• Retrieve a domain name based on an IP Address?

  - by Neil Kodner

  I'm reviewing some apache logs, specifically with respect to downloaded files. I'm interested in knowing, if possible, which domain is responsible for the download, given an IP address. I've given nslookup a try and it seems to (mostly) get the job done but it returns all sorts of extraneous information. Ideally, I pass in an IP and receive a domain back. Before I write a shell script to parse the output of nslookup to capture the domain, I'd like to know if this is the best way of approaching this problem, or if there is a more tried-and-true method of doing this. Specifically, I'd like to know if an address resolves to an amazonaws.com domain. I understand that this might be difficult because EC2 machines are dynamically created and destroyed - I'd like to know if the IP addresses for AWS/EC2/EMR machines fit any sort of addressing pattern.

• Cloud based backup solutions based on open standards?

  - by Rick

  I am looking for a solution to backup and consolidate important media from a couple Windows laptops and Mac laptop. I would like a solutions that based on open standards, so my data isn't trapped by proprietary formats and proprietary protocols. I would like the ability to switch clients or change providers in the future. For example, something like Jungle Disk plus S3 sounds like a great option. However, I am having trouble confirming how or if this can be setup meeting this criteria. Are there any real or de-facto standards for treating S3 as a filesystem? If so, what Windows and Mac clients support these standards?

• Session persistence between multiple Rails / Unicorn servers with Redis as session_store on AWS

  - by d_ethier

  I've got 2 nginx EC2 instances pointing to 2 Unicorn EC2 instances in a round robin load balanced configuration. The two nginx instances are being the Elastic Load Balancer. Both Unicorn instances have a Redis session_store configured which is in a master/slave configuration with an Elastic IP attached to the master. I've tried configuring the session stickiness on the load balancer, but sessions are lost on each page refresh. I'm using the redis-store gem for the session_store configuration and redis support. Anyone have any ideas as to why this is not working?

• Mount EC2 instance via SSH on Mac OS X

  - by darkporter

  OK I just can't figure this out. I have an EC2 instance, which I'm able to SSH into just fine with: ssh -i XXXX.pem [email protected] I can even make it slick from the command line by creating a ~/.ssh/config with this in it: Host XXXX HostName XXXX User ubuntu IdentityFile ~/.ec2/XXXX.pem Which allows me to simple do a ssh XXXX with no -i option. Now, I want to mount this via SSH. I've tried MacFuse/SSHFS, MacFusion and ExpandDrive, but no luck. It's supposed to "just work" but the SSH-related command line utilities and the Keychain Access program in OS X is confusing and opaque to me. From what I've read, these GUI programs don't care about .ssh/config, they care about the Keychain. Somehow I can associate my domain name I'm connecting to with a particular "identity" private key file (.pem file) but I have no idea how. I tried this: ssh-add -K XXXX.pem Which does add to the Keychain but it's not associated to a particular domain. These GUI mounting programs I mentioned all just spin and do nothing when I try to connect passwordless. No keychain prompt, no nothing. I've pretty much given up and I'm thinking about just setting up an SMB server, but I'd rather just go over SSH since I believe it's possible.

• 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?

• root locked out of EC2

  - by Paco

  I was in the process of disabling root logins on an AWS EC2 instance. Right after setting PermitRootLogin no and restarting sshd, I closed the terminal on accident -- before setting up users with sudo privileges. The result is that my key to get into the instance as root does not work (sshd forbids it) and when I log into the instance using my regular user I can't gain root privileges (the root password was never set). The instance is running ubuntu 8.10. Anyone have any idea how can I fix this?

• Is it secure to store the cert/key on a private AMI?

  - by Phillip Oldham

  Are there any major security implications to bundling a private AMI which contains the private key/certificate & environment variables? For resiliency I'm creating an EC2 image which should be able to boot and configure itself without any intervention. After boot it will attempt to: Attach & mount specific EBS volume(s) Associate a specific Elastic IP Start issuing backups of the EBS volume(s) to S3 However, to do this it will need the private key/pem files and will need certain environment variables to be available on start-up. Since this is a private AMI I'm wondering if it will be "safe" to store these variables/files directly in the image so that I don't need to specify any user-data information and can therefore start a new instance remotely (from my iPhone, if needed) should the instance be terminated for any reason.

