Unix System Administration

Module 1: Introduction to Unix

• Unix history: AT&T Unix, BSD, and commercial Unix variants
• Unix vs Linux: philosophy, licensing, and key differences
• Unix variants: AIX, HP-UX, Solaris, and macOS
• Unix shell: sh, ksh, csh, and bash on Unix systems

Module 2: File System and Commands

• Unix file system hierarchy: /, /usr, /var, /etc, and /home
• Essential commands: ls, cp, mv, rm, find, and xargs
• File permissions: chmod, chown, ACLs on AIX and Solaris
• Archiving: tar, compress, gzip, and cpio on Unix

Module 3: Unix Process Management

• Process commands: ps, top, kill, nice, and renice
• Background processes: &, nohup, and job control
• Signals: SIGTERM, SIGKILL, SIGHUP, and signal handling
• cron: scheduling tasks with crontab on Unix systems

Module 4: User and Group Administration

• User management: useradd, usermod, and passwd on AIX/Solaris
• Group management: mkgroup, chgroup, and /etc/group
• PAM: pluggable authentication modules on Unix
• LDAP integration: connecting Unix authentication to directory services

Module 5: Storage on Unix

• AIX LVM: physical volumes, volume groups, and logical volumes
• Solaris ZFS: zpool, dataset, and snapshot management
• NFS: configuring NFS server and client on Unix
• SAN connectivity: HBA configuration and LUN mapping on Unix

Module 6: Unix Networking

• Network configuration: ifconfig and ipadm on AIX and Solaris
• Routing: route command and static routing configuration
• DNS client configuration: /etc/resolv.conf and nsswitch.conf
• SSH: key-based authentication and SSH hardening on Unix

Module 7: System Performance and Maintenance

• Performance tools: vmstat, iostat, sar, and topas on AIX
• Crash dumps: analysing system core dumps on Unix
• Patch management: AIX fix packs and Solaris pkg updates
• System logging: syslog, errpt on AIX, and fmadm on Solaris

Module 8: Capstone Project and Assessment

• Unix storage: LVM on AIX or ZFS on Solaris configuration exercise
• User management and PAM authentication configuration
• Performance monitoring and patch management project
• Final assessment and course certification

Experience in the Industry Learn from Unix system administrators who have managed AIX, Solaris, and HP-UX environments for banking, insurance, and manufacturing organisations running mission-critical workloads on enterprise Unix servers.

Backgrounds at the Top Our Unix administration trainers have worked at IBM, Oracle, and enterprise IT teams managing large Unix server estates where AIX and Solaris power core business applications.

Clear & Effective Teaching Unix file system, commands, permissions, process management, user administration, AIX LVM, Solaris ZFS, NFS, networking, performance tools, and patch management are explained with real Unix system administration examples.

Hands-On Learning Focus Students manage files and processes, administer users and groups, configure storage with LVM and ZFS, set up NFS, tune performance, and apply patches through structured hands-on Unix administration lab exercises.

Up-to-Date Knowledge Trainers keep content current with the latest IBM AIX and Oracle Solaris releases, Unix on Power systems, and evolving enterprise Unix system administration best practices.
