SFTP Sender Channel Connection Error...


i am working on scenario where PI needs to pick a file from the sftp server of our vendor. There are couple of vendors and i get same error in all the sender channels when i check communication channel monitoring.

In one of the sender channel i get as "Exception received: com.jcraft.jsch.JSchException: timeout: socket is not established" and

another sender channel error as "Exception received: com.jcraft.jsch.JSchException: Session.connect: Connection reset"

I even tried increasing the TimeOut from 30000msec to 90000msec but still i am getting the error. Moreover the channel in DEV is working fine but in Production system its throwing error.

    Hi Selva - For me it clearly seems like a network connectivity error.

    Make sure that the ports are open as it could be a firewall issue.

    You can try telnet to the SFTP server from PI system..

    How are you connecting? Key based? just with user ID&Passwords.

    Hi Selva,

    Please verify the following details:

    1) Private Key Password shouled be same as the password which is given while generating the key

    2) The user <SID>adm should have read access to the key root path

    3) Both extension of the public and private key should be recognized  by the PGP encryption module

    check this blog:

    Check the firewall, as mentioned by Hareesh too

    Hi Selva,

    The issue could be from the following.....

    1. firewall issue with the connection in your PI PRD system and SFTP server.

    2.Check if the folder permissions for your SFTP server are properly set, if you are archiving/deleting the file from SFTP server.

    Sometimes user level permissions are there and some times folder/file level permissions are set by SFTP admin.
