Instant-Grid 1.1 (Default branch)
Instant-Grid is a Knoppix-based live-CD bundledwith a pre-configured grid environment based onthe Globus Toolkit. One PC started from this CDbecomes the Instant-Grid frontend. It alsofunctions as a PXE boot-server, allowing other PCsin the same local network to boot the Instant-Gridenvironment. Together with the frontend, these PCsautomatically form a working test grid. Like withthe original Knoppix, the existing configurationof the participating PC is not touched (exceptmaybe for enabling the PXE boot-option), andremains instantly available by a simple reboot.License: Freely DistributableChanges:
This version is based on Knoppix 5.1.1, which improves support for more recent hardware. The English documentation has been expanded, many function tests have been automated, and the workflow stability has been improved.Image

GLOBUS-K5(8)							  Globus Toolkit						      GLOBUS-K5(8)

NAME

       globus-k5 - Acquire Kerberos Credentials for use with Grid Services

SYNOPSIS

       globus-k5 SERVICE-COMMAND [SERVICE-ARGS...]

DESCRIPTION

       The globus-k5 program is an authorization module used by the globus-gatekeeper program to acquire Kerberos 5 Credentials prior to executing
       a Grid Service. This may be accomplished by running kinit with a password stored in the globuskmap file, using the NCSA krb525 command, or
       the sslk5 command to use the X509 user proxy.

       The arguments passed to globus-k5 will not be used by it, but will be passed onto the job manager. The first parameter must be the path to
       the Grid Service.

       It is expected that the environment will contain the variables GLOBUSID and USER for the Grid and local POSIX user identities. This program
       is normally run as root, and will call seteuid() prior to executing the Grid Service.

       The parameters to use and the mapping for the globus to K5 user are located in the globuskmap file.

FORMAT OF THE GLOBUSKMAP FILE

       The globuskmap file is a line-oriented file which each line containing a command to run to acquire Kerberos 5 credentials for a Grid
       identity. Each line consists of an optionally-quoted GLOBUSID value followed by a command-line for running a process to acquire a Kerberos
       credential. For example:

	   "/O=Example/OU=Grid/CN=Joe User" /usr/afsws/bin/klog -principal juser -password mypasswd -cell infn.it

ENVIRONMENT

       If the following variables affect the execution of globus-k5:

       GLOBUSKMAP
	   Path to the globuskmap file.

       USER
	   POSIX username that the service will run as.

       KRB5CCNAME
	   Path to a Kerberos credential cache.

       GLOBUS_ID
	   Grid identity to generate Kerberos credentials for.

FILES

       /etc/globuskmap
	   Default file mapping Grid identities to Kerberos 5 principals.
