Hi,

I would like to ask for some advice on how to solve this. I need to mount a directory from a remote machine to another machine in linux environment. The NFS server is set up and running. However, I couldn't mount the directory from the client machine. Both machines' /etc/hosts has each others addresses. I am also able to ping the server machine. But when i try to mount the directory, it gives this error:

[root@sit36 /root]# mount 172.20.134.37:/usr/local/blast /mnt/blast
mount: RPC: Unable to receive; errno = Connection refused

I really don't know what did i miss out. Can you give me some advice on this.

And when i try to FTP the NFS server machine, the connection is also refused. Could this be the problem? Though i've set the NFS server machine to a FTP server also.

Thanks alot for your attention. I really need help asap. Thanks

You need to be running the rpc.portmap program, as well as nfsd,
and mountd on the server. You also need to have the disk you
want to export in the /etc/exports file (before you start mountd or
nfsd) on the server.

man exports
man nfsd
man mountd
man portmap

The NFS connection refused problem may be related, but only
indirectly. You'll need to check that there either
1) there is nothing in the /etc/hosts.deny file that excludes your
client, or, if there is an exclusion in /etc/hosts.deny,
2) there is something in /etc/hosts.allow file that includes your
client.
If this is all fine, you need to be sure your ftpd program is up,
by either editing /etc/(x)inetd and uncommenting the ftp line,
or by making sure ftpd is started before you try to connect.

man ftpd
man inted
man xinted
man hosts.allow
man hosts.deny
