• Solution for file store needing large number of simultaneous connections

  - by Tennyson H

  So I'm fairly new to large-scale architectures. We're currently using linode instances for our project, but we're brainstorming about scaling. We need a file store system than can deliver ~50mb folders (user data) to our computing instances in a reasonable amount of time (<20 sec), and scale to 10000+ total users, and perhaps 100+ simultaneous transfers. We are also unsure whether to network mount (sshfs/nfs) or just do a full transfer store-instance at the beginning and rsync instance- store at the end. I've experimented with SSH-FS between our little Linode instances but it seems to be bottlenecked at 15mb/s total bandwith, which wouldn't do under 10+ transfer stress let alone scale v. large. I also tried to investigate NFS but couldn't get it working but have little hope that it'll do within our linode network. Are there tools on other cloud providers that match our needs? Should we be mounting, or should we be transferring? Thanks very much!

• Does Microsoft offer a corporate IM/collaboration tool similar to Campfire? My googlefu skills appear to be failing me today.

  - by user54266

  I mentioned to my boss that we should look into a single unified IM client that we could use and secure on a corporate level, and then suggested Campfire. We're a primarily Microsoft house so he suggested we use something that would better integrate with SharePoint and the other tools our end users use in house. However, I'm not aware of any Microsoft tool that does something like this. Obviously there is MSN Messenger but I think/hope he wasn't referring to that. Other than a product from 2005 I haven't been able to locate a Microsoft corporate IM tool...does anybody know what he may have been talking about?

• Win xp reinstall now I am unable to connect to broadband what shall I select to do this?

  - by waterfallrain

  Hello, My hardrive was failing so I needed to reinstall win xp. I completed the reinstall and the drivers but now only the wireless connection works. The broadband states connected but does not go out to the interenet. When I click Internet Explorer it says unable to find webpage. I have tried several major sites so I know its not the site but some configuration or something I need to do on my end. When I go to the cmd prompt and renew the ip it refers to my wireless nothing about this broadband connection. What do I type/select to get this to go out to the Internet. The broadband is working for my other laptop so I know the connection is not the issue. Any help would be much appreciated thank you.

• Native Symlink Windows 2008 r2 with cygwin

  - by mickdelaney

  Is it possible for me to create an ssh session on windows which then does some folder/file manipulation and then creates a NATIVE windows symlink. i.e. a symlink that will be recognised by IIS and other app/services. i've tried to create a symlink to a folder but all i get is a 1kb system file (with the same name) where the symlinked folder should be. using ln -s SOURCE TARGET i end up with target (system file, 1kb). BUT in cygwin i can see the symlinked folder as normal. Spent too much time on this :-)

• Remote desktop into a linux machine, is this possible?

  - by fire

  I have a VPS by my host running on a linux server, and they have given me SSH access. Is it possible to remote desktop into the server, like you can on Windows, so that I can physcially click on things rather than having to use SSH commands? Surely this must be running on Fedora or Ubuntu etc. so there is some type of OS. You would probably have to install something on the servers end I suppose but just want to know if its possible and what the options are. And before you say "why not ask your host" I find superuser responses are usually much quicker :-)

• .htaccess rules not working, but the file seems to be loaded

  - by user221877

  I am trying to remove .php at the end of the URL from any page thats loaded. RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}.php -f RewriteRule ^(.*)$ $1.php Its running on my own server, which has WHM/cPanel, so I can change settings at the server level, I'm just not really sure what I'm looking for. I found the httpd.conf file, but it said it was auto generated by whm, so I tried looking in whm for the correct settings but it had barely any settings related to htaccess. If I fill htaccess with gibberish it stops the site from loading, which I assume means that the .htaccess file is being loaded, so I'm not sure what the issue is.

• Emacs equivalent of this Vim command to run my tests?

  - by eightbitraptor

  I'm using Emacs at the moment and experimenting with it for my Rails development and there is one thing that I do quite regularly in Vim and I'd like to know if an equivalent exists in Emacs, or an alternative workflow to achieve the behavior that I need. The command in Vim is :map ;t :!rspec --no-color %<cr> Essentially this maps a key combination to run a bash/shell command on the file represented by the current buffer (% expands to the filename at runtime, the <cr> is just a carriage return at the end to execute the command). I map all sorts of random little commands as and when I need them and I really miss the immediacy of this approach. How can I achieve something similar?

• Can someone please explain these Network Activity entries are? (resource monitor windows 7)

  - by Keyes

  The first one is the address microsoftword.com.br. What is this? I noticed when I connected windows to the internet briefly, and it went away soon after. when I typed the address into my tablet, it redirected to bing with the search "microsoftword com" with MSSRPD at the end of the address. The other unknowns seemed to appear when my brothers laptop was connected to the network. Is that normal? Usually if I disconnected and reconnected they would appear, but I noticed when I had disconnected and reconnected to try it didn't happen as he wasn't connected. I'm concerned about the microsoftword one is. Is it legitimate? The svchost that associated with is a legit svchost image.

