• Change install path to /usr/bin instead of /usr/local/bin

  - by user1678788

  A simple question, but I have no concrete documentation to confirm my answer. When installing software with the make install command under a unix machine, the default path is going over to /usr/local/bin. I would like to update a package system-wide under /usr/bin. How (and where) do I change the command under make or make install to /usr/bin? Also - Can the package remain on /usr/local/bin but the systemwide usage of Python (the update being installed) be changed to /usr/local/bin from /usr/bin to avoid modifying the original installed version ?

• Order in which passphrase is asked for encrypted volumes

  - by Lars Kotthoff

  I have installed 12.10 on a machine with two disks. The root partition is on one disk, the swap partition on the other. Both disks are encrypted and I have added the corresponding entries to /etc/crypttab. During boot, it asks for the passphrase for the disk with the root filesystem. Then it continues booting and gets to the login screen before I get a chance to enter the passphrase for the other disk. After logging in, I verified that it was actually waiting for me to enter the passphrase for that second partition (askpass process is running). But at that point, I have no way of entering the passphrase anymore. The manpage for crypttab suggests that the order in which the volumes are specified matters, so I changed it to have the swap disk first. I updated the initramfs and grub afterwards, but it didn't make any difference. How can I specify the order in which the encrypted partitions are unlocked? I'm looking for a solution that either asks for the swap passphrase first or tells the system to wait until all encrypted partitions are unlocked before displaying the login screen.

• Test/Dummy SMTP server for Windows

  - by geoaxis

  I would like to install a Test/Dummy SMTP server on a Windows 2008 server (virtual box). I just want to test my web application on the machine it self so I don't need the mails to go out on the internet, but just to be written to disk (so that I can verify that the mail function was indeed called and the correct data was handed over to SMTP) Can you recommend some tool. I guess starting your own SMTP server in python is an option. I am looking for a simple (ready to use) solution, targeted for tests systems. I will need to integrate it to automated tests (Selenium) at a later stage. Thanks

• Script language native extensions - avoiding name collisions and cluttering others' namespace

  - by H2CO3

  I have developed a small scripting language and I've just started writing the very first native library bindings. This is practically the first time I'm writing a native extension to a script language, so I've run into a conceptual issue. I'd like to write glue code for popular libraries so that they can be used from this language, and because of the design of the engine I've written, this is achieved using an array of C structs describing the function name visible by the virtual machine, along with a function pointer. Thus, a native binding is really just a global array variable, and now I must obviously give it a (preferably good) name. In C, it's idiomatic to put one's own functions in a "namespace" by prepending a custom prefix to function names, as in myscript_parse_source() or myscript_run_bytecode(). The custom name shall ideally describe the name of the library which it is part of. Here arises the confusion. Let's say I'm writing a binding for libcURL. In this case, it seems reasonable to call my extension library curl_myscript_binding, like this: MYSCRIPT_API const MyScriptExtFunc curl_myscript_lib[10]; But now this collides with the curl namespace. (I have even thought about calling it curlmyscript_lib but unfortunately, libcURL does not exclusively use the curl_ prefix -- the public APIs contain macros like CURLCODE_* and CURLOPT_*, so I assume this would clutter the namespace as well.) Another option would be to declare it as myscript_curl_lib, but that's good only as long as I'm the only one who writes bindings (since I know what I am doing with my namespace). As soon as other contributors start to add their own native bindings, they now clutter the myscript namespace. (I've done some research, and it seems that for example the Perl cURL binding follows this pattern. Not sure what I should think about that...) So how do you suggest I name my variables? Are there any general guidelines that should be followed?