• Synchronize large objects to S3 efficiently

  - by emk

  I need to synchronize about 30GB of git repositories to S3. These repos may contain some very large pack files, on the rough order of 2GB. I know that S3 has recently added support for large objects, and has new APIs that allow the objects to be uploaded as several parallel chunks. Is there a good command-line tool for Linux that allows me to efficiently synchronize large objects with S3 in a fashion similar to s3sync?

• Trying to send email from nagios

  - by batman

  I'm very new to Nagios. I'm trying to send email alerts. But that doesn't seem to be working. But in my log of nagios I can see this : SERVICE ALERT: Appserver;Tmp directory;CRITICAL;HARD;1; Where host notifications are generated via email, only service alerts are not working. And when I look at sendEmail log I can see this : Sep 14 12:38:39 x.x.x.x. sendEmail[23005]: ERROR => You must specify a 'from' field! Try --help.

• Issues Deploying Functional WAR to Elastic Beanstalk with Tomcat7

  - by BFar

  I am currently deploying OpenTripPlanner (http://github.com/OpenPlans/OpenTripPlanner.git) to Elastic Beanstalk. I'm able to successfully build and deploy opentripplanner with my own customized settings on an ec2. I have set it up so that the appropriate WAR file can be placed in the Tomcat/Webapps folder, and when Tomcat is started up, it will auto-deploy, and even download open trip planner's graph.obj from an S3. All of that works just fine, except when I try to deploy to Elastic Beanstalk. When I upload to Elastic Beanstalk, the log shows that my WAR file is successfully unpacked & successfully downloads the graph.obj from my S3. The only difference is that then nothing happens and I can't load the site in my browser. The health is RED, and I can't figure out what is going on. I've tried looking into ports and dns issues, but I can't determine what's wrong. Anyone have any ideas? Why would a WAR that works on tomcat7 outside of Beanstalk fail to be accessible?

• How can I setup nginx to serve virtualhosts with rails(unicorn/passenger) and php-fpm

  - by NewAlexandria

  I would like to serve multiple sites on one instance. I install nginx, php-fpm, and a rails app. I use sites like this to guide me. I configure php-fpm to listen to a local socket listen = /var/run/php-fpm/php-fpm.sock I configure ngnix with multiple hosts: include /etc/nginx/conf.d/*.conf I have several site php conf files like /etc/nginx/conf.d/site1.conf server { listen 80; server_name site1.com www.site1.com; root /var/www/site1; location / { index index.html index.php; } location ~ \.php$ { fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; fastcgi_index index.php; include fastcgi_params; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name; } } and rails site conf files like upstream rails { server 127.0.0.1:3000; } server { listen 80; server_name site2.com www.site2.com; root /var/www/site2; location / { proxy_pass http://rails; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; proxy_set_header X-Url-Scheme $scheme; } } I have a unicorn rails server running via rails s -p 3000 Yet, no sites come up for either site1.com or site2.com. I can get to the rails site at www.site2.com:3000 What is wrong? I've spent 2 days (nearly 30hr) trying many different blogs, SO / SF questions, etc. Please share your insight or answer. edit 1: No log entries are created when I try to visit either site. It's like the requests never come in.

• 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 to know if my nginx is in good health?

  - by Howard

  I am running a nginx on EC2 (m1.small) for SSL termination. I am using 2 workers on Ubuntu, with latest nginx (stable), the network throughput is around 2Mbps and system load average is around 2 to 3. I am wondering if this system is in good health for now, e.g. what is the queue length (I know nginx can handle a lot of concurrent request, but I mean before the request is being served, how many of them need to wait before being served) what is the average queue time for a given request to be served. I want to know because if my nginx is cpu bounded (e.g. due to SSL), I will need to upgrade to a faster instance. My current nginx status Active connections: 4076 server accepts handled requests 90664283 90664283 104117012 Reading: 525 Writing: 81 Waiting: 3470

• sysbench memory test on ec2 small instance

  - by caribio

  I'm seeing a problem with sysbench memory test (the default version that's compiled in). This is on Ubuntu Maverick, sysbench installed via apt-get install sysbench. Running the same thing on Ubuntu @ Rackspace worked just as expected. While the CPU and I/O tests worked fine on EC2 servers, the memory test just runs without doing anything (notice the 0M in the test results). The instance used was the publicly available 'stock' Ubuntu image with no changes to it: ./ec2-run-instances ami-ccf405a5 --instance-type m1.small --region us-east-1 --key mykey Supplying more arguments (such as: --memory-block-size=1K --memory-total-size=102400M) didn't help.

• How frequent are network partitions on cloud services?

