• unexplainable packet drops with 5 ethernet NICs and low traffic on Ubuntu

  - by jon

  I'm stuck on problem where my machine started to drops packets with no sign of ANY system load or high interrupt usage after an upgrade to Ubuntu 12.04. My server is a network monitoring sensor, running Ubuntu LTS 12.04, it passively collects packets from 5 interfaces doing network intrusion type stuff. Before the upgrade I managed to collect 200+GB of packets a day while writing them to disk with around 0% packet loss depending on the day with the help of CPU affinity and NIC IRQ to CPU bindings. Now I lose a great deal of packets with none of my applications running and at very low PPS rate which a modern workstation NIC would have no trouble with. Specs: x64 Xeon 4 cores 3.2 Ghz 16 GB RAM NICs: 5 Intel Pro NICs using the e1000 driver (NAPI). [1] eth0 and eth1 are integrated NICs (in the motherboard) There are 2 other PCI-X network cards, each with 2 Ethernet ports. 3 of the interfaces are running at Gigabit Ethernet, the others are not because they're attached to hubs.

The problem still occurs with them on. # lspci -t -vv -[0000:00]-+-00.0 Intel Corporation E7520 Memory Controller Hub +-02.0-[01-03]--+-00.0-[02]----0e.0 Dell PowerEdge Expandable RAID controller 4 | \-00.2-[03]-- +-04.0-[04]-- +-05.0-[05-07]--+-00.0-[06]----07.0 Intel Corporation 82541GI Gigabit Ethernet Controller | \-00.2-[07]----08.0 Intel Corporation 82541GI Gigabit Ethernet Controller +-06.0-[08-0a]--+-00.0-[09]--+-04.0 Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) | | \-04.1 Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) | \-00.2-[0a]--+-02.0 Digium, Inc.

On the old system, if it couldn't keep up this is where the drops would be. I drop packets on multiple interfaces just about every second, usually in small increments of 2-4. I tried all these sysctl values, I'm currently using the uncommented ones. # cat /etc/sysctl.conf # high net.core.netdev_max_backlog = 3000000 net.core.rmem_max = 16000000 net.core.rmem_default = 8000000 # defaults #net.core.netdev_max_backlog = 1000 #net.core.rmem_max = 131071 #net.core.rmem_default = 163480 # moderate #net.core.netdev_max_backlog = 10000 #net.core.rmem_max = 33554432 #net.core.rmem_default = 33554432 Here's an example of an interface stats report with ethtool.

With and without, it's the same. This is what my interrupt stats looked like before the upgrade, after, with ACPI on PCI it showed multiple NICs bound to an interrupt and shared with other devices such as USB drives which I didn't like so I think i'm going to keep it with ACPI off as it's easier to designate sole purpose interrupts. Is there any advantage I would have using the default i.e. ACPI w/ PCI. ? # cat /etc/default/grub | grep CMD_LINE GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 noacpi pci=noacpi" GRUB_CMDLINE_LINUX="" # cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 0: 45 0 0 16 IO-APIC-edge timer 1: 1 0 0 7936 IO-APIC-edge i8042 2: 0 0 0 0 XT-PIC-XT-PIC cascade 6: 0 0 0 3 IO-APIC-edge floppy 8: 0 0 0 1 IO-APIC-edge rtc0 9: 0 0 0 0 IO-APIC-edge acpi 12: 0 0 0 1809 IO-APIC-edge i8042 14: 1 0 0 4498 IO-APIC-edge ata_piix 15: 0 0 0 0 IO-APIC-edge ata_piix 16: 0 0 0 0 IO-APIC-fasteoi uhci_hcd:usb2 18: 0 0 0 1350 IO-APIC-fasteoi uhci_hcd:usb4, radeon 19: 0 0 0 0 IO-APIC-fasteoi uhci_hcd:usb3 23: 0 0 0 4099 IO-APIC-fasteoi ehci_hcd:usb1 38: 0 0 0 61963 IO-APIC-fasteoi megaraid 48: 0 0 1002319 4 IO-APIC-fasteoi eth0 49: 0 0 38772 3 IO-APIC-fasteoi eth1 77: 0 0 130076 432159 IO-APIC-fasteoi eth4 78: 0 0 0 23917 IO-APIC-fasteoi eth5 82: 1329033 0 0 4 IO-APIC-fasteoi eth2 83: 0 4886525 0 6 IO-APIC-fasteoi eth3 NMI: 5 6 4 5 Non-maskable interrupts LOC: 61409 57076 64257 114764 Local timer interrupts SPU: 0 0 0 0 Spurious interrupts IWI: 0 0 0 0 IRQ work interrupts RES: 17956 25333 13436 14789 Rescheduling interrupts CAL: 22436 607 539 478 Function call interrupts TLB: 1525 1458 4600 4151 TLB shootdowns TRM: 0 0 0 0 Thermal event interrupts THR: 0 0 0 0 Threshold APIC interrupts MCE: 0 0 0 0 Machine check exceptions MCP: 16 16 16 16 Machine check polls ERR: 0 MIS: 0 Here's sample output of vmstat, showing the system.

I can't figure out why my PCI-X slots are negotiated as PCI. The network cards are all PCI-X with the exception of the integrated NICs that came with the server. In the output below it looks as if eth3 and eth2 negotiated at PCI-X speeds rather than PCI:66Mhz. Wouldn't they all drop to PCI:66Mhz? If your integrated NICs are PCI, as labeled below (eth0,eth1), then wouldn't all devices on your bus speed drop down to that slower bus speed? If not, I still don't know why only one of my NICs ( each has two ethernet ports) is labeled as PCI-X in the output below. Does that mean it is running at PCI-X speeds are is it showing that it's capable? # dmesg | grep e1000 [ 3678.349337] e1000: Intel(R) PRO/1000 Network Driver - version 7.3.21-k8-NAPI [ 3678.349342] e1000: Copyright (c) 1999-2006 Intel Corporation.