• The Ideal Platform for Oracle Database 12c In-Memory and in-memory Applications

  - by Michael Palmeter (Engineered Systems Product Management)

  Oracle SuperCluster, Oracle's SPARC M6 and T5 servers, Oracle Solaris, Oracle VM Server for SPARC, and Oracle Enterprise Manager have been co-engineered with Oracle Database and Oracle applications to provide maximum In-Memory performance, scalability, efficiency and reliability for the most critical and demanding enterprise deployments. The In-Memory option for the Oracle Database 12c, which has just been released, has been specifically optimized for SPARC servers running Oracle Solaris. The unique combination of Oracle's M6 32 Terabytes Big Memory Machine and Oracle Database 12c In-Memory demonstrates 2X increase in OLTP performance and 100X increase in analytics response times, allowing complex analysis of incredibly large data sets at the speed of thought. Numerous unique enhancements, including the large cache on the SPARC M6 processor, massive 32 TB of memory, uniform memory access architecture, Oracle Solaris high-performance kernel, and Oracle Database SGA optimization, result in orders of magnitude better transaction processing speeds across a range of in-memory workloads.

• How do I get write access to ubuntu files from Windows?

  - by Steven

  I'm running Ubuntu 11.10 on my Virtual Machine as a web server. I've mounted the W:/ drive in Win 7 to my /www folder in Ubuntu. I can read the files, but I'm not able to write to the files. In Samba, I have created the following user: <www-data> = "<www-data>" And given guest ok for the www folder: [www] comment = Ubuntu WWW area path = /var/www browsable = yes guest ok = yes read only = no create mask = 0755 ;directory mask = 0775 force user = www-data force group = www-data I've also run sudo chmod -R 755 www to make ensure correct rw access. What am I missing in order to get write access to my ubuntu files from Windows?

• Windows Server 2008: How to tell if a user is a 'local' use or a 'domain' user

  - by David

  I'm a developer, not a server admin, so please bear with me! I've been tasked with checking the installation of some software on a Windows Server 2008 R2 machine in the cloud, within two scenarios: There is no domain, the software will use local users and groups for authentication There is a domain, the software will use domain users and groups for authentication I've done part 1, but I'm puzzled about part 2. I've just installed the Active Directory Domain Services role on the server, so now I have a domain of one computer. When I look in Active Directory Users and Computers, I see all my original local users and groups. Have they now been 'promoted' to domain users? Or do I not have any domain users yet? Is there a way I can tell the difference between domain users and local users now? Thanks

• Thunderbird gives " Not enough disk space " alert, after trying to download more emails ( Win 7, 64 bit )

  - by James C

  So, today I have installed Mozilla Thunderbird 24.2.0 on my Windows 7 (64 bit) machine. It was downloading emails, until it hit an error. An alert showed up saying : "There is not enough disk space to download new messages. Try deleting old mail, emptying the Trash folder, and compacting your mail folders, and then try again." Now, disk space is not a problem, there is enough free space left ( almost 50 % of the drive ). How to stop the alert and continue downloading ?

• Dell Dimension running Fedora12 does a "Sleeping Beauty" and I am not a "handsome prince"!

  - by Jim Dobbs

  Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

• opening and closing connection with port happening fastly

  - by michale

  We have a Main application named "Trevor" installed in 2008R2 machine named "TEAMER12" which is slow now. One more application named "TVS" also running in and found there were many connections per second occurring to port 5009. netstat tool mentions that some fast connection open/close seen for port 5009 So first it will be listening mode like shown below TCP 0.0.0.0:5009 TEAMER12:0 LISTENING then establishes connection like TCP 127.0.0.1:5009 TEAMER12:49519 ESTABLISHED TCP 127.0.0.1:5009 TEAMER12:60903 ESTABLISHED After that iwill become TIME_WAIT and i could see several entries like shown below TCP 127.0.0.1:49156 TEAMER12:5009 TIME_WAIT after that it will establish connection like TCP 127.0.0.1:60903 TEAMER12:5009 ESTABLISHED TCP 127.0.0.1:64181 TEAMER12:microsoft-ds ESTABLISHED again it will go several entries like TIME_WAIT TCP 127.0.0.1:49156 TEAMER12:5009 TIME_WAIT Finally it will establish like this TCP 172.26.127.40:139 TEAMER12:0 LISTENING TCP 172.26.127.42:139 TEAMER12:0 LISTENING TCP 172.26.127.42:5009 TEAMER12:64445 ESTABLISHED TCP 172.26.127.42:64445 TEAMER12:5009 ESTABLISHED Can any body tell me whats the reason behind why many connections per second occurring to port 5009 and why application slow?

