• Non-OEM Biometric Software?

  - by Iszi

  Most of us with fingerprint readers and such devices probably use the software provided by the vendor, to enable biometric OS login or single sign-on functionality. However, I've recently wondered if there is any third-party software that will do the same thing. This would be similar to how you don't need the manufacturer's software to use a scanner, printer, or webcam - you just use their drivers and your choice of software. Is there anything like this for fingerprint readers or other biometric devices? Free or Open Source projects are preferred, but I'd be interested in learning about any existing solutions regardless. I personally am particularly interested in Windows-compatible software, but I'll leave the query open for any OS.

• NetFlow Storage Calculator

  - by javano

  I am planning to deploy a NetFlow server (using NfSen/NfDump) for harvesting data from Cisco devices; Are there standard calculations or guidelines I can use to calculate my server requirements, specifically I need to plan for storage. Is there a way of knowing how much data I will collect per day for example, given N flows? Lets say one device has 10k flows per day, this is typically XYZ MBs, so I can scale this up? If not, how many flows are you guys and girls recording per day, and how much data is this generating? Hopefully we can generate an estimate from everyone else's figures! P.S. If it makes a difference, I'll be collecting from <= 50 devices max (non more than 50Mbps each).

• Server 2012 R2 DNS Conditional forwarding not working reliably, possible caching issue?

  - by Matt

  I have a bit of a home lab setup with a domain controller that is acting as the DNS server for my network. For everything, it's working fine and forwards external DNS requests to my ISP. The household recently wanted to get Netflix going and it seemed a DNS option was better than a VPN to get around the region locking, so I signed up for unblock-us.com Since I have a Windows DNS server I thought I'd be clever and make use of conditional forwarders and added the Netflix domain to the list. Initially this worked well and all devices on the network could now access Netflix, however after about an hour going to the Netflix site would result in a page cannot be found. Doing an nslookup of Netflix.com from my PC resulted in it not returning any IP addresses. As a test, I deleted the Netflix domain from the DNS servers cache and things started working again - devices could get to the site again however the same thing happens again after around half an hour to an hour. Have I missed something here that's causing it to stop working?

• Symmetrix gatekeepers on Solaris 10

  - by Milner

  I have some Solaris machines that are connected to EMC Symmetrix for SAN storage. Apparently the Symm has a gatekeeper device that is used with the symmetrix CLI. We don't need the CLI, but I have these gatekeeper devices that constantly fill /var/adm/messages and the like with corrupt label errors. Is there anything I can do (short of deleting the devices on machine start) to get rid of them? Or should I just try to get our SAN guy to get the installer for the CLI? These things are getting annoying, and the devfsadmd daemon keeps rediscovering them on boot.

• Access points fighting for dominance?

  - by Phillip Oldham

  We have a small office with a large number of wireless devices (a mixture of desktop machines, laptops, and wifi-enabled phones) all working from a single Apple Airport Extreme which extends our wired network. I've added another Airport Extreme for resiliency, since we've been seeing a decrease in performance and (as far as I understand) access points can only handle a small number of clients. I set the new AP to extend the current network so that the clients weren't constantly switching between different wireless networks, however as soon as this AP was configured all the wireless devices started seeing network trouble, flicking on and off. I'm assuming that this is because both APs are reasonably strong, and the client can't decide which to use. What is the best route to follow to resolve this? What I'm aiming for is wireless resiliency; preferably having two APs share the network load, or if this isn't an option then having a primary AP with a "fail-over", should the primary go down for any reason.

• Question about Linux Device Drivers.

  - by smwikipedia

  I have just installed the Xubuntu. My box runs quite slower than before when installed with a Win7. I am wondering if I am missing some device drivers. I can use gnome-device-manager to list my devices. In the device list view, I saw several blue question mark on the left side of devices. Based on my windows experience, the question mark should indicate the device is not properly configured. Is it the same with gnome-device-manager? And most importantly, how could I know for sure whether or not the corresponding device drivers have been installed? Many thanks.

• How to get an inactive RAID device working again?

