  • configuring lighttpd for large downloads

    - by ahmedre
    i run a web site that hosts pages that are just general scripts (php, etc) and mp3 downloads (some of which are fairly large - up to 200mb). i am running lighttpd on the servers on linux (ubuntu 64). everything is fine, but under high load, the server is not accessible (or very slow - even sshing in takes a while), and i am guessing this is due to a huge number of mp3 downloads at that time. consequently, dns sees the server as down and redirects all the traffic to the other servers, and after a while, it comes back up and things work again. so what's the best way to fix this? ideally, i want the server to continue running (and the web pages - php etc - to always work, but downloads don't always have to work). should i just have 2 web servers running (one for the downloads and one for the php pages), or is it perhaps something i can fix in my lighttpd configuration? here are the snippets from my configuration: server.max-worker = 4 server.max-fds = 2048 server.max-keep-alive-requests = 4 server.max-keep-alive-idle = 4 server.stat-cache-engine = "fam" fastcgi.server = ( ".php" => (( "bin-path" => "/usr/bin/php-cgi", "socket" => "/tmp/php.socket", "max-procs" => 1, "idle-timeout" => 20, "bin-environment" => ( "PHP_FCGI_CHILDREN" => "64", "PHP_FCGI_MAX_REQUESTS" => "1000" ), "bin-copy-environment" => ( "PATH", "SHELL", "USER" ), "broken-scriptfilename" => "enable" )) ) # normal php site $HTTP["host"] =~ "bar.com" { server.document-root = "/usr/local/www/sites/bar.com/" accesslog.filename = "|/usr/sbin/cronolog /var/log/lighttpd/%m/%d/%H/bar.log" } # download site $HTTP["host"] =~ "(download|stream).foo.com" { server.document-root = "/home/audio/" dir-listing.activate = "enable" dir-listing.hide-dotfiles = "enable" evasive.max-conns-per-ip = 1 evasive.silent = "enable" # connection.kbytes-per-second = 256 accesslog.filename = "|/usr/sbin/cronolog /var/log/lighttpd/%m/%d/%H/download.log" }

  • How to set up a easy-to-use proxy for the whole system with WinXP client and server?

    - by Pekka
    I am working together intensively with a colleague on the Canary Islands. We speak through live messenger and work together using a RDP software. She has frequent problems with connections to certain big-name and small-name sites (amongst others live.com, google.com, gmx.de) very likely to be caused by the spanish provider (the connections simply time out, this has been going on for weeks already). I have been thinking about setting up my computer as a proxy to make these connections work. I have a DSL connection and am behind a NAT capable router that I control. Does anybody know a simple, "one-click" way to transport ALL network traffic through a remote proxy? Without having to set proxy settings for each application that uses the internet? VPN is not an option, because I am behind a firewall that supports protocol 47 and such, but I have never succeeded in getting an incoming VPN connection to work. I can however redirect normal traffic using NAT. A VPN solution that does not need strange protocols would also be an option.

  • How to have current page selection using inludes navigation

    - by Anders Kitson
    I am using php includes to limit redundancy on my pages, how can I have my navigation have the current page selected with say a certain color for the HOME button when my navigation is called from a header.php file. If i were to say to add a "active" class to the home.php item and add a style so it looked different, that would happen across the board for all my pages, which is why I am using includes in the first place, how can I have one header.php file with my navigation, that also allows each page the ability to show the current page you are on reflected in the navigation? This is the nav portion of the header.php file <ul> <li><a href="index.php">About Us</a></li> <li><a href="portfolio.php">Portfolio</a></li> <li><a href="news.php">News</a></li> <li><a href="contact.php">Contact</a></li> </ul> This is the index.php file that the header.php file is included in <?php include("includes/header.php"); ?> <div class="span-8" id="welcome"> <p>Lorem ipsum</p> </div> <div class="span-16 last" id="slideshow"> <img src="images/introImage1.png" alt="fountain"> <img src="images/introImage2.png" alt="bench"> <img src="images/introImage3.png" alt="bridge"> </div> <?php include("includes/footer.php"); ?>

  • Does jQuery have a plugin to display a "message bar" like the Twitter "wrong password" bar at the to

    - by Jian Lin
    Twitter will pop down a message bar at the top of the screen say "Wrong password" and after 10 seconds, it will slide up and disappear. Chrome also shows "Do you want to save the password" message box using such a way. Does jQuery have a plug in to do that already? Does it also work in IE 6? Because usually, the display of relative to the viewport (using position: fixed) will not work on IE 6. thanks.

