• Looking for a powershell script that can pull a file from a set of PC's and FTP

  - by DangeRuss

  I'm looking to write a script (preferably powershell) that will essentially copy a file from a bunch of PC's and FTP it to a server. So the structure of the environment is that we have a file on multiple PC's (around 50 or so) that need to placed on a server. Sometimes one of the PC's may be turned off so the script would first need to ensure the PC is up and running (maybe a ping result), then it would need to go into a directory on that PC, pull a file off of it, rename the file, place into a source directory, then remove the file. Naming convention doesn't matter, but date/time stamp would be easiest. Ideally, it would be best to first move all the files to a source directory to save on FTP bandwidth, but since the files will be named the same, the files must be renamed during the move process. Move not copy because the directory needs to be empty so the file can be re-created the next day. So once moved to the source directory, now all the files need to be FTP'd to a server for processing. After all of this, we need to know which PC's on the list did not respond so we can manually retrieve the file so the script should output a file (txt is fine) that will show which PC's were offline. Everything is one domain and script will be run from an server with admin creds. Thank you!

• How to quickly remove hundreds of thousands of files? [closed]

  - by Nick

  Possible Duplicate: Doing an rm -rf on a massive directory tree takes hours I'm running a simulation program on a computing cluster (Scientific Linux) that generates hundreds of thousands of atomic coordinate files. But I'm having a problem deleting the files because rm -rf never completes and neither does find . -name * | xargs r Isn't there a way to just unlink this directory from the directory tree? The storage unit is used by hundreds of other people, so reformatting is not an option. Thanks

• Linux SFTP and many local user accounts, limits with mount --bind?

  - by user123428

  I am in the process of building a solution to handle many developers (possibly hundreds) to work on their files via sftp, each one Jailed in their home directory. For our particular needs, we have a samba mount point that contains all of the users home directories. I have started developing the following solution and hit some walls: - I have configured a Ubuntu Lucid Server as sftp server. - In order to jail the user in their home directory (without allowing them the browse a directory up and seeing all the other users folders) I am using mount --bind and not a symbolic link (also some ftp clients don't really work with sym links). - The user accounts are local unix user accounts on the sftp server (not using a directory service or anything) that have an empty home folder created on the local machine, then I use mount --bind to bind the empty folder to the actual users home directory on the samba share. With this solution I am hitting a couple of problems, in the case of a server reboot, all the mount --binds are lost because they are not written in fstab. Then I have read somewhere that the maximum amount of entries in fstab are 400 (which does not really help us). I have thought of a solution of writing something that stores the mounts in a text file as a backup and on server reboot, run the script that re mounts. I am just really unsure about this whole process and was wondering if anyone has any insight on possibly a better solution for SFTP? (not FTP)

• How can I tell when an FTP is complete?

  - by identry

  I have a cron job that processes files that my client's upload via FTP to my FreeBSD server. The cron job runs once an hour, and normally processing each file only takes a few seconds. The cron job looks in the client's upload directory and moves any new files to a tmp directory. It then processes the file(s) and moves them into a final directory where they are then available to the public through a website. The problem is, every once in awhile, the cron job runs just as a new file is being uploaded. It moves the half-uploaded file to the tmp directory, and tries to process it, and fails, of course. Question: how can I determine if the uploaded file is complete? The only thing I can think of is checking the file size to see if it's changing, but that seems like a kludge. Is there some sort of flag or something that is set when the upload is complete?

