DATES:

1. Installing Linux
   • Install a prototypical minimally configured Linux server.
   • Customize the Linux installation for either a web or database server.
2. System Scripts
   • Modify the system start-up scripts to initiate the daemons provided by the instructor.
   • Use cron to schedule daily maintenance procedures.
3. Working with the Kernel
   • Optimize the Linux system by modifying the kernel configuration and recompiling the kernel.
   • Ascertain that the: 1- kernel has been successfully installed. 2- kernel is performing efficiciently.
4. NFS: Network File System
   • Setup and configure the NFS Server for the capability to be accessed by a designated group of users.
5. Cross-platform Integration
   • Configure Samba; it can be tested by accessing the disk using a MS Windows client.
   • Transfer files between the MS Windows and Linux systems.
6. Networking Concepts
   • Have the network drivers loaded automatically.
   • The network drivers are placed into the /etc/modprobe.conf file that the modprobe application can load the drivers into the kernel as required; the network drivers are normally loaded by starting the network service.
   • Edit the parameters to adjustment the configuration files for each device.
   • Change the initialization scripts for all of the networking devices located in the /etc/sysconfig/network-scripts directory.
7. System Security
   • Modify the PAM policy file located in /etc/pam.conf; it contains all the PAM policies for a system.
   • A Linux system can have an alternate configuration mechanism.
   • A firewall script can be designed to separate and secure the private network (eth1) from the Internet traffic (ppp0); while simultaneously providing flexibility for the internal network. Code and test a firewall script.
8. Implementing Mail Services
   • The configuration files for sendmail need to be backed up before any changes are made to them.
   • Configure sendmail to permit internal e-mail; do not allow external e-mails.
   • Allow incoming e-mails to be redirected to other local accounts.
9. Apache Web Server
   • Start the Apache web server; ensure that the server is working properly by running a simple command.
   • Given a new website provided by the instructor, setup a virtual home page.
   • Setup public HTML folders with the appropriate permissions required for the server to access and serve the pages.
   • Implement DNS. Indicate to the system resolver which name servers are to be used; this information is stored in the /etc/resolv.conf file.
   • Configure the named DNS daemon to only allow queries from the local server and internal network hosts.
10. Implementing DHCP
    • Configure a DHCP server with /etc/dhcpd.conf with more than one subnet of IP addresses.
    • The parameters specified above the "subnet" declaration are global parameters; they are applied to all subnet declarations.
    • The parameters inside each subnet override the global parameters.
11. Network Services
    • Install and start the FTP server.
    • Display a custom welcome banner which is to be presented to each new user connecting to the server.
    • Do not allow anonymous users full download access.
12. Troubleshooting Linux
    • The instructor will configure several scenarios; students will have to identify problems, determine which modules are associated with the problem, and resolve the problem.
