  • 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

  • PHP won't run on Fedora 15

    - by George
    I have followed this exact tutorial on installing php on a Fedora 15 system. I have all the necessary packages installed with no errors. Yet the simple phpinfo() test page will show - it will show a blank page. When I try to see the source, I see it downloaded my .php file as plain text and loaded it in the browser. So I am guessing for some reason php module is not loaded in httpd. Does anyone have any idea why? P.S. I am really hoping SELinux this time has nothing to do with this!

  • Network DFS Shares Jumping Back To Root

    - by Taz
    We map several network drives to DFS locations via a logon script. Recently we've had a number of users complain of a very unusual behaviour when navigating these shares. They will be going through folders and will get 'rubber-banded' back to the root of the share. This will happen for a few minutes and then go back to behaving normally. The users are on Windows 7 and the fileshare is on Windows Server 2K8R2. Any idea what could be causing this annoying behaviour?

  • Areca 1880ix RAID hangs

    - by Dave
    Areca RAID controller ARC-1880ix-12 (firmware 1.50) hangs when on high load. My setup is: Chenbro 3U chassis Intel S5500BC mainboard Xeon 5603 CPU 16GB of RAM 12 Seagate SAS drives ST32000645SS (2 of them as hot spare, 10 as RAID10) Mellanox Infiniband HBA card This server is working as external infiniband storage for Xen VMs. When load is quite big Areca's firmware hangs - it becomes unreachable even from Areca's ethernet adapter. After resetting the server power it returns to normal operation. While Areca is hanged I can confirm that it is powered (ethernet link is active) and Infiniband HBA works Ok. Thanks in advance for any idea or suggestion where the problem might be!

  • Why would video stutter on HDMI but not on DVI?

    - by CorvT
    I've got a system running Ubuntu 12.04 with an i3 2120T CPU/GPU. When I play video through mplayer, I notice when I'm hooked up to a screen via HDMI there is a small stutter (1-2 frames) every few seconds. I don't see this happening when I connect via DVI on the same screen. Resolution and refresh rate are same for both HDMI and DVI, so I'm not sure where else the problem could be coming from. I've also tried two different screens, and different cables. I see the stutter with either HDMI-HDMI cables, or DVI-HDMI cable with DVI from the PC and HDMI into the screen. I don't see the stutter with DVI-DVI cables, or when I use HDMI-DVI cables with HDMI from the PC to DVI into the screen. I've also tried using an AMD 5XXX series card with the open source radeon driver, and saw the same problem. I then tried an nVidia GeForce 210 card with the closed source driver, and the stutter went away. To me this smells like a driver/mesa/glx issue (since the problem went away with the nvidia card/driver), but I have no idea how to track this down.

  • Finding spoofed IP address on network

    - by Jared
    I have a few IP spoof dropped messages coming out of my Sonicwall firewall, we'll call them Source A and Source B. Both of these sources have the same mac address indicating they're coming from the layer 3 switch behind my firewall. Source A has an ip within a valid subnet on my network and it shows up in the ARP table of my layer 3 switch. I was able to trace the exact location and fix the issue. Source B's ip however, is not within valid subnet on my network and it's not showing up in my layer 3 switches arp table. Any idea how I can trace the location of this device within my network? Thanks in advance.

  • Ethernet Connection Unavailable

    - by fabikw
    I'm running Ubuntu Server 12.04 on a laptop with an Intel NIC (driver e1000e). When I connect the ethernet port to the internet (college network, DHCP) it works out of the box. Now I'm trying to connect it to a networked USRP (if you want to know what it is). A friend of mine managed to do this in his laptop (running regular Ubuntu 12.04) just by setting up a new Wired connection in the Network Manager with appropriate addresses. However, when I do the same, no wired connections are available. The output of nmcli -p dev is =========================================== Status of devices =========================================== DEVICE TYPE STATE ------------------------------------------- wlan0 802-11-wireless connected eth0 802-3-ethernet unavailable but the cable is connected to the device and the device is powered up. Any idea how to solve this? UPDATE: After stopping the network-manager service, setting up the connection manually and starting the service again, it now detects the ethernet connection. However, the device still can't receive data and doesn't answer to pings. UPDATE 2: As suggested I tried using a cross over cable but the result is exactly the same. However, I found out that connecting the device to the dock (as opposed to directly to the laptop) works fine. I know that the ethernet port in the laptop works fine, because connecting to the network through it works. Is it possible that the port in the laptop doesn't support Gb Ethernet (because that's what the device requires) but the one in the dock does?

