site_verify.pl

site_verify.pl is a perl script designed to verify Grid2003 site installations from either a local or remote host. The tasks it is meant to cover are outlined at http://www.phys.ufl.edu/~prescott/grid2003/site_verify.html

Requirements/Dependencies

site_verify.pl uses a number of perl modules to collect and analyze information. One of the modules, Net::LDAP, is not packaged with the perl distribution itself, and is generally as a separate package. Depending upon your system installation, it and its dependencies may already be installed or it may not be.

site_verify.pl also relies upon a local installation of the Globus Toolkit and a valid grid proxy to perform tests requiring authentication. If no proxy exists for the user running the script, a warning will be emitted and tests requiring authentication will be disabled.

• Globus Toolkit (tar.gz from http://www.globus.org/)
• Net::LDAP (tar.gz from http://www.cpan.org)
  • Required Dependencies
    • Convert::ASN1
  • Optional Dependencies (not needed to run site_verify.pl):
    • URI
    • URI::ldap
    • Digest::MD5
    • IO::Socket::SSL
    • XML::SAX::Base
    • MIME::Base64
    • Authen::SASL

If Net::LDAP is not available to you by default, you have a few options.

• Get your system administrator to install it globally.
• Install it yourself in your own area. Generic instructions for doing this using the CPAN module are given at http://www.phys.ufl.edu/~prescott/perl_modules_normal_user.html. After following the instructions there, install Convert::ASN1 and Net::LDAP.
• Use the Net::LDAP included in the Virtual Data Toolkit. To do this, simply source the setup.csh/setup.sh from your VDT installation area.

TODO/WISHLIST

* fix display of "Hello World" errors (eg: auth ok, but stdout filename
  not created, etc.)
* subroutine-ize remaining checks
* colorize responses?  (green=good, red=bad, uncolored=neutral)
* reduce globus-job-run calls (directory existence, space, write)
* add "--vo=..." to allow filtering by sponsoring VO (MDS-reported)
* add "--jobmanager=..." to allow globus-job-run commands to use
  a user-specified jobmanager.
