  • socket.error: [Errno 10013] An attempt was made to access a socket in a way forbidden by its access

    - by Sean Ochoa
    Hello all. I'm trying to create a custom TCP stack using Python 2.6.5 on Windows 7 to serve valid http page requests on port 80 locally. But, I've run into a snag with what seems like Windows 7 tightened up security. This code worked on Vista. Here's my sample code: import SocketServer class MyTCPHandler(SocketServer.BaseRequestHandler): def handle(self): headerText = """HTTP/1.0 200 OK Date: Fri, 31 Dec 1999 23:59:59 GMT Content-Type: text/html Content-Length: 1354""" bodyText = "<html><body>some page</body></html>" self.request.send(headerText + "\n" + bodyText) if __name__ == "__main__": HOST, PORT = "localhost", 80 server = SocketServer.TCPServer((HOST, PORT), MyTCPHandler) server.serve_forever() C:\pythonpython TestServer.py Traceback (most recent call last): File "TestServer.py", line 19, in server = SocketServer.TCPServer((HOST, PORT), MyTCPHandler) File "C:\Python26\lib\SocketServer.py", line 400, in init self.server_bind() File "C:\Python26\lib\SocketServer.py", line 411, in server_bind self.socket.bind(self.server_address) File "", line 1, in bind socket.error: [Errno 10013] An attempt was made to access a socket in a way forbidden by its access permissions How exactly do I get this to work on Windows 7?

  • Network Error: no buffer space available

    - by braindump
    After some time of running fine, one of our Windows XP SP3 machines does not open some(!) new TCP/IP connections anymore. Putty says "Network Error: no buffer space available", IE won't open any new connections but e.g. network drive mappings still work, even new ones can be established. netstat does not show more open connections that usual, ping and dns lookups work fine. Any hints?

  • RDS installation failure on 2012 R2 Server Core VM in Hyper-V Server

    - by Giles
    I'm currently installing a test-bed for my firms Infrastructure replacement. 10 or so Windows/Linux servers will be replaced by 2 physical servers running Hyper-V server. All services (DC, RDS, SQL) will be on Windows 2012 R2 Server Core VMs, Exchange on Server 2012 R2 GUI, and the rest are things like Elastix, MailArchiver etc, which aren't part of the equation thus far. I have installed Hyper-V server on a test box, and sucessfully got two virtual DC's running, SQL 2014 running, and 8.1 which I use for the RSAT tools. When trying to install RDS (The old fashioned kind, not the newer VDI(?) style), I get a failed installation due to the server not being able to reboot. A couple of articles have said not to do it locally, so I've moved on. Sitting at the Powershell prompt on the Domain Controller or SQL server (Both Server Core), I run the following commands: Import-Module RemoteDesktop New-SessionDeployment -ConnectionBroker "AlstersTS.Alsters.local" -SessionHost "AlstersTS.Alsters.local" The installation begins, carries on for 2 or 3 minutes, then I receive the following error message: New-SessionDeployment : Validation failed for the "RD Connection Broker" parameter. AlstersTS.Alsters.local Unable to connect to the server by using WindowsPowerShell remoting. Verify that you can connect to the server. At line:1 char:1 + NewSessionDeployment -ConnectionBroker "AlstersTS.Alsters.local" -SessionHost " ... + + CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException + FullyQualifiedErrorID : Microsoft.PowerShell.Commands.WriteErrorException,New-SessionDeployment So far, I have: Triple, triple checked syntax. Tried various other commands, and a script to accomplish the same task. Checked DNS is functioning as it should. Checked to the best of my knowledge that AD is working as it should. Checked that the Network Service has the needed permissions. Created another VM and placed the two roles on different servers. Deleted all VMs, started again with a new domain name (Lather, rinse, repeat) Performed the whole installation on a second physical box running Hyper-V Server Pleaded with it Interestingly, if I perform the installation via a GUI installation, the thing just works! Now I know I could convert this to a Server Core role after installation, but this wouldn't teach me what was wrong in the first instance. I've probably got 10 pages through various Google searches, each page getting a little less relevant. The closest matches seem to have good information, but it doesn't seem to be the fix for my set-up. As a side note, I expected to be able to "tee" or "out-file" the error message into a text file, but couldn't get that to work either, so I've typed in the error message manually. Chaps, any suggestions, from the glaringly obvious, to the long-winded and complex? Thanks!

