• Which Linux distributive could you advise for a webserver with PIII-700MHz and 512Mb RAM?

  - by Andrei

  Hi everybody, We need to update our webserver (PIII-700MHz and 512Mb RAM) and could not do that without reinstalling the whole system. However my choice to put Ubuntu 9.10 was probably not the best and the machine works very slow now. Actually, we need it just for simple LAPM configuration and we really want to use the old box for this purpose. It used to have old version of Linux Slackware in which I didn't manage to update PHP due to a very complicated non-standard setup. What would you recommend?

• NIC: Changing Link Speed & Duplex to Full Duplex Is Drastically Slower

  - by rism

  I have an old Win Xp box with a 100 PRO/100 VE NIC and connecting to a Win 7 box with gigabit NIC via an ASUS gigabit router and peer to peer. I was getting 76% network utilisation on the XP machine using AUTO as the value for Link Speed and Duplex which is fine. But I decided to see what would happen if i selected Full Duplex 100Mbps on the XP box. I thought at worst it would be as good as auto detect since the Win 7 box it's transferring to is faster. Instead network utilisation dropped to 0.12% (as in a 10th of a percent) and the transfers just timed out. No biggie to reverse back to Auto but my question is why is full duplex such a dog? Im not "stuck" but just dont understand. There are only 2 machines here connecting through a router so i cant see how that would cause alot of collisions etc (if thats the problem).

• FTP client that supports 2 concurrent FTP sessions

  - by oninea

  I'm looking for an FTP client that can connect to two different FTP servers at the same time and allow file transfer or synchronization between those two servers. Basically what I want to achieve is to transfer/synchronize files between 2 different sites from my local machine. Are there any clients around that support this functionality? If there are none, is there an alternative to achieve this? I've taken a look at net2ftp, a web based FTP client, which provides almost the same functionality that I need. What I'm looking for though is a desktop app. Any ideas?

• Unable to Boot from USB External Hard Drive

  - by Josh Stodola

  I recently upgraded my main development machine to Windows 7. This involved wiping out my primary boot drive (Windows XP 64-bit) and starting clean. Before I wiped it, I did a direct disk-to-disk copy to a big external hard drive I have. While I have been able to migrate most of the necessary files without any problems, I was wanting to boot from it today to check a few settings. I plugged in the hard drive, rebooted, changed the BIOS to boot from USB-HDD first. But, no mattter what I do, it always boots from my primary drive to Windows 7. I do not see any kind of error message or anything. How can I boot to Windows XP 64-bit on this external hard drive?

• Robustly disabling specific cron.{hourly,daily,weekly} script

  - by benizi

  On various systems that I administer, there are cron scripts that get run via the commonly-used /etc/cron.{hourly,daily,weekly} layout. What I want to know is whether there's any common 'disable this script' functionality. Obviously, simply deleting something out of a given directory will disable it, but I'm looking for a more permanent solution. Deleting /etc/cron.daily/slocate will work to disable the nightly updatedb on my home machine (where I never use slocate), but next time I upgrade the slocate package, I'm pretty sure it'll reappear. The two distributions I'm most interested in are Gentoo and OpenSUSE, but I'm hoping there's a widely-implemented mechanism. Both distros as I have them use vixie-cron (not sure it matters).

• 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?

• tcpsndbuf high fail count

  - by Matthew Crenshaw

  I've got a small setup, one machine that acts as a load balancer and two machines that do all the work. The load balancer runs nginx (static content + php proxying to workers) and mysql, the two workers run php5-fpm and memcached (pooled between workers). Here's beancounters for the balancer: tcpsndbuf 2171848 2386280 10000000 20000000 3947733 tcprcvbuf 1248288 1669504 10000000 20000000 0 Here's worker 1: tcpsndbuf 951976 1262672 20000000 40000000 0 tcprcvbuf 278528 393496 20000000 40000000 0 Here's worker 2: tcpsndbuf 989888 527472 20000000 40000000 0 tcprcvbuf 212992 452520 20000000 40000000 0 The balancer has 1GB ram, the two workers have 2GB ram each.

• Windows Vista MAK keys and Volume Licensing..

