Sublime Text 3"   /f
@reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 3"         /t REG_EXPAND_SZ /v "Icon" /d "%st2Path%,0" /f
@reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 3\command" /t REG_SZ /v "" /d "%st2Path% \"%%1\"" /f

rem add it for folders
@reg add "HKEY_CLASSES_ROOT\Folder\shell\Open with Sublime Text 3"         /t REG_SZ /v "" /d "Open with Sublime Text 3"   /f
@reg add "HKEY_CLASSES_ROOT\Folder\shell\Open with Sublime Text 3"         /t REG_EXPAND_SZ /v "Icon" /d "%st2Path%,0" /f

How-To : Deploy VisualEditor extension for MediaWiki 1.24.2 on openSUSE 13.1 x64

-

In previous article I described how-to Deploy Parsoid on openSUSE 13.1 (which turns out to be quite a challenging task). Parsoid is component required for VisualEditor. Now it’s time for VisualEditor deployment.

Downloading VisualEditor

At the moment, when I’m doing deployment, stable version of MediaWiki is 1.24.2. VisualEditor is an extension written for certain version of MediaWiki, hence we can’t just download latest version and use it. It has to be specific release for specific MediaWiki version.

So, first we download VisualEditor for MediaWiki 1.24.2:

git clone -b REL1_24 https://github.com/wikimedia/mediawiki-extensions-VisualEditor.git
cd mediawiki-extensions-VisualEditor/
git submodule update --init

Once it’s done we need to place content of mediawiki-extensions-VisualEditor in extensions/VisualEditor folder under MediaWiki folder structure.

Finally, once we have all files in proper places it’s time to inform MediaWiki about VisualEditor.

Changes to LocalSettings.php

Changes which have to be applied to LocalSettings.php:

# VISUAL Editor
require_once("$IP/extensions/VisualEditor/VisualEditor.php");
$wgDefaultUserOptions['visualeditor-enable'] = 1;
$wgHiddenPrefs[] = 'visualeditor-enable';
$wgVisualEditorParsoidURL = 'http://localhost:8000';
$wgVisualEditorParsoidPrefix = 'localhost';
Remember to adjust Parsoid URL and Prefix accordingly to setup of your Parsoid service.

From now on you can enjoy VisualEditor until you decide to upgrade to newer version of MediaWiki.
Prior to that I would suggest to check if there is VisualEditor available for new release and test it prior to live deployments.

Games : Codes : Skyrim – finding Lydia

-

I’m a big fan of Skyrim 🙂 so, sometimes I will put some codes and clues for that game.

If for some reason you have to leave Lydia and take another person with you and then you want to bring Lydia back you can speed up that process using codes.

  • player.moveto a2c94 – will bring you to current Lydia location
  • a2c94.moveto player – will bring Lydia to your current location

You might have to split up with Lydia if you need to hire someone else temporarily like in Boethiah quest.

How-to : Introduction to Laravel : Publish Laravel Framework project on Apache 2.4

-

In previous article “How-to : Introduction to Laravel : Create a Laravel Framework project on openSUSE Leap 42.1” we’ve created Laravel project called demo-project.

However, this project is not available on web server, so we can’t open it in web browser and see it’s content.

Let’s configure Apache server to serve our demo-project.

In this article we will:

  • Place project files in appropriate folder
  • Adjust files ownership for proper publishing
  • Create configuration for Apache, so our content will be available

Let’s get to work…

Code snippets : CMD : Dump Windows Server DHCP configuration

-

If you need to capture configuration of Windows-based DHCP server for documentation or review purposes, this might be handy:

netsh -r lab-dc-01 dhcp server dump > C:\dhcp-lab-dc-01.txt

NOTE: lab-dc-01 in example command is name of the Windows server which has DHCP installed.

Example DHCP server dump from Windows Server 2008 R2 you can see here. It contains one scope for subnet 172.16.90.0/24, option for DNS and default gateway defined.
