  • Are EC2 security group changes effective immediately for running instances?

    - by Jonik
    I have an EC2 instance running, and it belongs to a security group. If I add a new allowed connection to that security group through AWS Management Console, should that change be effective immediately? Or perhaps only after restart of the instance? In my case, I'm trying to allow access to PostgreSQL's default port (tcp 5432 5432 0.0.0.0/0), and I'm not sure if it's the EC2 firewall or PostgreSQL's settings that are refusing the connection.

  • Merely installing PHP5 causes my AWS Ubuntu server to die minutes later from a massive CPU spike

    - by Mark Amery
    I have an AWS server with Ubuntu 11.04 as the OS that is running an Apache2 webserver (incidentally Python-based and using Django). We recently needed to add support for php5 to let us use a third party PHP library (incidentally for serving minified versions of js and css files). However, for no reason any of us can discern, if we simply run sudo apt-get install php5 on the server, then the install appears to finish successfully but, without us taking any further action (including not yet running sudo apt-get install libapache2-mod-php5, which I think would be the next step for us if everything worked), or actually running any PHP scripts on the server, a few minutes later the server becomes impossible to connect to, and looking at the 'Monitoring' tab for the server in the EC2 Management Console reveals that a while after the installation, CPU usage spikes to 100% and stays there permanently (until we reboot the server from the AWS Console). After rebooting, the server also reliably dies within a few (between 0 and 10) minutes. We restored the server to a pre-PHP state from an AMI Image, observed that it was stable, and then tried installing PHP5 again and observed the server die in exactly the same way, so we're pretty much certain that installing PHP5 is what causes the symptoms. What on earth could be causing this behaviour, and how can we get PHP installed on the server without it dying?

  • How to address an EC2 instance from both inside and outside datacenter?

    - by Alexandr Kurilin
    I'm trying to find a good way of being able to address my EC2 database instance from both inside and outside of the datacenter. Other EC2 instances need to be able to call into it, and other clients like pgAdmin might need to connect to it from the outside world as well. It's my understanding that using the internal and external DNS names is sustainable long term as each reboot leads to a change. I'm thinking of associating an Elastic IP with the instance and giving it an A record (say db1.mydomain.com) which I then will use both within and outside the datacenter. Further instances in the same role will get the same treatment and a DNS record of db2.mydomain.com etc. Now, is there a cleaner and more stable way of achieving this result? Am going about this the wrong way? Suggestions?

  • Does AWS resolve same-datacenter hostnames to 10.* addresses for different customer accounts?

    - by Scott Ritchie
    If I bring up two Amazon EC2 instances and run nslookup on one for the other's hostname, amazon will return a 10.* address. This is routable within amazon, and works just fine. But does this work between different accounts? If I use one of my nodes to nslookup a hostname belonging to another customer (but still in the same datacenter) will it resolve as a 10.* address or will it give the standard public IP?

  • Locking down remote desktop using AD GPO

    - by Brettski
    I am currently locking down a companies remote desktop access via a VPN. What I need to do is disable remote printing, file transfer and clipboard via active directory for the workstations that will be accessed. I am having trouble figuring out which GPO's are used to restrict this. My basic approach is to restrict VPN users to port 3389 so the will be able to access their work computers remotely but nothing else (I will look into layer 7 scanning later). With this I want to ensure they are unable to transfer and data via files, printing or the clipboard. The environment is Windows Server 2003

  • Run a script on user connection on the VM host

    - by Scott Chamberlain
    I have a server running a Virtual Desktop Managed Pool, what I would like to do is when a user logs in I would like a script to check the number of available VMs and if below a threashold add additional VMs to the pool. The script to check the load and add to the pool is not the problem, I have that already figured out: $collectionName = "Test1"; $rdvh = "vmHost.example.com"; $minAvailableVMs = 2; Import-Module RemoteDesktop; $pool = Get-VirtualDesktopCollection -CollectionName $collectionName; $availableVMs = $pool.Size - ($pool.Size * $pool.PercentInUse / 100); $status = Get-VirtualDesktopCollectionJobStatus $collectionName #only add new servers if we are below the threashold and in the JOB_COMPLETEED state if($availableVMs -lt $minAvailableVMs -and $status.Status -eq [Microsoft.RemoteDesktopServices.Management.VirtualDesktopCollectionJobStatus]::JOB_COMPLETED) { Add-RDVirtualDesktopToCollection -CollectionName $collectionName -VirtualDesktopAllocation @{"$rdvh" = 1} } The problem I am having is, how do I run the above script on the Virtualization Host/Connection Broker/Some other server when a user connects?. I don't think it would be appropriate to run this as a logon script inside the VM, I think there is a way to do this on the management side but I don't know the new scripting interface in Server 2012 R2 well enough to know which commandlets I should look for to schedule this. EDIT: I know System Center is perfect for this but I do not have a license and was denied when I asked for it to be added to the budget.

  • How do I create DNS entries for EC2 instances created by Auto Scaling?

