WS_FTP(12.6) fails to transfer large file to SFTP Server from Apache.

Hi, We are using 12.6 WS_FTP to transfer files over SSH. smaller files (few bytes) get transferred to the server fine. But whenever we transfer few MB file size, apache server throws an error saying "

 

Bad length (100028) for cmd=SSH_MSG_CHANNEL_DATA - max. allowed=100000

 

WS_FTP is always sending 28 bytes extra. Is this a bug or any issue with our settings?

 

Thanks!!

      Yes, it was a problem with apache sftp client. We upgraded to latest version and it fixed the issue.

        In our case its the WS_FTP is the client and apache is the server. What was the client you used ?

      • Yogesh More (Customer)

        Ok.. it was other way round for us.

        What version of apache are you using?

        Latest 2.92. I bumped up the packet size to no avail. WS FTP client always sending 28 bytes more than the limit. Wondering if its tunneled or has some extension specific implementation bug on WS FTP.
