Setting up NFS between two Linux boxes

[JockVSJock]

Here is what I have going:

Two RH machines, 7.1 (hostname hoth) and 8 (hostname phoenix), and one is a gateway/router/dhcp server/firewall and the other is just a pc.

I want to setup NFS between the two so I can move files among them. One, is this bad from a security standpoint? Since Hoth is a gateway/router/dchp/firewall.

Two. To set this up. I would setup /etc/exports like

/home/foo hoth

Can I put in the hostname, since I am running DHCP?

thanks

its security would depend, I think, on your firewall setup. Are you using chains or tables? U need to set it up to disallow any nfs connections on anything but your systems. Also, why dhcp? If it is just those two boxes, it is much easier to just go with a static ip. /etc/exports is the file used to setup the exported filesysytem, but to be on the safefguide I would go to www.tldp.org and get the how-to. Better safe than sorry.

I will use iptables and I will block nfs then. What about ssh cause I do have that setup as well? I don't want to block ssh at my firewall cause I want to be able to ssh into any of my machines on my network, I will have 3.

BTW, is DHCP not the way to go then? I really don't want to worry/manage this.

thanks

If you only have 3 machines then i would just setup a static ip. That would make your config alot easier.

SSH is fine to allow through the firewall. That is one of the main purposes behind it. Its a "Secured" Shell, so it uses an encrypted password where apps like telnet do not, by using an rsa encryption protocol.