• Web service using Data Dynamics ActiveReports occasionally slows down

  - by Swoop

  My company is running into a problem with a web service that is written in C#/ASP.Net. The service receives an identity key for data in SQL Server and a path to generate and save a PDF report for this data. In most cases, this web service returns results to the calling web pages very quickly, usually within a few seconds max. However, it seems to occasionally hit a significant slowdown. The web application calling the web service will generate a timeout error when this slowdown occurs. We have checked and the PDF does get created and saved to the server, so it looks like the web service eventually finishes executing. It seems to take about 1 to 2 minutes for processing to have completed. The PDF is generated using ActiveReports from Data Dynamics. Wwhen this problem occurs, making a small change to the web service's config file (ie, adding a blank space to a connection string line) seems to restart the web service and everything is perfectly ok for a period of time afterwards. Other web applications that are running on the same web server do not seem to experience this type of behavior, only this particular web service. I have added the code for the web service below. It is basic calls to 3rd party libraries. We are not able to recreate this problem in test. I am wondering what might be causing this issue? [WebMethod] public string Publish(int identity, string transactionType, string directory, string filename) { try { AdpConnection Conn = new AdpConnection(ConfigurationManager.AppSettings["myDBConnString"]); AdpCommand Cmd = new AdpCommand("storedproc_GetData", oConn); AdpParameter Param; Cmd.CommandType = CommandType.StoredProcedure; Param = Cmd.CreateParameter("@Identity", DbType.Int32); Param.Value = identity; Cmd.Parameters.Add(oParam); Conn.Open(); string aResponse = Cmd.ExecuteScalar().ToString(); Conn.Close(); if (transactionType == "typeA") { //Parse response DataSet dsResponse = ParseDataResponse(aResponse); //dsResponse.WriteXml(@ConfigurationManager.AppSettings["DocsDir"] + identity.ToString() + ".xml"); DataDynamics.ActiveReports.ActiveReport3 rpt = new DataDynamics.ActiveReports.ActiveReport3(); rpt.LoadLayout(@ConfigurationManager.AppSettings["myReportPath"] + "TypeA.rpx"); rpt.AddNamedItem("ReportPath", @ConfigurationManager.AppSettings["myReportPath"]); rpt.AddNamedItem("XMLSTRING", FormatXML(dsResponse.GetXml())); DataDynamics.ActiveReports.DataSources.XMLDataSource xmlds = new DataDynamics.ActiveReports.DataSources.XMLDataSource(); xmlds.FileURL = null; xmlds.RecordsetPattern = "//DataPatternA"; xmlds.LoadXML(FormatXML(dsResponse.GetXml())); if (!System.IO.Directory.Exists(@ConfigurationManager.AppSettings["DocsDir"] + directory + @"\")) { System.IO.Directory.CreateDirectory(@ConfigurationManager.AppSettings["DocsDir"] + directory + @"\"); } string sXML = FormatXML(dsResponse.GetXml()); StreamWriter sw = new StreamWriter(@ConfigurationManager.AppSettings["DocsDir"] + directory + @"\" + filename + ".xml", false); sw.Write(sXML); sw.Close(); rpt.DataSource = xmlds; rpt.Run(true); DataDynamics.ActiveReports.Export.Pdf.PdfExport xPdf = new DataDynamics.ActiveReports.Export.Pdf.PdfExport(); xPdf.Export(rpt.Document, @ConfigurationManager.AppSettings["DocsDir"] + directory + @"\" + filename + ".pdf"); } } catch(Exception ex) { return "Error: " + ex.ToString(); } return @ConfigurationManager.AppSettings["DocsDir"] + directory + @"\" + filename + ".pdf"; }

• File Fix-it codegolf (GCJ 2010 1B-A)

  - by KirarinSnow

  Last year (2009), the Google Code Jam featured an interesting problem as the first problem in Round 1B: Decision Tree As the problem seemed tailored for Lisp-like languages, we spontaneously had an exciting codegolf here on SO, in which a few languages managed to solve the problem in fewer characters than any Lisp variety, using quite a number of different techniques. This year's Round 1B Problem A (File Fix-it) also seems tailored for a particular family of languages, Unix shell scripts. So continuing the "1B-A tradition" would be appropriate. :p But which language will end up with the shortest code? Let us codegolf and see! Problem description (adapted from official page): You are given T test cases. Each test case contains N lines that list the full path of all directories currently existing on your computer. For example: /home/awesome /home/awesome/wheeeeeee /home/awesome/wheeeeeee/codegolfrocks /home/thecakeisalie Next, you are given M lines that list the full path of directories you would like to create. They are in the same format as the previous examples. You can create a directory using the mkdir command, but you can only do so if the parent directory already exists. For example, to create the directories /pyonpyon/fumufumu/yeahyeah and /pyonpyon/fumufumu/yeahyeahyeah, you would need to use mkdir four times: mkdir /pyonpyon mkdir /pyonpyon/fumufumu mkdir /pyonpyon/fumufumu/yeahyeah mkdir /pyonpyon/fumufumu/yeahyeahyeah For each test case, return the number of times you have to call mkdir to create all the directories you would like to create. Input Input consists of a text file whose first line contains the integer T, the number of test cases. The rest of the file contains the test cases. Each test case begins with a line containing the integers N and M, separated by a space. The next N lines contain the path of each directory currently existing on your computer (not including the root directory /). This is a concatenation of one or more non-empty lowercase alphanumeric strings, each preceded by a single /. The following M lines contain the path of each directory you would like to create. Output For each case, print one line containing Case #X: Y, where X is the case number and Y is the solution. Limits 1 = T = 100. 0 = N = 100. 1 = M = 100. Each path contains at most 100 characters. Every path appears only once in the list of directories already on your computer, or in the list of desired directories. However, a path may appear on both lists, as in example case #3 below. If a directory is in the list of directories already on your computer, its parent directory will also be listed, with the exception of the root directory /. The input file is at most 100,000 bytes long. Example Larger sample test cases may be downloaded here. Input: 3 0 2 /home/sparkle/pyon /home/sparkle/cakes 1 3 /z /z/y /z/x /y/y 2 1 /moo /moo/wheeeee /moo Output: Case #1: 4 Case #2: 4 Case #3: 0 Code Golf Please post your shortest code in any language that solves this problem. Input and output may be handled via stdin and stdout or by other files of your choice. Please include a disclaimer if your code has the potential to modify or delete existing files when executed. Winner will be the shortest solution (by byte count) in a language with an implementation existing prior to the start of Round 1B 2010.

