WA1184 AIX Network Administration 1. TCP/IP Overview What Is TCP/IP? OSIRM TCP/IP and OSIRM TCP/IP, OSIRM, and IEEE 802 Topologies Hardware Address Internet Protocol IP Address Default IP Address Classes Subnet Masking Off-byte Boundary Subnet Mask Fragmentation and Reassembly IP Routing IP Header ICMP ARP TCP Vs. UDP UDP Header TCP Header TCP Handshake TCP Sliding Window Application Layer Protocols Network Terminology Summary 2. Dynamic Host Configuration Protocol Objectives Required Software Configuration of Adapters Interface Configuration SMIT Minimum Configuration Dead Gateway Detection SMIT Further Configuration ifconfig Command hostname Command /etc/hosts route Command netstat -rn /etc/resolv.conf ping Command netstat -in System Resource Controller SRC Commands TCP/IP Daemons inetd Daemon /etc/inetd.conf /etc/rc.tcpip Bootup Process for TCP/IP Review 3.PPP - Point to Point Protocol Objectives PPP Environment PPP Protocols PPP Server Configuration Steps Configure Server Serial Port Configure Server LCP Configure Interfaces Create user and password Start pppcontrold Check Interface Client Configuartion Create Client Serial Port Create Client LCP Configuration Create chatfile Start pppcontrold Execute pppattachd Check configuration Use Connection The Whole Picture Summary 4. DNS - Domain Name Service Objectives Name Resolution Domain Name Service Internet Structure Zone of Authority in-addr.arpa Domain DNS Server Types DNS or not DNS Default Name Resolution Hierarchy Change Default Hierarchy DNS Implementation Scenario Configure Master Steps Create /etc/named.conf Database creation shell scripts /var/named/dal.ibm.com /var/named/revip9.1.2 /var/named/revip127.0.0 /var/named/cache Create /etc/resolv.conf Start the named daemon Configured Master Server Configuring Slave Server Create /etc/named.conf Create local IP zone file Create /etc/resolv.conf Start named Configured Slave Server Configuring a Caching-only Server Forwarders Configuring Clients Maintaining the databases nslookup Troubleshooting Tool nslookup batch examples nslookup Interactive Example Summary 5.DHCP - Dynamic Host Configuration Protocol bootp Overview bootp Header dhcp - Dynamic Host Configuration Protocol dhcp Overview Some dhcp Additional parameters Configuration Example Configure dhcp Server Turn off bootp Edit /etc/dhcpsd.cnf Start the dhcpsd daemon Client Configuration Steps Turn off bootp Edit /etc/dhcpcd.ini Start dhcpcd daemon Configure Relay Agent dhcp and DNS Summary 6. NFS Overview Objectives Purpose of NFS NFS and the OSIRM How is NFS Heterogeneous How is NFS Transparent Statelessness Mounting Review Filesystem Remote Mounting Example Security Unix Authentication root Authentication NFS Daemons portmap mountd biod nfsd lock and statd Summary Review 7. NFS Configuration Objectives NFS Prerequisites Steps for Configuring Server Add a Path to the Exports List 1 Add a Path to the Exports List 2 exportfs Command /etc/rc.nfs Shell Script Add /etc/rc.nfs to /etc/inittab Steps for Configuring the Client Execute the Mount Command Create Predefined Mountpoints 1 Create Predefined Mountpoints 2 Mounting Options for NFS Mount using type option Controlling NFS Daemons Umounting Remote Mounts Summary Review
