Introduction to Advanced Server for UNIX

Shared resources

2.2.1.1System name

Each UNIX system has a unique name in the network, which can be displayed using the command uname -nand set as the network node name using the SYSADM utility program.

In order to avoid problems, it is strongly recommended that the system names you ! assign are unique throughout the network. While the same system name may

appear several times in different DNS domains, even in the same network, Advanced Server for UNIX uses the system name internally for generating names which must always be unique.

2.2.1.2 Computername (server name)

Servers and clients must have a unique name in the network, known as the computername. The computername of a server is also called server name.

A proposed server name is derived from the first 15 characters of the system name when it is being installed first. The terms computername and server name are used synony- mously in relation to the server.

It can be changed to any name (with a maximum of fifteen characters) during installation. The server name is stored automatically in the lanman.ini file on the server. It is part of the network name and may only be changed after the installation using special utility programs. For further information please refer to the section entitled “Changing server attributes” in the chapter entitled “Administration guidelines”.

The server name consists of up to fifteen characters: letters from a to z, numbers from 0 to 9 and the special characters -.~!#$%^&()_{}.

In the previous Version 2.0, the server name for the LAN Manager/X server had the suffix .serve. Please note that both LAN Manager/X Version 2.2 and Advanced Server for UNIX up to version 4.0A10 propose the suffix .srv for a first installation instead.

Since Advanced Server for UNIX V4.0B, the default server name proposed during the first installation is built from the system name without an extension.

In order not to run into problems when upgrading to upcoming NT/AS/X- versions in the future, all tools requesting a server name during installation or reconfiguration offer the DNS-compatible host name (‘uname -n‘) as the default server name. The extension .srv can still be used, but is not recommended and no longer offered as a default. Installation/configuration scripts now inform the administrator about DNS-incompatible server names.
