3 Secure FTP Setup I N T R O D U C T I O N This guide explains how to configure a secure FTP connection to BMO Bank of Montreal (BMO) to allow secured communication over the Internet. The FTP transmission service provides a high speed and reliable method of transmitting files between your PC/Server and BMO. The FTP with Secure Shell (SFTP) service uses standard File Transfer Protocol services. The connectivity is built upon the standard FTP with SSH protocol as defined by the Internet Engineering Task Force (IETF) SSH (or SECSH) working group. This service only supports SSH2 protocol, which is the most typical implementation of FTP with SSH. Note: SFTP connectivity supports SSH Public Key authentication and user ID/password authentication. It will first attempt SSH Public Key authentication, and if that fails, user ID/password authentication will be performed. For SSH2, either the RSA or DSA public key encryption algorithms can be used. Key lengths of 1024 (default) or 2048 are supported. This Service is provided in conjunction with GXS, Inc. B E F O R E Y O U S E T U P S / F T P The following items are required before you begin the setup: Obtain SFTP client software. Potentially any SFTP software that uses SSH2 protocol can be used for this service. See Appendix C for a list of tested SFTP software products. Please make sure to update your software to the latest supported version to avoid any possible compatibility issues. To use the FTP transmission service, you will need to have received the following from the BMO: 1. This user guide. 2. A SFTP questionnaire (Appendix A) - to be completed and returned to BMO. 3. A mailbox ID (same as FTP user ID) and password. a. If you selected the SSH Public Key Authentication, we will exchange public keys. 4. Your trading relationships (also know as mail slots). 5. Please review the Send and Receive sections of this document. Your BMO Implementation Specialist (IS) will provide you with your user number (mailbox id) and password as well as your trading relationships (mail slots). IS will also coordinate the exchange of public keys, if you selected Public key authentication PAGE 1 FOR ASSISTANCE, PLEASE CALL THE HELP DESK AT OR LOCAL

4 S E T T I N G U P F T P W I T H S S H Follow the instructions below to begin setting up SFTP. Note: if you have a firewall on your system, you will need to have the following ports open: Data port range 22 Install and setup your SFTP client software. Use default values in the setup with the following exceptions: Server address is sftp.tradinggrid.gxs.com Connection port 22 Enter your mailbox id (or userid) and password. NOTE: password is not required is you are using public key authentication Enter the applicable FTP commands for a session. Optional: If your SSH implementation requires the use of public keys, exchange public keys with us. Coordinate the exchange with your IS. PAGE 2 FOR ASSISTANCE, PLEASE CALL THE HELP DESK AT OR LOCAL

5 Sending Files A D D R E S S C O N S T R U C T I O N You can send files to us from your mailbox. In order to send files you must establish/confirm your mail slots with your IS. Depending on the number of services you have with us, you may have more than one inbound mail slot. The construction of the Send address for you is mailbox-send. Your mailbox is the same as the FTP user ID. BMO Receive addresses have been constructed using the application, document type and file encoding. This constructs your inbound mail slot to BMO. Your inbound mail slot consists of the following: o Application name provided by the IS; o Application document type provided by the IS; o File encoding provided by you when implementation was requested. Example: When you are sending an Electronic Transfer File (EFT) file to BMO, your inbound trading relationship will look as follows: DEFT-DEFT80-A where DEFT is the application name, DEFT80 is the document type, and A is file encoding (ASCII or E for EBCDIC). The above mail slot means that you can send 80 bytes EFT files in ASCII format. Please work with your IS to get details of all of your inbound mail slots. Refer to Appendix B for available file encodings. T O S E N D A F I L E In order to send files, FTP commands must be entered in your secure FTP software. Connect to SFTP site and login using mailbox-send: userid, where mailbox is your FTP userid. E.g. if your FTP userid is ADW12345, you would use ADW12345-SEND: IMPORTANT: Do not forget to use a colon ( : ) at the end of the userid. The second step is to indicate the receiving application or inbound mail slot where you need to send a file. In the previous example we used DEFT-DEFT80-A: as a mail slot. IS will provide you with a list of all inbound mail slots. You will need to perform a CD command, indicate Binary file transfer mode, and input an optional reference number: cd DEFT-DEFT-A:/*BIN/OPTIONALREF where DEFT-DEFT-A is your inbound mail slot, *BIN indicates Binary mode, and OPTIONALREF is your internal optional reference information. You are not required to input the reference information. Refer to the Address Construction section for details on address construction. PAGE 3 FOR ASSISTANCE, PLEASE CALL THE HELP DESK AT OR LOCAL

6 The final step to send a file is to use the PUT command. In the example below, a file named testfile.dat located in C:\temp directory will be used. This file will also be sent in binary mode. The command to send this file would appear as: PUT C:\temp\testfile.dat As a result there will be four commands Login using your mailbox-send: userid binary CD DEFT-DEFT-A:/*BIN/OPTIONALREF PUT C:\temp\testfile.dat In the example above, a file named testfile.dat located in C:\temp directory will be sent. This file will also be sent in binary mode. We do not require you to use any specific file names. The file will be processed based on the specified inbound mailslot (DEFT-DEFT-A) R E C E I P T F I L E Important: The following Receive address (or outbound mail slot) is provided in order for you to confirm whether the file was transmitted. The address has the following format: mailbox-receipt This address is used to receive a receipt, providing you with information on whether or not a Sent transaction was delivered successfully. These files are text-based and contain a single line without record terminators and should be readable on either Unix or Windows platforms. The receipt message indicates that BMO has received your file successfully and will convey it to the appropriate product (e.g., EFT). Note: to verify that your file has been successfully processed by the appropriate product, please check any output reports or files generated by the Bank, e.g. reports generated by the EFT system. Always verify such reports to ensure your files have been accepted and sucessfully processed by the Bank. PAGE 4 FOR ASSISTANCE, PLEASE CALL THE HELP DESK AT OR LOCAL

