    - by Aragon N
    i have an ubuntu network machine which has release of 10.04.1 LTS Lucid. on this system i have apache, postgresql and django. for some app. development i have to install php and php-curl... due to being on network, i have exported wmvare machine to internet and firstly i have upgraded system and then install php5 packages on it. After all replacing it with its old place, i have considered that the new system query is some slow according to another. Old system query time : 140 ms New system query time : 9.11 s i have checked /etc/network interface and it seems there is no problem. i have checked /etc/resolv.conf and it seems ok i have checked /etc/nsswitch.conf and only host section is different from old one which old system has hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 and then i have checked time host -t A services.myapp.com and i got real 0m0.355s user 0m0.010s sys 0m0.020s and now what can i have to check for boosting my system as before?

  • Why can't I ping server? VMware set to 'Bridged' loses IP address

    - by Dave
    I have installed a fresh 10.04 server onto a laptop on a home network as a VMware machine and set network connection to 'Bridged: connect directly to the physical network' from within VMware and rebooted the server. It then loses its IP address. dhclient eth0 says "No working leases in persistent database - sleeping" DHCP is working fine on the wi-fi router. The laptop is wired to a wireless router and from there wirelessly to a desktop. Desktop and Laptop can ping each other from Windows. I can ping the VM from Windows on the same laptop, but not from the desktop. Strangely ping has started to resolve hostnames to IPv6 addresses and not IPv4. Don't know whether that's connected? A kick in the right direction would be greatly appreciated. I've been an Ubuntu desktkop user for a few years, but new to ubuntu servers.

  • Wireless Connection Troubles

    - by James
    I just recently switched from Windows 7 over to Ubuntu 12.04 and have been experiencing some issues connecting to my home's wireless network. The only way I can get it to connect to the network is by disabling IPv4 and IPv6 settings. Even then while it says its connected to the network (3 bars), I'm unable to access the Internet. It connected for a little while after I first installed Ubuntu, but after the first reboot I haven't been able to access the web at all. I have very basic knowledge when it comes to computers and barely any when dealing with Ubuntu and Linux. I'm very happy with Ubuntu apart from this one issue, as before my computer was overheating and crashing, I've yet to experience any of those problems since installing Ubuntu. The information I can give may be very limited since I'm having to use my cell phone to figure out the solution to this. Any help would be greatly appreciated. Thanks in advance!

  • Optimizing a thread safe Java NIO / Serialization / FIFO Queue [migrated]

