“.univ.edu” execute programs under this user account name.
Likewise, an address of
the form: 205.238.107.* allows execution from that TCP/IP subnet. The “*” must
occur only at the beginning of host names and at the end of TCP/IP addresses. It must be
immediately followed/proceeded by a period “.”.
Example:
205.238.107.*,m1.some.com,*.xyz.gov,128.110.163.210
For best security, use only fully specified TCP/IP addresses. (I.e. don’t use host names
and don’t use wildcards.)
Additionally, you can allow a remote account with a different account name access as this
user. To do this precede the host entry with “Username@”. If you want all accounts to
access as this user from a given host, substitute a “*” for “Username”.
Example:
*@205.238.107.*,brian@ataman.com
Again, for best security, don’t use wildcards.
10.1.2 Connections Page
This page shows a list of the commands that are actively executing through the ATRLS.
The “Refresh” button is used to update the list of active connections. The “Terminate”
11
button causes the programs associated with a logon session to terminate. The “Terminate
All” button causes all current logon sessions to terminate.
10.1.3 Banners Page
This page allows you to enter text that will be displayed to telnetd/rlogind users before
and after logon.

10.1.4 Prompts Page
This page controls the presentation and text of telnetd/rlogind prompts to users.
10.1.4.1
Logon Prompt
When the Default Handling is set to “Always Ask”, the user is prompted for a logon
account name with the Prompt Text.
When the Default Handling is set to “Force Default”, the user is not prompted. The user
name listed as the Default Response will be used.
10.1.4.2
Password Prompt
When the Default Handling is set to “Always Ask”, the user is prompted for a password
with the Prompt Text.
When the Default Handling is set to “Force Default”, the user is not prompted. The
password listed as the Default Response will be used.
It is very rare that you would want to set the Default Response field for the
Password Prompt – in general, this would create a huge security hole. This feature
was provided at the request of customers who need the ability to automatically logon all
of their users to a fixed application when connecting to the telnet port.
13
10.1.4.3
Mode Prompt
For an explanation of modes, see the
Using the Rlogind and Telnetd Services
section
below.
When the Default Handling is set to “Always Ask”, the user is prompted for the mode
with the Prompt Text. If the user responds by just hitting return,
the mode listed as the
Default Response will be used. The user should choose either Simple or Advanced and hit
the return key. (Only a “s” or “a” followed by return has to be typed. Either case can be
used.)
When the Default Handling is set to “Force Default”, the user is not prompted. The mode
listed as the Default Response will be used.
10.1.4.4
Terminal Type Prompt
The Terminal Type Prompt processing occurs only if a connection uses Advanced Mode.
The ANSI terminal type should be used if your telnet/rlogin client supports the
ANSI-BBS set of terminal escape sequences. (ANSI-BBS is the same set of escape
sequences used by ANSI.SYS under DOS and also in OS/2. It uses the OEM character set
and has limited color support.) Otherwise, the VTXXX terminal type should be used.
This terminal type works with most VT100, VT102, VT220, VT320 and VT420
emulations and with the xterm program found on most Unix systems.
When the Default Handling is set to “Always Ask”, the user is prompted for a terminal
type. If the user responds by just hitting return, the mode listed as the Default Response
will be used. The user should choose either VTXXX or ANSI and hit the return key.
(Only a “v” or “a” followed by return has to be typed. Either case can be used.)
When the Default Handling is set to “Automatic”, the terminal type sent by the client
program is examined. If the terminal type begins with “ansi”, then the ANSI terminal
type is chosen. If the terminal type begins with “vt”, “dec-vt”, or “xterm” then the
VTXXX type is chosen. Terminal type comparisons are all case-insensitive. Otherwise,
the user will be prompted as in the case of “Always Ask” above. The “Automatic” style
of terminal type handling cannot be used if all other prompts have been set to “Force
Default”.
When the Default Handling is set to “Force Default”, the user is not prompted. The
terminal type listed as the Default Response will be used.

10.1.5 Advanced Page
Most users do not need to use the settings on this page.
For each service in the ATRLS:
•
“Service Port” is the TCP/IP port number the service will listen on. To disable a
service, set this field to 0 (zero).
•
“List of hosts allowed to connect” is a comma-separated list of TCP/IP addresses of
the hosts allowed to access the service. The default value is “*” which allows all
hosts to access the service. Limited wildcards are supported. Specifically, an address
of the form: 205.238.107.* allows execution from that TCP/IP subnet. The “*”
must occur only at the end of TCP/IP addresses. It must be immediately
followed/proceeded by a “.”.
Example:
205.238.107.*,128.110.163.210