• Include new rows in autofilter range

  - by user9645

  I am working with an excel 2007 worksheet that has the "filter" applied so that each column heading has a pull-down menu for sorting. When I add new rows to the end of the table by cut-n-paste from the last row, these new rows are not included in the sorting. I can't seem to get the newly added rows to be included in the filter range. I tried un-selecting and re-selecting the "filter" button and also tried the "reapply" button. The "clear" button is always greyed out. I can't seem to find any relevant help for this online anywhere. Not sure if it matters, but the heading row and the first column are set to be "sticky" (they don't scroll with the rest of the table.)

• Should I create a second WAN Interface for a new SSLVPN setup on my Sonicwall 2400?

  - by TheSuperman

  Sonic Wall 2400 I'm setting up a new SSLVPN on our Sonicwall, very new to this. I currently have an exchange server as well, so mail.company.com is directed to our mail server. I'd like to setup a clean link for my low end users, remote.company.com to be for the SSLVPN, but I'm not sure how to do this within the Sonicwall? I setup SSLVPN on port 443. Only 1 WAN setup, on the X1 Interface. We have an A record setup with the same static IP used on the WAN Interface, and is configured for mail.company.com. Should I use a new static IP from our block of usable IP's to create the new Remote.Company.com? If so, I have no idea where to start on this on the Sonicwall? Any suggestions?

• Color in Cygwin terminal

  - by ForbesLindesay

  I've installed cygwin because I'm a bit fed up with the Windows terminal not being great. The only problem I'm having is the lack of colours. You can see the problem in the following 2 screenshots that display the same command: All I want is something which has a nice font, resizes properly (including proper behaviour when maximised) and support for colours. Ideally I'd like tabs too. This seems like a silly reason to end up buying a mac, so I'm hoping I can get all these things on windows somehow.

• Windows 8 Update on Bootcamp

  - by RazorSharp

  I currently have Windows 8 Consumer Preview installed on a Mac Bootcamp Partition. Microsoft recently released the Windows 8 Release Preview, and I'd like to upgrade, but I'm worried that upgrading to the Release Preview (while in the Windows 8 partition) will erase my other partitions (ex. the Mac OS X partition). By upgrading from Consumer to Release (using the installer on Microsoft's website) while IN the Windows 8 partition, will it end up re-formating the whole hard drive / erasing partitions / removing Mac OS X? Are there any 100% positive answers out there? Will this work, and if not then how would you suggest updating? Note: I have a Time Machine backup of my Mac, but it isn't the WHOLE Mac.

• How do brand laptop manufacturers restrict hard disk drive?

  - by user176705

  I'm curious to know, when I bought a brand new laptop there are limitations to create or change the HDD partitions, except the following partitions: c:\ drive (Main partition + OS drive) NTFS. 400 Gb. Recovery drive NTFS. 15 Gb. Tools drive FAT32. 2 Gb. System drive NTFS. 0.3 Gb. My questions are: How do manufacturers restrict HDDs ? What is the term for these restrictions? Can this be applied to desktop PCs? Is it possible to modify the restrictions by an end-user?

• Ubuntu upstart hangs on interactive start & stop

  - by danorton

  How do I get Ubuntu upstart to not hang on interactive start & stop? I have created many upstart scripts that work fine during init, but often hang when I enter them at the console. If I CTRL+C out, all that happens is that the job changes state. The script is never run. I’m running Ubuntu Lucid on a Xen virtual server with a Linux 2.6.39 kernel. Below is merely a representative example of many scripts that behave this way: description "apache2" start on local-filesystems \ and (net-device-up IFACE=lo) \ and (runlevel [2345]) stop on runlevel [016] respawn respawn limit 10 5 expect daemon script . /etc/apache2/envvars /usr/sbin/apache2ctl start end script

• Dumb Terminals, Virtual Desktop

  - by user67714

  I need some help in setting up a dumb-terminal type concept for Windows machines. We have a computer lab with 40 computers, all of them are ageing. Unfortunately, we don't have enough funds to get all of them replaced. On the other side, we have very powerful rack servers which are quite underutilized. I was thinking of a solution which would enable those lab computers to use the rack servers. Remote desktop is an option, but I wanted something that is more transparent to the end user. Are there any free or low cost solutions for such an scenario?? Thanks

• How can I push a git repository to a folder over SSH?

  - by Rich

  I have a folder called my-project inside which I've done git init, git commit -a, etc. Now I want to push it to an empty folder at /mnt/foo/bar on a remote server. How can I do this? I did try, based on what I'd read: cd my-project git remote add origin ssh://user@host/mnt/foo/bar/my-project.git git push origin master which didn't seem right (I'd assume source would come before destination) and it failed: fatal: '/mnt/boxee/git/midwinter-physiotherapy.git' does not appear to be a git repository fatal: The remote end hung up unexpectedly I'd like this to work such that I don't have to access the remote host and manually init a git repository every time ... do I have to do that? Am I going down the right route at all? Thanks.

