FTP connection

Former Member — Mon, 18 Sep 2006 11:02:42 GMT

Hi all,

I am using the command

" CALL 'AB_RFC_X_SCRAMBLE_STRING'

ID 'SOURCE' FIELD PWD ID 'KEY' FIELD KEY

ID 'SCR' FIELD 'X' ID 'DESTINATION' FIELD PWD

ID 'DSTLEN' FIELD DSTLEN. "

for FTP connection.

When i key in my usrname and password it shows connection failed.

Does my password has to be always encrypted to make login.Can my present password(w/o encryption) keyed in work anyway.

Appreciate your ideas.

Thanks,

Stock.

Scrambling the pwd might not be the reason for the FTP connection to be failing.

There could be some other reason.

Find the RFC destination

IF sy-batch IS INITIAL.

l_rfc = 'SAPFTP'.

ELSE.

l_rfc = 'SAPFTPA'.

ENDIF.

Encrypt the password, Required for FTP connection

CALL 'AB_RFC_X_SCRAMBLE_STRING'

ID 'SOURCE' FIELD v_ftppwd

ID 'KEY' FIELD l_key

ID 'SCR' FIELD 'X'

ID 'DESTINATION' FIELD v_ftppwd

ID 'DSTLEN' FIELD l_dstlen.

Open the FTP connection

CALL FUNCTION 'FTP_CONNECT'

EXPORTING

Hi,

See the below code, Bold ones

REPORT ZFTPSAP LINE-SIZE 132.

DATA: BEGIN OF MTAB_DATA OCCURS 0,

LINE(132) TYPE C,

END OF MTAB_DATA.

DATA: MC_PASSWORD(20) TYPE C,

MI_KEY TYPE I VALUE 26101957,

MI_PWD_LEN TYPE I,

MI_HANDLE TYPE I.

START-OF-SELECTION.

*-- Your SAP-UNIX FTP password (case sensitive)

MC_PASSWORD = 'password'.

DESCRIBE FIELD MC_PASSWORD LENGTH MI_PWD_LEN.

*-- FTP_CONNECT requires an encrypted password to work

CALL 'AB_RFC_X_SCRAMBLE_STRING'

ID 'SOURCE' FIELD MC_PASSWORD ID 'KEY' FIELD MI_KEY

ID 'SCR' FIELD 'X' ID 'DESTINATION' FIELD MC_PASSWORD

ID 'DSTLEN' FIELD MI_PWD_LEN.

CALL FUNCTION 'FTP_CONNECT'

EXPORTING

*-- Your SAP-UNIX FTP user name (case sensitive)

USER = 'userid'

PASSWORD = MC_PASSWORD

*-- Your SAP-UNIX server host name (case sensitive)

HOST = 'unix-host'

RFC_DESTINATION = 'SAPFTP'

IMPORTING

HANDLE = MI_HANDLE

EXCEPTIONS

NOT_CONNECTED = 1

OTHERS = 2.

CHECK SY-SUBRC = 0.

CALL FUNCTION 'FTP_COMMAND'

EXPORTING

HANDLE = MI_HANDLE

COMMAND = 'dir'

TABLES

DATA = MTAB_DATA

EXCEPTIONS

TCPIP_ERROR = 1

COMMAND_ERROR = 2

DATA_ERROR = 3

OTHERS = 4.

IF SY-SUBRC = 0.

LOOP AT MTAB_DATA.

WRITE: / MTAB_DATA.

ENDLOOP.

ELSE.

do some error checking.

WRITE: / 'Error in FTP Command'.

ENDIF.

CALL FUNCTION 'FTP_DISCONNECT'

EXPORTING

HANDLE = MI_HANDLE

EXCEPTIONS

OTHERS = 1.

When you call 'AB_RFC_X_SCRAMBLE_STRING' the password will be encrypted and will be passed to the Function Module..
