HOSTNAMEUTILS(1) Sun Grid Engine User Commands HOSTNAMEUTILS(1) NAME
sge_hostnameutils.1 - SGE Host name utilities gethostname - get local hostname. gethostbyname - get local host information for specified hostname. gethostbyaddr - get hostname via IP address. getservbyname - get configured port number of service SYNTAX
gethostname [-help|-name|-aname|-all] gethostbyname [-help|-name|-aname|-all] <name> gethostbyaddr [-help|-name|-aname|-all] <ip> getservbyname [-help|-number] <service> DESCRIPTION
gethostname and gethostbyname are used to get the local resolved host name. gethostbyaddr is used to get the hostname of a specified IP address (dotted decimal notation). getservbyname can be used to get the configured port number of a service (e.g. from /etc/services). The hostname utils are primarily used by the Sun Grid Engine installation scripts. gethostname , gethostbyname and gethostbyaddr called without any option will print out the hostname, all specified aliases, and the IP address of the locally resolved hostname. Calling get- servbyname without any option will print out the full service entry. OPTIONS
-help Prints a list of all options. -name This option only reports the primary name of the host. -aname If this option is set, the Sun Grid Engine host alias file is used for host name resolving. It is necessary to set the environment variable SGE_ROOT and, if more than one cell is defined, also SGE_CELL. This option will print out the Sun Grid Engine host name. -all By using the -all option all available host information will be printed. This information includes the host name, the Sun Grid Engine host name, all host aliases, and the IP address of the host. -number This option will print out the port number of the specified service name. <name> The host name for which the information is requested. <ip> The IP address (dotted decimal notation) for which the information is requested. <service> The service name for which the information is requested (e.g. ftp, sge_qmaster or sge_execd). EXAMPLES
The following example shows how to get the port number of the FTP service: >getservbyname -number ftp 21 The next example shows the output of gethostname -all when the host alias file contains this line: gridmaster extern_name extern_name.mydomain The local host resolving must also provide the alias name "gridmaster". Each Sun Grid Engine host that wants to use the cluster must be able to resolve the host name "gridmaster". To setup an alias name, edit your /etc/hosts file or modify your NIS setup to provide the alias for the NIS clients. The host alias file must be readable from each host (use e.g. NFS shared file location). >gethostname -all Hostname: extern_name.mydomain SGE name: gridmaster Aliases: loghost gridmaster Host Address(es): 192.168.143.99 ENVIRONMENTAL VARIABLES
SGE_ROOT Specifies the location of the Sun Grid Engine standard configuration files. SGE_CELL If set, specifies the default Sun Grid Engine cell. SEE ALSO
