Configuring Telnet Access Mode for Component Discovery

Configuring Telnet Access Mode for Component Discovery

Telnet discovery lets you discover components in the CA Configuration Automation network. Telnet discovery has the following requirements:

• The ftpd daemon and Telnet must be running on the Grid Node server.
• An FTP client and Telnet must be available on the managed or target server that the FTP daemon uses.

When you initiate Telnet discovery, CA Configuration Automation runs the Discovery Job on the Grid Node server. The Grid Node server starts a sequence of Telnet communications with the managed server. Following a Telnet negotiation, a Telnet command uses FTP to copy Discovery scripts to the managed server. The Discovery commands use Telnet to run on the managed server. CA Configuration Automation captures the output in a file and copies it to the Grid Node server.

Follow these steps:

1. On the Servers tab under Management, click the Access Profile link.

   Note: As a best practice, make a copy of a predefined access profile before you modify it.

2. On the Access Profile page, click the Telnet link.
3. On the Details for Profile: Telnet page, select Access Mode and define values in the required fields.

   Notes:

   • The Connection Timeout value is important to the Telnet access mode and CA Configuration Automation sets it to a high value by default. CA Configuration Automation uses the Connection Timeout value to stop idle connections.
   • The Prompts field values locate and identify the prompts that CA Configuration Automation displays while establishing a Telnet session with the targeted server.

Modify CA Configuration Automation Configuration Properties for Telnet

You can modify the Telnet configuration properties.

Follow these steps:

1. Click the Administration link.
2. On the Properties page of the Configuration tab, click > to display the next properties page.
3. Edit the following cca group properties in the Value column:

   telnet.connection.retries

   Defines the number of times to retry the Telnet connection process if it fails during discovery.

   telnet.read.timeout_secs

   Defines the maximum time to wait to gather the results after issuing a command.

   telnet.read.byte_to_byte_delay_secs

   Defines the maximum time to wait for the next byte while reading the results. CA Configuration Automation uses this value only if Look for Prompts is not selected in the access profile.

Configure Grid Node Server Properties for FTP

You can configure Grid Node server properties for FTP.

Follow these steps:

1. Click the Administration link.
2. On the Configuration tab, click the Properties link.
3. On the Properties page of the Configuration tab, click > to display the next properties page.
4. Edit the following grid group properties in the Value column:

   ftp.password

   Defines the password that is associated with the specified ftp.account value.

   ftp.port

   Defines the port number on which the FTP Server listens.

   ftp.root
