You and I know that. But it seems some PC/network folks don't fully grasp the concepts. When they say FTP, they visualize data flowing from here to there via an interactive dialog using the well known ports. When we say FTP, we refer to the hundreds of fully automated concurrent transfers using arbitrary ports.
The symptoms seen by the OP seemed to be consistent with some sort of constraint, such as limited port ranges in a network appliance. Such constraints may never be an issue if there were only PC's in the loop. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Shmuel Metz (Seymour J.)

You need multiple ports on a PC for the same reason that you do on z/OS. -- Shmuel (Seymour J.) Metz, SysProg and JOAT ISO position; see <http://patriot.net/~shmuel/resume/brief.html> We don't care.
