...
In the new format, you still map the nodes to the LSF hosts, so the number of lines
remains the same, but the format is simplified because you only have to specify ranges
for the nodes, not each node individually as an alias:
...
177.16.1.1 atlasD0 atlas[0-31]
177.16.1.2 atlasD1 atlas[32-63]
...
Host name services
Digital UNIX
On Digital Unix systems, the /etc/svc.conf file controls which host name service
is used.
Solaris
On Solaris systems, the /etc/nsswitch.conf file controls the name service.
Other UNIX
platforms
On other UNIX platforms, the following rules apply:
◆ If your host has an /etc/resolv.conf file, your host is using DNS for name
lookups
◆ If the command ypcat hosts prints out a list of host addresses and names, your
system is looking up names in NIS
◆ Otherwise, host names are looked up in the /etc/hosts file
For more information
The man pages for the gethostbyname function, the ypbind and named daemons,
the
resolver functions, and the hosts, svc.conf, nsswitch.conf, and
resolv.conf files explain host name lookups in more detail.
