Problem on config NFS as server

[Stephen Liu]

Hi folks,

Ubuntu-6.06.1-server-amd64
Broadband connection via ADSL modem --> telephone line
Dynamic IP addr.


I'm now configuring the server for test only and stuck on NFS
configuration.

$ cat /etc/hosts
127.0.0.1	localhost	ubuntu

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
* end *

$ sudo /etc/init.d/nfs-kernel-server restart
Stopping rpc mounted ... [ok] 
Stopping rpc rfsd ... [ok] 
Unexporting directories for NFS kernel daemon ... [ok]
Exporting directories of NFS kernel ademon ... [ok] 
Starting rpc rfsd .... [fail]
* end *

$ cat /var/log/syslog | grep nfs
.....

* end *

$ cat /etc/network/interfaces
auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0
auth eth0
iface eth0 inet dhcp

auto dsl-provider
iface dsl-provider inet ppp
provider dsl-provider

# added by pppoeconf
auto eth0
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
* end *

Each time after booting PC, have to re-run "sudo pppoeconf" to make
broadband connection.  "sudo pon dsl-provider" does not work even no
complaint displayed.

Please help.  TIA

B.R.
