sftp connection issue

[JJohnson1605187926]

I'm using Talend studio Version: 7.1.1 Build id: 20181026_1147.

I am trying to get an sftp connection. It has the format sftp://xxx.xxx.net

I can connect to the sftp server using Filezilla and successfully send a file but when I use the Talend component with the same connection string, user/pwd I get a java unknown host exception.

Has anyone had similar issues ?

Hello,

Are you using tFtpConnection component and check out "SFTP Support" option? Could you please upload your component screenshot on community? Please mask your sensitive data.

I am using  tFtpConnection. I have tried with the "SFTP Support" checked and unchecked - doesn't seem to make a difference.

I get the java.net.UnknownHostException.

The connection details are correct because I can use them to connect using Filezilla from the same machine

The local JRE appears to be 1.8.0

very wll documented here

https://docs.oracle.com/javase/7/docs/api/java/net/UnknownHostException.html

It means a resolution (or reverse resolution) isse , but you tell that filezilla runs fine

=> Do you use a proxy server ? if you do , did you configure proxy server on studio ?

=> It can come from a certificate that is not supported by jsch mvn module, can you chec this point ? here is the list of certificates supported by jsch :

try to ping the host from your command line and check if it works or not.

Hello,

You can think of using tSystem component and fire commands to connect to sftp server.