    - by Evan
    I'm looking into using auto scaling groups for a tier of webservers that would be fronted by an ELB. One of the things I'm having a hard time with is how to give each new instance the proper DNS name. For example, I'd like webservers to have names like frontend-web-XXX.prod.example.com so their names would appear correct in logs and just ease of organization. I have two other tiers I'd ultimately like to make autoscaled and I'd like them to have names like api-web-XXX.prod.example.com as well. I have some experience with cloudformation templates and have spun up individual instances with associated Route53 records but I don't see any indication of how this can be done within an autoscaled group.

  • Store profile image of all users into single directory or per subdirectory id?

    - by Luccas
    I'm using amazon s3 as storage for users profile pic. I see that many websites generates large random filenames and put them into the same root directory like: http://xxx.us-east-1.amazonaws.com/aHR0cHM6Ly9mYmNkbi1wcm9maWxlLWEuYWthbWFpaGQubmV0L2hwcm9maWxlLWFrLWFzaDIvMjczMzkxXzEwMDAwMDMxMjAxMzg5OV81NTk3MjM4Mzdfbi5qcGc.jpg And my question is: What are the pros and cons of that approach? If I palce them into different directories, what problems I will have in future? http://xxx.us-east-1.amazonaws.com/users/id/username.jpg or http://xxx.us-east-1.amazonaws.com/users/id/random_number.jpg Thanks!

  • How can I create an AMI from an existing EC2 instance?

    - by Arkaaito
    (I suspect that this may already be answered somewhere, since it seems like it would be a common operation. But I can't find it, so...) I am a relative AWS newbie. I have inherited a running Amazon EC2 instance, with various items (Apache, MySQL, Sphinx, ...) installed on it and a bunch of configuration. I'd like to turn it into an AMI that I can spin up other instances from. I can't find any information on creating a custom AMI on Amazon's site - only the fact that you can, repeatedly referenced, as if to taunt me... I believe this is not an EBS-backed instance, just an "ordinary" one. I do not know what AMI it was originally created from. How would I create an AMI that I could use for spinning up other instances which will be identical except for the hostname?

  • ec2 ami device mapping

    - by hortitude
    I have large ec2 Ubuntu image and I'm just looking through the devices. I noticed from the metadata that % curl http://169.254.169.254/latest/meta-data/block-device-mapping/ami sda1 % curl http://169.254.169.254/latest/meta-data/block-device-mapping/ephemeral0 sdb However when I look what is actually mounted there is /dev/xvda1 and /dev/xvdb (and there is no /dev/sd* ) I know that both names look somewhat valid from the AWS documentation, but it looks to me from this like there is a mismatch in the instance metadata and what is actually on the machine. Why don't they match?

  • How do you keep up with Nagios/Capistrano configs when using EC2?

    - by imaginative
    I use Amazon EC2 for my mobile app. Depending on load of the application at a given time, I might spawn new instances and then take them down when load is lower to save costs. How does one keep up with Nagios configurations for such a dynamic environment? When one deals with managed hardware, configuration files are predictable. In this case Nagios, Capistrano and a bunch of other configuration files would need to be added. Capistrano needs to know where to deploy a new build to for an app server. Nagios needs to know to remove an existing instance or add a new instance for monitoring. Nagios also needs to know if a node was intentionally taken down or if the host is down due to error. How is this done with the wonderful world of VPS/dynamic instances?

  • Providing a static IP for resources behind AWS Elastic Load Balancer (ELB)

    - by tharrison
    I need a static IP address that handles SSL traffic from a known source (a partner). Our servers are behind an AWS Elastic Load Balancer (ELB), which cannot provide a static IP address; many threads about this here. My thought is to create an instance in EC2 whose sole purpose in life is to be a reverse proxy server having it's own IP address; accepting HTTPS requests and forwarding them to the load balancer. Are there better solutions?

  • identifying windows service

    - by András
    On my win7 machine when I watch a movie in XBMC, once per hour the desktop regains the focus. The movie keeps playing, but in the background now, so I can only hear it. It is quite irritating. I noticed, that the Windows Application log always contains two entres for this time: "The description for Event ID 0 from source Self-service Plug-in cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer." One entry is for starting, and one for stopping 60 seconds later. This keeps repeating, every two starts 3600 seconds apart. How can I repair it? How can I find out which service it is?

  • Is there some way Linux editors can tell the programming language without the file extension?

    - by vfclists
    I am editing some scripts on Linux without the languages file extensions, and it seems that the editors, namely vi, nano and gedit are not applying syntax highlighting because the filenames don't use the language extensions. Is there some parameters to be passed or some setting that can enable them to recognize the language? Update: After some googling I realize that bash has that ability, at least to do some parsing or check the shebang at the top determine the language. By default Ubuntu does not install the complete vim package, so after installing it, the shell files are recognized. I don't know about nano or gedit, but vi and its graphical counterpart will do.

  • How to configure Amazon Security Groups to achieve multi-tier architecture?

    - by ks78
    What is the preferred way to configure Amazon Security Groups to achieve a multi-tier architecture? Each of my instances has its own Security Group, which I only want to use for rules specific to an instance. I'd like to keep any rules which apply to multiple instances in a separate Security Group, which can then be assigned to instance Security Groups as necessary. As an example, I've setup a group called "admin", which allows administrative access from my IP. I added the "admin" group as the source to each of my instance security groups. However, I still can't access the instances from my IP without adding the rules directly to the instance's group. Am I missing something? Although it seems a multi-tier security architecture should be possible, it doesn't seem to be working.

