Hello everyone,
Today, We will learn how to connect to the SFTP server using our java application. We will be creating the session first and then will get the SFTP channel using the JSCH session.
I have also shown how you can authenticate the SFTP server with a private key.

Hi, could you please let me know about private and public key how it's working, I am facing big issue in project

Hi aaditya, Key security totally depends on settings that have been assigned to sftp server. This is totally optional. If your sftp server required a key then use it also during connecting to it. In this example, I have told about the private key that should be stored locally. Otherwise, if it helps, then ok but if not, you can share broadly on the issue you are facing. You can mail me a smartytechfizz@gmail.com

When error is connection refused : connect what should have to do? Plz reply fast... I use same code

@SmartyTechFizz 3 жыл бұрын

Hi Punam, There could only be 2 reasons for this error. Here's why? 1. The port you are trying to connect to is not open. 2. If the port is open but the service you are trying to connect at that port is not available. So, please check according to this.

@@punamchavan2752 Yes, for sftp it is port 22. So, now you have to check this port is open or not? If yes, then is this service running on this port.

The sftp server you are trying, is not able to connect or that server is not available to take any connections.

Hello Mam, I am actually connecting with private key instead of password. Please let me know how to change that code in your existing code.

Hi Divya, If you will watch this video, I have already explained that how you can use your private key to connect to sftp server. You can start from 3:00 and from there I have explained about it and at 4:40 I have mentioned the line of code which we can use. Please refer to this. If you will still face any issue, then let me know.
