  • List of values as keys for a Map

    - by thr
    I have lists of variable length where each item can be one of four unique, that I need to use as keys for another object in a map. Assume that each value can be either 0, 1, 2 or 3 (it's not integer in my real code, but a lot easier to explain this way) so a few examples of key lists could be: [1, 0, 2, 3] [3, 2, 1] [1, 0, 0, 1, 1, 3] [2, 3, 1, 1, 2] [1, 2] So, to re-iterate: each item in the list can be either 0, 1, 2 or 3 and there can be any number of items in a list. My first approach was to try to hash the contents of the array, using the built in GetHashCode() in .NET to combine the hash of each element. But since this would return an int I would have to deal with collisions manually (two equal int values are identical to a Dictionary). So my second approach was to use a quad tree, breaking down each item in the list into a Node that has four pointers (one for each possible value) to the next four possible values (with the root node representing [], an empty list), inserting [1, 0, 2] => Foo, [1, 3] => Bar and [1, 0] => Baz into this tree would look like this: Grey nodes nodes being unused pointers/nodes. Though I worry about the performance of this setup, but there will be no need to deal with hash collisions and the tree won't become to deep (there will mostly be lists with 2-6 items stored, rarely over 6). Is there some other magic way to store items with lists of values as keys that I have missed?

  • Validating SSL clients using a list of authorised certificates instead of a Certificate Authority

    - by Gavin Brown
    Is it possible to configure Apache (or any other SSL-aware server) to only accept connections from clients presenting a certificate from a pre-defined list? These certificates may be signed by any CA (and may be self-signed). A while back I tried to get client certificate validation working in the EPP system of the domain registry I work for. The EPP protocol spec mandates use of "mutual strong client-server authentication". In practice, this means that both the client and the server must validate the certificate of the other peer in the session. We created a private certificate authority and asked registrars to submit CSRs, which we then signed. This seemed to us to be the simplest solution, but many of our registrars objected: they were used to obtaining a client certificate from a CA, and submitting that certificate to the registry. So we had to scrap the system. I have been trying to find a way of implementing this system in our server, which is based on the mod_epp module for Apache.

  • Using an allowed user list with VSFTPD

    - by Naftuli Tzvi Kay
    According to the Wiki here, you can only allow certain users to log in over FTP using the following configuration in your /etc/vsftp.conf file: userlist_enable=YES userlist_file=/etc/vsftp.user_list userlist_deny=NO I've configured my system to use this configuration, and I only have one user which I'd like to expose over FTP named streams, so my /etc/vsftp.user_list looks like this: streams Interestingly enough, I cannot log in once I enable to user list. If I change userlist_enable to NO, then things work properly, but if I enable it, I can't log in all, it just keeps trying to reconnect. I don't get a login failed message, it just keeps trying to reconnect when using lftp. My /etc/vsftp.conf file is available on Pastebin here and my /etc/vsftp.user_list is available here. What am I doing wrong here? I'd just like to only make the streams user able to log in.

  • List all devices of system

    - by pareshverma91
    In my understanding linux can list only those devices which it can understand, i.e. for which the drivers have been installed. I think lspci is the command for that. But how can one figure out if there exists some device in the system for which the drivers are not installed and perhaps some hint about what that device is for and what driver would suffice for it. I would like to know this info so as to be able to recompile my linux kernel to a minimum and would like to avoid a hit and trial approach.

  • .NET Mailserver smtp/relay problem

    - by Quandary
    Question, I'm trying to setup my own mailserver: This is the server (latest version): http://www.codeproject.com/KB/vista/SMTP_POP3_IMAP_server.aspx Now I've the following problem: I can add user accounts, and receive mails from the internet in that account. I can also setup a mailinglist. This works fine (for local users). But I can't send any emails out... Why ? I've forwarded port 25 + 110, and it works fine for receiving mails from the internet. Do I need to configure SMTP under SMTP, or under relay, or both ? Or do I miss anything ?

  • Windows XP does not list WPA wireless networks

    - by Tomalak
    What can be the reason that Windows XP does not show WPA-encrypted wireless networks? The laptop I have problems with is an older model (Toshiba Satellite Pro 6100) with Windows XP SP3 on it, fresh install. The wireless network card in it is an Agere product that lists as "Toshiba Wireless LAN Mini PCI Card". The networks showed up perfectly before I first tried to connect to one (it was set to WPA2). The connection failed (the card supports WPA only), then something must have happend and Windows hides these networks now. A manually configured WPA setup via Windows' own wizard works, I'm using it right now. The network just won't show up in the list of available network on its own. I suspect that XP incorrectly set a flag somewhere that this network card does not support WPA. Is there such a flag, and if so, how can I change it back?

