   I have two computers talking to each other using tcp. I then add another 
   computer talking to the first computer. While using send() I get the 
   error EFAULT while trying to send data to the first computer. The unix
   function perror translates this error as Bad address. Has someone else
   encountered this error? Is this an error on the sending machine or the
   receiving machine?

From send(2):

     ...

     [EFAULT]            An invalid user space address was speci-
                         fied for a parameter.

Since the only address passed into send() is the message pointer,
presumably you are either (a) passing in an invalid address for that
pointer, or (b) passing in a length that is too large and that causes
the kernel to fall off the end of your valid address space while
reading the message.
