NFS - Permission denied by server

[jyer]

Hello,
I've been configuring an NFS server on my local network. I'm pretty sure I set up the server and configured the export, hosts.allow and hosts.deny correctely (I followed the NFS HowTO)*. Nevertheless, as I want to mount a filesystem from the client (ubuntu), the server (debian) denies permission. I've checked that the user name has the same IUD number on the server and client side.

A quick google up led me to the following sentence:

I have encountered a problem using autofs to mount remote nfs shares. The problem was that the server's log reports successful authentication whereas the client told "permission denied by server". The workaround is to put "/etc/init.d/portmap restart" into "/etc/conf.d/local.start". That problem seems to be related to how portmap and nfs interact...

Being a newbye, this unfortunately didn't help me that much. Questions are the following:
1. How do I access the server's log reports
2. What does s/he mean by "put "/etc/init.d/portmap restart" into "/etc/conf.d/local.start""?
3. Do you think this problem could be linked to the fact that Ubuntu doesn't provide a "root" and that I have to sudo mount?

Thanks in advance,
jr

access the log reports at
/var/log/messages
Can you manually mount the nfs exports at the client?(try mounting on the server too,on itself)
Do you have any firewall that might obstruct your exports?

Hi,
Thanks for you reply.
According to the log:

Jul 17 19:22:29 latitude rpc.mountd: refused mount request from razor for /home/jyer/mp3 (/): no export entry

Trying to mount the file on the server, I get the following message:

I assume "mount 192.168.1.35:/home/jyer/mp3 /mnt/mp3" is the right way to do so?)

This though I specified in my hosts.allow file that 127.0.0.1 should be granted access. And the exports file contains:

/home/jyer/mp3 127.0.0.1(secure,ro,no_root_squash)

Any clue?

[nature]

seems that portmap isn't running,do a
rpcinfo -p
at server

the output would be something like: (from the web)

100000 2 tcp 111 portmapper
     100000 2 udp 111 portmapper
     100021 1 udp 32774 nlockmgr
     100021 3 udp 32774 nlockmgr
     100021 4 udp 32774 nlockmgr
     100021 1 tcp 34121 nlockmgr
     100021 3 tcp 34121 nlockmgr

     100011 2 udp 933 rquotad
     100011 1 tcp 936 rquotad
     100011 2 tcp 936 rquotad
     100003 2 udp 2049 nfs
     100003 3 udp 2049 nfs
     100003 2 tcp 2049 nfs
     100003 3 tcp 2049 nfs
     100005 1 udp 960 mountd
     100005 1 tcp 963 mountd
     100005 2 udp 960 mountd
     100005 2 tcp 963 mountd
     100005 3 udp 960 mountd
     100005 3 tcp 963 mountd

all these should be registered with portmap and running

Here's my preview, seems pretty similar to yours, no?

    100024    1   tcp    842  status

Does the following sentence mean anything to you?

The workaround is to put "/etc/init.d/portmap restart" into "/etc/conf.d/local.start".

Does the following sentence mean anything to you?

do you have any file /etc/conf.d/local.start(this is the file in gentoo?..)
that might be file that starts all the scripts in it at boot
so putting /etc/init.d/portmap starts portmap everytime at boot..
http://gentoo-wiki.com/TIP_List_of_Configuration_Files

edit:I notice you have a debian
so if you want to do the same, put it in
/etc/init.d/rc.local

[jyer]

Ok. I didn't realize it was Gentoo specific. That's a least a good reason for not understanding it

put it in /etc/init.d/rc.local

I still neither understand what I'm suppose to "put" or what you mean by "put" in the first place. I don't have any rc.local, so don't even know if it's a file or a directory!
Even so, do you have any clue about why my NFS doesn't work?

[nature]

let us troubleshoot,

1)do you have the line

portmap: ALL

in /etc/host.deny (but without allowing your clients in /etc/host.allow like)

 portmap: 192.168.0.1 , 192.168.0.2

ofcourse the ports are open to the clients(as seen from rpcinfo -p)

2)do a
ps aux | grep portmap
and make sure portmap is running(indeed rpcinfo -p shows that portmapper is running in your case)

2)I have an exports entry like this

/u/home  xxxxx(rw,sync,no_root_squash) which works fine

and a very good tutorial:http://www.faqs.org/docs/Linux-HOWTO/NFS-HOWTO.html
to troubleshoot

I still neither understand what I'm suppose to "put" or what you mean by "put" in the first place. I don't have any rc.local, so don't even know if it's a file or a directory

and you need not do that right now because your portmap is up and running

Jul 17 19:22:29 latitude rpc.mountd: refused mount request from razor for /home/jyer/mp3 (/): no export entry

the log says that you do not have an export entry,
Is your /etc/exports file error free?

and finally,be sure to restart nfs after you have made any changes
/etc/init.d/nfs restart
{or /etc/init.d/nfs-common restart
and /etc/init.d/nfs-kernel-server restart}

Hi,
Thanks for your answer. I reread the tutorial. It turns out I didn't install the nfs-utils package on the server. Hence I don't have the Daemons running on my server.
The problem is that I can't install the nfs-utils package. According to apt-get, the packages simply doesn't exist ("couldn't find package nfs-utils").
I tried on another computer running ubuntu and couldn't find the package either. A research on http://packages.debian.org informed me that the package didn't seem to exist.
Does anyone know where I can find it? If you try an apt-get install, do you get it? If so, what is your sources.list?
+
According to the Tutorial, I should "include the doemons in the startup scripts". How do I do that (providing I manage to install them
Thanks,
jr
