Telnet scenario: Telnet server configuration
The scenario depicts how an administrator configures a Telnet server, including objectives, prerequisites and assumptions, and configuration details.
Situation
Ken Harrison is the administrator for a new IBM® i environment for the fictitious company Culver Pharmaceuticals.
Objectives
He needs to configure the Telnet server to meet the following specifications:
- Allow up to 100 virtual devices to be created automatically.
- Always display the sign-on window.
- Restrict privileged users to specific devices.
- Limit each user to one device session.
Prerequisites and assumptions
This scenario makes the following assumptions:
- Culver Pharmaceuticals is running the IBM i operating system.
- TCP/IP is configured.
- Ken has *IOSYSCFG authority.
Configuration details
You can follow the steps to configure your Telnet server in System i® Navigator.
- Start the Telnet server:
- In System i Navigator, expand .
- In the right pane, in the Server Name column, locate Telnet.
- Confirm that Started appears in the Status column.
- If the server is not running, right-click Telnet and click Start.
- Set the number of virtual devices:
- Select .
- In the right pane, right-click Devices and select Properties.
- On the Devices System Values page, enable Pass-through devices and TELNET and set the Maximum number of devices to 100.
- Configure Telnet server properties:
- Select .
- In the right pane, right-click Telnet and select Properties.
Table 1. Telnet properties settings Click this tab... And ... System Sign-On Select: - Restrict privileged users to specific devices.
- Limit each user to one device session.
Remote Sign-On Specify the number of sign-on attempts allowed and the action to take if the maximum number of sign-on attempts is reached. Remote Select the Always display sign-on option for Use Telnet for remote sign-on. Time-Out Specify the action to take when jobs reach a time-out. You can also specify how long to give an operation before the job times out. You can specify information for both inactive jobs and disconnected jobs.
Note: These settings apply to all interactive devices and jobs on your system, not just Telnet. - Assign devices to subsystems.At the character-based interface, type:
ADDWSE SBSD(QINTER) WRKSTNTYPE(*ALL)
- Activate the QSYSWRK subsystem:
Check the status of the QSYSWRK subsystem:
- In the character-based interface, type
WRKSBS
(Work with Subsystems). - Verify that the following systems are displayed:
- QSYSWRK
- QINTER
- QSPL
If the QSYSWRK subsystem is not active, complete the following steps:
- In the character-based interface, type
STRSBS
(Start Subsystem). - Type QSYSWRK for the Subsystem description and QSYS for the Library, then press Enter.
- Repeat for Subsystem name QINTER with Library QSYS, and for Subsystem name QSPL with Library QSYS.
- In the character-based interface, type
- Create Telnet user profiles:
- Start System i Navigator and expand your system.
- Right-click Users and Groups and select New User.
- Enter the user name, description, and password.
- To specify a job description, click Jobs and enter the job description.
- Click OK.
- Verify that Telnet is working.
- Ken starts a 5250 emulation session and connects to the Telnet server.