  • Tracking costs within one AWS account

    - by caius howcroft
    I have what I'm sure is a very common problem. Our company has many projects and groups working for different clients. We do a lot of our development work in the cloud and deploy our solutions there. We have a VPC set up that isolates projects from each other in their own subnet and that VPC is getting a hardware VPN connection back to HQ. We need to keep track of the cost run up by every project. The way I currently implement this is by providing my own tools for starting and stopping instances which log which user (and thus which project) to bill the instance too. This works okay for BoxUsage costs but not for other costs. I could create a separate account for each project and use consolidated billing, this I think would allow me to pay once but track costs per "project", but I would then not be able to share common resources (like bring account B's running instances inside the same VPC). Does anyone have any suggestions? Cheers C

  • Can I use @import to import Kod's default style sheet into my own?

    - by Thomas Upton
    I understand that Kod is being actively developed and is prone to drastic changes in any area. I would like to modify some small things (like font face and size or certain colors) while still being able to benefit from any changes or updates to the default Kod stylesheet. I thought that I would be able to @import the default stylesheet into my own to achieve this. This is what ~/.kod/custom.css would look like, @import url("file:///Applications/Kod.app/Contents/Resources/style/default.css"); /* Change the default font face and color. */ body { font-family: Menlo, monospace; color: #efefef; } This stylesheet was set with the following defaults command, per the comments at the top of Kod's default CSS file: defaults write se.hunch.kod style/url ~/.kod/custom.css Unfortunately, this didn't work. When I first tried to reload the style, Kod crashed. It opened fine again, but the @import statement wasn't working, and Kod crashed every time I saved the custom.css file. Am I doing something wrong? Did I write my @import statement wrong? Is that not how @import is supposed to work? Did I miss some sort of documentation or Kod Google Groups post that mentions that Kod explicitly disallows this?

  • Multiple Remote Desktop Connection in Windows Server 2003?

    - by Joel Bradley
    My company is transitioning all user PC's to Windows 7 64-Bit in anticipation of the 2014 cutoff for Windows XP support. So far everything has been going great except for one specific piece of software that will not run in Windows 7. The current plan is to give everyone a cheap secondary PC to run this software but I feel that's a little much for software that's not even used all the time, although it is essential. I've suggested we install virtual machines but the company does not want to pay for the XP licences. I have access to a copy of Windows Server 2003 that is no longer being used and I was wondering if it was possible to create a remote desktop server. I know it can be done on a one-to-one basis, but this is a 15 person helpdesk. I'd like to be able to support multiple remote dekstop sessions, each with their own logins and dekstops. Is this possible? Are there any other alternatives to my issue? FYI, I've been told that XP mode is only free for consumers. There are costs when used in a corporate environment.

  • Microsoft CA certificate templates expires sooner than expected

    - by Tim Brigham
    The certificates my Microsoft CA is generating do not match the time period indicated in the template used. How can I resolve this? I recently created a new certificate template for use on my Linux boxes on my Microsoft CA (2008 R2 Enterprise). This template is approved for server and client authentication purposes with a validity period of 10 years - the expected lifetime of our Linux boxes - and the subject name supplied in the request. I have checked both the intermediate and offline CA - both have more than 10 years of life listed. Is there some kind of hard limit I'm hitting here?

  • How to set specific environment variables for Apache service run on Windows

    - by Jimm Chen
    I'm facing a problem. I use xampp 1.7.7 on Windows which installs a Apache service. I find that I have to some tweak to have all PHP modules load properly. For example, php_ldap.dll cannot be loaded. It is mysterious why it cannot be loaded until I tried to run httpd.exe from command line, which reveals that libsasl.dll cannot be founded. Actually, there exist D:\xampp\php\libsasl.dll but httpd.exe cannot find it. OK. The best way is to add D:\xampp\php to PATH env-var. Now my question is: How do I set a specific PATH value for that specific Apache service but not system wide. -- because I think it is better not to disturb other processes with that extra PATH value. Is there a general way to do that for a specific Windows service? or, is there a Apache specific way to load extra env-var settings from some specific configuration files?

  • How to put 1000 lightweight server applications in the cloud

    - by Dan Bird
    The company I work for sells a commercial desktop/server app that runs on any non dedicated Windows PC or server and uses Tomcat for all interactions with the application. Customers are asking that we host their instance of the application so they don't have to run it locally on their own servers. The app is lightweight and an average server, in theory, could handle 25-50 instances before users would notice a slowdown. However only 1 instance can run per Windows instance (because the application writes to a common registry branch) so we'd need something like VMWare to create 25-50 Windows instances. We know we eventually need to reprogram to make it truly cloud-worthy but what would you recommend for a server farm or whatever for this? We don't have the setup to purchase our own servers so we must use a 3rd party. We have budgeted $500 - $1000 per year per customer for this service. Thanks in advance for your suggestions, experiences and guidance.