  • Unselecting RadioButtons in Java Swing

    - by Thomas
    When displaying a group of JRadioButtons, initially none of them is selected (unless you programmatically enforce that). I would like to be able to put buttons back into that state even after the user already selected one, i.e., none of the buttons should be selected. However, using the usual suspects doesn't deliver the required effect: calling 'setSelected(false)' on each button doesn't work. Interestingly, it does work when the buttons are not put into a ButtonGroup - unfortunately, the latter is required for JRadioButtons to be mutually exclusive. Also, using the setSelected(ButtonModel, boolean) - method of javax.swing.ButtonGroup doesn't do what I want. I've put together a small program to demonstrate the effect: two radio buttons and a JButton. Clicking the JButton should unselect the radio buttons so that the window looks exactly as it does when it first pops up. import java.awt.Container; import java.awt.GridLayout; import java.awt.event.*; import javax.swing.*; /** * This class creates two radio buttons and a JButton. Initially, none * of the radio buttons is selected. Clicking on the JButton should * always return the radio buttons into that initial state, i.e., * should disable both radio buttons. */ public class RadioTest implements ActionListener { /* create two radio buttons and a group */ private JRadioButton button1 = new JRadioButton("button1"); private JRadioButton button2 = new JRadioButton("button2"); private ButtonGroup group = new ButtonGroup(); /* clicking this button should unselect both button1 and button2 */ private JButton unselectRadio = new JButton("Unselect radio buttons."); /* In the constructor, set up the group and event listening */ public RadioTest() { /* put the radio buttons in a group so they become mutually * exclusive -- without this, unselecting actually works! */ group.add(button1); group.add(button2); /* listen to clicks on 'unselectRadio' button */ unselectRadio.addActionListener(this); } /* called when 'unselectRadio' is clicked */ public void actionPerformed(ActionEvent e) { /* variant1: disable both buttons directly. * ...doesn't work */ button1.setSelected(false); button2.setSelected(false); /* variant2: disable the selection via the button group. * ...doesn't work either */ group.setSelected(group.getSelection(), false); } /* Test: create a JFrame which displays the two radio buttons and * the unselect-button */ public static void main(String[] args) { JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); RadioTest test = new RadioTest(); Container contentPane = frame.getContentPane(); contentPane.setLayout(new GridLayout(3,1)); contentPane.add(test.button1); contentPane.add(test.button2); contentPane.add(test.unselectRadio); frame.setSize(400, 400); frame.setVisible(true); } } Any ideas anyone? Thanks!

  • Using Qt CSS to set own Q_PROPERTY(QFont)

    - by Kamil Klimek
    Hi there. I'm using Qt 4.6.2 and i have problem with QCSS. I have own Q_PROPERTY(QFont myFont READ myFont SET setMyFont). I want to change it with QCSS but it doesn't work. I've tried using normal font syntax but it doesn't work. I've also tried few other combinations like: qproperty-myFont: font(serif 20 1 0) font(serif 20 bold) QFont(serif 20 1 0) QFont(serif 20 bold) QFont(bold 20px serif) etc.

  • Have to login twice. PHP sessions and login troubles with Chrome and Opera.

    - by Robert
    The problem I am encountering is that for my login form I have to login twice for the session to register properly, but only in Chrome (my version is 4.0.249.89) and Opera (my version is 10.10). Here is the stripped down code that I am testing on: Login Page: session_start(); $_SESSION['user_id'] = 8; $_SESSION['user_name'] = 'Jim'; session_write_close(); header('Location: http://www.my-domain-name.com/'); exit(); Home Page: session_start(); if ( isset($_SESSION['user_id']) ) { echo "You are logged in!"; } else { echo "You are NOT logged in!"; } Logout Page: session_start(); session_unset(); session_destroy(); header('Location: http://www.my-domain-name.com/'); exit(); Currently, under a fresh load with no cookies, if I go to my-domain-name.com/login/ it will redirect to the home page and say "You are NOT logged in!" but if I go there again it will say "You are logged in!". Any ideas? Thanks for your help.