• Has anyone managed to install Office Webapps on SharePoint 2010, on Windows 7 ?

  - by Nick Haslam

  I've installed SharePoint 2010 as a development environment on my Windows 7 x64 environment (notes here) and would like to install Office Web Apps onto it also. However, when trying to install (following this link), I get an error saying that Web roles aren't installed. The error message in the log file is: Start C:\Windows\system32\ServerManagerCmd.exe -whatif -inputpath C:\Users\nickh\AppData\Local\Temp\PRE1.tmp.XML Error: Failed to start process for file: C:\Windows\system32\ServerManagerCmd.exe arguments: -whatif -inputpath C:\Users\nickh\AppData\Local\Temp\PRE1.tmp.XML ErrorCode: 2(0x2). Which is effectively saying that ServerManagerCmd is not found. It isn't on my machine as it is deprecated and replaced by Powershell functions, but is on Server 2008 R2. I've tried copying that over and it just fails to run. Is there a way to get Office WebApps installed on Win7 ? Is there a way to get a working version of ServerManagerCmd.exe on a Windows 7 x64 environment ? Many thanks

• Sharing folders with VirtualBox, Win7 Host and Ubuntu 9.10 Guest

  - by unknown (google)

  I have a development setup from this tutorial: http://www.sitepoint.com/blogs/2009/10/27/build-your-own-dev-server-with-virtualbox/ But what I can't figure out is how to share a folder on my Ubuntu virtualized machine with the host Win7. I want to use a Windows text editor to edit code that's on my Ubuntu server. I've tried using the Shared Folders setting, adding "/var/www" but it says that the path is not absolute. When I click on "other", it only allows me to browse folders on my Win7 host. Both the host and guest are 64-bit OS. Thanks in advance!

• nomachine NX: Text missing on all gtk interface (Unity and Gnome Classic)

  - by hansioux

  [Edit] I later realized my issue only occurs when I am using NX to remote access my machine. Therefore I edited the title and description. I have also found the temp solution, which is to "disable render extension" in the custom display settings. But doing so makes the NX experience very slow laggy, and not that nice to look at. [/EDIT] I did a fresh install on a new computer, and was trying to setup my fonts. When I log in remotely via NX, my the text are missing on all gtk based interfaces. That means most menues (except for unity), right click menues, applications themselves, terminal, and so on. About the only thing unaffected is firefox. all the texts are showing just fine for firefox. So that probably already says something about text permissions. I went to check if my fonts have the correct permissions and they do. I removed my custom settings from /etc/fonts/config.d, and still the texts are missing. There is a work around by using "disable render extension" in the custom display settings. How do I fix this issue permanently?

• Fun Upgrading to .Net 4.0

  - by Sam Abraham

  We are currently in the process of upgrading one of our applications to .Net 4.0. Aside from us geeks wanting to always use latest and greatest technologies, an immediate business need for Silverlight 4.0 features justified our upgrade endeavor. The following is a summary of some issues we ran into with our web project:   For security purposes, the IIS 7 .Net 4.0 ISAPI filter is disabled. “Allow” it from the ISAPI and CGI Restrictions screen as shown:   Figure 1 - Allowing ASP.Net 4.0 ISAPI Filter   By default the Web Setup Project only requires the .Net Framework 4 Client Profile to be installed on target system, which offers a lighter weight install for client machines consuming .Net 4.0 applications. However, using certain .Net 4.0 features requires the full .Net 4.0 Framework as outlined in this link: http://msdn.microsoft.com/en-us/library/cc656912.aspx. We hence needed to update the installer to require the complete .Net 4.0 Framework on the target machine and to prompt for its installation if needed.   To accomplish this goal, we updated the installer’s launch conditions to check for .Net 4.0 as well as the installer prerequisites as shown:     Figure 2- Ensure Web Setup Project runs on full .Net 4.0 version Figure 3 - Launch Conditions screen Figure 4 - Set launch condition to .Net 4.0.

