  • Weird Network Behavior of Home Router

    - by Stilgar
    First of all I would like to apologize because what you are going to read will be long and confusing but I am fighting this issue for 3 days now and am out of ideas. At home I have the following setup 50Mbps Internet connects into a home router A 2 desktop computers connect to router A via standard FTP LAN cables including one where the cable is ~20m long. a second router B connects to router A via standard FTP LAN cable X (~20m long). several devices connect to the wireless network of router B and there are a couple of desktop computers connected to it through FTP LAN cables. For some reason computers connected to router B when it is connected via cable X have very slow Internet connection. It is like 5 times slower than what is expected. This is the actual problem I am trying to solve. Interesting facts If a computer is connected to cable X directly instead of through router B the Internet speed is just fine (up to the 50Mbps I get from the ISP). Tested with two computers. I have tried replacing router B with another router C and the problem persists. If I connect router B via another cable to the same ports with the same settings everything seems to work fine and computers connected to router B have quite fast Internet I have tested mainly via Speedtest.net but I have also achieved similar speeds when downloading a file The upload speed is quite higher than the download speed in all cases. Note that my ISP usually has higher upload speed (unless it manages to hit the 50Mbps cap) It seems like the speed when connecting through router B with cable X is reduced 4-5 times no matter what the original speed is. For example via router B I get 10Mbps speed to local servers where I get 50Mbps when connected on router A. If I use a distant server where the ISP is only able to provide 25Mbps I get 4-5Mbps on router B. WiFi is slower than LAN on both routers (which is normal) but the reduced speed is reduced proportionally for WiFi. In addition the upload speed is normally higher from the ISP and it is also reduced proportionally. I have tried two different network configurations. One where I have NAT behind NAT where router B connects to router A via the WAN port and has its own DHCP. Second where router B connects to router A via standard LAN port and has DHCP disabled. In this configuration router B serves as a switch and the Network Gateway for computers connected to router B is the internal IP address of router A. Both configurations work just fine but both manifest the reduced speed issue. pings seem to work just fine As far as I can tell none of the cables is crossed The RJ45 setup for cable X orange orange-white brown brow-white blue blue-white green green-white This is a big problem for me since cable X passes through walls and floors and is very hard to replace. I also may have gotten some of the facts wrong because I am almost going crazy with this issue and testing includes going several floors up and down the staircase. One hypothesis I came up with is that the cable is defective in such a way that the voltage from the router affects its performance. When it is connected to a computer it performs just fine but the router has less power. Related hypothesis includes the cable being affected by electricity cables in the walls when the voltage is low. (I know nothing about electricity) So any ideas what to do, what to test or what the issue may be?

  • Printing to a Windows 7 incompatible printer shared on supported Windows XP machine

    - by MGSoto
    I have an HP Laserjet 1500 that is supported by Windows XP, but not supported by Windows-7. I want to print from my 7 machine(s) to my XP machine on this printer. Is there some sort of way to send a generic job (like sending raw postscript or something) to the XP machine, which will then print it with the proper drivers? Is there a virtual printer that has drivers for both XP and 7 that will just re-print it on the XP machine using the real printer?

  • Syntax for find on Mac OS X

    - by hekevintran
    I have a project directory that contains source code and subdirectories of source code. I want to use the Unix program find to search recursively for the names of files of certain extensions. The versions of find on Linux and Mac OS X behave differently. # Works in Linux find . -type f -regex ".*\.\(py\|html\)$" # Neither of these works in Mac OS X find . -type f -regex ".*\.\(py\|html\)$" find . -type f -regex ".*\.(py|html)$" How do I write this command so that it will run on Mac OS X (and hopefully on Linux too)?

