How to fix “ldif_read_file: checksum error”
Posted on October 28, 2014

Well, in spite of you did read a banner saying “# AUTO-GENERATED FILE – DO NOT EDIT!! Use ldapmodify.” you ignored it and made some manual modifications in any of the LDIF files in /etc/ldap/slapd.d/.

Don’t worry it happened to me too :) When you need to quickly setup an openLDAP server for development it is pretty much easier to tweak these files although the recommended way is to use ldapmodify tool. But if you change the LDIF files in cn=config manually, their contents and checksums won’t match, which is not fatal, but is annoying when using tools such as slapcat:

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Mounting VirtualBox shared folders on Ubuntu Server 18.04 LTS (Bionic Beaver)

This guide will walk you through the steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest.

Prerequisites

This guide assumes that you are using the following setup:

• Oracle VM VirtualBox version 6.0.10 with Extension Pack installed
• Microsoft Windows 7 SP1 as the host OS
• A fresh install of Ubuntu Server 18.04.2 LTS as the guest OS

You could still make this guide work with other setups (possibly with some modifications to the commands and whatnot).

Terminology

• View: Also called a "template", a file that contains markup (like HTML) and optionally additional instructions on how to generate snippets of HTML, such as text interpolation, loops, conditionals, includes, and so on.
• View engine: Also called a "template library" or "templater", ie. a library that implements view functionality, and potentially also a custom language for specifying it (like Pug does).
• HTML templater: A template library that's designed specifically for generating HTML. It understands document structure and thus can provide useful advanced tools like mixins, as well as more secure output escaping (since it can determine the right escaping approach from the context in which a value is used), but it also means that the templater is not useful for anything other than HTML.
• String-based templater: A template library that implements templating logic, but that has no understanding of the content it is generating - it simply concatenates together strings, potenti

Configure Git to use a proxy

##In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:
