How to Discover Host Connection by Shell

This task includes the following steps:

1. Prerequisites - Set up protocol credentials

   This discovery uses the following protocols:

   • NTCMD protocol

   • SSH protocol

   • Telnet protocol

   • Universal Discovery protocol

   Note To discover Windows machines running an SSH server, set the Shell Command Separator attribute of the protocol to AutoDetect.

   For credential information, see Supported Protocols.

2. Prerequisites - Host Connection by Shell job

   When running the Host Connection by Shell job to discover Windows machines on which an SSH server running the F-Secure application is installed, you must make the following modifications to F-Secure:

   • Stop the F-Secure service completely.

   • Verify that there are no F-Secure leftover processes still running (fssh* processes).

   • Alter the following lines in the sshd2_config file. This is an F-Secure configuration file that resides in the F-Secure installation directory.

     • The DoubleBackspace setting should contain a no value, that is, DoubleBackspace no.

     • The EmulationType setting should contain a raw value, that is, EmulationType raw.

     • The EmulationTypeForCommands setting should contain a raw value, that is, EmulationTypeForCommands raw.

   • Save the altered sshd2_config file.

   • Restart the F-Secure service.

     Note The Data Flow Probe enables an SSH-based connection to remote Windows machines only if the remote SSH server providers are Open-SSH or F-Secure.

     For Open-SSH (that provides SSH servers for the Windows, UNIX, and Linux operating systems), DFM supports connections to Open-SSH only if the Open-SSH version is later than, or equal to, 3.7.1 (for any operating system).

3. Run the discovery

   Run the Host Connection by Shell job.

   For details on running jobs, refer to "Module/Job-Based Discovery" in the Data Flow Management section of the UCMDB Help.
