Don't enter or alter any gateways or other routing information.

No routing whatsoever is needed to talk over a point-to-point link, or over the local subnet -- routing and gateways only get involved for things beyond the local network.

All that's needed for two computers connected loopback to ping each other, for instance, is:

Code:
# on host 1
ifconfig eth0 up
ifconfig eth0 192.168.0.100 netmask 255.255.255.0


# on host 2
ifconfig eth0 up
ifconfig eth0 192.168.0.101 netmask 255.255.255.0

The OS will automatically pick the right interface for local traffic based on IP address and subnet mask.

tgt-setup-lun(8)					      System Manager's Manual						  tgt-setup-lun(8)

NAME

       tgt-setup-lun - creates a target, adds a device to the target and defines initiators that can connect to the target

SYNOPSIS

       tgt-setup-lun -d device -n target_name [initiator_IP1 initiator_IP2 ...] [-h]

DESCRIPTION

       Starts tgtd if necessary and creates a target according to the supplied target_name. The format of the target name is as follows:
       iqn.2001-04.com.<hostname>-<target_name> The target name must be unique.

       The  script then adds the requested device to the target. If specific IP addresses are defined, it adds them to the list of allowed initia-
       tors for that target. If no IP addresses is defined, it defines that the target accepts any initiator.

EXAMPLES

       Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81:
       tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81

       Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81 and 192.168.10.82:
       tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81 192.168.10.82

       Create a target that uses /dev/sdb1 and allows connections from any initiator:
       tgt-setup-lun -d /dev/sdb1 -n my_target

       Display help:
       tgt-setup-lun -h
