I'm using a product called PowerSchool which is trying to send data to the FreeBSD server over SFTP. The service provide hosts it, so I can't do any debugging on the far end. What I know for sure is that any other program (FileZilla, command line sftp, etc.) will connect, authenticate, and view files just fine. This includes on-site and off-site traffic. PowerSchool, on the other hand, seems to have something go wrong during the authentication steps. When I tried to make one of these failed connections, I saw this in /var/log/messages: Aug 20 16:37:48 apps sshd[564]: error: PAM: authentication error for <<username>> from <<IP of PowerSchool>> Aug 20 16:37:48 apps sshd[564]: error: Received disconnect from <<IP of PowerSchool>>: 3: com.jcraft.jsch.JSchException: Auth cancel [preauth] Any idea what might be causing this? -- Jaime Kikpole Network Administrator Cairo-Durham Central School District Technical Support: help@cairodurham.org go.cairodurham.org/techtips -- This electronic message and any attachment(s) may contain confidential or legally privileged information protected by law from further disclosure and is intended only for the individual or entity identified above as the addressee.