• How to Browse Without a Trace with an Ubuntu Live CD

  - by Trevor Bekolay

  No matter how diligently you clear your cache and erase your history, web browsing leaves traces on your computer. If you need keep your browsing private, then an Ubuntu Live CD is the answer. The key to this trick is that the Live CD environment runs completely in RAM, so things like your cache, cookies, and history don’t get saved to a persistent storage location. On a hard drive, even deleted files can be recovered, but once a computer is turned off the data stored in RAM is unrecoverable. In addition, since the Ubuntu Live CD environment is the same no matter what computer you use it on, there’s very little identifying information that a website can use to track you! The first step is to either burn an Ubuntu Live CD, or prepare a non-persistent Ubuntu USB flash drive. Ubuntu treats non-persistent flash drives like CDs, so files will not be written to it, but if you’re paranoid, then using a physical CD ensures that nothing gets written to a storage device. Boot up from the CD or flash drive, and choose to Run Ubuntu from the CD or flash drive if prompted (for more detailed instructions on booting from a CD or USB drive, see this article, or our guide on booting from a flash drive even if your BIOS won’t let you). Once the graphical Ubuntu environment comes up, you can click on the Firefox icon at the top of the screen to start browsing. If your browsing requires Flash, then you can install it by clicking on System at the top-left of the screen, then Administration > Synaptic Package Manager. Click on Settings at the top of the Synaptic window, and then select Repositories. Add a check in the checkbox with the label ending in “multiverse”. Click Close. Click the Reload button in the main Synaptic window. The list of available packages will reload. When they’ve reloaded, type “restricted” in the Quick search box. Right-click on ubuntu-restricted-extras and select Mark for Installation. It will note a number of other packages that will be installed. This list includes audio and video codecs, so after installing these, you should be able to play downloaded movies and songs. Click Mark to accept the installation of these other packages. Once you return to the main Synaptic window, click the Apply button and go through the dialogs to finish the installation of Flash and the other useful packages.

• Collaborate 2010: Spotlight on Oracle Content Management

  - by [email protected]

  Excitement is building for the Collaborate conference April 18th through the 22nd. Outside of the event being in Las Vegas, which for me often seems to add to the excitement, there will be a great lineup of Oracle Content Management focused sessions. In fact, there are currently over 30 content management sessions scheduled, and attendees will get to hear from customers, partners, as well as Oracle experts. Attendees should expect to hear a lot about Oracle Content Management 11g at Collaborate 2010. Roel Stalman and Andy MacMillan will kick off these discussions on Monday, April 19th as they present Oracle Content Management's product strategy and roadmap (10:45 - 11:45). Monday's lineup also includes sessions on Oracle Imaging and Process Management (I/PM) 11g and Oracle Forms Recognition (2:30 - 3:30), which were both released in January. For those customers using older versions of I/PM or Stellent IBPM, be sure not to miss the "migrating to I/PM 11g" session on Monday as well (1:15 - 2:15) as this should give you some insight into the migration process. Check out the entire list of Oracle Content Management sessions here. Another focus at Collaborate this year is to discuss the benefits of using Oracle Content Management with Oracle Applications - Oracle E-Business Suite, PeopleSoft, and Siebel - so be sure to check out these sessions too: Accelerating Accounts Payable Processes with Integrated Document Imaging(Monday, April 19th, 3:45 - 4:45)Supercharge Your Siebel Sales and Marketing with Integrated Document Management(Tuesday, April 20th, 2:00 - 3:00)Oracle Enterprise 2.0 for Oracle Applications: The Value of an Integrated E2.0 Platform(Tuesday, April 20th, 3:15 - 4:15)Comprehensive Human Resources Automation with Oracle Content Management(Wednesday, April 21st, 1:00 - 2:00) Collaborate is also the perfect opportunity to meet Oracle executives and product experts. Attendees can sign up for 1 on 1 meetings at the event, and there will be someone representing each Oracle Content Management product. These meetings are probably the best way to get your product questions answered in a face-to-face manner. It seems more and more to me that Oracle Content Management customers are viewing Collaborate as "the" conference to attend each year. I hope you have plans to attend and I will see you there.

• It’s On! Oracle Open World 2012 Opens Call for Papers is Open

  - by David Hope-Ross

  Oracle OpenWorld is among the world’s largest industry events for good reason. It offers a vast array of learning and networking opportunities in one of the planet’s great cities.  And one of the key reasons for its popularity among procurement and supply chain professionals is the prominence of presentations by customers.   If you’d like to deliver a presentation based on your experience, now is the time to submit your abstract for review by the selection panel. The competition is strong: roughly 18% of entries are accepted each year from more than 3,000 submissions. Review panels are made up of experts both internal and external to Oracle. Successful submissions often (but not exclusively) focus on customer successes, how-tos, or best practices. What’s in it for you? Recognition, for one thing. Accepted sessions are publicized in the content catalog, which goes live in mid-June, and sessions given by external speakers often prove the most popular. Plus, accepted speakers get a complimentary pass to Oracle OpenWorld with access to all sessions and networking events- that could save you up to $2,595!   Be sure designate your session for inclusion in the correct track by selecting  “APPLICATIONS: Supply Chain Management” or “APPLICATIONS: Sourcing and Procurement” from the Primary Track drop down menu.   We look forward to seeing you in San Francisco!

