  • Weird video problem with Linux variants

    - by alex
    I decided recently I wanted to give Linux a go so I first download a Ubuntu boot CD. The boot menu came up fine, and then a glowing Ubuntu logo was in the middle of the screen for a while. Then the screen was flickering orange and black. I guess this is where the GUI should of came up. Pushing Ctrl+Alt+F1 brought me to the command prompt OK. I thought this may have something to do with Ubuntu, so I downloaded Linux Mint. The same sort of thing happened. It booted fine, displayed it's logo for a while and then flickered, only green and black this time. Does this sound like a video card problem? How can I resolve this? Many thanks

  • Why is my router not routing?

    - by dwj
    Starting a week and half ago my router stopped working with my cable modem. I went to sleep with it working and woke up with it not. I swapped in another router and am still having issues; I was gone for 10 days so now I'm back to trying to figure it out. While I was gone I left everything (cable modem, router, and computer) powered off. My setup: Comcast Ambit cable modem (from Comcast) Netgear WGR614 v4 router -- replaced with Linksys WRT54GS v1.1 Windows XP SP3 other computers, all currently unplugged The modem is using the firmware (ver 2.105.2001) provided by Comcast; hardware version 1.3 The Linksys router is using FW ver 4.71.4 (latest for this release of HW), factory defaults I am only using the wired connections; no wireless. I have swapped out all of the cat5 cable. If I plug my computer directly into the cable modem, I can ping by name or number. Everything works perfectly. If I plug my computer into the router and the router into the modem, I cannot access anything outside of my local network. This is the exact setup I've used for the past 5 years; there were no changes in the past year. Now here's the interesting part: I can log into the Linksys router and get status information from it; everything appears good. Using the Diagnostics, I can run ping and traceroute to any site on the internet. These work perfectly. From my computer, I can ping the router and the modem. However, I cannot ping anything on the internet by with name or number. If I plug in another computer, I can ping it successfully. I've included two transcripts below that show these two attempts. Addresses, DNS, gateways, etc. look good. I cannot access the internet through either router. I am at a loss here. Suggestions? Help!

  • Bonjour/DNS Service Discovery queries

    - by senloe
    I'm trying to implement dns service discovery in my application (no, I'm not asking for a programmatic answer). What I believe is one of my big pain points is generating the query. I know I need to send out a multicast broadcast on port 5353 and want to look for devices of type _ipp._tcp and _print._tcp, but I don't know what the question section needs to look like. For example, in SSDP I sent out a query that looks like the following: "M-SEARCH * HTTP/1.1\r\n" "HOST: 239.255.255.250:1900\r\n" + "MAN: \"ssdp:discover\"\r\n" "ST: urn:schemas-upnp-org:device:Printer:1\r\n" "MX: 5000\r\n\r\n" From what I know about a DNS query I need to send something like: "_ipp.tcp,all,all" but I know there needs to be more. Any pointers to documentation, etc would be greatly appreciated! update rfc1035 appears to contain promising information re the message structure.

  • Free mp3 merge for Mac OSX

    - by Lilly
    Hi, I need to merge several mp3 tracks into one, I use MAC OS X 10.5. I want to convert all my Harry Potter CDs to my iPod, but not every minute a new track (as it is on the CDs) but chapterwise. Where can I get a free software? Help, please! (I've already tried: Jfuse, but after I had merged a few chapters it said I had to buy it; emicsoft VOB Converter for MAC; File Stitcher; but since they all were shareware, for free they would only let me merge 2 files at once (that would take me days) or half of each file which is useless of course; iTunes advanced settings ("join CD tracks") when importing the CDs, but it would let me only join the complete CD, not chapters...) (Sorry for my English, hope you could understand what I wanted to say)

