PeSIT transfer sites

Unlike transfer sites for other transfer protocols, a PeSIT transfer site is also used for transfers initiated by the external PeSIT partner (considered client-initiated by SecureTransport). Only the Site Name is required in that case to define the partnership, so a PeSIT transfer site needs only a Site Name if it is not used for transfers initiated by the SecureTransport server on which it is defined.

For a PeSIT transfer site, the Site Name designates the destination for an incoming routed transfer. For more information, see Select a default PeSIT transfer site for routing.

The following table describes the PeSIT protocol options for a transfer site.

Field Description
Remote Partner Settings
 Host The host name or IP address of the remote server to connect to for file transfers. You cannot enter spaces-only values in this field. For more information, see Spaces in required fields.
Port The port on the remote server to be used for file transfers. You cannot enter spaces-only values in this field. For more information, see Spaces in required fields.
Network Zone

The network zone that defines the proxies to use for transfers through this site.

  • Select none to connect directly to the remote partner server.
  • Select any to allow SecureTransport to select the proxy connection using a network zone that enables an SOCKS5 proxy.
  • Select Default to use the default network zone proxy configuration. If no default is network zone is defined, transfers from this transfer site fail.
  • Select a specific network zone to use the proxy configuration defined for that zone.

For more information, see Specify TM Server communication ports and IP address for protocol servers on SecureTransport Edge.

Server Password Setting

To use a server password, select Use Password and type the password in the two fields. The password is required when a remote partner connects to this Server and password authentication is used. Valid values are strings of one to eight characters.

These fields are displayed when the Show Advanced Settings option is selected.

Partner Password Settings

To use a partner password, select Use Password and type the password in the field provided. The password is required when this Server connects to a remote partner. Valid values are strings of one to eight characters.

These fields are displayed when the Show Advanced Settings option is selected.

Transfer Settings

These fields are displayed when the Show Advanced Settings option is selected.

Compression

Enables horizontal online compression, vertical online compression, or both for transfers initiated by the SecureTransport Server. If the partner PeSIT server does not supports the selected compression, no compression is used for these transfers.

SecureTransport support all types of compression for transfers initiated by the partner PeSIT server.

Resync Allowed Enables dynamics resynchronization of exchanges during transfer, without interrupting the data exchange phase.
Checkpoint Interval

The maximum number of bytes in KB (equals 1024 bytes) that the sender may transmit between two consecutive checkpoints. Checkpoints are used to restart the transfer when required.

A value of zero indicates no checkpoints. A value of 65535 indicates an undefined interval.

Checkpoint Window

The greatest difference allowed between the number of the last checkpoint transmitted and the number of the last checkpoint acknowledged. When this number of checkpoints are not acknowledged, the sender suspends data transmission until it receives a checkpoint acknowledgment.

A value of zero indicates that no acknowledgments are required.

PeSIT Buffer size The size of the internal buffer for this transfer site in bytes. Valid values are 512 to 65535. A larger buffer improves performance. Specifies the maximum size of a PeSIT data element (PI 25). Should be greater than 800 bytes and less than 65535.
User Message Send

A string sent as PI 99 when the SecureTransport Server initiates a file transfer to the partner PeSIT server. The field may contain expressions. The tool tip lists valid expressions. If SecureTransport received the file using PeSIT, it retained the values of all the PeSIT PI codes as metadata and the PeSIT expression language variables contain those values. See also Expression Language, especially PeSIT variables.

The string that results from the evaluation of the expression must be at most 512 characters long.

User Message Receive

A string included in messages sent when the SecureTransport Server initiates a file transfer from the partner PeSIT server. The field may contain expressions.

The string that results from the evaluation of the expression must be at most 512 characters long.

Network Settings

These fields are displayed when the Show Advanced Settings option is selected.

Simultaneous transfers The maximum number of simultaneous transfers from this transfer site to remote PeSIT systems. A value of zero means no limit.
Parallel TCP connections The number of TCP connections to make for parallel TCP (pTCP) to accelerate transfers.
Parallel TCP package size The pTCP packet size in bytes.
Socket Send/Receive Buffer Size The size of the pTCP buffers in bytes. Specifies the TCP Socket maximum send and receive buffer size in bytes. This setting corresponds to SO_SNDBUF and SO_RCVBUF socket parameters.
pTCP connection retry count

The number of attempts SecureTransport makes for each TCP connection for pTCP.

When the value of the Host field is the address of load balancer for a remote PeSIT cluster, set this field to connections * (nodes - 1), where:

  • connections is the value of the Parallel TCP Connections field
  • nodes is the number of nodes in the remote PeSIT cluster

SecureTransport reties the connections until all connections are with the same PeSIT remote server.

It specifies the maximum times the SecureTransport will attempt to re-establish a connection with the remote server in case of "Unknown session" error.

This is useful in cases where the remote partner is a PeSIT cluster, the address in the transfer site represents the load balancer in front of the PeSIT cluster and the individual nodes behind the Load Balancer are not accessible.

In such environment, all connections have to arrive on the same partner node.

Depending on the load balancing configuration different number of retries or no retries (sticky session LB configuration) might be required.

Transfer Settings or Network Settings if the Show Advanced Settings option is selected
Use TLS/SSL Requires the use of TLS or SSL for communication with the partner server.
Verify partner's certificate

Verify the TSL/SSL certificate of the partner site.

This field is displayed when the Use TLS/SSL option is selected.

When selected, SecureTransport verifies whether the server certificate of the partner is chained to a trusted root using the algorithm specified in AgentServers.Ssl.trustAlgorithm server configuration parameter and the certificates imported in the Trusted CAs store.

Enable FIPS Transfer

Restrict PeSIT to use only FIPS 140-2 Level 1 certified cryptographic libraries.

The sender and the recipient must use the ciphers and ciphers suites listed in FIPS transfer mode. If the sender and the recipient do not provide the required ciphers and ciphers suites SecureTransport does not complete the transfer.

This field is displayed when the Use TLS/SSL option is selected.

Enable Transfer CFT compatible SSL Mode

Use a version of SSL that is compatible with Axway Transfer CFT. Legacy Transfer CFT are versions prior to 2.7.1 SP3 or 3.0.1

This field is displayed when the Use TLS/SSL option is selected.

 Login certificate The local certificate to use when connecting to the partner site.
Partner certificate The login certificate to use when authenticating the remote site.

The following sectiion provides how-to instructions for selecting a default PeSIT transfer site for routing:

Select a default PeSIT transfer site for routing

SecureTransport implements PeSIT routing as an intermediate partner by sending a received file to a PeSIT transfer site specified as the destination of the PeSIT transfer.

SecureTransport matches the specified destination to the names of the transfer sites for the account that receives the file. If a transfer site name matches, SecureTransport transfers the file to that site. No subscription is required. If no transfer site name matches and a default PeSIT transfer site is defined, SecureTransport transfers the file to that site.

If there is no default site, SecureTransport checks the Routing Mode value for the account. If it is Reject, the transfer is rejected before it starts. If it is Accept, the transfer is performed and the file is retained locally. If it is Ignore, a transfer that cannot be routed is ignored

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

  1. Select Accounts > User Accounts. The User Accounts page is displayed.
  2. Click the name of the account for which you want to set the default transfer site.
  3. Click the Transfer Site tab.
  4. Select the check box next to the name of the PeSIT transfer site to make the default.
  5. Click Set PeSIT Default.
  6. The default is indicated in the transfer site list.
