Linuxhelp _ Technical Support _ adding computers to network

Posted by: nvelissa Oct 6 2008, 11:16 PM

i am a student at rosalind franklin university for medicine and science. i am a first year with not very much linux experience and we are adding computers to our neuroimaging lab. we are haveing problem adding two new computers to a network file sharing(nfs) on a linux network. one is on red hat 9, the other is an imac running os10.3.9

the other computers are running red hat or fedora core and are working properly. we have properly configured host table and fstab file on both client and host. we know the network is working properly because ssh allows access to the host. we however, have no access to any of the data through nfs.

any advice or help for me?

Post the hosts /etc/exports directory.
Make sure any firewall (iptables) has been disabled on the clients.
Try manually mounting the nfs share.
What do you mean by host table?

Here is my exports file:
/home pigpen(rw,sync,nohide) 192.168.43.44/255.255.255.0(rw,sync,nohide) lucy(rw,sync,nohide)
homer(rw,sync,nohide) 192.168.43.46/255.255.255.0(rw,sync,nohide)
/share/brains2 pigpen(rw,sync,nohide) 192.168.43.44/255.255.255.0(rw,sync,nohide) lucy(rw,sync,nohide)
homer(rw,sync,nohide) 192.168.43.46/255.255.255.0(rw,sync,nohide)
/share/afni pigpen(rw,sync,nohide) 192.168.43.44/255.255.255.0(rw,sync,nohide) lucy(rw,sync,nohide)
homer(rw,sync,nohide) 192.168.43.46/255.255.255.0(rw,sync,nohide)
/usr/local/brains2 pigpen(rw,sync,nohide) 192.168.43.44/255.255.255.0(rw,sync,nohide) lucy(rw,sync,nohide)
homer(rw,sync,nohide) 192.168.43.46/255.255.255.0(rw,sync,nohide)
/usr/local/matlab74_sv pigpen(rw,sync,nohide) 192.168.43.44/255.255.255.0(rw,sync,nohide) lucy(rw,sync,nohide)
homer(rw,sync,nohide) 192.168.43.46/255.255.255.0(rw,sync,nohide)
/usr/local/mricro pigpen(rw,sync,nohide) 192.168.43.44/255.255.255.0(rw,sync,nohide) lucy(rw,sync,nohide)
homer(rw,sync,nohide) 192.168.43.46/255.255.255.0(rw,sync,nohide)

I can't find the iptables on the mac or linux. Any suggestions to where this file is? I know it can vary. How do I search for it?
How do I manually mount the nfs share?
Sorry, by hosts table, I just mean "hosts" (/etc/hosts).

You are exporting to lucy and pigpen and

192.168.43.44/255.255.255.0(rw,sync,nohide)

However, to add a share for the entire network you would use 192.168.43.0/255.255.255.0(rw,sync,nohide) or 192.168.43.0/24(rw,sync,nohide)

Is this what you want to accomplish? Be sure to restart nfs for changes to take affect.

On the linux PC (as root) look at the output of the command
iptables -L
