One of the most basic
tasks you will need to perform as a Virtual
Server Administrator is uploading files to your
website. In most cases you will upload your
content using File Transfer
Protocol or FTP. You can alternatively upload
content using a web content publisher.
Many
web content authoring programs include built-in
web publishing capability. In some cases this
involves installing proprietary extensions on the
Virtual Server (a la Microsoft FrontPage), other
packages use the HTTP "PUT" method, but
more commonly publishers will provide support for
simple FTP. It is not necessary, however, to rely
on your web content authoring program to publish
to your site. You can compose your web content
using any program and then FTP the content to
your Virtual Server manually.
This
page discusses the general information you will
need to know to FTP content to your Virtual
Server. More detailed steps are given to use
several sepecific FTP clients. And, uploading
content via other methods is also presented. The
sections on the page are show below:
General
Instructions for using an FTP Client
Using an FTP client to upload content to your
Virtual Server is a very simple process. The
following guidelines provide a general overview
of uploading files to your Virtual Server.
- You
will need an ftp client for your local
machine. You can find many free and
useful clients on the Internet. Search
for "FTP client" in your
favorite search engine- you will likely
be overwhelmed by the amount of FTP
clients available.
If you
use Windows, we have found WS_FTP to be
very useful. For the Macintosh OS, Fetch is the
most popular (and friendliest) FTP client
available. Detailed FTP instructions for
both of these popular FTP clients is
given below.
- Connect
to your Virtual Server via FTP using your
login id and your login
password that you received from Nihil
Ultra. Do not login as anonymous, as you
will not have access to the directories
and files you need.
- When
you login to your Virtual Server, you
will be placed in your home directory
(/usr/home/login_id). This is the
same directory you find yourself in when
you telnet to your Virtual Server.
- All
html documents and graphics should be
uploaded to the usr/local/etc/httpd/htdocs
directory. Here you will find a file
titled "index.html" - this is
the default page that is displayed when
you access your web site with a browser.
You may upload your html documents and
graphics to the usr/local/etc/httpd/htdocs
directory, or into any subdirectory under
the htdocs directory.
If you
transfer a file named test.htm to
your htdocs directory, you can
access that file using the following URL
- http://www.your-domain.name/test.htm.
If you make a subdirectory titled "documents"
in your htdocs directory, and then
transfer a file called info.html
to that directory, it can then be
accessed by the URL - http://www.your-domain.name/documents/info.html
NOTE:
If you do not want to use the filename
"index.html" as your your
default page you can do one of three
things:
- upload
your home page file (e.g.
default.htm) into the htdocs
directory, and then rename it to
"index.html"
- establish
a symbolic link to the file you
uploaded to the htdocs directory
(e.g. default.htm) by typing the
following command:
ln -s default.htm index.html
- change
the DirectoryIndex definition in
the ~/www/conf/httpd.conf
file on your Virtual Server (or
the ~/www/conf/srm.conf
file, if you Virtual Server was
configured before Dec. 8, 1998)
from index.html to the new name
(e.g. default.htm).
- IMPORTANT:
Be sure you ftp all your HTML files, as
well as any text files such as cgi script
source code in ASCII
format! All your image files need to be
tranferred in BINARY
format. Your FTP program should allow you
to select the file transfer mode, either
ASCII or BINARY. Most FTP clients have an
"Automatic" transfer mode
option that can be set - when this option
is selected the FTP client will
automatically determine which file
transfer mode to use when you upload or
download files.
Uploading
Files Using WS_FTP (MS Windows)
If you are using MS Windows, WS_FTP is an extremely
friendly, intuitive and easy-to-use client.
Specific instructions about how to use WS_FTP are
included below:
- Establish a
connection to your Virtual Server by
selecting the "Connect" button.
Specify your company name as the
"Profile Name", your domain
name (or temporary domain name if your
domain name has not yet been registered)
as the "Host Name/Address",
your login name as the "User
ID", and your login password as the
"Password".
- Once a connection
is established, two columns will appear
on your screen. The column on the left
displays files on your computer while the
column on the right represents
directories and files on your Virtual
Server.
- You will want to
navigate to the "www/htdocs" or
"usr/local/etc/httpd/htdocs"
folder on your Virtual Server (the right
side of the dialog). This is the
directory where you will store your web
content.
- Select the
appropriate files or directories that you
want to transfer from your computer (the
left side) to your Virtual Server (the
right side) by selecting them with your
mouse. You can select more than one by
holding down the shift key.
- Once these files
are selected you simply hit the arrow
"-->" pointing toward the
right or toward the Virtual Server
directory window. Be sure that all HTML
documents and cgi script are transferred
in ASCII mode. Graphics should be
transferred in Binary format. The latest
versions of WS_FTP provide an
"Auto" toggle button you can
select- WS_FTP will then automatically
determine which mode to transfer the file
(we recommend you use the
"Auto" mode).
Uploading
Files Using Fetch (Macintosh)
If you are using a Macintosh, Fetch is probably the
most popular FTP program available and is quite
easy to use. Specific instructions about how to
use Fetch are included below:
- Establish a
connection to your Virtual Server by
selecting the "New Connection"
button under the "File" menu.
Specify your domain name (or temporary
domain name if your domain name has not
yet been registered) as the
"Host", your login name as the
"User ID", and your login
password as the "Password".
- You will want to
navigate to the "www/htdocs" or
"usr/local/etc/httpd/htdocs"
folder on your Virtual Server. This is
the directory where you will store your
web content.