  • Microsoft FTP fails to connect after the client requests the list of features (FEAT)

    - by Max
    This is a really weird problem. The first few times I try to connect Filezilla just hangs on the line 211-Extended features supported: for a while before coming up and saying Error: Could not connect to server. The filezilla log below: Command: PASS *********** Response: 230 User logged in. Command: FEAT Response: 211-Extended features supported: Error: Could not connect to server The weird thing is if I keep trying to connect eventually it just works and connects fine. After Filezilla knows which features the server supports it stops asking for a while which enables you to connect first time until Filezilla decides it wants to double check the features list again. I'm at a loss on how to debug this. Has anyone experienced similar?

  • I need access control within the same network/VLAN

    - by Sadiq ali
    Hi, I have a single network/VLAN and I want to block some traffic and allow some traffic in my network, is this possible using a L2 or L3 switch? If so which switches support this feature and what would be the commands to configure this? I have already tried this using access lists by applying it to an ethernet port but if I apply it on one port it will automatically work on incoming traffic on that port but I mean it to work on only outgoing traffic as per my ACL. Do you have any suggestions please?

  • Use Web Browser (Google Chrome or Firefox) to Open Web Sites from a List in File

    - by MMA
    I have a (text) file containing a list of web site addresses. I know that I can open the file in an editor and then copy-paste the addresses to the browser address bar. That means, if I have ten addresses in that file, I will need ten copy-paste operations, which must be tedious. But is there a way to ask the browser (preferably Google Chrome or Firefox) to open all of them in one go in different tabs? I am using Ubuntu, if that is related in any way to the solution you provide.

  • Access Denied on a Drive where All Users list have been deleted in Security Tab

    - by darkstar13
    Hi All, (System is Windows 7 x64) I wanted to restrict access of other people in a certain drive of my computer (Harddisk 1 is partitioned to C & D; I want to restrict Drive D). What I did was go to the Security Tab (under Drive Properties) and remove the All Users entry. My account is an administrator account. I left only Systems and Administrator on the list. However, when I tried to access drive D, I got an Access Denied error, and Security Tab is already missing. I tried to edit Local Group Policy; it does not work. Take Ownership is not available for the Drive as well, but I see it enabled if I select files / folders. Please help. Thanks. Also, I am wondering why, as an Administrator, have my access to that drive denied.

  • Pictures clicked on Start Menu's Recent Items list opens in non default program

    - by jay
    I am using Picasa Photo Viewer and have associated all JPG and PNG files to open with it. However when I open an image from the Recent Items list in the Windows 7 Start Menu it opens with Windows Photo Viewer. The context menu for such items reveals no actions that would make it go to Windows Photo Viewer, and the default (one in bold) opens with the Picasa viewer as you'd expect. It's just that the left click behaves differently for some reason. Any ideas on how to fix this?

  • win2008 r2 enterprise "Message Queuing" "Access is denied" "The list of messages cannot be retrieved"

    - by gerryLowry
    on my win7, I run compmgmt.msc and drill to a private queue folder ... when I click "Queue messages" or "Journal messages", I either see the messages, or "There are no items to show in this view". BUT, on win2008 R2 Enterprise, I run compmgmt.msc and drill to a private queue folder ... when I click "Queue messages" or "Journal messages", I see "There are no items to show in this view" which AFAIK is correct BUT I get this unwanted dialog: Message Queuing x ------------------------ (X) The list of messages cannot be retrieved. Error: Access is denied. [[ OK ]] On both computers, I'm a member of local Administrators. I'm concerned as a developer because I'm very soon going to be testing WCF/MSMQ software that works on my Win7 laptop. How to I get past this denied access problem? thnx / g.

  • Hiding some users in the user list of the OSX 10.6 login panel

    - by Lohoris
    Is there a way to show only some users in the login panel? I'm using OSX 10.6, and if I recall correctly I did something like that in a distant past but I really can't find out how. In the system preferences there seem to be nothing like that (neither in Accounts nor in Security, for instance), and Tinkertool does not do that. Google didn't help. edit: I hoped there was a graphical solution, such as while hiding them from the first screen, having also a button like "show all". I guess there isn't or somebody would have answered. Maybe I'll just change the usernames adding leading Z at the start of the usernames of the ones to "hide", so they'll appear lower in the list... :/

  • Simple one-way synchronisation of user password list between servers

    - by Renaud Bompuis
    Using a RedHat-derivative distro (CentOS), I'd like to keep the list of regular users (UID over 500), and group (and shadow files) pushed to a backup server. The sync is only one-way, from the main server to the backup server. I don't really want to have to deal with LDAP or NIS. All I need is a simple script that can be run nightly to keep the backup server updated. The main server can SSH into the backup system. Any suggestion? Edit: Thanks for the suggestions so far but I think I didn't make myself clear enough. I'm only looking at synchronising normal users whose UID is on or above 500. System/service users (with UID below 500) may be different on both system. So you can't just sync the whole files I'm afraid.

