  • Unable to connect to Samba printer

    - by user127236
    I have a headless Ubuntu 12.04 server for files and printers. It shares files via Samba just fine. However, the HP PSC-750xi connected to the server via USB is not accessible from my Ubuntu 12.04 laptop. I can browse for it in the Printing control panel, but any attempt to authenticate my ID to the printer with my user credentials results in the error "This print share is not accessible". I have included the Samba smb.conf file below. Any help appreciated. Thanks... JGB # # Sample configuration file for the Samba suite for Debian GNU/Linux. # # # This is the main Samba configuration file. You should read the # smb.conf(5) manual page in order to understand the options listed # here. Samba has a huge number of configurable options most of which # are not shown in this example # # Some options that are often worth tuning have been included as # commented-out examples in this file. # - When such options are commented with ";", the proposed setting # differs from the default Samba behaviour # - When commented with "#", the proposed setting is the default # behaviour of Samba but the option is considered important # enough to be mentioned here # # NOTE: Whenever you modify this file you should run the command # "testparm" to check that you have not made any basic syntactic # errors. # A well-established practice is to name the original file # "smb.conf.master" and create the "real" config file with # testparm -s smb.conf.master >smb.conf # This minimizes the size of the really used smb.conf file # which, according to the Samba Team, impacts performance # However, use this with caution if your smb.conf file contains nested # "include" statements.

  • Problems with XP, Office, and PC in general - any ideas?

    - by molecule
    Hi all This may not make a whole lot of sense so pls bear with me... I am about to perform a routine check on one of my user's PC. Some background - the PC has a Xeon processor and 4Gb of RAM and running XP SP3 He has 2xHDD and pagefile is hosted on the secondary HDD (D:) and min/max values are set to 4096. NO pagefile on C: This user has 6 monitors so he has an NVIDIA Quadro NVS440 hosting 4xmonitors and an NVIDIA Quadro NVS290 hosting 2xmonitors. There is a video card driver from NVIDIA which is compatible with both NVS440 and NVS290 and he is on the latest version of that driver. (Note: Make of video cards are different - one is from leadtek and the other from Nvidia) He is a heavy Bloomberg, Outlook, Word, and Excel user and runs two Citrix applications. Other apps are FoxIt PDF and IE. Problems - Outlook and Excel frequently crashes - I am going to perform an Outlook and Excel repair and also check/remove unnecessary addins - will he lose any customizations if I repaired and chose "Restore my shortcuts while repairing" and do not select "Discard my customized settings and restore default settings". Does repair really repair anything? FYI - It stopped crashing ever since i moved a large spreadsheet he has open to his local HDD instead of over the network. This spreadsheet "refreshes" constantly as it is pulling live data to update cells and I suspect it was auto-saving so frequently that it caused crashes if saving over the network. At times, his right click completely fails to respond. His left click works fine but he can't right click on anything in any Window and even on the desktop. Sometimes, he needs to start to close certain applications such as Adobe and the right click will start functioning again. I removed Adobe and installed FoxIt as I figured it was a resource issue but I do not think so as he does have sufficient resources when the problem is happening. Sometimes he can't bring task manager up until he kills certain apps. Definitely sounds like a resource issue but I am not confident that is the root cause. Also not sure if this is related to one of the apps installed but his Start bar flickers (does not completely disappear) intermittently from time to time. The taskbar icons which are hidden appear and then get hidden again as if it was having "fits". I have performed reg scans, malware scans etc but problems do not go away. I am planning to perform sfc /scannow and office repair but would like to know if anyone has any other suggestions. What about setting a "small" pagefile on C:. I have heard that this is recommended and may be the reason why a minidmp file was not generated when he encountered a blue screen. Also, any feedback on his video cards? Do you think different models would cause problems? The drivers seem to work but he only has 2.5Gb out of 4Gb available RAM as I believe the video card chomped up a portion of this. I have recommended creating a new profile for him but due to the amount of customisations he has and the amount of time and effort it will take to get him up and running again, he prefers to bear with the problem than to go down that path. However, at least once a week, his PC acts up and I can't think of any other tools or techniques to rectify his problems. I guess we are at a stage where we just want to "stabilize" things so he won't encounter issues that frequently. Any feedback is very much appreciated.