• Clarity Comics Comic Reader for Windows Phone 7

  Weve been really busy building all sorts custom Windows Phone 7 goodies lately.  One of the experiences weve been working on recently is a comic book reader  for WP7.  Here at Clarity we have particular individuals that are nuts about comics and codingso it was a no-brainer to knock this thing out.  Under the Covers There are a couple of components to this application that made it come together quickly.  First, as you know, WP7 runs Silverlight so we were able to leverage a bunch of silverlight assets we had hanging around from previous projects.  We were shocked to see the 80% code reuse claim was true!  Second, the application was built on the newly created Clarity Phone Framework (CP7).  This framework provides a platform that we can leverage to quickly wire up applications and get them out the door.  The framework includes gesture support, mapping controls, data visualization,  a special mvvm architecture for the phone, navigation animations, and a handful of other controls weve cooked up in our labslike voice recognition support.  (additional posts on the framework are coming soon) Third, the reading experience of the comic reader is driven by Deep Zoom.  We were pleasantly surprised to see that the windows phone 7 sdk worked nicely with Deep Zoom and the Deep Zoom composer.  We did have to add some hooks in there to get the gestures to work, but nothing too deep (no pun intended).  Unfortunately we cant release the code for this one just yet.  But rest-assured, there will be plenty more Windows Phone 7 and Silverlight goodies to come. Cheers!Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

• Wireless internet is connected to an open network but has no internet

  - by Joshua Reeder

  I just installed Ubuntu on my laptop yesterday and it connected to the wireless fine. Then I took it to school, put it on their wired connection, downloaded some stuff, and now the wireless doesn't work. At first it would detect networks, but not connect. I restarted it and now it can connect, but it acts like it doesn't have internet in the browser. Wired connection still works fine on it. I know it isn't the network because my ipad is working on the wireless connection fine. I found another solution on here switching the security settings for the wireless, but this is the apartment's wireless so they have it open, and I won't be able to mess with it at all.

• Make it simple. Make it work.

  - by Sean Feldman

  In 2010 I had an experience to work for a business that had lots of challenges. One of those challenges was luck of technical architecture and business value recognition which translated in spending enormous amount of manpower and money on creating C++ solutions for desktop client w/o using .NET to minimize “footprint” (2#) of the client application in deployment environments. This was an awkward experience, considering that C++ custom code was created from scratch to make clients talk to .NET backend while simple having .NET as a dependency would cut time to market by at least 50% (and I’m downplaying the estimate). Regardless, recent Microsoft announcement about .NET vNext has reminded me that experience and how short sighted architecture at that company was. Investment made into making C++ client that cannot be maintained internally by team due to it’s specialization in .NET have created a situation where code to maintain will be more brutal over the time and  number of developers understanding it will be going and shrinking. Not only that. The ability to go cross-platform (#3) and performance achievement gained with native compilation (#1) would be an immediate pay back. Why am I saying all this? To make a simple point to myself and remind again – when working on a product that needs to get to the market, make it simple, make it work, and then see how technology is changing and how you can adopt. Simplicity will not let you down. But a complex solution will always do.

• Reminder: Premier Support for EBS 11i ends November 2010

  - by Steven Chan

  Apps sysadmins are going to have a busy year.  If you're still running your E-Business Suite environment on the 10gR2 database, I hope that you're aware that Premier Support for 10.2 ends in July 2010.  But if you're still on Oracle E-Business Suite Release 11i version 11.5.10, the impending end of Premier Support this year on November 30, 2010 is even more important.  Support windows for Oracle E-Business Suite are listed here:Oracle Lifetime Support > "Lifetime Support Policy: Oracle Applications" (PDF)Premier Support runs for five years from a product's first release.  In the case of Oracle E-Business Suite Release 11.5.10, that window was increased to six years in recognition of the challenges that some of you face in justifying major upgrades in today's economy. Here's a graphical summary of the EBS 11.5.10's support stages:First year of Extended Support fees for EBS 11.5.10 waivedRegular readers may recall that fees for the first year of Extended Support for EBS 11.5.10 are waived.  There is nothing that customers need to do to remain fully supported other than keep your support contracts current.  Higher fees for Extended Support will start December 1, 2011 for most platforms.  This is formally documented here:Technical Support Policies > "Oracle's Technical Support Policies" (PDF)

• Fill a Flash Drive with Portable Software using Lupo PenSuite

  - by Asian Angel

  A flash drive full of portable software is helpful to have along wherever you go. The Lupo PenSuite lets you choose from three different versions to get the best fit for your everyday needs. Note: If running the full version you will need a 512 MB USB flash drive or larger. Using Lupo PenSuite The one window to watch for during the setup process is where you have the opportunity to add a specific language pack if needed. Outside of that all that you need to do is sit back and wait for the suite to be extracted. Note: Extraction times will vary based on version and extraction location. Here we browsed to our flash drive to extract it to… Once the setup process is complete locate and double click the Lupo_PenSuite.exe file. This one time window will present you the opportunity to start using the suite immediately, or go directly into the options. When the suite is active you will have a new system tray icon that operates as a start menu button. At the bottom you can monitor the remaining room on your flash drive, and use the close button to exit the suite (may display as a power button based on menu theme). A quick look at the set up inside the suite. There is a pre-configured area for organizing and storing your personal files. Prefer a classic style menu? Just select for it in the options (various tab) and enjoy a smaller streamlined look. Note: You can also change the theme for the regular menu and add a user pic. The suite provides access to your portable software and online sites. You get to enjoy the best of both as shown in the following examples. Websites will open using the suite’s portable Firefox install. VLC is ready to play your downloaded videos. The suite also has some very nice photo editing programs added in. Installing Additional Apps If one of your favorite programs is not included in the suite version, it only takes a few minutes to add it in. Go to the Additional Apps webpage, download the app(s), and extract them onto your hard-drive. Note: Link for additional apps webpage provided below. Add the extracted app(s) to the MyApps folder in the suite’s folder hierarchy. Click on ASuite in the suite’s start menu. Drag and drop the portable app’s exe file into the MyApps section in the ASuite window. Your new software’s shortcut should display as shown here. Close this window when finished. Checking the suite’s start menu will show your new software ready to be used. Conclusion If you need a good portable software collection to carry with you on a flash drive then Lupo PenSuite is definitely worth taking a look at. We tested Lupo PenSuite on XP, Vista, and Windows 7 and it works great on all three. Another popular choice is PortableApps and you can check out our Review of that too they are essentially the same thing, each is just packaged differently.

