Administering Red Hat Linux - Part III

The Administering Red Hat Linux - Part III course is designed for System Administrators and Programmers and other technical IT staff who need to acquire knowledge of the key networking, security and scripting tasks required to administer a Linux system.This course will teach many of the extra necessary skills required, over and above the Red Hat Certified System Administrator (RHCSA) exam requirements, to enable the delegate to work towards achieving the Red Hat Certified Engineer (RHCE) certification. Courses covering the topics required for RHCSA certification, which are also a requirement of RHCE certification, are covered on the Administering Red Hat Linux - Part I & Part II courses.The course assumes administration knowledge of the Red Hat Linux operating system to the level covered in the Administering Red Hat Linux - Part I & Part II courses.On completion of this Administering Red Hat Linux - Part III course the delegate will have gained practical experience of networking, securing and scripting on a Red Hat Linux system.The delegate will also gain the essential knowledge required to study towards taking the official Red Hat Certified Engineer (RHCE) certification.Administering Red Hat Linux - Part III Training CourseCourse Contents - DAY 1Course IntroductionAdministration and Course MaterialsCourse Structure and AgendaDelegate and Trainer IntroductionsSession 1: Administering a Virtual EnvironmentRevision of the virtualised environmentCreating a Network BridgeConfiguring the Firewall for a Network BridgeConfiguring a New KVM Virtual NetworkExerciseSession 2: Further Software ManagementThe Yellow Dog Update, Modifier Tool (YUM)Creating a YUM repositoryConfiguring YUM pluginsUnderstand the design of a packageBuild a simple packageExerciseSession 3: File Security and IntegritySystem SecurityExtended PermissionsGPGWhy encrypt data and verify the senderKey pairs and managementUsing Digital signaturesChecking and repairing file systemsExerciseSession 4: Network ManagementRouting under LinuxIPROUTE suite of programsConfiguring network cards and RoutingConfiguring the system as a GatewayIPV6 Addressing OverviewNetwork tools :ethereal, tethereal, tcpdump, netstat, wireshark,etcConfigure Ethernet BondingExerciseAdministering Red Hat Linux - Part III Training CourseCourse Contents - DAY 2Session 5: Securing Networks: FirewallsNetfilter - iptablesPacket Filtering using iptablesRule TargetsBasic Rules and their OperationConnection TrackingFirewalls with Virtual Machine BridgesDebugging Route ProblemsSource and Destination NAT ConfigurationRed Hat supplied tools for iptables configurationExerciseSession 6: DNSThe DNS/BIND system under Red Hat LinuxName Server HierarchySetting up DNSMaster/Slave ZonesReverse lookup ZonesRecord types and their syntaxName Daemon Control Utility (rndc)Address Match Lists (acl)Configuring a Caching Only Name ServerDNS in a chroot environmentTesting a DNS serverExerciseSession 7: Centralised and Secure StorageWhat is ISCSISetting up ISCSI Target and InitiatorAccessing Centralised StorageEncrypting file systemsAccessing encrypted file systemsExerciseSession 8: Configuring Network Time ProtocolStratum LevelsChoosing a time sourceConfiguring the ntp daemonNTP rolesSetting up an NTP Server and ClientDirect or Broadcast PollingAllowing NTP connectionsSyncing considerationsExerciseAdministering Red Hat Linux - Part III Training CourseCourse Contents - DAY 3Session 9: Sharing Files across the NetworkConfigure file sharing using NFSNFS commandsAutomounterIntroduction to CIFS(SAMBA)Configure file sharing between hosts with CIFSUsing Konqueror and Gnome to access sharesConfiguring an FTP serverAnonymous usersControlling access to the FTP serverUsing the sftp commandExercise Session 10: Advanced SecurityAdministrative PrivilegesConfigure sudo privilegesWhat is KerberosConfiguring a Kerberos 5 ServerSetting up the Kerberos ClientExerciseSession : 11 Basic Mail Server ConfigurationEmail ComponentsMail User, Mail Transport and Mail User AgentsConfiguring sendmail and postfixSendmail Configuration FilesSendmail Configuration with the m4 Macro LanguageManaging Virtual AddressesMacro DefinitionsSwitching to postfix, a sendmail replacementPostfix ConfigurationProcmail delivery agentConfiguring a null client using PostfixDovecot - POP and IMAP servicesExerciseSession 12: SSL and Web Service ConfigurationData Security and EncryptionPublic Key EncryptionConfiguring Virtual Hosts : Name And IP Based AccessDisplaying Apache Web Server Information and StatusDynamic Virtual hostsConfiguring HTTPSSigned CertificatesApache SSL Configuration FileHTTPS Virtual HostsExercise Administering Red Hat Linux - Part III Training CourseCourse Contents - DAY 4Session 13: Shell ScriptingWhat is a shell script?Creating and executing shell scriptsUser interactionCommand line argumentsDecision constructs using the 'if' statementCase statementLooping constructs: for/while/untilAutomating administrative tasksExerciseSession 14: Troubleshooting Un-Bootable SystemsTroubleshooting LinuxThe Rescue EnvironmentCommon boot problems and their resolutionBooting into GRUB (Maintenance Mode)Booting an un-bootable system into Recovery ModeBooting from USB devicesReinstalling the GRUB LoaderExercise