  • RoboCopy Log File Analysis

    - by BobJim
    Is it possible to analyse the log text file outputted from RoboCopy and extract the lines which are defined as "New Dir" and "Extra Dir"? I would like the line from the log contain all the details returned regarding this "New Dir" or "Extra Dir" The reason for completing this task is to understand how two folder structures have change over time. One version has been kept internally at the parent company, the second has been used by a consultancy. For your information I am using Windows 7.

  • Ndk-build: CreateProcess: make (e=87): The parameter is incorrect

    I get an error when build static lib with NDK on Windows platform: process_begin: CreateProcess( "PATH"\android-ndk-r8b\toolchains\arm-linux-androideabi-4.6\prebuilt\windows\bin\arm-linux-androideabi-ar.exe, "some other commands" ) failed. make (e=87): The parameter is incorrect. make: *** [obj/local/armeabi-v7a/staticlib.a] Error 87 make: *** Waiting for unfinished jobs....

How I can solve this issue?

  • Vista install works on one computer, but bluescreens another (on which Vista is known to work)

    - by Ken
    I hope my explanations make some sense -- please ask for clarification if they don't. I had a computer running Windows Vista (Ultimate, 64-bit). All was well! Then one day there was a nasty power surge at the office, and it died. (We didn't have surge protectors at the office, unfortunately. I assumed our lines were conditioned elsewhere, or was not an issue here. Oops.) After some testing, it was determined that the PSU, motherboard, and RAM were bad. While waiting for new hardware to arrive, I put my hard disk in a spare PC which had identical parts (mobo/CPU/RAM/PSU/video). Everything worked perfectly. The only way I could even tell it wasn't my computer is because Vista asked to re-activate itself with the new hardware, which worked fine, too. So the hard disk seems OK. Then the new parts arrived. The old motherboard model is no longer manufactured, so it's a new one with the same CPU/RAM/videocard/etc. slots. The PSU is also new, while the RAM I'm using is from the spare PC mentioned above. When I put it together and tried booting with my old hard disk, it starts to boot Windows, and then (fairly early in the process) gives a bluescreen and immediately reboots (so I can't see whatever the bluescreen is trying to tell me). I tried "safe mode", which also bluescreened. I tried booting the Vista DVD and running the repair utility, which found a Vista install, confirmed that it would not boot, and, eventually, declared that it was unable to repair it. I installed Vista fresh on a new hard disk, with the new mobo/etc., and it works perfectly. (That's what I'm running now.) I've also booted a Linux CD here, which ran great, and I've run Memtest86+ for a while, which found no errors. So all the hardware apart from the old hard disk seems OK, too. I don't think the problem is with my old Vista hard disk, since I used that with another mobo/CPU just fine. I don't think it's any other part of the new hardware, since I'm able to use it (and test it) with no trouble. It's just the combination of my old Vista install plus the new PC hardware that's not happy. I can get my data off my old hard disk and onto my new hard disk, and reinstall my apps, but it would be nice if I could fix things so I could continue to use my old hard disk as before. The latest hypothesis I've heard is that Vista had trouble with the new hardware (i.e., motherboard), but we have no idea what to do about that (except Safe Mode, which didn't work). Suggestions? Hypotheses for what's not right about this combination of Vista install and motherboard? Thanks!

  • Where do all the old programmers go?