  • UITableView crashes when trying to scroll

    - by Ondrej
    Hi, I have a problem with data in UITableView. I have UIViewController, that contains UITableView outlet and few more things I am using and ... It works :) ... it works lovely, but ... I've created an RSS reader class that is using delegates to deploy the data to the table ... and once again, If I'll just create dummy data in the main controller everything works! problem is with this line: rss.delegate = self; Preview looks a little bit broken than here are those RSS reader files on Google code: (Link to the header file on GoogleCode) (Link to the implementation file on Google code) viewDidLoad function of my controller: IGDataRss20 *rss = [[[IGDataRss20 alloc] init] autorelease]; rss.delegate = self; [rss initWithContentsOfUrl:@"http://rss.cnn.com/rss/cnn_topstories.rss"]; and my delegate methods: - (void)parsingEnded:(NSArray *)result { super.data = [[NSMutableArray alloc] initWithArray:result]; NSLog(@"My Items: %d", [super.data count]); [super.table reloadData]; NSLog(@"Parsing ended"); } (void)parsingError:(NSString *)message { NSLog(@"MyMessage: %@", message); } (void)parsingStarted:(NSXMLParser *)parser { NSLog(@"Parsing started"); } Just to clarify, NSLog(@"Parsing ended"); is being executed and I have 10 items in the array. Ok, here's my RSS reader header file: @class IGDataRss20; @protocol IGDataRss20Delegate @optional (void)parsingStarted:(NSXMLParser *)parser; (void)parsingError:(NSString *)message; (void)parsingEnded:(NSArray *)result; @end @interface IGDataRss20 : NSObject { NSXMLParser *rssParser; NSMutableArray *data; NSMutableDictionary *currentItem; NSString *currentElement; id <IGDataRss20Delegate> delegate; } @property (nonatomic, retain) NSMutableArray *data; @property (nonatomic, assign) id delegate; (void)initWithContentsOfUrl:(NSString *)rssUrl; (void)initWithContentsOfData:(NSData *)inputData; @end And this RSS reader implementation file: #import "IGDataRss20.h" @implementation IGDataRss20 @synthesize data, delegate; (void)initWithContentsOfUrl:(NSString *)rssUrl { self.data = [[NSMutableArray alloc] init]; NSURL *xmlURL = [NSURL URLWithString:rssUrl]; rssParser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL]; [rssParser setDelegate:self]; [rssParser setShouldProcessNamespaces:NO]; [rssParser setShouldReportNamespacePrefixes:NO]; [rssParser setShouldResolveExternalEntities:NO]; [rssParser parse]; } (void)initWithContentsOfData:(NSData *)inputData { self.data = [[NSMutableArray alloc] init]; rssParser = [[NSXMLParser alloc] initWithData:inputData]; [rssParser setDelegate:self]; [rssParser setShouldProcessNamespaces:NO]; [rssParser setShouldReportNamespacePrefixes:NO]; [rssParser setShouldResolveExternalEntities:NO]; [rssParser parse]; } (void)parserDidStartDocument:(NSXMLParser *)parser { [[self delegate] parsingStarted:parser]; } (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError { NSString * errorString = [NSString stringWithFormat:@"Unable to parse RSS feed (Error code %i )", [parseError code]]; NSLog(@"Error parsing XML: %@", errorString); if ([parseError code] == 31) NSLog(@"Error code 31 is usually caused by encoding problem."); [[self delegate] parsingError:errorString]; } (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict { currentElement = [elementName copy]; if ([elementName isEqualToString:@"item"]) currentItem = [[NSMutableDictionary alloc] init]; } (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:@"item"]) { [data addObject:(NSDictionary *)[currentItem copy]]; } } (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if (![currentItem objectForKey:currentElement]) [currentItem setObject:[[[NSMutableString alloc] init] autorelease] forKey:currentElement]; [[currentItem objectForKey:currentElement] appendString:string]; } (void)parserDidEndDocument:(NSXMLParser *)parser { //NSLog(@"RSS array has %d items: %@", [data count], data); [[self delegate] parsingEnded:(NSArray *)self.data]; } (void)dealloc { [data, delegate release]; [super dealloc]; } @end Hope someone will be able to help me as I am becoming to be quite desperate, and I thought I am not already such a greenhorn :) Thanks, Ondrej

  • Why won't Outlook sync with Google Calendar?

    - by mipadi
    A colleague of mine is having problems with Outlook and Google Calendar Sync. He got a new machine and set up Outlook 2007 on that machine. He also installed Google Calendar Sync. However, when he synced Outlook with Google Calendar, he got a number of duplicate entries in Outlook's calendar. We tried deleting all entries in the Outlook calendar and doing a 1-way sync from Google Calendar to Outlook, but the duplicated entries appeared again. We ultimately removed the duplicated entries manually, but we experienced problems pushing the changes back to Google Calendar, so we deleted the calendar in Google Calendar and tried to sync again (using a 1-way sync from Outlook to Google). Now Google Calendar Sync says that it is synchronizing, but no entries appear in the Google Calendar calendar. What could the problem be?

