1. Consider a file that has been given permissions 777 (owner-rwx,group-rwx,other-rwx), but returns a "permissions denied" when a user attempts to execute it. Explain the most likely reason.
It appears there are control lists on the server configured incorrectly.
2. You are given a scenario where a web server will need to access PDF documents are for customers to view their personal account information only. What mounting option would be:
* tmp : Temporary storage directories for malicious executables
* ext4 - An advanced level of the ext3 filesystem incorporating scalability and reliability enhancements for supporting large filesystems in keeping with increasing disk capacities and state-of-the-art feature requirements.
* ro – Read only will mount the file to the system for reading only.
3. Describe the process to create a quota hard limit of 2Gigs for a user
To configure the quota for a user, execute the command: edquota username. Using the vi editor to change the hard column from 0 200000. Save and quit vi.
4. How do you install quota in Fedora 14? yum install quota
5. Why do you get error about 'cannot remount filesystem mounted'?
Because you are already mounted on that file system and need to mount another filesystem.
6. What is the /etc/fstab file for?
Editing disk quota
7. What is the mount command? Explain.
Fedora 14 mount command is mount -o remount <DIR>
8. What is the
Design and Implementation for Business SQL Lab 4 Instructions: Procedural SQL Objective The objective of this lab is to teach you how to develop and use basic stored procedures and triggers the procedural language of your chosen DBMS. Prerequisites Before attempting this lab, it is best to read the textbook and lecture material covering the objectives listed above. While this lab shows you how to create and use these constructs in SQL, the lab does not explain in full the theory behind the…
2O Cellular Respiration Lab Report Introduction Cellular respiration is the breaking down of food molecules and converting them into energy. Glucose is oxidized as long as there is the presence of oxygen and if not, fermentation will begin to take place. All organisms, including plants and animals, go through cellular respiration. This process creates energy for the body to exert in the form of ATP. This lab is to test if peas go through cellular respiration before germination. Hypotheses Part I:…
Victoria Withers Lab 4: Histology Question: How do the different types of tissue in the body differ from one another? Hypothesis: I think that each type of tissue will have significant differences in structure and its own unique qualities compared to other tissue types. If the tissues are compared to one another, then they will each have their own unique qualities and differences in structure. I believe this because each type of tissue has a different function. With cells, the structure reflects…

Experiment 4 Post-Lab Behavior of Gases Introduction In this lab we were looking at the different Gas laws. Boyle’s Law and Charles’s Law, Boyle looked at the temperature vs. pressure and Charles looked at volume vs. temperature. With Boyle’s Law my hypothesis was that the pressure would go up if the temperature went up because when water is heated the molecules expand making the pressure greater. Charles’s Law when the pressure went up the volume went down. Some of the problems with this lab is you…

Isolation of Eugenol from Cloves by Steam Distillation and its Identification by Infrared Spectroscopy Eim A. Chemist CHEM 303 June 16, 2005 INTRODUCTION “Essential oils” are the volatile components associated with the aromas of many plants.1 In this experiment, the essential oil eugenol (the main component of oil of cloves) will be isolated from ground cloves using the technique of steam distillation, which is often used to isolate liquid natural products from plants.2 The principle of…