    - by Tony Lambert
    I know some people move over to management and some die... but where do the rest go and why? One reason people change to management is that in some companies the "Programmer" career path is very short - you can get to be a senior programmer within a few years. Leaving no way to get more money but to become a manager. In other companies project managers and programmers are parallel career paths so your project manager can be your junior. Tony

  • Coding Competition, language agnostic guidelines?

    - by Miau
    Hi there: I might be doing a coding competition soon, I was wondering if anyone made one and what where the guidelines/ process. I'd like to make the competition appealing to all devs, and I m trying to come up with ideas as to how. the scenario is: There is an event running and we(of the coding competition) will have a room that we can use (either to code or for questions, etc), however, ideally the task for the competition should be assignet and they should eb able to go and do other things, if they are so inclined. what i wonder is what kind of challenges to give, and most importantly, what is the criteria to "win" teaching and learning good coding standards takes a looong time, and I d like to think that if you ve been coding for longer you ll do things right and quick... but in a competition, you would be cutting corners... I would really appreciate your input on this

  • Socket error 10052 on UDP socket

    - by Jesper
    We have a .NET 2.0 desktop application which sends and receives network packets over UDP. Several users have reported an occasional socket error 10052 which happens when the code calls socket.BeginReceiveFrom on a the UDP socket. What does this mean? The official MS documentation for socket error 10052 says - quote: "WSAENETRESET (10052) Network dropped connection on reset . The connection has been broken due to keep-alive activity detecting a failure while the operation was in progress. It can also be returned by setsockopt if an attempt is made to set SO_KEEPALIVE on a connection that has already failed." This just doesn't make much sense for a UDP socket since UDP is a connectionless protocol. I know that another close error code 10054 in connection with UDP sockets means that an ICMP message "Port Unreachable" was received, and I am wondering if 10052 might map to another ICMP message? I have googled this for months, read network books, etc. but can't find anything. Please help - what does socket error 10052 on a UDP socket mean? Thanks in advance

  • Getting the submatrix with maximum sum?

    - by guirgis
    With the help of the Algorithmist and Larry and a modification of Kadane's Algorithm, here is my solution: int dim = matrix.length; //computing the vertical prefix sum for columns int[][] ps = new int[dim][dim]; for (int i = 0; i < dim; i++) { for (int j = 0; j < dim; j++) { if (j == 0) { ps[j][i] = matrix[j][i]; } else { ps[j][i] = matrix[j][i] + ps[j - 1][i]; } } } int maxSoFar = 0; int min , subMatrix; //iterate over the possible combinations applying Kadane's Alg. //int toplefti =0, topleftj=0, bottomrighti=0, bottomrightj=0; for (int i = 0; i < dim; i++) { for (int j = i; j < dim; j++) { min = 0; subMatrix = 0; for (int k = 0; k < dim; k++) { if (i == 0) { subMatrix += ps[j][k]; } else { subMatrix += ps[j][k] - ps[i-1][k]; } if(subMatrix < min){ min = subMatrix; } if((subMatrix - min) > maxSoFar){ maxSoFar = subMatrix - min; } } } } The only problem left is to determine the submatrix elements, i mean the top left and the bottom right corners. I managed to do this in one dimensional case. Any suggestions?

  • Why do many software projects fail today?

