[cobalt-users] [Raq2/Qube2] Sleeping nfsoid loaded in Kernels?

["James Hoaggs" <james_hoaggs@xxxxxxxxxx>]

Hi list,
Our machines for some reason run client processes that are stuck in the
kernel for a while as "nfsoid".  NFS is a connectionless and stateless
protocol where NFS servers run on unpredictable port numbers via UDP
or TCP.  Is NFS still sleeping somewhere within the NFS code via the
kernel or modules based on our results below?
[root@www /]# chkconfig --list :
nsf 0:off 1:off 2:off 3:on 4:off 5:on 6:off
...
[root@www /]# /sbin/chkconfig --del nfs
nsf 0:off 1:off 2:off 3:off 4:off 5:off 6:off
...
Then we still have client nfs by doing this :
[root@www /]# ps aux | grep nfs :
root            6  0.0  0.0  0   0  ?  SW Nov 10 0:00 (nfsiod)
root            7  0.0  0.0  0   0  ?  SW Nov 10 0:00 (nfsiod)
root            8  0.0  0.0  0   0  ?  SW Nov 10 0:00 (nfsiod)
root            9  0.0  0.0  0   0  ?  SW Nov 10 0:00 (nfsiod)
In /etc/inetd.conf there are no nfs entries; the only
place on the box for nfsd that we found is :
/usr/sbin/rpc.nfsd

So we did:
[root@www /]# /usr/sbin/rpc.nfsd --version   or
[root@www /]# /usr/sbin/showmount --version
we received:
Universal NFS Server 2.2beta37

When we do a /etc/rc.d/init.d/nfs status we get:
rpc.mountd is stopped
rpc.nfsd is stopped
By issuing the command it looks like it just stopped,
just like when you stop ssh and such.
NFS is very insecure - file systems can be mounted and remounted even
if the computer is re-booted, shutdown, or even disk copied to an other
hard drive, the file systems can still be accessed at a later time. Hence
we ask how to remove nfsoid from being generated at startup.

Chaio,
