• Ubuntu-installer fails preseed configuration file

  - by user76171

  I try to install Ubuntu 12.04 over network unattended. I installed a DHCP server (Dnsmasq), a TFTP server (tftpd-hpa), I got the netboot.tar.gz archive with the pxelinux.0 file, the pxelinux.cfg directory, the linux kernel and the initrd.gz image and I put a preseed file into my web server. Dnsmasq, tftpd-hpa, pxelinux and Apache are all on the same machine. The PCs MB doesn’t support PXE, so I use iPXE and boot it from a CD. The PC gets an IP from the DHCP, then iPXE loads #pxelinux.cfg/default, which I edited like this: timeout 5 prompt 0 default install label install kernel ubuntu-installer/i386/linux append vga=normal locale=en_GB setup/layoutcode=sl_SI console-setup/layoutcode=sl_SI netcfg/choose_interface=auto initrd=ubuntu-installer/i386/initrd.gz netcfg/get_hostname=ubuntux preseed/url=#http://192.168.10.10/ins/preseed.cfg Then it loads the linux kernel and the initrd.gz image. Then I got a question: Detect keyboard layout? I desided to bother with this later. So I answer No, and then twice on Englishjust to get trough and then I get to the error: The installer failed to process the preconfiguration file from #http://192.168.10.10/ins/preseeed.cfg. The file may be corrupt. I created the file myself and copied the d-I commands into it. I also tried to get the preseed.cfg over a web browser and it works fine. So why is the installer failing?

• What's so bad about pointers in C++?

  - by Martin Beckett

  To continue the discussion in Why are pointers not recommended when coding with C++ Suppose you have a class that encapsulates objects which need some initialisation to be valid - like a network socket. // Blah manages some data and transmits it over a socket class socket; // forward declaration, so nice weak linkage. class blah { ... stuff TcpSocket *socket; } ~blah { // TcpSocket dtor handles disconnect delete socket; // or better, wrap it in a smart pointer } The ctor ensures that socket is marked NULL, then later in the code when I have the information to initialise the object. // initialising blah if ( !socket ) { // I know socket hasn't been created/connected // create it in a known initialised state and handle any errors // RAII is a good thing ! socket = new TcpSocket(ip,port); } // and when i actually need to use it if (socket) { // if socket exists then it must be connected and valid } This seems better than having the socket on the stack, having it created in some 'pending' state at program start and then having to continually check some isOK() or isConnected() function before every use. Additionally if TcpSocket ctor throws an exception it's a lot easier to handle at the point a Tcp connection is made rather than at program start. Obviously the socket is just an example, but I'm having a hard time thinking of when an encapsulated object with any sort of internal state shouldn't be created and initialised with new.

• Troubleshooting wireless network connectivity

  - by taserian

  I'm currently running Ubuntu 10.10, and I'm running into trouble keeping my wireless connection alive. After rebooting, I get about 5-10 minutes of a good speed connection; afterwards, the connection just zeroes out. I've gotten around to stirring up a shell script that gives me another 10 minutes or so of connectivity. Script contents below: #! /bin/bash sudo ifconfig wlan0 up echo "Enabling wireless device . . ." sleep 5 sudo iwconfig wlan0 essid MyNetworkName echo "Connecting to network. . ." sleep 10 sudo dhclient wlan0 echo "Getting IP address. . ." sleep 5 echo "Done. Closing window. . ." sleep 5 Shortly after running the line "sudo iwconfig wlan0 essid MyNetworkName" from the script, I notice the speed pick up. Other computers in my home running Windows XP are not affected by this problem, so all indications point to my Ubuntu machine. Does anyone have any pointers as to how to resolve this?

