  • I need a relatively cheap host, which will be able to handle sudden peaks in traffic?

    - by Morten K
    Hello, We're launching a product in a few months, which will obviously have a website. Judging from our current traffic, we believe that overall traffic will probably not be that much, but we are aiming at promoting the site heavily using social media. This has the typical problem, that IF we get suddenly get picked up by a large tech blog, we will see a sudden burst: A very heavy increase in traffic all of the sudden. If we use a cheap charlie host as our current host is (www.unoeuro.com) or something similar like GoDaddy, I'm afraid that the site will go down under the load. If that happens, then we might as well have thrown our social media marketing dollars out of the window. Our site will be relatively lightweight, all videos hosted at Youtube or Vimeo and other than that mainly just a standard webpage (ie nothing too heavy). I am hoping for recommendations for a good hosting company, which has some form of scalable hosting, so if / when a traffic surge hits, the site will not go down.

  • Creating a chain of certificates

    - by StackedCrooked
    This question is a follow up to my previous question, which was, in retrospect, not completely answered: http://superuser.com/questions/126121/how-to-create-my-own-certificate-chain. I'll represent my certificate chain like this: ROOT - A - B - C - ... I am now able to create the ROOT and A certificates, but I didn't succeed in continueing the chain. My command for creating the root certificate is: openssl req -new -newkey rsa:1024 -nodes -out ca.csr -keyout ca.key openssl x509 -trustout -signkey ca.key -days 365 -req -in ca.csr -out ca.pem Certificate A: openssl genrsa -out client.key 1024 openssl req -new -key client.key -out client.csr openssl ca -in client.csr -out client.cer This command depends on the root certificate implicitly using the data found in the openssl config file. Certificate B will only rely on A, so the previous command won't work here. How can I complete the chain?

  • non-GUI connection to local Hyper-V VM without network

    - by sandro
    I have a virtual machine on Hyper-V manager (Windows 2008 R2) without a network configured on the VM. From a powershell script running on the host Windows server, I would like to query into the OS of that local VM for certain information (i.e. if a given process has finished completion). I am using codeplex's pshyperv module (https://pshyperv.codeplex.com/) to interact with Hyper-V manager, but the only cmdlet to connect to the vm is 'New-VMConnectSession', which launches a 'vmconnect.exe' connection to the VM. Since vmconnect.exe is essentially RDP, this is not very script-friendly. From within a host's powershell script, is there any way to send a command to a local virtual machine's OS and receive output, if no network is configured on the VM? (I believe Vmware's 'vmrun' utility has this capability) Another way to ask this question: Does Hyper-V have a non-GUI-based form of vmconnect.exe? (PS. Not sure if this was more stackoverflow or serverfault)

  • can't add sharepoint users from trusted domain

    - by user22215
    I have a very strange problem with our Sharepoint 2007 implementation. I went in today to grant access to a user and was greeted with "The user does not exist or is not unique." Let me start off by saying that this user is not on our domain we have a 2 way trust connecting to one of our subsidiaries. I can see the users in the people pick but can't add them into Sharepoint. This problem flared up after we had some trust issues last two days ago. So I must ask has anyone came across this error and if so what steps did you take to resolve it? This link further highlights my problem: http://social.technet.microsoft.com/forums/en-US/sharepointgeneral/thread/41265a91-191c-4952-9c8c-1e0129b9fd3a

  • My control key doesn't work, how do I fix it??

    - by Blaine LaFreniere
    My control key on the right doesn't work how it should. E.g. Right ctrl + T won't open new tabs in firefox, right ctrl + w won't switch windows in vim, etc. I know the key isn't physically broken, because xev shows that the right ctrl key generates events, but it just isn't responding as I expect it to in applications. Screenshot: http://i46.tinypic.com/33w1h76.png I tried Kim's answer but it still doesn't work. blaine@blaine-laptop ~ $ xmodmap -pke | grep 105 keycode 105 = Control_R Control_R Control_R Control_R Control_R Tried to map as Control_L as well, didn't work. The computer is a laptop, I am unable to plug the keyboard in to another computer.

  • Why times elapsed connecting to a server are different?

    - by user1634619
    I have a small program which connects to a server of my choice and measures the time elapsed to do so. Each time I run it it returns different result. My question is what does this time depend on ? Network congestion for one. If I choose a server that has multiple addresses e.g. google.com the length of physical link may differ from time to time ? Is it safe to assume that it also affects connection time ? Are there any other factors in place ?

  • Set up ad hoc wireless connection between Windows Vista and Mac OS X

    - by Skarab
    I have the following problem - Windows Vista does not connect to adhoc wireless network created on my Macbook. I have tried to create secured (with 40 bit key) and unsecured network but Windows Vista still has problems to connect. Windows VISTA informs me -- after 5 minutes of attempts - that setting up the connection -- with my adhoc network -- took too much time. My question: do I need to configure some settings on Vista to connect it to my Macbook? Maybe it is a problem with DHCP? Edited: I have tried the other way: http://superuser.com/questions/202890/set-up-an-adhoc-network-in-windows-vista-to-connect-to-and-share-the-internet-con

  • esxi 5.1 - copy paste host config doesn't work?

