This is a compilation of questions frequently asked about web-based services on Grex.
This includes GIF, JPEG, WAV, AU, AIFF, MPEG, MOV, and possibly other formats, even if they are small.
This means that you cannot write scripts, process forms, or implement gateways or counters locally.
We do permit incidental commercial use such as an individual selling shareware, as long as it does not generate too much traffic.
If activity on your site starts to approach 1 MB/day, we will ask you to look for another site. Our link can only stand so much. It is very slow. You will get plenty of warning in this event.

Once you have your account, and you can log in to Grex via telnet, then you run the "mkhomepage" program. This program gives you the option of creating a prototype home page. If your shell is not a unix shell, you must type a ! before the mkhomepage in order to run it.

Fortunately, it is rather simple to learn the basics of HTML Carl Miller wrote a basic introduction to hypertext and for a more complete explanation of HTML tags, there is a wealth of information on the net. Yahoo maintains an extensive list of HTML tutorials and guides. In the bookstore, you might want to pick up a copy of Web Publishing with HTML by Laura Lemay,. Sams.net ($29.99).

Each page will have a different URL. Your home page can be found at http://www.cyberspace.org/~youraccount/ and any other page can be found at http://www.cyberspace.org/~youraccount/filename.
For links between the pages of your site, it is best to use
relative links in your hypertext links. This means you should not
link to a file using the full URL, like this:
<a
href="http://www.cyberspace.org/~youraccount/filename">,
but rather you should use the much simpler form <a
href=filename>. Of course you must use the full link in a
pointer from another site.

If you use lynx on Grex, you can view any page with it that you have read access to. That is because lynx is reading the page directly. If you try to access the page via Grex's web server, the page must be located in the www directory or it will not be visible.
If a page named foo.html is in your www directory, its full path is ~youraccount/www/foo.html, but the URL for it has no "www" because it is assumed by the web server that files must be in the www directory. So its URL would be http://www.cyberspace.org/~youraccount/foo.html.
URLs of the form http://www.cyberspace.org/a/y/o/youraccount/www/foo.html do not work.
If you have changed the permissions on either your home directory or your www directory to "700" , the web server will not be able to see your files. Both your home directory and www directory must have at least the "x" bit set, or your pages will not be visible on the web. Use permissions of "711" on each directory if you do not wish to allow other people to see what files are there, and use "755" if you do. "700" will render your files inaccessible.

Remember to log into grex with your account and password. Grex does not support anonymous ftp.
Also remember to put the files into your www directory, not your home directory.
If you dial into grex directly, use a file transfer protocol such as sz or kermit to move the files to your www directory.

You can get around this limitation if you have access to another web server. If you have an image or any other multimedia file which can be found on another web server, you can put a pointer to it in a page on Grex. Since this does not require shipping out the image over Grex's internet link, there is no problem with using this technique.
In fact, if you have a graphical web browser, you may have noticed that the Grex logo is prominently displayed on Grex's home page. This image is not stored on Grex itself, but rather it is stored on the HVCN web server.

http://www.cyberspace.org/cgi-bin/bt/peek:agoraJust replace the name "agora" with whatever conference you want to link to.
This will put anyone who clicks it into the conference via Backtalk. They will be in read-only mode, so people without Grex accounts will be able to look at the conference. If they are using a non-graphical browser like lynx, it will put them in the vanilla interface. Otherwise the pistachio interface is used.
You can also link to a specific item in a conference. Below is the URL for a link to item 2 in the agora conference:
http://www.cyberspace.org/cgi-bin/bt/peek:agora:2Or you can link to a specific response to a specific item. Here is a link to response 8 of item 1 in the agora conference:
http://www.cyberspace.org/cgi-bin/bt/peek:agora:1:8You can also link to ranges of responses. The following URL links to responses 0 (that's the item text), 3, and 7 through 12 of item one of the agora conference:
http://www.cyberspace.org/cgi-bin/bt/peek:agora:1:0,3,7-12