• Virtually the fastest way to try Solaris 11 (and Solaris 10 zones)

  - by dminer

  If you're looking to try out Solaris 11, there are the standard ISO and USB image downloads on the main page.  Those are great if you're looking to install Solaris 11 on hardware, and we hope you will.  But if you take the time to look down the page, you'll find a link off to the Oracle Solaris 11 Virtual Machine downloads.  There are two downloads there:A pre-built Solaris 10 zoneA pre-built Solaris 11 VM for use with VirtualBoxIf you're looking to try Solaris 11 on x86, the second one is what you want.  Of course, this assumes you have VirtualBox already (and if you don't, now's the time to try it, it's a terrific free desktop virtualization product).  Once you complete the 1.8 GB download, it's a simple matter of unzipping the archive and a few quick clicks in VirtualBox to get a Solaris 11 desktop booted.  While it's booting, you'll get to run through the new system configuration tool (that'll be the subject of a future posting here) to configure networking, a user account, and so on.So what about that pre-built Solaris 10 zone download?  It's a really simple way to get yourself acquainted with the Solaris 10 zones feature, which you may well find indispensible in transitioning an existing Solaris 10 infrastructure to Solaris 11.  Once you've downloaded the file, it's a self-extracting executable that'll configure the zone for you, all you have to supply is an IP address for the zone.  It's really quite slick!I expect we'll do a lot more pre-built VM's and zones going forward, as that's a big part of being a cloud OS; if there's one that would be really useful for you, let us know.

• Syncing sharepoint 2010 with outlook

  - by uruit

  Technorati Tags: Sharepoint 2010,Outlook SharePoint offers the possibility to connect to content in a Document Library directly from Outlook, edit the documents offline and then sync when connection is restored. This is very useful if we are working at home and we want to access a shared document (ex. VPN connection settings) or continue working directly on a file. Steps to configure the connection: 1. Browse online to SharePoint Document library you want to connect and click on "Connect to Outlook": (click to enlarge) 2. Click Allow to confirm: 3. In Outlook you will see the documents as outlook email items with the ability to preview them. When a document is updated, Outlook will notify you that you have items unread. If you want to edit a file, the corresponding office tool (Word, Excel, PowerPoint) will ask if you want to update the server after saving a change, it is really straightforward. (click to enlarge) 4. Finally, I recommend to add the IP address of your SharePoint server in the secure sites in order to prevent Outlook to ask for your windows credentials every time you open Outlook: (click to enlarge) Outlook is a great tool, letting you work in a really integrated way, don't miss this amazing feature. This feature is also available in SharePoint Online :)   Post by: Marcelo Martinez UruIT (www.uruit.com/sharepoint_outsourcing.html) Leaders in Nearshore Outsourcing from South America

• Reproducible freezes with on an AMD fusion (e350) sony vaio

  - by doycho

  So a week ago I bought it and I've been struggling to make the Ubuntu which I installed stable. There's one thing that makes my life miserable, though. There's this easily reproducible freeze when I start some kind of video. So here is what happens: Everything works fine for some time I start vlc/mplayer/flashplayer/totem with something to watch In few minutes time I lose the sound (nothing in the logs at this point) At that time the video app instantly allocates all the memory and its CPU usage skyrockets. Total freeze. I can move the cursor around for few seconds and sometimes even switch to another app. But ultimately there comes the time I can't do anything - can't kill X with ctrl+alt+backspace (I have it enabled), can't switch to any other console (ctrl+alt+f1-6), can't connect to the machine via ssh. The only way to restart it is the ctrl+alt+SysRq+UABI magic :) What discourages me most is the fact I can't see anything in the logs. The only error I've noticed is Jun 19 17:00:37 serenity kernel: [ 1506.350676] software-center[17581]: segfault at 30 ip 00007fd3631b814c sp 00007fff18a6fa10 error 4 in libgtk-x11-2.0.so.0.2400.4[7fd362f7d000+436000]. I've been searching through the Xorg log, kernel logs, syslog. If you have any idea how I can get more debug info I'll be glad to try them. Things I've tried: Changing drivers - the open source one, the proprietary driver xorg-edgers' ppa - https://launchpad.net/~xorg-edgers/+archive/ppa changing to the last stable kernel (2.6.39) Some notes: It my be irrelevant but the sound is constantly stuttering. This probably is a separate issue though I've found that if I start more video/sound apps the freeze happens faster.

