  • How can I redirect/forward all the UDP/TCP traffic on one interface to another interface in OpenWrt

    - by Sina Sou
    I am new to networking and I have a measurement device (D) that periodically sends all its readings over few UDP multicast sockets (with different multicast IP addresses and different port numbers). That device even listens to a TCP socket simultaneously to modify its configuration on port 7234. Since the device has just a Ethernet interface for communication and I want to make it work wireless, I decided to use a very small wireless open-wrt based router that attaches to the device (D) and redirect/forward all the network traffic(Both UDP/TCP) to the router wireless interface. In order to simplify the problem assume that the Device (D) establishes following sockets (at the same time) UM_SOCK1: UDP mcast socket on 239.1.2.3 port# 50620 UM_SOCK2: UDP mcast socket on 239.1.2.4 port# 50640 TC_SOCK3: TCP DHCP/STATIC ip address 192.168.1.200 port 7234 And (D) is connected to Open-Wrt router (R) via interface en01 (Ethernet) the router has it own wireless interface on (wlan0) I want all the traffic from interface pass through wlan01 and vice versa (bi-directional) en01 <---- wlan01 What would be the minimum iptables or ... commands that I need to make this possible? Even I am wondering if traffic directing can be made easier like if the direction is not going to be based on IP addresses(not desired if the device is connected via DHCP) I would rather redirection to be Interface(en0) based or on MAC address (The best solution since my device has unique MAC address)? Thanks

  • Multi- authentication scenario for a public internet service using Kerberos

    - by StrangeLoop
    I have a public web server which has users coming from internet (via HTTPS) and from a corporate intranet. I wish to use Kerberos authentication for the intranet users so that they would be automatically logged in the web application without the need to provide any login/password (assuming they are already logged to the Windows domain). For the users coming from internet I want to provide traditional basic/form- based authentication. User/password data for these users would be stored internally in a database used by the application. Web application will be configured to use Kerberos authentication for users coming from specific intranet ip networks and basic/form- based authentication will be used for the rest of the users. From a security perspective, are there some risks involved in this kind of setup or is this a generally accepted solution? My understanding is that server doesn't need access to KDC (see Kerberos authentication, service host and access to KDC) and it can be completely isolated from AD and corporate intranet. The server has a keytab file stored locally that is used to decrypt tickets sent by the users coming from intranet. The tickets only contain username and domain of the incoming user. Server never sees the passwords of authenticated users. If the server would be hacked and the keytab file compromised, it would mean that attacker could forge tickets for any domain user and get access to the web application as any user. But typically this is the case anyway if hacker gains access to the keytab file on the local filesystem. The encryption key contained in the keytab file is based on the service account password in AD and is in hashed form, I guess it is very difficult to brute force this password if strong Kerberos encryption like AES-256-SHA1 is used. As the server has no network access to intranet, even the compromised service account couldn't be directly used for anything.

  • How can I add a second hard drive to a previously configured UEFI/ACHI Windows 8 machine?

    - by pflyer
    Recently purchased a new Windows 8 PC. It came with one hard drive. I want to a second hard drive to it. This second hard drive is my data hard drive from my previous computer. However, I have run into issues when the system accesses it. The drive is found in the BIOS. But is not seen by Explorer or Disk Management. I have added the drive to the next available SATA slot: SATA 2. The machine is a UEFI/ACHI based machine. In my reading I have found people documenting the following: 1) adding multiple partitioned hard drives (like mine is) to UEFI based machines is not possible 2) I have seen it suggested that you can only add blank hard drives to UEFI based machines. However, in doing so, I did not have success. I tried to add it as a hard drive with unallocated space and then as a hard drive with a single simple partition. Both attempts failed. My ultimate question: What is the proper procedure for adding a second hard drive to a UEFI/ACHI machine? I do not want to reinstall the OS and start from scratch as I have seen suggested elsewhere. There has to be a way to accomplish this without all that hassle. Thanks in advance for your help.

