Summary
========================================================================

These notes provide guidelines to help you configure TOP to work
correctly in TCP/IP environments where there are multiple IP addresses
associated with the Himalaya node.

TOP must determine the IP address of Himalaya nodes to run FTP or
terminal emulation sessions on them. If there are multiple Ethernet
subnets, then TOP may use an inappropriate IP address. This means that
file transfers and terminal emulation will not function.

These guidelines enable you to specify the specific IP address that you
want to use for IP access to a Himalaya node.

Details
========================================================================

TOP uses the FTP protocol for performing file transfers and the Telnet
protocol for terminal emulation. Both protocols require an IP connection
to work correctly. For TOP to establish an IP connection to a Himalaya
node, it must know the IP address of the node.

When TOP establishes an IP connection to a node, it finds the IP address
of the node by examining the TCP/IP subnets on the node where the MIP is
running. When a subnet of type ETHERNET is found, the IP address
associated with that subnet is used as the IP address of the machine for
IP traffic.

Some nodes may be configured with more than one subnet of type ETHERNET.
In this case, TOP may use the wrong IP address for the host. For file
transfers and terminal emulation to function correctly, you must
explicitly override the incorrect IP address with the correct IP
address.

To force TOP to use a specific IP address for file transfers and
terminal emulation for a certain node:

1. On the Session menu, point to Options, and then click a node name.

2. Click in Host IP Address, and then specify a numeric IP address.

3. Click OK.
