• Apt pin and self hosted apt repo

  - by Hamish Downer

  We have our own apt/deb repository with a handful of packages where we want to control the version. Crucially this includes puppet, which can be sensitive to versions being different. I want our desktops to only get puppet from our repository, but also for people to be able to add their own PPAs, enable backports etc. The current problem we have is backports on Ubuntu Lucid. Some important lines from /etc/apt/sources.list: deb http://gb.archive.ubuntu.com/ubuntu/ lucid main restricted universe multiverse deb http://gb.archive.ubuntu.com/ubuntu/ lucid-updates main restricted universe multiverse deb http://gb.archive.ubuntu.com/ubuntu/ lucid-backports main restricted universe multiverse deb http://security.ubuntu.com/ubuntu/ lucid-security main restricted universe multiverse deb http://deb.example.org/apt/ubuntu/lucid/ binary/ And in /etc/apt/preferences.d/puppet: Package: puppet puppet-common Pin: release a=binary Pin-Priority: 800 Package: puppet puppet-common Pin: release a=lucid-backports Pin-Priority: -10 Currently policy says: $ sudo apt-cache policy puppet puppet: Installed: (none) Candidate: (none) Package pin: 2.7.1-1ubuntu3.6~lucid1 Version table: 2.7.1-1ubuntu3.6~lucid1 -10 500 http://gb.archive.ubuntu.com/ubuntu/ lucid-backports/main Packages 100 /var/lib/dpkg/status 2.6.14-1puppetlabs1 -10 500 http://deb.example.org/apt/ubuntu/lucid/ binary/ Packages 0.25.4-2ubuntu6.8 -10 500 http://gb.archive.ubuntu.com/ubuntu/ lucid-updates/main Packages 500 http://security.ubuntu.com/ubuntu/ lucid-security/main Packages 0.25.4-2ubuntu6 -10 500 http://gb.archive.ubuntu.com/ubuntu/ lucid/main Packages If I use n= instead of a= then I get Package pin: (not found) I'm just plain confused at this point as to what I should use.

• Recommendations for remote server management software, similar to Puppet or Canonical Landscape?

  - by rmh

  We currently have five Ubuntu 10.04 LTS servers, and keeping them all up-to-date is starting to be a pain. I've been looking into solutions like Puppet and Canonical Landscape. Out of the two I prefer Puppet -- it would be useful to be able to ensure the permissions of various directories on the machines, and define groups and users on the server which are then propagated to clients. Is there any other software in this vein that I should be taking a look at?

• FLEX: how to better align my Tile component to the puppet (and how to solve roll over out effects) ?

  - by Patrick

  hi, At the moment my Puppets are larger on the left if I add them the <mx:Tile> component (with tags): http://dl.dropbox.com/u/72686/puppets.png how can I move my Tile component to the right ? In order to align with the left border of my puppets ? <mx:Tile id="tagsPopup" width="200" visible="false" > <mx:LinkButton label="Tag1" /> <mx:LinkButton label="Tag2" /> <mx:LinkButton label="Tag3" /> <mx:LinkButton label="Tag4" /> </mx:Tile> <mx:VBox verticalGap="0"> <mx:Image id="puppet" source="@Embed(source='../icons/userIcon.png')" /> <mx:Label id="username" text="Nickname" visible="false" fontWeight="bold" /> </mx:VBox> 2nd Question: I want to add objects on top of the puppets, some of them are visible only when the mouse is over, and they are overlying the ones are permanently visible. How do you suggest to implement it ? I was thinking to add in MXML all visible elements and then use Actionscript to add the fade in fade out components. However I just realize it is quite tricky, because I want the user select for example tag1, tag2 and tag3, with the mouse. Instead now they disappear when the mouse rolls out from the puppet image. Any guideline ? thanks

• How do you guys handle custom yum repository?

