Enhance DataPower Gateway to support GoAnywhere MINA SFTP Client connect to DataPower Gateway to get a file

Per Homeland security request, NYPD upgraded our GoAnywhere MFT from v7.9.1 to v7.10.1, which will use MINA SFTP client to connect to NYPD DataPower Gateway. The ftp command get and put work fine. But ftp command get failed.

I submitted an IBM PMR case TS022798349. IBM PMR support investigated with following result

"

I have received confirmation from our development team that Apache MINA SSHD 2.17.0 used by GoAnywhere MFT v7.10.1, is incompatible with the DataPower SFTP server.


This is because MINA sends multiple SSH_FXP_READ requests concurrently, while DataPower processes read requests sequentially. This can cause the connection to stall, eventually resulting in:


org.apache.sshd.common.SshException: Channel is being closed


Based on the observed behavior, this is an architectural interoperability limitation in the current DataPower SFTP server implementation.


-We would like to suggest the following workarounds:


  • Recommended: Switch GoAnywhere's SSH/SFTP Resource Provider to JSch.

  • Alternative: Configure MINA for sequential reads by adding:Dorg.apache.sshd.sftp.client.impl.AbstractSftpClient.async-read-buffers-count=1 and restart GoAnywhere.


-Additionally, you can submit a IBM Request For Enhancement (RFE) requesting DataPower support for pipelined/concurrent SSH_FXP_READ requests to be added in future fix packs. To submit a RFE, please go to The Integration ideas Portal at https://integration-development.ideas.aha.io. Complete and submit the RFE form and your request will be sent directly to the DataPower Product management team.

"

The workaround using SSH Resource Provider JSCH work, but homeland security require MINA.

The other workaround with Dorg.apache.sshd.sftp.client.impl.AbstractSftpClient.async-read-buffers-count=1 didn't work.


So I submit this RFE. We would like IBM make this work.


If you need any more information, I can be reached by email at wanneng.tang@nypd.org.


Thank you,
