  • How to read a PS file in reverse order?

    - by Raja Reddy
    I have a PS file to be read in reverse order and process accordingly. Do we have a way to mention to read the file in reverse order in FD in COBOL module? OR do we have something to achieve the same using SORT? Note: Reading the records into a buffer (array) and using it in reverse order would be the first idea that comes to mind but that way doesnt work for file with millions of records. Your suggestions will be appreciated.

  • Fastest gap sequence for shell sort ?

    - by Tony
    According to Marcin Ciura's Optimal (best known) sequence of increments for shell sort algorithm. The best sequence for shellsort is 1, 4, 10, 23, 57, 132, 301, 701... But how can I generate such a sequence ? In Marcin Ciura's paper he said : Both Knuth’s and Hibbard’s sequences are relatively bad, because they are defined by simple linear recurrences but most algorithm books I searched , they all tend to use Knuth’s sequence : k = 3k + 1 ; because it's easy to generate , what's your way of generating shellsort sequence ?

  • How does cross domain authentication work in a firewalled environment?

    - by LVLAaron
    This is a simplification and the names have been changed to protect the innocent. The assets: Active Directory Domains corp.lan saas.lan User accounts [email protected] [email protected] Servers dc.corp.lan (domain controller) dc.saas.lan (domain controller) server.saas.lan A one way trust exists between the domains so user accounts in corp.lan and log into servers in saas.lan No firewall between dc.corp.lan and dc.saas.lan server.saas.lan is in a firewalled zone and a set of rules exist so it can talk to dc.saas.lan I can log into server.saas.lan with [email protected] - But I don't understand how it works. If I watch firewall logs, I see a bunch of login chatter between server.saas.lan and dc.saas.lan I also see a bunch of DROPPED chatter between server.saas.lan and dc.corp.lan. Presumably, this is because server.saas.lan is trying to authenticate [email protected] But no firewall rule exists that allows communication between these hosts. However, [email protected] can log in successfully to server.saas.lan - Once logged in, I can "echo %logonserver%" and get \dc.corp.lan. So.... I am a little confused how the account actually gets authenticated. Does dc.saas.lan eventually talk to dc.corp.lan after server.saas.lan can't talk to dc.corp.lan? Just trying to figure out what needs to be changed/fixed/altered.

  • Missing Home Folder XP Clients 2008R2 Domain

    - by minamhere
    We just completed a migration from Server 2003 to Server 2008R2. Everything seems to have gone well except that many of our desktops have stopped mapping the Home Folder as set in Active Directory. Other mappings that are defined on individual clients are mapping just fine, these mappings are all on the same file server as the failing Home Folders. Half of the users are on 1 file server and half are on another. Users from both servers are having this problem. I have enabled the Group Policy setting to "Wait for network before logging in". I enabled the policy to "Run Logon Scripts synchronously". There are no errors on the Domain Controller or either File Server. When I enabled Group Policy Preferences as an attempted workaround, I get this error: The user 'V:' preference item in the '<Policy Name>' Group Policy object did not apply because it failed with error code '0x800708ca This network connection does not exist.' This error was suppressed. This seems to indicate that the network connection is not ready by the time Group Policy is processed. But isn't this the point of the "Wait before logging in" and "Run Logon scripts synchronously" settings? Some other background facts: The new Server 2008R2 installation is a Virtual Machine. It is on a new Subnet in a different building from the old server. DNS and DHCP were also migrated from the old DC to this new DC. These Home Folders were all working properly before the migration. Are there new security restrictions/policies in Server 2008R2 that might be causing this? Is there a way to check whether I have an underlying network connectivity issue? Maybe moving the server to the new building is causing a delay/timeout? Any thoughts or ideas on what could be causing this or how I can resolve this? Thanks.

