This happens with random users trying to send files to my port (and yes, they do have access to the file are, and the file area work), but on a DCC Send, the eggdrop rejects the Send with the error message: "Invalid port"
I am using 1.6.7, and I had the dcc-pportrange set to that before I upgraded to 1.6.7, and I couldn't find that variable to set. I manually stuck it in the config file, and the same problem occurred. I have since deleted it and it is STILL doing the same thing.
