Selecting an ISP and Getting Connected

Introduction

The business of an Internet Service Provider is, amongst other things, providing its customers with dialup connection to the Internet. If you want to be able to access "University Only" web pages, you need an ISP whose service works with the University's inbound proxy server. Table 1 lists several ISPs whose services have been tested by ITS with the inbound proxy.

Inclusion of an ISP in this list doesn't imply a recommendation - it simply means we've tested their service and it works with the inbound proxy. Similarly, the absence of an ISP from the table doesn't mean that the University has a negative opinion about their service: it simply means that we haven't tested them, or we haven't tested them succesfully.

There are two ways an ISP can be setup which will allow you to use the inbound proxy. Either they don't force you to use their own proxy, or they have set their proxy up so that it sends requests for University pages to the inbound proxy. In the first case, you will need to set your Web browser (which is probably Netscape or Microsoft Internet Explorer) to use Automatic Proxy Configuration using http://www.unimelb.edu.au/cgi-bin/ibproxy.pac as the configuration URL (Auto Config method). In the latter case, the ISP's proxy takes care of using the inbound proxy for you (ISP's Proxy method). The method tested for each ISP is noted in the table.

For detailed instructions on setting browsers up to use the inbound proxy, see http://www.its.unimelb.edu.au/ibproxy/.

The table is not comprehensive, and is only accurate to the best of our knowledge at the time of writing. It is provided as a guide only, and you should check the details with your chosen ISP before committing yourself.

Most dialin ISPs offer service on the basis that they will charge your credit card each month for a set amount, which provides a certain number of hours connection, and extra hours are available at extra cost. These accounts can usually be set up very quickly over the phone or on the Web. If you don't have a credit card, you can buy prepaid access over the counter from some ISPs, and some will be willing to bill you each month (they may require a deposit).

The services tested were standard "home-user" services.

You can usually use more hours than specified by your pricing plan, at an additional charge which is usually a bit more each hour than the "package" hours. Unused hours in your package each month are usually lost, so it pays to choose a package which matches your actual use patterns. Most ISPs will let you switch easily between pricing plans.

Note (1): It's possible for your inbound proxy authentication to expire after about an hour. If that happens, you may find that you can't access some web pages. Quitting your Web browser and re-launching it should solve the problem.

Note (2): If you revisit restricted pages in a later session, it's possible that the inbound proxy won't be consulted (i.e., if the page you visit is served from the cache on your hard disk) and you may experience some difficulty. Quitting your Web browser and re-launching it may solve the problem, and a second useful strategy is to hold down the shift key while clicking on Netscape's "Reload" button. This forces the system to get you the page from the relevant webserver, thus triggering the authentication process.


Things to Consider When Choosing an ISP

The University does not have a "favourite" ISP. There are many different services available from the ISPs listed above, and which one is best depends on a lot of things which are different for different students. You should investigate the offerings from each ISP, and make the choice you think is best for your particular circumstances. You may even choose to use more than one ISP, depending on, say, whether you are in Melbourne (term-time) or somewhere else (vacations). Here are some things to consider.


Getting Connected

Most ISPs will provide you with a kit to get started, and it will usually contain a CD with everything you need, and a technical support number to call if things go wrong. Usually, this works fine. But be careful - if you share a computer with other people (your family, for example), you can interfere with their ISP setup by installing your own. Make sure that anyone you share the computer with knows what you're doing. Recent operating systems let you keep several different internet setups on the one computer and to switch easily between them. Check the manuals!

If you go with the automatic setup procedure, you won't need to know much about the internet setup, but you may still need to set your Web browser's proxy server. If you do the setup yourself, you'll need to find out the required configuration from the ISP - by phone or by looking at their website. The settings we used in our testing are provided below.


Internet Access Settings and Pricing Summaries

It's important to understand the difference between your University username and password, and your ISP username and password. They probably won't be the same, and when you have to supply a username or password, you have to give the right one. In the table above, words like its-username mean the username given to you by the University. Similary, ozemail-password means your ozemail password, and so on.

Pricing summaries were accurate at the time of writing each summary, but please be aware that things change: the date of each summary is not necessarily the same as the date of this document. Check the ISPs' own web pages for more detailed and up to date information maintained by the ISPs themselves.


If it doesn't work

When you use the University network via an ISP, you're using a range of services provided by the ISP and by (possibly several) parts of the University. You'll help everyone, including yourself, if you try to work out what's going wrong so that you can contact the right people for help. Table 2 gives some guidelines.

Don't get asked for username and password and so can't access University-only web pages Check the proxy setting in your browser. If it's correct, and you're using an ISP from Table 1, contact ITS. Otherwise, contact your ISP.
