NFS client firewall config?

02-18-2010, 10:00 AM

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:

root@saturn:[~]$ mount master1.mydomain.co.za:/saturn /bckmount: mount to NFS server 'master1.mydomain.co.za' failed: RPC Error: Unable to send.

I have added ports 111 & 2049 in both the TCP & UDP ingres & exgress ranges, but that doesn't seem to help. portmap & nfs is running as well. But as I say, as soon as I disable the firewall, it mounts fine.*

Google search results reveal a lot of different ports, like 4000:4004, 83xxxx (something, I forgot) but it still doesn't help.*

root@saturn:[~]$ rpcinfo -p

Hi

You need 2 ports open 2049/udp 2049/tcp but you should read this little
howto

Hi,

NFS by default uses random high numbered ports. See "48996 nlockmgr" above.
You need to tie them down to allow them through your firewall

Create the following file /etc/sysconfig/nfs

#/etc/sysconfig/nfs
# Created 05.07.05 by Tony Molloy

# Number of NFS threads to run
RPCNFSDCOUNT=48

# ports for statd daemon
STATD_PORT=4000
STATD_OUTGOING_PORT=4004

# ports for lockd daemon
LOCKD_TCPPORT=4001
LOCKD_UDPPORT=4001

# ports for mountd daemon
#MOUNTD_NFS_V2=no
#MOUNTD_NFS_V3=no
MOUNTD_PORT=4002

# ports for rquota daemon
#RQUOTAD=no
RQUOTAD_PORT=4003

Then open ports 4000:4004 in you firewall as well as port 111 the portmapper
and port 2049 for NFS

Hope this helps,

Tony

Hi Tony,*
Where do I do this? On the NFS server, or the NSF client?*
4 other NFS clients have connected to this server*successfully, and I used the same settings (i.e. opened port 111 & 4096) on the client's firewall

Put the file on the NFS server and open the ports on the NFS server. Then
restart NFS services

# service nfs start
# service nfslock start

To make these permanent

# chkconfig --level 35 nfs on
# chkconfig --level 35 nfslock on

Check with rpcinfo that NFS is using the specified ports.

I would strongly recommend using NFS4 if at all possible.

See Chapter 18 for NFS in general and 18.8 for security issues

Hi,

NFS by default uses random high numbered ports. See "48996 *nlockmgr" above.

You need to tie them down to allow them through your firewall

Create the following file /etc/sysconfig/nfs

#/etc/sysconfig/nfs

# Created 05.07.05 by Tony Molloy

# Number of NFS threads to run

RPCNFSDCOUNT=48

# ports for statd daemon

STATD_PORT=4000

STATD_OUTGOING_PORT=4004

# ports for lockd daemon

LOCKD_TCPPORT=4001

LOCKD_UDPPORT=4001

# ports for mountd daemon

#MOUNTD_NFS_V2=no

#MOUNTD_NFS_V3=no

MOUNTD_PORT=4002

# ports for rquota daemon

#RQUOTAD=no

RQUOTAD_PORT=4003

Then open ports 4000:4004 in you firewall as well as port 111 the portmapper

and port 2049 for NFS

Hope this helps,

Tony

Hi,*
How do I install NFS4, exactly? The server runs CentOS 5.4 with all the latest kernel & software updates. From what I can gather on google, NFS is NFS, is NFS?
