How-to : RANCID installation on openSUSE 11.4 “Celadon”

-

RANCID is a great automation tool which allows you to collect configuration from network devices and store in repository with version control (CVS or SVN). In this article I will show you how to install RANCID and prepare to work on openSUSE 11.4 with subversion as repository for configs.

Having repository with network devices configuration might be also part of disaster recovery planning as in case of failure it will be easy to pull recent configuration from repository and apply on replacement router or switch.

To demonstrate commands I’m using copy&paste from PuTTY while executing step-by-step what is described in this article.

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.

Tips & tricks : Detect your public IP using telnet

-

If you need to identify your public IP and have no possibility to run web browser of any kind you can use telnet.

In order to identify public IPv4:

telnet v4address.com

In order to identify public IPv6:

telnet v6address.com

Once connection is established autoresponder will show your public IP address:

This is the telnet autoresponder at v6address.com.
You have connected over IPv4.
Your IP address is 5.10.15.20

This might be helpful when using console on some *NIX systems or on the routers.

Windows Registry : Autologon in Windows XP

-

Again one of those things which I forget when is needed. Autologon in Windows XP. Funny enough is the fact that each time I’m looking for this information is when I want to prevent Windows XP from auto logon and trying to disable that in registry using remote access from Registry Editor.

Fortunately Microsoft prepared full detailed description, so now I can write down in my scratchpad for future reference instead of using Google each time I need that 😀
