  • Netgear router keeps disconnecting iPhone

    - by DisgruntledGoat
    My old router (Voyager 2091) packed up so I just got a new router - a Netgear N150 model DGN1000. My laptop connects OK wirelessly, but my iPhone 4S is constantly getting "disconnected" - it has perfect wifi signal and is seemingly connected to the router, but no pages load (it says "server cannot be found"). If I disconnect manually ("forget this network") then reconnect, it works fine again for a random amount of time (usually 10-30 minutes) then I get the same problem again. I've done some searching and this appears to be a known problem - there are dozens of forum posts out there lamenting similar connection problems. The only advice I have seen is to set a specific channel under Wireless Settings on the router CP, although every forum post recommends a different channel! 1, 3, 5, 6, 11... I have tried them all for hours at a time and get the exact same problem. The firmware is up to date. Is there an actual solution for this, or do I need to get a different router just to be able to use my iPhone?

  • Patch management on multiple systems

    - by Pierre
    I'm in charge of auditing the security configuration of an important farm of Unix servers. So far, I came up with a way to assess the basic configuration but not the installed updates. The very problem here is that I just can't trust the package management tools on those machine. Indeed some of them did not sync with the repository for a long time (So I can't do a "yum check-updates" on Redhat for example). Some of those servers are not even connected to the internet and use an company repository. Another problem is that I have multiple target systems: AIX, Debian, Centos/Redhat, etc... So the version could be different (AIX) and the tools available will be different. And, last but not least, I can't install anything on the target system. So I need to use a script to retrieve the information and either: process it directly or save the information to be able to process it later on a server (Which may happen to run a different distribution than the one on which the information have been retrieved). The best ideas I could come up with were: either retrieve the list of installed packages on the machine (dpkg -l for example on debian) and process it on a dedicated server (Directly parsing the "Packages" file of debian repositories). Still, the problem remains the same for AIX and Redhat... or use Nessus' scripts to assess vulnerability on the installed packages, but I find this a bit dirty. Does anyone know any better/efficient way of doing this ? P.S: I already took time to review some answers to similar problems. Unfortunately Chef, puppet, ... don't meet the requirements I have to meet. Edit: Long story short. I need to have the list of missing updates on a Unix system just like MBSA on Windows. I'm not authorized to install anything on this system as it's not mine. All I have are scripts languages. Thanks.

  • How to do the processing and keep GUI refreshed using databinding?

    - by macias
    History of the problem This is continuation of my previous question How to start a thread to keep GUI refreshed? but since Jon shed new light on the problem, I would have to completely rewrite original question, which would make that topic unreadable. So, new, very specific question. The problem Two pieces: CPU hungry heavy-weight processing as a library (back-end) WPF GUI with databinding which serves as monitor for the processing (front-end) Current situation -- library sends so many notifications about data changes that despite it works within its own thread it completely jams WPF data binding mechanism, and in result not only monitoring the data does not work (it is not refreshed) but entire GUI is frozen while processing the data. The aim -- well-designed, polished way to keep GUI up to date -- I am not saying it should display the data immediately (it can skip some changes even), but it cannot freeze while doing computation. Example This is simplified example, but it shows the problem. XAML part: <StackPanel Orientation="Vertical"> <Button Click="Button_Click">Start</Button> <TextBlock Text="{Binding Path=Counter}"/> </StackPanel> C# part (please NOTE this is one piece code, but there are two sections of it): public partial class MainWindow : Window,INotifyPropertyChanged { // GUI part public MainWindow() { InitializeComponent(); DataContext = this; } private void Button_Click(object sender, RoutedEventArgs e) { var thread = new Thread(doProcessing); thread.IsBackground = true; thread.Start(); } // this is non-GUI part -- do not mess with GUI here public event PropertyChangedEventHandler PropertyChanged; public void OnPropertyChanged(string property_name) { if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs(property_name)); } long counter; public long Counter { get { return counter; } set { if (counter != value) { counter = value; OnPropertyChanged("Counter"); } } } void doProcessing() { var tmp = 10000.0; for (Counter = 0; Counter < 10000000; ++Counter) { if (Counter % 2 == 0) tmp = Math.Sqrt(tmp); else tmp = Math.Pow(tmp, 2.0); } } } Known workarounds (Please do not repost them as answers) Those two first are based on Jon ideas: pass GUI dispatcher to library and use it for sending notifications -- why it is ugly? because it could be no GUI at all give up with data binding COMPLETELY (one widget with databinding is enough for jamming), and instead check from time to time data and update the GUI manually -- well, I didn't learn WPF just to give up with it now ;-) and this is mine, it is ugly, but simplicity of it kills -- before sending notification freeze a thread -- Thread.Sleep(1) -- to let the potential receiver "breathe" -- it works, it is minimalistic, it is ugly though, and it ALWAYS slows down computation even if no GUI is there So... I am all ears for real solutions, not some tricks.