  • Explorer forgetting how to cut and paste files

    - by raimesh
    My Windows XP (SP3) machine (at work) occasionally "forgets" how to cut-and-paste files in Explorer - if I cut or copy a file then go to paste it elsewhere, the "paste" and "paste shortcut" menu items are greyed out. The keyboard shortcuts (Ctrl+X/Ctrl+C,Ctrl+V) don't work either, and neither does Drag-and-Drop - clicking and dragging a file/folder doesn't change the pointer and letting go doesn't drop the item anywhere. Restarting the explorer.exe process usually fixes the problem, but sometimes I need to do a full reboot. Note: this may be related to the following existing question, although that's Vista and it sounds like the asker has more permanent problems than I do: http://superuser.com/questions/27045/copy-paste-in-vista-explorer-broken-not-ms-vpc So, any idea what might be causing the problem and how to avoid it?

  • What payment gateways do real customers really use when given the choice?

    - by ??????
    I would like to give customers the option of paying however they can whether that be through a proper gateway (e.g. SagePay) or through something else such as PayPal, Amazon Checkout or Google Checkout. Personally I have not bought anything through the Amazon Checkout except for on Amazon.co.uk and my PayPal buys have been limited. As for Google Checkout I have no idea what that is or how it works from a consumer perspective. I understand that people buying from smaller sites are happier to pay by PayPal as they have an account already and trust PayPal. As for Amazon Payments and Google Checkout, do people actually use them if given the choice? There are a lot of people on Kindles these days, happy to buy stuff via Amazon on their Kindle. Would Amazon Payments make sense to this growing crowd? With too many payment gateways on offer it might be confusing at the checkout. Does anyone know if this is a problem for genuine customers? I also have not seen many 'pay by Amazon Payments' icons on websites (you see PayPal all the time). Does advertising the fact that you can pay by Amazon Payments increase sales, e.g. to Kindle owners that have a nebulous book-buying account that 'their other half doesn't know about'?

  • How do I fix broken installation?

    - by Daniel
    Let me start off by saying I'm dual booting 11.04 and Windows 7 on a Thinkpad T61p. The problem may have arisen when I hit the power button during normal startup. I'm fully aware how stupid this is. I don't know why I did it. I did it. Now, I can't get in to Ubuntu. Windows works fine. But when I try to start Ubuntu normally, it seems to run some checks, and does not start up. Sometimes, I see a black screen, and it tells me that it's running certain checks, and then, [ok]. Like... Battery Check Somethingorother [ok] It'll give me 1-5 of these. And then it just does nothing, and I have to turn it off. When I try to start in safe mode... I tried low graphics mode, and after going through a couple of dialogue boxes, I'm brought right back to the safe mode dialogue box. And if I hit 'resume,' a shell pushes up (still that grey on black "your computer is broken" type shell) and asks me to log in. I do, and try to run unity. It tells me something along the lines of: WARNING no DISPLAY variable set and then sets it to " :0" , which doesn't work. And then I can't do anything, really, and I have to restart. (I don't know how to do this from the command line, so I just hard reset. That command would be helpful). Does anybody have any idea how I can get Ubuntu working right again? FTP is less pleasant in Explorer than it is in Nautilus or w/e it is now.

  • Ubuntu does not recognize my built-in monitor.

    - by B3tturTh3nU
    I've recently discovered of a boot problem Ubuntu has with my laptop. I have successfully installed Ubuntu on two other computers, and I've never experienced this problem. What happens is, after the live boot CD loads, the screen goes completely blank. Although, I suspected that there was no problem booting, so I loaded with BIOS only, which worked perfectly fine. Of course, not being very proficient with this, I have no idea what needs to be done to fix the problem. I have switchable graphics cards(the ATI Mobility Radeon HD 5650, and some low-end Intel card), and an Intel i5 quad core processor. I was booting with the Ubuntu 10.10 64 bit desktop distribution. If there's any more information you need from me, please let me know. EDIT: I was able to look into this a bit more, thanks to one of the comments provided, and I have some new information. Ubuntu does seem to be able to recognize both of my graphics cards. The problem I found was that, in the Xorg.0 log, it mentions that there were "no screens found." I'm using a notebook, so the screen is built in. Does anyone know of a way to get Ubuntu to recognize the monitor?

  • Is it possible to dynamically adjust the priority of outgoing emails?

    - by davethegr8
    This is more of a theoretical question, but is it possible to dynamically, and on an ongoing basis, adjust the priority of emails in the mail queue? For example, for all mail, set it's priority (p) to 1 (meaning send immediately). If N emails in the last M share similar or identical content, adjust the priority of this email such that it's priority is in the range [0..1] so that p is equal to 1 - N/M and other email can get sent before the similar/identical stuff. Or, if you have another idea or standard what is it? Some background: Someone put a mail() call in an infinite loop... And now we have to wait for the mail queue to catch up before anyone can send or receive mail again.

