The Troubleshooting  Practice problems come in three parts,each invoked by a separate command.The sections,commands,and number of problems in each section vary;therefore,run command count,to determine the number of problems for each troubleshooting command:

• For local: tslocal count
• For Services: tsservices count
• For Networking: tsnetwork count
• For Booting: tsboot count

Invoke the first local problem by running:

# tslocal 1

This command will set up the problem and will explain the goal.The goal will be stored in the file /etc/ts for later reference.Spend three to eight mintues trying to solve problem.

If you have not yet solved the problem,you may need a hint.Hints can be displayed by running tshint comand:

# tshint local 1 1

This will display the first hint for the first tslocal problem.Continue to invoke hints until you get enough information to solve the problem or until you run out of hints:

tshint local 1 2
tshint local 1 3
[  and so on ..  ]

The tshint command will tell you when you have reached the end of the hints.Again,do not spend more than five to ten additional minutes on this problem.

Whether or not you have solved the problem,run tslesson command:

# tslesson local 1

This command will tell the lessons intended to be taught by the problem.Some tslesson messages also give step-by-step instructions on how to approach a particular problem.

If,after reading the hints and the lesson,you are unable to solve the problem,call the instructor for assistance.

Proceed with the remaining problems in the same way. For example, tsnetwork 1 sets up the first network problem and tshint network 1 1 shows the first hint for the first network problem.