  • Ubuntu 12.04 partioning an external drive without lossing data

    - by Menelaos Perdikeas
    I have an Ubuntu 12.04 with an external 1.5T disk (just for data). It is /dev/sdc1 seen below: $ df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/sda1 ext4 1451144932 27722584 1350794536 3% / udev devtmpfs 6199460 4 6199456 1% /dev tmpfs tmpfs 2482692 988 2481704 1% /run none tmpfs 5120 0 5120 0% /run/lock none tmpfs 6206724 284 6206440 1% /run/shm /dev/sdc1 fuseblk 1465135100 172507664 1292627436 12% /media/Elements The thing is I would like to implement this rsync-based backup strategy and I want to use my /dev/sdc1 external drive for that. Since the guide mentioned above recommends placing the backup directory in a separate partition I want to repartition the /dev/sdc1 external hard disk but retain existing data in a separate partition. E.g. split /dev/sdc1 into two partitions: (i) one to be used exclusively for the rsync-based backup and (ii) the other for the existing miscellaneous data. How should I go about partitioning with minimal risk to my existing data and what kind of filesystem do you recommend? I would prefer a console-based guide but unfortunately all the material I found on the web is oriented towards partitioning the main (bootable) disk and not an external fuseblk filesystem used only for passive data.

  • Audio server with best API?

    - by Wintermute
    I'm a web dev, working in a small studio with a couple of other devs and some crayon-munchers (or, "designers"). Like all the best and trendiest creative studios, we have tunes. Our tunes consists of a set of speakers that whoever wants to can plug into their machine, and DJ their little socks off via iTunes, Spotify, VLC or whatever their music player of choice happens to be. Obviously, this lacks finesse. What we WANT is this: a single, dedicated machine running some sort of audio player (ideally Win-based, but a Linux flavour isn't impossible), that exposes an API. We (ie: me and the other devs) want to write a web-based client onto it, that'll let us remotely do all sorts of funky stuff like generating on-the-fly genre-based playlists, and voting for tracks, and making tea. My question - and please forgive me if this isn't the place for such a question, I was going to ask on Stackoverflow but that didn't seem right either - is this: what's the best player to start with? What can do all of this? I know VLC can function as a streaming server, but know nothing of any API it may have. I'd rather chop my pinky off than use iTunes, but if it does what we want, then... Anyhow, thanks for reading. All comments and suggestions gratefully received.

  • Windows 7 using llt for ipv6

    - by Seoman
    The question asked below is based on the specific implementations of the Os not the RFC. Looking on a way to be able to assign a fixed ip address to a host, before it boots I found that Centos 6 works fine with no modifications and Windows 7 does not work at all. As defined in enter link description here exists 3 valid ways of generate a DUID: 1 Link-layer address plus time 2 Vendor-assigned unique ID based on Enterprise Number 3 Link-layer address Looking at the centos, that works fine, I can see the following autogenerated DUID: option dhcp6.client-id 0:1:0:1:19:60:25:f1:52:54:0:6b:b9:9e; and the MAC address for this host is: ifconfig eth1 | grep HWaddr eth1 Link encap:Ethernet HWaddr 52:54:00:6B:B9:9E As you can see, the DUID containts the MAC address. I can assign a fixed ip address to this host by including an entry on my dhcp server similar to: host vm { hardware ethernet 52:54:00:6B:B9:9E; fixed-address6 2001:db8:0:1::200; if packet(0,1) = 1 { log(debug,"VM Request match!"); } } And the Centos 6 gets his ip. On the windows side, I faced a common problem explained on this other link enter link description here As summary, Win7 uses the option 2 of the DUID generation or a variation of this one. On the link explains how to move it to a llt (link layer + time) but is not working fine. If I modify the DUID to one that looks like the one generated on Centos (but with the right MAC) it works as expected. Question 1 How Can I change the DUID generation for Windows 7 to be based on MAC as Centos 6 does? Thanks

  • How can I make my Super keys (Windows Key) behave more like Ctrl/Alt/Shift in Linux

