The first thing you will require is the website “FTP” details, these are available from you provider (whoever is hosting the website). These should consist of three things:
3) FTP Location e.g. ftp.mydomain.com
Once you have these you will require an FTP client software, a good example of this (free) would be Filezilla (http://filezilla-project.org/). Simply download and detonate the installer and then follow the on-screen prompts.
You are now in a position to “Downlad” the website code from the FTP server.
1) Open FileZilla or other FTP application
2) In the case of Filezilla enter your ftp location, username and password in the boxes at the top and then click connect.
3) You will see the FTP windows just below, the right hand side shows the contents on the Internet and the left hand side shows the local information.
4) Highlight everything in the right hand window (in the same way you do in windows explorer)
5) Navigate in the left hand side window to where you would like to store the downloaded content.
6) Right click on the highlighted files and folders on the right hand side and click download.
7) This will now start to do things, and download each file one by one to the location you have specified on the right hand side. Now you are going to need an HTML editing application, you can simply use Notepad but I would suggest “Bluefish” (Free) which is an excellent application that is available on both Linux and Windows. The Bluefish Project is located at http://bluefish.openoffice.nl/ simply click the download link and read the instructions for your operating system. In the case of Fedora (not familiar with others) you can use the package installer, or issue a yum install bluefish command.
Open Bluefish, select file open and then navigate to the location you specified to download your content to in the previous steps. The main file (Homepage) will usually be called index.htm, index.html, default.htm or default.html but could be anything. Once opened make your changes in the main window and click file save to save. There are many hundreds of great HTML programming guides on the internet a good example is http://www.utoronto.ca/webdocs/HTMLdocs/NewHTML. But the safest thing to do is to try things out on a test website.
Remember this is an offline data set we are fiddling with, so if you do make a complete hash of it, then simply go back to filezilla and re-download the page in question.