  - by Physikal

  So when I go into the Volume Licensing Service Center and review our current used/available MAK activations, it says #/50. (the # being the number of our currently used). What I'm curious about, so far we only put vista on like 10 of our boxes. But over time, if we format a machine for some reason, then activate it, I'm assuming it will then in a way consume 2 keys? So what happens when we max the 50? Does that mean we have to fork over some more cash to M$? If so that's pretty lame.

• IIS 7.5 401 -UnAuthorized Access on a Virtual Directory

  - by Jimmy

  I have setup a website in IIS 7.5 on a Windows 2008 machine. The website is sitting on C:/websites/ Then I added a virtual directory called "/uploads" that points to "d:/websites/uploads". This directory holds all the images/media. When I browse the website in browser, I dont see any images etc. When I browse an image directly I notice that it's throwing a 401 error. 401 - Unauthorized: Access is denied due to invalid credentials. I have searched Google quite a lot and I am pretty sure I am have all the permissions setup correctly. Can anyone tell me what I could be doing wrong here?

• Temp profile used when User logs in

  - by TJ

  One of my users logged into his computer, Windows XP, last night only to be meet with an error message that it could not load his profile and he will be logged in using a temporary profile. Typically when this happens I shut the machine down and restart and the correct profile will load when they log in again. Not this time. In the user profile options under computer-properties-Advanced-user profiles it show that there are three profiles with his name. Two are the exact same size with the same modified date (5/5/10) and the other is what I would expect size wise for a new profile with a modified date of today. What are my options to restore his profile?

• Undeploy multiple SOA composites with WLST or ANT by Danilo Schmiedel

  - by JuergenKress

  As part of our current project the Build Management team asked for a solution to undeploy multiple composites at one time. Of course you have the “Undeploy All from This Partition” menu option in Enterprise Manager but since we have a lot of deployments every day the guys wanted to have a script solution. It is even more important for the nightly deployments on our continuous integration environment – strange, we couldn’t find anybody who wants to do the undeployment via Enterprise Manager manually every night ;-) However with WLST or ANT the SOA Suite comes with two options to undeploy composites via script. In this article I’d like to explain you both ways. Undeployment with WLST You can test the steps below on Oracle's Pre-built Virtual Machine for SOA Suite and BPM Suite 11g. Change to the WLST directory under MIDDLEWARE_HOME/Oracle_SOA1/common/bin. cd /oracle/fmwhome/Oracle_SOA1/common/bin/ Open WLST ./wlst.sh Connect to the SOA server Read the full article by Danilo Schmiedel SOA & BPM Partner Community For regular information on Oracle SOA Suite become a member in the SOA & BPM Partner Community for registration please visit  www.oracle.com/goto/emea/soa (OPN account required) If you need support with your account please contact the Oracle Partner Business Center.

• Windows Experience Index Dropped After Adding Dedicated Graphics Card

  - by Ludo

  I purchased a new PC with a Gigabye Z68X-UD3H-B3. I had a Radeon HD 5450 graphics card spare, so I've added that instead of using the onboard graphics as I just presumed it would be better. But, my windows experience index has gone down. From 5.4 to 5. Dekstop Performance has dropped from 5.4 to 5, although gaming graphics has gone up from 5.9 to 6.2. I'm not actually going to be using the machine for gaming, just audio production, but I added the card as I'll possibly be doing video editing in future too. Why would this be? Can I trust windows experience index scores? Or is it possible the onboard stuff is just better for general desktop stuff? Thanks! Ludo.

• Making files generally available on Linux system (when security is relatively unimportant)?

  - by Ole Thomsen Buus

  Hi, I am using Ubuntu 9.10 on a stationary PC. I have a secondary 1 TB harddrive with a single big logical partition (currently formatted as ext4). It is mounted as /usr3 with options user, exec in /etc/fstab. I am doing highspeed imaging experiments. Well, only 260fps, but that still creates many individual files since each frames is saved as one png-file. The stationary is not used by anyone other than me which is why the default security model posed by ubuntu is not necessary. What is the best way to make the entire contents of /usr3 generally available on all systems. In case I need to move the harddrive to another Ubuntu 9.x or 10.x machine? When grabbing image with the firewire camera I use a selfmade grabbing software-utility (console based) in sudo-mode. This creates all files with root as owner and group. I am logged in as user otb and usually I do the following when having to make files generally available to otb: sudo chown otb -R * sudo chgrp otb -R * sudo chmod a=rwx -R * This takes some time since the disk now contains individual ~200000 files. After this, how would linux behave if I moved the harddrive to another system where the user otb is also available? Would the files still be accessible without sudo use?