  • uploading large files (mp4) to IIS 7.5 gives 500 Internal Server Error

    I made a website on which i need to be able to upload video files and it has worked for quite a while. However after a while it just stopped working and now it will give me the following IIS error message when i upload a video. Images do work (possibly due to their smaller size). I use an html form with PHP server sided script to upload. I have already set the user permissions for the entire inetpub to allow all actions for the IIS user. If you have any idea what it could be PLEASE tell me, have been trying to fix this for weeks now. Thanks in advance!

  • Parse text file on click - and then display

    - by John R
    I am thinking of a methodology for rapid retrieval of code snippets. I imagine an HTML table with a setup like this: one two ... ten one oneTwo() oneTen() two twoOne() twoTen() ... ten tenOne() tenTwo() When a user clicks a function in this HTML table, a snippet of code is shown in another div tag or perhaps a popup window (I'm open to different solutions). I want to maintain only one PHP file named utitlities.php that contains a class called 'util'. This file & class will hold all the functions referenced in the above table (it is also used on various projects and is functional code). A key idea is that I do not want to update the HTML documentation everytime I write/update a new function in utilities.php. I should be able to click a function in the table and have PHP open the utilities file, parse out the apropriate function and display it in an HTML window. Questions: 1) I will be coding this in PHP and JavaScript but am wondering if similar scripts are available (for all or part) so I don't reinvent the wheel. 2) Quick & easy Ajax suggestions appreciated too (probably will use jquery, but am rusty). 3) Methodology for parsing out the functions from the utilities.php file (I'm not to good with regex).

  • How to set up a PC which can be booted from Linux AND Windows?

    - by Martin
    Our PC was running Windows XP up to know. It has become incredibly slow and I'm considering switching to Linux (Ubuntu?!) as a fresh OS. However, there are some applications we rarely use which run only on Windows and I also want to have the possibility to easily go back to the old system, if I should find during testing linux, that anything is missing or not available. So the idea is to install Linux on a new (second) hard drive and use the existing Windows XP from a virtual machine (converted by Paragon Drive Backup) in the transition time. We have a lot of data on the PC, tens of GBs of Photos (managed by Picasa), ... My questions: What could be the best way to setup the new hard drive? (Partitions) I assume that I can not access the Linux data from Windows but I could access (read/write) windows drives from Linux? Does anyone know good tutorials for this use case? What other things might I have to consider for transition Windows-Linux?

  • How can I get the best performance for playing games?

    - by Oli
    I've been playing a couple of Wine-games today and decided to switch to metacity to see what the performance difference was like. If you've never done it before, you just run metacity --replace but don't do that if you use Unity! Anyway, surprise surprise it was like playing on a dedicated Windows gaming machine. Playing under metacity today was bliss. Much higher framerates and just a fluidity that you'd expect from a native game. I'm not sure I can go back. Switching to metacity is no hardship but I wonder if there's anything else in the WM landscape that I should try out. I'm essentially looking for suggestions for the best way to play games. Mix up WMs, dedicated X sessions, whatever... As long as it makes Wine games run faster. Small print One process per answer (eg: New X session + OpenBox) We should probably land on a benchmark so we can show percentage improvement over a stock Compiz desktop. I'm open to suggestions in the comments. If people could test it and submit their how much it improves things for them in the comments, that would give others a good idea of if it's worth the pain.

  • How to determine what program send the packet recorded in Wireshark?

    - by Tono Nam
    I was taking some tutorials on Wireshark in order to analyze the packets sent and received when talking to a web server for purposes of learning. When I start listening/recording packets in Wireshark, there where so many packages being recorded (700 packages per minute). Is it normal to have that much traffic if I have all the programs that will cause traffic such as all browsers, log me in, dropbox, goto meeting, etc., closed? In order to try to solve the problem I am analyzing random packets. Take for instance this filter: I just selected a random IP: 74.125.130.99. So how can I know from what program those packets where created? Also how can I get more info about that communication bwtween my computer (192.168.0.139) and that server (74.125.130.99)? I just selected a random IP from the Wireshark capture. There are also other IPs that I have no idea why they are communicating with my computer. How can I figure that out?

  • How to get started in the development industry? [closed]

    - by Peter Fren
    My life is coding. I was born in 1982 and my first computer was an amiga. I started learning Amiga BASIC. To cut a long story short, I know many things about several programming languages. Being unemployed(I achieved the german abitur, should be similar to a high school degree and I studied a few semesters of mechanical engineering in 2002(I learned JAVA back then)) I have no idea how to use this ability. I have never done commissional work, every task I solved was based on my own wishes and desires. I do not know how to write a FSD or PRD or put it into code. So the question is, why should anyone hire me? I specialized in kinect development but all jobs I applied for on odesk and similar were awarded to others without me knowing why. I don't know what I should do with my skills professionally. What do you suggest? As this board has weird rules, tell me where to find answers if this is the wrong place.