  - by Jonik

  After booting, my RAID1 device (/dev/md_d0 *) sometimes goes in some funny state and I cannot mount it. * Originally I created /dev/md0 but it has somehow changed itself into /dev/md_d0. # mount /opt mount: wrong fs type, bad option, bad superblock on /dev/md_d0, missing codepage or helper program, or other error (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) In some cases useful info is found in syslog - try dmesg | tail or so The RAID device appears to be inactive somehow: # cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md_d0 : inactive sda4[0](S) 241095104 blocks # mdadm --detail /dev/md_d0 mdadm: md device /dev/md_d0 does not appear to be active. Question is, how to make the device active again (using mdmadm, I presume)? (Other times it's alright (active) after boot, and I can mount it manually without problems. But it still won't mount automatically even though I have it in /etc/fstab: /dev/md_d0 /opt ext4 defaults 0 0 So a bonus question: what should I do to make the RAID device automatically mount at /opt at boot time?) This is an Ubuntu 9.10 workstation. Background info about my RAID setup in this question. Edit: My /etc/mdadm/mdadm.conf looks like this. I've never touched this file, at least by hand. # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired. DEVICE partitions # auto-create devices with Debian standard permissions CREATE owner=root group=disk mode=0660 auto=yes # automatically tag new arrays as belonging to the local system HOMEHOST <system> # instruct the monitoring daemon where to send mail alerts MAILADDR <my mail address> # definitions of existing MD arrays # This file was auto-generated on Wed, 27 Jan 2010 17:14:36 +0200 In /proc/partitions the last entry is md_d0 at least now, after reboot, when the device happens to be active again. (I'm not sure if it would be the same when it's inactive.) Resolution: as Jimmy Hedman suggested, I took the output of mdadm --examine --scan: ARRAY /dev/md0 level=raid1 num-devices=2 UUID=de8fbd92[...] and added it in /etc/mdadm/mdadm.conf, which seems to have fixed the main problem. After changing /etc/fstab to use /dev/md0 again (instead of /dev/md_d0), the RAID device also gets automatically mounted!

• Xen HVM guest has severe clock drift

  - by ipartola

  I am seeing a very severe clock drift on my Xen HVM VPS, rented from a hosting provider, so I don't have access to the dom0 system. I continuously run ntpd, but the clock drifts by as much as 30 seconds in 5 minutes and NTP cannot keep up. Has anyone experienced this? Here are some details: $ dmesg | grep clock [ 0.160000] Measured 347 cycles TSC warp between CPUs, turning off TSC clock. [ 0.396000] * this clock source is slow.

• How do I troubleshoot CanoScan LIDE20 on Ubuntu 9.10 in VirtualBox?

  - by kara-marfia

  This may be a VirtualBox question more than anything else. The host OS is Win7, which sees the scanner, but has no drivers for it. VirtualBox sees & recognizes the scanner as "Cannon Scan" and shows "state captured" when I hover over USB devices. Searching gives me many happy reports of this particular scanner being well supported, and that SANE should work with it immediately (also listedin the Supported Hardware List. I get "no devices available" from XSane... and I'm not sure where else I can check. I'd like to see if VirtualBox is telling the truth and find out if the USB port is actually being fed into the virtual OS. Can anyone point me in the right direction of where/how to do that in Ubuntu? Or other bright ideas. I'm starting with a little project to add some zing to my beginner linux studies - I'm sure I haven't checked some obvious things, because I don't know them yet. ;)

• Get the wireless adapter frequency-band mode in Windows 7

  - by Petr

  I have a dual-band 802.11n router operating in both frequency bands with the same SSID. My Windows 7 laptop has a dual-band wireless adapter. Is there a way to find out which frequency band is the one currently used by the client? Also, is there a way to set the preffered band? Thanks. EDIT1: The router is Linksys E4200 (V2) and I essentially want to keep the 2.4GHz band in the mixed-mode so that the legacy 802.11g devices can connect while allocating the 5.0GHz band for 802.11n devices. The laptop's adapter (Intel Centrino Ultimate-N 6300 ANG) can operate in both 802.11n modes. EDIT2: Related topic

• Configure ubuntu 12.10 to share internet through second NIC with subnetwork

  - by Dan Smith

  I have an Ubuntu 12.10 box with 2 NICs. eth0 is connected to my 192.168.1.X network, which is connected to my home router and out to the internet. I want the other interface, eth1,to support 10.0.0.x and allow devices on that network to access the internet through my ubuntu box. I do not need dhcp on the 10.0.0.x network. Here's a schematic: Internet --- home router ---- ubuntu[eth0:192.168.1.x, eth1:10.0.0.x] --- [10.0.0.x device] How do I configure the ubuntu box to share the internet with devices on that subnetwork? Thanks!