• Nagios state transition and event handler issue

  - by Dattatray

  We are using Nagios to check duplicate processes. define service { use local-service host_name xxx service_description xxx Duplicate Processes check_interval 1 max_check_attempts 1 contact_groups admins event_handler restart-dependent-processes check_command check_procs_duplicate!2!3!2!2!2 } check_procs_duplicate checks if there are any duplicate processes and returns the state - e.g. CRITICAL. The event handler kills the duplicate processes and it's dependent processes and starts one instance of the process and dependent process. At the end of this again Nagios checks if there are any duplicate processes and sets the state accordingly - OK/WARNING/CRITICAL. The event handler takes more time to start the processes and during this time if someone manually starts the process, the state will remain in CRITICAL itself. During the next interval, Nagios will again check for duplicate processes and it will find it again CRITICAL. The event handler will not get executed now, as the previos and current both the states are CRITICAL. Any pointers about how to fix this issue?

• What are the pros of switching DNS names with a database server hardware upgrade?

  - by wilbbe01

  When we upgrade to new hardware at work we usually increment a number in the DNS name. For example. We have a server called database-2, that is slated to become database-3 in the coming days. I haven't been able to find a good reason why this is good behavior. To me the work of trying to catch all end user machines, as well as all servers dependent on the database server is far riskier than simply moving the database and ip/name with it to the new hardware. A little over a year ago we spent several months of requests coming in, as infrequent users began using software that needed to be updated to point to a new DNS name. I am struggling to find answers as to why this is a good practice. So the question. Why is using DNS names as a "server hardware version identifier" a good idea? What am I overlooking? Thanks much.

• nagios service check

  - by DRH

  I am new to nagios and we have a small issue I need to ask assistance with. Many of the machines that we monitor can go unresponsive for a bit when some very intensive cpu tasks are run. This makes nagios send warnings and alerts while these hosts are busy reporting things like 'ping timeout' or 'zombie processes' and even swap space warnings, but in actuality there is not a problem. Is there a way to configure nagios to not send such alerts, but check x number of times over a period of time and only then send an alert at the end of that time if the server in question has not recovered?. Looking at the commands.cfg file, I see entries like this: define command{ command_name check_local_swap command_line $USER1$/check_swap -w $ARG1$ -c $ARG2$ } How could I modify this example to accomplish what I want above. Thanks

• Vagrant and cups port forwarding not working. Not accessible

  - by AAlvz

  I'm working with vagrant and I'm trying to use it as a printing server. I installed cups. Internally everything works just fine. I can even make a quick curl to my localhost:631 (cups port inside my vagrant) and there's everything. The thing is I can't access it in any way I try from the host machine. Obviously I forwarded the port and I've tried with several ports. I've also tried with Debian squeeze and Ubuntu 12.04. Here is my current Vagrantfile Vagrant.configure("2") do |config| config.vm.box = "guruDebian" config.vm.network :forwarded_port, guest: 80, host: 8080 config.vm.network :forwarded_port, guest: 631, host: 6363 ## HERE IS CUPS end Any ideas? ... I'll upload any file if necessary.

• Windows 8: How to Lock (not sleep) laptop on lid close?

  - by Eye of Hell

  If my laptop is connected to power source and is not configured to sleep on lid close (it is connected to power source and is working, i don't want it to sleep. It's compiling my code) if i close the lid, laptop will do nothing. This works as expected, but actually if i have my laptop connected to power source in the office it will be good to lock it if i close a lid. So no one can just open the lid and see my unlocked desktop. I searched google and it says thet correct use case is to manually lock laptop via Win + L every time before lid is closed. This is ok, but not very secure - after all, i can forget Win + L. Is t any easy way (maybe some registry value or app) to configure windows laptop so it will lock on lid close even without sleep? Of course i can write app / powershell script for this task, but this is not suitable for non-programmers end users.

• Speed up connection to MySQL

  - by Leonick

  So here's one for you. Any idea on a way to shorten the time it takes to connect to a MySQL database? The reason I'm wondering is because I find that just connecting to the DB adds just over a second to the rendering of the page and that seems a bit long considering Apache and MySQL is running on the same machine and the mysqli_connect is connecting to localhost. It's just such a shame when the connection takes a second while any query I end up doing won't add any significant amount of time to the render/load time. Any ways to shorten the time it takes to open a connection?

• Joining windows LANs through SSH tunnel

  - by Akke

  I have at home a computer (a windows 7 ult machine) I need to use to manage stuff at the office which hosts windows and linux servers. I am able to set up a SSH tunnel (atleast for firefox proxying) and I'd like to be able to access shared windows network drives on the other end too. I heard something about needing some kind of samba service but I couldn't find anything useful by googling that. What do I need in order to make an SSH tunnel to the office (a NAS, running linux) so that I can access windows server 2008 and windows 7 network drives? Bonus: I'd like to be able to access a MSSQL database server too if it's possible.
