firewalled NFS
Hi,
I'm trying to setup a firewalled NFS server. I've configured my server
(CentOS 5) using the following parameters
/etc/sysconfig/nfs

RQUOTAD_PORT=875
LOCKD_TCPPORT=32803

NFS problem
I'm trying to NFS-mount a CentOS directory on my Fedora laptop,
but I find I can only do this is I turn off the firewall
on the CentOS server.
If instead I go to system-config-securitylevel-tui on the server,
and allow NFS4, this does not do the trick.
Nor does allowing port 2049.
What do I need to allow?
[I should say that the CentOS server is remote,
and difficult to access directly;

NFS and Firewall
Hi Folks,
I'm using VMWare on a Linux Host (CentOS) with a Linux-Guest Sidux).
And I'd like to use NFS.
Furthermore I'd like to use the Firewall in CentOS with this little GUI.
If I activate this firewall then my Guest says "no route to host" on mounting
nfs.
Firewall disabled -> no problem occurs.
Is there a solution to use firewall _and_ nfs ?
Please, no iptables

NFS, acls, proto, and "kernel: svc: unknown version"
Hi all,
1) My NFS3 clients don't display or obey existing non-POSIX ACLs on
files of NFS3-mounted exports.
2) setfacl on the client throws error and fails :
# setfacl -m u:stowler:rw testfile.text
setfacl: testfile.text: Operation not supported
3) at time of client mount the server's /var/log/messages shows
"kernel: svc: unknown version (3)".
Any thoughts greatly

firewall issue
Hello everyone,
I am setting up a new system for use as a testing/demo/trial-and-error
system. I have installed CentOS 4.4 on it. There is not an
X-environment, so I will need to fix this from the command line (via ssh
access).
I am trying to do an nfs export from this box to another on my internal
home network. I have figured out that it is a firewall issue on the
CentOS box (I turn off the

Why portmap is needed for NFSv4 in CentOS6
Hi all,
I have setup a CentOS6.3 x86_64 host to act as a nfs server.
According to RHEL6 docs, portmap is not needed when you use NFSv4, but
in my host I need to start rpcbind service to make NFSv4 works.
My /etc/sysconfig/nfs
#
# Define which protocol versions mountd
# will advertise. The values are "no" or "yes"
# with yes being the default

NFS client firewall config?
Hi all,
Which ports do I need to have open on an NFS client's firewall to allow it
to connect to a remote NFS servers?
When I disable iptables (using ConfigServerFirewall), it connects fine, but
as soon as I enable it, NFS gives me this error:

Unable to mount Centos 5.6 Server via nfs4 - Operation Not Permitted - MADNESS!
After getting a reasonably configured NFS4 setup working on my Scientific Linux server, I spent a majority of my evening trying to do the same with my Centos 5 box, with fruitless results. Most attempts to mount that server returns the following message:

NFSv4 on CentOS 5.5
Hi,
What is the magic juju that I have to put in /etc/sysconfig/autofs to
get autofs to default to using NFSv4, rather than NFSv3, for mounting
file systems?
I don't want to place these flags into the automount maps themselves
because we have a varied network with Sun, CentOS, RedHat and
Macintosh systems, and the flags that have to get added to automount
maps (which we distribute centrally

statd random port - sysconfig/nfs not taking effect
I have changed /etc/sysconfig/nfs to specify port numbers for NFS
daemons. Somehow statd is still starting up at random port number.
Other damons are starting at properly at specified port numbers Any
clues on what might be wrong? Any other location/setting that takes
precedence over sysconfig/nfs ? It's CentOS 5.5 64bit with nfs-utils
1.0.9-44.el5.

nlockdmgr listen on privileged port
hey list!
I am attempting to shore up some centos machines (ranging from centos
5 to centos 5.4) for pci compliance by changing the port that
nlockdmgr listens on to function under a privileged port.
So what I did was try to hardcode the port by editing /etc/sysconfig/nfs
# TCP port rpc.lockd should listen on.
LOCKD_TCPPORT=1011
# UDP port rpc.lockd should listen on.
LOCKD_UDPPORT=1011

mountd and statd at specific ports - nfs firewall
Hi,
I am configuring firewall for NFS.
I see that statd and mountd start at random port. Is there any way to
force it to start at specific port each time. The '-p ' option would
work, but how do I configure it to start at specific port number each
time. I mean where do statd and mountd look for default configuration
options? Any clues?

Netinstall & NFS using local server.
Dear CentOS community,
I have install centos via CD, DVD and Directly off the net via http and FTP. Now I want to do a NFS install from a local server and a client. Both, client and server are in the same vlan 10.14.10.0/255.255.255.0.
The server has a static 10.14.10.15 address and the client gets its own address via DHCP. I download the DVD image from one of the mirrors and placed it under

Help with NFSV4 server

an odd issue. Mounting the /nfs4exports/share appears to be successful
and the information displayed about partition size and free space seem
correct but if I try to do anything inside the mounted directory the
client will just hang. Does anyone have any idea what I am missing?? I
