Problem Tuning Maxsockets

[Company 2210]

I am trying to alter the number of maxsockets allocated from the default of
2022 to 8192 on a FreeBSD 4.8 box. However, when I try to perform this
operation via sysctl I'm informed the oid (kern.ipc.maxsockets) is read
only. Does this mean I need to recompile the kernel? I've tried 'options
MAXSOCKETS=8192' in a kernel recompile - but that was rejected by the inital
parse, so either the option is different to the sysctl name or their is
another way to do this? Could someone shed some light?

Thanks

Colin