• django & postgres linux hosting (with SSH access) recommendations

  - by Justin Grant

  We're looking for a good place to host our custom Django app (a fork of OSQA) and its postgresql backend. Requirements include: Linux Python 2.6 or (ideally) Python 2.7 Django 1.2 Postgres 8.4 or later DB backup/restore handled by the hoster, not us OS & dev-platform-stack patching/maintenance handled by the hoster, not us SSH access (so we can pull source code from GitHub, so we can install python eggs, etc.) ability to set up cron jobs (e.g. to send out dail email updates) ability to send up to 10K emails/day good performance (not ganged up with a zillion other sites on one CPU, not starved for RAM) FTP or SCP access to web logs dedicated public IP SSL support Costs under $1000/month for a relatively small site (<5M pageviews/month) Good customer service We already have a prototype site running on EC2 on top of a Bitnami DjangoStack. The problem is that we have to patch the OS, patch postgres, etc. We'd really prefer a platform-as-a-service (PaaS) offering, like Heroku offers for Rails apps, where all we need to worry about is deploying our code instead of worrying about system software patching and maintenance. Google App Engine is closest to what we're looking for, but they don't offer relational DB access (not yet at least). Anyone have a recommendation?

• Problem connecting to isp server using xl2tpd as client. Ubuntu server 13.04

  - by Deon Pretorius

  I have followed guides found on google and ubuntu support pages and can get xl2tpd connection up but only under the following conditions: 1 - ADSL model must be configured and connected to the ISP or 2 - ADSL modem in bridge mode I must have an existing PPPoe connection established.

• using Moniker.com's nameservers

  - by user7519

  I have a VPS with A2Hosting for which i need to upgrade the OS. However, they've changed their VPS packages and forced me to order a new one. I went with an "unmanaged" package and have only just realised that they do not provide any DNS service at all, not even nameservers. Support tells me that "since your domain is not hosted with us, but with Moniker, you would not be able to use these nameservers. Your domain registrar should have a set of default nameservers that you can use, then create a A record to point to" my IP address. Moniker does provide for using their nameservers but i'm confused about which "pre-defined zone configuration" to use. They are: Domain Parking Domain Parking with Email Forwarding URL and Email Forwarding URL Forwarding URL Forwarding & CoolHandle Email I just want to use their nameserver and then create A & MX records pointing to the VPS. What do they mean by forwarding? I get the feeling it's a service that i don't want. Or, is it that i need to have a pre-defined zone only temporarily, and THEN set the A & MX? Which of these should i choose.

• Can't Start ISC DHCP IPv6 Server

  - by MrDaniel

  Trying to enable the ISC DHCP server for just IPv6 on Ubuntu 12.04 LTS. I have downloaded and installed the DHCP server via the following command: $ sudo apt-get install isc-dhcp-server Then I have followed the instructions in the following resources, Ubuntu Wiki DHCPv6, SixXS - Configuring ISC DHCPv6 Server and Linux IPv6 HOWTO - Configuration of the ISC DHCP server for IPv6 . So from review all those resources it seems like I need to: set a static IPv6 address for the Interface I want to run the DHCPv6 server from that is part of the IPv6 network subnet outside the DHCP range. Edit the /etc/dhcp/dhcpd6.conf file to configure the DHCPv6 range etc. Create the /var/lib/dhcp/dhcpd6.leases Manually start the DHCPv6 server. Setting the Static IP for eth0 $ sudo ifconfig eth0 inet6 add 2001:db8:0:1::128/64 My dhcpd6.conf default-lease-time 600; max-lease-time 7200; log-facility local7; subnet6 2001:db8:0:1::/64 { #Range for clients range6 2001:db8:0:1::129 2001:db8:0:1::254; } Created the dhcpd6.leases file As indicated in the dhcpd.leases man page. $ touch /var/lib/dhcp/dhcpd6.leases #Tried with sudo as well Manually starting the DHCPv6 server. Attempted to start the server using the following command: $ sudo dhcp -6 -f -cf /etc/dhcp/dhcpd6.conf eth0 The problem, the DHCP will not start, with an append error for the dhcpd6.leases file as indicated below when running the manual start command noted above. Can't open /var/lib/dhcp/dhcpd6.leases for append. Any ideas what I might be missing?

