THE VIRTUAL SERVER HANDBOOK
Advise your users to change passwords frequently. Changing passwords
lessens the likelihood that malicious users can access your virtual server.
Characteristics of good passwords include:
Length (traditional UNIX systems recognize and use the first eight
characters of the password).
Complexity (UNIX passwords are case sensitive, and can contain
unusual characters).
Obscurity (never use a password that incorporates personal information
about yourself or family).
For example:
De76sAf4
The above password has mixed case, numbers, no personal information and
is not a regular word. This makes the password more secure.
Managing E mail accounts
Besides adding users, you can use "vadduser" to edit existing accounts.
To remove E mail service from an existing account without
removing the user
1.
From the command prompt, enter
vadduser
. This action launches the
vadduser program that proceeds through a series of prompts.
2.
At option number 4, "Account Services," type
E mail
to remove the
users E mail service or type
ftp
to remove FTP services.
3.
Continue through the rest of the prompts.
To remove E mail account
1.
From the command prompt, enter
vrmuser
. This action launches the
vrmuser program that proceeds through a series of prompts.
2.
Enter the account name to remove. This action removes the entire
account except the user's home directory and contents (remove these
items manually, if necessary).
If the account is only being used to receive mail then perhaps it makes sense
to remove the account entirely when removing the mailbox.
To list E mail mailboxes
From the command prompt, enter vlistuser. This action displays a report
with the following account information about each user:
Account name
Account owner
Home directory
Service list (with associated quotas)
Note: The absence of a dash ( ) in the mail quota column indicates that
the account has an E mail mailbox, (meaning the account is enabled to
receive incoming mail).