  • Media Player is missing from the list in "Turn Windows features on or off"

    - by arsaKasra
    I decided to reinstall Media Player in Vista [this way], so I figured I should turn it off as a Windows feature. But when I continue with the procedure, I get an incomplete list of features, here's an image: I looked around a bit, wondering if that is only an option available in 7, and I have seen people saying different things. So, is this only available for 7 or is there something wrong going on here? Can I make Media Player to show up in here? I am on a Toshiba Satellite A100 with Vista Home Premium OEM. I don't have my recovery disks or any restore point. Just to mention, I currently do have Media Player and it's working fine. Sorry if I can't think of any more details to add, please ask me for anything I should have included.

  • Apt-Get "sources.list needs at least 1 source-URI" error when building dependecies for Xen

    - by Entity_Razer
    What i'm trying to do is install Xen in a test environment, now I am trying to run the: apt-get build-dep xen-3.3 command, but it keep throwing a error which literally translated from dutch (installed the debian OS in Dutch) say's: E: your sourcelist (/etc/apt/sources.list) has to contain at least 1 source-URI I've googled it but I can't seem to find a definitive solid answer on how to fix this. By default a source-URI (read man page of apt-get) states it needs to be something along the lines of deb ftp://ftp.debian.org/debian stable contrib Now I've got 2 HTTP sources (default Debian ones) up & running so far and they've been working flawlessly for the better part of a few days now. Only now its starting to act up. Anyone able to help me out ? Much obliged !

  • SQL Server Management Studio Connect to Server List Editing

    - by Paul Farry
    I'm using SQLServer Management Studio (2005) and I have a fairly lengthy list of servers in there, and I'd like to get rid of some of them that are no longer in use, without having to set them all up again. I know that the C:\Users\*\AppData\Roaming\Microsoft\Microsoft SQL Server\90\Tools\Shell\mru.dat can be deleted and this will remove ALL the entries, but is there anyway to just delete some of them? (Coding info) I looked at the file and it is a serialised blob from the Microsoft.SqlServer.Express.ConnectionDlg.dll (Class Personalization) in the Appplication directory, but all the methods are private. So I can't just create an instance of this and then call Remove on the entries. Update I have written an Article on CodeProject explaining How this can be achieved. http://www.codeproject.com/KB/vb/AlterSQL2005MRU.aspx

  • What single piece of software do you most admire, and why?

    - by Burton
    As a developer, I too often find fault with the software that I use day to day. Unintuitive interfaces, etc. But there are those rare exceptions. Regardless of whether the software in question is a programmers' tool, tell me about software you have used: What has inspired admiration? What software made you re-remember simplicity? (or whatever gauge of awesomeness works for you). Only one piece of software per post, please.

  • virtualbox ftp hangs on list command

    - by Tiddo
    Hi all, I have virtual box installed on a windows 7 64-bit computer, with Cent OS 5.5 as guest os. I want to be able to use ftp between those. I've installed vsftpd on the guest os, and the guest os uses a nat connection with the host os for internet. So far, I am able to connect to the guest os using ftp (in filezilla), but after the list command is executed, nothing happens, until the command is timed out. This happens in both active and passive mode. I do have set a pasv_min/max_port in the vsftpd.conf file, listing is enabled, and the ports are redirected in virtualbox. Also the ftp_data_port is set to 20. I also tried setting the pasv_address, but I had to set it to 127.0.0.1, but than filezilla gives me this: Command: PASV Response: 500 OOPS: bad family Command: PORT 127,0,0,1,139,204 Response: 500 OOPS: child died Can someone help me with this?

I hope you can help me fix it. There is another problem. I don't know if this is related. For each blank line in my .bash_profile I get a : command not found. I commented them out and was fine.

  • Obtaining list of files from php script?

    - by SenorSputnik
    Naenara/KCCKP offers a catalog of hundreds of mp3 files that can only be downloaded in small amounts at a time. Clicking on a song title invokes mp3player.php and downloads a plaintext link to the mp3 file: http://www.kcckp.net/mp3player.php?e+8 Going directly to mp3player.php will display Korean error messages and send you back 1 page in your history. Is there any way to parse/coax mp3player.php into dumping a full list of mp3 links? I am sorry if this is a painfully easy or impossible task, I have not even begun to delve into php. </newbiewhining>
