Use the Advanced tab to specify advanced properties for your listener. Not all properties apply to all protocols. By default, all advanced properties are displayed regardless of the protocols to which they apply. Use the Filter drop-drown menu to select a single protocol for which to display advanced properties. In addition, you can specify a string on which to filter the list of properties.
- Allow AS2 Identifiers in Actions
- When this property is not set, AS2 identifiers are not resolved by checking the commands in the actions. Consequently, AS2 Identifiers that are set in the actions will result in a run-time exception when sending and might result in an unknown trading partner relationship exception when receiving. Although this value is set to true by default, setting this property to false might help performance in environments with a large number of hosts and mailboxes.
- Archive Automatically After Maximum Receipts
- When the number of MDNs in the MDN directory (for example, as2\mdn or as3\mdn), the number of ACKs in the ACK directory (for example, ebXML\ack, RNIF\ack,AS4\receipt, or EBICS\ack), the number of EERPs in the EERP directory (for example, OFTP\eerp), or the number of DSNs in the DSN directory (for example, SMTP\dsn) exceeds this value (n), the VersaLex application automatically archives the oldest receipts into the archive subdirectory until n/2 receipts remain in the directory. By default, this value is set to 500.
- Archive File Maximum Size (mbytes)
- The maximum size of the receipt archive file stored in the archive subdirectory. When this file size is exceeded, a new, unique archive file is created.
- Async Resends
- Specifies the number of attempts that will be made to resend an asynchronous transaction that was not completed (that is, an AS2 MDN or ebXML ACK response has not been received asynchronously) within the specified timeout period.
- Async Timeout
- The maximum time (in minutes) that the Local Listener will wait for an asynchronous response before either resending the transaction (if AsyncResends > 0) or logging an error.
- Auto Accept Received Certificate (CEM)
- When selected, automatically accepts all partner certificates sent as part of an inbound Certificate Exchange Message (CEM) request. This setting can be overridden by selecting the Override Listener CEM Auto Accept Setting in the desired AS2 host(s). See Auto-accepting inbound EDIINT CEM requests for further information. By default, this property is not selected.
- Connection Timeout
- The amount of time (in seconds) allowed for each read operation on a connected port. In the Cleo VLTrader and Cleo Harmony applications, this also includes the amount of time allowed for data socket connections.
- Do Not Create Inbox Subdirectories For Multipart Payload Files
- Indicates, when a multipart payload message is received, whether the payload files should be placed in a date/time stamped subdirectory under the inbox.
- Email Local And Partner Certificate Expiration Notices
- When this field is populated, a daily email notification is sent to all recipients specified in this field when any local user or partner/CA certificates, that is, signing, encryption or packaging certificates (defined at the local listener level and/or those defined at the mailbox level) that have expired or will expire within the number of days configured in the Email Local And Partner Certificate Expiration Warning Days property. Additionally, if applicable, any SSL certificates for HTTPs, FTPs, OFTPs, SMTPs and/or SSH FTP (defined at the local listener level) that have or are about to expire will be included in this email notification. By default, this value is set to
%admin%, which points to the System Administrator Email Address defined in the Other tab in Configure System Options. See Other system options for more information. - Email Local And Partner Certificate Expiration Warning Days
- When the Email Local And Partner Certificate Expiration Notices property is configured with at least one email address, this property is used to define the number of days before a certificate is about to expire to trigger sending email warning notifications. By default, this value is set to 30.
- Email Recipient When Unable To Send Async AS2 MDN
- When this property is selected, the Local Listener will attempt to notify the intended recipient of an asynchronous MDN when it is unable to send it via HTTP or HTTP/s.
- FTP Idle Timeout
- The amount of time (in seconds) allowed between each FTP command.
Note: This is a Cleo VLTrader and Cleo Harmony option.
- FTP UTF8 Pathnames
- Indicates to support UTF8 pathnames. When enabled, UTF8 included in response to FEAT command.
Note: This is a Cleo VLTrader and Cleo Harmony option.
- Ignore RNIF Attachments
- Indicates whether attachments to received RNIF messages should be ignored. If selected, only the payload is extracted into the inbox and attachments are ignored.
- Incoming Connection Backlog Size
- This is the network socket backlog size per listening port. There is a handshake that the client and server go through to set up a connection, which allows the server to then accept the connection, and this backlog setting is the queue size for incoming connections that are in the process of being accepted. The larger the backlog size, the larger number of connections that can be in the process of being accepted at the same time. Connections that are not accepted result in a connection refused on the client side.
