  • Insulate hosted client domains from server IP address change?

    - by babtek
    I will be hosting web content for many client domains on a single IP address (with a web hosting company, not inhouse machine). Initially, I must give client some information to configure their registrar to point the domain to my server. I want client domains insulated from a potential IP address change, so if I change hosts/IP address they don't have to reconfigure anything with their registrar. Is this reasonably possible without running my own nameserver? If so, what would be the smartest way to make it happen? Instruct clients to make CNAME record? Use some type of DNS management service that clients would use as a nameserver?

  • How to make a pxe bootable 10MegaByte or larger dos image?

    - by rjt
    Would like to make a "massive" DOS floppy disk image, say 10MegaBytes or more containing all the firmware updates i need for any system, harddrive, BIOS. i do not need the DOS image to be networkable as everything will be on the PXE booted image, but networking would be nice. Since ZipDisks were attached to the floppy disk controller and were over 100MegaBytes, this should be possible. i tried a long time ago to do this and spent too much time on it only to have it fail to boot. So if someone has reliable instructions on how to create such a nightmarish beast and edit it, please let me know. One image that can used for PXE and copied to a USB stick would be a plus. Too bad manufacturers don't supply a single bootable Linux ISO containing all their firmware updates, that would be easy to boot over-the-lan and have networking. HP servers do this and it is awesome.

  • Static error page served by nginx when my application is down

    - by dreeves
    If my (Rails) application is down or undergoing database maintenance or whatever, I'd like to specify at the nginx level to server a static page. So every URL like http://example.com/* should server a static html file, like /var/www/example/foo.html. Trying to specify that in my nginx config is giving me fits and infinite loops and whatnot. I'm trying things like location / { root /var/www/example; index foo.html; rewrite ^/.+$ foo.html; } How would you get every URL on your domain to serve a single static file?

  • on Red Hat Enterprise and CentOS, what is creating /var/run/reboot-required?

    - by EdwardTeach
    On CentOS 5.8+ and Red Hat Enterprise 6+, when installing/updating packages, I notice a flag file /var/run/reboot-required is created when appropriate. On Ubuntu (and Debian too, I'm guessing), if package "update-notifier-common" is installed, a package postinst script triggers creation of this flag file. On RHEL/CentOS I can't figure out how this is happening. For instance, on RHEL and CentOS I recently installed several updates and /var/run/reboot-required was created. One of them was an "openssl" package upgrade. I assume this was what created the flag file, since on Ubuntu it also works this way. However I looked at all "rpm -q --scripts" for each updated package, and didn't see anything that was likely to have created that flag file. Mostly I saw "postinstall program: /sbin/ldconfig". So my questions are: What creates this flag file on RHEL/CentOS? Does it require a special package to be installed, analogous to the "update-notifier-common" package on Ubuntu?

  • Laptop wakes from sleep, once, due to audio controller (Windows 7)

    - by stijn
    The laptop is a recent Dell XPS 15z and the problem is as follows (reproducible about 90% of tries): put laptop to sleep using either Start-Sleep or closing the lid laptop goes to sleep after about 5 seconds, but instantly wakes again showing a black screen (touching the keyboard or moving the mouse shows the login screen one normally gets after wake) login again, put laptop to sleep latop stays in sleep mode output of powercfg -lastwake after the first instant wake shows the audio controller is responsible. Why would that be, why only the first try, and how to fix this?

  • Photo/Video gallery for Ubuntu web server

    - by Andrew
    I'm trying to have a gallery that can display images as well as videos for visitors to my web server. I'm running Ubuntu 12.10, and have Apache installed. All my images and videos are in /var/www/media. I've taken a look at bbgallery, which is simple enough for me, but I don't think it supports video. I've also looked at Single File PHP Gallery, but it doesn't support video. Does anyone know of a gallery that supports video as well, which I can use for my web server? EDIT: I do not have a database.

