3Com MSR 50 Series Configuration Manual page 777

Installing and Configuring SCO OpenServer Server 777
determines which router and which terminal on the router a pseudo terminal
corresponds to. This guarantees terminal number fixing. For example, the above
sample entry shows that pseudo terminal ttyp30 on the Unix server corresponds to
the terminal connected to the asynchronous interface with a terminal number of 1
on router 10.110.96.44. The name of a pseudo terminal must be present in the
/dev directory and must start with tty. To configure pseudo terminal names not to
start with "tty", you must use a full path name starting with "/dev/".
accesstime 2 8:00-12:00 13:00-18:00" in the sample entry specifies that the
terminal can be connected to the Unix server during two periods only: 8:00 to
12:00 and 13:00 to 18:00. Up to four access periods can be defined for a
terminal. By default, no time restriction is imposed. Note that access periods are
synchronized with the system clock of the FEP. This parameter functions in
one-to-one mode only.
ttyp30 10.110.96.44 1 mac 02-f3-22-3e-2e-01
This sample entry specifies that the router with the IP address of 10.110.96.44 has
a MAC address of 02-f3-22-3e-2e-01, and that the router must send its MAC
address for authentication before it can perform normal operations. After this
command is used, MAC address binding must also be configured on the router.
To configure authentication and access periods at the same time, you need to
configure them in the same line and make sure the access period is configured
before the authentication. See the following example:
ttyp30 10.110.96.44 1 accesstime 1 8:00-18:00 mac 02-f3-22-3e-2e-01
ttyp30 10.110.96.44 1 <str> beijing-01 </str>
<str> beijing-01 </str>" indicates the character string that the router with the IP
address of 10.110.96.44 sends for authentication. The router needs to send its
authentication character string. If the authentication character string is consistent
with that in the configuration file, the authentication succeeds; otherwise, the
authentication fails. After this command is used, character string binding must
also be configured on the router.
To configure authentication and access periods at the same time, you need to
configure them in the same line and make sure the access period is configured
before the authentication. See the following example:
ttyp30 10.110.96.44 1 accesstime 1 8:00-18:00 <str> beijing-01 </str>
exit 1
If "exit 1" is configured in the configuration file, terminating the connection using
the hotkey or the reset rta connection command will terminate the ttyd
program. When you re-log into the FEP, the login interface displays on the
terminal. If authentication is configured on the FEP, you need to enter the
password before performing any operation on the FEP. If neither exit 1 nor exit 0 is
configured, terminating the connection using the hotkey or the reset rta
connection command will not terminate the ttyd program. In this case, when you
re-log into the FEP, the login interface does not display on the terminal, and you
don't need to pass the authentication for further operations on the FEP.