Note: This is a Cleo VLTrader and Cleo Harmony option.
- ISDN Controllers
- For those cases where is it is not possible through CAPI to ascertain the number of available controllers or the available controller number list is not sequential starting at 1. When necessary, property accepts comma-separated values, as well as dash-separated ranges.
- Local Bind Address
- When specified, all listening server ports for HTTP, FTP (Cleo VLTrader and Cleo Harmony applications only), OFTP, SMTP (Cleo VLTrader and Cleo Harmony applications only) and SSH FTP (Cleo VLTrader and Cleo Harmony applications only) will bind only to this address. By default, this field is blank designating that the application will bind its listening ports to all addresses available to the server.
- Log Received Message Details
- When this property is selected, additional information about the incoming message, i.e., whether it is signed, encrypted and compressed is logged.
- Maximum Allowed CEM Response Days
- The maximum number of days allowed for receiving a partner response when sending a set of certificates via Certificate Exchange Messaging (CEM) before the request is expired. By default, this value is set to 7 days.
Note: This is a Cleo VLTrader and Cleo Harmony option.
- Maximum Concurrent FTP Logins Per User
- The total number of logins allowed at any one time for any user. With the default value of 0, the number of concurrent connections per user will be limited to the Maximum Concurrent FTP Users mailbox setting.
Note: This is a Cleo VLTrader and Cleo Harmony option.
- Maximum Concurrent FTP Users
- The total number of active FTP users allowed at any one time.
Note: This is a Cleo VLTrader and Cleo Harmony option.
- Number Days Before Auto Delete Files In Local User Sent/Receivedbox
- If a sentbox and/or receivedbox is configured for local FTP, HTTP, or SSH FTP users, files not already deleted by the client will be automatically deleted after this many days. By default, this value is set to 7 days. A value of 0 turns off automatic deletion.
Note: This is a Cleo VLTrader and Cleo Harmony option.
- Number Of Passwords Before Repeats Allowed
- Specifies the number of previous passwords that cannot be used when changing the password for a local user.
- Omit Domain Names From Message IDs
- By default, message IDs for outbound messages are constructed to include the domain name (or machine name) from which it is being sent. Select this option if you do not want to include the name of your domain or machine as part of the message.
- Proxy Protocol: Regex To Match Load Balancer
- Specify a regex value for this property to cause the application to look for the Proxy Protocol header on all TCP traffic from IPs that match the specified value.
- Save Sent Receipt
- Specifies that a copy of all receipts sent to your trading partners will be saved in the sent folder (that is, AS2\mdn\sent, AS3\mdn\sent, ebXML\ack\sent, OFTP\eerp\sent, RNIF\ack\sent, SMTP\dsn\sent, EBICS\ack).
Note: This is a Cleo LexiCom-only option.Note: For AS2, within Cleo LexiCom, receipts are always retained in the AS2\mdn\sent folder for 24 hours to allow for possible retransmission of a previously sent MDN when a duplicate message is received.
- Send ‘200 OK’ For Empty AS2 Responses
- By default, when either no MDN is specified or an asynchronous MDN is requested and there is no content to return, a 204 No Content is returned by the Local Listener. Selecting this option returns a 200 OK response and 200 OK in the content of the response instead.
- SMTP Payload Resend Delay
- The time (in minutes) that the Local Listener will wait before either trying to resend an SMTP message to one or more multiple recipients that had previously failed to be sent (if SMTP Payload Resend Duration has not expired) or logging an error.
- SMTP Payload Resend Duration
- The maximum time (in minutes) that the Local Listener will continue to attempt to resend the original SMTP message when it had previously failed to be sent to one or more multiple recipients.
- SMTP Receive DSN Timeout
- The time (in minutes) that the Local Listener will wait for a delivery status notification before either resending the original message (if SMTP Payload Resend Duration has not expired) or logging an error.
Note: This is a Cleo VLTrader and Cleo Harmony option.
- SMTP Send DSN Retry Delay
- The time (in minutes) that the Local Listener will wait before either trying again to send a DSN that previously failed to be sent (if SMTP Send DSN Retry Duration has not expired) or logging an error.
Note: This is a Cleo VLTrader and Cleo Harmony option.
- SMTP Send DSN Retry Duration
- The maximum time (in minutes) that the Local Listener will retry sending a DSN.
- SSH FTP Ciper Pattern
- Regular expression (enclosed in brackets) that limits the set of cipher algorithms available for all listening SSH FTP server ports. The [List] button shows the resulting set of cipher algorithms for this property setting.
