Redhat 9 tcpmounting

[randy]

 Hello

Does anyone know if rh9 supports tcp mounting

When I try I get the error
nfs server reported service unavailable: Address already in use

my servers
cat /etc/exports
/home/un/  192.168.0.214(insecure,rw)
/home/unt   nfs.krusty(insecure,rw)
/home/und    nfs.krusty(insecure,rw)

Does anyone know the option I would have to enable in the config when
building the kernel?

Also is there a enough performance gain to warrant recompiling the kernel?

Thanks for you help

Randy

Yes, but you need to recompile the kernel to get support for it.

CONFIG_NFSD_TCP=y but buyer beware.... FC1 will do this much better
plus its configured in by default....

Well it depends on how clean your networks is. If you're getting a bunch 
of retransmits
using UDP, then TCP should smooth things out (since TCP is much better 
at dealing
with retransmits that RPC over UDP), but if the traffic is already 
pretty smooth, then
performance may decrease a very small amount due to the TCP overhead.....
But the gains of using a smarter transport (i.e. TCP) outweighs  the very
small performance hit... imho...

Thanks for the response

What is  "FC1"

I am connect between two boxes with a crossover and gigabit nic cards

I a, trying to figure out ways to get rid of this error message on my
console about a host not responding.
I was thinking maybe tcp would help
