  • How to fix yum errors on CentOS, RHEL or Fedora – Xmodulo – Yum is a package management tool for installing, updating and removing rpm packages on RedHat-based systems. When you try to install a package with yum command, you may encounter errors for various reasons. In this post, I will describe under what situations yum errors can occur, and explain how to fix yum errors.
  • Docs/RpmRecovery – rpm – Trac – This document provides an overview of how to deal with RPM database corruption.
  • RepoCreate – yum – Trac – Sometimes you'll find you need to be able to collect a bunch of rpm packages you have together in one place and you want to make them available to your systems running yum. It is pretty easy to do.
  • Local YUM fun | Adamish | Blog – If you’re installing redhat on a machine without Internet access you may wish to setup a local YUM repository for extra bits and pieces after the main install. Add the following to /etc/yum.repos.d/local.repo. If there are any other .repo files in /etc/yum.repos.d then comment out their contents. Make sure you don’t have spaces in your baseurl.
  • How to fix yum [Errno -1] Metadata file does not match checksum › Backdrift Backdrift – I recently upgraded my local yum repository server to RHEL6. After upgrading I noticed the below error when my el5 clients would attempting to install packages from the local repo with yum.

  • How to create an RPM package – FedoraProject – This page describes in detail how to create an RPM package, and in particular, how to create a SPEC file. Unlike other RPM guides, this page explains the specifics for Fedora with links to Fedora-specific guidelines. Since it is maintained through the Fedora Wiki, it is likely to be more up-to-date than other guides. Despite the focus on Fedora, most of this document does apply to other RPM-based distributions.
  • How To Install Elasticsearch, Logstash, and Kibana 4 on CentOS 7 | DigitalOcean – In this tutorial, we will go over the installation of the Elasticsearch ELK Stack on CentOS 7—that is, Elasticsearch 1.4.4, Logstash 1.5.0, and Kibana 4. We will also show you how to configure it to gather and visualize the syslogs of your systems in a centralized location. Logstash is an open source tool for collecting, parsing, and storing logs for future use. Kibana 4 is a web interface that can be used to search and view the logs that Logstash has indexed. Both of these tools are based on Elasticsearch.

  • Step by Step Installation and Configuration of OpenLDAP as Proxy to Active Directory | haroonferoze – This guide describes how to install and configure OpenLDAP as proxy to Active Directory.
  • Integrate Active Directory and OpenLDAP | Networking content from Windows IT Pro – OpenLDAP’s proxy service can allow LDAP operations to cross the boundaries between AD and OpenLDAP deployments. To demonstrate this proxy service, we walk through the steps to make AD’s cn=Users container, which by default contains all user objects, part of an OpenLDAP directory. To produce the examples in this article, I used CentOS 4.3, OpenLDAP 2.2.13, and AD running on Windows Server 2003 R2. Later in the article, I’ll show you a limitation in the commonly deployed OpenLDAP 2.2, which you can solve by installing OpenLDAP 2.3 on CentOS 4.3.
  • Let’s Chat — Self-hosted chat for small teams – WHAT IS THIS THING? Some backstory. Way back in 2012, we didn't like any of the existing chat services out there. So we decided to write our own. Let's Chat is a persistent messaging application that runs on Node.js and MongoDB. It's designed to be easily deployable and fits well with small, intimate teams. It's free (MIT licensed) and ships with killer features such as LDAP/Kerberos authentication, a REST-like API and XMPP support. Let's Chat is a side-project of the development team at Security Compass. (A real life 10% time project!)

