file contains the hostname of the IRIS 3010. The information that goes into the
host tables is described in the documentation that accompanies the
communications software.
A sample hostname file,
sys_id , is included in the host distribution. To give
the IRIS 3010 a hostname, edit this file to contain the desired name, and then
enter the command:
iftp w sys_id /etc/sys_id
Hostnames must not be more than eight characters.
Next, create the two host table files on the host. Then transfer them to the
IRIS 3010 terminal disk. If, for example, the two files on the host are named
hosts and hosts.equiv , enter these commands:
iftp w hosts /etc/hosts
iftp w hosts.equiv /etc/hosts.equiv
Until these files exist on the IRIS 3010, the terminal emulator always prompts
for the Internet addresses of the IRIS and the host. Once the terminal
emulator knows the local address, it prompts only for the host address.
The terminal emulator can be configured to initiate a connection with a single
host automatically each time it is started up. This procedure is documented in
Section 5.2.1.
If the IRIS 3010 disk contains an invalid
/etc/hosts file, it will probably not be
able to communicate with the host. To recover from this situation, use one of
these strategies:
• Edit /etc/hosts locally on the IRIS 3010.
• Transfer a valid copy from the host over the serial communications line.
• Use the boot failure recovery procedure described in Section 5.2.5 to start
over.
5.3.5 Miscellaneous Unix Configuration
Time Zone
Several U
nix
utilities need to know the time zone in order to display the time
correctly. The time zone entry is contained in the file /etc/TZ . The file has
three fields:
1. A three-character abbreviation for the time zone.
