 Summary of my experiences using PLIP on FreeBSD 2.2.5, with
 one 5x86-133 with 20MB RAM and a 486/25 with 4MB Contura laptop.
 
   - sometimes when using a fast and slow machine (eg.P100 and 486/25)
     the fast machine crashes when you do big transfers. I think it
     is due to buffer overruns on the slow machine side and the fast
     machine doesnt deal with this well. The work around is to get the
     slow machine to be the initiator end of any xfer, i.e. slow machine
     is saying "give me next block" or "here's the next block". Be warned
     things like ftp and rcp have different initiator ends.
   - NFS works (bearing in mind the above, use the old reduce the
     block size hack, although I never tried it). However, due to
     the way an RPC is implemented in FreeBSD, portmap/mountd attaches
     itself to the first network interface (for things like getting
     a hostname etc.) which is often lp0 (depends on kernel config). This
     is a pain because the RPC code can't handle a point to point
     interface (like PLPI or PPP) and you don't get a running mountd.
     Workaround is to add a static route use
 
     # to enable rpc to work with a PLIP network (rpc binds to the first
     # network interface it finds an lp0 is found v. early)
     static_routes="loop_lp0"
     route_loop_lp0="192.168.201.32 127.0.0.1 1"