• Healthcare and Distributed Data Don't Mix

  - by [email protected]

  How many times have you heard the story?  Hard disk goes missing, USB thumb drive goes missing, laptop goes missing...Not a week goes by that we don't hear about our data going missing...  Healthcare data is a big one, but we hear about credit card data, pricing info, corporate intellectual property...  When I have spoken at Security and IT conferences part of my message is "Why do you give your users data to lose in the first place?"  I don't suggest they can't have access to it...in fact I work for the company that provides the premiere data security and desktop solutions that DO provide access.  Access isn't the issue.  'Keeping the data' is the issue.We are all human - we all make mistakes... I fault no one for having their car stolen or that they dropped a USB thumb drive. (well, except the thieves - I can certainly find some fault there)  Where I find fault is in policy (or lack thereof sometimes) that allows users to carry around private, and important, data with them.  Mr. Director of IT - It is your fault, not theirs.  Ms. CSO - Look in the mirror.It isn't like one can't find a network to access the data from.  You are on a network right now.  How many Wireless ones (wifi, mifi, cellular...) are there around you, right now?  Allowing employees to remove data from the confines of (wait for it... ) THE DATA CENTER is just plain indefensible when it isn't required.  The argument that the laptop had a password and the hard disk was encrypted is ridiculous.  An encrypted drive tells thieves that before they sell the stolen unit for $75, they should crack the encryption and ascertain what the REAL value of the laptop is... credit card info, Identity info, pricing lists, banking transactions... a veritable treasure trove of info people give away on an 'encrypted disk'.What started this latest rant on lack of data control was an article in Government Health IT that was forwarded to me by Denny Olson, an Oracle Principal Sales Consultant in Minnesota.  The full article is here, but the point was that a couple laptops went missing in a couple different cases, and.. well... no one knows where the data is, and yes - they were loaded with patient info.  What were you thinking?Obviously you can't steal data form a Sun Ray appliance... since it has no data, nor any storage to keep the data on, and Secure Global Desktop allows access from Macs, Linux and Windows client devices...  but in all cases, there is no keeping the data unless you explicitly allow for it in your policy.   Since you can get at the data securely from any network, why would you want to take personal responsibility for it?  Both Sun Rays and Secure Global Desktop are widely used in Healthcare... but clearly not widely enough.We need to do a better job of getting the message out -  Healthcare (or insert your business type here) and distributed data don't mix. Then add Hot Desking and 'follow me printing' and you have something that Clinicians (and CSOs) love.Thanks for putting up my blood pressure, Denny.