    - by trialcodr
    I've written a thread safe, persistent FIFO for Serializable items. The reason for reinventing the wheel is that we simply can't afford any third party dependencies in this project and want to keep this really simple. The problem is it isn't fast enough. Most of it is undoubtedly due to reading and writing directly to disk but I think we should be able to squeeze a bit more out of it anyway. Any ideas on how to improve the performance of the 'take'- and 'add'-methods? /** * <code>DiskQueue</code> Persistent, thread safe FIFO queue for * <code>Serializable</code> items. */ public class DiskQueue<ItemT extends Serializable> { public static final int EMPTY_OFFS = -1; public static final int LONG_SIZE = 8; public static final int HEADER_SIZE = LONG_SIZE * 2; private InputStream inputStream; private OutputStream outputStream; private RandomAccessFile file; private FileChannel channel; private long offs = EMPTY_OFFS; private long size = 0; public DiskQueue(String filename) { try { boolean fileExists = new File(filename).exists(); file = new RandomAccessFile(filename, "rwd"); if (fileExists) { size = file.readLong(); offs = file.readLong(); } else { file.writeLong(size); file.writeLong(offs); } } catch (FileNotFoundException e) { throw new RuntimeException(e); } catch (IOException e) { throw new RuntimeException(e); } channel = file.getChannel(); inputStream = Channels.newInputStream(channel); outputStream = Channels.newOutputStream(channel); } /** * Add item to end of queue. */ public void add(ItemT item) { try { synchronized (this) { channel.position(channel.size()); ObjectOutputStream s = new ObjectOutputStream(outputStream); s.writeObject(item); s.flush(); size++; file.seek(0); file.writeLong(size); if (offs == EMPTY_OFFS) { offs = HEADER_SIZE; file.writeLong(offs); } notify(); } } catch (IOException e) { throw new RuntimeException(e); } } /** * Clears overhead by moving the remaining items up and shortening the file. */ public synchronized void defrag() { if (offs > HEADER_SIZE && size > 0) { try { long totalBytes = channel.size() - offs; ByteBuffer buffer = ByteBuffer.allocateDirect((int) totalBytes); channel.position(offs); for (int bytes = 0; bytes < totalBytes;) { int res = channel.read(buffer); if (res == -1) { throw new IOException("Failed to read data into buffer"); } bytes += res; } channel.position(HEADER_SIZE); buffer.flip(); for (int bytes = 0; bytes < totalBytes;) { int res = channel.write(buffer); if (res == -1) { throw new IOException("Failed to write buffer to file"); } bytes += res; } offs = HEADER_SIZE; file.seek(LONG_SIZE); file.writeLong(offs); file.setLength(HEADER_SIZE + totalBytes); } catch (IOException e) { throw new RuntimeException(e); } } } /** * Returns the queue overhead in bytes. */ public synchronized long overhead() { return (offs == EMPTY_OFFS) ? 0 : offs - HEADER_SIZE; } /** * Returns the first item in the queue, blocks if queue is empty. */ public ItemT peek() throws InterruptedException { block(); synchronized (this) { if (offs != EMPTY_OFFS) { return readItem(); } } return peek(); } /** * Returns the number of remaining items in queue. */ public synchronized long size() { return size; } /** * Removes and returns the first item in the queue, blocks if queue is empty. */ public ItemT take() throws InterruptedException { block(); try { synchronized (this) { if (offs != EMPTY_OFFS) { ItemT result = readItem(); size--; offs = channel.position(); file.seek(0); if (offs == channel.size()) { truncate(); } file.writeLong(size); file.writeLong(offs); return result; } } return take(); } catch (IOException e) { throw new RuntimeException(e); } } /** * Throw away all items and reset the file. */ public synchronized void truncate() { try { offs = EMPTY_OFFS; file.setLength(HEADER_SIZE); size = 0; } catch (IOException e) { throw new RuntimeException(e); } } /** * Block until an item is available. */ protected void block() throws InterruptedException { while (offs == EMPTY_OFFS) { try { synchronized (this) { wait(); file.seek(LONG_SIZE); offs = file.readLong(); } } catch (IOException e) { throw new RuntimeException(e); } } } /** * Read and return item. */ @SuppressWarnings("unchecked") protected ItemT readItem() { try { channel.position(offs); return (ItemT) new ObjectInputStream(inputStream).readObject(); } catch (ClassNotFoundException e) { throw new RuntimeException(e); } catch (IOException e) { throw new RuntimeException(e); } } }

  • Sharing samba-folder with root access

    - by Industrial
    Hi everyone, I have a staging server in my network running Ubuntu server 10.10, being my main development area. As I need to access the files in the Apache root from other computers in the network, I have setup samba with the following settings: [www] comment = Apache root www path = /var/www writable = yes force user = root force group = root On the host computer, running Ubuntu 10.10 desktop, I am trying to mount the drive with a bash file looking like below: #!/bin/bash sudo mount -t cifs //192.168.1.5/www /media/www/ -o username=myusername,password=mypassword,rw,iocharset=utf8,file_mode=0777,dir_mode=0777 What happens is that I get mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) thrown in my face whilst trying to execute the mount. I've done exactly the same, with exactly the same smb.conf & mount-bash file on another computer in my network, but this just wont work. What am I doing wrong? I am running out of ideas.

  • How do I get my Broadcom BCM4313 working correctly?

    - by Ataraxio Panzetta
    I've installed ubuntu on a Asus 1015 netbook. Everything worked out of the box except for the Wireless adapter, which i had to install with the Additional Drivers application. It apparently installed fine and connects to our wireless network, but it only works at a "funny" speed range that goes from 367Bytes to a peak of 3Kb in its best moments. I know for sure the problem is neither the network nor the hardware. Network speeds are normal under windows on this laptop and in other computers with ubuntu aswell. lspci says the card is a BCM4313 model, but the Addittional Drivers Manager says these packecege contains Broadcom 802.11 Linux STA wireless driverfor use with Broadcom's BCM4311-, BCM4312-, BCM4321-, and BCM4322 based hardware seems like it installed the wrong driver... Is there anything I can do? I'm not concerned about compiling the driver or stuff like that, but I'm not sure on where to start... any help or guidance will be very, very appreciated.

