NAME

Listgroup.pm - Lists hosts/users in a netgroup group.

SYNOPSIS

    use Listgroup;

    $array_ref_groups = listgroup();
    $array_ref_groups = listgroups();

    $array_ref_users_or_groups = listgroup({groupname});

    $array_ref_users_or_groups = listgroup_user({groupname1}, 
            [ [-]{groupname2}, [-]{gropuname3} ]);

    $array_ref_users_or_groups = listgroup_host({groupname1}, 
            [ [-]{groupname2}, [-]{gropuname3} ]);

DESCRIPTION

A library used to get groups or members of a netgroup NIS map. listgroup() without any parameters or listgroups() lists all the available netgroup groups.

With groupname parameters listgroup, listgroup_user, listgroup_host will recusively list the members of the named groups. If the groupname is preceded with a - members of that group will be excluded from the returned list. Each member in a group is a triplet of (host,user,domain). The host portion or user portion of the members is returned by listgroup_host() and listgroup(), the user portion of the members is returned by listgroup_user().

REQUIRES

Net::NIS

PUBLIC METHODS

listgroups

    $array_ref_groups = listgroups();

Returns a reference to an array of groups from the netgroup nis map.

listgroup_host, listgroup

    $array_ref_users_or_groups = listgroup({groupname1}, 
            [ [-]{groupname2}, [-]{gropuname3} ]);

    $array_ref_users_or_groups = listgroup_host({groupname1}, 
            [ [-]{groupname2}, [-]{gropuname3} ]);

Returns a reference to an array of the host portion of the members of the provided groups. Members of groupnames preceded by a - will be excluded from the returned list.

Groups are processed in the order they appear in the parameter list.

If the NIS map 'netgroup' does not exist or another fatal NIS error occurs, die will be called. Wrap this call in an eval if you want to catch that type of error.

listgroup_user

    $array_ref_users_or_groups = listgroup_user({groupname1}, 
            [ [-]{groupname2}, [-]{gropuname3} ]);

Returns a reference to an array of the user portion of the members of the provided groups. Members of groupnames preceded by a - will be excluded from the returned list.

Groups are processed in the order they appear in the parameter list.

If the NIS map 'netgroup' does not exist or another fatal NIS error occurs, die will be called. Wrap this call in an eval if you want to catch that type of error.