  • Mono on Linux: Apache or Nginx

    - by Furism
    Hi, I'm developing an ASP.NET application that will be run under Linux/Mono for various reasons (mostly to stay away from IIS, quite frankly). Of course the first web server I had in mind was Apache. But Apache, for all its advantages, adds a lot of overhead. Also, the application I'm building needs to be highly scalable and performance is one of the main concern. Apache has, obviously, a very good reputation and its record speaks for itself, but I don't need things like Reverse Proxy or Load Balancing because dedicated network devices would be used for that. So those modules from Apache will never be used. So basically my question is: since Nginx seems to fit exactly needs, is there any caveat I should be aware of? For instance, is Nginx renowned to be particularity safe? When security flaws are detected, how fast are they patched? Any insight on the pros and cons of using either of those servers in conjunction with Mono is welcome.

  • VMWare Guest NIC Teaming

    - by Justin Popa
    We're looking to add additional bandwidth to a VM running on an ESXi cluster running 5.1. How can I team these within the VM? I suspect I need to add a second e1000 and then install some Intel software to team them. Any idea which version of Intel driver? Is there some better software to use? EDIT: Sorry, neglected some information. The guest OS is Win2k8R2. The physical NICs on the host are 1Gbps. The reason this has come up is we are seeing the VM hitting near cap on the capability of a single 1Gbps link (Usually at 100-110MBps, bursting to 130s, but I think that may just be a UI math lie) and we're interested in seeing if adding an additional NIC in a teamed setting will increase the overall throughput.

  • Create mix CDs from MP3 files

    - by Dave Jarvis
    How would you write a script (preferably for the Windows commandline) that: Examines thousands of MP3 files stored on a single drive (e.g., G:\) Randomizes the collection Populates a series of directories up to 650MB worth of songs (without exceeding 650MB) Every song is shucked exactly once (Optional) The directory size comes as close as possible to 650MB The DIR, COPY, and XCOPY commands have no explicit file size switches. A few Google searches have come up with: File size condition in DOS Cygwin and UWIN DOS File sizes It would be ideal if UNIX-like environments can be avoided. My question, then: How do you compare file (or directory) sizes using the Windows commandline?

  • git/gitolite: big git repo with several mini projects

    - by Jay
    I'm pretty new to the whole version control thing, and even more so with git. I recently installed git on my computer(s) and set it up on a NAS server. However, I have several client folders with several project folders per client folder. Each one of these client folders is a giant repo, encompassing every project inside it. What I'm wondering is, is there a way to break this apart? So, for instance: The NAS is my 'origin', and has gitolite installed On computer1 I have every project folder in a client folder ever created (clean branch), In computer2 I do not a new checkout of the client branch (because all the projects in that branch are all completed and I don't need a working copy of it), but I do have a brand new project folder for that client "newproject". Is there a way to commit and push to the NAS repo from computer2? Or perhaps is there a better way of organizing all this?

  • MaxClients in apache. How to know the size of my proccess?

    - by Larry
    From http://httpd.apache.org/docs/2.2/misc/perf-tuning.html The single biggest hardware issue affecting webserver performance is RAM. A webserver should never ever have to swap, as swapping increases the latency of each request beyond a point that users consider "fast enough". This causes users to hit stop and reload, further increasing the load. You can, and should, control the MaxClients setting so that your server does not spawn so many children it starts swapping. This procedure for doing this is simple: determine the size of your average Apache process, by looking at your process list via a tool such as top, and divide this into your total available memory, leaving some room for other processes. The main issue is that I can't understand how to know the size, because, well i have the size of httpd on no more of 3888 But, if we need to determine the number for MaxClients, and I have 4GB of RAM, so I get: 972, so I should use like 900 in the MaxClients?

  • Bandwidth Control on our Internet Connection

    - by AlamedaDad
    Hi all, I have Covad dual/bonded T1 service in our office coming through a Cisco 1841 and then through a Sonicwall 3060Pro/Enhanced SW firewall. The problem I'm looking for some input on is how to limit the amount of bandwidth any single user/PC can user for downloading a file from the Internet. It's become an issue that when one person happens to download let's say an ~300MB file, normal internet access for the other employees slows to a crawl. I've seen through MRTG that in fact usage of the circuit jumps to the full 3mb for the duration of the download and then drops. Is it possible to control this? I'm not familiar with QOS or the like so I'm not sure. Any help on this would be appreciated. Thanks...Michael

  • Shell Script Launching Child Processes

    - by Matt James
    Disclaimer: I'm totally new to shell scripting, but have quite a bit of experience in other languages like PHP and Obj-C. I'm writing my first daemon script. Here are the goals: I want it to run in the background I want it to be triggered by an init.d script that includes start/stop/restart commands I want each process in a loop to trigger its own subprocess. When the parent process kicked off by the init.d script is killed, I want the subprocesses to die as well. Essentially, I'm looking for the same kind of behavior that appears to be very common among software like apache, spamd, dovecot, etc. But, based on my research, I haven't found a single, simple answer as to how this kind of thing is achieved. Any help is greatly appreciated.

