Re: ANTS' aping

["Phil Wang" <pywang@nortelnetworks.com>]

Norman,

I found an error in a configuration file for Accelar, "ping.routes". See
below for my correction.

True, they make confusion easily.

Yes. However, please make sure that you run JDK 1.1 on those Solaris
systems.

You would better to ask the MIT guys who made the ANTS. -:) 

That's why I wrote a number of REAMDEs and added comments in these
configuration files.
