They work well for this purpose though. The USB2KVM device mentioned earlier on in this thread is exactly what I was looking for, but I couldn't find a distributer locally and UPS quoted me $356 just for freight, excluding import duties in our country, so I think I'll stick with the spider KVM over IP's for now. They're about 50% cheaper locally than the KVM2USB before shipment & import duties. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532 _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