• maven test cannot load cross-module resources/properties ?

  - by smallufo

  I have a maven mantained project with some modules . One module contains one XML file and one parsing class. Second module depends on the first module. There is a class that calls the parsing class in the first module , but maven seems cannot test the class in the second module. Maven test reports : java.lang.NullPointerException at java.util.Properties.loadFromXML(Properties.java:851) at foo.firstModule.Parser.<init>(Parser.java:92) at foo.secondModule.Program.<init>(Program.java:84) In "Parser.java" (in the first module) , it uses Properties and InputStream to read/parse an XML file : InputStream xmlStream = getClass().getResourceAsStream("Data.xml"); Properties properties = new Properties(); properties.loadFromXML(xmlStream); The "data.xml" is located in first module's resources/foo/firstModule directory , and it tests OK in the first module. It seems when testing the second module , maven cannot correctly load the Data.xml in the first module . I thought I can solve the problem by using maven-dependency-plugin:unpack to solve it . In the second module's POM file , I add these snippets : <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>2.1</version> <executions> <execution> <id>data-copying</id> <phase>test-compile</phase> <goals> <goal>unpack</goal> </goals> <configuration> <artifactItems> <artifactItem> <groupId>foo</groupId> <artifactId>firstModule</artifactId> <type>jar</type> <includes>foo/firstModule/Data.xml</includes> <outputDirectory>${project.build.directory}/classes</outputDirectory> </artifactItem> </artifactItems> </configuration> </execution> </executions> </plugin> In this POM file , I try to unpack the first module , and copy the Data.xml to classes/foo/firstModule/ directory , and then run tests. And indeed , it is copied to the right directory , I can find the "Data.xml" file in "target/classes/foo/firstModule" directory. But maven test still complains it cannot read the File (Properties.loadFromXML() throws NPE). I don't know how to solve this problem. I tried other output directory , such as ${project.build.directory}/resources , and ${project.build.directory}/test-classes , but all in vain... Any advices now ? Thanks in advanced. Environments : Maven 2.2.1 , eclipse , m2eclipse

• Changing JButton background colour temporarily?

  - by sashep

  Hi, I'm super new to Java, and in need of some help. I'm making a little java desktop application where I basically have a grid of 4 JButtons ( 2 x 2 grid), and I need the background colour of individual JButtons to change, and after one second, change back to the original colour (the game I'm trying to make is like Simon, where you have to follow a pattern of buttons that light up). I have a vector that contains randomly generated numbers in the range of 1 to 4, and I want to be able to get each element from the vector and get the corresponding button to change to a different colour for one second (for example, if the vector contains 2 4 1, I would want button 2 to change, then button 4 to change, then button 1 to change). Is this possible or is there a better way to go about doing this with something other than JButtons? How do I implement this? Also, I'm running Mac OS X, which apparently (based on some things I've read on forums) doesn't like JButtons background changing (I think it's because of system look and feel), how can I change this so it works on mac? Thank you in advance for any help :)

• Question about the benefit of using an ORM

  - by johnny

  I want to use an ORM for learning purposes and am try nhibernate. I am using the tutorial and then I have a real project. I can go the "old way" or use an ORM. I'm not sure I totally understand the benefit. On the one hand I can create my abstractions in code such that I can change my databases and be database independent. On the other it seems that if I actually change the database columns I have to change all my code. Why wouldn't I have my application without the ORM, change my database and change my code, instead of changing my database, orm, and code? Is it that they database structure doesn't change that much? I believe there are real benefits because ORMs are used by so many. I'm just not sure I get it yet. Thank you. EDIT: In the tutorial they have many files that are used to make the ORM work http://www.hibernate.org/362.html In the event of an application change, it seems like a lot of extra work just to say that I have "proper" abstraction layers. Because I'm new at it it doesn't look that easy to maintain and again seems like extra work, not less.