  • Increase Max Pool Size ERROR when using SYBASE ASE ADO.NET data provider

    - by Brani
    I have made a program in VB.net (visual studio 2003) that connects to a SYBASE ASE database using the ADO.NET data provider. Recently, after a hard disk failure, I restored the program's code from a (rather old) backup. But now the connection fails with a message that does not remind me of anything that I have seen before. Here is the code and the error message: Dim cn As New AseConnection("Data Source='my_server';Port='5000';UID='sa';PWD='my_pwd';Database='my_db';") cn.Open() Error message: Sybase.Data.AseClient.AseException - Cannot allocate more connections. Connection pool is at maximum. Increase Max Pool Size Can anybody help me?

  • RegGetValue vs RegQueryValueEx

    - by baltusaj
    I have a program coded by someone else. It has a function RegGetValue used as: uFuncReturnValue = RegOpenKeyExA( HKEY_LOCAL_MACHINE, acSubKey, NULL, KEY_READ | KEY_WRITE, &hRegistry ); if( uFuncReturnValue != ERROR_SUCCESS ) { printf("Unable to open registry with error %u\n", uFuncReturnValue); exit(EXIT_FAILURE);; } uFuncReturnValue = RegGetValueA( hRegistry, NULL, "\\DosDevices\\C:", RRF_RT_REG_BINARY, NULL, (LPVOID)&structVal, &dwSize ); This block of code works perfectly on Windows 7 but returns error when run on Windows XP (32 bit). As 32-bit xp don't have RegGetValue function so I am trying to make use of RegQueryValueEX but I am having problem in passing arguments to this function. I think it should be used some thing like: uFuncReturnValue = RegQueryValueExA ( hRegistry, "\\DosDevices\\J:", NULL, NULL, (LPBYTE) &structVal, &dwSize ); But something is wrong here because the code compiles successfully but when I execute it I get a message: The program '(128) myProgram.exe: Native' has exited with code 1 (0x1). Can someone help me here please?

  • Blocking access to websites with objective-C / root privileges in objective-C

    - by kvaruni
    I am writing a program in Objective-C (XCode 3.2, on Snow Leopard) that is capable of either selectively blocking certain sites for a duration or only allow certain sites (and thus block all others) for a duration. The reasoning behind this program is rather simple. I tend to get distracted when I have full internet access, but I do need internet access during my working hours to get to a number of work-related websites. Clearly, this is not a permanent block, but only helps me to focus whenever I find myself wandering a bit too much. At the moment, I am using a Unix script that is called via AppleScript to obtain Administrator permissions. It then activates a number of ipfw rules and clears those after a specific duration to restore full internet access. Simple and effective, but since I am running as a standard user, it gets cumbersome to enter my administrator password each and every time I want to go "offline". Furthermore, this is a great opportunity to learn to work with XCode and Objective-C. At the moment, everything works as expected, minus the actual blocking. I can add a number of sites in a list, specify whether or not I want to block or allow these websites and I can "start" the blocking by specifying a time until which I want to stay "offline". However, I find it hard to obtain clear information on how I can run a privileged Unix command from Objective-C. Ideally, I would like to be able to store information with respect to the Administrator account into the Keychain to use these later on, so that I can simply move into "offline" mode with the convenience of clicking a button. Even more ideally, there might be some class in Objective-C with which I can block access to some/all websites for this particular user without needing to rely on privileged Unix commands. A third possibility is in starting this program with root permissions and the reducing the permissions until I need them, but since this is a GUI application that is nested in the menu bar of OS X, the results are rather awkward and getting it to run each and every time with root permission is no easy task. Anyone who can offer me some pointers or advice? Please, no security-warnings, I am fully aware that what I want to do is a potential security threat.

  • How to set foreground Window from Powershell event subscriber action

    - by guillermooo
    I have a FileSystemWatcher instance running in the background of my PoSh session watching for changes to text files. A PoSh event subscriber is attached to this event and, when fired, it launches a console program by calling Start-Process. This program steals de focus from the current foreground window (my PoSh console). Calling SetForegroundWindow from the PoSh event subscriber to return the focus to my PoSh console doesn't work. SwitchToThisWindow does work most of the time, but according to the MSDN docs, it shoulnd't be used. Can I prevent Start-Process from stealing the focus in this situation or set it back from the event subscriber to the window that had it before this event is fired?

  • Android Device Chooser -- device not showing up

    - by mportiz08
    I'm using the android plugin for eclipse, and when I try to run my program using a real device through the android device chooser, my phone is not listed as a device. I have updated eclipse and all of the android packages, but it still isn't showing up. My phone is running 1.6, which is also the target version listed in the eclipse project. Also, the reason I decided to try testing on a real device is because the emulator doesn't seem to be working right anymore when I run my project. The emulator launches, but the program never does. Any ideas? (using windows 7/t-mobile mytouch 3g)

  • Problem setting up Master-Master Replication in MySQL

  • Android: TabHost How To: set new content in existing tabs upon menu button?

