## 9. Network parameters

We will make a plip point-to-point network with this IP configuration:

- target: 192.168.0.1 netmask 255.255.255.255
- source: 192.168.0.2 netmask 255.255.255.255

You should not already have those names in your name space:

         $ ping source
         ping: unknown host source

         $ ping target
         ping: unknown host target

You should not already have those IP addresses in your network space:

         $ ping  192.168.0.1
         PING 192.168.0.1 (192.168.0.1): 56 data bytes
         ping: sendto: Network is unreachable
         ping: wrote 192.168.0.1 64 chars, ret=-1

         --- 192.168.0.1 ping statistics ---
         1 packets transmitted, 0 packets received, 100% packet loss

         $ ping 192.168.0.2
         PING 192.168.0.2 (192.168.0.2): 56 data bytes
         ping: sendto: Network is unreachable
         ping: wrote 192.168.0.2 64 chars, ret=-1

         --- 192.168.0.2 ping statistics ---
         1 packets transmitted, 0 packets received, 100% packet loss

If those commands don't give you errors, change the names or the addresses.

You can choose other addresses, names or netmask (netmask must be the same on both sides). In the rest of this document, I'll suppose you choose these addresses and these names.

Add a line in `/etc/exports`

         #### file /etc/exports ####
         ...
         /cdrom          source(ro) target(ro)
         #### EOF ####

Because the portmapper tries to resolve IP addresses, add the IP addresses and names in `/etc/hosts`

         #### file /etc/hosts ####
         ...
         192.168.0.1     target
         192.168.0.2     source
         #### EOF ####

Verify you have the item `files` for the `hosts` search list in the file `/etc/nsswitch.conf`

         #### file /etc/nsswitch.conf ####
         ...
         hosts:      files nis dns
         ...
         #### EOF ####