  • Custom signature for Gmail mobile

    - by pilcrow
    Is it possible to use a custom signature for Gmail to be used only when accessed over an iPhone or other mobile device? While I don't find the Sent from my [iPhone|mobile device] siglines to be very pretty, they are a convenient way to explain and excuse the brevity and occasional typo in mobile email.

  • Windows-based video creation with Ken Burns effect

    - by Chris Farmer
    I want to create a video of old photos and I would like to use the Ken Burns effect for more pleasant transitions. I don't think I require inserting any existing video clips into this -- I just want to create a video from my images. It would be nice to be able to add titles and captions, too. Which Windows-based software can help me with this?

  • Synergy 1.4.2 Linux server, OSX client, Media/Function key mapping issues

    - by at165dB
    I'm using an Apple bluetooth keybord to control my Linux synergy server. SSH tunneling, Mouse, Keyboard, and Copy&Paste all work. Linux sees all the media/app keys that are on top of the F# keys correctly. However if I press any of those keys while controlling my OSX client, nothing happens on the client. Running synergys with -d DEBUG1 I can see the following keycode info: Pressing the "dim monitor" key that also serves as F1 generates: new mask: 0x2000 event: KeyPress code=232, state=0x0010 new mask: 0x2000 If I press "fn" and the same key, I can see it sending what I'm assuming is an F1: event: KeyPress code=67, state=0x0010 onKeyDown id=61374 mask=0x2000 button=0x0043 send key down to "foo.cisco.com" id=61374, mask=0x2000, button=0x0043 new mask: 0x2000 event: KeyRelease code=67, state=0x0010 onKeyUp id=61374 mask=0x2000 button=0x0043 send key up to "foo.cisco.com" id=61374, mask=0x2000, button=0x0043 I'm guessing I need to tweak my synergy.conf so that the server sends keys that it currently isn't.

  • Splitting an internet connection between multiple separate subnetworks

    - by pythonian4000
    Problem I have an internet connection that I want to split between four separate networks. My requirements are: I need to be able to monitor the amount of bandwidth and data being used by each network, and notify or control as necessary. The four networks should only be able to connect to the internet, not each other. My parents need to be able to operate it, so it needs a simple, preferably Windows-based GUI. Progress so far Server I have a mini-ITX server with six Gigabit ethernet ports - one for the ethernet internet connection, one for each of the four networks, and one for remote access to the server for administration. Bandwidth control I spent a long time researching solutions here. The majority of the control systems/software I found could control bandwidth usage via QOS, but could not monitor or control the amount of data being used. Eventually I found the SoftPerfect Bandwidth Manager, which has everything I need in terms of monitoring and control - per-interface quota management, usage statistics, a web interface for checking usage, and email notifications when quotas are exceeded. It is also Windows-based and has a simple GUI. Internet sharing This is where I am having issues. I am currently using Windows XP Pro SP2 for the server (yes, I know this is far from ideal, but it's the only spare Windows OS I currently have). I can't use the built-in Internet Connection Sharing for several reasons: The upstream internet router has an IP of 192.168.0.1 which ICS clashes with, and I cannot change the router settings. ICS can only share an internet connection with a single interface, but I have four. I have tried bridging the four network cards, but then the Bandwidth Manager cannot see the four individual interfaces - it only sees the bridge. I have tried setting up Dual DHCP DNS server (and am having issues getting DHCP offers to be received by clients), but that would still require gateway software of some sort, which I have been unable to find. My current attempt is to use OpenVPN, with a server for the internet NIC and a separate client for each of the four networks. My thought is that I could bridge the OpenVPN TAP devices to each NIC, meaning that the Bandwidth Manager would control traffic from the bridge instead of the interface. I have not made much progress here though - I've never used OpenVPN before. Questions Is there a Windows software package that does everything I need? (Unlikely, I know) Is there a Windows software package that will share internet between multiple NICs without bridging? Are either of my about attempts feasible? Would it help to have a newer/server version of Windows? Is there a non-Windows alternative that is easy to use?