    - by TomTom
    As long as there are software projects, the world is wondering why they fail so often. I would like to know if there is a list or something equivalent which shows how many software projects fail today. Would be nice if there would be a comparison over the last 20 - 30 years. You can also add your top reason why a software project fails. Mine is "Requirements are poor or not even existing." which includes also "No (real) customer / user involved". EDIT: It is nearly impossible to clearly define the term "fail". Let's say that fail means: The project was more than 10% over budget and time. In my opinion the 10% + / - is a good range for an offer / tender. EDIT: Until now (Feb 11) it seems that most posters agree that a fail of the project is basically a failure of the project management (whatever fail means). But IMHO it comes out, that most developers are not happy with this situation. Perhaps because not the manager get penalized when a project was not successful, but the lazy, incompetent developer teams? When I read the posts I can also hear-out that there is a big "gap" between the developer side and the managment side. The expectations (perhaps also the requirements) seem to be so different, that a project cannot be successful in the end (over time / budget; users are not happy; not all first-prio features implemented; too many bugs because developers were forced to implement in too short timeframes ...) I',m asking myself: How can we improve it? Or do we have the possibility to improve it? Everybody seems to be unsatisfied with the way it goes now. Can we close the gap between these two worlds? Should we (the developers) go on strike and fight for "high quality reqiurements" and "realistic / iteration based time shedules"? EDIT: Ralph Westphal and Stefan Lieser have founded a new "community" called: Clean-Code-Developer. The aim of the group is to bring more professionalism into software engineering. Independently if a developer has a degree or tons of years of experience you can be part of this movement. Clean Code Developers live principles like SOLID every day. A professional developer is the biggest reviewer of his own work. And he has an internal value system which helps him to improve and become better. Check it out on: Clean Code Developer EDIT: Our company is doing at the moment a thing called "Application Development and Maintenance Benchmarking". This is a service offered by IBM to get a feedback from someone external on your software engineering process quality etc. When we get the results, I will tell you more about it.

  • Please explain some of Paul Graham's points on LISP

    - by kunjaan
    I need some help understanding some of the points from Paul Graham's article http://www.paulgraham.com/diff.html A new concept of variables. In Lisp, all variables are effectively pointers. Values are what have types, not variables, and assigning or binding variables means copying pointers, not what they point to. A symbol type. Symbols differ from strings in that you can test equality by comparing a pointer. A notation for code using trees of symbols. The whole language always available. There is no real distinction between read-time, compile-time, and runtime. You can compile or run code while reading, read or run code while compiling, and read or compile code at runtime. What do these points mean How are they different in languages like C or Java? Do any other languages other than LISP family languages have any of these constructs now?

  • iPhone - archiving array of custom objects

    - by Dylan
    I've been trying for hours and I cannot solve this problem. I'm making an app that saves unfinished Chess Games, so I'm trying to write an array to a file. This is what the array is, if it makes sense: -NSMutableArray savedGames --GameSave a ---NSMutableArray board; ----Piece a, b, c, etc. -----some ints ---NSString whitePlayer, blackPlayer; ---int playerOnTop, turn; --GameSave b ---NSMutableArray board; ----Piece a, b, c, etc. -----some ints ---NSString whitePlayer, blackPlayer; ---int playerOnTop, turn; etc. And these are my NSCoding methods: GameSave.m - (void)encodeWithCoder:(NSCoder *)coder { [coder encodeObject:whitePlayer forKey:@"whitePlayer"]; [coder encodeObject:blackPlayer forKey:@"blackPlayer"]; [coder encodeInt:playerOnTop forKey:@"playerOnTop"]; [coder encodeInt:turn forKey:@"turn"]; [coder encodeObject:board forKey:@"board"]; } - (id)initWithCoder:(NSCoder *)coder { self = [[GameSave alloc] init]; if (self != nil) { board = [coder decodeObjectForKey:@"board"]; whitePlayer = [coder decodeObjectForKey:@"whitePlayer"]; blackPlayer = [coder decodeObjectForKey:@"blackPlayer"]; playerOnTop = [coder decodeIntForKey:@"playerOnTop"]; turn = [coder decodeIntForKey:@"turn"]; } return self; } Piece.m - (void)encodeWithCoder:(NSCoder *)coder { [coder encodeInt:color forKey:@"color"]; [coder encodeInt:piece forKey:@"piece"]; [coder encodeInt:row forKey:@"row"]; [coder encodeInt:column forKey:@"column"]; } - (id)initWithCoder:(NSCoder *)coder { self = [[Piece alloc] init]; if (self != nil) { color = [coder decodeIntForKey:@"color"]; piece = [coder decodeIntForKey:@"piece"]; row = [coder decodeIntForKey:@"row"]; column = [coder decodeIntForKey:@"column"]; } return self; } And this is the code that tries to archive and save to file: - (void)saveGame { ChessSaverAppDelegate *delegate = (ChessSaverAppDelegate *) [[UIApplication sharedApplication] delegate]; [[delegate gameSave] setBoard:board]; NSMutableArray *savedGames = [NSKeyedUnarchiver unarchiveObjectWithFile:[self dataFilePath]]; if (savedGames == nil) { [NSKeyedArchiver archiveRootObject:[delegate gameSave] toFile:[self dataFilePath]]; } else { [savedGames addObject:[delegate gameSave]]; [NSKeyedArchiver archiveRootObject:savedGames toFile:[self dataFilePath]]; } } - (NSString *)dataFilePath { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; return [documentsDirectory stringByAppendingPathComponent:@"gameSaves.plist"]; } Sorry, here's the problem: After setting some breakpoints, an error is reached after this line from -saveGame: [NSKeyedArchiver archiveRootObject:savedGames toFile:[self dataFilePath]]; And this is what shows up in the console: 2010-05-11 17:04:08.852 ChessSaver[62065:207] *** -[NSCFType encodeWithCoder:]: unrecognized selector sent to instance 0x3d3cd30 2010-05-11 17:04:08.891 ChessSaver[62065:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFType encodeWithCoder:]: unrecognized selector sent to instance 0x3d3cd30' 2010-05-11 17:04:08.908 ChessSaver[62065:207] Stack: ( 32339035, 31077641, 32720955, 32290422, 32143042, 238843, 25827, 238843, 564412, 342037, 238843, 606848, 17686, 2733061, 4646817, 2733061, 3140430, 3149167, 3144379, 2837983, 2746312, 2773089, 41684313, 32123776, 32119880, 41678357, 41678554, 2777007, 9884, 9738 ) If it matters, -saveGame is called from a UIBarButton in a navigation controller. Any help is appreciated, thanks.