    - by Martin D.
    Hello stackoverflow, I recently started Android programming and was working on my first program which displays a historic text document, sectioned by tabs via TabHost. I have limited my program to one activity and merely used setContent in my TabSpec's to switch between different XML views. The document has both unedited and corrected versions of the text for which I have built text views to accommodate. I wanted to implement the standard menu to have buttons to "view corrected" and "view original" and switch the content of the tabs which have changes (without altering the tabs or their indicators). I've read on the TabHost API and there is no way to edit existing tab content with setContent() of TabSpec; and AFAIK TabWidget only affects the actual tabs, not the content that is displayed upon pressing them. I've thought about creating a new class which extended TabHost and super() all of the original methods, while including one more which updated the mTabSpec list. My question would be, how would I update the frameLayout view of a specific tab to display content I specify?

  • Mixing Silverlight-Specific System.Xml.Linq dll with Non-Silverlight System.Xml.Linq dll

    - by programatique
    I have a Logic layer that references Silverlight's System.Xml.Linq dll and a GUI that is in WPF (hence using the non-Silverlight System.Xml.Linq dll). When I attempt to pass an XElement from GUI project to a method in the Logic project, I am getting (basically) "XElement is not of type XElement" errors. To complicate matter, I am unable to edit the Logic layer project. The Non-Silverlight DLL is at: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.Xml.Linq.dll THe Silverlight DLL is at: C:\Program Files (x86)\Microsoft SDKs\Silverlight\v3.0\Libraries\Client\System.Xml.Linq.dll I am new to C# but I'm fairly sure my issue is that I am referencing different DLL's to access the System.Xml.Linq namespace. I attempted to replace my non-Silverlight System.Xml.Linq.dll with the Silverlight's System.Xml.Linq.dll, but received assembly errors. Is there any way to resolve this short of scrapping my WPF GUI project and creating a Silverlight project?