  - by luckytaxi

  I have a bunch of tools (nagios, munin, puppet, etc...) that gets installed on all my servers. I'm in the process of building a local yum repository. I know most folks just dump all the rpms into a single folder (broken down into the correct path) and then run createrepo inside the directory. However, what would happen if you had to update the rpms? I ask because I was going to throw each software into its own folder. Example one, put all packages inside one folder (custom_software) /admin/software/custom_software/5.4/i386 /admin/software/custom_software/5.4/x86_64 /admin/software/custom_software/4.6/i386 /admin/software/custom_software/4.6/x86_64 What I'm thinking of ... /admin/software/custom_software/nagios/5.4/i386 /admin/software/custom_software/nagios/5.4/x86_64 /admin/software/custom_software/nagios/4.6/i386 /admin/software/custom_software/nagios/4.6/x86_64 /admin/software/custom_software/puppet/5.4/i386 /admin/software/custom_software/puppet/5.4/x86_64 /admin/software/custom_software/puppet/4.6/i386 /admin/software/custom_software/puppet/4.6/x86_64 Ths way, if I had to update to the latest version of puppet, I can save manage the files accordingly. I wouldn't know which rpms belong to which software if I threw them into one big folder. Makes sense?

• Has anyone used tools like (Chef, Salt, Puppet, CfEngine) to configure a 2008 Win Server with Sql?

  - by Development 4.0

  I have been looking into tools to automate the creation of servers. For two different reasons: Production Development machines I love the idea of the immutable server. I have seen the tools demoed and used successfully on *nix boxes running Rails or Lamp etc. Has anyone found a good way to do this in the Microsoft stack? I would like to get in on the fun and create scripts that will install Windows, patch it according to specification, deploy Sql Server create scripts to build out a database and just for fun deploy SharePoint and configure it, and then deploy a SharePoint solution to it. I can get part of the way, install Windows manually, install Sql Server manually, use Powershell to do all the configuration and setup. Install SharePoint and configure part of it, then powershell for the rest of the configuration and deploying a solution. I would love to have the ability to run one script though, or at least one unified process. I can, and have mostly used VM template images and then instantiated them, but the creation of the template is usually a manual step.

• Kickstart CentOS 6 prompting for TCP/IP with network set to DHCP

• How to version lock packages in Ubuntu?

  - by Sandra

  On CentOS exists the yum versionlock option, where you can lock a package to a specific version, so it is never upgraded past that. I would like that puppet-server-2.7.19-1 puppet-2.7.19-1 stays on 2.7, and never upgraded to 3.0. Puppet Labs have released 3.0 and put it into the stable repo, so 2.7 will get upgraded to 3.0, which is not backwards compatible. Does Ubuntu have something similar to yum versionlock?

• Do Not Uninstall Flag on Apt?

  - by Daniel C. Sobral

  Does the Debian/Ubuntu package infrastructure has some way of marking packages so that they never get uninstalled, no matter the pinning of other packages? My problem is that, sometimes, packages installed by Puppet (coming from non-standard repositories, of course) cause other packages to get uninstalled -- in particular, openssh-{server,client}. The way this happens is that package A and B depend on different versions of package C. If A is installed and one asks to install B, then the version of C changes. The new version of C is incompatible with A, so A gets uninstalled. The funny thing is that the process is then reversed, as, on the next run, Puppet notices that A is not installed and tries to install it. So, basically, I want to make sure A never gets uninstalled, which would prevent B from getting installed. That would be reported as an error, making me aware of the issue. If anyone cares, Puppet uses the following command to install packages: /usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install <package>

• Crossplatform "jail" for an application

  - by Alexander

  We currently have a variety of systems (Linux, Solarix, *BSD, HP-UX ...) on which we are not allowed to install anything into / (but I have root access. That's strange, I know). But we'd like to run Puppet on all of them. So, the obvious idea is to install Puppet with all prebuilt dependencies into some isolated tree, something like "jail", which will allow to use dependences from some prefix and to access the host system. The big advatanges would be uniform deployment and updates. One solution that came to my mind is to deploy Gentoo Prefix, and install Puppet there with package manager. However, this requires a lot of extra space and some manual patching for each system. Maybe there are some more elegant and simple solutions?

