Information Provider Haven
PPP Access and Offline Viewing of Web Pages
As most CCN users already know, you cannot use browsers such as Netscape or
Internet Explorer with the Chebucto Community Net. We simply do not have the
necessary PPP (Point to Point Protocol) connections in place that these programs use
to connect to the internet.
Part of the reason why CCN does not offer widespread PPP access is a legacy from
the time of its creation, a time when internet connections were harder to come by and
system resources were costly. Also the philosophy of CCN is that we are here to provide
net access to anyone with the ability to connect to us, which means we support terminal
emulations and slow modem speeds run on computers which could not connect to the
internet in any other way on any other provider. This will not be changing in the future.
However, as CCN Board Chair Peter Morgan has commented, "if Chebucto were
to be started up today, we would be a PPP system". There is a move afoot to bring PPP
to Chebucto. You would be able to use any application you can use with any other
Internet Service Provider (ISP); Netscape and Internet Explorer browsers, FTP
programs, the whole gamut of internet software.
Of course there are limits to this. We are not a commercial ISP and lack the
resources and the desire to compete with them. We are a volunteer-run organization
with limited funds and the equipment necessary to support PPP access is costly. Phone
lines would need to be added, a more expensive type of faster output modem purchased
for each user connection and money would have to be found to pay for all this. As a
result the CCN Board has decided that the first PPP modems will be for CCN
Information Provider use.
Currently there are four modems dedicated to PPP on a test basis with the
potential to have another twenty with the current PortMaster
Communications Server. Download speeds rival
those of the commercial ISPs. A committee has been struck to determine how PPP will
be administered and their tentative conclusion is that CCN IPs will be divided into five
new categories. Please note that no final decisions have been made on anything yet so
these categories are not set in stone. No dollar figures have been finalized so amounts
are not listed here.
Category I: Basic IP level
Cost: contribution to CCN at a level affordable to the organization.
Service: as now provided with volunteer training and support, 2 mailing lists but
with a limit (to be determined) on disk space.
Category II: IP Member
Cost: $xxx (to be determined)
Service: as above with no limit on disk space. PPP access.
Category III: IP Member with virtual domain
Cost: $xxx+
Service: as above with a virtual domain provided and an "organizational" email
address. PPP access.
Category IV: IP Member with basic package
Cost: $xxx++
Service: as above with 10 email addresses, minimum level of "contracted" or
"staff" support provided to organization; organization is responsible for all usage
(content, email and lists). PPP access.
Category V: IP Member with network package
Cost: $xxxx
Service: as above with 20 email addresses, 4 mailing lists, higher level of "staff" or
"contracted" support provided to organization; organization is responsible for all usage
(content, email and lists). PPP access.
Once again, these categories have not been finalized and are subject to change.
In the meanwhile, one of the most common reasons given for IPs wanting PPP
access is so that they might check out how their pages look on a graphic browser. It is
also possible to do this on your own home computer. Both Netscape and Internet
Explorer will view HTML files right on your own hard drive. Simply type in the location
as: DRIVELETTER:/DIRECTORYNAME/FILENAME.HTM and your web page will be
displayed. Let's say you have have a directory on your C:\ drive called CCN where you
keep your web pages. In it you have a page called MAINPAGE.HTM. You would type
this in the location window to see the page: C:/CCN/MAINPAGE.HTM
If you have made links to other web pages in the same directory and your links are
"local" links rather than "full" links, then these links will still work on your hard drive. A
"local" link is one that looks like this:
<a href="EXAMPLE.HTML">
Go to this example page
</a>
while a "full" link is one like this:
<a href="http://www.chebucto.ns.ca/my_site/example.html">
Go to this example page
</a>
Of course links referring to pages on other sites will not work when the page is
being read offline on your hard drive, but these links may be tested online on CCN with
the Lynx text-only browser to ensure they work.
Remember when you are referring to files in links that filenames on servers like
CCN are name and case sensitive. "Example.html"
and "Example.htm" are the same
thing to Netscape reading a "local" link on your hard drive but will be two different files
online so a link referring to "example.htm" will not take you to the
file "example.html"
online. Online on CCN "Example.html", "example.html",
"Example.htm" and
"example.htm" will be four different files so remember
to have your links refer to the exact filename.
The same thing applies to your web page graphics - "local" links will work and
your graphics will show up on the page as they would online. Just remember to keep
the name exact - same extension, same case.
A "local" graphic can be in a different directory, too
(as can a "local" web page link).
Example 1: Graphic is in a subdirectory called "pix"
<img src="pix/example.jpg">
Example 2: Graphic is in the next higher level directory
<img src="../example.jpg">
Example 3: Graphic is in a different directory called "pix"
but this directory is on the same level as the web page's "home" directory
<img src="../pix/example.jpg">
By using "local" references to your web page's graphics and the links to the other
pages on your site, you can navigate within your site offline using a graphical browser
reading the pages off your hard drive and they will appear just as they would online.
