LINUX TCP/IP Network Administration Crash Course with Computer Lab

$75 discount available to all attendees who are also registered for the System Admin course.

Class Description:

This comprehensive module provides instruction on TCP/IP, the native protocol of UNIX and the Internet, and Network Administration and configuration of the Linux platform to support network services. Students will learn how to use and administer a TCP/IP-based network. Topics include use of network commands, install and configure network hardware and software, establish remote login, remote command execution, file transfers between two systems, configure and use an anonymous FTP service, and install and configure the network file sharing(NFS). Students will also learn about network security, how to set up remote and network printing servers, firewalls and proxy servers, and if time permits, details about configuring Apache, DNS, NIS, Sendmail, SSH and Samba. Thoughout the course, a series of real-life lab exercises will be performed to verify proficiency in network administration and setup.

Prerequisite:

LINUX System Administration Crash Course with Computer Lab or equivalent UNIX/Linux System Administration experience. Students must have a good working knowledge of either Unix or Windows NT/2000/XP system administration and networking. It is recommended that students complete a course in Unix System Administration first. Most lab exercises will be performed under Unix, the platform of choice for the Internet, thus requiring attendees to be proficient enough with VI, Unix's visual editor, to be able to create and modify files. A working knowledge of TCP/IP end user utilities, such as telnet and ftp, would be an advantage.

Targeted for:

This is accelerated learning environment crash course for individuals wishing to learn how to configure LINUX to make use of common TCP/IP-based services, and communicate with a local LAN and/or the Internet. Includes discussions of FTP, RSH, SSH, NFS file sharing and RLP/Windows remote printer sharing. Also discussed is DNS, NIS, network security, firewalls, cable routers and everything you need to know about building a LINUX TCP/IP based LAN.

Course Objectives- What you will learn:

• TCP/IP Fundamentals as related to System Administrations Details
• Network Administration of Linux
• Managing Network Capabilities from inside Linux
• Service Management, Security, Advanced Topics

Handouts:

Copies of the course outline slides will be provided along with relevant handouts when appropriate.