    - by deltaray
    After using the Ctrl + "arrow keys" for 13 years to switch virtual desktops in X windows, I've been convinced recently to change to using the Super keys instead (the windows key and the context menu key, which I've remapped). This all works fine for the most part. However, something is still picking up the key events that these keys are sending as if they are a normal alphanumeric like key. For example, I first noticed this in Google Docs spreadsheet that if I press the windows key alone over top of a cell, that it starts editing that cell. It doesn't insert anything, it just sends a key event that Firefox sees and starts editing the cell. This caused problems on a collaborative document I was working on as the way Google docs works, it led to me accidentally erasing the data in a few fields before I realised what was going on. I like using the super keys, but I want them to behave more like a Ctrl or Alt key does in that its a modifier key and doesn't send anything until a second key is pressed. My setup is the following: Ubuntu 10.10 XFCE 4 Microsoft Natural Ergo 4000 keyboard (with the logo scratched out) The following is my .Xmodmap file: remove Lock = Caps_Lock keycode 66 = Escape ! The below maps my other windows context menu key. keycode 135 = Super_R Edit: As requested, here is the relevant output from xev for a keypress and keyrelease of my Super_L (left windows key) KeyPress event, serial 34, synthetic NO, window 0x8200001, root 0x15d, subw 0x0, time 2428849342, (177,174), root:(182,228), state 0x10, keycode 133 (keysym 0xffeb, Super_L), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 34, synthetic NO, window 0x8200001, root 0x15d, subw 0x0, time 2428849430, (177,174), root:(182,228), state 0x50, keycode 133 (keysym 0xffeb, Super_L), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False

  • Does Google sometimes ignore "special" characters, possibly depending on your location or font type settings? [closed]

    - by RLH
    TLDR Google tends to ignore special characters in my search strings. Is there anything that I can do about it and is it, possibly, happening because Google makes certain assumptions based off of my default text-encoding settings and my location? I just posted this question over at StackOverflow. I had found a C preprocessor that I'd never seen before. As I should have done, I Googled it and tried to find out further information. I attempted various search terms which were all variations of "C Operator ##" (some times with and some times without the double-quotes.) Google didn't bring back anything of use so I posted my question on SO. As you can see from the comments, someone mentioned a search string (ironically one which I did try to search) and stated that I could have even hit the "I'm feeling lucky" button and have gotten my answer. The problem is I did search that, and the results that I received were far more basic and even after following the top results and searching the resulting pages, I could find nothing referencing the string "##". I'm not posting this question to complain but it does provide an empirical example of something I've seen before that really bugs me-- Google often ignores special characters in my search strings and the results are often useless. As a developer I often need to search for string values containing non-alphanumeric characters. Some characters (like the underscore or hyphen) can be used without trouble. However, other characters (such as the ampersand, carat, tilde and pound sign) are often ignored in my query strings. Is there a way to prevent this from happening so that I can get meaningful results from Google? NOTE I stay logged into Google and I live in the US. I wonder if Google detects some form of text-encoding setting or derives my results based off of certain, localized text-based assumptions. Regardless, I would like to for Google to search for what I give it. Is there anything that I can do to improve my results?

  • Windows 8 not shutting down properly

    - by Patrick
    Since installing Windows 8, the computer hasn't been shutting down properly. When selecting to power down, the PC quickly displays the shutting down screen, the monitor powers off, and the computer remains on but unresponsive. After about 5 minutes, the computer will turn off. Upon booting into windows again, I am informed that Windows didn't properly shut down. I'm running a fast SSD, and it's a clean install of Windows 8, so there's no way Windows is taking that time to do some sort of hibernate on shutdown or whatever - not to mention the error when entering Windows the next time. This happens on every shut down. Restart works as expected. EDIT: Formatting again didn't work. Fails regardless of drivers installed. Event viewer Always these two messages in close succession: Error (event ID 6008): The previous system shutdown at 7:45:21 PM on ?27/?10/?2012 was unexpected. Critical (kernel power, event ID 41): The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