  • Windows Vista/Win7 Privilege Problem: SeDebugPrivilege & OpenProcess

    - by KevenK
    Everything I've been able to find about escalating to the appropriate privileges for my needs has agreed with my current methods, but the problem exists. I'm hoping maybe someone has some Windows Vista/Win7 internals experience that might shine some light where there is only darkness. I'm sure this will get long, but please bare with me. Context: I'm working on an app that requires accessing the memory of other processes on the current machine. This, obviously, requires administrator rights. It also requires SeDebugPrivilege, which I believe myself to be acquiring correctly, although I question if more privileges aren't necessary and thus the cause of my problems. Code has so far worked successfully on all versions of Windows XP, and on my test Vista32 and Win7x64 environments. Process: Program will Always be run with Administrator Rights. This can be assumed throughout this post. Escalating the current process's Access Token to include SeDebugPrivilege rights. Using EnumProcesses to create a list of current PIDs on the system Opening a handle using OpenProcess with PROCESS_ALL_ACCESS access rights Using ReadProcessMemory to read the memory of the other process. Problem: Everything has been working fine during development and my personal testing (including Windows XP 32 & 64, Windows Vista 32, and Windows 7 x64). However, during a test deployment onto both Windows Vista(32-bit) and Windows 7(64-bit) machines of a colleague, there seems to be a privilege/rights problem with OpenProcess failing with a generic Access Denied error. This occurs both when running as a limited User (as would be expected) and also when run explicitly as Administrator (Right-click Run as Administrator and when run from an Administrator level command prompt). However, this problem has been unreproducible for myself in my test environment. I have witnessed the problem first hand, so I trust that the problem exists. The only difference that I can discern between the actual environment and my test environment is that the actual error is occurring when using a Domain Administrator account at the UAC prompt, whereas my tests (which work with no errors) use a local administrator account at the UAC prompt. It appears that although the credentials being used allow UAC to 'run as administrator', the process is still not obtaining the correct rights to be able to OpenProcess on another process. I am not familiar enough with the internals of Vista/Win7 to know what this might be, and I am hoping someone has an idea of what could be the cause. The Kicker: The person who has reported this error, and who's environment can regularly reproduce this bug, has a small application named along the lines of RunWithDebugEnabled which is a small bootstrap program which appears to escalate its own privileges and then launch the executable passed to it (thus inheriting the escalated privileges). When run with this program, using the same Domain Administrator credentials at UAC prompt, the program works correctly and is able to successfully call OpenProcess and operates as intended. So this is definitely a problem with acquiring the correct privileges, and it is known that the Domain Administrator account is an administrator account that should be able to access the correct rights. (Obviously obtaining this source code would be great, but I wouldn't be here if that were possible). Notes: As noted, the errors reported by the failed OpenProcess attempts are Access Denied. According to MSDN documentation of OpenProcess: If the caller has enabled the SeDebugPrivilege privilege, the requested access is granted regardless of the contents of the security descriptor. This leads me to believe that perhaps there is a problem under these conditions either with (1) Obtaining SeDebugPrivileges or (2) Requiring other privileges which have not been mentioned in any MSDN documentation, and which might differ between a Domain Administrator account and a Local Administrator account Sample Code: void sample() { ///////////////////////////////////////////////////////// // Note: Enabling SeDebugPrivilege adapted from sample // MSDN @ http://msdn.microsoft.com/en-us/library/aa446619%28VS.85%29.aspx // Enable SeDebugPrivilege HANDLE hToken = NULL; TOKEN_PRIVILEGES tokenPriv; LUID luidDebug; if(OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, &hToken) != FALSE) { if(LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &luidDebug) != FALSE) { tokenPriv.PrivilegeCount = 1; tokenPriv.Privileges[0].Luid = luidDebug; tokenPriv.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; if(AdjustTokenPrivileges(hToken, FALSE, &tokenPriv, 0, NULL, NULL) != FALSE) { // Always successful, even in the cases which lead to OpenProcess failure cout << "SUCCESSFULLY CHANGED TOKEN PRIVILEGES" << endl; } else { cout << "FAILED TO CHANGE TOKEN PRIVILEGES, CODE: " << GetLastError() << endl; } } } CloseHandle(hToken); // Enable SeDebugPrivilege ///////////////////////////////////////////////////////// vector<DWORD> pidList = getPIDs(); // Method that simply enumerates all current process IDs ///////////////////////////////////////////////////////// // Attempt to open processes for(int i = 0; i < pidList.size(); ++i) { HANDLE hProcess = NULL; hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pidList[i]); if(hProcess == NULL) { // Error is occurring here under the given conditions cout << "Error opening process PID(" << pidList[i] << "): " << GetLastError() << endl; } CloseHandle(hProcess); } // Attempt to open processes ///////////////////////////////////////////////////////// } Thanks! If anyone has some insight into what possible permissions/privileges/rights/etc that I may be missing to correctly open another process (Assuming the executable has been properly "Run as Administrator"ed) on Windows Vista and Windows 7 under the above conditions, it would be most greatly appreciated. I wouldn't be here if I weren't absolutely stumped, but I'm hopeful that once again the experience and knowledge of the group shines bright. I thank you for taking the time to read this wall of text. The good intentions alone are appreciated, thanks for being the type of person that makes SO so useful to all!

  • C# HttpListener without using netsh to register a URI

    - by Chris T
    My application uses a small webserver to server up some files and have a web interface for administration remotely. Right now the user has to use netsh to register the URI like so netsh http add urlacl url=http://+:1233/ user=Chris-PC\Chris Which is no fun for the average user. I'd like the program to be able to listen on any port specified by the user from my program without the end-user needing to using command prompt. Is there anyway to accomplish this short of just using Process.Start and running command prompt myself?

I have the c source code for the target program I'm trying to manipulate, and I've gotten to the point where I can successfully overwrite the eip for the current function stack frame. However, I always get a Segmentation fault, because the address I supply is always wrong. The problem is that the current function is inside a pthread, and therefore, the address of the stack seems to always change between different runs of the program. Is there any method for finding the stack address within a pthread (or for estimating the stack address within a pthread)? (note: pthread_create's 2nd argument is null, so we're not manually assigning a stack address)

  • Win C#: Run app as administrator without UAC prompt

    - by paja
    Hello, I need one of my .exe to always run as administrator without UAC prompt. My program will be installed with setup, which will have for one time admin rights, and I need to perform such step in this setup that my exe will be always executed as admin without UAC prompt. I've found 2 solutions so far: 1) Use custom service, which will elevate the program for me. 2) Use tash scheduler: http://www.howtogeek.com/howto/windows-vista/create-administrator-mode-shortcuts-without-uac-prompts-in-windows-vista/ Is there any other solution? Some manifest probably? Thanks.

  • Variants recursively uses itself?

