AT&T System V Release 4.0

[Juergen Kienhoefer]

We run the new AT&T System V Release 4.0 UNIX on a Mylex i486 EISA-bus workstation.
Unfortunately, things don't work out as they should. There are problems concerning
both, the hardware and the software. The problem we are fighting at the moment is
a communications problem on our local ethernet. Short connections work but as soon
as there are bridges in between we have a package loss (udp) of over 90% and tcp
gets no connection at all.
Other problems are:
  - ftp only writes files no longer than ca. 1k on the local machine
  - nfs-mount gets rpc autentication error
  - spray cannot connect to a portmapper on the other side (rpcbind)
  - ypbind is running verion 3 protocol and seems to be incompatible with the
    server running version 1 and 2

Is there anybody out there who has experienced similar effects? Please post or mail
more questions and answers on these subjects.
