There are two exceptions: Hercules uses hardware assists to provide inter-processor consistency when emulating multiple CPUs on SMP host systems, and Hercules uses assembler assists to convert between little-endian and big-endian data on platforms where the operating system provides such services and on x86/ x86-64 processors.

Its developers ruled out using machine-specific assembly code to avoid problems with portability even though such code could significantly improve performance.

What follows is the procedure for IBM Personal Communications (PCOMM) 14.0 on Windows 10.The emulator is written almost entirely in C. USSTCP USSN Send out the default TN USS tableĪctivate the new TN3270 profile by issuing a MVS operator command, for example: VARY TCPIP,TN3270,OBEY,DSN=(TN3270)Ĭonfiguration of the terminal emulator on your workstation will vary depending on your workstation platform and emulator software. If a TSO session is closed, disconnect the userĪLLOWAPPL * Allow access to all applications. LINEMODEAPPL TSO Send all line-mode terminals directly to TSO. You can locate your TN3270 profile data set by searching for message EZZ6044I in the MVS console log, for example: EZZ6001I TN3270 SERVER STARTEDĮZZ6044I TN3270 PROFILE PROCESSING BEGINNING FOR FILEĮdit your TN3270 profile to add a definition for the TLS port (we chose port 992 in the AT-TLS profile, so use the same port number here): TelnetParms Standard SSL/TLS TELNET portĬonnType Secure Must be secure connectionĭEFAULTLUS Define LUs to be used for general users. Transfer this data set, converting from EBCDIC to ASCII to your workstation(s) where you run your terminal emulator. If RACLISTed, refresh the DIGTRING and DIGTCERT classes: SETROPTS RACLIST(DIGTCERT) REFRESHĮxport the TN3270 CA certificate to a data set, because the "client" terminal emulator will need this certificate in order to validate the TN3270 Server's certificate during SSL handshake processing: RACDCERT CERTAUTH EXPORT(LABEL('TN3270CA')) DSN('TN3270CA.CERT')

Generate a self-signed Certificate Authority (CA) certificate, which will be used to sign the TN3270 server's certificate. Issue a MVS operator command to start the PAGENT started task (and add it to your z/OS IPL automation): S PAGENT PAGENT EXEC PGM=PAGENT,REGION=0M,TIME=NOLIMIT, From TSO: RDEFINE STARTED PAGENT.* STDATA(USER(PAGENT) TRUSTED)ĭefine the PAGENT PROC in a system PROCLIB: //PAGENT PROC This user should have the following attributes:Īssociate the PAGENT started task with this user. If you don't have a PAGENT started task defined, create a user ID to associate with the PAGENT started task. If you have multiple TCPIP "stacks" or address spaces, you will need a "TcpImage" statement for each one (I won't deal with that case here).Ĭreate a configuration file for your TCP/IP stack, /etc/: TTLSConfig /etc/Ĭreate a TN3270 policy in a TTLS policy file, /etc/: TTLSRule TN3270 If you already have PAGENT operational, skip to the TTLS policy below, otherwise create a "root" configuration file, /etc/nf: LogLevel 255 But while you can certainly get carried away and create sophisticated policy constructs to control all aspects of IP communication with the mainframe platform, this article presents the "bare bones" approach that will get you started with PAGENT, sufficient to secure 3270 terminal emulator communications using AT-TLS. So, if you haven't embraced AT-TLS and the "Policy Agent" (PAGENT) in z/OS TCP/IP, now is the time! PAGENT has traditionally been regarded as somewhat complex and scary.

In the announcement for z/OS 2.4 in July 2019, IBM made it clear that native support for secure (SSL/TLS) sessions was going to be removed from the TN3270 server, FTP server and DCAS, in favour of AT-TLS.
