Setting up NIM for different networks

Hi,

I am struggling setting up a NIM master to serve hosts on a network that is not directly accessible through the "master"-s default interface. I now that I need to set up network definitions and maybe NIM routes, but got confused.

The master has 2 interfaces:
* en0 holding the address which is belonging to its hostname, therefore the AIX default gateway is using that interface (let's call this Network-master1)
* en1 holding IP address from another network. Hosts from this network are enabled to communicate with hosts from my target network, but that communication needs a static route to be set up in the OS - as the default gw routes in a wrong direction. (Let's cal this Network-master2)

And there is another network, holding the to-be-clients - Let's call this Network-client

Every object is served from the master. If I understand correctly, I only need NIM routes is some objects are served from different nodes, thus I would not need this. Is that right?

I tried to set up a second install interface for the master, but as it is part of Network-master2 and not Network-client, I was unable to make NIM to set bootp server address to its second interface IP. It always put "sa=IP.ON.FIRST.INTERFACE" and therefore the client is unable to get its boot package.

Now I am stuck. Can you please help me?

Best regards,

Networks alternative to Internet

I've read about BITNET, CompuServe... CompuServe was probably not a network but an online service. Are (were) there any other networks alternative to Internet? Does anyone have experience with them?

Multiple networks on same server

If I have 2 interfaces in a server on the same subnet/network does Solaris automatically choose to route packets destined for this network out the first interface. I.e if ce0 and ce1 were on same network ce0 would be chosen as it's first interface?

routes

routes(4)						     Kernel Interfaces Manual							 routes(4)

NAME

       routes - Specifies Internet routing information to the routing tables

SYNOPSIS

       /etc/routes

DESCRIPTION

       Static  routes  can  be defined in the /etc/routes file.  The /etc/routes file identifies static routes that are automatically added to the
       network routing tables with the /usr/sbin/route add command.  The /sbin/init.d/route script contains the /usr/sbin/route add  command  that
       is executed for each entry in the /etc/routes file when the network is restarted on the system or the system is rebooted.

       The general format of an entry in the /etc/routes file is: Dest Name1 Name2

       The  following is a brief description of each element in an /etc/routes file entry: A keyword that indicates whether the route is to a net-
       work or to a host. The two possible keywords are -net and -host.  The name or address of the destination network or  host.   Name1  can	be
       either  a  symbolic  name (as used in the /etc/hosts or /etc/networks file) or an Internet address specified in dotted-decimal format.  The
       name or address of the gateway host to which messages should be forwarded.  Name2 can be either a symbolic name (as used in the	/etc/hosts
       file) or an Internet address specified in dotted-decimal format.

       The  routes file is a Context-Dependent Symbolic Link (CDSL) and must be maintained as such.  See the System Administration manual for more
       information.

EXAMPLES

       To specify a route to a network through a gateway host with an entry in the /etc/routes file, enter:

       -net net2 host4

	      This example specifies a route to a network, net2, through the gateway host4.  To specify a route to a host through a  gateway  host
	      with an entry in the /etc/routes file, enter:

	      -host host2 host4

	      This  example  specifies	a route to a host, host2, through the gateway host4.  To specify a route to a default gateway host with an
	      entry in the /etc/routes file, enter:

	      default 130.9.0.5

	      This example specifies a route to a default gateway with an Internet address of 130.9.0.5.

FILES

       Contains the /usr/sbin/routed add command.
