• Encrypt TCP messages

    What is the best way to encrypt proprietary (non-XML) messages over a TCP socket from the iSeries? I am currently using IBM's QZRDSSRV API's to do the sends and receives and create the socket connections, but those API's don't support encryption.

    I am trying to learn about TCP statistics, especially Failed Connection Attempts. What value would indicate a high threshold? Also, what causes these errors to occur? Does this indicate an issue at the remote or local host? Or does it have to do with network bandwidth or lack of I/O, etc.? Thanks!
