(So are you a teacher or a student) :}

The Solaris box I think will be ok once I find out the problem with
getting through Linux (and just to keep things simple). Windoze??? I think
I may have eliminated that from the network. My girlfriend needs a DB and
think I convinced her to go with Oracle instead of Act2000 which I bought
her for x-mas (oooops).

Thanks,

John