  • Many to many table design question

    - by user169867
    Originally I had 2 tables in my DB, [Property] and [Employee]. Each employee can have 1 "Home Property" so the employee table has a HomePropertyID FK field to Property. Later I needed to model the situation where despite having only 1 "Home Property" the employee did work at or cover for multiple properties. So I created an [Employee2Property] table that has EmployeeID and PropertyID FK fields to model this many 2 many relationship. Now I find that I need to create other many-to-many relationships between employees and properties. For example if there are multiple employees that are managers for a property or multiple employees that perform maintenance work at a property, etc. My questions are: 1) Should I create seperate many-to-many tables for each of these situations or should I just create 1 more table like [PropertyAssociatonType] that lists the types of associations an emploee can have with a property and just add a FK field to [Employee2Property] such a PropertyAssociationTypeID that explains what the association is? I'm curious about the pros/cons or if there's another better way. 2) Am I stupid and going about this all worng? Thanks for any suggestions :)

  • Trouble printing to local printer when connected to VPN with split-tunneling enabled

    - by Marve
    I'm a volunteer network admin for a multi-tenant non-profit office space. One of our new tenants uses a VPN to connect to remote resources using RRAS and Small Business Server 2008. They also have a local network printer for the workstations in our office. When connected to the VPN, they cannot print to the local printer. I informed their network admin that they need to enable split-tunneling to fix this. Their network admin enabled split-tunneling, but apparently printing still didn't work. He told me that I need to open port 1723 on our office firewall to allow it to work. I'm just a novice administrator and not familiar with RRAS, but this doesn't sound right to me and I haven't been able to find anything on the web to validate it. Additionally, my understanding of split-tunneling is that it is handled entirely by the VPN client and should work irrespective of firewall settings. Is my understanding of the situation incorrect? What steps should I take to resolve this problem?

  • Default value of a type

    - by viky
    For any given type i want to know its default value. In C#, there is a keyword called default for doing this like object obj = default(Decimal); but I have an instance of Type (called myType) and if I say this, object obj = default(myType); it doesn't work Is there any good way of doing this? I know that a huge switch block will work but thats not a good choice.

  • UDP Tracker not responding

    - by kelton52
    Alright, so I'm trying to connect to UDP trackers using c#, but I never get a response. I also don't get any errors. Here's my code. namespace UDPTester { class MainClass { public static bool messageReceived = false; public static Random Random = new Random(); public static void LOG(string format, params object[] args) { Console.WriteLine (format,args); } public static void Main (string[] args) { LOG ("Creating Packet..."); byte[] packet; using(var stream = new MemoryStream()) { var bc = new MiscUtil.Conversion.BigEndianBitConverter(); using(var br = new MiscUtil.IO.EndianBinaryWriter(bc,stream)) { LOG ("Magic Num: {0}",(Int64)0x41727101980); br.Write (0x41727101980); br.Write((Int32)0); br.Write ((Int32)Random.Next()); packet = stream.ToArray(); LOG ("Packet Size: {0}",packet.Length); } } LOG ("Connecting to tracker..."); var client = new System.Net.Sockets.UdpClient("tracker.openbittorrent.com",80); UdpState s = new UdpState(); s.e = client.Client.RemoteEndPoint; s.u = client; StartReceiving(s); LOG ("Sending Packet..."); client.Send(packet,packet.Length); while(!messageReceived) { Thread.Sleep(1000); } LOG ("Ended"); } public static void StartReceiving(UdpState state) { state.u.BeginReceive(ReceiveCallback,state); } public static void ReceiveCallback(IAsyncResult ar) { UdpClient u = (UdpClient)((UdpState)(ar.AsyncState)).u; IPEndPoint e = (IPEndPoint)((UdpState)(ar.AsyncState)).e; Byte[] receiveBytes = u.EndReceive(ar, ref e); string receiveString = Encoding.ASCII.GetString(receiveBytes); LOG("Received: {0}", receiveString); messageReceived = true; StartReceiving((UdpState)ar.AsyncState); } } public class UdpState { public UdpClient u; public EndPoint e; } } I was using a normal BinaryWriter, but that didn't work, and I read somewhere that it wants it's data in BigEndian. This doesn't work for any of the UDP trackers I've found, any ideas why I'm not getting a response? Did they maybe change the protocol and not tell anyone? HTTP trackers all work fine. Trackers I've tried udp://tracker.publicbt.com:80 udp://tracker.ccc.de:80 udp://tracker.istole.it:80 Also, I'm not interested in using MonoTorrent(and when I was using it, the UDP didn't work anyways).

