"mount system call failed" what's wrong?

Hi I have a network between two computers here. NAT works okay, but I can't share files between them.

I followed the wiki so here goes some configuration files (server first):

NAT.sh

#!/bin/bash
ifconfig eth0 192.168.0.1
iptables -t nat -I POSTROUTING -s 192.168.0.2 -d 0/0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward

/etc/hosts.allow

nfsd: 192.168.0.2/255.255.255.255
rpcbind: 192.168.0.2/255.255.255.255
mountd: 192.168.0.2/255.255.255.255

/etc/hosts.deny

ALL: ALL: DENY

connectNET.sh

/etc/rc.d/rpcbind start
/etc/rc.d/nfs-common start
/etc/rc.d/nfs-server start

Result....
:: Starting rpcbind                                                       [DONE] 
:: Starting rpc.statd daemon                                         [DONE] 
:: Mounting pipefs filesystem                                        [BUSY] 
:: Starting rpc.idmapd daemon                                     [DONE] 
:: Mounting nfsd filesystem                                           [DONE] 
:: Exporting all directories                                            [DONE] 
:: Starting rpc.nfsd daemon                                          [DONE] 
:: Starting rpc.mountd daemon                                     [DONE]

It's okay up to now, but when I type in the laptop:

mount 192.168.0.1:/root/Desktop/Teste /media/arquivos

it says: mount.nfs: mount system call failed.

I made a log with tcpdump of what happens in this mounting time. Here it goes:

the log of the desktop:

Thanks in advance!!

Re: "mount system call failed" what's wrong?

mount 192.168.0.1:/root/Desktop/Teste /media/arquivos

Try this instead:

mount -t nfs4 192.168.0.1:/ /media/arquivos

Re: "mount system call failed" what's wrong?

Sorry for the useless post but:

1) Arch forums are amazing, I use arch exclusively now, but I always go t google first, find a few bad results, go to the arch forums and find a solution rapidly, here is another case of that.

2) The names of the users in this post are "ILoveJapaneseGirls" and "IHateJapaneseDolphinKille"... that is amazing.
