SFTPService.JSCH - SQUID

Sree Sirugudi <Sree.Sirugudi@xxxxxxxxxxx> · Mon, 9 Sep 2013 01:13:41 +0000

Dear Squid-users,

We are currently using Squid 2.7.STABLE8 and we have a requirement where we use IBM WebSphere Message broker version 8.0.1 ( ESB component) to do file transfers using IBM Inbuilt nodes such as” FileInput” and “FileOutput”. These nodes does
 have a SFTP option and we are trying to use the SFTP option on the “FileOutput” node on IBM message broker to send files via SQUID proxy to destination. According to IBM , these Inbuilt nodes are using JSCH for SFTP service.  We are currently struggling to
 understand whether SQUID 2.7 support “SFTPService.JSCH” or not?

Would appreciate if you can provide any advice on this issue. I have also attached a bit of trace file where error occurs on doing SFTP from IBM message broker to SQUID.

Error Description :
SFTPService.open 'com.jcraft.jsch.JSchException: Session.connect: java.net.SocketException: Software caused connection abort: recv failed at com.jcraft.jsch.Session.connect
