cards. By reducing the number of Channel Extender ports, the maximum number of available connections for 10/100 network access is reduced by four sessions for each Terminal Card installed. Illustrations showing a mixture of Channel Extender cards and Terminal Cards are found on pages 11 and 16 of this Guide.
An optional MODEM connection is also available, however its connections are not 'secure' and its use is not recommended except in those instances when security will not be compromised by
2.4Security Passwords
The System Administrator may define up to 200 user profiles. Each user is assigned a unique password by the system administrator. The system forces the user to change the password the first time the user attempts to connect to any servers. After the users have changed their passwords, the system will not prompt for a change. The users change their passwords at whatever interval they feel is necessary.
The operating system is subject to Linux security constraints, including sysadmin and root level security. Users cannot access the sysadmin layer or the root layer of the system.
2.5Interface
Interfaces to the DEVICE and TERMINAL cards are all
Each DEVICE port and TERMINAL has settings for baud rate, stop bits, parity, number of data bits, flow control, and port type (i.e., DTE or DCE). The TERM port (for your Console) on the NETWORK / CONTROL card has a fixed data format of 9600 / 8/ N / 1, and DCE.
The NETWORK / CONTROL card connects over a network using TCP/IP on 10- or
The optional MODEM card connects directly to a conventional modular phone jack (RJ11) to interface with a telephone network. The sys admin may designate a modem initialization string, or may use the default modem initialization string, which allows
Note: For 'secure' installations, the Modem should not be used. Modem access is not encrypted and/or secure and could allow unauthorized access to system information. However, if modem access is limited to internal administrative access, the modem may provide an additional means of system access in the event your network is down.