- To upload content
to your Virtual server you can either
drag files and folders from your desktop
to the Fetch window or select the
"Put File..." button and select
files and folders.
- Be sure that all
HTML documents and cgi script are
transferred in ASCII mode. Graphics
should be transferred in Binary format.
Fetch also has a setting,
"Automatic", that you can
select- Fetch will then automatically
determine which mode to transfer the file
(we recommend you use the
"Automatic" mode).
Using
a Console FTP Client
Most operating systems (UNIX, NT, Windows 95) are
shipped with a built-in FTP client that is
accessed from a "console window". Many
people don't use a console FTP client partly
because they don't know one exists and partly
because console FTP clients have a steeper
learning curve. One you use, learn, and master a
console FTP client you will very likely never use
a graphical FTP client again. (It sounds crazy,
but it's true for many people).
To use
a console FTP client you will first need access
to a "command prompt". This can be
gained by opening a console window. You can do
this in Windows 95/NT by looking in your
"Start->Program" menu for
"MS-DOS prompt" or "Command
Prompt". You can also "Run" the
command prompt executable by selecting
"Start->Run" and entering the
executable path
"c:/windows/command/command.com" or
"c:/winnt/system32/cmd.exe" (as the
case may be).
Most
UNIX environments use console windows and command
prompts quite extensively and UNIX users are
already comfortable using them (or should be).
When you Telnet or SSH to your Virtual Server you
are effectively open a command prompt remotely on
your Virtual Server. So you can, in effect, use
FTP from a command prompt on your Virtual Server
to download a file from another remote host
directly to your Virtual Server. For example, you
may want to download software from XYZ, Inc.
(ftp.xyz.com) and install the software on your
Virtual Server. Instead of downloading the
software from XYZ, Inc. to your office computer
and then uploading it from your office computer
to your Virtual Server (which can be quite slow
on a 28.8), you can telnet to your Virtual Server
and FTP the software from XYZ, Inc. directly to
your Virtual Server (using high speed DS3's).
Now
that you understand console windows and command
prompts (or more specifically how to gain access
to one), you need to understand how to use a
console FTP client. To open up an FTP session at
a command prompt simply type "ftp [remote
host]", where [remote host] is the site
you are attempting to contact (i.e. ftp.xyz.com).
This is where is gets fun because you know can
see what's going on "behind the scenes"
when you were using a graphical FTP client.
When
you open an FTP session with a remote host, you
will more than likely be prompted for a username
and password pair (sounds logical enough). After
you have successfully logged into the remote ftp
site, you can navigate around using the
"cd" command to change your current
working directory on the remote site. Type
"ls" or "dir" to list the
files in your current working directory on the
remote site.
To
upload from your local machine (or the machine
from which you initiated the FTP session) to the
remote host, you use the command "put".
For example, to upload a file in your local
working directory named "index.html" to
your current working directory on the remote
site, you would type "put index.html
test.html". This will transfer the file
"index.html" to the remote host and
store it under the name "test.html". If
you would like to store the local file as the
same name on the remote host simply type
something like "put index.html
index.html" or simply "put
index.html". To upload multiple files, use
the command "mput" using wildcards such
as "mput *.html". You may want
to turn off the confirm prompt by typing the
command "prompt" before you
upload multiple files.
To
download content from a remote host (or the
machine to which you opened the FTP session) to
your local machine, you use the command
"get". For example, to download a file
to your local working directory named
"test.html" from your current working
directory on the remote site, you would type
"get test.html index.html". This
will transfer the file "test.html" from
the remote host and store it under the name
"index.html" on your local computer. To
download multiple files, use the command
"mget" using wildcards such as "mget
*.html". You may want to turn off the
confirm prompt by typing the command "prompt"
before you download multiple files.
As was
mentioned in the General Instructions section, it
is important to upload and download ascii text
files such as HTML content in ASCII mode.
Likewise, binary content such as gif/jpg images
should be uploaded and downloaded in BINARY mode.
To change your upload mode to ASCII simply type
"ascii". To change your upload
mode to BINARY simply type "binary".
Other important FTP commands are summarized in
the table below. Arguments for commands are
indicated using brackets [ ]:
| ascii |
Set the file
transfer type to network ASCII. |
| binary |
Set the file
transfer type to support binary image
transfer. |
bye
quit |
Terminate the FTP
session with the remote server and exit
ftp. An end of file will also terminate
the session and exit. |
| cd |
[remote-directory]
Change the working directory on the
remote machine to remote-directory.
|
| delete |
[remote-file]
Delete the file remote-file on the
remote machine. |
dir
ls |
[remote-directory]
Print a listing of the directory contents
in the directory, remote-directory.
If no remote directory is specified, a
listing of the current working directory
on the remote machine is shown. |
| get |
[remote-file]
[local-file]
Retrieve the remote-file and store
it on the local machine. If the local
file name is not specified, it is given
the same name it has on the remote
machine. |
| help |
[command]
Print an informative message about the
meaning of command. If no argument
is given, ftp prints a list of the known
commands. |
| lcd |
[local-directory]
Change the working directory on the local
machine. If no directory is specified,
the user's current local working
directory is displayed. |
| mdelete |
[remote-files]

| mput |
[local-files]
Expand wild cards in the list of local
files given as argu- ments and do a put
for each file in the resulting list. |
| prompt |
Toggle
interactive prompting. Interactive
prompting occurs during multiple file

tively retrieve or store files. If
prompting is turned off (default is on),
any mget or mput will
transfer all files, and any mdelete
will delete all files. |
| put |