  • directory listing on Mac OS X

    - by user27150
    I dumped a bunch of files (music and otherwise) onto my shiny new Macbook, and since I'm more comfortable with linux than Mac (at this point) I tend to use the terminal. I did a ls -al on the files I'd transfered, and some had an "@" at the end of the permissions string, and some did not. Something like: drwxrwxr--@ 93 user staff etc. drwxrwxr-- 107 user staff etc. The ones without "@" could be seen in Finder and accessed by other programs-- the "@" files and directories were invisible. Can anyone explain what the "@" means, and how to chmod (or whatever) so I can use these files? I assume it is some sort of system flag but I don't know how to unset it. Chmod 777 had no effect and I already own the files. Thanks

  • How to sort a boxplot by the median values in pandas

    - by Chris
    I've got a dataframe outcome2 that I generate a grouped boxplot with in the following manner: In [11]: outcome2.boxplot(column='Hospital 30-Day Death (Mortality) Rates from Heart Attack',by='State') plt.ylabel('30 Day Death Rate') plt.title('30 Day Death Rate by State') Out [11]: What I'd like to do is sort the plot by the median for each state, instead of alphabetically. Not sure how to go about doing so.

  • Windows AD DNS: Event ID 5504

    - by Chris_K
    Two of my AD controllers (both running DNS service) appear to be having a similar issue. Both are throwing lots of events in the DNS events that look like this: Event Type: Information Event Source: DNS Event Category: None Event ID: 5504 Date: 5/24/2010 Time: 11:51:38 AM User: N/A Computer: ALPHA Description: The DNS server encountered an invalid domain name in a packet from 76.74.137.6. The packet will be rejected. The event data contains the DNS packet. That will come with the same event, same time, with a packet from 76.74.137.7 as well. I know this is "Information" not an error, but since it is new and different it bothers me (yes, I fear unexplained change!) Both machines are running Windows 2003 R2 SP2. The DNS servers are not exposed to the internet. Both DNS servers are configured to use OpenDNS for Forwarders. For both servers, this started about a week ago. Any thoughts on: 1) should I be concerned? 2) how can I stop/fix this? To keep it interesting, I have a 3rd AD / DNS box. Same domain, different Active Directory site. Same forwarders, yet doesn't have this issue.

  • Error 53 - The network path was not found.

    - by Jack
    I have a machine in my Active Directory Domain that I can no longer "net view" from other machines in the domain. This is a Windows XP Pro machine. It is hosting a VMWare virtual of my Domain Controller. If I attempt to net view [machine name] I get system error 53, The network path was not found. This is not a DNS issue, the same thing happens with the machine's IP. I don't think it's a firewall issue, I turned the firewall off on this machine. As I mentioned, it has worked in the past, and then stopped for no reason that I can see. I (intentionally) didn't change the software. I CAN get to the VMs hosted on this machine, can connect to their shares, net view them, etc. All other machines can see each other. In fact, the problem machine can see other machines and access their shares just fine. I tried removing the machine from the domain and re-adding it. I tried deleting the shares and recreating them. Not sure how to troubleshoot this any further. Any ideas?

  • Freebsd Secondary Group not allowing folder deletion

    - by Jarrod Juleff
    TLDR: I have a user that is a member to a group as a secondary group. This user can delete files with 664 perms as a secondary user, but not directories with perms of 775. Details: I have a user. Lets call him ftpuser. I use him to upload and download files to my devbox. The user's primary group is "ftp" and is also in the group "www" as a secondary group. My web server runs as user www and group www, and I have proftpd (running as www and www) configured to drop all files into the needed directories as www and www (for file ownership) and perms 664 on files and 775 on directories. My problem is (tried with 2 ftp clients) the ftp client can delete the files, but not the folders. Filezilla returns 550 permission denied. The owner only can delete flag is not set, and I've triple checked the permissions and they are indeed 775. Its driving me nuts to have to log into my server to manually delete folders every time. Some of the folders and files are created by 1 of my php scripts, but the permissions are getting set properly when I check the files' properties. Directory and file creation works phenomenal. Can delete files, just not directories. Freebsd 9.0 Running in VirtualBox (32bit all the way around) Proftpd (running as www and www) as ftp server (tried using both dreamweaver and filezilla as the clients) Basic amp setup (apache,mysql,and php).

