FC3: NFS Server and Startup Scripts

General_Tso · 03-14-2005, 04:54 PM

Hello, folks.

I have been following this NFS Server How-To, and I have run into problem. I am not sure how to set up the startup scripts such that all the correct daemons are running as shown here:

Quote:

3.3.3. The Daemons

NFS serving is taken care of by five daemons: rpc.nfsd, which does most of the work; rpc.lockd and rpc.statd, which handle file locking; rpc.mountd, which handles the initial mount requests, and rpc.rquotad, which handles user file quotas on exported volumes. Starting with 2.2.18, lockd is called by nfsd upon demand, so you do not need to worry about starting it yourself. statd will need to be started separately. Most recent Linux distributions will have startup scripts for these daemons.

The daemons are all part of the nfs-utils package, and may be either in the /sbin directory or the /usr/sbin directory.

If your distribution does not include them in the startup scripts, then then you should add them, configured to start in the following order:

rpc.portmap
rpc.mountd, rpc.nfsd
rpc.statd, rpc.lockd (if necessary), and rpc.rquotad

Do anyone have some suggests or a startup script FAQ that they an point me to?

chkconfig portmap on
chkconfig nfs on

service portmap restart
service nfs restart

The top two switch on the deamons in runlevel 3 and 5.
The next two restart(start) the deamons.
Is that what you mean?

Thank you for your response. I have those running via those same commands. My trouble is getting the others started as are listed here:

rpc.portmap
rpc.mountd, rpc.nfsd
rpc.statd, rpc.lockd (if necessary), and rpc.rquotad

When I run the same commands with the above scripts, I receive an error to the effect of service not found. I do have the scripts: some are located in /sbin and others in /usr/sbin. Will I have to do a sym link from their current location to /etc/init.d (or wherever the scripts reside, I'm not at my linux machine) or can I use the chkconfig and service commands such that "chkconfig /sbin/rpc.portmap on."

Also, how does one order services? Just edit the conf file? This all is pretty new to me, so I don't want to tinker too much.

To see if there are running, which they should be, type
rpcinfo -p localhost

General_Tso · 03-16-2005, 01:16 PM

Seems like its all running, but I keep getting the following error: "NFS Portmap: RPC: Port mapper failure - RPC: Timed out." The NFS Server is FC3, and the NFS client is Mac OS 10.3.8.

Edited to Add: I had one of the two NFS ports closed, so after opening them I got the following error: "mount_nfs: bad MNT RPC: RPC: Timed out."

To see what you have exported type

showmount -e localhost

You should see the lists of exports.

Now try showmount -e <ip address>

You should get the same as before if nfs is setup properly.

If the above is ok try to mount the nfs export.

mount -t nfs <your export> <mount point>

General_Tso · 03-17-2005, 12:28 PM

Hmmm. "showmount -e localhost" does not show any anything in the export list. What am I doing wrong?

Thanks!

james.farrow · 03-17-2005, 01:01 PM

NFS
1) Edit the etc/exports file( here's mine)
/var/ftp/pub 192.168.1.0/24 192.168.2.0/24(ro,sync)
/mnt/music 192.168.1.0/24 192.168.2.0/24(ro,sync,no_root_squash)
/home 192.168.1.0/24 192.168.2.0/24(rw,sync)

2) save and quit
then run the command eportfs -rav
You should get a list of your exports.
3) now restart the service as stated above in an earlier post.

If that fails have you lokked in hosts.allow and hosts.deny?
Or try flushing your firewall iptables -F

General_Tso · 03-17-2005, 06:34 PM

Here's my /etc/exports:

Quote:

/home 192.168.1.1/255.255.255.0(rw,sync)
/var/ftp/pub 192.168.1.1/255.255.255.0(rw,sync)

Here's my /etc/hosts.allow:

Quote:

ssh: 192.168.1.1/255.255.255.0
vsftpd: 192.168.1.1/255.255.255.0
portmap: 192.168.1.1/255.255.255.0
lockd: 192.168.1.1/255.255.255.0
rquotad: 192.168.1.1/255.255.255.0
mountd: 192.168.1./255.255.255.0
statd: 192.168.1.1/255.255.255.0

Here's my /etc/hosts.deny:

Quote:

ssh:ALL
vsftpd:ALL
portmap:ALL
lockd:ALL
rquotad:ALL
mountd:ALL
statd:ALL

Well, something I did made the "showmount -e localhost" output appear.

Quote:

Export list for localhost:
/home 192.168.1.1/255.255.255.0
/var/ftp/pub 192.168.1.1/255.255.255.0

Here's what happen when I execute the command: sudo mount -t nfs 192.168.1.3:/home /Volumes

Quote:

NFS Portmap: RPC: Program not registered

Interestingly, when I execute "showmount -e 192.168.1.3" from my Powerbook, I get the following output:

Quote:

RPC: Program not registered: Can't do Exports rpc

Thanks for all the input so far!

james.farrow · 03-18-2005, 05:15 AM

Try adding the line

nfs: 192.168.1.1/255.255.255.0

to hosts.allow ,and change hosts.deny to only

ALL: ALL

Then restart the services and see what happens.

james.farrow · 03-18-2005, 05:21 AM

Another thought, change all the etc hosts.allow to

<service>: 192.168.1. 127. EXCEPT <any exceptions here i.e 192.168.2. etc>

and hosts.deny to as I said

ALL: ALL

Try that

General_Tso · 03-18-2005, 01:27 PM

Still getting "NFS Portmap: RPC: Program not registered."

james.farrow · 03-18-2005, 04:17 PM

I sugesst you comment out all the lines in hosts.allow and hosts.deny.
Then iptables -F followed by service iptables stop

Make sure that you can rpcinfo -p <nfs server> from another host on the network.
If thats ok try showmount - e <server name> from another host.
Then try the mount command from above.

General_Tso · 03-20-2005, 12:08 AM

Okay, I had a bit of breakthrough. With "ALL:ALL" commented in hosts.deny and everything as I listed before in hosts:allow, my NFS client worked! (To those of you trying to use your OS X machine as a host, you will have to add the "insecure" option to the directory you wish to share in your exports file as per this site.) On my NFS client, an app called nfs_mount seems to depend upon three ports: 672, 675, and 685. I'm not sure if this unique to OS X or common to all NFS clients, but I kept seeing it bounce off my firewall during my attempts to connect to the server.

Enter the "but." When I can connect to my /home directory, I do not have permission to access two of the three user directories. I'm worried my permissions are screwed up somehow--the inconsistency is what bugs me. Any thoughts?

Thanks for all the input, great info!