  • Toshiba laptop cd drive read causes OS to totally freeze

    - by Fujishiro
    Okay I'll try to write an understandable summary. Forgive me if I'll fail with that attempt though. So. There is a Toshiba Satellite notebook. Got Windows 7 x86 Professional (OEM) installed on it, everything is fine (okay.. somewhat). The problem. If you put an audio or any kind of disc into the drive, something starts to eat the PC. Back then when the owner told me about this, he put an audio disc into the lappy. Winamp caused the IO load, 100%. Tried taskkill, taskkill /T, tried powershell, EVERYTHING. You just can NOT kill winamp or anything which becomes the blocker at that time. Even if you kill almost everything, laptop won't do a clear shutdown. Also I tried to use the force switch at 'shutdown' from cmd, but no use. (So: At these times you can use the laptop, but the blocker/explorer/disc becomes gray as a non-responding app. You can try to kill them, but that won't work, nor you can shutdown the machine). (Also tried using PID, but no use. For the highest IO I used the "select columns" from Task Manager and enabled the IO columns.) My first hunch was the problematic disc, autoplay and it tries to read tries to read (still shouldn't kill the PC). Disabled autoplay, removed winamp. Tried other software, etc. Everything was ok. Few days later the owner tried to put a disc into the machine and it started to reproduce the same symptoms but with a totally different disc. Uhm what to know. Virus is not an option, protected by BitDefender (valid license) and Spybot. Thanks if you have ANY idea about this strange problem. ps.: For now, the owner uses Daemon tools + Blindwrite as an alternative for those apps which wouldnt start without the disc.

  • I love google Chrome, but some non-static pages like Piwik render it unresponsive

    - by gogowitsch
    The web-stat software Piwik stops reacting on mouse clicks after 1-2 seconds. The same is true for Google Maps and Producteev (but GMail and most other pages work like a charm). These rely heavily on JS, and work without Flash. I can click for a very short time period and then the mouse cursor doesn't feel the UI anymore (it doesn't turn into a I over input fields, though it moves; if the freeze occured while the pointer was over an input field, the cursor keeps being a I) and all clicks on the DOM are being ignored by Chrome. No message appears, neither obvious nor in the Console (F12). There is no obstructing div or the like in the DOM (F12). Since I couldn't find any hints on the source of my problems, I suspected my plugins and extensions. Unfortunately, neither deactivating all plugins nor all extensions solved the problem. for the problematic pages, it always happens no Dropbox running several GB of free RAM the taskmanager doesn't show any high CPU or memory utilization (the offending tab uses 30 MB and uses 0-1 % CPU) all problematic pages work in other browsers (Chrome, Firefox, IE) the rest of the computer is very responsive the computers use different security suites (Kaspersky and Avira) The effect exists between several (synchronized) Chrome instances on different machines, all running Windows 7. Both the OS and Chrome are updated automatically. Other tabs and the Chrome chrome (tabs, menus, toolbar buttons of the browser itself) still work. I really don't like switching between browsers. Any ideas?

  • Computer crashes and won't start, LED indicator blinks slowly

    - by hexacyanide
    I have a MSI K8NGM2-FID motherboard coupled with a AMD Athlon 3700+ and an Antec TPII-550 power supply. The computer crashes at random times in operation, sometimes taking a while to crash, and sometimes crashing right after Windows XP shows the desktop after boot. The CPU temperature is always in the safe range, usually 30-33 degrees Celsius, and swapping the RAM has not done anything, so the crashes aren't cause by the RAM. What could be causing this? If the motherboard were fried, would the computer even boot at all? What causes inconsistent crashing of the computer? After the computer crashes, the LED power indicator blinks about once a second, and the computer does not respond to the power button. This behavior continues until the computer's power supply is completely removed.

  • What's the likely culprit in email delay?

    - by Kiki
    If anyone can shed light or point me to a tutorial, I'd appreciate it. We are a tiny company and have experienced occasional delays in receiving email sent between staff members. We are in separate cities but all in the same state; our webhost/email ISP is across the country from us. If it matters, we're on Macs and most of use Entourage. Our email configurations are POP server: companyname.com and SMTP: smtp.companyname.com (When we used our DSL providers for SMTP we had unreliable service) Our ISP says they're not seeing delays related to their equipment and the problem is elsewhere in the network. A co-worker believes that the delays are with the ISP. Is there a good way to figure this out?