• Reverse WiFi to Broadcast connection coming from a USB device

  - by Daniel Clem

  I am using the app called Clockworkmod Tether. It connects using a script ( command line " gksu ./run.sh " ) on the computer. All my programs connect to the internet perfectly, minitube, midori, transmission torrents. But the network manager does not show any connection, wired or wireless. So this may cause issues? What I want to do is take this connection, and be able to share it some way, any way, by wireless. This Acer Timeline "Aspire 5810TZ" does have an Ethernet, so wired out to a router might be an option. But I would prefer to simply reverse the Wireless card to broadcast out to about 2 or 3 devices. Is this possible? Yes I have taken a look at the other questions already posted here, but the answers are 1 year old or older, and not clear at all. I am moderately comfortable (4.5 out of 10 ) on the command line. But pretty much need line by line directions for what commands are needed and what order, ect. Edit I have already tried the method of "Left click network manager, Create New Wireless Network" It is created fine, and I am able to connect to it with a tablet, but am un-able to get an outside connection with it. Using the "Shared to other computers" option because DHCP doesn't seem to work, and WEP Passphrase Security. I get an IP address on the connected device. But as I said, won't bring up any outside webpages or the like. So perhaps this is the wrong approach?

• multiple godaddy domains to home router then reverse proxy to multiple internal servers [closed]

  - by Dan

  I need someone to steer me correctly... advising on all required components. I have multiple domains with godaddy, say site1.com , site2.com, site3.net I have multiple home LAMP servers... one on say, lampsrv1 = 192.168.0.2:8080 (windows) and lampsrv2 = 192.168.0.3:9080 (linux srv2) I would like to have server1.site1.com point to lampsrv1 and server2.site1.com point to lampsrv2 . I may also want server1.site2.com also point to my lampsrv1 as an option. My thinking is - I have a dedicated linux srv1 with a reverse proxy server behind the router, ie Apache or NGINX or equivalent directing to appropriate LAMP server. It's the godaddy subdomains, cnames or redirections, etc I'm having a challenge with for starters... I have tested apache with virtual servers but can't get proxying to work based on host header info... seems to go to one address making me think its actually the apache reverse proxying that's not quite working. Finally to add to this, my router has a dynamic IP but does lease for quite a while but that would be my final piece. So, I'm sure this might be a popular question but can't seem to piece this together. I need someone who has actually configured this scenario to advise but will take other suggestions.... please indicate if you have successfully configured this.

• Bad archive mirror using PXE boot method

  - by user11566

  I'm trying to automatically install Ubuntu on a client PC by using the PXE BOOT method....my Objectives are below: I am following the steps given in this link installation using PXE BOOT the server will have a KICKSTART config file which contains the parameters for the OS installation and the files which are required for the OS installations. the client will have to detect this configuration along with the setup files and complete the installation without any input from the user. In my server I have installed DHCP3-server,Apache2 and TFTP to help me with the installation. I have nearly achieved my first objective, I am able to boot my client using the files stored in the server but during the installation stage it is asking me to CHOOSE A MIRROR OF UBUNTU ARCHIVE I gave the server's IP address and the path in the server where the files are located but then its giving me this error BAD ARCHIVE MIRROR So is it possible that instead of downloading all the files from the internet and storing them on my disk can I use the files which comes with the UBUNTU-CD, and how to store these files in what format (should I zip them) on the disk? secondly I am also generating the ks.cfg which I wanted to give to the client for automatic installation of the OS. So how should the configuration file be given to the installation process?

• Why is Ubuntu offline (except torrents) while Windows is online?

  - by Fahim al Islam

  I am using a static wired connection. Everything was perfect. But suddenly from few hours back I can't access any website. Dropbox, Ubuntu One also can't connect. Ping request is also unsuccessful, but I can download through torrent. I am not trying torrent download and browsing at the same time. So, I think it's not an issue about torrent using all the bandwidth. One important point is that this connection works perfectly on Windows on this same PC (My PC is dual-boot). I have tried the way what izx has suggested (using "sudo sh -c 'echo nameserver 8.8.8.8 /etc/resolv.conf'"), but I'm facing the same problem again. Now I can't even ping 8.8.8.8 and google.com. Though I can ping 74.125.228.2 (which is Google IP address) I can't understand what's happening and why this is happening. I'm new in this website many rules and regulations is unknown to me. So, please don't be bothered for my mistakes. Looking forward for help from anyone. Thanks to all.