  • Laptop Overheating with Windows 8

    - by Dany Khalife
    I recently installed Windows 8 on my HP G62 Laptop and i have been noticing a very strange problem with it. Let alone, for lets say 5 minutes, without even touching it, it starts to heat up and it reaches about 60 degrees (Celsius) with absolutely no applications open (not just on desktop but overall). I dug in a little deep and found out that Maintenance was running when the computer was Idle, so i turned that off From the System's Task Scheduler, and while there i also turned off other services i did not need hoping that would solve the problem. So after a few days, i noticed that the average temperature of my laptop dropped from 55 to 48 degrees while working on Visual Studio. And when i thought the problem had disappeared, it still did show up, only not after 5 minutes, but more like 10 minutes... Here is what i have done so far: Replacing the thermal paste on the CPU and the fan and cleaning the fan (this was like 6 months ago) Using a laptop cooler Running a virus scan (i just formatted my laptop so it would be really weird if i already caught something but who knows) Right now, i believe it has something to do with my gfx driver (Even though it IS up to date, looking closely at the screen, i can see the pixels slowly refresh (kinda like watching static on TV) which i wasn't able to do on Windows 7. If you have any ideas, let me know. Thanks

  • Require a very simple bash-based webserver for logging XML POST [on hold]

    - by Syffys
    As in title, it's for testing purpose and I need it to be extremely light (1 line to 1 single light file). Here is a XML query sample: XML_QUERY=$(cat <<EOF <?xml version='1.0' encoding='UTF-8'?> <Test></Test> EOF ) curl -H "Content-type: text/xml; charset=utf-8" -H "Soapaction: \"\"" -k -d "${XML_QUERY}" http://localhost:8088 Here are some of the tracks I have found so far even if I wasnt able to adapt them to work as I expect: Netcat minimal webserver: Problem is that my nc does not have the -q option, so the connection is closing before delivering the XML content Netcat Only webserver: Same as above Thanks in advance! EDIT: As it's been asked, I'm running Linux Redhat, even if the distro does not really matter and the OS implied since I'm asking a bash-based solution... Also about my topic being on hold: "Instead, describe your situation and the specific problem you're trying to solve" = I though this was exactly what I was doing, but ok I'll reword: My situation: bash environment (which can also include some standard linux tool: netcat, python or whatever) My specific problem: please see title: Require a very simple bash-based webserver for logging XML in HTTP POST for testing purpose

  • OCCI createEnvironment Blocks My Thread

    - by sahs
    Hello, I'm writing a multi-threaded application, where there is a main thread which distributes tasks to the worker threads. According to the task, a worker thread creates a connection, by using a global occi environment. When a worker thread completes its task, it closes the connection (I'm sure, there is no exception thrown while termination). My problem is that after a while(sometimes 5 mins, sometimes 5 hours) the threads cannot get connection from the environment, and they get blocked there. What can be the problem?

  • libvirt's dnsmasq does not respond to dns queries or provide dhcp

    - by Jeremy
    This is on Ubuntu 10.04 server, using KVM to run Ubuntu guests. This system has been working for a long time and I have not changed anything (other than applying security updates), but today I found dnsmasq no longer responds to requests. I cannot say how long this has been broken for me because I don't frequently use the NAT'd guests. So it could have started just after the last updates or some other event and I just now found it. I can connect to port 53 with telnet at 192.168.122.1. I've flushed ip-tables to be sure it wasn't firewall rules and that is not the problem. dnsmasq is running, virsh reports default network as stared. I can't find ANY information on troubleshooting libvirt dnsmasq except that it won't play well with other instances of dnsmasq, which is not the problem. I cannot even find where log entries might be for this service. Any ideas on where to look for more information? edit to add: I added another network and that one works fine. I guess I have a workaround but would still like to figure out how to troubleshoot this problem.