• Keeping rackspace vserver alive

  - by mit

  It appears to me that rackspace somehow freezes cloud VMs after some idle time. This means the first page request to a php page takes much longer to respond than the subsequent requests. I am actually querying a machine with wget from a different host now to keep it "alive". But I wonder what frequency would be necessary. Does anyone know the time period after which they send a VM to "sleep"? I guess it would be some minutes. EDIT: There is no caching involved on the php site. It just recently moved from another vhost and there was never such latency on the first request.

• Just installed 13.04 and everything is fine except I cannot connect to the internet. Any thoughts?

  - by razorccatu

  I just installed Ubuntu 13.04 on my HP G62 laptop and the install went smoothly. I did the install off of a USB drive after trying ubuntu. While I was testing it, I connected to my Wireless with out issue and surfed a little. After the install, no wireless. I can still connect to my wireless network (at least it tells me I'm connected at full strength) but No servers can be found. I attempted to ping Google to no avail and I attempted to ping my router to no avail. I tried to then hard wire the machine and once again it told me that I was connected but I was not. When I ran dmesg, I got the following message: Warning: nss-myhostname is not installed. Changing the local hostname might make it unresolvabe. Please install nss-hostname! Is the hostname the issue? if so, how do I resolve it with out internet connection? If it's not the issue, how do I move forward? Thanks for any help. EDIT. I forgot to attach the image of my ifconfig if that might help.

• Windows 7 Not Booting After Moving Partition

  - by Guillermo Phillips

  I have a Sony Vaio laptop. After using GParted to move the primary Windows partion, the laptop no longer boots, saying 'Operating system not found'. I don't have a recovery disc and the only other machine I have access to is a Mac Mini. I have tried creating a bootable USB using the recovery ISO from Microsoft. I can see all the files on the USB stick from my Mac. I followed the instructions here: http://borgstrom.ca/2010/10/14/os-x-bootable-usb.html I have set the laptop BIOS boot order to be 'External' first, but the laptop refuses to boot from the USB stick. I have previously been able to boot from a linux installation on the USB stick. Any help or ideas would be appreciated.

• Azure Linux Virtual Machines Price per Hour, Computation or Running?

  - by Arjun Bajaj

  first of all, I couldn't find a StackExchange site on Cloud Computing. I think this is the most appropriate site, because some of you might be using Azure. So I just wanted to know: The Windows Azure Pricing Page shows Linux Virtual Machine Price as $0.013/hr for an extra small VM. The monthly price comes up to about $10. Is this price charged as number of hours of computation done on the VM or number of hours of running the VM? And if I shutdown the VM, will I be charged anything?

• Windows 2003 - logging off the Administrator account makes web applications inaccessible

  - by Saravana

  Consider a web application installed on a Windows Server 2003 SP2 machine with the admin account. The application is accessible in the server as well as in the network when at least one session of the admin account is logged in. If there are no active sessions of the admin account, the web application is not accessible via the network, nor accessible locally when logged in with another user account. What would cause the web application to be inaccessible there's no Administrator session? Please suggest anything that might help find the solution.

• Can a 32-bit RHEL4 userland work with a 64-bit kernel?

  - by James

  Is there a way to change an i386 RHEL4 machine to run an amd64 kernel, but ensure that it still builds software into same i386 binaries? On Debian this seems quite straightforward: just install an amd64 kernel (worst case, build one like this guy: http://www.debian-administration.org/users/jonesy/weblog/1) and prefix everything with "linux32". Then everything that considers uname -m will be unchanged, I just need to handle the few cases that consider uname -r. What is the Red Hat equivalent? Is the only way a full 64-bit installation on another disk and then chrooting back to the 32-bit system before anyone builds anything? (Even the best examples of that seem to be Debian-based.) Background: We make a large system that runs on (a variant of) i386 RHEL4. However, some of the larger RHEL build machines now have enough RAM that they might benefit from going 64-bit (for the kernel and maybe some of the bigger build steps). Our build system doesn't support cross-compilation.

