Bom dia pessoal! O cenário é o seguinte: Tenho 02 servidores de teste rodando o freeXen, e quero efetuar uns testes mountando um compartilhamento do servidor 02 no servidor 01 via NFS.
O problema é que tudo está configurando, porem nao funciona... Ai vão os detalhes do servidor 02 (servidor NFS):
[root@xen2 /]# cat /etc/exports
/backup 10.140.48.164(rw,sync) 127.0.0.1(rw,sync) 10.140.49.244(rw,sync)

[root@xen2 /]# cat /etc/hosts.allow
#
# hosts.allow This file describes the names of the hosts which are
# allowed to use the local INET services, as decided
# by the '/usr/sbin/tcpd' server.
#

ALL:ALL
NSF: ALL

[root@xen2 /]# rpcinfo -p
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100003 4 udp 2049 nfs
100021 1 udp 53559 nlockmgr
100021 3 udp 53559 nlockmgr
100021 4 udp 53559 nlockmgr
100003 2 tcp 2049 nfs
100003 3 tcp 2049 nfs
100003 4 tcp 2049 nfs
100021 1 tcp 48873 nlockmgr
100021 3 tcp 48873 nlockmgr
100021 4 tcp 48873 nlockmgr
100005 1 udp 764 mountd
100005 1 tcp 767 mountd
100005 2 udp 764 mountd
100005 2 tcp 767 mountd
100005 3 udp 764 mountd
100005 3 tcp 767 mountd

O ESTRANHO é qu eno Netstat ele nao aparece:
[root@xen2 /]# netstat -putan

[root@xen2 /]# iptables -L

Quando mounto o compartilhamento no proprio servidor pelo localhost ele funciona, vejam:
[root@xen2 /]# mount 127.0.0.1:/backup /media -t nfs -v
mount: trying 127.0.0.1 prog 100003 vers 3 prot tcp port 2049
mount: trying 127.0.0.1 prog 100005 vers 3 prot udp port 764

Quanto troco o 127.0.0.1 pelo ip dele ele da Connection refused

Agora quando vou no Cient (XEN1) e tento mountar o seguinte ocorre:

[root@xen1 /]# mount 10.140.48.165:/backup /media -v
mount: no type was given - I'll assume nfs because of the colon
mount: Unable to connect to 10.140.48.165:111, errno 111 (Connection refused)
mount: trying 10.140.48.165 prog 100003 vers 3 prot tcp port 49064
mount: Unable to connect to 10.140.48.165:49064, errno 111 (Connection refused)
mount: mount to NFS server '10.140.48.165' failed: System Error: Connection refused.

me parece que o servidor só esta escutando coenoes via 127.0.0.1, porem nao achei onde cosnertar isso!
Desculpem o long post! Agradeço a ajuda!
