This is part of an earlier thread about configuring routers using a
script.

I'd recommend using tcpwatch to debug the connection.  The router may
have sent an error message before closing the connection.  Remember that
the router software was designed for human interaction.  tcpwatch will
allow you to see both sides of the conversation.

You'll see in the earlier thread that I'd also recommend using tftp to
send most of the commands and limit the interactive telnet script to:
	logging on
	running tftp
	logging off
