{{Admon/tip|Performing this Lab off the Seneca network (eg. at home)|'''It is recommended to perform this lab in one of Seneca College's labs'''. This lab uses servers which are on the Seneca network and which are not available from other locations (such as your home). If you attempt this lab from another location, adjust the belmont.senecac.on.ca URLs to point to another mirror server -- note that you may need to change the directory name as well as the server name. The installation of the '''centos3''' virtual machine <u>must</u> be done at Seneca.}}
