Miscellaneous How-To's

Anonymous FTP Setup

 Your anonymous ftp site is completely different from your web site. When people ftp to your domain anonymously, they will see the following directories:
    bin/ dev/ etc/ incoming/ lib/ pub/
"pub" is where you should put all your anonymously accessible files.
"incoming" is for the anonymous users to upload files.

 For security the following applies:

  • Only the incoming directory can be written to anonymously
  • Subdirectories are not creatable
  • The incoming directory is not readable by people dropping files there

 You are responsible for any "pirated" software uploaded by the anonymous users. The anonymous ftp sites will be periodically monitored for any abuses.
You may ignore the other directories.

Access Via The Web
 To access the anonymous FTP site via the web, use the following

 Your HTML to download a file called mirc511s.exe from a webpage would look like this:
 <A HREF="">Download Mirc Now</A>

 You should tell your visitors that they may need to right-click on the link if they are PC users, or if they use a Macintosh, they need to hold down the mouse button on the link, then select the appropriate option  from the Pop-up menu.

 Please note it's possible during peak hours to receive a "too many anonymous users error", We must restrict the number of simultaneous anonymous users to keep the webserver and normal FTP performance within normal limits. If you receive this error often you may want to put you downloadable files in your main web directory and link to them with an http call
 This assumes the zip files are in the main web directory.

 Note - if your customer experiences slow download performance, chances are it's a problem on the internet. We maintain a large margin of available bandwidth so bottlenecks never occur within our network. Please feel free to send an inquiry to be sure all the servers are operating properly, if you include there ISP's IP# we will run traceroutes to see where the delays are occurring.

Password Protected Web Directory
 NOTE: This feature is not installed on new sites, password protecting a subdirectory can now be done with the PlusMail control panel.

Virtual Publisher Security System (for qualifying accounts).
To password protect different directories on your domain you can use the Virtual Publisher Security System (for qualifying accounts). If you have this on your account, the administrator's page with directions and forms for entering new directories and users is found at:

Netscape or Internet Explorer
 Using Netscape or Internet Explorer, you can create secure
 directories and add users and passwords. The admin page is very
 simple to use. Just avoid adding groups or users with spaces in their
 names as this produces errors.

Note for Front Page users: The password administration script works poorly on FrontPage for sites. You will still receive it installed by default but we cannot provide any support if you choose to use it. Below are some guidelines you should follow. It is very important that any directory you are trying to protect be world readable and Writable. This is done by the following Unix command: chmod 777 directory-name. The main directory and any subdirectories will need to be changed in this way. Also make the /password directory chmod -R 777.

Setting up Your Own "404:File Not Found" Error Page
 A file already exists in the www directory of your server. It's called missing.html. You can edit it to your liking, or create your own. As long as it's called missing.html and it's in your root www directory, the server will display it whenever someone tries to access a page on your domain that does not exist.

Long File Names
There is no limitation for the length of file names on the server. However, only names containing from 3-16 letters are legal for email accounts,  FTP accounts, and Telnet accounts.

Zip/Unzip Files
 This Unix program is compatible with the zip program for DOS and Windows. To zip files, first have the files uploaded to your server, then log into your account with Telnet. Navigate to the directory where the files are that you want to zip. 
(for instance by typing cd www then cd sounds). 
    Then type: zip myzip file1 file2 file3
This puts the files "file1", "file2", and "file3" into a new zip archive called 
On the other hand, if you had the archive"" and wanted to get back the files, you would type: unzip myzip

 Typing zip or unzip by itself will give you a usage summary, showing nearly all the options available.