  Learning Outcomes Name different device categories Discuss the functions and structure of I/.O modules Describe the principles of Programmed I/O Describe the principles of Interrupt-driven I/O Describe the principles of DMA Discuss the evolution characteristic of I/O channels Describe different types of I/O interface Explain the principles of point-to-point and multipoint configurations Discuss the way in which a FireWire serial bus functions Discuss the principles of InfiniBand architecture External Devices An external device attaches to the computer by a link to an I/O module. The link is used to exchange control, status, and data between the I/O module and the external device. External devices can be classified into 3 categories… Human readable – e.g. video display Machine readable – e.g. magnetic disk Communications – e.g. wifi card I/O Modules An I/O module has two major functions… Interface to the processor and memory via the system bus or central switch Interface to one or more peripheral devices by tailored data links Module Functions The major functions or requirements for an I/O module fall into the following categories… Control and timing Processor communication Device communication Data buffering Error detection I/O function includes a control and timing requirement, to coordinate the flow of traffic between internal resources and external devices. Processor communication involves the following… Command decoding Data Status reporting Address recognition The I/O device must be able to perform device communication. This communication involves commands, status information, and data. An essential task of an I/O module is data buffering due to the relative slow speeds of most external devices. An I/O module is often responsible for error detection and for subsequently reporting errors to the processor. I/O Module Structure An I/O module functions to allow the processor to view a wide range of devices in a simple minded way. The I/O module may hide the details of timing, formats, and the electro mechanics of an external device so that the processor can function in terms of simple reads and write commands. An I/O channel/processor is an I/O module that takes on most of the detailed processing burden, presenting a high-level interface to the processor. There are 3 techniques are possible for I/O operations Programmed I/O Interrupt[t I/O DMA Access Programmed I/O When a processor is executing a program and encounters an instruction relating to I/O it executes that instruction by issuing a command to the appropriate I/O module. With programmed I/O, the I/O module will perform the requested action and then set the appropriate bits in the I/O status register. The I/O module takes no further actions to alert the processor. I/O Commands To execute an I/O related instruction, the processor issues an address, specifying the particular I/O module and external device, and an I/O command. There are four types of I/O commands that an I/O module may receive when it is addressed by a processor… Control – used to activate a peripheral and tell it what to do Test – Used to test various status conditions associated with an I/O module and its peripherals Read – Causes the I/O module to obtain an item of data from the peripheral and place it in an internal buffer Write – Causes the I/O module to take an item of data form the data bus and subsequently transmit that data item to the peripheral The main disadvantage of this technique is it is a time consuming process that keeps the processor busy needlessly I/O Instructions With programmed I/O there is a close correspondence between the I/O related instructions that the processor fetches from memory and the I/O commands that the processor issues to an I/O module to execute the instructions. Typically there will be many I/O devices connected through I/O modules to the system – each device is given a unique identifier or address – when the processor issues an I/O command, the command contains the address of the address of the desired device, thus each I/O module must interpret the address lines to determine if the command is for itself. When the processor, main memory and I/O share a common bus, two modes of addressing are possible… Memory mapped I/O Isolated I/O (for a detailed explanation read page 245 of book) The advantage of memory mapped I/O over isolated I/O is that it has a large repertoire of instructions that can be used, allowing more efficient programming. The disadvantage of memory mapped I/O over isolated I/O is that valuable memory address space is sued up. Interrupts driven I/O Interrupt driven I/O works as follows… The processor issues an I/O command to a module and then goes on to do some other useful work The I/O module will then interrupts the processor to request service when is is ready to exchange data with the processor The processor then executes the data transfer and then resumes its former processing Interrupt Processing The occurrence of an interrupt triggers a number of events, both in the processor hardware and in software. When an I/O device completes an I/O operations the following sequence of hardware events occurs… The device issues an interrupt signal to the processor The processor finishes execution of the current instruction before responding to the interrupt The processor tests for an interrupt – determines that there is one – and sends an acknowledgement signal to the device that issues the interrupt. The acknowledgement allows the device to remove its interrupt signal The processor now needs to prepare to transfer control to the interrupt routine. To begin, it needs to save information needed to resume the current program at the point of interrupt. The minimum information required is the status of the processor and the location of the next instruction to be executed. The processor now loads the program counter with the entry location of the interrupt-handling program that will respond to this interrupt. It also saves the values of the process registers because the Interrupt operation may modify these The interrupt handler processes the interrupt – this includes examination of status information relating to the I/O operation or other event that caused an interrupt When interrupt processing is complete, the saved register values are retrieved from the stack and restored to the registers Finally, the PSW and program counter values from the stack are restored. Design Issues Two design issues arise in implementing interrupt I/O Because there will be multiple I/O modules, how does the processor determine which device issued the interrupt? If multiple interrupts have occurred, how does the processor decide which one to process? Addressing device recognition, 4 general categories of techniques are in common use… Multiple interrupt lines Software poll Daisy chain Bus arbitration For a detailed explanation of these approaches read page 250 of the textbook. Interrupt driven I/O while more efficient than simple programmed I/O still requires the active intervention of the processor to transfer data between memory and an I/O module, and any data transfer must traverse a path through the processor. Thus is suffers from two inherent drawbacks… The I/O transfer rate is limited by the speed with which the processor can test and service a device The processor is tied up in managing an I/O transfer; a number of instructions must be executed for each I/O transfer Direct Memory Access When large volumes of data are to be moved, an efficient technique is direct memory access (DMA) DMA Function DMA involves an additional module on the system bus. The DMA module is capable of mimicking the processor and taking over control of the system from the processor. It needs to do this to transfer data to and from memory over the system bus. DMA must the bus only when the processor does not need it, or it must force the processor to suspend operation temporarily (most common – referred to as cycle stealing). When the processor wishes to read or write a block of data, it issues a command to the DMA module by sending to the DMA module the following information… Whether a read or write is requested using the read or write control line between the processor and the DMA module The address of the I/O device involved, communicated on the data lines The starting location in memory to read from or write to, communicated on the data lines and stored by the DMA module in its address register The number of words to be read or written, communicated via the data lines and stored in the data count register The processor then continues with other work, it delegates the I/O operation to the DMA module which transfers the entire block of data, one word at a time, directly to or from memory without going through the processor. When the transfer is complete, the DMA module sends an interrupt signal to the processor, this the processor is involved only at the beginning and end of the transfer. I/O Channels and Processors Characteristics of I/O Channels As one proceeds along the evolutionary path, more and more of the I/O function is performed without CPU involvement. The I/O channel represents an extension of the DMA concept. An I/O channel ahs the ability to execute I/O instructions, which gives it complete control over I/O operations. In a computer system with such devices, the CPU does not execute I/O instructions – such instructions are stored in main memory to be executed by a special purpose processor in the I/O channel itself. Two types of I/O channels are common A selector channel controls multiple high-speed devices. A multiplexor channel can handle I/O with multiple characters as fast as possible to multiple devices. The external interface: FireWire and InfiniBand Types of Interfaces One major characteristic of the interface is whether it is serial or parallel parallel interface – there are multiple lines connecting the I/O module and the peripheral, and multiple bits are transferred simultaneously serial interface – there is only one line used to transmit data, and bits must be transmitted one at a time With new generation serial interfaces, parallel interfaces are becoming less common. In either case, the I/O module must engage in a dialogue with the peripheral. In general terms the dialog may look as follows… The I/O module sends a control signal requesting permission to send data The peripheral acknowledges the request The I/O module transfers data The peripheral acknowledges receipt of data For a detailed explanation of FireWire and InfiniBand technology read page 264 – 270 of the textbook

• What tool can record multiple parallel stream to files of defined size?

  - by Hauke

  I would like to record record multiple audio web streams like this one in parallel to an mp3 or wma file for a duration of several days. I would like to be able to limit the file size or the duration stored in each file. The tool can be for any operating system. I do not need anything fancy like song recognition, metadata or silence detection. I haven't been able to find such a piece of software so far. Example: Tap channel "News" results in: News-090902-0000-0100.mp3, News-090902-0100-0200.mp3, etc... Who knows what tool can do this? It can be commercial software.