  • OSX's built-in VNC server disconnects me randomly, but frequently

    - by ZorbaTHut
    I've been using OSX's VNC service to connect remotely from a Windows XP box, via TightVNC. Everything seems to work normally, except that frequently - anywhere from ten seconds to ten minutes - the connection locks up entirely, without any sort of error message. The only solution is to reconnect and wait for it to lock up again. How can this be fixed permanently?

  • Tips on setting up a virtual lab for self-learning networking topics

    - by Harry
    I'm trying to self-learn the following topics on Linux (preferably Fedora): Network programming (using sockets API), especially across proxies and firewalls Proxies (of various kinds like transparent, http, socks...), Firewalls (iptables) and 'basic' Linux security SNAT, DNAT Network admininstration power tools: nc, socat (with all its options), ssh, openssl, etc etc. Now, I know that, ideally, it would be best if I had 'enough' number of physical nodes and physical network equipment (routers, switches, etc) for this self-learning exercise. But, obviously, don't have the budget or the physical space, nor want to be wasteful -- especially, when things could perhaps be simulated/emulated in a Linux environment. I have got one personal workstation, which is a single-homed Fedora desktop with 4GB memory, 200+ GB disk, and a 4-core CPU. I may be able to get 3 to 4 additional low-end Fedora workstations. But all of these -- including mine -- will always remain strictly behind our corporate firewall :-( Now, I know I could use VirtualBox-based virtual nodes, but don't know if there are any better alternatives disk- and memory- footprint-wise. Would you be able to give me some tips or suggestions on how to get started setting up this little budget- and space-constrained 'virtual lab' of mine? For example, how would I create virtual routers? Has someone attempted this sort of thing before: namely, creating a virtual network lab behind a corporate firewall for learning/development/testing purposes? I hope my question is not vague or too open-ended. Basically, right now, I don't know how to best leverage the Linux environment and the various 'goodies' it comes with, and buying physical devices only when it is absolutely necessary.

  • Why do Finder and du report different file size?

    - by flipdoubt
    I am writing a geektool 3 script to show the size of a particular VMware Fusion virtual machine. Get Info in Finder says the file is "52.91 GB". I run the following du command to get the file size: > du -hs ~/Documents/Virtual\ Machines.localized/MY-PRECIOUS-7.vmwarevm | awk '{print $1}' This du -hs command returns the file size as "49G". What accounts for the difference from what Finder reports? Alternatively, I have tried replacing the -s option with the -d option like so: du -hd ~/Documents/Virtual\ Machines.localized/MY-PRECIOUS-7.vmwarevm | awk '{print $1}' This du -hd command returns the file size as "59G". What accounts for the difference between Finder, du -hd, and du -hs? Also, this du -hd command produces no output in geektool 3. What gives?

  • Microsoft equation editor space problem

    - by Keshav Prasad
    Hello all, When I use the Microsoft equation editor, if I have a word that is greater than 10 characters in length, the equation editor automatically breaks the word and puts spaces in between them when the object is embedded in a powerpoint slide. For example- If I have the word "automatically" in the equation editor, it shows up just fine when I am editing the text in the equation editor. But when I update this object to the powerpoint slide, it shows up as "automatica lly". There is a tab or 5 spaces between "automcatica" and "lly". Is there any way to solve this problem? Thanks! -Keshav

  • Crypto-Analysis of keylogger logs and config file. Possible?

    - by lost.
    Is there anyway Encryption on an unidentified file can be broken(file in question: config file and log files from ardamax keylogger). These files date back all the way to 2008. I searched everywhere, nothing on slashdot, nothing on google. Ardamax Keyviewer? Should I just write to Ardamax? I am at a loss of what to do. I feel comprimised. Anyone managed to decrpyt files with Crypto-analysis? More Information-- There are log files in the folder and a configuration file, "akv.cfg". Is it possible to decrypt the files and maybe getting the attackers email address used to receive the keylogger logs? I've Checked ardamax.com. They have an built-in log viewer. But its unavailable for download. If superuser isn't the proper place to ask, know where I might get help?