• RHEL raw device (over VMware RDM) performance issues

  - by jifa

  I'm running RHEL 5.3 over vSphere 4.0U1. I configured multiple LUNs on my NetApp (Fibre) storage, and added the RDM on two (Linux) VMs, using the Paravirtual SCSI adapter. One LUN is 100GB in size, successfully mapped to /dev/sdb on both VMs, 5 more are 500MB in size (mapped to /dev/sd{c-g}. I also created one partition per device. I have encountered two issues: First, writing directly to /dev/sdb1 gives me ~50MB/s, while any of the /dev/sd{c-g}1 gives me ~9MB/s. There is no difference in configuration of the LUNs apart from their size. I am wondering what causes this but this is not my main problem, as I would settle for 9 MB/s. I created raw devices using udev pretty straightforwardly: ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N" per device Writing to any of the new raw devices dramatically slows down performance to just over 900KB/s. Can anyone point me in a helpful direction? Thanks in advance, -- jifa

• Intel SASWT4I SAS/SATA Controller Question

  - by Joe Hopfgartner

  Hey there! I want to assemble a cheap storage sytem based on the Norco RPC-4020 Case. When searching for controllers I found this one: Intel® RAID Controller SASWT4I This is a quote form the Spec Sheet: Scalability. Supports up to 122 physical devices in SAS mode which is ideal for employing JBODs (Just a Bunch Of Disks) or up to 14 devices in RAID 0, 1, 1E/10E mode through direct connect device attachment or through expander backplane support. Does that mean I can attatch 14 SATA drives directly to the controller using SFF-8087 - 4x SATA breakout cables? That would be nice because then I can choose a mainboard that has 6 Onboard SATA and i can connect all 20 bays while only spending 155$ on the controller and like another 100$ on cables. Would that work? And why is it 14 and not 16 when there are 4 Ports? I am really confused about all the breakout/fanout/(edge-)expanding/multiplying/channel stuff...

• How to tell if you are connected to Wireless B, G or N?

  - by Raheel Khan

  I am using Windows 7 on all wired desktops and wireless laptops in my home network. I recently upgraded my Ethernet switch to Gigabit and instantly noticed an increase in throughput in wired devices. I also bought a Wireless-N WAP but with degredation in wireless file transfer speeds. I have been told that a number of reasons could affect wireless speeds including which WAP is used, how many wireless devices are connected, which security mode is used, etc. However, that remains irrelevant to my question. Each of my laptops claim to support Wireless-N but I cannot seem to figure out how to determine if the laptops are truly running Wireless-N or are connected to the WAP through some sort of mixed-mode. I do not have control of the WAP device so cannot tell what mode it is running in. Is there a way to tell which mode is being used and what the throughput is for each connected device without having access to the WAP interface?

• Bulk inserting and updating with Entity Framework (Probably a better alternative?)