  • tmpreaper, --protect and a non-root user

    - by nsg
    Hi, I'm a little confused. I have a download directory that I want to remove all files older then 30 days with tmpreaper. Just one problem, the directory in question is a separate partition with a lost+found directory, of course I need to keep it so I added --protect 'lost+found', the problem is that tmpreaper outputs: error: chdir() to directory 'lost+found' (inode 11) failed: Permission denied (PID 30604) Back from recursing down `lost+found'. Entry matching `--protect' pattern skipped. `lost+found' I have tried with other pattern like lost* and so on... I'm running tmpreaper as a non-root user because there is no reason for superuser privileges because I own all files (except lost+found). Are I'm forced to run tmpreaper as root? Or are my shell-skills not as good as I thought? I guess the problem is: tmpreaper will chdir(2) into each of the directories you've specified for cleanup, and check for files matching the <shell_pattern> there. It then builds a list of them, and uses that to protect them from removal. Any thought and/or advice? Edit: The command I'm trying to run is something like $ /usr/sbin/tmpreaper -t --protect 'lost+found' 30d /mydir 1> /dev/null error: chdir() to directory `lost+found' (inode 11) failed: Permission denied Edit 2: I read the source code for tmpreaper-1.6.13 and found this if (safe_chdir (dirname)) exit(1); and if (chdir (dirname)) { message (LOG_ERROR, "chdir() to directory `%s' (inode %lu) failed: %s\n", dirname, (u_long) sb1.st_ino, strerror (errno)); return 1; } So it seems tmpreaper needs to be able to chdir in to all directories, ignored or not. I see two options left Run tmpreaper as root Move the download directory Find a alternative tool (tmpwatch?) I will give it some more research before i make a choice.

  • Outlook locking network connection/session?

    - by HaydnWVN
    Scenario: We have an 'automatic orders' machine sat in the corner running XP with Outlook 2003. Its job is to check for new emails on a specific account, when it encounters one it checks the e-mail body for specific wording to determine which customer it is from (using a macro), then it checks the attachment for specific order codes before parsing the attachment to create a .csv file (which is then e-mailed onto one of the sales team) before importing the .csv into our bespoke ERP/Sales Order system to create an order. Problem: Periodically the machine will have symptoms of a lost network connection (unable to connect to any network source). Sometimes after several days, sometimes over a week. Volume of emails/orders processed does not seem to be linked. Additional info: The machines .pst is stored on a mapped network location. The .csv created is stored on a mapped network location. This is a workgroup, not a domain. All network drives are Samba shares from an Ubuntu fileserver. Our bespoke system runs from a database (MySQL) Ubuntu server. Our troubleshooting so far: I have switched machines (previous was Win2000) with the same symptoms. Restarting the machine FIXES the problem. Closing Outlook and then end tasking an Outlook.exe background process FIXES the problem. If you close Outlook, without end taking the background process, outlook will not reopen (saying it cannot find the pst file & it will not open any network location). Does Outlook have some kind of 'max session' linking it to network activity that is not closing after a mail request? Could Auto-archive be causing this? Is there a tool to check/display what each outlook.exe process is doing? Have not found many ways to troubleshoot this yet, as it is so infrequent...

  • Detecting I/O errors in a NON BLOCKING SOCKET

    - by ripunjay-tripathi-gmail-com
    I am writing a client - server system in which I used NON-BLOCKING sockets. My problem is to detect error { while performing send() or write() } that may occur while data transfer. Example lets say, while the data is being transferred the peer crashes. Another case there is some network problem, something like wire unplugged etc. As of now, I am using a high level ACK, that peer sends after receiving the complete data. Ripunjay Tripathi

  • Weirdly high ping on direct ethernet connection?

