dns networking system bind freeipa

shared by 張 旭 on 30 Aug 19 - No Cached
  • FreeIPA DNS integration allows administrator to manage and serve DNS records in a domain using the same CLI or Web UI as when managing identities and policies.
  • Single-master DNS is error prone, especially for inexperienced admins.
  • a decent Kerberos experience.
  • ...14 more annotations...
  • Goal is NOT to provide general-purpose DNS server.
  • DNS component in FreeIPA is optional and user may choose to manage all DNS records manually in other third party DNS server.
  • Clients can be configured to automatically run DNS updates (nsupdate) when their IP address changes and thus keeping its DNS record up-to-date. DNS zones can be configured to synchronize client's reverse (PTR) record along with the forward (A, AAAA) DNS record.
  • It is extremely hard to change DNS domain in existing installations so it is better to think ahead.
  • You should only use names which are delegated to you by the parent domain.
  • Not respecting this rule will cause problems sooner or later!
  • DNSSEC validation.
  • For internal names you can use arbitrary sub-domain in a DNS sub-tree you own, e.g. int.example.com.. Always respect rules from the previous section.
  • General advice about DNS views is do not use them because views make DNS deployment harder to maintain and security benefits are questionable (when compared with ACL).
  • The DNS integration is based on the bind-dyndb-ldap project, which enhances BIND name server to be able to use FreeIPA server LDAP instance as a data backend (data are stored in cn=dns entry, using schema defined by bind-dyndb-ldap
  • FreeIPA LDAP directory information tree is by default accessible to any user in the network
  • As DNS data are often considered as sensitive and as having access to cn=dns tree would be basically equal to being able to run zone transfer to all FreeIPA managed DNS zones, contents of this tree in LDAP are hidden by default.
  • standard system log (/var/log/messages or system journal)
  • BIND configuration (/etc/named.conf) can be updated to produce a more detailed log.

  • in AngularJS, we have a separate model layer that we can manage in any way we want, completely independently from the view.
  • keep your concerns separate
  • do DOM manipulation and augment your view with directives
  • ...34 more annotations...
  • DI means that you can declare components very freely and then from any other component, just ask for an instance of it and it will be granted
  • do test-driven development iteratively in AngularJS!
  • only do DOM manipulation in a directive
  • with ngClass we can dynamically update the class;
  • ngBind allows two-way data binding;
  • ngShow and ngHide programmatically show or hide an element;
  • The less DOM manipulation, the easier directives are to test, the easier they are to style, the easier they are to change in the future, and the more re-usable and distributable they are.
  • still wrong.
  • Before doing DOM manipulation anywhere in your application, ask yourself if you really need to.
  • a few things wrong with this
  • jQuery was never necessary
  • use angular.element and our component will still work when dropped into a project that doesn't have jQuery.
  • just use angular.element
  • the element that is passed to the link function would already be a jQuery element!
  • directives aren't just collections of jQuery-like functions
  • Directives are actually extensions of HTML
  • If HTML doesn't do something you need it to do, you write a directive to do it for you, and then use it just as if it was part of HTML.
  • think how the team would accomplish it to fit right in with ngClick, ngClass, et al.
  • Don't even use jQuery. Don't even include it.
  • ry to think about how to do it within the confines the AngularJS.
  • In jQuery, selectors are used to find DOM elements and then bind/register event handlers to them.
  • Views are (declarative) HTML that contain AngularJS directives
  • Directives set up the event handlers behind the scenes for us and give us dynamic databinding.
  • Views are tied to models (via scopes). Views are a projection of the model
  • In AngularJS, think about models, rather than jQuery-selected DOM elements that hold your data.
  • AngularJS uses controllers and directives (each of which can have their own controller, and/or compile and linking functions) to remove behavior from the view/structure (HTML). Angular also has services and filters to help separate/organize your application.
  • Think about your models
  • Think about how you want to present your models -- your views.
  • using the necessary directives to get dynamic databinding.
  • Attach a controller to each view (using ng-view and routing, or ng-controller)
  • Make controllers as thin as possible.
  • You can do a lot with jQuery without knowing about how JavaScript prototypal inheritance works.
  • jQuery is a library
  • AngularJS is a beautiful client-side framework

  • update-policy only applies to, and may only appear in, zone clauses. This statement defines the rules by which DDNS updates may be carried. It may only be used with a key (TSIG or SIG(0)) which is used to cryptographically sign each update request. It is mutually exclusive with allow-update in any single zone clause. The statement may take the keyword local or an update-policy-rule structure. The keyword local is designed to simplify configuration of secure updates using a TSIG key and limits the update source only to localhost (loopback address, 127.0.0.1 or ::1), thus both nsupdate (or any other application using DDNS) and the name server being updated must reside on the same host.

shared by 張 旭 on 19 Jan 19 - No Cached
  • A PKI allows you to bind public keys (contained in SSL certificates) with a person in a way that allows you to trust the certificate.
  • Public Key Infrastructures, like the one used to secure the Internet, most commonly use a Certificate Authority (also called a Registration Authority) to verify the identity of an entity and create unforgeable certificates.
  • An SSL Certificate Authority (also called a trusted third party or CA) is an organization that issues digital certificates to organizations or individuals after verifying their identity.
  • ...9 more annotations...
  • An SSL Certificate provides assurances that we are talking to the right server, but the assurances are limited.
  • In PKI, trust simply means that a certificate can be validated by a CA that is in our trust store.
  • An SSL Certificate in a PKI is a digital document containing a public key, entity information, and a digital signature from the certificate issuer.
  • it is much more practical and secure to establish a chain of trust to the Root certificate by signing an Intermediate certificate
  • A trust store is a collection of Root certificates that are trusted by default.
  • there are four primary trust stores that are relied upon for the majority of software: Apple, Microsoft, Chrome, and Mozilla.
  • a revocation system that allows a certificate to be listed as invalid if it was improperly issued or if the private key has been compromised.

  • If you want to have redundancy, you must have the zone data accessible on multiple servers.
  • The Slave zone is a read-only copy of the zone data.
  • Most of the times Slave DNS zones are copies of Master zones.
  • If you try to change a DNS record on a Secondary zone, it can redirect you to another zone with read/write access. By itself, it can’t change it.

  • Forwarders are also useful if you need to shunt name resolution to a particular name server
  • If you designate one or more servers at your site as forwarders, your name servers will send all their off-site queries to the forwarders first.

  • ...2 more annotations...
  • If a resolver requests records that are already in the name server's authoritative data or cached data, the name server answers with that information
  • if the records aren't in its database, the name server sends the query to a forwarder and waits a short period for an answer before resuming normal operation and contacting the remote name servers itself. What the name server is doing differently here is sending a recursive query to the forwarder, expecting it to find the answer.