    - by w--
    I followed these instructions for esxi 5.1 to enable copy paste from the host config. (search for "To enable this option for all the virtual machines in the ESX/ESXi host:") http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1026437 But copy and paste doesn't work for new VMs or existing VMs. Did I do something wrong somewhere? I've rebooted VMs and even rebooted host. I can confirm that if I do a per VM configuration, it works. Just not a central host config. Here is a screenshot of my /etc/vmware/config file

  • pip install very slow through virtual box

    - by AJP
    pip install --exists-action=w -r requirements.txt is very very slow through virtual box. Any suggests of how to diagnose and fix? Would seeing the VagrantFile be useful? VirtualBox 4.2.12 (can't upgrade to .14 as it doesn't work.) Vagrant 1.0.7 Host machine: ProductName: Mac OS X ProductVersion: 10.7.5 BuildVersion: 11G63b VagrantFile contains: Vagrant::Config.run do |config| config.vm.box = "precise64" config.vm.customize ["modifyvm", :id, "--memory", 2048] config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.network :hostonly, "33.33.33.21" config.vm.forward_port 5000, 5000 config.vm.forward_port 5555, 5555 config.vm.share_folder "v-root", "/vagrant", "./" Vagrant::Config.run do |config| config.vm.provision :shell, :inline => "VENV=/usr/local/venv bash /vagrant/setup_env.sh" end end Normal download speed is only about 5 times slower at 0.8 Mb per second versus 4 MB per second (as judged by curling a 50 Mb file from S3). But pip install is taking about 20 times longer from Mac (i.e. about 40 minutes) versus 2.

  • Exim4 Disable local delivery?

    - by Robert Ross
    Hey all, I'm running exim4 as my MTA and it works great to send emails to outside emails other than my hostname. When I send an email to my gmail via command line (sendmail forgedtuts@gmail.com, etc...) it works fine. When I send an email to my website's domain, which is also the hostname for the server, i'm assuming it just does local delivery... which won't work because my email is received by another server (Google Apps). So how do I disable local delivery in Exim4? dpkg-reconfigure exim4-config did not give any real results.

  • iMessage program for Windows or similar?

    - by Gabe
    iMessage (desktop app) is only for OS X and it's not clear if they'll bring it to Windows. I'd like to send text messages or iMessage texts using my computer. I have an iPhone iOS 5, jailbroken. I came across this article which allows you to send text messages using the same phone number as your cell phone (this is key) through your computer, but it's only for Android. http://howto.cnet.com/8301-11310_39-57458789-285/send-texts-from-your-computer-with-mightytext/?tag=rb_content;main Also found this question searching on SU but again only for Android. How do I send SMSes from my computer through an Android phone? Windows 7

  • MongoDB on FreeBSD

    - by Hartator
    We are currently using MongoDB 2.0.0 on MacOS but our servers are running FreeBSD. The most recent port of MongoDB is the 1.8.3 version. I have tried to compile the 2.0.0 by hand but I came across errors that I didn't manage to fix. I came across on the Internet a few old resources which are saying that MongoDB does not run well on FreeBSD mainly for performance issue (memory mapped files). Is that true ? Does it mean we have to switch our server to another OS ? Thanks for your opinions! Sources : http://groups.google.com/group/mongodb-user/browse_thread/thread/8131b7e5a5c710d9 http://ivoras.net/blog/tree/2009-11-05.a-short-time-with-mongodb.html

  • In Zabbix how to separate data of the same type but from different sources?

    - by Jader Dias
    I have a machine that receives data from multiple sources. This machine forwards the data to the Zabbix Trapper. I want to be able to view this data separately. One way of doing that is to send data from each source with a different fake hostname. But this is not ideal. I can receive this data in more than one host. I would like to be able to see data from source 1 on host A separately from source 2 on host A and from source 1 in host B. Also posted on: http://www.zabbix.com/forum/showthread.php?t=16503

  • Accessing the Internet via browser

    - by ucas
    I am on Windows 7 and using Firefox browser. I am using WiFi, but since the morning I cannot access the Internet via the browsers (Firefox, Chrome, or IE). The laptop shows there is Internet connection, Skype is online, but I can't reach the Internet. Then I launched Tor application which creates secure channel and provides its Firefox browser. Well, I can now access the Internet over that browser. So, what might be the problem causing this malfunction? The error: The connection has timed out The server at mail.google.com is taking too long to respond. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

  • Make a file non-deletable in USB

    - by MegaNairda
    Somebody used my USB drive and upon returning it to me, I found a autorun.inf that is undeletable. I tried changing it's file attribute which is only H (not even set as a system file) but it keeps on saying Access Denied. The USB is set on FAT32, upon asking my friend, he told me that he uses Panda USB Vaccine http://research.pandasecurity.com/Panda-USB-and-AutoRun-Vaccine/ How do they do this? Im trying to use some Disk Sector editor but have no idea which hex file they change to make this kind of file and make it deletable again. Formatting the drive removes it, but I'm curious as to how to be able to set those kind of file attribute.