  • What sort of attack URL is this?

    - by Asker
    I set up a website with my own custom PHP code. It appears that people from places like Ukraine are trying to hack it. They're trying a bunch of odd accesses, seemingly to detect what PHP files I've got. They've discovered that I have PHP files called mail.php and sendmail.php, for instance. They've tried a bunch of GET options like: http://mydomain.com/index.php?do=/user/register/ http://mydomain.com/index.php?app=core&module=global§ion=login http://mydomain.com/index.php?act=Login&CODE=00 I suppose these all pertain to something like LiveJournal? Here's what's odd, and the subject of my question. They're trying this URL: http://mydomain.com?3e3ea140 What kind of website is vulnerable to a 32-bit hex number?

  • How to disable PHP's ini_set for specific configuration options?

    - by Dunedan
    I'm running a setup with PHP 5.3.8 and use php-fpm with it's chroot functionality to separate multiple customers. So each customer has it's own chrooted PHP-environment, which is quite fine. I now want to disallow that a customer can change the *memory_limit* of his PHP-instance by using *ini_set*. On the other hand I don't want to disable *ini_set* completely. So I'm searching for a possibility to disable the possibility to set specific PHP configuration options (like *memory_limit*) via *ini_set*. Does somebody know how to achieve that?

  • Merge only a one remote branch into a local branch with Mercurial

    - by Pepijn
    I wan to manage some profiles as XML files in Mercurial repos. The setup I'm thinking of: Each user has a repo with a branch where he manages his own profile, and a number of branches where he can pull and merge other profiles from that branch of another user. So for example I have my own profile branch and a branch labeled friends, in which I want to pull the profile branches of a few remote repos, to collect like a collection of profiles. I figured out that since the repos are unrelated I need to use -f, but I can't figure out how to pull and merge only a single branch into another. So I want like me friend someone profile ---> friends <--- profile \-> family friends <--- profile Is this even possible? Should I use separate repos instead? Is there a better solution?

  • ubuntu 12.04 copy whole server

    - by Jiechao Li
    all. My company host all the software, including application and website in one local ubuntu server. But recently we start to use Amazon EC2, and want to move the whole server to cloud. Is there anyway to copy the entire server to EC2? OS is the same, ubuntu 12.04, and just one server, and one user account. On EC2 is also one instance, one account. I don't know whether there is a simple and quick way to do that. Thanks a lot!!

  • Wiping out user and/or root password in embedded linux

    - by TryTryAgain
    We have a security camera system running an embedded linux. It boots with Lilo as a bootloader and has no tty access once booted. I don't know any username either. SSH/22 is open, but I don't think brute force is an option. I have tried all the common tricks to reset a linux user password (boot from the bootloader in single user mode = doesn't happen, still prompts for user login, boot to a live cd = can't access the file system...it's all loop files and other binary, etc etc), but they are all not possible as it is an embedded linux setup the way it is. Any help/suggestions would be appreciated. Thanks

  • How to know the root device size of some public AMI?

    - by red23jordan
    Since I do not want to pay money for my testing, the free limit size is 10G. I can know the root device root for some default AMI such as Amazon Linux AMI 2012.03 The Amazon Linux AMI 2012.03 is an EBS-backed, PV-GRUB image. It includes Linux 3.2, AWS tools, and repository access to multiple versions of MySQL, PostgreSQL, Python, Ruby, and Tomcat. Root Device Size: 8 GB And the last row displayed 8GB. However, if I find AMI in Community Page, it does not show the root device size. Can anyone know how to use the instance such as centOS that is not provided by default but it is under 10GB so that I can still free use?

  • What are the benefits of running chef-server instead of chef-solo?