  • Google Chrome on Linux not using ALSA for sound

    - by DarkMoon
    On my laptop, I've got an .asoundrc file that outputs sound to my USB headset. This works fine for SMplayer and Firefox. However, Google Chrome (at least, Flash-based and HTML5-based videos and HTML5-based audio in Chrome) plays through the laptop speakers instead. I've tried running Chrome from a command-line, hoping there would be some helpful output, but no such luck. I've tried looking through Google for whether Chrome even uses ALSA, or if it uses something else, but I have been unsuccessful in this. This question seems to be the same issue, but no suggestion was made. Anyone have any ideas? I'm running Gentoo with a 3.10.17 kernel, 1.0.27 ALSA utils, 2.6.5 FVWM, and 36.0.1985.143 Chrome. If you need more info, please let me know. EDIT: I've configured the USB headset as the default ALSA device. Volume levels for both headset and onboard are set and un-muted using alsamixer. My .asoundrc file is as follows. ctl.!default { type hw card Headset } pcm.dmixer { type dmix ipc_key 1024 slave { pcm { type hw card Headset } period_size 1024 buffer_size 4096 } bindings { 0 0 1 1 } } pcm.!default { type plug slave.pcm dmixer }

  • Faster caching method

    - by pataroulis
    I have a service that provides HTML code which at some point it is not updated anymore. The code is always generated dynamically from a database with 10 million entries so each HTML code page rendering searches there for say 60 or 70 of those entries and then renders the page. So, for those expired pages, I want to use a caching system which will be VERY simple (like just enter a record with the rendered HTML and (if I need) remove it). I tried to do it file-based but the search for the existence of a file and then passing it through php to actually render it , seems like too much for what I want to do. I was thinking of doing it on mysql with a table with MEDIUMBLOBs (each page is around 100k). It would hold about 150000 such records (for now, at least). My question is: Would it be faster to let mysql do the lookup of the file and the passing to php or is the file-based approach faster? The lookup code for the file based version looks like this: $page = @file_get_contents(getCacheFilename($pageId)); if($page!=NULL) { echo $page; } else { renderAndCachePage($pageId); } which does one lookup whether it finds the file or not. The mysql table would just have an ID (the page id) and the blob entry. The disk of the system is a simple SATA raid 1 , the mysql daemon can grab up to 2.5GB of memory (i have a proxy running too, eating the rest of the 16GB of the machine. ) In general the disk is quite busy already. My not using PEAR cache, is because I think (please feel free to correct me on this) it adds overhead I do not need because the page rendering code is called about 2M times per day and I wouldn't want to go through the whole code each time (and yes, I have eaccelerator to cache the code too). Any pointer to what direction I should go, would be greatly welcome. Thanks!

  • moving from WinXP to WinServer in VmWare

    - by Alex
    I have a Vmware machine for.Net application testing. Current setup: Host OS: win7 Guest OS: Right now the guest OS is Win Xp Pro x64, which runs great with just 1 gigabyte of RAM and 10 gigs of disk space. * This part can be skipped * As I said, there was a program that I needed to test, but unfortunately, by default, Vmware installs crappy display drivers(called SVGA II) on XP machines and there is NO way to upgrade them! This resulted in my program's error (the program used SlimDX (DirectX wrapper) to do some stuff..). Eventually I found out that display drivers most certainly is the problem. For example, Windows 7 virtual machine uses SVGA 3D drivers and I have NO problems running my SlimDX-based program. Now, regarding Windows Server 2008! Apparently, WDDM driver is supported by WS2008, which means that I'll be able to install SVGA 3D and to test my DX apps. * end of skip * The questions are: Will WS2008 be as smooth with just 1 gig of RAM just like Win XP was? Will 10 gigs of HDD be enough? Or the server requires more? Will I be able to install .Net ver. 4 on WS2008? Are there any limitations that I need to be aware of as a .Net programmer? EDIT: I was hoping that WS2008 is XP-based, not Vista-vased/W7-based. In comparison, W7 virtual machine with 2 gigs of RAM and 2 proc cores nearly kills my Host OS. Whereas, WinXp runs extremely fast even with 1 core and 1 gig of RAM. That's the main reason why I want to try WS2008..