  • Other people's files showing up in rhythmbox

    - by Avery Boyer
    I have my computer connected to a college network, and right now files that belong to other individuals on campus are showing up under Shared in rhythmbox. This is driving me up the wall, I absolutely despise the idea that files are being thrown around on the network and that other people's s*** is showing up on my computer, and that they may be able to see my files as well. This is a very, very serious problem as far as I am concerned and I want to know how I can ensure that I am sharing nothing with the network in the way of files on my computer and that no one else's files are showing up on my computer.

  • Passing data between engine layers

    - by spaceOwl
    I am building a software system (game engine with networking support ) that is made up of (roughly) these layers: Game Layer Messaging Layer Networking Layer Game related data is passed to the messaging layer (this could be anything that is game specific), where they are to be converted to network specific messages (which are then serialized to byte arrays). I'm looking for a way to be able to convert "game" data into "network" data, such that no strong coupling between these layers will exist. As it looks now, the Messaging layer sits between both layers (game and network) and "knows" both of them (it contains Converter objects that know how to translate between data objects of both layers back and forth). I am not sure this is the best solution. Is there a good design for passing objects between layers? I'd like to learn more about the different options.

  • dhcpd fails to start

    - by TECHPREACHER
    I recently installed Ubuntu 11.10 I then used apt-get to grab isc-dhcp3. I removed Network-Manager and manually configured my network interface eth0. In addition, I hand edited a dhcpd.conf file and designated eth0 as the listen port in /etc/default/isc-dhcp-server. However, each time I attempt to start dhcpd it fails. When I view the syslog file, the last line is as follows: "Not configured to listen on any interfaces!" My eth0 interface works fine. I can ping addresses inside and outside the network and perform DNS queries. Any help would be greatly appreciated. AJ

  • No keyring secrets found for [ssid] /802-11-wireless-security, ubuntu 12.04

    - by acimer
    I'm on Ubuntu 12.04 x64bit, installed it couple of days ago. The issue i'm having is this: on startup it connects to my wireless without a problem, but after a while I am disconnected and prompted to enter the key for the wireless network (which is entered - saved) so i just click 'ok', but wireless doesn't connect again. Reseting network manager doesn't help either. Only restart, after which, ubuntu connects to the said wireless without a problem. Terminal outputs this error message: ** Message: No keyring secrets found for cimermanovic /802-11-wireless-security; asking user. cimermanovic is the ssid name. also, here are some error messages that network manager is giving: (nm-applet:31926): GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion `dest_width 0' failed (nm-applet:31693): GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion `dest_width 0' failed (nm-applet:30184): GdkPixbuf-CRITICAL **: gdk_pixbuf_scale_simple: assertion `dest_width 0' failed What should i do to fix this?

  • 12.04 in Virtualbox is keep losing my wireless connection

    - by Derek
    I've Windows 7 as the Host OS, Ubuntu 12.04 as the guest and a Netgear WG111v2 as the USB Wireless device. Its connected to an open Wi-Fi network at work to bypass my works crazy strict filtering, When on the domain. I currently have network eth0 turned off in the virtualbox settings so the only network source would be through the USB device at wlan1. Its odd but the wireless seems extremely temperamental, I constantly have to ifconfig wlan down then ifconfig wlan1 up to get it back online. I know this might be super vague just curious if anyone has tried something like this or run into anything like it to point me in a direction I might not be seeing.

  • Share between Ubuntu machines

    - by Anero
    I'm sure it might be a very easy way to do this, but I haven't found how... I have two machines with Ubuntu 10.10 on the same network (just workgroup, no domain involved). On one of them I have shared a folder through Nautilus Folder Sharing. When opening the Network place on the second machine, I cannot see the first one listed, just Windows Network and when going into this folder I can see the Workgroup though when trying to go into it I get an Unable to mount. Failed to retrieve share list from server error. Is it required to do something else when sharing the folder through Nautilus?

