<br><tt><font size=2>Its interesting you say that, I didn't spend a lot
of time looking into the block sizes (just dug in and had a play with them),
but from the man page:</font></tt>
<br>
<br><tt><font size=2>
"If an rsize value is not specified, or if the
specified rsize value is larger than the maximum that either client
or server can support, the client and server negotiate the
largest rsize value that they can both support."</font></tt>
<br>
<br>
<br><tt><font size=2>So you may well have a point! Now I don't know
whether I increased, or decreased, the block size! Oh well... If
its not broke (which it isn't now)</font></tt>

<br><tt><font size=2>I guess I'm a member of the cult ;-) Cool, never