  - by roja

  Much is made of the CAP trade-off for data storage where conflicts can be introduced if there is a network partition. My question is there any evidence that this is a problem that arises with any significant frequency in modern cloud IAAS services e.g.; EC2, Azure, Rackspace. Is it a problem which, despite being a theoretical roadblock in constructing idealised distributed systems is, in fact, a non-issue for all practical concerns? Has anyone experienced a network partition within one of these systems (within a single data-centre?) If so would you be willing to share any details?

• s3cmd run on command line not on cron

• Intermittent apt-get 'no installation candidate' error on fabric deploy

  - by jberryman

  I'm experiencing a strange issue with a fabric script I'm using to bootstrap a server on EC2. I launch a stock Ubuntu 12.04 AMI, wait for it to start, then proceed with: with settings(host_string="ubuntu@%s" % i.dns_name, connection_attempts=30): sudo('apt-get -qy update') sudo('apt-get -qy install --no-install-recommends mdadm') # don't install postfix #etc... The apt-get update appears to run fine and gives no errors, however (2/3 of the time or so) installing mdadm throws a "no installation candidate" error. When I ssh into the server and run apt-get install mdadm I get the same error. Running apt-get update by hand, then the package installs fine. Any ideas on what might be happening, or ideas for debugging?

• EC2 AMI won't boot after edit

  - by Eric Lars0n

  I did something stupid, I got a new laptop and copied everything over to the new one, then wiped the old one clean. Then I realized that I forgot to copy the private key out of .ssh that I use to connect to my AWS EBS backed instance. So I can't log in to my custom AMI. So I created a new Volume from the Snapshot of the AMI, then started up a public instance and attached the Volume to it, edit the sshd_config to allow for password log in. Unmounted the volume, detached it, made a snapshot of it, then made a new AMI from the snapshot. The new AMI launches, but never passes the Status Checks and is not reachable. What am I doing wrong? Or alternatively how can I fix my problem? Edit: Adding some of the console output Linux version 2.6.16-xenU ([email protected]) (gcc version 4.0.1 20050727 (Red Hat 4.0.1-5)) #1 SMP Mon May 28 03:41:49 SAST 2007 BIOS-provided physical RAM map: Xen: 0000000000000000 - 000000006a400000 (usable) 980MB HIGHMEM available. 727MB LOWMEM available.

• Optimal Instance Size for EC2 Sharepoint Server

  - by Rob Wilkerson

  I'm surprised that I can't find any info about this, but I'm not a Windows admin and just a novice EC2 user. I have a client who wants to stand up a Sharepoint server on EC2 for internal use. The team is small (10-20) folks and traffic will be light. Mostly, the client is looking for one place to store documents (and revisions of documents) while making access easy for authenticated users anywhere in the world. They've settled on Sharepoint and have other EC2 instances so that seems like the natural fit, but I'm trying to figure out what to recommend for them. I'm currently thinking about a Medium instance. I'm afraid to go smaller because I think Windows would need a fair amount of memory just to run, but I'm very open to suggestions. Any advice would be much appreciated. I expect that the storage itself would happen in an EBS mount, but again, suggestions welcome. Thanks for your input.

• Windows 2003 server RRAS on VPC

  - by Saif

  I'm trying to setup a L2TP VPN server(to give user access on to all my VPN instance) on a Windows 2003 instance running on my VPC. While trying to enable RRAS I'm getting error, "less than two network interfaces were detected on this machine". Eventually it's because there's only one network interface available, the which has private IP. I have elastic IP assigned to this instance as well. But RRAS can't see this. What should I do to RRAS to be able to see the interface with elastic IP?

• Has ec2 made self-hosting possible for 'amateur' sysadmins possible?

  - by Blankman

  I'm a developer, and it seems ec2 has made it possible for a amateur sysadmin like me to setup and maintain a fairly large set of servers. Now I don't mean to undermine real sys admins, as I know the value of them but what I am trying to get at is that someone like me can setup and maintain a cluster of servers (front end web servers, with some db servers) using tools like ec2 and capistrano with the help of google. Now this isn't something I would do as a long term thing, but as a startup, one-man operation, I think I can pull this off until business takes off and I can hire this important role out. With ec2, I get my firewall, so I basically open up port 80 on my public facing server, which will run haproxy and route requests to my cluster of servers. Ofcourse I am simplifying the setup, but just want a feel for what you guys think about my perception. My application is a web application, that will be runing Ruby on rails (passenger) and talking to mysql or postgresql.
