Re: Technical Observations on SATAN: Issue: VMS and TCP/IP

[pickerin () phoenix sas muohio edu (Robert A. Pickering Jr.)]

We Ran SATAN here against several of our Unix machines, all passed.  I 
then tried it agains one of our AXP/VMS workstations running Multinet.

It crashed.

After the machine came back up we tried it again.

It passed fine.

I did Heavy tests both times.  At first glance it appears that the AXP
just ran out of memory.
