 There is a fix for the SunOS 4 at the same site the main program is stored.
If you need the internet address email and I'll send it. SunOS version 4
uses a new version of the Network Interface Tap (NIT) and this is why
you are having problems. There is example code in the Sun manuals, I believe
it is under nit or etherfind. By the way, you have to have root privledge
to open the nit.