• No GLX on Intel card with multiseat with additional nVidia card

  - by MeanEYE

  I have multiseat configured and my Xorg has 2 server layouts. One is for nVidia card and other is for Intel card. They both work, but display server assigned to Intel card doesn't have hardware acceleration since DRI and GLX module being used is from nVidia driver. So my question is, can I configure layouts somehow to use right DRI and GLX with each card?

• Unable to boot Ubuntu 13.10 (nVidia GTX 770m and Intel HD 4600)

  - by Raziel Gonzalez

  Ever since I bought this laptop I've been trying to install Ubuntu on it. It came with W8 preinstalled. Up to this point, I've been able to boot in UEFI mode with a black screen. I can tell it's trying to use the nVidia card (there's a led on the computer, depending on the color you can tell which GPU is using) and if I press crtl+alt+F1 I can go to console mode. Taking this advantage I tried to install bumblebee and after a successful install the led that indicates which GPU is being used change, indicating that it switched to the Intel HD 4600 graphics. After the installation I tried to initiate the graphic interface (startx) with no success.

• GNU screen, how to get current sessionname programmably

  - by Jimm Chen

  [ This can be considered step 2 of my previous question Is it possible to change GNU screen session name after created? ] Actually, I'd like to write a script that can display current screen session name and change current session name. For example: sren armcross It will change the session name to armcross (ARM gcc cross compiler) and output something like: screen session name changed from '25278.pts-15.linux-ic37' to 'armcross' So, the key question now is how to get current session name. Not only for display the old session name, but according to Is it possible to change GNU screen session name after created? , I have to know it(pass to -d -r) before I can change it to something else. Can we use $STY for current session name? No. $STY will not change after you have changed the session name to a user-defined one. However, for command screen -d -r <oldsessname> -X sessionname armcross should be the user-defined name(if ever defined) instead of $STY, otherwise, screen spouts error "No screen session found." Maybe, there is a verbose way, use screen -list to list all sessions(user-defined name listed), then, match the pid part from $STY against those listed sessions and we will find current session's user-defined name. It should not be so verbose for such a straightforward question. Don't you think so? The -d -D and -r -R options seems to expose too much implementation detail to screen's user. It seems, to rename a session, you have to detach it, then do the rename, then reattach it. Right? My env: opensuse 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06 Thank you.

• Dell PERC 5 - RAID-10 keeps rebuilding drive 2 every day

  - by raid question

  I have a Dell PowerEdge 2950 with this card: RAID bus controller [0104]: Dell PowerEdge Expandable RAID controller 5 [1028:0015] and six disks in a RAID-10. I replaced drive 2, because it didn't show up, and then it started to rebuild itself: root@backup01:~# megaraidsas-status -- Arrays informations -- -- ID | Type | Size | Status a0d0 | RAID 10 | 5587GiB | DEGRADED -- Disks informations -- ID | Model | Status | Warnings a0e8s0 | ATA ST2000DM001-9YN1 1863GiB | online | errs: media:0 other:5393 a0e8s1 | ATA ST2000DM001-9YN1 1863GiB | online | errs: media:0 other:5394 a0e8s2 | ATA ST2000DM001-1E61 1863GiB | rebuild | errs: media:0 other:99 a0e8s3 | ATA ST2000DM001-9YN1 1863GiB | online | errs: media:0 other:5393 a0e8s4 | ATA ST2000DM001-9YN1 1863GiB | online | errs: media:0 other:5393 a0e8s5 | ATA ST2000DM001-9YN1 1863GiB | online | errs: media:0 other:5393 The rebuild finishes, then the virtual drive becomes optimal, and drive 2 goes online. Then once a day, drive 2 acts like it's been removed, and the rebuild starts all over again. How do I make this once a day rebuild stop?

• Ubuntu 10.04 RGBA(Transparent theme) bug

  - by Nrew

  I tried to follow this tutorial frome ghacks.net. But I end up with a bug. Everytime I try to change the desktop background or the theme. It opens up lots of folders. And then close it back again. So I cannot do anything when I try to change the background or the theme to the default. Here is the tutorial And I can't even shutdown my machine now, please help. EDIT I tried executing these commands in the terminal sudo add-apt-repository ppa:erik-b-andersen/rgba-gtk sudo apt-get update && sudo apt-get upgrade sudo apt-get install gnome-color-chooser gtk2-module-rgba sudo apt-get install murrine-themes And it installed gnome color changer. It works, and the windows became transparent, but I can't change to the default theme and I can't put a background Here's the screenshot, when I try to change something in the preferences: Its just okay if I can't change the theme, but it won't let me change the background either. Or maybe the background is changed but its transparent just like the other windows. You can see that in the taskbar(or whatever its called in Ubuntu). Its full. What can I do to atleast make the background visible.

