NFS on Ubuntu 12.04 (Perfect Server) not working

[profm2]

Hi all,

I'm trying to get NFS setup on my Ubuntu 12.04 that was initially installed using the perfect server guide.

Running netstat -antp yields:

tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      948/mysqld      
tcp        0      0 0.0.0.0:111             0.0.0.0:*               LISTEN      565/rpcbind     
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      2031/nginx
tcp        0      0 0.0.0.0:732             0.0.0.0:*               LISTEN      2252/rpc.rquotad
tcp        0      0 0.0.0.0:55901           0.0.0.0:*               LISTEN      17227/rpc.mountd
tcp        0      0 0.0.0.0:2049            0.0.0.0:*               LISTEN      -               
tcp        0      0 0.0.0.0:43585           0.0.0.0:*               LISTEN      816/rpc.statd   
tcp        0      0 0.0.0.0:34662           0.0.0.0:*               LISTEN      17227/rpc.mountd

It would appear that 2049 is not bound to any program ... and rpcbind is running on port 111.

From my Linux laptop, when I run nmap -O server ... I get:

Nmap scan report for server (192.168.xxx.xxx)
Host is up (0.0011s latency).
Not shown: 985 filtered ports
PORT      STATE  SERVICE
20/tcp    closed ftp-data
21/tcp    open   ftp
22/tcp    open   ssh
25/tcp    open   smtp
53/tcp    open   domain
80/tcp    open   http
110/tcp   open   pop3
143/tcp   open   imap
443/tcp   open   https
993/tcp   open   imaps
995/tcp   open   pop3s
3306/tcp  open   mysql
8080/tcp  open   http-proxy
8081/tcp  open   blackice-icecap
10000/tcp closed snet-sensor-mgmt
...

So, from my laptop, I don't see port 2049 or 111 ... the two that I should see.

I also have a NAS that I'm running NFS on and when I run nmap -O data ... I get:

Nmap scan report for data (192.168.xxx.xxx)
Host is up (0.0025s latency).
Not shown: 989 closed ports
PORT     STATE SERVICE
22/tcp   open  ssh
80/tcp   open  http
111/tcp  open  rpcbind
139/tcp  open  netbios-ssn
443/tcp  open  https
445/tcp  open  microsoft-ds
515/tcp  open  printer
1025/tcp open  NFS-or-IIS
1026/tcp open  LSA-or-nterm
1027/tcp open  IIS
2049/tcp open  nfs

So, based on that info, I'm sure my server isn't opening the ports.

I've followed the HowTo from the Ubuntu site SettingUpNFSHowTo to the letter, multiple times, but still I cannot get NFS to work correctly. One thing I did notice, is that rpcbind is running in place of portmap.

Note, selecting 'rpcbind' instead of 'portmap'
rpcbind is already the newest version.

Any thoughts?

Did you check your logs for errors?

What happens after you run

exportfs -a

?

Hi Falko,

I've looked in the logs, but haven't found anything useful.

I did notice "gaps" in rpcinfo -p

One thing I forgot to test, was turning off my NFS client to a network attached storage drive that I have around. I would assume that I should be able to run the client and server at the same time, but maybe not.