  - by Dave

  I have a data set of devices, addresses, and companies that I need to import into our database, with the catch that our database may already include a specific device/address/company that is included in the new data set. If that is the case, I need to update that entry with the new information in the data set, excluding addresses. We check if an exact copy of that address exists, otherwise we make a new entry. My issue is that it is very slow to attempt to grab a device/company in EF and if it exist updated it, otherwise insert it. To fix this I tried to get all the companies, devices, and addresses and insert them into respective hashmaps, and check if the identifier of the new data exists in the hashmap. This hasn't led to any performance increases. I've included my code below. Typically I would do a batch insert, I'm not sure what I would do for a batch update though. Can someone advise a different route? var context = ObjectContextHelper.CurrentObjectContext; var oldDevices = context.Devices; var companies = context.Companies; var addresses = context.Addresses; Dictionary<string, Company> companyMap = new Dictionary<string, Company>(StringComparer.OrdinalIgnoreCase); Dictionary<string, Device> deviceMap = new Dictionary<string, Device>(StringComparer.OrdinalIgnoreCase); Dictionary<string, Address> addressMap = new Dictionary<string, Address>(StringComparer.OrdinalIgnoreCase); foreach (Company c in companies) { if (c.CompanyAccountID != null && !companyMap.ContainsKey(c.CompanyAccountID)) companyMap.Add(c.CompanyAccountID, c); } foreach (Device d in oldDevices) { if (d.SerialNumber != null && !deviceMap.ContainsKey(d.SerialNumber)) deviceMap.Add(d.SerialNumber, d); } foreach (Address a in addresses) { string identifier = GetAddressIdentifier(a); if (!addressMap.ContainsKey(identifier)) addressMap.Add(identifier, a); } foreach (DeviceData.TabsDevice device in devices) { // update a device Company tempCompany; Address tempAddress; Device currentDevice; if (deviceMap.ContainsKey(device.SerialNumber)) //update a device deviceMap.TryGetValue(device.SerialNumber, out currentDevice); else // insert a new device currentDevice = new Device(); currentDevice.SerialNumber = device.SerialNumber; currentDevice.SerialNumberTABS = device.SerialNumberTabs; currentDevice.Model = device.Model; if (device.CustomerAccountID != null && device.CustomerAccountID != "") { companyMap.TryGetValue(device.CustomerAccountID, out tempCompany); currentDevice.CustomerID = tempCompany.CompanyID; currentDevice.CustomerName = tempCompany.CompanyName; } if (companyMap.TryGetValue(device.ServicingDealerAccountID, out tempCompany)) currentDevice.CompanyID = tempCompany.CompanyID; currentDevice.StatusID = 1; currentDevice.Retries = 0; currentDevice.ControllerFamilyID = 1; if (currentDevice.EWBFrontPanelMsgOption == null) // set the Panel option to the default if it isn't set already currentDevice.EWBFrontPanelMsgOption = context.EWBFrontPanelMsgOptions.Where( i => i.OptionDescription.Contains("default")).Single(); // link the device to the existing address as long as it is actually an address if (addressMap.TryGetValue(GetAddressIdentifier(device.address), out tempAddress)) { if (GetAddressIdentifier(device.address) != "") currentDevice.Address = tempAddress; else currentDevice.Address = null; } else // insert a new Address and link the device to it (if not null) { if (GetAddressIdentifier(device.address) == "") currentDevice.Address = null; else { tempAddress = new Address(); tempAddress.Address1 = device.address.Address1; tempAddress.Address2 = device.address.Address2; tempAddress.Address3 = device.address.Address3; tempAddress.Address4 = device.address.Address4; tempAddress.City = device.address.City; tempAddress.Country = device.address.Country; tempAddress.PostalCode = device.address.PostalCode; tempAddress.State = device.address.State; addresses.AddObject(tempAddress); addressMap.Add(GetAddressIdentifier(tempAddress), tempAddress); currentDevice.Address = tempAddress; } } if (!deviceMap.ContainsKey(device.SerialNumber)) // if inserting, add to context { oldDevices.AddObject(currentDevice); deviceMap.Add(device.SerialNumber, currentDevice); } } context.SaveChanges();

• How to charge an iPhone on a Windows PC without Installaing iTunes

  - by Martin Hollingsworth

  I want to be able to charge my iPhone on my work computer, which is running Windows Server 2008 SP1 64-Bit. When I plug the iPhone in with the USB cable, it will not charge. Windows attempts to locate a driver for the device but only comes up with a generic Camera device and even if I allow that to be installed, the iPhone still does not charge. I have checked the computer's BIOS settings and did not find anything relating to power on the USB devices. I also tried this on ports at the back of the computer in addition to those on the front. The PC is a Dell Optiplex 780. As far as I can tell USB devices do not charge unless Windows has installed an appropriate driver. Since it is a work computer I do not want to install iTunes which does include a driver. I have a workaround that I will post as an answer for reference.

• Sudden loss of Wi-Fi connectivity on OS X

  - by GJ.

