Suitable for:

This course covers the addressing schemes and hardware required in IP networks. It continues to cover the network services commonly in use on IP networks.

It can be taken after the Unix Administration course or with a reasonable level of Unix experience. The course will use Sun Solaris but could be applied to the majority of commercial Unix flavours with minor changes.

Throughout the course, delegates will gain extensive hands-on experience through the completion of practical exercises under the guidance of the course training consultant.

Objectives:

By the end of the course delegates will be able to:· 

• Troubleshoot network problems using the ISO 7 layer model as a reference.· 
• Design and Implement an IP network using Hubs, Switches and Routers.· 
• Configure IP addressing.· 
• Configure name resolution using DNS in a reliable and secure manner.· 
• Secure services on unix hosts.· 
• Configure and maintain dynamic assignment of network information using DHCP
