  • Configure local storage using partitions and logical volumes
  • Create and configure file systems and file system attributes, such as permissions, encryption, access control lists, and network file systems
  • Deploy, configure, and maintain systems, including software installation, update, and core services
  • Manage users and groups, including use of a centralized directory for authentication
  • Manage security, including basic firewall and SELinux configuration

Thank you for the invitation.

 

  • Planning - cost, capacity planning, logistics (network design, server locations, where to install, wiring, IP address assignments, ...), network service providers (ISPs)
  • Preparing - temperature, humidity, electrical, fire, security, EIA/TIA wiring closet and cabling standards, UPS; Change management (preparing for any service changes)
  • Installing hardware - computers, terminals, disk drives, CD-ROMs, RAM, printers, NICs, cabling
  • Maintaining - regular preventative maintenance (daily, weekly, ...), boot and shutdown systems when needed, printers, backup media, tune systems for performance
  • Monitoring - printers, disk space, network, servers and workstations, performance, and security, and all log files regularly
  • Installing/upgrading/removing software - OS (kernel patches, new device drivers, ...), applications (new versions, DLLs, new configurations), documentation
  • Backups and archives
  • Configuring - kernel, networking software such as Samba, X Window, accounting, quotas, security, mail, news, time, web and other servers, ...
  • Trouble-shooting - network connections, services that don't start, faulty security, ...
  • Maintaining local documentation - new user's guide, policy and procedure documents (security plan, disaster recovery plan, administrative procedures, service request/bug report forms, ...), man pages for add-on software
  • Help and educate users - This includes working with your management (who sometimes needs the most help and education even if they don't think so), helping new users, experienced users, and yourself
  • Baselining - Generate system reports and correlate growth, changes over time.  (Use data to order supplies, spares, hardware and software upgrades in a timely manner, and to generate reports to management)
  • Problem solving - System administration is about solving problems, not memorizing how-to directions.  Often something won't work as it should.  What will you do then?
  • Know where to look for help - books, Netnews, man pages, on-line (www.tldp.org, docs.sun.com, www.redhat.com, ...)
