Make sure TCP extensions are off on both ends; you probably have > broken hardware somewhere in between which is lighting all the bits. The file is on BSD box 1. BSD box 1 has a modem on a serial port. BSD box 2 has another mode on a serial port. BSD box 2 dials BSD box 1, connects via SLIP. BSD box 2 attempts to transfer the File Of Death from BSD box 1. Note that the file can come from systems further away (BSD box 1 is a router), the transfer will still fail. Other traffic, including larger files, moves fine. This file stops after about 4M. > Terry Lambert -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
