managegroups.py is a script for remotely managing VCL user groups. It uses VCL's XML RPC API to provide an easy command line driven way of doing group management.

NOTE: This script does not work with python 2.7. It relies on the xmlrpclib module which changed from 2.6 to 2.7 in a way that broke the script. You need to use python 2.6 for it to work.

Download information

managegroups.py is not included in any official releases. You can download it from our subversion repository.

Available Commands

Running managegroups.py with no arguments provides help on how to use it. It is used by specifying one of the following commands along with parameters specific to each command.

Return Status

These are the possible values of the return status:

  • 0 - successful execution
  • 1 - missing authentication information
  • 2 - problem with command line parameters
  • 3 - for commands that pass in a filename, problems encountered reading the file
  • 4 - no users specified to add to or remove from a group
  • 5 - error encountered while performing XML RPC API call

Return Output

The output of managegroups.py will always start with one of:

  • SUCCESS: - indicates successful run of the command
  • ERROR: - indicates a problem running the command
  • WARNING: - indicates a no errors, but possibly unexpected results (i.e. specifying a file when adding users to a group, but the file is empty)
    There is one exception. If you specify a parameter, but omit the argument for it, the option parser used in the script will generate an error. However, in those cases, the return status of the command will always be 2.

Authentication

The script needs to know what userid/password to use and what URL to access. These can either be defined as variables within the script (look at the very top of the file) or specified as parameters on the command line, before specifying which of managegroups's commands to use.

There are two ways to specify authentication information because some people may prefer to have the password saved in the file, but not in a command line history, while others may prefer to have the password saved in command line history, but not in the file. Any of the authentication options specified on the command line will override any defined in the file.

The options for specifying authentication on the command line are

  • -u username - log in to VCL site with this user, must be in username@affiliation form
  • -p "vclpass" - password used when logging in to VCL site, use quotes if it contains spaces
  • -r vclurl - XMLRPC URL of VCL site (it will end with index.php?mode=xmlrpccall - i.e. https://vcl.ncsu.edu/scheduling/index.php?mode=xmlrpccall)

Examples

The last example includes the authentication information on the command line. For the other examples, the authentication would have been specified inline in the script. Authentication information was only included in one example to make the others more readable.

Create a new user group with name FallUsers, affiliation Local, admin as the owner, and adminUsers@Local as the managing group:

Code Block
managegroups.py addUserGroup -n FallUsers -a Local -o admin@Local -m adminUsers@Local -i 240 -t 360 -x 30

Change the name of an existing user group named FallUsers, affiliation Local to be SpringUsers:

Code Block
managegroups.py editUserGroup -n FallUsers -a Local -N SpringUsers

Add two users specified on the command line to a group:

Code Block
managegroups.py addUsersToGroup -n FallUsers -a Local -l student1<at:var at:name="Local,student2" />Local

Add all users in a specified file to a group:

Code Block
managegroups.py addUsersToGroup -n FallUsers -a Local -f newusers.txt

The file would contain something like the following:

Code Block
userid1@Local
userid2@Local
userid3@Local

Remove all members of a group:

Code Block
managegroups.py emptyGroupMembership -n CS101 -a Local

Delete a user group:

Code Block
managegroups.py -u admin@Local -p passwordhere -r 'https://your.vcl.site/index.php?mode=xmlrpccall' deleteUserGroup -n CS101 -a Local