  • combine two arrays and sort

    - by Jun
    Given two arrays like the following: a = array([1,2,4,5,6,8,9]) b = array([3,4,7,10]) I would like the output to be: c = array([1,2,3,4,5,6,7,8,9,10]) or: c = array([1,2,3,4,4,5,6,7,8,9,10]) I'm aware that I can do the following: c = sort(unique(concatenate((a,b))) I'm just wondering if there is a faster way to do it as the arrays I'm dealing with have millions of elements. Any idea is welcomed. Thanks

  • Group Policy installation failed error 1274

    - by David Thomas Garcia
    I'm trying to deploy an MSI via the Group Policy in Active Directory. But these are the errors I'm getting in the System event log after logging in: The assignment of application XStandard from policy install failed. The error was : %%1274 The removal of the assignment of application XStandard from policy install failed. The error was : %%2 Failed to apply changes to software installation settings. The installation of software deployed through Group Policy for this user has been delayed until the next logon because the changes must be applied before the user logon. The error was : %%1274 The Group Policy Client Side Extension Software Installation was unable to apply one or more settings because the changes must be processed before system startup or user logon. The system will wait for Group Policy processing to finish completely before the next startup or logon for this user, and this may result in slow startup and boot performance. When I reboot and log in again I simply get the same messages about needing to perform the update before the next logon. I'm on a Windows Vista 32-bit laptop. I'm rather new to deploying via group policy so what other information would be helpful in determining the issue? I tried a different MSI with the same results. I'm able to install the MSI using the command line and msiexec when logged into the computer, so I know the MSI is working ok at least.

  • DRUPAL: order exposed filter items, be carefully it is not that simple (I cannot user "Sort")

    - by Patrick
    hi, DRUPAL question. I'm using Views, with an exposed filter (Taxonomy). I've downloaded the "better exposed filter" module to display it as checkbox list. a Now, how can I order the tags in the filter list ? "Views Sort" is not the solution because I only can order articles but not the filter items!! I want to add an option (checkbox) for the customer to order the tags alphabetically or leave them in the default order. thanks

  • OSX Server 10.5 - Cannot log into Workgroup Manager - diradmin password is correct

    - by Mister IT Guru
    I've got a setup where I am trying to rescue a broken AD. We can no longer authenticate on the Workgroup manager, with passwords being rejected all the time - even though it is correct. I can connect using the workgroup manager on another server and I get the user list as expected, but when I click the padlock to make changes, I get the following screen: The problem is, I know the password is correct, I just used it to connect to the server in the first place. I can log into the server using the local admin, and services such as AFP, VPN and SMB continue to serve users. I have about 300 or so users on this server, and I would very much like to avoid having a rebuild. As there is much configuration that has been done without my knowledge (it's a client machine), I'd like to attempt to fix it, and then create another server and migration OD off this broken machine, then decommission it "gently". Ultimately this would mean no disruption of services. What I'd like it some tips as to how to fix the problem with authenticating to make changes in the work group manager, and maintenance on open directory in general. Thanks

  • Windows clients unable to access Samba share on AD joined Linux box every 7 days

    - by Hassle2
    The problem: Every 7 days, 2 Windows Servers are unable to access a SMB/CIFS share. It will start working after a handful of hours. The environment: OpenFiler Linux box joined to 2003 AD Domain Foreground app on Win2003 server access the SMB/CIFS share with windows credentials Another process on Win2008 access the share via SQL Server with windows credentials The Samba version on the Linux box is 3.4.5. Security is set to ADS wbinfo and getent return back expected users and groups Does not look to be a double hop issue as it's always the 2 accounts, regardless of the calling user. There is a DNS entry in both forward and reverse lookup zone for the linux box The linux box's computer object in active directory shows that it was modified around/at the same time that the two clients started failing to access the share Trying to access the share via IP works when by name does not Rebooting the Windows server takes care of it (it's production and only restarted it once) Restarting smbd, winbind, nmbd had no effect Error in samba log for the client in question: smbd/sesssetup.c:342(reply_spnego_kerberos) Failed to verify incoming ticket with error NT_STATUS_LOGON_FAILURE! The Question: Does this look like the machine account password is changing (hence the AD object showing the updated modified date) or are the two windows clients unable to request a new ticket that works against this linux box?

