File Transfer Environment Variables for the Clients

In the scp2 and sftp2 file transfer clients, if no file transfer profile is found, the default values for advice string parameters (Section Advice String) are taken from the following environment variables. These can be set in the /etc/profile file globally for all users and in the $HOME/.profile file for each user separately (or another corresponding file, depending on the users' shell):

SSH_SFT_ADVISOR_TRANSFER_MODE           (default: NULL)
SSH_SFT_ADVISOR_TRANSFER_FORMAT         (default: "line")
SSH_SFT_ADVISOR_RECORD_TRUNCATE         (default: "no")
SSH_SFT_ADVISOR_FILE_CODESET            (default: NULL)
SSH_SFT_ADVISOR_TRANSFER_CODESET        (default: NULL)
SSH_SFT_ADVISOR_TRANSLATE_TABLE         (default: NULL)
SSH_SFT_ADVISOR_TRANSLATE_DSN_TEMPLATES (default: NULL)
SSH_SFT_ADVISOR_FILE_LINE_DELIMITER     (default: NULL)
SSH_SFT_ADVISOR_TRANSFER_LINE_DELIMITER (default: NULL)
SSH_SFT_ADVISOR_FILE_TYPE               (default: "po" or "ps")
SSH_SFT_ADVISOR_FILE_ORG                (default: "vb")
SSH_SFT_ADVISOR_FILE_RECLEN             (default: "4096" or "80" or "1024")
SSH_SFT_ADVISOR_FILE_BLOCKLEN           (default: NULL)
SSH_SFT_ADVISOR_FILE_SIZE               (default: "1000000")
SSH_SFT_ADVISOR_DIRECTORY_SIZE          (default: "10")

The file transfer server does not use environment variables for default advice string parameter values.

The file transfer clients also use the following environment variables:

SSH_SFTP_OVERWRITE                      (default: "yes")
SSH_SFTP_SHOW_BYTE_COUNT                (default: "no")
SSH_SFTP_SMF_TYPE                       (default: NULL)

If variable SSH_SFTP_OVERWRITE is set to yes the default behavior is to overwrite existing files. If it is set to no the default behavior is not to overwrite existing files.

If variable SSH_SFTP_SHOW_BYTE_COUNT is set to yes the number of transferred bytes is shown after successful file transfer. Also the names of source and destination files are shown.

If variable SSH_SFTP_SMF_TYPE is set to TYPE119 file transfers create SMF records of type 119.

Furthermore, the sftp2 file transfer client uses the following environment variable:

SSH_SFTP_CMD_GETPUT_MODE                (default: NULL)

The SSH_SFTP_CMD_GETPUT_MODE variable specifies the FTP compatibility mode for get and put commands. If the variable is set to ftp the commands behave as in FTP client. For more information, see commands sget and sput.