  • Remotely push DNS server to client via OpenVPN

    - by wishi
    Hi! When I try to push a DNS server via the OpenVPN server-config I don't get that server to be the first DNS server on the connected client system. It ends up being specified as an alternative DNS server. push "dhcp-option DNS 89.238.75.146" # DNS-Server 1 (local djbdns) To overcome certain network restrictions, if they're at place, I use 443 TCP. - That means that my DNS queries are sent via TCP (if I manually reconfigure the DNS server), which doesn't scale very well from a performance perspective. Are there any kewl solutions for that? Marius

  • Looking for Driver Diagnostic and Repair Software

    - by risingTide
    Greetings, I am currently plagued with BSODS on startup (both normal and safe mode) for my XP Pro. After much troubleshooting I have determined it is a driver problem. However, because I cannot even boot I do not know how to fix it. I am looking for some specific driver diagnostic and repair software that I can use from another computer to access and fix the driver problem on the problematic XP drive. (I can access the problematic drive via USB from another computer.) I will offer more details about my specific situation if it is helpful or necessary. Thank you for your time!

  • does bootcamp provide the best drivers for windows 7, or should i install the ones windows 7 suggest

    - by hatorade
    I'm running windows 7 via bootcamp on my MBP (the model that was newest in summer 2009). Bootcamp is up to date. Windows 7 just suggested I install a new driver for my nvidia card. However, I was under the impression bootcamp provided the most optimal drivers for windows 7 to run on my MBP's hardware. Should I stick with what bootcamp gives for my video driver, or update to the one windows 7 suggests?

  • On the fly volume compression (waveform capping) for VLC or OS X

    - by Grammar Nazi
    I'm looking to impose a hard limit on a movie. In particular when I have earbuds in and a reasonable volume set, loud or sudden sounds (gun shot, dramatic sound effects, gun fire, etc) are loud enough to hurt. Lowering the volume makes speech and other sounds hard to hear. Is there a third party on-the-fly solution for this, or a plug-in for VLC that I can use?

  • Windows 7 - Add shell command for .png file

    - by Aximili
    On Windows XP, you could go to Folder Options - File Types, select PNG, create a new action, such as this Action: Crush Application: "F:\Programs\PNGCrush\crush.bat" "%1" So you can right click on a .png file and select Crush. How do you do this on Windows 7? I assume through regedit or .reg file, but how? EDIT: Thank you for all your replies... but I'd like to avoid "Open With" or 3rd party program if possible.

  • powerpoint make computer shut down on dell optiplex 760

    - by yael
    At my office we upgraded group of computers to windows 7 + office 2010, few of us have problem that when we work on powerpoint - once in a while the computer suddenly shut down (with out any message). Some of us - has no such problems. We checked and fount that the people who experience problems - use Dell Optiplex 760 PC, and everyone that have no problems use other models. We also found out that the processors of the 760's are not the same - some are Intel E7400 and one is Intel E8400, so I suspect that maybe the mother board is the problem Does any one no this problem? Does any one have an idea about it? Any help will be appreciated. Thanks, Yael

  • Getting around url block for game

    - by Josh T
    So I play a game called Battlefield Play4Free (www.battlefield.play4free.com). Its essentially a giant browser plugin. The admin on my computer used to have the url battlefield.play4free.com/en/playnow.html blocked which only blocked the page that launches the game (i found a way to launch the game without going to that page and the game worked fine). Now it blocks battlefield.play4free.com which thus blocks all subpages. However, I have found that if I change it to an https and go to https://battlefield.play4free.com/en/login.html to login and then https://battlefield.play4free.com/en/playnow.html I can launch the game. However, when the game launches the borders and everything show but the window content is just a giant blockpage (the same one that shows up when I go to battlefield.play4free.com in the browser) and the blocked page is battlefield.play4free.com (main page). Is there any way I can get around this? I need a way to make the game access the server without going through the browser i.e. make the game use a proxy to get the data or somehow get past the besafe block. I was thinking perhaps you could get around it if you could get the game to make a direct request to the server and not through the url/browser, I know this works because I have a torrenting app that even tho torrent sites are blocked in the browser, the app makes a direct request and thus is not blocked. By the way, the program that blocks everything is besafe or besecure something like that. I do have access to an admin account (on the computer not the besafe program) as well as router access and pretty much anything else. Thanks so much!