7 Receiving Files and Reports Any product files or reports that you expect to receive from any BMO service such as EFT, can be delivered electronically to you via the SFTP transmission service. O U T B O U N D ( F R O M B M O ) M A I L S L O T S BMO will send your reports and files to your mailbox. Depending on the number of services you have with us, you may have more than one outbound mail slot (also known as trading relationship). Your outbound mail slot consists of the following: Mailbox ID provided by the IS Application name provided by the IS Application document type provided by the IS File encoding provided by you when implementation was requested. BMO will send your files / reports to one of the outbound mail slots. For example, if you are set up to receive EFT reports or files your mail slot will look as follows: ADW12345-DEFT-EFTTESTSA-W where ADW12345 is your mailbox ID, DEFT is the application name, EFTTESTSA is the document type, and W is the file encoding. The above mail slot will be receiving reports from the EFT system in ASCII CRLF format. Refer to Appendix B for available file encodings. Please work with your IS to get details of all of your outbound mail slots (or trading relationships). L I S T I N G R E C E I V E D F I L E S The following section will describe commands that can be used to obtain a listing of messages in your inbox that corresponds to what you have received from BMO. Login to the SFTP site using your mailbox ID (e.g. ADW12345). You will need to execute the following change directory command to list files cd BMOCOM-SEND:%.%POLLABLE where BMOCOM-SEND: is BMO sending directory, POLLABLE means a file(s) that has not been previously downloaded. Once this command has been accepted by the service, you can then request a list of files based on this filter by using the command: dir Therefore to list a file for a specific mail slot you will need to perform the following commands: cd BMOCOM-SEND:%.%POLLABLE dir PAGE 5 FOR ASSISTANCE, PLEASE CALL THE HELP DESK AT OR LOCAL

8 Directory of /ADW12345/BMOCOM-SEND:%.%POLLABLE 5/4/2007 9:57:17 AM 4,602 %BMOCOM-SEND%ADW12345-DEFT-FILE- W%SFTP%POLLABLE%39fea10029b8b7ov000052i3 The above means there is one new file available. The file name is: F I L E N A M I N G C O N V E N T I O N File naming consists of several constants and variables. Values that are changing are bolded. For example, in the following: %BMOCOM-SEND%ADW12345-DEFT-FILE- W%SFTP%POLLABLE%39fea10029b8b7ov000052i3 %BMOCOM-SEND%ADW12345-DEFT-FILE- W%SFTP%POLLABLE%39fea10029b8b7ov000052i3 %BMOCOM-SEND% indicates the file was sent by the Bank. All file names sent by BMO will have this indicator. %ADW12345-DEFT-FILE-W% is your outbound mail slot. This value changes and depends on the number of outbound mail slots that you have. By using this value you can easily identify file types. %SFTP%POLLABLE% means the file has not been previously downloaded. All new files will have this in the file name. 39fea10029b8b7ov000052i3 is a unique reference number for the file. This reference number is different for each file. The above allows you to easily identify various files, report types, and file statuses. PAGE 6 FOR ASSISTANCE, PLEASE CALL THE HELP DESK AT OR LOCAL

9 R E C E I V I N G F I L E S The process of receiving content/files uses the same commands as described in the Listing Received Files section. However, in order to actually receive the messages instead of just listing them, the MGET or GET command must be used. The command used is: MGET * If no files are found, nothing will be downloaded. Login to SFTP site with your mailbox (FTP) id. cd BMOCOM-SEND:%.%POLLABLE dir (optional, if you want to list files first) binary (to switch to binary mode) MGET * (to download all new files). If you would like to download files again, you will need to slightly modify your commands. cd BMOCOM-SEND:%.%ACCEPTED dir (optional, if you want to list files first) binary MGET * (to download all available files). You will receive all previously downloaded files which are still available to download. Note: Once a file is downloaded, we will store it for 3 calendar days. If you need a file after 3 days, please contact our Cash Management Helpdesk. We will be glad to retransmit the file/s for you. PAGE 7 FOR ASSISTANCE, PLEASE CALL THE HELP DESK AT OR LOCAL

12 Appendix B - Definitions F I L E E N C O D I N G BMO supports several file encoding types. These are: W: Windows (ASCII machine) This encoding can be used in Outbound transmission from BMO ONLY. The default delimiter on the Windows platform is CR (Carriage Return) and Line Feed (LF). This means that the record terminators within the application files on the windows platform are CRLF. A: Unix (ASCII machine). The default delimiter on Unix platform is Line Feed (LF). This means that the record terminators within the application files on the Unix platform are LF. E: Mainframe (EBCDIC machine). There is no specific character as the record delimiter on mainframes (Unisys or IBM). The encoding of the data is EBCDIC. While sending and receiving files from the mainframes, no data conversion needs to be performed. O T H E R D E F I N I T I O N S Mailbox This is your user ID on the Secure FTP service. Mail slots (or trading relationships) Mail slots belong to a mailbox and are used to receive various Cash Management files and reports. BMO sends your files and reports to an appropriate mail slot. By using mail slots, you can easily identify the application to which your files and reports belong. PAGE 10 FOR ASSISTANCE, PLEASE CALL THE HELP DESK AT OR LOCAL
