To collect events from IBM i systems, complete the following steps:

  1. If automatic updates are not enabled, download and install the most recent version of the IBM i DSM RPM on your JSA console.

  2. Configure your IBM i system to communicate with JSA.

  3. Add an IBM i log source on the JSA Console by using the following table to configure the parameters that are required to collect IBM i events:

    Service Type

    Secure File Transfer Protocol (SFTP)

Configuring IBM i to Integrate with JSA

You can integrate IBM i with JSA.

  1. From https://support.juniper.net/support/downloads/, download the following file:

    AJLIB.SAVF

  2. Copy the AJLIB.SAVF file to a computer or terminal that has FTP access to IBM i.
  3. Create a generic online SAVF file on the IBM i by typing the following command:

    CRTSAVF QGPL/SAVF

  4. Use FTP on the computer or terminal to replace the IBM i generic SAVF file with the AJLIB.SAVF file that you downloaded.

    Type the following commands:

    bin cd qgpl lcd c:\ put ajlib.savf savf quit

    If you are transferring your SAVF file from another IBM i system, send the file by placing the FTP sub-command mode BINARY before the GET or PUT statement.

  5. Restore the AJLIB file on IBM i by typing the following command:

    RSTLIB SAVLIB(AJLIB) DEV(*SAVF) SAVF(QGPL/AJLIB)

    AJLIB provides the mapping and data transfer support that is needed to send IBM i audit journal entries to JSA.

  6. Run AJLIB/SETUP

    The setup screen is used to configure AJLIB for FTP, SFTP, or a local path to receive the processed entries.

    The server user ID is required for FTP or SFTP, and a password is required for FTP. While FTP handles line delimiter conversions, you set the line feed to the expected value for the type of system that receives the SFTP transfers.

  7. If you want to use SFTP, run AJLIB/GENKEY.

    This command generates the SSH key pair that is required for SFTP authentication. If the key pair exists, it is not replaced. If you want to generate a new key pair, before you run this command, remove the existing key files from the /ajlib/.ssh directory.

  8. After you generate a key pair, use the following steps to enable the use of the key pair on the server:
    1. Copy the id_rsa.pub file from the /ajlib directory to the SSH server, and then install it in the appropriate folder.

    2. Ensure that the SSH server is added to the known_hosts file of the user profile that runs the AJLIB/AUDITJRN command.

  9. Use the appropriate user profile to do the following steps:
    1. Start a PASE (Portable Application Solutions Environment) shell by typing the following command:

      call qp2term

    2. Start a session with the SSH server by typing the following command:

      ssh -T <user>@<serveraddress>

    3. If prompted, accept the system key, and enter a password.

    4. Type exit, to close the SSH session.

    If you want to run these steps under a different IBM i profile than the one that runs the AJLIB/AUDITRN command, copy the .ssh directory and known_hosts file to the home directory of the profile that is used to run this command.

  10. To configure the filtering of specific entry types, use the AJLIB/SETENTTYP command.
  11. Set up the data collection start date and time for the audit journal library (AJLIB) by typing the following command:

    AJLIB/DATETIME

    If you start the audit journal collector, a failure message is sent to QSYSOPR.

    The setup function sets a default start date and time for data collection from the audit journal to 08:00:00 of the current day.

    To preserve your previous start date and time information from a previous installation, you must run AJLIB/DATETIME. Record the previous start date and time and type those values when you run AJLIB/SETUP. The start date and time must contain a valid date and time in the six character system date and system time format. The end date and time must be a valid date and time or left blank.

  12. Run AJLIB/AUDITJRN.

    The audit journal collection program starts and sends the records to your remote FTP server: If the transfer to the FTP server fails, a message is sent to QSYSOPR. The process for starting AJLIB/AUDITJRN is typically automated by an IBM i job Scheduler, which collects records periodically.

    If the FTP transfer is successful, the current date and time information is written into the start time for AJLIB/DATETIME to update the gather time, and the end time is set to blank. If the FTP transfer fails, the export file is erased and no updates are made to the gather date or time.

Manually Extracting Journal Entries for IBM i

You can run the DSPJRN command to extract journal entries for IBM i when an audit journal receiver chain is broken.

Run the ALJIB/DATETIME command to set the Start Date to *OUTF. This command forces the processing program to use the pre-built QTEMP/AUDITJRN outfile for parsing, instead of using the date time to extract journal entries. After you run the parsing program command AJLIB/AUDITJRN, the DATETIME is set to the new processing date.

  1. Log in to your IBM i system command-line interface (CLI).
  2. Run DSPJRN.

    The only changeable parameters in the following example are RCVRNG and ENTTYP. Do not change any other command parameters. Ensure that ENTTP matches the AJLIB/SETENTTYP command settings.

    DSPJRN JRN(QSYS/QAUDJRN) RCVRNG(AUDRCV0001 AUDRCV0003) JRNCDE((T)) ENTTYP(*ALL) OUTPUT(*OUTFILE) OUTFILFMT(*TYPE5) OUTFILE(QTEMP/AUDITJRN) ENTDTALEN(*VARLEN 16000 100)

  3. To set the Date Time to use outfile *OUTF support, run the AJLIB/DATETIME command.
    Figure 1: DSPJRN Start and End Times
    DSPJRN Start and End Times
  4. Run AJLIB/AUDITJRN.

The DATETIME is set to the next start date.

Pulling Data Using Log File Protocol

You can configure IBM i as the log source, and to use the log file protocol in JSA:

  1. To configure JSA to receive events from an IBM i system, you must select the IBM i option from the Log Source Type list.
  2. To configure the log file protocol for the IBM i DSM, you must select the Log File option from the Protocol Configuration list and define the location of your FTP server connection settings.Note

    If you are using the PowerTech Interact or LogAgent for System i software to collect CEF formatted syslog messages, you must select the Syslog option from the Protocol Configuration list.

  3. Use the log file protocol option that you select a secure protocol for transferring files, such as Secure File Transfer Protocol (SFTP).

Configuring Townsend Security Alliance LogAgent to Integrate with JSA

You can collect all audit logs and system events from Townsend Security Alliance LogAgent. You must configure Alliance LogAgent for the JSA LEEF and configure a destination that specifies JSA as the syslog server.

  1. Log in to your Townsend Security Alliance LogAgent appliance.
  2. Add the ALLSYL100 to your library list by typing the following command::
  3. To display the main menu select go symain.
  4. Select the option for Configuration
  5. Select Configure Alliance LogAgent and configure the following parameters.

    Parameter

    Description

    Interface version

    4=IBM JSA LEEF

    Transmit

    1=Yes

    Data queue control

    1=Yes

    Format

    4=IBM JSA LEEF

  6. From the configuration menu, select Work With TCP Clients.
  7. Select option 2 to change the SYSLOGD client and configure the following parameters.

    Parameter

    Description

    Status

    1=Active

    Autostart client

    1=Yes

    Remote IP address

    IP address of JSA

    Remote port number

    514

  8. From the Configuration menu, select Start LogAgent Subsystem. Events flow to JSA.

After TCP services start, consider automatically starting the Alliance LogAgent subsystem by modifying your IPL QSTRUP program to include the following statements:

/* START ALLIANCE LOGAGENT */ QSYS/STRSBS ALLSYL100/ALLSYL100 MONMSG MSGID(CPF0000)

For more information about installing and configuring for Independent Auxiliary Storage Pool operation, and more filter options for events, see your vendor documentation.