    - by strife25
    I am looking at automated deployment solutions for my team and have been playing with Chef for the past few days. I've been able to get a simple web app up an running from a base Red Hat VM using chef-solo. Our end goal is to use Chef (or another system) to automatically deploy application topologies to the cloud as we run builds. Our process would basically run like so: Our web app code, dependencies, and chef cookbooks are stored in SCM A build is executed and greats a single package for images to acquire and test against The build engine then deploys new cloud images that run a chef client to get packages installed. The images acquire the cookbooks from SCM or the Chef server and install everything to get up and running What are the benefits and/or use cases for getting a Chef Server running? Are there any major benefits to have a Chef Server hold and acquire the cookbooks from SCM vs. using chef-solo and having a script that will pull the cookbooks from SCM?

  • Scripting a database copy from MS Sql 2005 to 2008 without detach/backup/RDP

    - by James Santiago
    My goal is to move a single SQL 2005 database to a seperate 2008 server. The issue is my level of access to both servers. On each I can only access the database and nothing else. I cant create a backup file or detach the database because I don't have access to the file system or to create a proxy. I've tried using the generate script function of sql 2005 management studio express to restore the schema but receive command not supported errors when attempting to execute the sql on the new database. Similarly I tried using EMS SQL Manager 2005 Lite to script a backup of the schema and data but ran into similar problems. How do I go about acomplishing this? I can't seem to find any solutions outside of using the detach and backup functions.

  • HPCM 11.1.2.x - Outline Optimisation for Calculation Performance

    - by Jane Story
    When an HPCM application is first created, it is likely that you will want to carry out some optimisation on the HPCM application’s Essbase outline in order to improve calculation execution times. There are several things that you may wish to consider. Because at least one dense dimension for an application is required to deploy from HPCM to Essbase, “Measures” and “AllocationType”, as the only required dimensions in an HPCM application, are created dense by default. However, for optimisation reasons, you may wish to consider changing this default dense/sparse configuration. In general, calculation scripts in HPCM execute best when they are targeting destinations with one or more dense dimensions. Therefore, consider your largest target stage i.e. the stage with the most assignment destinations and choose that as a dense dimension. When optimising an outline in this way, it is not possible to have a dense dimension in every target stage and so testing with the dense/sparse settings in every stage is the key to finding the best configuration for each individual application. It is not possible to change the dense/sparse setting of individual cloned dimensions from EPMA. When a dimension that is to be repeated in multiple stages, and therefore cloned, is defined in EPMA, every instance of that dimension has the same storage setting. However, such manual changes may not be preserved in all cases. Please see below for full explanation. However, once the application has been deployed from EPMA to HPCM and from HPCM to Essbase, it is possible to make the dense/sparse changes to a cloned dimension directly in Essbase. This can be done by editing the properties of the outline in Essbase Administration Services (EAS) and manually changing the dense/sparse settings of individual dimensions. There are two methods of deployment from HPCM to Essbase from 11.1.2.1. There is a “replace” deploy method and an “update” deploy method: “Replace” will delete the Essbase application and replace it. If this method is chosen, then any changes made directly on the Essbase outline will be lost. If you use the update deploy method (with or without archiving and reloading data), then the Essbase outline, including any manual changes you have made (i.e. changes to dense/sparse settings of the cloned dimensions), will be preserved. Notes If you are using the calculation optimisation technique mentioned in a previous blog to calculate multiple POVs (https://blogs.oracle.com/pa/entry/hpcm_11_1_2_optimising) and you are calculating all members of that POV dimension (e.g. all months in the Period dimension) then you could consider making that dimension dense. Always review Block sizes after all changes! The maximum block size recommended in the Essbase Database Administrator’s Guide is 100k for 32 bit Essbase and 200k for 64 bit Essbase. However, calculations may perform better with a larger than recommended block size provided that sufficient memory is available on the Essbase server. Test different configurations to determine the most optimal solution for your HPCM application. Please note that this blog article covers HPCM outline optimisation only. Additional performance tuning can be achieved by methodically testing database settings i.e data cache, index cache and/or commit block settings. For more information on Essbase tuning best practices, please review these items in the Essbase Database Administrators Guide. For additional information on the commit block setting, please see the previous PA blog article https://blogs.oracle.com/pa/entry/essbase_11_1_2_commit
