• QR Codes for Files on Google Code

  - by Synetech inc.

  Hi, When you download files from Google Code now (example), in addition to the text version of the SHA1 hash, it includes a QR code of it. The device that the file was downloaded to is the one that has to hash the file. But, if it can download the file (ie, has access to the webpage), it also has access to the text version of the hash, so the QR code seems completely useless—and more work to decode when the raw text is available. How would reading the hash into a mobile phone allow you to verify the file you download to the computer? Or if you download the file to the phone, how would you use the phone to take a picture of the QR code displayed on the webpage on its own screen? Does anyone know what the point to the QR code is or how you would use it to verify the downloaded file (I don’t mean QR codes in general, but specifically in this context).

• Meinberg ntp for Windows - force more frequent updates?

  - by ana

  I have a Windows VM that has time drift problems, and left to its own devices will drift by minutes per day. I know there are issues with time on VMs, but I was hoping using the Meinberg NTP service would be successful. It works, generally, in that the time gets corrected in one big step about once every 70mins when it's at about 10mins offset. This has totally confused me as I thought NTP was meant to drift gently back towards the right time, and panic and die if the offset was more than 3 minutes. So (a) what is happening and (b) how do I make it update more regularly?

• HTTPS is not working in transparent proxy with Squid

  - by Supratik

  Hi I am using Squid proxy 3.1, all systems in the LAN connects to the internet through proxy. Direct connection is blocked using the iptables from the gateway server. There are some devices which does not have options for auto proxy or manual proxy and can only connect to the internet directly. So I enabled transparent proxy in Squid and redirected packets for port 80 and 443 to Squid proxy using iptables. Now the problem is it is working fine for HTTP port but HTTPS is not working. It is throwing "ssl_error_rx_record_too_long" error. If it is not possible through transparent proxy can you please suggest me another solution. Warm Regards Supratik

• How could I easily pack a directory to an ext4 loop partition image?

  - by Alvin Wong

  I would like to pack the content of a directory into an ext4 partition image easily, without mounting a loop device. Background: I am building a version of Android which will mount system partitions as a loop device for ARM. Though I can create those partition images by hand using loop devices, it is very troublesome. I want to use an sh script to automatically do the work, and without needing to loop mount the dd-created image and use cp -rp. The best is to directly pack the files into an image file. Question: Is there any simple command-line tools without needing loop mount and root permission that can pack files into an ext4 partition image?

• Routing only some local IPs through VPN on dd-wrt

  - by bo-inge-ostberg

  Much similar to this entry: http://serverfault.com/questions/94283/using-dd-wrt-to-connect-to-vpn-and-forward-all-traffic-of-certain-devices-through , I have set up my router with dd-wrt + OpenVPN to connect to a VPN. This works fine, and all traffic from behind the router goes through the VPN. How do I route(?) traffic in the router so that only certain IPs from the LAN will go through the VPN, while the others take the "normal" route? Is it also possible to allow traffic from certain local IPs to go ONLY through the VPN, making it impossible for them to use the regular internet connection if the VPN is down? I know this question was answered in the post I linked to, but that just doesn't seem to work for me. The routing table and rules change, but traffic still just goes through the VPN.

• Can't connect to exchange thru my smart phone

  - by Hoorayo

  We just moved Exchange server from our company to Local data center. Everything is working except mobile access. There is no problem with receiving and sending email from outlook of my laptop, but I can’t connect to exchange server from my smart phone to receive email. While I am setting up exchange account for my phone(Google) , it recognizes when I put wrong password. But it says “Unable to open connection to server” with right password and ID. Is there any option for IP address for this service when I move my server to different location? Please, help me out for any clue.

• PC case and PSU screw question....

  - by user32569

  Hi, I have maybe a funny one to ask.... To this Christmass I bought new PC. When I started to asseble it, I found that my case (Artic Cooling Silentium T11) has 12 screws for HDD, DVD etc, and 6 screws for the expansion cards. Well, first thing that surprised me was, why only 6 screws for expansion card, when case has actually 7 slots. And second, what are PSU screws supposed to some with? The PSU, Case or nothing? Becouse neighter PSU or Case had them. PSU is Evolve Storm 600W. Well, I know case and PSU are not some high end devices, but still, would it hurt them to add 1 screw for expansion cards and 4 for PSU? So, my question is, is this situation normall, or which one (Case or PSU) does normally screws come with? Thanks.

• Getting FC11 to run under VMware Server, converted from physical machine

  - by Kristian

  I have a FC11 installation that I have converted to a VMware disk image to run om my VMware Server. I converted it with qemu-img, as the VMware Converter software apparently only converts Linux hosts to VMware Infrastructure servers. The disk image boots fine (grub is loaded and boots the kernel) but it seems like the disk is not found by the kernel, and the boot process stalls. Hotplugging USB devices work (the kernel prints debug information) and I'm able to press keys (Ctrl-Alt-Delete for instance). The VMware guest OS is set to RedHat Enterprise Linux 5 (32 bit), and I have tried both the LSI Logic, LSI Logic SAS and VMware Accelerated SCSI SCSI controllers, to no avail. I'm able to boot an installer disk and get into rescue mode and mount the filesystem, so my question is, what do I need to do to the guest kernel / initrd image to make it recognize the virtual disk?

