Hello,

As you all said, first am not able to ping the server itself. Should i further check for the authorizations or is it enough as am not able to ping.

[Former Member · Accepted solution]

hmmm. not necessary... may be server has ping command disabled....

i you are using windows... goto command prompt (start menu --> run --> cmd .. press enter key)

there issue command as:

ftp <your server ip>

now see if an ftp connection is being established with the system... if it is ,, it would ask for user name and password...

do post back

good luck

Hi,

I think the username and password given by you may be wrong (or) the server you are trying to connect would'nt have get connected. So please check them,.........

Hi,

To ping he server, you don't need any User ID and Password if its FTP Host.

Please can you check with the Host details and the Port used for it. Or try to connect to the FTP server with Anonymous Login feature.

I hope the Host FTP server is properly configured and its working.

Thanks

Hi,

Upto my knowledge I think username and password are required for a FTP server connection, as we are connecting to a remote server without proper authorization we can't login and perform the tasks.

Hi,

The User ID and Password are required for any kind of Data transition only.

You don't need the user ID and Password to ping the FTP server. If the user is not able to ping then there is later to check for any authorizations. First need to chech with connectivity details.

Hi Anand,

This is absolutely based on service unavailable error. Better try your XI physical box to connect the FTP. If its not possible contact your network team, they want to allow this FTP IP to firewall.

Hi ,

This error seems FTP Connection error, Check ur FTP Server its properly working or not and check the server name parameters in the adapter.

Dear Anand Krishna,

If the connection setting in Receiver Communication Channel to FTP are fine then there shouldn't be any problem.

Plz double check you connection parameters and authorization details to FTP.

As our friend told plz try to connect the FTP:// server from your browser.

Hi,

Possible Reasons

Either another application or another running instance is using the GUI connection port.

Solution

If another running instance is using the port , use this instance or stop it.

Try to stop and activate the File Adapter. Even in RWB you can stop the Communication channel and refresh it. This will solve the problem

Thanks

Hello

according to your problem there is no connection or some network problem as your FTP could be not be reached by sap .

surely there is a connection problem for FTP.

as the connection is established your problem will be resolved.