• mythbuntu 12 - lirc device doesn't appear to even exist

  - by FrustratedWithFormsDesigner

  I'm trying to get a new installation of Mythbuntu working. So far, everything is OK except the remote. The sensor for the remote is on my Hauppauge WinTV HVR 1250. First I tried to run irw to see what was being picked up by the sensor: $ irw connect: No such file or directory Then trying to run lircd gives: $ lircd start$ lircd start lircd: can't open or create /var/run/lirc/lircd.pid I look for any lirc devices and find there are none: $ ls /dev/li* ls: cannot access /dev/li*: No such file or directory Just to be sure, I check in /proc/bus/input/devices, which shows me two powerbuttons (not sure why), kbd and mouse dev, and the audio devs. Nothing for the IR receiver on the tuner card (which I thought was strange because shouldn't the tuner show up here?). $ cat /proc/bus/input/devices I: Bus=0019 Vendor=0000 Product=0001 Version=0000 N: Name="Power Button" P: Phys=PNP0C0C/button/input0 S: Sysfs=/devices/LNXSYSTM:00/device:00/PNP0C0C:00/input/input0 U: Uniq= H: Handlers=kbd event0 B: PROP=0 B: EV=3 B: KEY=10000000000000 0 I: Bus=0019 Vendor=0000 Product=0001 Version=0000 N: Name="Power Button" P: Phys=LNXPWRBN/button/input0 S: Sysfs=/devices/LNXSYSTM:00/LNXPWRBN:00/input/input1 U: Uniq= H: Handlers=kbd event1 B: PROP=0 B: EV=3 B: KEY=10000000000000 0 I: Bus=0003 Vendor=099a Product=7202 Version=0111 N: Name="Wireless Keyboard/Mouse" P: Phys=usb-0000:00:10.1-2/input0 S: Sysfs=/devices/pci0000:00/0000:00:10.1/usb8/8-2/8-2:1.0/input/input2 U: Uniq= H: Handlers=sysrq kbd event2 B: PROP=0 B: EV=120013 B: KEY=1000000000007 ff9f207ac14057ff febeffdfffefffff fffffffffffffffe B: MSC=10 B: LED=7 I: Bus=0003 Vendor=099a Product=7202 Version=0111 N: Name="Wireless Keyboard/Mouse" P: Phys=usb-0000:00:10.1-2/input1 S: Sysfs=/devices/pci0000:00/0000:00:10.1/usb8/8-2/8-2:1.1/input/input3 U: Uniq= H: Handlers=kbd mouse0 event3 B: PROP=0 B: EV=1f B: KEY=4837fff072ff32d bf54444600000000 70001 20c100b17c000 267bfad9415fed 9e168000004400 10000002 B: REL=143 B: ABS=100000000 B: MSC=10 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HD-Audio Generic Line" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:14.2/sound/card0/input4 U: Uniq= H: Handlers=event4 B: PROP=0 B: EV=21 B: SW=2000 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HD-Audio Generic Front Mic" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:14.2/sound/card0/input5 U: Uniq= H: Handlers=event5 B: PROP=0 B: EV=21 B: SW=10 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HD-Audio Generic Rear Mic" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:14.2/sound/card0/input6 U: Uniq= H: Handlers=event6 B: PROP=0 B: EV=21 B: SW=10 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HD-Audio Generic Front Headphone" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:14.2/sound/card0/input7 U: Uniq= H: Handlers=event7 B: PROP=0 B: EV=21 B: SW=4 I: Bus=0000 Vendor=0000 Product=0000 Version=0000 N: Name="HD-Audio Generic Line-Out" P: Phys=ALSA S: Sysfs=/devices/pci0000:00/0000:00:14.2/sound/card0/input8 U: Uniq= H: Handlers=event8 B: PROP=0 B: EV=21 B: SW=40 According to dmesg, the driver was registered, but it doesn't look like any devices was associated with the driver: $ dmesg | grep irc [ 10.631162] lirc_dev: IR Remote Control driver registered, major 249 So far, I've seen a number of forum pages suggesting that I use some trick to create a link between /dev/lirc and some other device that is the REAL IR sensor, like /dev/event5, but those cases assume that the real device is shown from /proc/bus/input/devices, and I don't see any such device there. Any suggestions on how to fix or further diagnose this?

• Is this simple XOR encrypted communication absolutely secure?

  - by user3123061

  Say Alice have 4GB USB flash memory and Peter also have 4GB USB flash memory. They once meet and save on both of memories two files named alice_to_peter.key (2GB) and peter_to_alice.key (2GB) which is randomly generated bits. Then they never meet again and communicate electronicaly. Alice also maintains variable called alice_pointer and Peter maintains variable called peter_pointer which is both initially set to zero. Then when Alice needs to send message to Peter they do: encrypted_message_to_peter[n] = message_to_peter[n] XOR alice_to_peter.key[alice_pointer + n] Where n i n-th byte of message. Then alice_pointer is attached at begining of the encrypted message and (alice_pointer + encrypted message) is sent to Peter and then alice_pointer is incremented by length of message (and for maximum security can be used part of key erased) Peter receives encrypted_message, reads alice_pointer stored at beginning of message and do this: message_to_peter[n] = encrypted_message_to_peter[n] XOR alice_to_peter.key[alice_pointer + n] And for maximum security after reading of message also erases used part of key. - EDIT: In fact this step with this simple algorithm (without integrity check and authentication) decreases security, see Paulo Ebermann post below. When Peter needs to send message to Alice they do analogical steps with peter_to_alice.key and with peter_pointer. With this trivial schema they can send for next 50 years each day 2GB / (50 * 365) = cca 115kB of encrypted data in both directions. If they need more data to send, they simple use larger memory for keys for example with today 2TB harddiscs (1TB keys) is possible to exchange next 50years 60MB/day ! (thats practicaly lots of data for example with using compression its more than hour of high quality voice communication) It Seems to me there is no way for attacker to read encrypted message without keys even if they have infinitely fast computer. because even with infinitely fast computer with brute force they get ever possible message that can fit to length of message, but this is astronomical amount of messages and attacker dont know which of them is actual message. I am right? Is this communication schema really absolutely secure? And if its secure, has this communication method its own name? (I mean XOR encryption is well-known, but whats name of this concrete practical application with use large memories at both communication sides for keys? I am humbly expecting that this application has been invented someone before me :-) ) Note: If its absolutely secure then its amazing because with today low cost large memories it is practicaly much cheeper way of secure communication than expensive quantum cryptography and with equivalent security! EDIT: I think it will be more and more practical in future with lower a lower cost of memories. It can solve secure communication forever. Today you have no certainty if someone succesfuly atack to existing ciphers one year later and make its often expensive implementations unsecure. In many cases before comunication exist step where communicating sides meets personaly, thats time to generate large keys. I think its perfect for military communication for example for communication with submarines which can have installed harddrive with large keys and military central can have harddrive for each submarine they have. It can be also practical in everyday life for example for control your bank account because when you create your account you meet with bank etc.