  • Sidestep Automatically Secures Your Mac’s Connection on Unsecure Networks

    - by Jason Fitzpatrick
    If you’re wary of browsing on wide open public Wi-Fi networks (and you should be), Sidestep is a free Mac application that routes your connection on an unsecure network through a secure proxy. Sidestep automatically detects when you are on an unprotected wireless network and forms an encrypted tunnel to the proxy you specified during setup. Anytime you login a wide open Wi-Fi node (such as at a coffee shop, airport, or other public area) you won’t be broadcasting your login credentials and other personal information in what amounts to plain text into the air around you. Anyone snooping on you or the network in general will simply see your stream of encrypted data going to the proxy. Hit up the link below to grab a copy and read additional information about setting up the program and finding/configuring a proxy server. Sidestep is freeware, Mac OS X only.

    I have been trying to no avail, to share folders on my ubuntu pc with a windows network. The windows network isn't a homegroup, just a straight up access to folders made public. I can see the ubuntu shares I make, but when I try to access them I get a permission denied contact your system administrator type message. Could someone clarify the area re adding a user to samba, as there are about 30 different unix usernames! I just want my windows network to have unrestricted access to my linux folders.

  • Putting Ubuntu Server on to a networked HDD

    - by SimplySimon
    Firstly, I know very little about servers and secondly the 1Tb HDD I have has network capabilities, but no software is installed on it, so when connected to the computer it is seen as a network connection, but not as a drive. Any advice on how to get started would be great. Up until now, I have been using it as a USB drive which worked well, but when this is sorted, I would like it to be connected directly to our BT HomeHub accessible through the WiFi for all the family to use as a film and back up repository. I would then be able to set up individual accounts for each family member to use and may be, if possible, make it accessible from outside locations. The First question then is: How can I install Ubuntu server on the 1Tb HDD attached directly to the computers network port but which doesn't show up in Nautilus?

  • Slow writing HDD speed, Ubuntu 12.04 64-bit, Thinkpad T520i

    - by pyc
    It seems that (but I'm not completely sure), that when I'm copying files from gigabit network to HDD, I can't use full potential of the network which in my case is about 60 MB/s, because HDD writing is so slow like lower than 10 MB/s, and also it's slowing down the whole system which becomes pretty much unresponsive, almost impossible to work with. Copying files to samba share residing at Ubuntu machine, connected to share from Windows 7, I'm completely sure my network equipment is OK, and there's no CPU intensive process on Ubuntu except smbd getting about 10-20% from time to time which I think is OK. Something here is burried deep I think, maybe even in kernel. Already tried to switch from AHCI to compatibility mode, and turning acpi on and off - nothing helped. So it's like HDD buffer is full and emptying slowly while machine is sluggish, load is about 3 to 4. Somebody experienced the similar problems? Some help on troubleshooting process and identifying the cause would be helpful too :) Thanks!

  • Android - Multiplayer Game - Client / Server - Java etc

    I must write a multiplayer pong game for the school. Where are thousand of rooms and where two players can go in to a room and play together and collect points. I programmed the Pong game using Java (LibGDX). How can I do the Network part. I searched the web. And I came across Kryonet. Is there something better? What should I google. On the Internet there are a lot of those questions. And no good answers. I hope that this most questions can be answered. If someone has actual Open Source network game links, tutorials, books, network tutorial, etc. All this would help everyone. Thank you.

  • Wireless/Bluetooth problems on t43p

    - by user75965
    I have been struggling to get my wireless mini pcmcia card recognised by 12.04. It suddenly stopped, mid session. I have taken it out and replaced with a couple of spares with slightly different serial numbers. One had no joy - 'unauathorised'. The other worked briefly for thunderbird but not firefox, it seemed. The network controller reads like this: 0b:02.0 Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05) I have ordered a replacement from ebay, and hope I got the right one - used the the FRU number from the one that stopped working. But I have ALWAYS had no joy with my Thinkpad t43p Bluetooth and Ubuntu ( 12.04, and even 11.04 and 11.10, if I remember rightly). Do you think the Bluetooth problem will solve with a new mini pcmcia? Surely not, as it has never worked, whereas Wireless worked until a couple of weeks ago...
