What's greatest possible distance between NFS server and client?

How far have you successfully maintained an NFS-mount of a directory
hierarchy from one machine to another over the Internet?  I thought I heard
rumors of somebody mounting an American disk in England, or some such.

What is the lag-time between packets when you begin to have problems with
such a thing?  Would there be a difference between PC-NFS and NFS on a UNIX

How slow a connection is the slowest someone has maintained an NFS link for
long periods (e.g., 8am - 5pm)?  Won't NFS re-connect itself if it looses
connection for a while?

Thanks for your experiences.

What's greatest possible distance between NFS server and client?

I've mounted a disk in Palo Alto across our portion of the internet (firewalled)
without too many problems. It is VERY SLLLOOOOOOWWWWWWWWWWW ! Also Sun apps such
as File Manager get a bit upset with the delay, but it is usable. It will
automatically reconnect when the net is slow.

1. Down 'Solaris' NFS Server hangs 'Solaris' Client

    I have a mix of Solaris 2.5.1 boxes and IRIX 5.2,5.3 & 6.2 boxes on my
    network.  When a Solaris NFS server goes down, my other Solaris clients
    hang on new logins waiting for the server to come backup up, BUT the
    IRIX boxes let users login with no problems.

    The Solaris and Irix boxes mount using the following options.


    We played with the automount program, but Solaris clients still hang.

    Any ideas?