    - by Antriel
    I bought new Lenovo IdeaCentre H430 pc and I'm having problem with high pings. Windows 7 with on-board realtek NIC. Fresh install, fully updated, drivers installed from included CD. When I start pinging router (direct 1Gb ethernet connection, 1 hop), pings start at <1ms (which is fine) and after a while they jump to 300-1000ms. I loaded up live ubuntu to test if the problem might be in HW. It's not, in ubuntu pings were always <1ms. I also noticed that when I start using connection somehow, pings go down to 1ms, but go back up when I stop using it (tested by accessing live camera feed on LAN). Power Options set to max performance. I disabled Interrupt Moderation on the NIC, didn't help. I tested it in the safe mode with networking, same problem there. It slows down our client-server based programs and I have no idea what's causing it. All I could google up was that disabling Interrupt Moderation would help, it didn't though. Anyone had similar problems? tl;nr: Computer is giving high pings to router when idle and normal pings when network is under load, it slows down our software significantly.

  • How I can fix the "Display Driver has stopped responding and has recovered"?

    - by Vitor Rangel
    I'm using a GeForce GTX 580, with Windows 7 64-bit. The driver version of the GTX is 301.42. The problem happens after a few minutes, when I'm playing specifc games. It won't happen in all games - And I don't have any idea why these games doesn't work. The games that doesn't work: Battlefield 3, Civilization V, Sniper Elite V2. The games that work: Mass Effect 3, Crysis 2, Team Fortress 2, Left 4 Dead 2, Skyrim, L.A. Noire. As you can see, it's not a problem of "The games that demand more stop working". I've tryed updating the driver of the graphics-card, the bios of the motherboard, even formated my computer (It was needing it) and instaled every driver in the last version possible. This problem happens since I bought my graphics-card, 6 months ago. After a few minutes, from 10 to 20, the pixels in the monitor become strange, with random colors and effects, like it was broken. Then, everything goes black, and the message appears "Display Driver has stopped responding and has recovered". After that, I need to close the game and start again. I am not overclocking, and my temperature never goes higher than 70ºC.

  • Office365 Exchange: Cannot open shared two calendars in Outlook

    - by Mark Williams
    The problem: Outlook won't open the calendars on another user's mailbox and and a room mailbox, even when users have permission. Note: This problem is affecting more than one account on more than one machine. So I have a room mailbox and a personal mailbox on Exchange, both with shared calendars. There is a security group called "Scheduling Users" that have editor rights on both of these calenders. The room mailbox was created using PowerShell, per the instructions posted online (http://help.outlook.com/140/ee441202.aspx). Sharing worked on both of these folders initially. Users can still access these folders using OWA. So on to the problem. When users try to open these calendars in Outlook they receive one of the following messages. The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance. Cannot open this item. Cannot open the free/busy information. The attempt to log on to Microsoft Exchange has failed. What I have tried so far: Resetting the permissions on both of the mailboxes. I deleted the security group permissions on both mailboxes, applied the change, then waited a bit and gave the permissions back. Deleted the OST file of the shared calendar from the Outlook data directory That is all I have been able to find online. Any thoughts? I have been going back and forth with the Office365 support folks for a while and they seem stumped too.

  • Windows 8.1 in a VMWare Workstation 10 guest's mouse is missing, but only sometimes

    - by Rob Perkins
    I have VMWare Workstation 10 running on a Windows 7 machine, hosting a k guest OS. Before upgrading to WS 10 I was using version 9, and the Win8 guest OS ran without difficulty or error conditions. Since upgrading and installing the most current VMWare Tools inside the guest after upgrading to version 10, there are circumstances where the mouse pointer is not visible; the mouse position appears stuck at a screen location which is not the center of the virtualized display; and mouse click and scrolling events still get processed. Once this begins happening I have to reboot the host machine to get it to stop. (VMWare Tools 9.6.1 build-1378637 is what the WS 10 software installed) The problem seems to correlate with whether the mouse is captured during Win 8.1's bootup process, before control is passed to the login screen. If I explicitly click the mouse into the guest OS and move it slowly around while the system is booting, then I see the mouse after clicking to lift the first screen and expose the password prompt, and there is never a problem within the guest. If I don't do this during bootup, there is no mouse pointer, with the symptoms listed above. I have tried removing and reinstalling VMWare tools, and the other steps published for "mouse problems" from VMWare's chaotic troubleshooting database. The problem persists. Is there a setting in the virtual machine's configuration which could prevent this behavior?
