Hello every one.

I trying to add NFS Mount on the Teradata Server.

I am logged in as root in the Linux and am trying to mount it with the below command

"mount -t nfs NFSSERVERNAME:/Disk /desitnation_Folder"

when I use this command I get the below error message, what should be the next step I can go with.

"mount server reported tcp not available, falling back to udp"

Re: NFS Mount : mount server reported tcp not available, falling back to udp : Error

If your nfs client has this:

# mount -t nfs NFSSERVERNAME:/Disk /desitnation_Folder

mount server reported tcp not available, falling back to udp

mount: RPC: Program not registered

and this:

# rpcinfo -p nfsserver-ip-address

No remote programs registered.

you may have tcpwrappers in the nfs server, so, in the nfs server edit /etc/hosts.allow and add:

portmap : ip : ALLOW

portmap : ALL : DENY

nfs-server : ip : ALLOW

nfs-server: ALL : DENY

do not restart anything, just mount your filesystem in the client
