Linux Post-Installation Tasks

•	“Set Up the Network Proxy”

•	“Ensure Proper Setup of yum”

•	“Ensure Proper Setup of SSH”

•	“Ensure Availability of Expect”

•	“Ensure Availability of net-snmp-utils”

•	“Ensure Local Browser Functionality”

▼	Set Up the Network Proxy

You can configure the server on which STA is installed to connect to the network directly or through a proxy server. The following procedure demonstrates configuring the network proxy settings with the GNOME windowing environment.

1.	From the GNOME desktop environment, select System > Preferences > Network Proxy.

2.	In the Network Proxy Preferences dialog box, specify the appropriate Proxy Configuration. Your specific settings will vary depending on your site requirements.

3.	Click Close.

4.	Proceed to “Ensure Proper Setup of yum”.

▼	Ensure Proper Setup of yum

Use this procedure to ensure that yum (Yellowdog Updater, Modified) is configured correctly on the STA server. Yum is used for managing software package updates.

1.	Change to the yum repository directory.

# cd /etc/yum.repos.d

2.	Download the latest yum repository file from the yum Website.

# wget http://public-yum.oracle.com/public-yum-el5.repo

Note – In the above command, the “l” in “el5” is lowercase L.

Note – Each time you run this command, any existing repository files are copied with an extension added to their filenames. Yum always uses the public-yum-el5.repo file with no extension.

3.	Open the repository file with a text editor.

# vi public-yum-el5.repo

4.	In the file, locate the entry that matches your Linux version, and enable it by setting `enabled=1`. Disable all other entries by setting `enabled=0`.

For example (OEL, version 5u6):

[ol5_u6_base]
name=Oracle Linux $releasever - U6 - $basearch - base
baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL5/6/base/$basearch/
gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-el5
gpgcheck=1
enabled=1

5.	Save and exit the file.

6.	Proceed to “Ensure Proper Setup of SSH”.

▼	Ensure Proper Setup of SSH

Use this procedure to ensure that SSH (secure shell) is set up correctly on the STA server. This will speed up transfers of STA database backups to a remote host.

1.	Open the SSH configuration file with a text editor.

# vi /etc/ssh/sshd_config

2.	Search for the AddressFamily and UseDNS entries. Modify them so they are NOT preceded with the comment character and their values are as follows:

AddressFamily inet
UseDNS no

3.	Save and exit the file.

4.	Restart the sshd daemon.

# service sshd restart

5.	Proceed to “Ensure Availability of Expect”.

▼	Ensure Availability of Expect

Use this procedure to install or update the Tcp Expect utilities on the STA server. The Expect utilities are required for the STA database backup and restore utilities. The Expect utilities are part of the standard Linux installation, so they should be available on the server as uninstalled packages.

1.	Use yum to check that the Tcl Expect utility packages are available on the server.

# yum search expect | grep -i ^expect

A listing of expect packages should appear.

2.	Install the Expect packages.

# yum install expect

Follow the prompts to install the packages.

Note – If you receive a message indicating that the expect package is already installed and at the latest version, no further action is necessary.

3.	Proceed to “Ensure Availability of net-snmp-utils”.

▼	Ensure Availability of net-snmp-utils

The net-snmp-utils package contains a utility (snmpget) useful for troubleshooting library SNMP connections. Use the following procedure to install this package.

Note – SNMP connection troubleshooting is described in the StorageTek Tape Analytics Configuration Guide.

1.	Use yum to check that the net-snmp-utils package is available on the server.

# yum search net-snmp-utils | grep -i ^net-snmp-utils

The package should be listed.

2.	Install the net-snmp-utils package.

# yum install net-snmp-utils

Follow the prompts to install the package.

Note – If you receive a message indicating that the net-snmp-utils package is already installed and at the latest version, no further action is necessary.

3.	Proceed to “Ensure Local Browser Functionality”.

▼	Ensure Local Browser Functionality

The following is optional. If you would like to run the STA application locally on the server, read the information in the following sections.

Note – Oracle does not recommend local access to the STA application due to server performance degradation.

Firefox and Adobe Flash Requirements

To access the STA application locally, you need to ensure you have the following installed:

•	Firefox 3.6

•	Flash 10 (minimum)

To install and verify Flash, see below.

▼	Install Flash

1.	Open Firefox.

Go to:

http://get.adobe.com/flashplayer.

3.	Select “.rpm for other Linux”.

4.	Click Download Now.

5.	Choose to open the file with Software Installer (default).

6.	Follow the prompts to install Flash.

7.	Restart Firefox.

8.	In the address line, enter the following URL:

about:plugins

The displayed plugin list should include Shockwave Flash.