  • NSFetchedResultsController crashing on performFetch: when using a cache

    - by Oliver
    I make use of NSFetchedResultsController to display a bunch of objects, which are sectioned using dates. On a fresh install, it all works perfectly and the objects are displayed in the table view. However, it seems that when the app is relaunched I get a crash. I specify a cache when initialising the NSFetchedResultsController, and when I don't it works perfectly. Here is how I create my NSFetchedResultsController: - (NSFetchedResultsController *)results { // If we are not nil, stop here if (results != nil) return results; // Create the fetch request, entity and sort descriptors NSFetchRequest *fetch = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Event" inManagedObjectContext:self.managedObjectContext]; NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"utc_start" ascending:YES]; NSArray *descriptors = [[NSArray alloc] initWithObjects:descriptor, nil]; // Set properties on the fetch [fetch setEntity:entity]; [fetch setSortDescriptors:descriptors]; // Create a fresh fetched results controller NSFetchedResultsController *fetched = [[NSFetchedResultsController alloc] initWithFetchRequest:fetch managedObjectContext:self.managedObjectContext sectionNameKeyPath:@"day" cacheName:@"Events"]; fetched.delegate = self; self.results = fetched; // Release objects and return our controller [fetched release]; [fetch release]; [descriptor release]; [descriptors release]; return results; } These are the messages I get when the app crashes: FATAL ERROR: The persistent cache of section information does not match the current configuration. You have illegally mutated the NSFetchedResultsController's fetch request, its predicate, or its sort descriptor without either disabling caching or using +deleteCacheWithName: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'FATAL ERROR: The persistent cache of section information does not match the current configuration. You have illegally mutated the NSFetchedResultsController's fetch request, its predicate, or its sort descriptor without either disabling caching or using +deleteCacheWithName:' I really have no clue as to why it's saying that, as I don't believe I'm doing anything special that would cause this. The only potential issue is the section header (day), which I construct like this when creating a new object: // Set the new format [formatter setDateFormat:@"dd MMMM"]; // Set the day of the event [event setValue:[formatter stringFromDate:[event valueForKey:@"utc_start"]] forKey:@"day"]; Like I mentioned, all of this works fine if there is no cache involved. Any help appreciated!

  • Error handling in VS/C# build events.

    - by ProfK
    I have just written a small utility to be used in a pre-build event. The utilty works fine when run as standalone, but does nothing when used in the build event. Is there a standard way of noticing and dealing with error conditions in build events, or is that the domain of more advanced build control?

  • Android Spinner selection

    - by Arutha
    The OnItemSelectedListener event handler gets called both when a spinner selection is changed programmatically, and when a user physically clicks the spinner control. Is is possible to determine if an event was triggered by a user selection somehow? Or is there another way to handle spinner user selections?

    Has anybody had any luck getting FullCalendar to work with jQuery's ThickBox? When somebody clicks on a FullCalendar event, I would like the event details to open into a ThickBox window. Any idea how to get them to work together?

  • Qt vs .NET - plz no n00bs who don't know wtf they're talking about [closed]

