RFC 2795 - The Infinite Monkey Protocol Suite (IMPS)
This memo describes a protocol suite which supports an infinite number of monkeys that sit at an infinite number of typewriters in order to determine when they have either produced the entire works of William Shakespeare or a good television show. The suite includes communications and control protocols for monkeys and the organizations that interact with them.
Walking in the World of NBAR
Not many people know this, but if your Cisco router is running a recent IOS version, it comes with a built-in, application-layer packet sniffing application called Network Based Application Recognition (NBAR). This utility was originally designed for the world of Quality of Service (QoS), but is now used for many different capabilities.

Project triangle
The Project Triangle in engineering is a triangle model of project. It is a graphic aid where the three attributes show on the corners of the triangle to show opposition. It is useful to help with intentionally choosing project biases, or analyzing the goals of your project. For example: You are given the options of Fast, Good and Cheap, and told to pick any two.(Wikipedia)
Fast, reliable, cheap: pick 2? ZFS brings all! - Openomics
The call came very quickly because the crash had led to corrupted data. Our joint investigation showed that one VxFS extend --the bank was using the Veritas File System 4.1-- contained old/bad financial data mixed with correct data. The problem was believed to happen after a new VxFS extend was allocated but before its metadata was written. By default, VxFS does not zero newly-allocated extends.

RTAudio (x-msrta) interop
As much fun as it would be to reverse-engineer this codec I sadly don’t have enough sparetime for that these days, I’m no longer a student with virtually infinite amounts of sparetime like I was back in the libmimic days. I still have this passion for reverse-engineering though, and I find it great as a recreational activity in the life part of the work/life balance. So I sat down a couple of hours one late evening with a fresh cup of Yerba Mate tea and poked around with IDA, and worked out the internal API of this codec inside the appropriate binary.

Provisioning Disaster Recovery with ZFS, iSCSI and VMware
OpenSolaris, ZFS, iSCSI and VMware are a great combination for provisioning Disaster Recovery (DR) systems at exceptionally low cost. There are some fundamentally well suited features of ZFS and VMFS volumes that provide a relatively simply and very efficient recovery process for VMware hosted non-zero RPO crash consistent recovery based environments. In this weblog I will demonstrate this capability and provide some step by step howto’s for replicating a ZFS, iSCSI and VMFS VMware based environment securely over a WAN or whatever you may have to a single ESXi remote server hosting a child OpenSolaris VM which provisions ZFS and iSCSI VMFS LUN’s to the parent ESXi host.

ZFS End-to-End Data Integrity
The job of any filesystem boils down to this: when asked to read a block, it should return the same data that was previously written to that block. If it can't do that -- because the disk is offline or the data has been damaged or tampered with -- it should detect this and return an error. Incredibly, most filesystems fail this test. They depend on the underlying hardware to detect and report errors. If a disk simply returns bad data, the average filesystem won't even detect it.

Patches to improve timekeeping for RHEL kernels running under VMware.
Bug 463573 – In a virtual environment, timekeeping for RHEL 64 bit kernels can be problematic, since time is kept by counting timer interrupts for this kernel. The problem arises when the VM is descheduled for some portion of time. When the VM is rescheduled, the hypervisor needs to "catch up" delivering timer interrupts so that the kernel can determine the correct time. Until the VM is caught up, the kernel's time will be behind, causing short term divergence of the kernel's time with wallclock time. Additionally, under certain overcommitment conditions, it may not be possible for the hypervisor to fully catch up. In this case, the kernel time can fall behind over the long term.

What is that system call doing?
Faced with a system call that is taking a long time you have to understand the three possible reasons this can happen: 1-It has to do a lot of processing to achieve it's results. 2-It blocks for a long time waiting for an asynchronous event to occur. 3-It blocks for a short time but many times waiting for asynchronous events to occur. So it would be really nice to be able to see where a system call is spending all it's time.

Home Fileserver: ACPI Suspend
Considering that a fileserver at home will spend a lot (most) of its life idle, it makes sense to look at its power usage and see what steps can be taken to reduce its operational costs — i.e. power consumption. The most obvious way to reduce power consumption is to simply turn the machine off when it’s not required. However, some people may wish to leave the machine powered on and put it into low-power mode when it’s not in use. ACPI suspend state 3 seems to be the low power mode to use.

Recursive MD5 Sum Script
ARP spoofing countermeasure using arpwatch
One of the biggest threats to a computer network is a rogue system pretending to be a trusted host. Once someone has successfully impersonated another host, he can do a number of nefarious things. For example, he can intercept and log traffic destined for the real host, or lie in wait for clients to connect and begin sending the rogue host confidential information. This attack, we named it as Man In The Middle attack using ARP poisoning or spoofing.

Playing with 'sec=none' and using AUTH_NONE
AUTH_NONE is one of the least understood security flavors you can use with NFS (see nfssec(5) for more details). When you share a resource, you can specify the security flavors with 'sec'. You can also specify an anonymous uid with 'anon'. I mention that because the two interact.

HTB home
HTB is packet scheduler, written by Martin Devera (aka devik), and included in the Linux kernel. - Prioritizing ACKs
To keep the peer sending data at the maximum rate, it's important to promptly send the ACKs back. When the uplink is saturated by other connections (like a concurrent upload), all outgoing packets get delayed equally by default. Hence, a concurrent upload saturating the uplink causes the outgoing ACKs. for the download to get delayed, which causes the drop in the download throughput.

Parity Volume Set Specification 2.0
This document describes a file format for storing redundant data for a set of files. If the files in the recovery set ever get damaged (e.g. when they are transmitted or stored on a faulty disk) the client can read the damaged input files, read the (possibly damaged) PAR files, and regenerate the original input files. Of course, not all damages can be repaired, but many can. The redundant data in the PAR files is computed using Reed-Solomon codes.
QuickPar tutorial
You can use PAR2 to check whether your downloaded files were received completely and correctly and you can repair any missing or corrupt files if necessary!

HFSC Scheduling with Linux
For complex traffic shaping scenarios, hierarchical algorithms are necessary. Current versions of Linux support the algorithms HTB and HFSC. While HTB basically rearranges token bucket filter (TBF) into a hierarchical structure, thereby retaining the principal characteristics of TBF, HFSC allows proportional distribution of bandwidth as well as control and allocation of latencies. This allows for better and more efficient use of a connection for situations in which both bandwidth intensive data services and interactive services share a single network link.

Configuring an OpenSolaris 6to4 router : seblog
A common problem in enterprise networks is that many IT departments have not begun to deploy IPv6 within their supported infrastructure, but developers need IPv6 networking in order to develop and test products which support IPv6. 6to4 (defined in RFC 3056) can be a quick way to obtain IPv6 connectivity between IPv6 nodes separated by IPv4 networks such as this. The general idea is that each 6to4 site has a 6to4 router which is responsible for automatically tunneling IPv6 packets from its site to other 6to4 routers in other 6to4 sites over IPv4.

E = mc^2 Without Relativity
[astro-ph/0504486] Andrew Gould (Ohio State University). The equivalence of mass and energy is indelibly linked with relativity, both by scientists and in the popular mind. I prove that E = mc^2 by demanding momentum conservation of an object that emits two equal electromagnetic wave packets in opposite directions in its own frame. In view of this, it is somewhat puzzling that the equivalence of mass and energy was not derived well before the advent of Special Relativity. The new derivation is simpler and more transparent than Einstein's and is therefore pedagogically useful.