• Solaris: What comes next?

  - by alanc

  As you probably know by now, a few months ago, we released Solaris 11 after years of development. That of course means we now need to figure out what comes next - if Solaris 11 is “The First Cloud OS”, then what do we need to make future releases of Solaris be, to be modern and competitive when they're released? So we've been having planning and brainstorming meetings, and I've captured some notes here from just one of those we held a couple weeks ago with a number of the Silicon Valley based engineers. Now before someone sees an idea here and calls their product rep wanting to know what's up, please be warned what follows are rough ideas, and as I'll discuss later, none of them have any committment, schedule, working code, or even plan for integration in any possible future product at this time. (Please don't make me force you to read the full Oracle future product disclaimer here, you should know it by heart already from the front of every Oracle product slide deck.) To start with, we did some background research, looking at ideas from other Oracle groups, and competitive OS'es. We examined what was hot in the technology arena and where the interesting startups were heading. We then looked at Solaris to see where we could apply those ideas. Making Network Admins into Socially Networking Admins We all know an admin who has grumbled about being the only one stuck late at work to fix a problem on the server, or having to work the weekend alone to do scheduled maintenance. But admins are humans (at least most are), and crave companionship and community with their fellow humans. And even when they're alone in the server room, they're never far from a network connection, allowing access to the wide world of wonders on the Internet. Our solution here is not building a new social network - there's enough of those already, and Oracle even has its own Oracle Mix social network already. What we proposed is integrating Solaris features to help engage our system admins with these social networks, building community and bringing them recognition in the workplace, using achievement recognition systems as found in many popular gaming platforms. For instance, if you had a Facebook account, and a group of admin friends there, you could register it with our Social Network Utility For Facebook, and then your friends might see: Alan earned the achievement Critically Patched (April 2012) for patching all his servers. Matt is only at 50% - encourage him to complete this achievement today! To avoid any undue risk of advertising who has unpatched servers that are easier targets for hackers to break into, this information would be tightly protected via Facebook's world-renowned privacy settings to avoid it falling into the wrong hands. A related form of gamification we considered was replacing simple certfications with role-playing-game-style Experience Levels. Instead of just knowing an admin passed a test establishing a given level of competency, these would provide recruiters with a more detailed level of how much real-world experience an admin has. Achievements such as the one above would feed into it, but larger numbers of experience points would be gained by tougher or more critical tasks - such as recovering a down system, or migrating a service to a new platform. (As long as it was an Oracle platform of course - migrating to an HP or IBM platform would cause the admin to lose points with us.) Unfortunately, we couldn't figure out a good way to prevent (if you will) “gaming” the system. For instance, a disgruntled admin might decide to start ignoring warnings from FMA that a part is beginning to fail or skip preventative maintenance, in the hopes that they'd cause a catastrophic failure to earn more points for bolstering their resume as they look for a job elsewhere, and not worrying about the effect on your business of a mission critical server going down. More Z's for ZFS Our suggested new feature for ZFS was inspired by the worlds most successful Z-startup of all time: Zynga. Using the Social Network Utility For Facebook described above, we'd tie it in with ZFS monitoring to help you out when you find yourself in a jam needing more disk space than you have, and can't wait a month to get a purchase order through channels to buy more. Instead with the click of a button you could post to your group: Alan can't find any space in his server farm! Can you help? Friends could loan you some space on their connected servers for a few weeks, knowing that you'd return the favor when needed. ZFS would create a new filesystem for your use on their system, and securely share it with your system using Kerberized NFS. If none of your friends have space, then you could buy temporary use space in small increments at affordable rates right there in Facebook, using your Facebook credits, and then file an expense report later, after the urgent need has passed. Universal Single Sign On One thing all the engineers agreed on was that we still had far too many "Single" sign ons to deal with in our daily work. On the web, every web site used to have its own password database, forcing us to hope we could remember what login name was still available on each site when we signed up, and which unique password we came up with to avoid having to disclose our other passwords to a new site. In recent years, the web services world has finally been reducing the number of logins we have to manage, with many services allowing you to login using your identity from Google, Twitter or Facebook. So we proposed following their lead, introducing PAM modules for web services - no more would you have to type in whatever login name IT assigned and try to remember the password you chose the last time password aging forced you to change it - you'd simply choose which web service you wanted to authenticate against, and would login to your Solaris account upon reciept of a cookie from their identity service. Pinning notes to the cloud We also all noted that we all have our own pile of notes we keep in our daily work - in text files in our home directory, in notebooks we carry around, on white boards in offices and common areas, on sticky notes on our monitors, or on scraps of paper pinned to our bulletin boards. The contents of the notes vary, some are things just for us, some are useful for our groups, some we would share with the world. For instance, when our group moved to a new building a couple years ago, we had a white board in the hallway listing all the NIS & DNS servers, subnets, and other network configuration information we needed to set up our Solaris machines after the move. Similarly, as Solaris 11 was finishing and we were all learning the new network configuration commands, we shared notes in wikis and e-mails with our fellow engineers. Users may also remember one of the popular features of Sun's old BigAdmin site was a section for