• How can I fix this configure error?

  - by balor123

  I'm trying to build mosh from source on a SUSE10 machine and am getting the following error: checking for protobuf... no configure: error: Package requirements (protobuf) were not met: No package 'protobuf' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables protobuf_CFLAGS and protobuf_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. I downloaded the source to protobuf and installed it in a custom path as well. I'm not using a package manager for any of this and cannot for various reasons outside the scope of the question. I added that custom path to my PATH and rehashed. Typically, this is enough for configure but in this case its not doing the trick. I added the prefix for protobuf to PKG_CONFIG_PATH but am still hitting this error. What should I do next to get past this error?

• Virtualization of desktop

  - by Agares

  Hi! I'm thinking about virtualization of my laptop(for educational purposes). My idea is to install very light host OS and have all the rest as virtual machines. Microsoft's Hyper-V Standalone would be very good solution, but it's impossible to access virtual machine from computer, where the Hyper-V is the host(isn't it?). So, which virtualization software would be good for me? I wanna have virtualized Windows 7(and maybe some other windowses). My processor support Intel Virtualization Technology.

• Make the sound louder in Lubuntu

  - by Andrew

  I have a Toshiba r835 running Lubuntu 11.10. Turning the volume slider up all the way doesn't give very loud sound. I've tried typing alsamixer in a terminal and turning up all the levels there to maximum, but the speakers are still fairly quiet. Is there a simple way to increase maximum volume in software? I understand that there are physical limits to the sound the laptop's speakers can produce, but I suspect my maximum volume is limited by software. EDIT: This is exactly the type of solution I'm looking for. However, it doesn't work for me. What I did: sudo pico /etc/asound.conf This file does not exist, so I create a new one, containing: pcm.!default { type plug slave.pcm "softvol" } pcm.softvol { type softvol slave { pcm "dmix" } control { name "Pre-Amp" card 0 } min_dB -5.0 max_dB 20.0 resolution 6 } I reboot the machine, and type alsamixer. I use my left/right arrow keys to inspect the various volume options. I expect to see a new option, called Pre-Amp, but I don't see one. This fix seems to work for other people. Why doesn't this fix work for me?

• Architecture- Tracking lead origin when data is submitted by a server

  - by Kevin

  I'm looking for some assistance in determining the least complex strategy for tracking leads on an affiliate's website. The idea is to make the affiliate's integration with my application as easy as possible. I've run into theoretical barriers, so i'm here to explore other options. Application Overview: This is a lead aggregation / distribution platform. We will be focusing on the affiliate portion of this website. Essentially affiliates sign up, enter in marketing campaigns and sell us their conversions. Problem to be solved: We want to track a lead's origin and other events on the affiliate site. We want to know what pages, ads, and forms they viewed before they converted. This can easily be solved with pixel tracking. Very straightforward. Theoretical Issues: I thought I would ask affiliates to place the pixel where I could log impressions and set a third party cookie when the pixel is first called. Then I could associate future impressions with this cookie. The problem is that when the visitor converts on the affiliate's site and I receive their information via HTTP POST from the Affiliate's server I wouldn't be able to access the cookie and associate it with the lead record unless the lead lands on my processor via a redirect and is then redirected back to the affiliate's landing page. I don't want to force the affiliates to submit their forms directly to my tracking site, so allowing them to make an HTTP POST from their server side form processor would be ideal. I've considered writing JavaScript to set a First Party cookie but this seems to make things more complicated for the affiliate. I also considered having the affiliate submit the lead's data via a conversion pixel. This seems to be the most ideal scenario so far as almost all pixels are as easy as copy/paste. The only complication comes from the conversion pixel- which would submit all of the lead information and the request would come from the visitor's machine so I could access my third party cookie.

• How do I add unmet dependencies for unity-lens-music autogen.sh?

