Machine Requirements
You must install the DCE binaries on each machine on which they will run. Ensure that each machine meets the following requirements:
· Disk Space
The machine must meet the disk space requirements outlined in Location of Installed DCE Files.
· Required Ethernet Addresses
Each machine must have an Ethernet address (a 12-digit hexadecimal number registered with the IEEE), usually contained on the
Ethernet card. Some operating systems, like the AIX for example, provide routines to access the Ethernet address from the card. Others, like OSF/1 for example, do not. For these machines, store
the Ethernet address in a file named /etc/ieee_802_addr. The file should contain the only the 12-hexadecimal digits address in text form, for example, 08002BFFFFFF.
· Wide Area Network (WAN) Connections
If you will be configuring DCE over a WAN, set up the following ports for receiving packets on both ends of the WAN
connection:
- udp port 88 for Kerberos
- udp port 135 for the dced daemon
- tcp port 135 for the dced daemon
- All udp and tcp ports greater than 1024 for all DCE services and applications