  • Single Sign On for intranet with Apache and Linux MIT Kerberos

    - by Beerdude26
    Greetings, I am looking for a way to do a single sign on to an intranet in the following manner: A Linux user logs on via a graphical frontend (for example, GNOME). He automatically requests a TGT for his username from the MIT Kerberos KDC. Via some way or another, the Apache server (which we'll assume is on the same server as the KDC), is informed that this user has logged in. When the user accesses the intranet, he is automatically granted access to his web applications. I don't think I've seen this kind of functionality while searching the net. I know the following possibilities exist: Using an authentication module such as mod_auth_kerb, a user is presented with a login prompt to enter his username and password, which are then authenticated against the MIT Kerberos server. (I would like this to be automatic.) IIS supports integrated Windows logon via ASP.Net when the user is part of an Active Directory. (I'm looking for the Linux / Apache equivalent.) Any suggestions, criticism and ideas are highly appreciated. This is for a school project to show a proof-of-concept, so every handy piece of information is more than welcome. :)

  • UITableView reloadData to sort the table cells

    - by harekam_taj
    Hey Guys, I have a uitableview and I am populating the tableview with data from the internet. I added some sort features to the table but when I do the sorting and get new results from the web server and reload the table. The table doesn't refresh, the old results stay on the table and if I press on a particular cell I see the new result just for that cell. Can someone please help me? Thanks

  • Silverlight DataGrid's sort by column doesn't update programmatically changed cells

    - by David Seiler
    For my first Silverlight app, I've written a program that sends user-supplied search strings to the Flickr REST API and displays the results in a DataGrid. Said grid is defined like so: <data:DataGrid x:Name="PhotoGrid" AutoGenerateColumns="False"> <data:DataGrid.Columns> <data:DataGridTextColumn Header="Photo Title" Binding="{Binding Title}" CanUserSort="True" CanUserReorder="True" CanUserResize="True" IsReadOnly="True" /> <data:DataGridTemplateColumn Header="Photo" SortMemberPath="ImageUrl"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" VerticalAlignment="Center"> <TextBlock Text="Click here to show image" MouseLeftButtonUp="ShowPhoto"/> <Image Visibility="Collapsed" MouseLeftButtonUp="HidePhoto"/> </StackPanel> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> </data:DataGridTemplateColumn> </data:DataGrid.Columns> </data:DataGrid> It's a simple two-column table. The first column contains the title of the photo, while the second contains the text 'Click here to show image'. Clicks there call ShowPhoto(), which updates the Image element's Source property with a BitmapImage derived from the URI of the Flickr photo, and sets the image's visibility to Visible. Clicking on the image thus revealed hides it again. All of this was easy to implement and works perfectly. But whenever I click on one of the column headers to sort by that column, the cells that I've updated in this way do not change. The rest of the DataGrid is resorted and updated appropriately, but those cells remain behind, detached from the rest of their row. This is very strange, and not at all what I want. What am I doing wrong? Should I be freshening the DataGrid somehow in response to the sort event, and if so how? Or if I'm not supposed to be messing with the contents of the grid directly, what's the right way to get the behavior I want?

  • How to build, sort and print a tree of a sort?