sharing scripts and tips such as these. Meanwhile, the online "pin board" at Pinterest is taking the web by storm. So we thought, why not mash those up to solve this problem? We proposed a new BigAddPin site where users could “pin” notes, command snippets, configuration information, and so on. For instance, once they had worked out the ideal Automated Installation manifest for their app server, they could pin it up to share with the rest of their group, or choose to make it public as an example for the world. Localized data, such as our group's notes on the servers for our subnet, could be shared only to users connecting from that subnet. And notes that they didn't want others to see at all could be marked private, such as the list of phone numbers to call for late night pizza delivery to the machine room, the birthdays and anniversaries they can never remember but would be sleeping on the couch if they forgot, or the list of automatically generated completely random, impossible to remember root passwords to all their servers. For greater integration with Solaris, we'd put support right into the command shells — redirect output to a pinned note, set your path to include pinned notes as scripts you can run, or bring up your recent shell history and pin a set of commands to save for the next time you need to remember how to do that operation. Location service for Solaris servers A longer term plan would involve convincing the hardware design groups to put GPS locators with wireless transmitters in future server designs. This would help both admins and service personnel trying to find servers in todays massive data centers, and could feed into location presence apps to help show potential customers that while they may not see many Solaris machines on the desktop any more, they are all around. For instance, while walking down Wall Street it might show “There are over 2000 Solaris computers in this block.” [Note: this proposal was made before the recent media coverage of a location service aggregrator app with less noble intentions, and in hindsight, we failed to consider what happens when such data similarly falls into the wrong hands. We certainly wouldn't want our app to be misinterpreted as “There are over $20 million dollars of SPARC servers in this building, waiting for you to steal them.” so it's probably best it was rejected.] Harnessing the power of the GPU for Security Most modern OS'es make use of the widespread availability of high powered GPU hardware in today's computers, with desktop environments requiring 3-D graphics acceleration, whether in Ubuntu Unity, GNOME Shell on Fedora, or Aero Glass on Windows, but we haven't yet made Solaris fully take advantage of this, beyond our basic offering of Compiz on the desktop. Meanwhile, more businesses are interested in increasing security by using biometric authentication, but must also comply with laws in many countries preventing discrimination against employees with physical limations such as missing eyes or fingers, not to mention the lost productivity when employees can't login due to tinted contacts throwing off a retina scan or a paper cut changing their fingerprint appearance until it heals. Fortunately, the two groups considering these problems put their heads together and found a common solution, using 3D technology to enable authentication using the one body part all users are guaranteed to have - pam_phrenology.so, a new PAM module that uses an array USB attached web cams (or just one if the user is willing to spin their chair during login) to take pictures of the users head from all angles, create a 3D model and compare it to the one in the authentication database. While Mythbusters has shown how easy it can be to fool common fingerprint scanners, we have not yet seen any evidence that people can impersonate the shape of another user's cranium, no matter how long they spend beating their head against the wall to reshape it. This could possibly be extended to group users, using modern versions of some of the older phrenological studies, such as giving all users with long grey beards access to the System Architect role, or automatically placing users with pointy spikes in their hair into an easy use mode. Unfortunately, there are still some unsolved technical challenges we haven't figured out how to overcome. Currently, a visit to the hair salon causes your existing authentication to expire, and some users have found that shaving their heads is the only way to avoid bad hair days becoming bad login days. Reaction to these ideas After gathering all our notes on these ideas from the engineering brainstorming meeting, we took them in to present to our management. Unfortunately, most of their reaction cannot be printed here, and they chose not to accept any of these ideas as they were, but they did have some feedback for us to consider as they sent us back to the drawing board. They strongly suggested our ideas would be better presented if we weren't trying to decipher ink blotches that had been smeared by the condensation when we put our pint glasses on the napkins we were taking notes on, and to that end let us know they would not be approving any more engineering offsites in Irish themed pubs on the Friday of a Saint Patrick's Day weekend. (Hopefully they mean that situation specifically and aren't going to deny the funding for travel to this year's X.Org Developer's Conference just because it happens to be in Bavaria and ending on the Friday of the weekend Oktoberfest starts.) They recommended our research techniques could be improved over just sitting around reading blogs and checking our Facebook, Twitter, and Pinterest accounts, such as considering input from alternate viewpoints on topics such as gamification. They also mentioned that Oracle hadn't fully adopted some of Sun's common practices and we might have to try harder to get those to be accepted now that we are one unified company. So as I said at the beginning, don't pester your sales rep just yet for any of these, since they didn't get approved, but if you have better ideas, pass them on and maybe they'll get into our next batch of planning.

• LSI SAS 9240-8i on Ubuntu 12.04 Hangs on Modprobe

  - by Francois Stark

  I used the LSI 9240-8i card on a smaller Intel motherboard with no problems in Ubuntu, with ZFS. However, we rebuilt the server to allow for more disks, using the ASROCK X79 Extreme 11 motherboard. It has 7 PCIe slots, and a LSI 2008 on-board. At first I thought the LSI 9240, when plugged in to PCIe, clashed with the on-board LSI 2008. Every time I plugged in the LSI 9240, modprobe would hang. Then I completely disabled the on-board LSI 2008, and the problem persisted. Last night it booted perfectly ONCE - all LSI cards and connected disks visible... However, all subsequent reboots failed. Both LSI cards' bios scans appear and they both see the disks connected to them, but Ubuntu modprobe hangs.
