</SPAN>The only problem you will have is that the <SPAN

number of sockets.<SPAN style="mso-spacerun: yes"> </SPAN>In kernel 2.4
that limit is 1024.<SPAN style="mso-spacerun: yes"> </SPAN>You can
either recompile the kernel to allow more, or you can use dpsm or jpolld as
your socket manager.<SPAN style="mso-spacerun: yes"> </SPAN>These socket
managers use the <SPAN class=GramE>poll(</SPAN>) function instead of select()
and are not subject to the limit.<SPAN style="mso-spacerun: yes">
</SPAN>You will however have to increase the number of file descriptors you
can have open per process.<SPAN style="mso-spacerun: yes"> </SPAN>This
can be done in a startup script that calls
ulimit.<o:p></o:p></SPAN></FONT></P>