  • How to brute force keepass with certain letters and characters

    - by bobbyq
    I forgot my password to keepass but I know pretty much what letters and the order they go in, but I'm not sure if I put anything before or after my "main" password or capitalized anything. I tried every combo I could think of but I still can't get in (invalid/wrong key error). I also enabled use master password and key file(on my flash drive). My question is is there a way to brute force keepass with only certain letters and characters in order? An example of the password would be userab12c3d45 sometimes with quotes or underscores at the beginning and end. Or Is there a word list generator that will do this?

  • Thunderbird: mails not displayed while everything worked a few minutes ago

    - by roland
    Hi all, I upgraded my Kaspersky and I closed everything before launching the upgrade process. Everything went well, but when I launched my Thunderbird, no mail and content were displayed. Everything is blank. Strangely my accounts are detected when expanding Tools/Account Settings. I completely closed Kaspersky and launched Thunderbird again, but it fixed nothing :( It is as if closing Thunderbird has damaged a core file. Any idea how to fix it? Thanks. Roland

  • NAS + XBMC combination

    - by Hendrik
    I currently own a WD Sharespace and I am not too happy about it. It will freeze constantly and its rather slow. I've been thinking of replacing it. I also own a WD HD Live, and it works like it is supposed to, but recently I've seen XBMC in action and I was quite impressed. I've been wondering lately about the possibility of replacing both products with one new device: a fast reliable nas which I can install XBMC on and is capable of rendering video and has an HDMI out. Do any such devices exist for sale or is the only way to build one from scratch? I've seen HTPC's for sale but I've never seen any of them with a raid setup. I've also read about building your own NAS with freeNAS but those setups dont allow you to run XBMC. Does anyone have experience with this?

  • Changing location of the Links folder

    - by Dany Khalife
    I am setting up a small network and i am stuck at rerouting the Links folder on Windows 7. What i am trying to accomplish is to keep some particular directories stored on a server and all client computers will actually link to those folders, one of which is the Links folder. I took a look at the registry and found most of the things in : HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders But the Links folder isn't there so im wondering if it's possible to sync that folder over several PCs too without moving all the user directories to the server Any hint is appreciated!

    I am trying to install postgres on EC2 / EBS. I am following this article and stuck at the following step. sudo su - su postgres - /usr/pgsql-9.0/bin/initdb -D /pgdata I cant find the initdb command located at the stated location, matter of fact i cant find the pgsql* directory at all under /usr folder. Was this changed for Postgres 9.2 or is there an alternate command that would help me initdb? edit 1: I know the folder pgsql-9.0 is version specific, so i was expecting to see more like pgsql-9.2 or similar.

  • Enter key on Mac OS X renames files instead of launching

    - by Matt
    On my Mac when I hit the "enter" key on a file on my desktop or in the finder, it enters the "rename file" mode. 1) How do you actually "launch" or "open" (i.e. double click) the file with only the keyboard? In Windows, the Enter key does this. 2) Is there a way to map the Enter key to do this in Mac instead of rename? Honestly, it makes little sense to me. I mean, how often do you rename something? Once, maybe. How often do you open something? Lots and lots of times.

  • Is dual-booting an OS more or less secure than running a virtual machine?

