Eric, your original post said > We have no problem sending data from OS/390 to Linux at any matching MTU > value eg 1492. So, are you saying that you *do* have a problem with matching MTUs? Or it only works when OS/390 is the sender of the large data chunks? I.e. you can ftp in one direction but not the other? I would suggest a buffer trace on OS/390 to see the content of a failing CTC frame.
