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.

A Visual Git Reference – This page gives brief, visual reference for the most common commands in git. Once you know a bit about how git works, this site may solidify your understanding.
SSH_VPN – Community Help Wiki – This page discusses using SSH to set up SSH-based point to point connections, which can then be used to create routes that create virtual private networks. Note that using SSH in this fashion is not the "best" way to create a permanent, stable VPN. Notably, SSH uses TCP, and TCP over TCP can provide abysmal performance under pathological conditions.
VPN over SSH – This how-to is intended to cover the details of how to establish a VPN (Virtual Private Network) over a SSH connection. Starting with open-ssh 4.3, you can now use a ssh connection to set up a VPN. This is technically termed "layer-3 IP-in-SSH tunnelling" and is not using ssh to port forward (ssh -L ) or create a dynamic "application level" forwarding (SOCKS) (ssh -D ). Rather a VPN is established using a SSH connection to create a virtual interface, tun0. Advantages : IMO, this technique is easier to set up then openvpn, especially if you are using a single client. Works with most Linux distributions without the need to install any additional software on the clients. The server only needs openssh-server. This protocol uses udp to transmit tunneled tcp connections resulting in a more stable connection compared with port forwarding (using ssh with the -L or -D options). Disadvantages : As of yet I do not know of a windows client which will use this protocol. If you are needing to set up a VPN with numerous clients I would use openvpn. Although there are several "how-to's" on the web, most of them assume you know something about networking and routing. This page attempts to explain some of the "missing details".

check_jvm – Nagios Exchange – JvmInspector is standalone tool + Nagios wrapper plugin (check_jvm) that dumps various properties from locally running JVMs. This information includes: * Heap & non-heap memory * Running threads * Loaded classes * Running java version, paths & arguments * On App servers only: Container server name & total active sessions (tested & supported app servers are tomcat5+ and jboss4+) JvmInspector doesn't need local or remote JMX network socket. It directly attaches to JVM's PerfData, so it MUST be started with the same USERid as the target JVM!
Raspberry Pi VPN Gateway – Netflix finally arrived in Germany, but guess what? It's library is heavily limited in comparision to the US one and if you like TV series as much as I do, you don't want to wait until they eventually release it year(s) later for us german users. Maybe you've heard recently of Anonabox — a small device with two ethernet ports that you can plug in front of your router and everything behind the device is routed through Tor (side note: turned out to be a scam and got pulled from Kickstarter in the end). However, it made me come up with an idea: Instead of having a Tor-box, I want a VPN-box that is connected to my PrivateInternetAccess VPN. If I'm in need of a VPN connection I just switch the WiFi network and I'm good to go. This way I can easily watch US content from Netflix as well as unblock location restricted content like YouTube, even with my iPhone or Xbox[…]
My Tmux Setup on unwiredcouch.com – I've been using tmux as my main terminal multiplexer for about 3 years now and have refined my configuration over time to fit my daily workflow. Which is usually a mix of writing code, chef recipes, remote login into different servers and various shell tasks. This is a flexible setup that doesn't concentrate too much on doing a specific thing or replacing an IDE inside of tmux.