  - by nickform

  I would like to build unity-lens-music on my newly-upgraded Ubuntu 12.10 machine. I followed these instructions from the unity website to get the code. The README was empty but I guessed that ./autogen.sh would be a sensible place to start. Unfortunately it exits with the following error: checking for LENS_DAEMON... no configure: error: Package requirements (glib-2.0 >= 2.27 gobject-2.0 >= 2.27 gio-2.0 >= 2.27 gio-unix-2.0 >= 2.27 dee-1.0 >= 1.0.7 sqlite3 >= 3.7.7 gee-1.0 json-glib-1.0 unity >= 6.90.0 unity-extras >= 6.90.0 tdb >= 1.2.6) were not met: No package 'dee-1.0' found No package 'sqlite3' found No package 'gee-1.0' found No package 'json-glib-1.0' found No package 'unity' found No package 'unity-extras' found No package 'tdb' found When I attempt to satisfy the dependencies that aren't found using apt-get install I either find that there is no exact match (e.g. 'dee-1.0' which matches several packages), I already have the latest version (e.g. sqlite3, unity) or there is no match at all (e.g. unity-extras and tdb). There is a later suggestion to modify PKG_CONFIG_PATH if I have installed software in a non-standard location but, to my knowledge, I have not. How should I proceed?

One time, machine rebooted (not manually), when I turn it on, it runs fsck on /dev/sdc2 and fix some errors and some files are missing on /dev/sdc2 I'v check /dev/sdc2 for badblocks, it doesn't have it ( using e2fsck -c /dev/sdc2 ) Here is the output of fsck http://pastebin.com/D5LmLVBY What else I can do to understand what's wrong here? BTW for /dev/sdc1 no message like that, in kern.log Linux version: 3.3.0 Distributive: Debian wheezy

• Visual Studio 2010 editor painfully slow [closed]

  - by Daniel Gehriger

  I'm running out of patience with MS VisualStudio 2010: I'm working on a solution containing ~50 C++ projects. When using the editor, I experience a lag of 1 - 2 seconds whenever I move the cursor to a different line, or when I move to a different window, or generally when the editor losses and gains focus. I went through a whole series of optimizations, to no avail: installed all hotfixes for VS2010 disabled all add-ins and extensions disabled Intellisense deleted all temporary files created by VS2010 disabled hardware acceleration unloaded all but 15 projects disabled tracking changes closed all but one window and so on. This is on a Dual Core machine with SSD harddrive (verified throughput 100MB/s), enough free space on HD, Windows 7 Pro 32-bit with 3GB of RAM and most of it still free. Whenever I type a letter, CPU usage of devenv.exe goes to 50 - 90% in process monitor for 1 - 2 seconds before returning to 5%. I used Process Explorer to analyze registry and file system access, and I only notice frequent accesses to the .sln file (which is quiet small), and a few registry reads, but nothing that would raise a red flag. I don't have this problem with solutions containing less projects, so I'm inclined to think that it's related to the number of projects. For your information, the entire solution has been migrated over the years from VS2005 to VS2008 to now VS2010. Does anyone have any ideas what else I could do to resume work on this project, other than returning to VS2008?

• Why is this static routing not working ?

  - by geeko

  Greeting gurus, I'm trying to develop a DHCP enforcement extension like Microsoft NAP. My trick to block dynamic-IP requesting machines (that don't meet certain policy) is to strip the default gateway (no default gateway) stated in the IP lease and set the lease subnet mask to 255.255.255.255. Now I need the blocked machines to be able to reach some specific locations (IPs) on the network. To allow for this, I'm including some static routes in the lease. For example, I'm including 10.10.10.11 via router 10.10.10.254 (the one to which the blocked machine that needs to access 10.10.10.11 is connected). Unfortunately, as soon as I set the default gateway to nothing, blocked machines cannot reach any of the added static routes. I also tried classless static routes. Any ideas ? any one knows how MS NAP actually do it ? Geeko

• Listing the routing table takes long time to complete

  - by Rafal Rawicki

  When I print routes defined on my computer using route, it takes about 5 to 20 seconds to complete. Why does it take so much time? With VPN enabled: $ time sudo route Kernel IP routing table (...) real 0m21.423s user 0m0.000s sys 0m0.012s With no VPN, this is about 5 seconds - still, computer can do a lot in this time. I've repeated my measurements few times, getting very similar results each try. My machine is Ubuntu with 3.0.0 kernel, but as far as I know, route on the other computers works the same way.
