Exercise 30: Oak Pictures

You are the senior Linux administrator for a technical solutions company. One of your customers, Oak Pictures, has ordered a new SUSE Enterprise Linux Server 9 system to be configured at your location and then transported to them. Another administrator has already installed the operating system and added some applications that are standard for your company. You must now configure and tweak it.

The server will regularly run a number of unattended jobs as root. The appropriate configuration file should be edited to include entries for those processes shown in Table 2.4. All entries should run and write any output (standard or error) to /dev/null.

Table 2.4. Processes to Run Automatically

PROCESS	FREQUENCY
/usr/local/bin/oriontest.sh	Every 5 minutes starting on the hour
/usr/local/bin/suf.sh	Every 15 minutes, starting on the hour
/usr/local/bin/use.sh	Every 10 minutes, starting at five minutes past the hour
/usr/local/bin/orionrestart.sh	6:30 in the morning on Sunday, Tuesday, Thursday, and Saturday

You also need to configure the system according to the settings listed in Table 2.5.

Table 2.5. System Configuration Settings and Changes

ENTITY	NEW VALUE
Newly Created Files	All newly created files should have default permissions on them set to rw-rw-r--.
/home/jackson	The owner on all files beneath this directory should be changed from jackson to syed. Additionally, the group associated with all files beneath this directory should be changed from users to root.
/bin/zcat	Create a link to this file in the home directory of the root user. The name of the link should be viewer.
Users	Add two new users to the system: wintel and omni. The UID of wintel should be 1010 and of omni 1011. The passwords settings for each account should be such that they must be changed in 90 days. Additionally, all passwords should be in the /etc/shadow file as opposed to /etc/passwd.
Initial Runlevel	Set the intial runlevel of the system to the custom setting of 4.
Static IP Address Configuration	Use an IP address of 192.168.10.7, a subnet mask of 255.255.255.0, and a default router address of 192.168.10.101.
