Ftp connection error

[#1]

Hello everybody,

I have a file to rfc scenario where i pick up files from a ftp server.

i also have a idoc to file and rfc to file scenario working with the same ftp.

so i have 3 CC working with the same ftp server, one picking up files and two puting files.

the ftp server has a firewall that locks you out if it detects a auspices behavior for 10 minuets,

so usualy i stop the CC for 10 minutes and than it works fine.

this are the errors i get:

"Error occurred while connecting to the FTP server "92.67.67.141:21": java.net.ConnectException: Connection timed out: connect"

and than i get an error:

"An error occurred while connecting to the FTP server '92.67.67.141:21'. The FTP server returned the following error message: 'com.sap.aii.adapter.file.ftp.FTPEx: 140,10,228)'. For details, contact your FTP server vendor"

but once or twice a day the CC stops working completely with the same errors.

i think that maybe the CC that picks up the files and the 2 CC puting files are working at the same time and creating the auspices behavior.

can anybody give input on what can i check or if someone encountered the same problem ?

TX

Hi Zevik,

Check Question no. 26 of sap note no. 821267. which says

This problem is either caused by incorrect firewall / packet filter settings or an incorrect configuration of the FTP server. Also make sure that you have correctly specified the host name / IP address and port of the FTP server.

Changing the connection type from 'active' to 'passive' (or vice versa) might additionally help to work around the incorrect firewall configuration.

Thanks!