• Rewrite URL before passing to proxy Lighttpd

  - by futureelite7

  Hi, I'm trying to setup a reverse proxy in lighttpd, such that all requests (and only those requests) under /mobile/video is redirected to the / directory of a secondary web server. This is pretty easy in apache, but I can't for the life of me figure out how to do so in lighttpd. $HTTP["url"] =~ "^/wsmobile/video/" { url.rewrite-once = ( ".*" => "/test/" ) proxy.server = ( "" => ( ( "host" => "210.200.144.26", "port" => 9091 ) ) ) } I've tried using the http["url"] directive, but lighttpd simply ignore those requests and continue to pass the full url to the secondary server, which of course chokes and throws 404s. However, if I do a global rewrite then everything gets forwarded to the secondary server, which is also not what I want. How do I go about this task?

• How could I represent 1.625 by 0 or a 1 (binary digit)?

  - by pepito

  This is an excerpt from wikipedia about 'full rate' speech coding standard. Full Rate or FR or GSM-FR or GSM 06.10 was the first digital speech coding standard used in the GSM digital mobile phone system. The bit rate of the codec is 13 kbit/s, or 1.625 bits/audio sample. And this one is an excerpt from wikipedia about bit. In computing parlance, bit is the abbreviation for a single binary digit, represented by a 0 or a 1. How could I represent 1.625 by 0 or a 1? Actually, that's my lecturer's question that I could not answer. Some links to papers are more than welcome. Thanks in advance.

• How to send a popup message to unknow computer connected to my WLAN?

  - by Leandro

  Is there any way to send a popup message from a Linux systen to a "random" laptop/tablet/mobile linked to my Wireless network ? For example, if I let my WLAN open and I see a not recognized computer connected to it, is there anyway to send to that device a message ? On the other hand, if I am connected to someone else open network and they may or may not be aware that their network is open, can I send them a message warning that I am accessing their network? Probably for a completely "random" device the answer should be no. But if we restrict to laptops with Win7 or Linux SO is there any service running by default on such systems that allows one to send such popup messages ? PS: I have no practical motivation for this question. This is only a curiosity.

• Running complete Native Linux on phones that are bootloader-unlocked [on hold]

  - by james

  Since there are many phones (HTC, Samsung, LG, Nexus) today that have bootloader unlocked, I want to ask what's preventing them from running a complete native GNU/Linux. GNU/Linux has ARM port and we can run a command line GNU/Linux on top of Android by the method of chroot. So, what's preventing for existing bootloader unlocked Android phones from running a complete GNU/Linux natively? The device should get a long shelf life if it has one such port. My few thoughts.. Proprietary drivers for hardware that cannot be made to work when using a different OS. And the binary provider will never support any OS other than what the phone is shipped with. Application Interface. The interface for desktop apps doesn't fit to the mobile display with different PPI. Kernel. Since android devices use Linux kernel whose sources should be available, could the device kernel be modified to work with GNU/Linux. And any other reasons?

• Is there any SMS/MMS server for LAN environment

  - by Chau Chee Yang

  I am looking for a solution to send SMS/MMS message to mobile device from desktop or browser in LAN environment. As such, it is most probably using TCP/IP protocol to transmit request/response. The server may attach to a GSM device with SIM card attached. An server application would then start accept the request from any LAN client and convey the SMS/MMS to one or more recipients. The server may log all requests for further traffic analysis in later stage. Is there any solution that able to perform what I describe here. Please advice.

• Windows Experience Index could not be computed

  - by Alexey Ivanov

  I've upgraded recently from Windows Vista to Windows 8. When I try to rate my computer, it accesses DirectX 9 performance, then processes to DirectX 10 tests: And it gets stuck at this point. In 5–10 minutes, it shows error message: The video card is rather old: Mobile Intel 965 Express Chipset Family. I'm pretty sure it does not support DirectX 10. Why does Windows assess it with DirectX 10? And how can I make it skip DirectX 10 tests and get the system rating? The driver was installed automatically by Windows 8 from Windows Update.

• Manage MS SQL server over SSH (putty)

  - by adopilot

  There is great implementation of PuttY for Symbian S60 devices, and last versions of Nokia phones with full QWERTY keyboard offers comfort for using Putty and SSH goodies. I start wondering is there a way to access MSSQL over SSH and send T-SQL commands. I am able to connect my router which running on FreeBSD OS, also other CentOS server with MYSQL are able to me over SSH. I want to try access MS-SQL-2005 from my mobile phone, Probably this is not going to have daily use, it is just for geeky and justification to myself: why I had to buy so expensive a toy

• Wi-Fi connected but can't go to any site

  - by Michael Dy

  My Windows 7 laptop can connect to our Wi-Fi signal, I can sign in on Yahoo! Messenger, but I can't go to any site. I can access the Net on other devices. The issue started a few weeks ago, so I've been troubleshooting since then in vain. There's no virus, and I already used System Restore. In Wireless Network Connection Status, the received activity is greater than the sent activity. I turned off Windows Firewall and still no Net access. My ping tests: How do I fix this?