    - by Pirate for Profit
    Man in all these Qt vs. .NET discussions 90% these people don't know WTF they're talking about. Trying to get a real comparison chart going before we embark on a major fucking project. And yes I'm drunk, and yes I use cocaine. Event Handling In Qt the event handling system you just emit signals when something cool happens and then catch them in slots, for instance emit valueChanged(int percent, bool something); and void MyCatcherObj::valueChanged(int p, bool ok){} blocking them and disconnecting them when needed, doing it across threads... once you get the hang of it, it just seems a lot more natural and intuitive than the way the .NET event handling is set up (you know, object sender, CustomEventArgs e). And I'm not just talking about syntax, because in the end the .NET delegate crap is the bomb. I'm also talking about in more than just reflection (because, yes, .NET obviously has much stronger reflection capabilities). I'm talking about in the way the system feels to a human being. Qt wins hands down i m o. Basically, the footprints make more sense and you can visualize the project easier without the clunky event handling system. I wish I could it explain it better. The only thing is, I do love some of the ease of C# compared to C++ and .NET's assembly architecture. That is a big bonus for modular projects, which are a PITA to do in C++. Database Ease of Doing Crap Also what about datasets and database manipulations. I think .net wins here but I'm not sure. Threading/Conccurency How do you guys think of the threading? In .NET, all I've ever done is make like a list of master worker threads with locks. I like QConcurrentFramework, you don't worry about locks or anything, and with the ease of the signal slot system across threads it's nice to get notified about the progress of things. Memory Usage Also what do you think of the overall memory usage comparison. Is the .NET garbage collector pretty on the ball and quick compared to the instantaneous nature of native memory management? Or does it just let programs leak up a storm and lag the computer then clean it up when it's about to really lag? However, I am a n00b who doesn't know what I'm talking about, please school me on the subject.

  • jquery prevent paste to iframe designmode from msword

    - by naugtur
    Hi. I've seen some questions on catching paste event. This looks helpful. But I want to prevent paste from happening when the pasted content is not plaintext, but comes from msword or other wysiwyg editor. Anybody got any experience on that? I suppose I should catch the event and look for some specific tags in the clipboard. Any known content that msie adds everytime?

  • Right-click context menu for Java JTree?

    - by arcanex
    I'm trying to implement pop-up menus in Java JTree. I've sub-classed DefaultTreeCellRenderer (to change node appearance) and DefaultTreeCellEditor (to create Components to attach event listeners to, since apparently the Components that DefaultTreeCellRenderer.getTreeCellRendererComponent() returns can't do it?). I don't really want to "edit" the nodes, just be able to pop-up a menu when a node gets right-clicked, but this is the only way I can think of doing it right now... Below is the code that I have so far-- I'm just trying to figure out how to capture MouseEvents. It sort of works, but badly. What's a better way to accomplish what I'm trying to do here? private class My_TreeCellRenderer extends DefaultTreeCellRenderer { My_TreeCellRenderer() { super (); } public Component getTreeCellRendererComponent(JTree tree, Object value, boolean selected, boolean expanded, boolean leaf, int row, boolean hasFocus) { super.getTreeCellRendererComponent(tree, value, selected, expanded, leaf, row, hasFocus); // set label text and tool tips setText(((My_Object)value).getTreeLabel()); setToolTipText(((My_Object)value).getTreeToolTip()); return this; } } private class My_TreeCellEditor extends DefaultTreeCellEditor { private MouseAdapter ma; My_TreeCellEditor(JTree tree, DefaultTreeCellRenderer renderer) { super (tree, renderer); ma = new MouseAdapter() { public void mousePressed(MouseEvent e) { if (e.isPopupTrigger()) { System.out.println("My Popup"); } } public void mouseReleased(MouseEvent e) { if (e.isPopupTrigger()) { System.out.println("My Popup"); } } }; } public Component getTreeCellEditorComponent(JTree tree, Object value, boolean selected, boolean expanded, boolean leaf, int row) { String src_filename = null; // return non-editing component Component c = renderer.getTreeCellRendererComponent(tree, value, selected, expanded, leaf, row, true); // add mouse listener if it's not listening already MouseListener mouseListeners[] = c.getMouseListeners(); int i; for (i=0; i < mouseListeners.length && mouseListeners[i] != ma; i++); if (i >= mouseListeners.length) c.addMouseListener(ma); return c; } protected boolean canEditImmediately(EventObject event) { if (event instanceof MouseEvent && ((MouseEvent)event).getClickCount() == 1) return true; else return false; } }