  • Moving domain currently on Google Apps to my own machines

    - by mag
    I own a domain which currently uses Google Apps (it was free back then). Due to recent events I have decided I want to move everything right where I can control the data, which basically means I have the idea of either using a dyndns solution and have at home my own mail server or, better, use an hosted machine to retrieve the mail and the move it via mua to a local machine. My problem is that I know basically next to nothing about DNS and stuff, while I have installed mail servers before. :) [I simply never had the need to work with DNS...] I'd really appreciate if someone could point me in the right direction: what do I need to do to: terminate the Google Apps management of the domain setup dns entries to that mail goes to the new server instead of Google Apps Additionally: if I decide to go the "hosted route" and I put up a machine via a supercheap hosting seller (say, the cheapest OVH one is a few euros a month), how can I tell the world that that machine is the mail server? Of course I would be wise to do a full backup of the mail on Google Apps, and that's easy enough to do by imap (right?).

  • nginx php-fpm trouble

    - by Patrick
    Hello, we're using php-fpm and have trouble getting the scripts to work if we change the 'root' value in nginx.conf. location ~ \.php$ { root /usr/share/nginx/html ; If we change that root to point to other directory, even if it's /usr/share/nginx/html/crap, it wouldn't work. The directory exists of course. It's like it can read the file in that directory, but not execute it. I've checked all file permissions. Anyone has any idea?

  • Uninstalling ATI's drivers and installing NVIDIA's?

    - by whydidithavetobreak
    I replaced my card but I'm not sure how to set things up on Ubuntu. When the computer boots, it doesn't start GDM (I think that's what it's called). Instead, it asks me to log in the command line. If I try to do a startx, it tells me there is no AMD device connected or something to that extent. I originally installed the ATI drivers using the GUI. It said that I was using the limited drivers or something to that extent with a popup on the right of one of the taskbars, so I clicked there and updated it. I think it could also be reached by going to system administration restricted drivers or something close to that. I tried installing the nivida drivers by doing a "sudo apt-get install nvidia-glx-185" and then doing "sudo modprobe nvidia" and "sudo nvidia-xconfig" as this guy says but that didn't work. Modprobe couldn't find anything related to Nvidia and nvidia-xconfig wasn't an available command for me. Since I wasn't sure how to remove the ATI drivers I did that without messing with them. Not sure if that was a good idea.

  • My internet connection slows or dies unexpectedly

    - by genesis
    I installed Ubuntu 10.04 once again and I'm having some problems which I had before, but I have no idea how I solved them. On Windows, everything's working fine and I had no problems with this. My problem is that sometimes, when browsing through the internet, webpages just start to load really slow, sometimes it doesn't load anything at all (Error 118 (net::ERR_CONNECTION_TIMED_OUT): The operation timed out.) and it starts to work after few minutes. My IPv4 settings are automatic (DHCP), and IPv6 settings are Ignored/Disabled. I think my previous problems had something to do with IPv6, but I'm not sure.

  • ASUS EeePC 1001PX, hard disk clicking in Ubuntu Maverick

    - by MeanEYE
    I just received my new Asus EeePC 1001px netbook. After installing Ubuntu 10.10 on it, I've noticed that my hard drive is making a clicking noise. Now this is not a loud clicking noise nor it's constant (only sounds occasionally and when hard disk is not writing or reading anything). Another strange thing is, this only happens when netbook is using battery power, the moment I plug in AC power clicking stops. Additionally I noticed that when I go into BIOS I can hear the click only once, same thing happens if I boot Ubuntu from USB. That led me to believe the problem is within operating system. I did all the surface scans and SMART tests and everything seems to be fine. Now noise sounds like heads are trying to "park" themselves so I tried disabling "spin down" option in Power Management but it didn't help. Any idea?

  • How long do uploaded files stay in the tmp folder in Linux Ubuntu?

    - by Jean-Nicolas Boulay Desjardins
    I am building a web application where my users will be able to upload files. After the files are uploaded I need to send the files to two other servers, and after they will be deleted from the server where they were just uploaded to. I am wandering is it a good I idea to keep the uploaded files in the tmp/ folder the time the uploaded files are sent to the other two servers or should I move them to another folder incase they get deleted? I am also wandering because I would like to know if I have to build a cron script to get rid of the files that have been transfered to the other servers so that I get my disk space back.
