ping it.

As silly as it sounds, when it gets to the point that it hangs, wait a
few seconds and then ping the Solaris box from the Linux box.

During the Jumpstart process Solaris send an ICMP packet to discover
the correct netmask, which Linux drops and never replies to.  If you
ping the Solaris box it gets the ICMP echo request (ie, the ping) and
seems happy with that as the answer to the earlier request and just
carries on happily.

But failing that, like I said before, run snoop (or tcpdump in your
case) and see what the last thing it does is...

  Scott.