  • netsh wlan add profile not importing encrypted passphrase

    - by sirlancelot
    I exported a wireless network connection profile from a Windows 7 machine correctly connected to a WiFi network with a WPA-TKIP passphrase. The exported xml file shows the correct settings and a keyMaterial node which I can only guess is the encrypted passphrase. When I take the xml to another Windows 7 computer and import it using netsh wlan add profile filename="WiFi.xml", it correctly adds the profile's SSID and encryption type, but a balloon pops up saying that I need to enter the passphrase. Is there a way to import the passphrase along with all other settings or am I missing something about adding profiles? Here is the exported xml with personal information removed: <?xml version="1.0"?> <WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1"> <name>[removed]</name> <SSIDConfig> <SSID> <hex>[removed]</hex> <name>[removed]</name> </SSID> <nonBroadcast>false</nonBroadcast> </SSIDConfig> <connectionType>ESS</connectionType> <connectionMode>auto</connectionMode> <autoSwitch>false</autoSwitch> <MSM> <security> <authEncryption> <authentication>WPAPSK</authentication> <encryption>TKIP</encryption> <useOneX>false</useOneX> </authEncryption> <sharedKey> <keyType>passPhrase</keyType> <protected>true</protected> <keyMaterial>[removed]</keyMaterial> </sharedKey> </security> </MSM> </WLANProfile> Any help or advice is appreciated. Thanks. Update: It seems if I export the settings using key=clear, the passphrase is stored in the file unprotected and I can import the file on another computer without issue. I've updated my question to reflect my findings.

  • Group Policy: Block access to \\localhost\C$

    We have a restricted Windows 7 computer that hides and prevents non-admin users from accessing the C Drive. However, they are able to circumvent this by typing the following into Explorer: \\localhost\C$ How can I disable this path but allow other UNC paths. For example they are allowed to access a shared folder on a different computer. eg. \\192.168.2.1\SharedTransfer Note: Simply Enabling the Group Policy: Remove Run menu from Start Menu will not work as this blocks all UNC paths.
