  • VMware: VMware ESXi Chronicles: Ops changes part 6 – Quick troubleshooting tips
  • VMware: VMware ESXi Chronicles: After you migrate, tips on working with ESXi… – I’ve recently provided a lot of information on how to migrate to ESXi, so today I thought it would be good to go over some post-migration concerns.  Here's my "top 5" list of important ESXi post-migration considerations.
  • Aggiungere drivers a ESXi 4.1 – Mi è capitato recentemente di preparare un server HP Proliant DL360 G6 per un cliente. La macchina era dotata della classica scheda onboard dual port broadcom, ed era stata comprata inoltre una scheda di rete quad-port HP NC365T, basata sul chipset Intel 82580 MAC.<br />
    <br />
    Purtroppo, nemmeno l’ultimo ESXi 4.1 u1 riconosceva la scheda con i drivers in dotazione.<br />
    <br />
    E’ stato dunque necessario procedere all’installazione dei drivers aggiuntivi, seguendo questa procedura:

  • Creating a low cost, high performance ESX cluster | SPK and Associates – As Senior Systems Integrator for SPK and Associates, a California based IT services company specializing in infrastructure management services, I recently completed an interesting project.  The goal was to create an ESX cluster for a small engineering group (about 40 users).  The cluster would be used for a wide variety of applications — software repositories, QA testing of linux appliances, databases, and potentially others as well.  Other than a gigabit network switch and some PDUs, there was no existing infrastructure in place that I could leverage.<br />
    <br />
    For under $18k in hardware, and $7k in VMWare licensing, we were able to build a 2-node VCenter cluster with full HA support.  I expect this to be able to handle upwards of 60 virtual machines, based on typical usage.

  • Rotating Log Files – O’Reilly Media – Log files grow. That's what they're there for, after all. As a systems administrator, you need to be able to control log growth. FreeBSD provides a basic log file handler, newsyslog. The newsyslog program handles standard log file rotation. The oldest logs are deleted. Each old log is renamed. Finally, the current log is moved and a new log file is created. The newsyslog program can also compress files, restart daemons, and in general handle all the routine tasks of shuffling files[…]

  • Troubleshoot Connections through the PIX and ASA – Cisco Systems – This document provides troubleshooting ideas and suggestions for when you use the Cisco ASA 5500 Series Adaptive Security Appliance (ASA) and the Cisco PIX 500 Series Security Appliance. More often than not, when applications or network sources break or are not available, firewalls (PIX or ASA) tend to be a primary target and blamed as the cause of outages. With some testing on the ASA or PIX, an administrator can determine whether or not the ASA/PIX causes the problem.

  • ASCII Paint – Enjoy drawing and viewing some crazy ascii art. Output can be in C/C++/Java style comments Assembly comments, or the million other languages that support the # – sign comments.

    Use the buttons to change what your cursor does. Hit whatever key on the keyboard you want to be drawing with.

    If you make something cool, share it! It will be added to our database of ascii art, which will become much more accessible as time goes on. Right now you can only see random Ascii Art, but there will be a voting system shortly.

  • Scapy – Scapy is a powerful interactive packet manipulation program. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, and much more. It can easily handle most classical tasks like scanning, tracerouting, probing, unit tests, attacks or network discovery (it can replace hping, 85% of nmap, arpspoof, arp-sk, arping, tcpdump, tethereal, p0f, etc.). It also performs very well at a lot of other specific tasks that most other tools can't handle, like sending invalid frames, injecting your own 802.11 frames, combining technics (VLAN hopping+ARP cache poisoning, VOIP decoding on WEP encrypted channel, …), etc.

  • Top 20+ MySQL Best Practices – Nettuts+ – Database operations often tend to be the main bottleneck for most web applications today. It's not only the DBA's (database administrators) that have to worry about these performance issues. We as programmers need to do our part by structuring tables properly, writing optimized queries and better code. Here are some MySQL optimization techniques for programmers.
  • Stacklet | Create Virtual Images On The Fly – This site will be the home of all development of the stacklet engine, a new way of creating bootable images for virtualization software such as Xen. In addition to hosting the software for creating images, the site will have pre-built images spanning various operating systems, distributions and application niches. This is a large undertaking and hopefully by opening the software we can elicit multiple contributors and contributions.