Recently, check_mk released its innovation version check_mk-1.2.5i2 including MK Livestatus with compatibility with Nagios Core 4. We need therefore check_mk-1.2.5i2 or higher to run check_mk with Nagios Core 4.
  • RIPS – Static Source Code Analysis For PHP Vulnerabilities – Darknet – The Darkside – […] RIPS is a tool written in PHP to find vulnerabilities using static source code analysis for PHP web applications. By tokenizing and parsing all source code files RIPS is able to transform PHP source code into a program model and to detect sensitive sinks (potentially vulnerable functions) that can be tainted by user input (influenced by a malicious user) during the program flow. Besides the structured output of found vulnerabilities RIPS also offers an integrated code audit framework for further manual analysis.[…] [via http://www.bufferoverflow.it/ ]

  • LDAP org chart | bitcube.co.uk – For centralised authentication and authorisation, LDAP is the de-facto standard. Whether in its pure form on Unix or in Active Directory guise on Windows, everyone uses it. What many people don't realise is that you can store all sorts of useful (and not so useful) information in LDAP. One field which can be useful is the "manager" attribute. One of our customers use that and so we've written a small script to graph it using the excellent Graphviz tool. It will probably need customising for specific cases, however we hope that people find it useful nonetheless. If you want to alter the output, do have a look at the record format documentation.
  • Puppet errors explained | bitcube.co.uk – Puppet is a wonderful system automation tool, however the learning curve can be a little steep. We've collected some of the errors messages and "strange" behaviour you may come across together with explanations to help overcome these hurdles and boost adoption of this fabulous tool. If you have any useful errors and explanations, please do send them in and we'll update this article.

  • DNS Load Balancing and Using Multiple Load Balancers in the Cloud – […] Load balancing in general is a complicated process, but there's some secret sauce in managing DNS along with multiple load balancers in the cloud. It requires that you draw from a few different sets of networking and “cloudy” concepts. In this second article in my best practices series (my first post covered how to use credentials within RightScale for storing sensitive or frequently used values), I'll explain how to set up load balancers to build a fault-tolerant, highly available web application in the cloud. Here's what you’ll need: Multiple A records for a host name in the DNS service of your choice Multiple load balancers to protect against failure […]
  • gdnsd – gdnsd is an Authoritative-only DNS server which does geographic (or other sorts of) balancing, redirection, weighting, and service-state-conscious failover at the DNS layer. gdnsd is written in C using libev and pthreads with a focus on high performance, low latency service. It does not offer any form of caching or recursive service, and notably does not support DNSSEC. There's a strong focus on making the code efficient, lean, and resilient. The code has a decent regression testsuite with full branch coverage on the core packet parsing and generation code, and some scripted QA tools for e.g. valgrind validation, clang-analyzer, etc. The geographically-aware features also support the emerging EDNS Client Subnet draft for receiving more-precise network location information from intermediate shared caches.

  • Centos yum 404 repository errors | Natural Order Development – […] Basically yum ran through every single mirror and got nothing but 404 errors. I thought something might have gotten broken with yum or maybe the entire Internet changed overnight to a new repository layout (not likely but it has happened before). Well a simple Google for yum 404 led to some message threads that basically said yum's caches were out of data […]
  • Avoiding reboot: Resetting USB on a Linux machine – Every now and then, some USB device misbehaves badly enough to knock out the entire interface, to the extent that the system doesn’t detect any new USB devices. Or work so well with the existing ones, for that matter. The solution for me until now was to reboot the computer. But hey, I don’t like rebooting Linux!

  • TCP Port Scanner in Bash – good coders code, great reuse – I just had this quick idea to write a tcp port scanner in bash. Bash supports the special /dev/tcp/host/port file that you can read/write. Writing to this special file makes bash open a tcp connection to host:port. If writing to the port succeeds, the port is open, else the port is closed.

  • eAccelerator – eAccelerator is a free open-source PHP accelerator & optimizer. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution. eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times.
  • Server World – Build Network Server – This site explains how to build home server connected to internet with static IP address. You need to get at least one static IP address from your ISP. Please make sure the terms of use from your ISP, and Get one or some IP addresses if possibles. It's possible to build a network server, not with static IP address but with dynamic IP address by using Dynamic DNS, though. But I don't recommend it because there are some limits. It's the best to get at least one static IP address in order to build a network server, there is no limit. To get one static IP address is not so high costs. It's easy to build network server at your home.
    This site explains how to configure a server with commands basically, not with Graphical User Interfaces.
