About Linux System Adminstration

Duration: 2 Month(s)

This course is expected to take two months with each day having two training hours, you may also suggest to us how many hours your staff can have per day so as to detail a clearer period, which the course can take. The time will entirely depend on your suggestions. It can take lesser time if the number of hours per day is increased.

Course objectives:
  I. Install and configure a Linux server for mission-critical corporate services
  II. Manage user accounts, file systems, networking and system logs
  III. Integrate Linux within a multi-vendor environment
  IV. Configure Linux to provide network services
   V. Customize and upgrade the Linux kernel
  VI. Provide secure access to a Linux server

Course benefits:
Linux is a full-featured, robust UNIX operating system with a wealth of associated free software, capable of supporting high-performance network services. The quality of Linux software makes it a low-cost, reliable, supported computing platform appropriate for the corporate server environment. This comprehensive hands-on course provides the knowledge and skills you need to install, configure and administer a Linux server for mission-critical network services. You learn to install and upgrade key software components with the latest versions and enhance server security.

Who should attend?
This course is valuable for systems and network administrators, planners and integrators, and those interested in configuring and maintaining Linux servers. "UNIX/Linux Introduction," will be incorporated in the first days of the training as part one of the training. Some experience with TCP/IP is helpful but again if lacking, participants will be offered knowledge on the same.

Hands-on training
1. Participants will gain hands-on experience as they learn how to install, configure and administer a Linux server. Practical exercises include:
• Installing Linux
• Providing network file services in a Windows environment
• Building and configuring a new kernel
• Installing and configuring a Web server
• Setting up mail services
• Building a Linux print server for a multi-vendor environment
• Enabling secure network connections
• Implementing an FTP server