• Where is my problem? The P6X58D Premium Mobo, Windows 7, or other?

  - by Dylan Yaga

  I was having problems with my USB devices for an hour last night, and I am unable to determine the root cause of the problem. The two symptoms are: At seemingly random times (not consistently spaced by time or caused by any detectable event) my USB devices become "detached". Windows will play the USB disconnect sound and then the reconnect sound. The devices disconnected and then reconnected. My USB Keyboard will "stick" on one key for several seconds before processing any other keystroke made. The mouse also does not respond to clicks. I do not lose mouse movement or USB device connectivity. And after a moment of this several beeps will be emitted from the speakers. Hardware Specs: GFX Card: EVGA GeForce GTX 470 Superclocked 1280MB DDR5 PCIe Motherboard: ASUS P6X58D Premium Intel X58 Socket LGA1366 MB Processor: Intel Core i7-920 2.66Ghz 8M LGA1366 CPU Memory: Corsair Dominator 6144MB PC12800 DDR3 Storage: Hitachi 1TB Serial ATA HD 1600MHz 7200/32MB/SATA-3G Cooling: Corsair Hydro H50 CPU Liquid Cooler Case: Corsair Obsidian 800D Full Tower Case Power Supply: Corsair HX1000W 1000W Modular Power Supply Steps I have taken to narrow down the problem: Restarted the computer. - No change Changed USB port the Hub was connected to on the CPU. - No change Removed all devices from USB Hub and connected directly to CPU. - No change Used a different USB keyboard both in USB Hub and directly to CPU. - No change Disconnected and reconnected all cables. - No change Disassembled the Tower and determined if the USB headers were firmly connected. - No change Checked device manager for errors. Checked all USB devices. - Nothing flagged After an hour of frustration trying to narrow down the problem it appeared to disappear. But I am torn between it being a Mobo problem or an OS problem. Is there anything else I can do to narrow down the problem before a reformat and then eventually exchanging the Mobo?

• GNU screen, how to get current sessionname programmatically

  - by Jimm Chen

  [ This can be considered step 2 of my previous question Is it possible to change GNU screen session name after created? ] Actually, I'd like to write a script that can display current screen session name and change current session name. For example: sren armcross It will change the session name to armcross (ARM gcc cross compiler) and output something like: screen session name changed from '25278.pts-15.linux-ic37' to 'armcross' So, the key question now is how to get current session name. Not only for display the old session name, but according to Is it possible to change GNU screen session name after created? , I have to know it(pass to -d -r) before I can change it to something else. Can we use $STY for current session name? No. $STY will not change after you have changed the session name to a user-defined one. However, for command screen -d -r <oldsessname> -X sessionname armcross should be the user-defined name(if ever defined) instead of $STY, otherwise, screen spouts error "No screen session found." Maybe, there is a verbose way, use screen -list to list all sessions(user-defined name listed), then, match the pid part from $STY against those listed sessions and we will find current session's user-defined name. It should not be so verbose for such a straightforward question. Don't you think so? The -d -D and -r -R options seems to expose too much implementation detail to screen's user. It seems, to rename a session, you have to detach it, then do the rename, then reattach it. Right? My env: opensuse 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06 Thank you.

• Missing ODBCConfig for SQLite and LibreOffice Base

  - by MikeD

  I have used OpenOffice Base as a front end for SQlite databases, in 10.04 linked via ODBC. I am updating to 12.04, so I loaded LibreOffice Base, looks just like OObase. I have 12.04 on one drive and 10.04 on another. I loaded Sqliteman, sqlite3, unixodbc-bin, unixodbc, libsqliteodbc, sqlitebrowser. I copied my databases directory over. But in terminal ODBCConfig is not on the 12.04 system. So I copied odbc.ini from the home directory on 10.04 to 12.04 home directory, and now LibreOffice Base can access my database, and all is fine. Anyone know what is the problem with ODBCConfig, is it another victim of the change in QT? Of course I could edit odbc.ini with jedit, now I can see the format. In terminal I tried sudo find / -name ODBCConfig, but its not there.
