class="left"> <div class="container description"> <p>In Millionen von Firmen und Privathaushalten verrichten DHCP Server so unproblematisch ihren Dienst, daß man sich Fragen kann warum ein Administrator da für noch eine Schulung braucht. Aber ohne funktionierenden DHCP-Server geht in der Mehrzahl der Unternehmensnetzwerke nichts mehr. Also macht sich der Administrator Gedanken darüber, wie er den Dienst ausfallsicher gestalten kann.</p> <p>Mit der Größe der Netzwerke wachsen auch die Anforderungen:</p> <ul> <li>zentralisierte Verwaltung in verteilten Netzen</li> <li>Sicherheit</li> <li>Zusammenspiel mit DNS-Servern</li> <li>Integration in die Netzwerküberwachung</li> <li>Zukunftssicherheit und IPv6</li> <li>...</li> </ul> <p>Fragen, auf die wir in dieser Schulung praxisnahe Antworten geben.</p> <p>Viele Netzwerke benutzen noch den ISC-DHCP Server. Dieser Server wurde im Oktober 2022 abgekündigt, der Kea-DHCP Server ist der offizielle Nachfolger des ISC-DHCP. In diesem Kurs lernen AdministratorInnen, wie bestehende ISC-DHCP Installationen auf Kea DHCP migriert werden können.</p> </div> <div class="container trainer"> <h3>Trainer und Dozenten</h3> <p>Der Trainer Carsten Strotmann arbeitet sein über 20 Jahren mit Linux/Unix und DNS in TCP/IP Netzen. Seit 2003 betreut er das Trainingsprogramm bei den DNS Spezialisten von Men & Mice und gibt weltweit Schulungen zu den Themen DNS, DNSSEC, DHCP und IPv6. Carsten arbeitet eng mit den Herstellern von DNS Software zusammen (ISC BIND, NLNetLabs NSD/unbound und Microsoft DNS) und ist aktiv in den RIPE und IETF DNS Arbeitsgruppen.</p> </div> <div class="container preconditions"> <h3>Voraussetzungen</h3> <p>Diese Schulung wendet sich an Systemadministratoren, die bereits ausgiebig Erfahrung mit Linux-Systemen haben. Während des Kurses wird praktisch ausschließlich das genannte Thema bearbeitet, die grundlegenden Mechanismen von Linux-Systemen werden als bekannt vorausgesetzt, ebenso wie fundierte Kenntnisse im Bereich IP-Netze wie sie z.B. in unserer <a href="/kurs/admin_grundlagen/">Linux Administration Grundlagen Schulung</a> und <a href="/kurs/fortgeschrittene/">Linux Administration Fortgeschrittenen Schulung</a> vermittelt werden.<p> </div> <div class="container content"> <h3>Inhalt</h3> <div class="content"> <h4>Einführung</h3> <ul> <li>DHCP Einführung</li> <li>DHCP-Konzepte für Netzwerke</li> <li>Einführung in die KEA-DHCP Software</li> </ul> <h4>Installation und Grundkonfiguration von KEA-DHCP</h3> <ul> <li>dynamische Pools</li> <li>statische Host-Reservierungen</li> <li>Standard- und benutzerdefinierte DHCP-Optionen</li> </ul> <h4>DHCPv6</h3> <ul> <li>Eine Einführung in das DHCPv6-Protokoll</li> <li>KEA-DHCP IPv6-Konfiguration</li> <li>DHCPv6 Präfix-Delegation und Rapid-Commit</li> </ul> <h4>KEA-DHCP-Hochverfügbarkeitsoptionen</h3> <ul> <li>Hot-Standby</li> <li>Load-Balancing</li> <li>Geteilte Datenbank</li> <li>Split- und Shared-Pools</li> <li>Backup-Server (Cold-Standby)</li> </ul> <h4>DHCP-Fehlerbehebung: Bewährte Verfahren und Tools</h3> <h4>Monitoring und DHCP-Statistik-Tools</h3> </div> </div> <div class="container times"> <h3>Kurszeiten</h3> <div class="content"> <p>Wer möchte, reist bis 22 Uhr am Vortag an und nutzt den Abend bereits zum Fachsimpeln am Kamin oder im Park.</p> <p>An Kurstagen gibt es bei uns ab 8 Uhr Frühstück.</p> <p> Unsere Kurse beginnen um 9 Uhr und enden um 18 Uhr. </p> <p>Neben den kleinen Pausen gibt es eine Stunde Mittagspause mit leckerem, frisch in unserer Küche zubereitetem Essen. </p> <p>Nach der Schulung anschließend Abendessen und Angebote für Fachsimpeln, Ausflüge uvm.