    - by Mason Wheeler
    I'm trying to build a debug version of rtl140.bpl to make debugging apps with runtime packages easier. I built the DPK and ran DCC32 on it, and it gets a ways in, then dies. C:\Program Files (x86)\Embarcadero\RAD Studio\7.0\source\Win32\rtl\sys\Variants.pas(1072) Fatal: F2092 Program or unit 'Variants' recursively uses itself But looking at Variants.pas, I can't see how. It only uses SysUtils and Types in the interface section, and neither of those use Variants, or use anything that uses Variants. Does anyone have any idea why this is breaking?

  • MinGW/G++/g95 link problem - libf95 undefined reference to `MAIN_'

    - by pivakaka
    Hi folks, Summing up, my problem consists on compiling g95 objects inside a C++ application. Actually, I'm constructing an interface for an old fortran program. For this task, I'm using the wxWidgets GUI library, and calling fortran subroutines when necessary. At the beginning, I was developing the entire project compiling my fortran files with gfortran (which comes with GCC) and linking them with my app by the g++ -o... command. Everything was working fine but some numbers values calculated by my fotran subroutines returned NAN values. Doing some research, I realized that compiling my fortran files with gfortran with the -m32 flag, generates this NAN values problem. Although compiling with -m64 flag, my code works properly well. The only trouble here is that my App should be 32bits and then I tryed another compiller. Here I found g95 Fortran compiler, which compiles my fortran code and gives the right output on a 32bits environment. But when I'm trying to link these g95 objects into my program I see this following error: g++ -oCyclonTechTower.exe src\fortran\Modulo_Global.o src\fortran\Prop_Fisicas.o src\fortran\inversa.o src\fortran\tower.o src\fortran\PredadeCarga.o src\fortran\gota.o src\fortran\tadi.o src\view\SimulationORSATCustomDialog.o src\view\SimulationChildGUIFrame.o src\view\ParentGUIFrame.o src\view\ClientGUIFrame.o src\model\TowerData.o src\controller\SimulationController.o src\THEIACyclonTechTower.o ..\Resource\resource.o -Lc:\wxWidgets-2.6.4\lib -Lc:\MinGW\lib\gcc-lib\i686-pc-mingw32\4.1.2 -Bdynamic -Wl,--subsystem,windows -mwindows c:\wxWidgets-2.6.4\lib\libwx_mswu-2.6.a -lwxregexu-2.6 -lwxexpat-2.6 -lwxtiff-2.6 -lwxjpeg-2.6 -lwxpng-2.6 -lwxzlib-2.6 -lrpcrt4 -loleaut32 -lole32 -luuid -lwinspool -lwinmm -lshell32 -lcomctl32 -lcomdlg32 -lctl3d32 -ladvapi32 -lwsock32 -lgdi32 -lgcc -lf95 c:\MinGW\lib\gcc-lib\i686-pc-mingw32\4.1.2/libf95.a(main.o):(.text+0x32): undefined reference to `MAIN_' collect2: ld returned 1 exit status Build error occurred, build is stopped Time consumed: 1531 ms. I have already read the g95 Manual for integration with C++ and I'm actually calling these functions bellow for controlling the fortran environment: void g95_runtime_start(int argc, char *argv[]); void g95_runtime_stop(); I also included the g95 Fortran Runtime Library libf95.a and the libgcc.a into my linker command. Finishing, I don't have a main method implemented because this is managed by wxWidgets, and my fortran subroutines can not have a main function because this is a C++ program calling fortran functions. Can some of you guys help me with this problem? How can I fix this undefined reference to MAIN__ problem? Any idea will be much appreciated. Thanks in advance, George

  • Segmented Control to change views

    - by Goods
    I have created an up/down arrow segmented control button on the right side of the navigation bar in my detail view. In a table based application, how can I use these up/down arrows to move through cells in the parent table? The apple "NavBar" sample code has an example of this but the controls are not functional. The iBird program has this functionality as well and it is very nice. Download the "iBird 15" program for free. Any thoughts? Thanks!

  • Dynamic programming - Coin change decision problem?

    - by Tony
    I'm reviewing some old notes from my algorithms course and the dynamic programming problems are seeming a bit tricky to me. I have a problem where we have an unlimited supply of coins, with some denominations x1, x2, ... xn and we want to make change for some value X. We are trying to design a dynamic program to decide whether change for X can be made or not (not minimizing the number of coins, or returning which coins, just true or false). I've done some thinking about this problem, and I can see a recursive method of doing this where it's something like... MakeChange(X, x[1..n this is the coins]) for (int i = 1; i < n; i++) { if ( (X - x[i] ==0) || MakeChange(X - x[i]) ) return true; } return false; Converting this a dynamic program is not coming so easily to me. How might I approach this?