  Occasionally while I work, without any special provocation, I lose connectivity via Wi-Fi. Other devices connected to the same wifi network have no interruption, and the problem gets resolved once I reboot my MacBook Air, so it's definitely a local problem. Observations: The Wi-Fi symbol in the menu indicates that I'm still connected, but apps can't actually connect neither to the Internet nor to other devices in the LAN. I can't connect to an alternate Wi-Fi network (e.g. Wi-Fi tethering via iPhone). I can connect to the Internet via iPhone USB tethering but this seems to only work some of the time. Only a reboot solves the problem but a regular restart gets stuck on a grey screen with rotating wheel (after all applications have closed) and I have to do a hard reset. How should I go about troubleshooting this? It used to happen very rarely but now is becoming more frequent (approaching once every 2-3 days on average).

• Linux kernel startup problems: how to analyze?

  - by java.is.for.desktop

  Hello, everyone! After manually updating the kernel from 2.6.33 to 2.6.34 on my OpenSuse 11.2 Notebook, it stops after the message Loading drivers, configuring devices... This stop can be interrupted with Ctrl-C, but when the system enters runlevel 5, no partitions are mounted (but the root partition), many services fail to start, and other strange things are going on. No X11. NOTE: I manually updated the kernel many times before, it worked. Yes, I know, in case of NVidia, the driver has to be recompiled. The question is: How can I analyze the cause of the problem? Doing dmesg gives me soooo much output, I can't "map" it to the output which I see at startup. The output does not contain the string Loading drivers, configuring devices, or similar.

• How do I get a 300Mbps connection over 802.11n?

  - by Daniel Schaffer

  I just bought a new wireless setup, consisting of a Cisco E2000 router, Edimax 7718un USB adapter for my laptop and an Edimax 7728in PCI adapter for my HTPC (which isn't in a location I can run cat5 to). I have to stay in the 2.4GHz band because I have an iPhone and a Wii that will need to connect. I'm aware that 11g devices will drop speeds for 11n devices, but they aren't connected yet. The fastest connection I've been able to get, with the router within 5 feet of either the laptop or HTPC is 144Mbps. The router has settings for "20MHz" and "Auto (20 MHz or 40Mhz) channel width, which I've set to the "Auto" setting. I haven't been able to find anything similar for either of the Edimax adapters. This is the first I've dealt with 11n, so I'm not even sure what else could be causing a problem. How do I get up to 300Mbps, or at least a fair bit closer?

• Ethernet 802.1x client -> WiFi AP on a Raspberry Pi?

  - by Martin Janiczek

  I have an Ethernet connection that requires 802.1x authentication (TTLS, MSCHAPv2, name+password). My goal is to connect that to something that would then act as an WiFi AP, so I can use the connection on more devices (iPhone, notebook, etc.) Would it be possible/good idea to use Raspberry Pi for this purpose? Or are there better-suited devices to do this? EDIT: found some alternatives but because of low rep can't post more than two links... OpenWRT + wpa_supplicant guide Carambola - works with OpenWRT (but probably not standalone?) Hornet-UB - works with OpenWRT Asus RT-N10+ + OpenWRT how-to EDIT 2: probably going to try TP-LINK TL-WR740N. It's a classic router, but can be flashed with OpenWRT, and the price beats everything else I've seen.

• Why does my netbook have more USB controllers than ports?

  - by yodaj007

  My netbook has three USB ports, but when I look in the device manager: Five are listed. Does this matter in the least (or, why are five listed)? The reason I bring this up: See, if I know that two of the devices in the device manager don't actually have physical ports, I can disable then and up that percentage on the other three, correct? I'm constantly being told that my devices can perform faster if I connect them to a USB 2.0 port, but this netbook is less than a year old. Thanks.

• Using a second wifi router as a wireless bridge

  - by Greg-J

  I purchased a D-Link DGL-4500 to replace my aging WRT54G around a year ago, only to find it nowhere near as reliable. It's been collecting dust since. I'm wondering if there is a way to use it as a wireless bridge so I can connect it to my home network and then use it's ethernet ports to provide network access to several devices. Is this something that can be done? If not, are there devices meant for this? Any help would be appreciated.