- SSH FTP Compression
- When this property is selected the SSH FTP server will enable supported compression algorithms. The default setting disables compression algorithms.
Note: This is a Cleo VLTrader and Cleo Harmony option.
- SSH FTP Key Exchange Pattern
- Regular expression (enclosed in brackets) that limits the key exchange algorithms available for all listening SSH FTP server ports. The List button shows the resulting set of key exchange algorithms for this property setting.
- SSH FTP MAC Pattern
- Regular expression (enclosed in brackets) that limits the set of MAC algorithms available for all listening SSH FTP server ports. The [List] button shows the resulting set of MAC algorithms for this property setting.
- SSH FTP Window Size
- Specifies the maximum number of received bytes allowed before a window adjustment is required. A large window size may significantly increase memory requirements if there are numerous large file transfers occurring concurrently. If VLProxy is used as a SSH FTP reverse proxy, this parameter will also affect VLProxy memory requirements. When receiving (client uses a PUT command), a typical SSHFTP Window Size setting would be equal to the largest expected file size or the default setting, whichever is greater. This setting will not normally affect sends since the receiver (the client) requires the majority of adjustments.
Note: This is a Cleo VLTrader and Cleo Harmony option.
- SSL Allow Legacy Renegotiation
- When this property is selected (default value), legacy renegotiation will be allowed. If this property is not selected, the extension described in RFC5746 will be used for renegotiation and any SSL clients must also support this extension. See RFC5746 for a description of the extension and the vulnerability it addresses.
- SSL Cipher Pattern
- Regular expression (enclosed in brackets) or wildcard expression that limits the set of SSL ciphers available for all listening secure server ports. SSL Cipher Pattern works in conjunction with certificates for all the applicable SSL servers, the SSL Ciphers setting, and the SSL Minimum Encryption Key Size setting. The List button shows the resulting set of ciphers for the applicable SSL server certificates and these three property settings.
- SSL Ciphers
- Specifies the list of ciphers available for all listening secure server ports (HTTP, OFTP, and, for Cleo VLTrader and Cleo Harmony applications, FTP and SMTP).
- Default Set (default value)
- All standard ciphers, excluding anonymous (DH_anon) and non-encrypting (NULL) ciphers.
- All Implemented
- All standard ciphers, including anonymous (DH_anon) and non-encrypting (NULL) ciphers.
- SSL Ignore Client Cipher Preference Order
- SSL Maximum Protocol Version
-
Specifies the maximum protocol version allowed for all listening secure server ports (HTTP, OFTP, and, for Cleo VLTrader and Cleo Harmony applications, FTP and SMTP). By default, this field is blank designating that the VersaLex application will select the most recent version (currently TLS 1.2).
SSL 3.0 - refer to RFC6101
TLS 1.0 (SSL 3.1) - refer to RFC2246
TLS 1.1 (SSL 3.2) - refer to RFC4346
TLS 1.2 (SSL 3.3) - refer to RFC5246
- SSL Minimum Encryption Key Size
- Specifies the minimum encryption key size allowed for all listening secure server ports (HTTP, OFTP, and, for Cleo VLTrader and Cleo Harmony application, FTP and SMTP). To prevent use of low- or medium-strength ciphers, change from the default value of 0 to 112, 128 or 256 (depending on the requirement). Note that if this value is set too high, all ciphers are filtered out causing the
No suitable cipher suites are enabledexception to occur. - SSL Minimum Protocol Version
- Specifies the minimum protocol version allowed for all listening secure server ports (HTTP, OFTP, and, for Cleo VLTrader and Cleo Harmony applications, FTP and SMTP). SSL 3.0 is the default value for compatibility with clients that do not support the more recent TLS versions 1.0, 1.1, and 1.2.
SSL 3.0 (default value) - refer to RFC6101
TLS 1.0 (SSL 3.1) - refer to RFC2246
TLS 1.1 (SSL 3.2) - refer to RFC4346
TLS 1.2 (SSL 3.3) - refer to RFC5246
- SSL Use Record Splitting
- Store Raw Received Message
- When this property is selected, raw received messages will be saved in the protocol's received directory (that is, AS2\received, AS3\received, AS4\sent+received,ebXML\sent+received, OFTP\received, RNIF\sent+received, or SMTP\received) under the VersaLex root path. These files may be useful in diagnosing problems, but it may be desirable to disable this setting when disk space needs to be conserved.
- Unknown Partner Message Action
- Determines the desired action to be taken when a message is received by an unknown or undefined trading partner.
