Who is sending ICMP echos to our terminal gateway on it's old
address (128.16.9.3). It won't answer now, nor did it ever.

We are seeing a source at LINC.CIS.UPENN.EDU or UPENN-LINC.ARPA

Try 128.16.9.0, or 128.16.5.1 (our primary nameserver) if you
need a very remote echo host.

i am interested what you are doing.