• Cannot ping any computers on LAN

  - by Timothy

  I havem't been able to find a straight forward answer on this yet. I'm hoping people here are able to help! Keep in mind that I'm a complete beginner at this - this is the first installation i've done for any LINUX systems ever so please keep that in mind when answering this question. We are a complete Windows shop, using nothing but Microsoft products but looking into the value of OpenStalk however have been having problems getting Ubuntu Server installed and speaking to the network. The machine is getting an IP address which is telling me that some sort of DHCP activity is working but I'm not able to ping any computer on our network as well as not able to connect to the internet. Every time I try to ping i'm getting; Destination Host Unreachable I've tried using modifying the resolv.conf file with our static details to match my Windows 7 machine still with no luck. Even tried disabling the firewall on Ubuntu Server 11 and no luck. Any ideas? Please let me know if there is any information you need from the server and I'll post up.

• Need help with cybersquatting complaint: can a domain name forward AND resolve at same time? [on hold]

  - by Alan

  Probably a silly question for you pros... but for this novice here, I just want to make sure my understanding is correct. Context: I am trying to prove that a domain name owner has been cybersquatting and has never used the domain name in question. There are 4 shots from WayBackMachine over a three-year period that show the domain name resolving to a basic server index page with either no files or a single cgi-bin folder. The domain name owner claims, however, that the domain name was forwarded over the entire time from to another website, and that these captures probably coincided with occasional "outages." It is my understanding that: a) domain name forwarding is binary: if a domain name is forwarded to a valid site, it cannot simultaneously resolve to a valid IP address. Is this correct? b) domain name forwarding is not subject to "outages": servers can have outages, and websites can be down, but the forwarding itself cannot be down, as this is simply a pointer. (Or, the entire registrar where the DNS settings are hosted would have to malfunction. Is this correct? FINALLY, bonus question for pro webmasters: What is the likelihood that the WayBackMachine would capture the domain name on just those occasions when the webmaster disabled forwarding to supposedly work on the new site? Mucho thanks in advance!

• MySQL - Configuration

  - by Stuart Brierley

  Having previously detailed how to install MySQL Server, the next step is configuring MySQL. The MySQL configuration wizard can either be run immediately following installation from the MySQL installation wizard or manually from the Start Menu. Following the splash screen you can then choose whether to run a detailed or standard configuration. The detailed configuration allows you to create the optimal configuration for your specific machine, whereas the standard configuration creates a general configuration that can then be manually tuned. I chose detailed.   You are then asked to choose the type of server instance that is being configured. In this case it is a developer machine. Following this you are asked to choose the type of database usage that you expect on the server. I opted for multifunctional. You must then specify the location of the InnoDB tablespace.   Next specify the number of concurent connections to the server.   Now you must configure the networking options. I left the Strict mode enabled as this is the recommended option, but I disabled TCP/IP networking as I wanted to restrict this MySQL installation to the local machine only.   Set the character set that is best suited to your use - for me this was the default standard character set. Next up is the option to run MySQL as a service and whether or not to include the mysql dircetories in the windows PATH. I kept the install as a windows service option enabled, but unchecked the Launch MySQL server automatically option. This is because I only wanted MySQL running when I specifically want to use it. I also enabled the include in windows PATH option.   You can then change the security settings for the mysql installation. I opted to change the root password, disable root from local machines and disable annoymous access.   You are now ready to execute the configuration.   Once completed you should hopefully see the completed screen with lots of nice ticks against the various configuration tasks.

• Unable to print login-required images in IE

  - by Tim Fountain

  I have some images in a section of a site that require the user to be logged in in order to view. These images are served by a PHP script, which checks the user's login state and if valid, serves the binary data with the appropriate headers. This all works fine. The issue comes when a user tries to print one of these images. In Internet Explorer, when they go to print preview they get the broken image box with a red cross in the corner instead of the actual file. This is what gets printed also. All other browsers can print the images without issue. I have some images elsewhere on the site that are also served via. PHP but these don't require a login. These print fine. The PHP-powered HTML pages on the site that require a login also print fine in IE. It's just login-required images. The user hitting print preview does not seem to result in additional HTTP request to the server for the file. However I do see an additional HTTP request a few seconds later that comes from the same IP (may or may not be related), This request includes no host header, no REQUEST_URI and no user agent. The 'please login' page sends an appropriate 403 header. I've also added a far-in-future expires header to the image response itself to ensure that browsers can serve/print the files from their own cache but this hasn't made any difference. Why can't IE print the images and what else can I do to investigate or fix the problem?