  • OpenVZ with bridged interfaces and VLAN

    - by Deimosfr
    Hi, I've got a problem with OpenVZ with bridged VLAN. Here is my configuration: +------+ +-------+ +-----------+ +---------+ br0 |VE101 | | | | OpenBSD |----->| Debian |------->| | | WAN |--->| Router | | OpenVZ | +------+ | | | Firewall |----->| br0 br1 | br1 +------+ +-------+ +-----------+ +---------+------->|VE102 | |br0 | | |VLAN br0.110 +------+ v +---------+ |VE103.110| +---------+ I can't make VLAN work on br0 (br0.110) and I would like to understand why. I don't have any switch so no problem with unmanageable switch. I've configured a VLAN interface on OpenBSD in /etc/hostname.vlan110: inet 192.168.110.254 255.255.255.0 NONE vlan 110 vlandev sis1 And it seems to be working fine. I've also adapted my PF configuration to work with VLAN but I don't see any incoming traffic. On my Debian Lenny, here is my interfaces configuration : # The loopback network interface auto lo iface lo inet loopback # br0 auto br0 iface br0 inet static address 192.168.100.1 netmask 255.255.255.0 gateway 192.168.100.254 network 192.168.100.0 broadcast 192.168.100.255 bridge_ports eth0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off # VLAN 110 auto br0.110 iface br0.110 inet static address 192.168.110.1 netmask 255.255.255.0 network 192.168.110.0 gateway 192.168.110.254 broadcast 192.168.110.255 pre-up vconfig add br0 110 post-down vconfig rem br0.110 It looks OK, but when I start my VE, here is the message: ...

So I've got one error here. I've followed this documentation http://wiki.openvz.org/VLAN but it doesn't work. I've certainly missed something but I don't know why. Someone could help me please?

  • How can I proxy multiple LDAP servers, and still have grouping of users on the proxy?

    - by Chris
    I have 2 problems that I'm hoping to find a common solution to. First, I need to find a way to have multiple LDAP servers (Windows AD's across multiple domains) feed into a single source for authentication. This is also needed to get applications that can't natively talk to more than one LDAP server to work. I've read this can be done with Open LDAP. Are there other solutions? Second, I need to be able to add those users to groups without being able to make any changes to the LDAP servers I'm proxying. Lastly, this all needs to work on Windows Server 2003/2008. I work for a very large organization, and to create multiple groups and have large numbers of users added to, moved between, and removed from them is no small task. This normally requires tons of paperwork and a lot of time. Time is the one thing we don't normally have; dodging the paperwork is just a plus. I have very limited experience in all this, so I'm not even sure what I'm asking will make sense. Atlassian Crowd comes close to what we need, but falls short of having it's own LDAP front end. Can anyone provide any advice or product names? Thanks for any help you can provide.

  • creating a backup system with freenas

    - by masfenix
    We are currently in the process of opening a new accounting firm in the new year (actually moving from our previous location). I am looking for a cheap/free solution to back up our files (small, text files couple of kb). I was impressed with FreeNas and Windows Backup but I found out that Windows Backup only saves for a maximum of 2 years. The work machines will be running Windows 8 or Windows 7. There can be many work machines however we have only one to start with (ie, think of it as just one employee). I have an old core 2 duo with 2 gigs of ram that I can convert to a server if need be. I want the syncing to be done through LAN since the data is confidential and should never touch the outside world. So ideally, I would like the following scenario: A skydrive/dropbox like service to sync my client files over work machines and a central server. The "server" part should store history of files (i don't know how this will be done since the file will have the same name?). This isn't really necessary, but I can see it become useful. I am not familiar with RAID, so does any software RAID solution exist? I will most likely be buying 2 hard drives.

  • How I can fix the "Display Driver has stopped responding and has recovered"?

    - by Vitor Rangel
    I'm using a GeForce GTX 580, with Windows 7 64-bit. The driver version of the GTX is 301.42. The problem happens after a few minutes, when I'm playing specifc games. It won't happen in all games - And I don't have any idea why these games doesn't work. The games that doesn't work: Battlefield 3, Civilization V, Sniper Elite V2. The games that work: Mass Effect 3, Crysis 2, Team Fortress 2, Left 4 Dead 2, Skyrim, L.A. Noire. As you can see, it's not a problem of "The games that demand more stop working". I've tryed updating the driver of the graphics-card, the bios of the motherboard, even formated my computer (It was needing it) and instaled every driver in the last version possible. This problem happens since I bought my graphics-card, 6 months ago. After a few minutes, from 10 to 20, the pixels in the monitor become strange, with random colors and effects, like it was broken. Then, everything goes black, and the message appears "Display Driver has stopped responding and has recovered". After that, I need to close the game and start again. I am not overclocking, and my temperature never goes higher than 70ºC.