• What type of VPS stats should I look for?

  - by Dave

  I have a few websites that average a total of 10,000 uniques a day across my network. I also have a few mobile apps that pull xml data maybe 5,000 calls a day. My sites aren't anything major just a few wallpaper websites and few other small sites, nothing real database intensive. I currently own a dedicated server and I feel like it's overkill for my network. I'm looking into getting a Virtual Private Server (VPS). I was just wondering what kind of stats I should be looking for to support my network of sites. Thanks

• Filemaker 10 Advanced sending email via script & SMTP

  - by Sean

  We are using a windows server box to run the databases but we have found via the headers that the emails are send from the local workstation. We have moved to a new email system and have set up a local linux server to securely send email out of our network to devices that do not support new protocols and encryption. But once we set up the script in filemaker 10 advanced (the local machine os x) we set it to the ip of our local box with no authentication but it does not send out an email. It creates a connection we see in the logs on the linux box but nothing more, additionally you can start a telnet connection with no issues. We have also made sure that there are no additional issue that we can see in our firewall policies. Any ideas where we should start? Does Filemaker 10 advanced log errors anywhere because I could not find any log files.

• Virtual fiber channel HBA in Solaris

  - by Phil

  We are trying to set up some virtual Fibre Channel HBA's in Solaris. This seems to be possible with NPIV. Creating NPIV's in a Solaris global zone works fine, but passing that NPIV to a zone didn't work at all. We tried to pass the NPIV as following: # zonecfg -z zone1 'info' zonename: studentz1 [...] device: match: /devices/pci@0,0/pci8086,25f9@6/pci8086,350c@0,3/pci1077,140@4/fp@1,0:devctl allow-partition not specified allow-raw-io not specified Wat we want to do is, set up an environment for SAN exercises. We don't have a physical host per student, so we try to virtualise that in some way (Solaris zones or VMware). It should be possible to display the WWN of the virtual HBA and mount the storage presented by the disk subsystem. Any ideas to pass the NPIV to a solaris zone or to virtualise this with vmware?

• Single-port 2600 router with 2900XL switch

  - by Slava Maslennikov

  I have a setup, where the single port 2600 router is in port 0/2 in the switch, outside network is on port 0/1, and the rest (0/3-0/24) should be clients for the second network that would be managed by the 2600 router. I configured everything with two VLANs: 100 for outside (0/2-0/24), 200 for inside (0/1-0/2). 0/2 is a trunk port for the two VLANs. The issue that came about is that I can't have two VLANs on at once: software doesn't allow it. Now, I can ping the outside network devices (172.16.7.1, 172.16.7.103), and even google (8.8.8.8) from the router, but not the switch. Devices on connected get a DHCP lease properly but can't ping outside the network, just the router - 172.17.7.1 and the switch itself, 172.17.7.7. The configuration for both the router and the switch are here, as well as below. Router: rt.throom#sho run Building configuration...

• How does bridged networking work?

  - by agz

  How does bridged networking work? I have looked through the virtualbox manuals but nothing extremely technical came up (It was just a generic gloss over of the topic) How does it assign a different ip to the virtual machine but uses the same network card? Why does this different ip (I found using ip addr under linux) not show up under the "attached devices section" of my router but I can port forward to it? How come if I connect to a password protected wifi network, it does not require me to enter my password? Is this multihoming?

• Need assistance setting up Linux Router with 2 public lans

  - by user195407

  I was assigned a.b.c.10/30 (Public IP) for my router and given a.b.c.9 as the gateway. I was also assigned x.y.z.128/25 (Public IP block) for my use. I want to setup a Linux router to handle this situation. My Linux box has 3 NICs, eth0 is a.b.c.10, eth1 I have assigned x.y.z.254, eth2 is unused at present. I have eth1 connected to a network switch, and several devices connected. Let's say box A is x.y.z.129 with a gateway of x.y.z.254. I have not connected to the network yet, as it is not live. What settings do I need to make, beyond adding the 2 network definitions to the cards and having "route add default gw a.b.c.9 eth0"? I may add a private 192.168.100.0/24 lan to eth2 later.

• How can I apply a DSP to my microphone in windows?

  - by user16315

  I'd like to be able to run my microphone through arbitrary DSP filters--Mostly for compression and amplification, but also noise cancelation would be nice. I'd then like to take that output and put it back in a virtual audio device that I could use as input for skype, mumble, teamspeak, or any other VOIP program. With a program like Virtual Audio cable, I can do the 'fake devices' part but as far as I know it does not allow any kind of filtering inline. Does a program like this exist? Or some combination of programs that can be combined to accomplish this?