• Can an internally developed fast evolving, agile, short sprint web application lend itself to offshoring?

  - by Gavin Howden

  I have recently been set a target to achieve readiness to successfully manage and deliver results through the usage of offshore teams on our mainline development project within 12 months. Our mainline is a multi-thousand user highly available web application, and various related SAAS components delivered through the above mentioned web application. We work agile on the mainline with a rapid 1 week sprint using continuous integration. Our delivery platform is a bespoke php framework, although we have some .net services and components in the mix. My view is: an offshore team could work if we either ship out an entire isolated project for offshore development, or we specify a component for our system in huge detail up front. But we don't currently work like that, and it will conflict with the in-house method, and unless the off-shore is working within our team, with our development/deployment chain it could be an integration nightmare. So my question is, given we have a closed source bespoke framework (Private IP) which we train our developers to use, and we work agile minimising documentation, maximising communication and responding to rapidly changing requirements, and much of the quality control is via team skills building and peer review, how can I make off-shoring work on our main line development?

• Wireless doesn't work after installing 11.10

  - by Ingram

  I just did a fresh install of 11.10 32 bit and I can't get my wireless to work. I installed the drivers the Broadcom STA wireless drivers through additional drivers and rebooted, but it still doesn't see any wireless networks Did something change in 11.10 that makes the wireless card not work anymore? I was using 10.10 before, and it worked fine. Do I need to go back to 10.10? sudo lshw -C network [sudo] password for user1: *-network description: Ethernet interface product: NetLink BCM5784M Gigabit Ethernet PCIe vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:03:00.0 logical name: eth0 version: 10 serial: 00:1f:16:be:55:ff size: 100Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm vpd msi pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.119 duplex=full firmware=sb v2.19 ip=192.168.0.70 latency=0 link=yes multicast=yes port=twisted pair speed=100Mbit/s resources: irq:43 memory:f0300000-f030ffff *-network UNCLAIMED description: Network controller product: BCM4311 802.11b/g WLAN vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:09:00.0 version: 01 width: 32 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:f0400000-f0403fff

• Missing driver ASUS PCE-N53 11n N600 PCI-E Adapter

  - by oyse

  I have problems with getting an Asus PCE-N53 11n N600 PCI-E Adapter card to work on my desktop computer. As far as I can tell no drivers are installed for the card. I know I can manually download the drivers directly from Asus, but I would rather not go that route. If there are anyone that knows about any packages or other things I can do to make this work would be much appreciated. Some systems details: $ lsb_release -a No LSB modules are available.

• Linux,Apache,NetBeans,PHP == Windows,IIS/Cassini,Visual Studio,ASP.Net

  - by Neil Smith

  I've worked out how to get my linux based Netbeans PHP development machine to behave much like what happens when you create a new ASP.Net project in Visual Studio. Firstly create multiple PHP project in Netbeans,say for example mysite1 and mysite2. Next edit the apache2/sites-enabled/000-default file and add two virtualhost sections as below <VirtualHost 127.0.1.1> ServerName mysite1.localhost DocumentRoot /var/www/mysite1/ </VirtualHost> <VirtualHost 127.0.2.1> ServerName mysite2.localhost DocumentRoot /var/www/mysite2/ </VirtualHost> For each site you add, pick a different ip address similar to the above where I use the third octet to increment, next edit the etc/hosts file and add the following two lines 127.0.1.1 mysite1.localhost 127.0.2.1 mysite2.localhost Then in Netbeans, go to File->Project Properties click on 'Run Configuration' and set 'Project Url' to http://mysite1.localhost for the first project and http://mysite2.localhost for the second project. That will give you a PHP development box which develops multiple PHP projects similar to how a Visual Studio Windows based box handles multiple ASP.Net sites. Hope this helps someone :)
