Manage the PeSIT server

PeSIT (Protocole d’Echanges pour un Systeme Interbancaire de Telecompensation, in English, Exchange Protocol for an Interbank Teleclearing System) is a file transfer protocol and framework developed by GSIT, the French interbank teleclearing system. SecureTransport implements the PeSIT version E non-SIT profile and supports the following features also supported by Axway Transfer CFT:

  • Mutual authentication by passwords
  • Send and receive
  • ASCII, EBCDIC and BINARY transfer modes
  • Fixed and variable record formats
  • Data compression during transfer
  • Transfer checkpoint and automatic restart
  • Flow control with sliding window
  • Integrity checking
  • Store and forward routing
  • pTCP protocol version 2

When a partner sends a file to SecureTransport using PeSIT, SecureTransport retains the values of many PeSIT PI codes with the file as metadata. The expression in the User Message Send field of a PeSIT transfer site can access the protocol identifier (PI) values. For details, see PeSIT transfer sites.

When SecureTransport routes a transferred file to a final PeSIT destination, SecureTransport includes both PI 61 and PI 62.

Because PeSIT transmissions can use SSL, SecureTransport include options to enable SSL.

To use PeSIT, specify the PeSIT settings for both the SecureTransport Edge and SecureTransport Server.

  1. Select one or more of the PeSIT transmission options:
    • Enable PeSIT over Plain Socket – PeSIT over TCP/IP without SSL
    • Enable PeSIT over Secured Socket – PeSIT over TCP/IP using TLS Comp
    • Enable PeSIT over Secured Socket (Legacy) – PeSIT over TCP/IP using TLS Legacy
      Note that PeSIT transfers between SecureTransport and other MFT clients over TLSv1 Legacy fail for certain ciphers. For more information, refer to Troubleshoot common problems.
    • Enable PeSIT over Secured Socket (Legacy § Comp) – PeSIT over TCP/IP with SSL/TLS. When SecureTransport is the server, it automatically detects the used SSL/TLS mode - Legacy or Comp, and sets the header length in the FPDU. Information about the detected mode is logged in the server log under Level > Debug.
    • Enable PeSIT over pTCP Plain Socket – PeSIT over parallel TCP/IP without SSL
    • Enable PeSIT over pTCP Secured Socket – PeSIT over parallel TCP/IP using SSL
  2. If you are not using the default port, type a port for each option you selected.
  3. If you enabled any SSL option, select an SSL Key Alias from the drop-down list.
  4. If you enabled any SSL option, to restrict PeSIT SSL connections to FIPS 140-2 Level 1 certified cryptographic libraries, select the Enable FIPS Transfer Mode check box. For more information, see FIPS transfer mode.
  5. Click Start.
Note To enable PeSIT without SSL (over plain socket), you must create an SSL encryption entry for a user class with SSL encryption optional. See Manage SSL access.