    - by Mark
    I run two operating systems on two separate disk partitions on the same physical machine (a modern MacBook Pro). In order to isolate them from each other, I've taken the following steps: Configured /etc/fstab with ro,noauto (read-only, no auto-mount) Fully encrypted each partition with a separate encryption key (committed to memory) Let's assume that a virus infects my first partition unbeknownst to me. I log out of the first partition (which encrypts the volume), and then turn off the machine to clear the RAM. I then un-encrypt and boot into the second partition. Can I be reasonably confident that the virus has not / cannot infect both partitions, or am I playing with fire here? I realize that MBPs don't ship with a TPM, so a boot-loader infection going unnoticed is still a theoretical possibility. However, this risk seems about equal to the risk of the VMWare/VirtualBox Hypervisor being exploited when running a guest OS, especially since the MBP line uses UEFI instead of BIOS. This leads to my question: is the dual-partitioning approach outlined above more or less secure than using a Virtual Machine for isolation of services? Would that change if my computer had a TPM installed? Background: Note that I am of course taking all the usual additional precautions, such as checking for OS software updates daily, not logging in as an Admin user unless absolutely necessary, running real-time antivirus programs on both partitions, running a host-based firewall, monitoring outgoing network connections, etc. My question is really a public check to see if I'm overlooking anything here and try to figure out if my dual-boot scheme actually is more secure than the Virtual Machine route. Most importantly, I'm just looking to learn more about security issues. EDIT #1: As pointed out in the comments, the scenario is a bit on the paranoid side for my particular use-case. But think about people who may be in corporate or government settings and are considering using a Virtual Machine to run services or applications that are considered "high risk". Are they better off using a VM or a dual-boot scenario as I outlined? An answer that effectively weighs any pros/cons to that trade-off is what I'm really looking for in an answer to this post. EDIT #2: This question was partially fueled by debate about whether a Virtual Machine actually protects a host OS at all. Personally, I think it does, but consider this quote from Theo de Raadt on the OpenBSD mailing list: x86 virtualization is about basically placing another nearly full kernel, full of new bugs, on top of a nasty x86 architecture which barely has correct page protection. Then running your operating system on the other side of this brand new pile of shit. You are absolutely deluded, if not stupid, if you think that a worldwide collection of software engineers who can't write operating systems or applications without security holes, can then turn around and suddenly write virtualization layers without security holes. -http://kerneltrap.org/OpenBSD/Virtualization_Security By quoting Theo's argument, I'm not endorsing it. I'm simply pointing out that there are multiple perspectives here, so I'm trying to find out more about the issue.

  • Digital Blue Digital Movie Creator 3.0 driver

    - by hjdx
    I'm having a complete 'mare of a time trying to use my schools Digital Blue cameras. We've got the model 3 ones, but can't find the driver disc and using the Windows Hardware Installation Wizard gets me no where! Can you help me to find the driver? When I've used it at my old school it had a piece of software called the Digital Movie Creator, which I've heard you can use to make stop-motion films, which is what I want to do! This is what it looks like http://www.amazon.co.uk/Digital-Movie-Creator-1GB-Card/dp/B000LP30LA/ref=sr_1_2?ie=UTF8&s=software&qid=1265928833&sr=1-2

  • What is the best memory supported by Asus Rampage Formula (1) motherboard

    - by James
    I'm rebuilding a PC from old components I have and I want to know what are the best ram sticks for the Asus Rampage Formula (The first motherboard in the Rampage Formula range) According to the Asus website (HERE) the maximum supported memory is 8GB but when I search through the memory compatibility list there's nothing above 2046mb and the motherboard only supports single or dual-channel memory. Can anyone point me in the direction of a more comprehensive list of compatible memory? Or does anyone know where I can ask about memory compatibility? Note: As far as I know, this model motherboard is no longer in production.

  • Which Firefox add-on is responsible for a rendering bug?

    - by Gilles
    I've found a page that isn't rendered correctly by Firefox with my usual profile. It is rendered correctly with a blank profile. I have quite a few add-ons. One of them is surely the culprit. How can I find out which? Userscripts often affect the rendering. But I turned off Greasemonkey, and it didn't help. So it's something else, presumably an extension (what else could it be? I have no chrome/userChrome.css.). I'm looking for an easy way to find out which one, easier than disabling a bunch of extensions and restarting umpteen times. Related: Create a tool to help users identify a problematic add-on by bisecting the list of installed add-ons — a similar problem which would admit a similar solution. I want to automate this as much as possible; something like git bisect, that doesn't require me to change my actual profile, would be ideal. A Linux-specific solution is fine with me.

  • laptop headphone jack problems

    - by Xitcod13
    A while back my headphones mysteriously started making static noise and one of them stopped working completely. At first I thought it was headphones so I bought new ones. Alas that did not solve the problem. The problem must be inside my headphone jack. I did some research online and they suggested unplugging USB devices. Which has a strange effect of changing the static noises to high frequency Morse code noises (it's the aliens). I don't have this problem when i listen to music on speakers. The static is there on headphones whether there is music or not. I own a soldering iron for electronics and I am quite skilled at soldering. I would appreciate any help I can get. My laptop is the HDX 18. It has 2 headphone jacks that act exactly the same. Interesting thing i just noticed is that when i pull out my headphones almost all the way both of them start working but so do the speakers making the headphones kinda useless. Maybe there is a way to turn of the speakers as a temporary solution. I am using vista x64.
