I'm having troubles with setting up an NFS server. When I try to mount 
froma second NetBSD machine I get
	[hobbes] ~> mount_nfs kelvin:/home1 home1
	mount_nfs: rpcbind on server: RPC: Port mapper failure - RPC: Timed out
What's wrong?

I'm trying to export /home1 on kelvin. So on kelvin my rc.conf is set 
up as follows:
	mountd=YES
	mountd_flags=""
	rpcbind=YES
	nfs_server=YES
	nfsd_flags="-tun 8"
And I created /etc/exports on kelvin:
	#/etc/exports
	/home1  -mapall=nobody:nobody -ro hobbes

Thanks in advance,
Daniel
