46 OES 2 SP3: Planning and Implementation Guide
3.9.20 VNC Install Fails to Set the IP Address in /etc/hosts
If you install through a VNC connection, the
/etc/hosts
file is configured with a loop back
address assigned to the hostname. This can cause problems with services.
Using a text editor, modify
/etc/hosts
so that the hostname is associated with its actual IP
address.
3.10 Consider Coexistence and Migration Issues
You probably have a network that is already providing services to network users. In many cases, the
services you are currently running will influence your approach to implementing OES 2. In some
cases, there are specific paths to follow so that the OES 2 integration process is as smooth as
possible.
Novell has invested considerable effort in identifying service coexistence and migration issues you
might face. We understand, however, that we can’t anticipate every combination of services that you
might have. Therefore, we intend to continue developing coexistence and migration information.
For information about coexistence of OES 2 servers with existing NetWare and Linux networks, see
Chapter 8, “Migrating and Consolidating Existing Servers and Data,” on page 73 .
