Question: How much of TCP/IP is awake and functioning when the iSeries is rebooted in manual mode and stopped at DST (Dedicated Service Tools)? Answer: None. When you are in DST from a manual boot, only the SLIC has started. OS/400 is not up yet. There is a "short" TCP/IP stack that is loaded at that point, but only to support Operations Console functions. There is no way the iSeries was answering FTP/SMTP requests while in DST mode. If you completed the IPL to OS/400, then TCP/IP will start when QSYSWRK starts. Sometime in V5R1 that was changed to automatically start instead of needing to put it in the start up program. Even in an OS/400 restricted state TCP/IP is not active. Something else was triggering the FTP/SMTP events. Jim Oberholtzer Senior Solutions Architect Computech Resources, Inc.
