  • Monitor Your Website in Real-Time with Apachetop – How-To Geek – As a webmaster, I’ve often wanted to be able to see real-time hits as they arrive. Sure, Google Analytics is a wonderful package for looking at trends over time, but there’s a delay of a few hours there, and you really can’t see data like requests per second or total bytes.

    This is where the apachetop utility comes in. It’s a very simple command line utility that you can use to monitor traffic real-time. It accomplishes this by parsing the apache logfiles and displaying meaningful output to the screen.

  • Ashwin Jayaprakash’s Blog: The little gem that is BusyBox (for Windows) – As a Windows user (no shame) I have, for years searched for a simple GNU-like toolkit – grep, awk, tail and other such goodies enjoyed by Linux users. Yes, there's Cygwin but it's a beast – too big and a pain to install. Sometimes, I've even resorted to starting a Linux VMWare image just to run a simple awk script to munge some log files.
  • pclouds/busybox-w32 – GitHub – Win32 native port for Busybox (latest build can bw found in the below link)

  • using mod_auth_kerb and Windows 2000/2003/2008R2 as KDC – This tutorial contains my knowledge about using Apache/mod_auh_kerb and Windows 2000/2003/2008R2 as KDC.
  • Squid kerberos authentication and ldap authorization in Active Directory « Klaubert’s Blog – The squid web cache include a authenticator for kerberos, it is simple to use, but the documentation is not very clear about how to make it work. Below some steps use by me to make Squid 3.0 Stable1 and Squid 2.6 Stable17 authenticate against Active Directory (Windows 2003 Directory Service) and also to make it make the authorization using Ldap. This setup was not used in production environment yet, so its possible to had some problems not seen by me or scalabilities issues.
  • active directory – Getting Squid to authenticate with kerberos and Windows 2008/2003/7/XP – Server Fault – This is setup with Squid 3.0, has also been tested with Squid 3.1 and should work with Squid 2.7. Your Windows user must be a member of the SQUID_USERS group in Active Directory (for this case anyway).

    On the Windows side, Windows XP and Windows 2007 have been tested against Windows 2008, and Windows XP against Windows 2003.

  • Open vSwitch – What is Open vSwitch?

    Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, RSPAN, ERSPAN, CLI, LACP, 802.1ag). In addition, it is designed to support distribution across multiple physical servers similar to VMware's vNetwork distributed vswitch or Cisco's Nexus 1000V.

  • 21 Ruby Tricks You Should Be Using In Your Own Code – 2009 Update: This post was written in early 2008 and looking back on it, there are a couple of tricks that I wouldn't recommend anymore – or to which extra warnings need to be added. I've added paragraphs like this where necessary. Enjoy! 🙂

  • [Rename Master] – JoeJoe’s freeware utilities – Rename Master is a FREE utility designed to rename multiple files with a just few clicks. Anyone that has worked with websites, file archives, or collections of music, videos, or pictures has probably spent way too much time renaming hundreds of files.

    This utility will add, remove, or replace parts of the filename with ease and also supports renaming via file properties, MP3 tags, JPEG JFIF and EXIF tags, and text files. Batch renaming that's simple to use, yet still very powerful.

  • Sending and Receiving SMS from your Linux Computer LG #164 –
  • collectl – Collectl is a light-weight performance monitoring tool capable of reporting interactively as well as logging to disk. It reports statistics on cpu, disk, infiniband, lustre, memory, network, nfs, process, quadrics, slabs and more in easy to read format.

  • Debian Squeeze, Squid, Kerberos/LDAP Authentication, Active Directory Integration And Cyfin Reporter | HowtoForge – Linux Howtos and Tutorials – This document covers setup of a Squid Proxy which will seamlessly integrate with Active Directory for authentication using Kerberos with LDAP as a backup for users not authenticated via Kerberos. Authorisation is managed by Groups in Active Directory. This is especially useful for Windows 7 clients which no longer support NTLMv2 without changing the local computer policy. It is capable of using white lists and black lists for site access and restrictions.

    Minor distribution specific changes were made on the previous CentOS script to get it working under Debian and Ubuntu. We might create one single script which will install OpenVPN on most distributions and architectures in future.<br />

  • Install and Configure OpenVPN Server on Linux | Linux.com – The VPN is very often critical to working within a company. With working from home being such a popular draw to many industries, it is still necessary to be able to access company folders and hardware that exists within the LAN. When outside of that LAN, one of the best ways to gain that access is with the help of a VPN. Many VPN solutions are costly, and/or challenging to set up and manage. Fortunately, for the open source/Linux community, there is a solution that is actually quite simple to set up, configure, and manage. OpenVPN is that solution and here you will learn how to set up the server end of that system.<br />

  • Building a mail server on Debian 6.0 – The goal of this manual is to provide you with enough knowledge to feel confident in installing and maintaing your own mail server. Of course manuals like this already exist but during my search for knowledge I always felt like they were either not updated in a while or they just skip over some of the most interesting parts assuming you know what they are talking about[…]<br />

  • My Low End VPS Server – This document describes how to setup a Debian Linux VPS to replace your standard shared hosting account.  This document started out as a bunch of scribbles on scrap paper as I built a Virtual Private Server (VPS) into a fully functioning internet server.  It was notes on how I configured the server for the various pieces of the stack.  The need for the server was identified when I wanted to migrate my cPanel Shared Hosting account at Hostgator to a low end VPS for more control and freedom to run whatever software I wanted.  It was also a good opportunity to get back into Linux system configurations and serving web content.  As a collateral benefit, but not as the main drive, I was able to save a few dollars a month in web hosting costs.

  • A TCP Proxy in Perl – good coders code, great reuse – Several weeks ago my friend Madars was in an airport in the Netherlands and he wanted to login into his server via ssh. It turned out that their public internet had only ports 80 and 443 open so he couldn't do that. He asked me if I could proxy either port 80 or 443 to his server. Surely, I had a solution. I modified the tcp proxy server that I had written for my Turn any Linux computer into SOCKS5 proxy in one command article and did:<br />
    sudo ./tcp-proxy2.pl 443 madars-server.com:22<br />

  • IPv6 Crash Course For Linux | Linux.com – […] You might be used to working with IPv4 on Linux, but like it or not IPv6 is on its way in. Roll up your sleeves, spit on your palms, and get ready to go to work because this is your crash course in actually using IPv6. It hardly hurts at all. Linux has supported it since the 2.1 kernel, so you shouldn't have to install anything. Make sure you have the ping6, ip, and ifconfig commands. […]

  • Installing Oracle11 on Debian – The main goal is to get the Oracle installer to run so you can install Oracle successfully. This application has to run within X windows. We will use vnc for that, this is not necessary, but you may (often) find you have to install Oracle remotely. And using something like vnc sure beats spending time in a noisy server room[…]

  • Openfiler 2.3 Active/Passive Cluster (heartbeat,DRBD) With … – […] Openfiler is a Linux based NAS/SAN application which can deliver storage over nfs/smb/iscsi and ftp. It has a web interface over that you can control these services. The howto is based on the Howto from Kyle Gililland. A lot of thanks to him for this.<br />
    The cluster we build will consist of two nodes replicating each other and taking over services and storage in case of emergency. Furthermore we have an Offsite Replication Server, which ideally stands in a physically different position and replicates the configurations/storage from which ever node is active. In case of emergency this Offsite Replication Server can be used to restore the cluster and to deliver the services […]
