connection closed on SFTP using CHROOT for IBMi

  • 1.  connection closed on SFTP using CHROOT for IBMi

    Posted Mon May 13, 2024 08:53 AM

    I was trying to setup an SFTP access for IBMi where my IBMi would be acting as the host and an SAP server would be acting as the client.

    I did all these steps given in this link. Note: I wanted to give restricted access to the SFTP client so I had to use CHROOT to create a 'jailed root' for the user profile using which the SFTP will be initiated. 

    Everything else works fine, but when I initiate the connection, the connection gets closed in 5-6 seconds. 

    Please see the screenshot below. Check the last line where you can see the message connection closed immediately after opening and SFTP connection.

    Note: The full access method given on this link works fine. But I'm trying to setup the 'jailed root' method using CHROOT which involves setting up of separate root folder for the sftpuser.

    All the steps that I followed are present on this link under the topic "restricted access method". 

    Could you please tell me what am I doing wrong?

    Regards,

    Ravi.

    Hello Ravisankar Pandian
    Verify that the SSH server configuration file contains a configuration similar to this.

    Match User user
    PasswordAuthentication no
      ForceCommand internal-sftp
      ChrootDirectory /home/%u
      AllowTcpForwarding no
      X11Forwarding no

    Where user is the name of the user profile
