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?

cmpt_get_ifcid(3)					     Library Functions Manual						 cmpt_get_ifcid(3)

NAME

       cmpt_get_ifcid(), cmpt_get_addrcid() - get the compartment IDs associated with a network interfaces

SYNOPSIS


   Parameters
	      ifname	Pointer to network interface name string.

	      family	Address family of the ipaddress specified.  Currently, the AF_INET and AF_INET6 address families are supported.

	      addr	Points to a buffer holding an IPv4 address if the family argument is AF_INET or an IPv6 address if the family is AF_INET6.
			The address should be in numeric format in the network byte order.  Numeric format is the binary value that  goes  into  a
			socket address structure.

			The  binary value is the hex representation of the IPv4/IPv6 address.  This binary value resides in the structure for IPv4
			address and in the structure for IPv6 address.	(See inet(3N) for more details.)

	      mask	Network mask in the CIDR representation.

DESCRIPTION

       The function returns the compartment ID associated with a network interface.

       The function returns the compartment ID of the tuple as set by a previous invocation of the command.

RETURN VALUE

       The functions and return the following values:

	      Successful completion.
		      n is the compartment of the interface or the tuple.

	      Function failed.
		      may be set to indicate the error.

ERRORS

       If any of the following conditions occur, and fails and sets

	      Compartmentalization feature is not supported.

	      The process does not have the appropriate privilege.
			     See privileges(5).

	      Specified interface or the address tuple has no compartment mapping.

	      Specified mask or family is invalid.

DEPENDENCIES

       These functions are a part of the library.