    - by Tuplanolla
    This is more of an algorithmic dilemma than a language-specific problem, but since I'm currently using Ruby I'll tag this as such. I've already spent over 20 hours on this and I would've never believed it if someone told me writing a LaTeX parser was a walk in the park in comparison. I have a loop to read hierarchies (that are prefixed with \m) from different files art.tex: \m{Art} graphical.tex: \m{Art}{Graphical} me.tex: \m{About}{Me} music.tex: \m{Art}{Music} notes.tex: \m{Art}{Music}{Sheet Music} site.tex: \m{About}{Site} something.tex: \m{Something} whatever.tex: \m{Something}{That}{Does Not}{Matter} and I need to sort them alphabetically and print them out as a tree About Me (me.tex) Site (site.tex) Art (art.tex) Graphical (graphical.tex) Music (music.tex) Sheet Music (notes.tex) Something (something.tex) That Does Not Matter (whatever.tex) in (X)HTML <ul> <li>About</li> <ul> <li><a href="me.tex">Me</a></li> <li><a href="site.tex">Site</a></li> </ul> <li><a href="art.tex">Art</a></li> <ul> <li><a href="graphical.tex">Graphical</a></li> <li><a href="music.tex">Music</a></li> <ul> <li><a href="notes.tex">Sheet Music</a></li> </ul> </ul> <li><a href="something.tex">Something</a></li> <ul> <li>That</li> <ul> <li>Doesn't</li> <ul> <li><a href="whatever.tex">Matter</a></li> </ul> </ul> </ul> </ul> using Ruby without Rails, which means that at least Array.sort and Dir.glob are available. All of my attempts were formed like this (as this part should work just fine). def fss_brace_array(ss_input)#a concise version of another function; converts {1}{2}...{n} into an array [1, 2, ..., n] or returns an empty array ss_output = ss_input[1].scan(%r{\{(.*?)\}}) rescue ss_output = [] ensure return ss_output end #define tree s_handle = File.join(:content.to_s, "*") Dir.glob("#{s_handle}.tex").each do |s_handle| File.open(s_handle, "r") do |f_handle| while s_line = f_handle.gets if s_all = s_line.match(%r{\\m\{(\{.*?\})+\}}) s_all = s_all.to_a #do something with tree, fss_brace_array(s_all) and s_handle break end end end end #do something else with tree

  • tableSorter limitation (sort) one page at a time?

    - by Abu Hamzah
    i see that in tableSorter you can sort one page at a time which concerns me. Only 1 page of results can be sorted at a time?, which is pretty limiting. If you have a query result that spans multiple pages, how you will handle this? If anyone knows better, feel free to correct me if iam incorrect Thanks.

  • Where does Tomcat append / to directory paths?

    - by Anonymouse
    Suppose my Tomcat webapps directory looks like this: webapps/ webapps/fooapp/ webapps/fooapp/WEB-INF/ webapps/fooapp/WEB-INF/web.xml webapps/fooapp/bardir/ When I make a GET request for /fooapp/bardir, Tomcat sees that webapps/fooapp/bardir is a directory and sends back a 302 to /fooapp/bardir/ (with a slash at the end). Here is my question: Where in the Tomcat source code does this take place? (I'm looking at 6.0.x but a correct answer for any version would be a great starting point.) The only reference material I can find on this subject is in the Catalina Functional Specifications which states, regarding the Default Servlet: On each HTTP GET request processed by this servlet, the following processing shall be performed: [...] If the requested resource is a directory: If the request path does not end with "/", redirect to a corresponding path with "/" appended so that relative references in welcome files are resolved correctly. However, this functionality does not appear to be in org.apache.catalina.servlets.DefaultServlet; or at least, it's not there exclusively: if I replace the default servlet in web.xml with a servlet whose servlet-class does not exist, directory paths still come back 302 to add the slash, while every other request comes back with an error as expected.

  • SBS 2011 Essentials and too many new Mac users

    - by Harry Muscle
    We currently have about 15 users on a Windows SBS 2011 Essentials Server. I've just been informed that we plan to bring aboard about 15 more users that will be using Macs. We'll be using a Mac Server to manage the 15 new Macs, however, I'm looking for advice on how to best set this all up. Ideally I would just add the 15 new Mac users to Active Directory and setup the Mac Server to authenticate against AD, unfortunately the SBS 2011 Essentials Server has a limit of 25 users, so adding these new users to AD won't work unless we upgrade the Windows server (which I'd rather avoid since it's a lot of work and a lot of money). That leaves the option of creating user accounts for these 15 Mac users on the Mac Server only. The problem that this creates though is how do I share files been Mac users and Windows users since they are now using different systems for network authentication. Any advice (short of upgrade to SBS Standard) is highly appreciated. Thanks, Harry P.S. We don't run Exchange or anything else on our server ... it's mainly used for file sharing and enforcing security via group policies.