• Assign fixed IP address via DHCP by DNS lookup

  - by Janoszen

  Preface I'm building a virtualization environment with Ubuntu 14.04 and LXC. I don't want to write my own template since the upgrade from 12.04 to 14.04 has shown that backwards compatibility is not guaranteed. Therefore I'm deploying my virtual machines via lxc-create, using the default Ubuntu template. The DNS for the servers is provided by Amazon Route 53, so no local DNS server is needed. I also use Puppet to configure my servers, so I want to keep the manual effort on the deployment minimal. Now, the default Ubuntu template assigns IP addresses via DHCP. Therefore, I need a local DHCP server to assign IP addresses to the nodes, so I can SSH into them and get Puppet running. Since Puppet requires a proper DNS setup, assigning temporary IP addresses is not an option, the client needs to get the right hostname and IP address from the start. Question What DHCP server do I use and how do I get it to assign the IP address based only on the host-name DHCP option by performing a DNS lookup on that very host name? What I've tried I tried to make it work using the ISC DHCP server, however, the manual clearly states: Please be aware that only the dhcp-client-identifier option and the hardware address can be used to match a host declaration, or the host-identifier option parameter for DHCPv6 servers. For example, it is not possible to match a host declaration to a host-name option. This is because the host-name option cannot be guaranteed to be unique for any given client, whereas both the hardware address and dhcp-client-identifier option are at least theoretically guaranteed to be unique to a given client. I also tried to create a class that matches the hostname like this: class "my-client-name" { match if option host-name = "my-client-name"; fixed-address my-client-name.my-domain.com; } Unfortunately the fixed-address option is not allowed in class statements. I can replace it with a 1-size pool, which works as expected: subnet 10.103.0.0 netmask 255.255.0.0 { option routers 10.103.1.1; class "my-client-name" { match if option host-name = "my-client-name"; } pool { allow members of "my-client-name"; range 10.103.1.2 10.103.1.2; } } However, this would require me to administer the IP addresses in two places (Amazon Route53 and the DHCP server), which I would prefer not to do. About security Since this is only used in the bootstrapping phase on an internal network and is then replaced by a static network configuration by Puppet, this shouldn't be an issue from a security standpoint. I am, however, aware that the virtual machine bootstraps with "ubuntu:ubuntu" credentials, which I intend to fix once this is running.

• "No route to host" with ssl but not with telnet

  - by Clemens Bergmann

  I have a strange problem with connecting to a https site from one of my servers. When I type: telnet puppet 8140 I am presented with a standard telnet console and can talk to the Server as always: Connected to athena.hidden.tld. Escape character is '^]'. GET / HTTP/1.1 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>400 Bad Request</title> </head><body> <h1>Bad Request</h1> <p>Your browser sent a request that this server could not understand.<br /> Reason: You're speaking plain HTTP to an SSL-enabled server port.<br /> Instead use the HTTPS scheme to access this URL, please.<br /> <blockquote>Hint: <a href="https://athena.hidden.tld:8140/"><b>https://athena.hidden.tld:8140/</b></a></blockquote></p> <hr> <address>Apache/2.2.16 (Debian) Server at athena.hidden.tld Port 8140</address> </body></html> Connection closed by foreign host. But when I try to connect to the same host and port with ssl: openssl s_client -connect puppet:8140 It is not working connect: No route to host connect:errno=113 I am confused. At first it sounded like a firewall problem but this could not be, could it? Because this would also prevent the telnet connection. As Firewall I am using ferm on both servers. The systems are debian squeeze vm-boxes. [edit 1] Even when I try to connect directly with the IP address: openssl s_client -connect 198.51.100.1:8140 #address exchanged connect: No route to host connect:errno=113 Bringing down the firewalls on both hosts with service ferm stop is also not helping. But when I do openssl s_client -connect localhost:8140 on the server machine it is connecting fine. [edit 2] if I connect to the IP with telnet it also is not working. telnet 198.51.100.1 8140 Trying 198.51.100.1... telnet: Unable to connect to remote host: No route to host The confusion might come from IPv6. I have IPv6 on all my hosts. It seems that telnet uses IPv6 by default and this works. For example: telnet -6 puppet 8140 works but telnet -4 puppet 8140 does not work. So there seems to be a problem with the IPv4 route. openssl seems to only (or by default) use IPv4 and therefore fails but telnet uses IPv6 and succeeds.

• What do you use RightScale for?

  - by npt

  I'm currently evaluating whether to use RightScale to manage a production environment in EC2. I intend to use Puppet for configuration management either way (the declarative approach seems far better than running scripts), am running a somewhat nonstandard stack (e.g. MongoDB), and am uncertain about how much value RightScale would add relative to Puppet + Amazon's auto-scaling + another hosted monitoring system. Those who use RightScale, what features do you find important? Is its auto-scaling support (including keeping single instances running) more powerful than Amazon's?

• Why is there only one configuration management tool in the main repository?