• Nginx/FPM/PHP all php files say 'File not found.'

  - by Boon

  i just installed nginx 1.1.13 and php 5.4.0 on a centos 5.8 final 64bit machine. Nginx and PHP/Fpm are running, and I can run php scripts via ssh command line, but in the browser I keep getting 'File not found.' errors on all my PHP files. This is how I have my nginx.conf handle PHP scripts: location ~ \.php$ { root /opt/nginx/html; fastcgi_pass unix:/tmp/fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /opt/nginx/html$fastcgi_script_name; include fastcgi_params; } This is a direct copy/paste from my other servers, where it works fine with this setup (but they run older versions of php/fpm). Why am I getting those errors?

• cpufreq-selector, cpufreq-info reporting wrong max speed

  - by dty

  Hi, I've just built a new machine with a Core i5-760 CPU. Max speed is 2.80GHz (turbo mode notwithstanding). I've also done a vanilla install of Ubuntu 10.10. I've added the cpufreq-selector applet to the top panel, and its menus only allow me to select up to 2.39GHz. If I select the "performance" governor, it also shows 2.39GHz. cpufreq-info reports: $ cpufreq-info cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to [email protected], please. analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 1 2 3 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us. hardware limits: 1.20 GHz - 2.39 GHz available frequency steps: 2.39 GHz, 2.26 GHz, 2.13 GHz, 2.00 GHz, 1.86 GHz, 1.73 GHz, 1.60 GHz, 1.46 GHz, 1.33 GHz, 1.20 GHz available cpufreq governors: conservative, ondemand, userspace, powersave, performance current policy: frequency should be within 1.20 GHz and 2.39 GHz.

And ideally to report the actual speed when running in turbo mode too, but that's not critical. Edit: I should probably add that the BIOS (& Windows) are quite happy that it's a 2.80GHz CPU. Thanks.

• How to automatically execute a shell script when logging into Ubuntu

  - by Mike Rowave

  How do I get a script to execute automatically when I log in? Not when the machine starts up, and not for all users, but only when I (or any specific user with the script) login via the GNOME UI. From reading elsewhere I thought it was .bash_profile in my home directory, but for me it has no effect. When I manually execute it in a terminal window by typing ~/.bash_profile it works, but it won't run automatically when I log in. I'm running Ubuntu 11.04. The file permission on my .bash_profile is -rwx------. No .bash_profile existed in my home directory before I created it today. I seem to remember older versions of Linux having a .profile file for each user, but that doesn't work either. How is it done? Do I need to configure something else to get the .bash_profile to work? Or does the per-user login script need to be in some other file?

• Drupal + Lighttpd: enabling clean urls (rewriting)

  - by Patrick

  I'm emulating Ubuntu on my mac, and I use it as a server. I've installed lighttpd + Drupal and the following configuration section requires a domain name in order to make clean urls to work. Since I'm using a local server I don't have a domain name and I was wondering how to make it work given the fact the ip of the local machine is usually changing. thanks $HTTP["host"] =~ "(^|\.)mywebsite\.com" { server.document-root = "/var/www/sites/mywebsite" server.errorlog = "/var/log/lighttpd/mywebsite/error.log" server.name = "mywebsite.com" accesslog.filename = "/var/log/lighttpd/mywebsite/access.log" include_shell "./drupal-lua-conf.sh mywebsite.com" url.access-deny += ( "~", ".inc", ".engine", ".install", ".info", ".module", ".sh", "sql", ".theme", ".tpl.php", ".xtmpl", "Entries", "Repository", "Root" ) # "Fix" for Drupal SA-2006-006, requires lighttpd 1.4.13 or above # Only serve .php files of the drupal base directory $HTTP["url"] =~ "^/.*/.*\.php$" { fastcgi.server = () url.access-deny = ("") } magnet.attract-physical-path-to = ("/etc/lighttpd/drupal-lua-scripts/p-.lua") }
