> Works just fine on one machine, i.e. select() does not return a '-1' which
lets it run through the rest of the code.  However, on other machines, it
does not work fine, -1 is always returned by select() with error of: Invalid
arguement

syntax of the posted code, or should I be looking at the creation of the
socket?