  - by David

  How is it that Cfengine does not exist in the Ubuntu (10.04 LTS) Main Repository? I can't find a discussion of this anywhere (using Google). The only configuration management in Ubuntu Main seems to be Puppet. I looked for a wide variety of others as well - all from Wikipedia's list of configuration management tools - and none of them are present in Ubuntu main. I looked for bcfg2, opensymbolic, radmind, smartfrog, spacewalk, staf, synctool, chef - none are present. From my vantage point as a system administrator, I would have expected to find at least bcfg2, puppet, cfengine, and chef (as the most widely used tools). Why is cfengine (or chef and others) not included in Ubuntu main? Why is there only one configuration management tool in Ubuntu main? By the way - the reason this is important in the context of server administration is because Ubuntu main is fully supported by the Ubuntu team with updates and security updates; the other repositories are not.

• Bypass a licence agreement when mounting a DMG on the command line

I use the following to mount them: sudo /usr/bin/hdiutil mount -plist -nobrowse -readonly -quiet -mountrandom /tmp Program.dmg The problem is that some .dmg files come with a license attached, and so script is stuck accepting the license. (There is no stdin/out when running with puppet, so I can't manually approve it to continue.) Is there a way to pre-approve or force-approve the license?

• Amazon EC2, fastest way to get a node into an existing cluster

  - by imaginative

  I'm new to Amazon AWS. A lot of the time I hear about people folks spawning instances and almost instantly putting them behind a load balancer and into an existing cluster. In the traditional world of managed machines, this would include provisioning hardware, installing an OS, configuring the network on the machine and once the network is available, use a tool of your choice such as CFengine, Puppet or Chef to bootstrap the machine based on its class. It seems like there are "shortcuts" that are able to get a server of a particular class up and running in Amazon EC2. If I have a particular stack running on my server, such as erlang, tomcat6 etc.. what's the fastest way to get these up and running and hooked into Amazon's load balancer? From network, to software stack to kernel tuning? Is it a combination of creating an AMI then running a tool like Puppet against the new instance? Any idea

• Windows Server Configuration Management Best Practices

  - by Anton Gogolev

  Chef/Pupper/Ansible are cool and all, but they are second-class citizens on Windows at best. We have a bunch of "snowflake" (one of a kind) machines (baremetal and virtual) that nobody really know what's going on with. What I want is to start establishing basic configuration management for said servers, starting from installing Windows, installing and enabling various Roles and Features, setting up Services, Shares, Users and deploying webapps. PowerShell DSC looks promising, but it's not yet here and appears to be over-engineered, Puppet and the like are again not first-class. There's a bunch of tooks and TLAs like Windows ADK, DISM, OCSetup, etc. and it seems to me that the "Configuration Management" story on Windows is not precisely rainbows and unicorns. What I want is a Puppet/Chef-like, lightweight tool (no System Center Configuration Management, please) which would allow us to "version-control our server infrastructure" and bring all the benefits of CM. So, where do I look for the tool that does this kind of thing?

  As much as there is often a lot discussion about configuration items inside the SMF repository (like the hostname), it brings an important advantage: It introduces the concept of dependencies to configuration changes. What services have be restarted when i change a configuration item. Do you remember all the services that are dependent on the hostname and need a restart after changing it? SMF solves this by putting the information about dependencies into it configuration. You define it with the manifests. However, as much configuration you may put into SMF, most applications still insists to get it's configuration inside the traditional configuration files, like the resolv.conf for the resolver or the puppet.conf for Puppet. So you need a way to take the information out of the SMF repository and generate a config file with it. In the past the way to do so, was some scripting inside the start method that generated the config file before the service started. Solaris 11.2 offers a new feature in this area. It introduces a generic method to enable you to create config files from SMF properties. It's called SMF stencils. (read more)

• FLEX: sequence of puppets... 3 requirements

  - by Patrick

  hi, I'm implementing this sequence of puppets in flex: http://dl.dropbox.com/u/72686/itemsSequence.png I want to show the caption when the mouse rolls over the puppet I want the user being able to click on the buttons of the caption (so the caption doesn't have to disappear when I move the mouse out from the user over the caption). I don't want the puppet component to become bigger when the caption is added (it becomes visible), because the puppets have to stay nearby each other, I cannot resize the objects. So.. I need some guidelines to do it. More precisely: 1) Should I add the components in MXML or pure actionscript ? 2) If I use MXML, should I add also the caption to the flex model, and make it invisible and then change the value with actionscript ? What's the common way to implement it ? thanks