  • How to test KVM guest CPU maximum allocation limit?

    - by Ace
    Running Ubuntu 13.04 Host and vm Guest. Using virtio for hdd, nic. Max-allocaion CPU cores is 6, minimum is 2. Ive made a vm with virt-manager just to play with, and to test out kvm. Alright, I have a decent understand how the memory balloon driver works, but I still dont know how to test if the guest OS can utilize the max setting for cpu cores. From what i gather, the host will start one thread of qemu for each core allocated per vm. When i run htop inside the guest, it only shows two cores. (also here is the output of cat /proc/cpuinfo: https://gist.github.com/anonymous/93a361545130923537da ) How can I "force" the guest to allocate the other 4 cores so that it can show 6 cores in htop? Is there a way to do this?

  • SQL Server Management Studio Connect to Server List Editing

    - by Paul Farry
    I'm using SQLServer Management Studio (2005) and I have a fairly lengthy list of servers in there, and I'd like to get rid of some of them that are no longer in use, without having to set them all up again. I know that the C:\Users\*\AppData\Roaming\Microsoft\Microsoft SQL Server\90\Tools\Shell\mru.dat can be deleted and this will remove ALL the entries, but is there anyway to just delete some of them? (Coding info) I looked at the file and it is a serialised blob from the Microsoft.SqlServer.Express.ConnectionDlg.dll (Class Personalization) in the Appplication directory, but all the methods are private. So I can't just create an instance of this and then call Remove on the entries. Update I have written an Article on CodeProject explaining How this can be achieved. http://www.codeproject.com/KB/vb/AlterSQL2005MRU.aspx

  • Speeding up remote X sessions

    - by Alexander Gladysh
    I have a remote machine running Ubuntu 11.10 Server, to which I connect via SSH from OS X 10.7.3: Host remote.example.com ForwardX11 yes ForwardX11Trusted yes Sometimes I want to launch a GUI application there (most notably, gitk). But UI is rather slow. Both remote machine and my own Mac have good internet connection. Ping between them is about 55ms, and there is no packet loss. Is there something I can do to speed things up? Setting up some other remote desktop solution is an option, but I'd like to avoid it since I don't need this application very often.

  • Is a matching entry in /etc/hosts required for hostname?

    - by JohnWoltman
    I was installing a Tomcat webapp that refused to work until I stumbled on someone else's issue with an unrelated product. The solution was to add the machine's name to /etc/hosts, to match the name returned by hostname. Is this required for general Linux networking to function correctly? My webapp is running in a virtual machine so that I can test the webapp, and I don't normally bother with the /etc/hosts file on VMs. I just shook my fist and cursed Tomcat and webapp's behavior. I read http://serverfault.com/questions/118823, but that doesn't say if it's required or not.

  • Sftp via shell - how it is possible

    - by Tomasz Zielinski
    (Moved from StackOverflow: http://stackoverflow.com/questions/4589725/sftp-via-shell-how-it-is-possible) How is it possible for tools like http://mysecureshell.sourceforge.net/ to provide SFTP access by merely specifying them as shell by typing: usermod -s /bin/MySecureShell myuser ? I'm on Debian Lenny, with default sshd/OpenSSH. Is this e.g. a feature of SSH protocol that allows user shell to handle sftp commands? I can't wrap my head around this because usually OpenSSH needs sftp-server module (or the internal one in newer versions) - and this makes me think that sftp commands don't even hit the shell and are handled earlier or by different code path..

  • Logrotate, is this a proper config for what I want to do?

    - by Felthragar
    I started using logrotate a few days ago on a new server setup (actually three of them). My config is as follows. /var/www/mywebsite.com/logs/*.log { rotate 14 daily dateext compress delaycompress sharedscripts postrotate /usr/sbin/apache2ctl graceful > /dev/null endscript } Problem is that this is putting several days of logs into the same file. For example, I've currently got a file called access.log-20121005 which has logs for Oct 3rd, Oct 4th and Oct 5th in it. Is that proper behaviour? What I want for it to do is to create one logfile for each day and keep 14 days of logs. Any help appreciated, thanks.

  • Automatically detect faces in a picture

    - by abel
    At my work place, passport sized photographs are scanned together, then cut up into individual pictures and saved with unique file numbers. Currently we use Paint.net to manually select, cut and save the pictures. I have seen Sony's Cybershot Camera has face detection. Google also gives me something about iphoto when searching for face detection. Picasa has facedetection too. Are there any ways to autodetect the faces in a document, which would improve productivity at my workplace by reducing the time needed to cut up individual images. Sample Scanned Document(A real document has 5 rows of 4 images each=20 pics): (from: http://www.memorykeeperphoto.com/images/passport_photo.jpg, fairuse) For eg. In Picasa 3.8, On clicking View People, all the faces are shown and I am asked to name them, can I save these individual pictures automatically with the names as different pictures.
