Console Server Features
3.5 Login Banner Pages
Banner pages allow you to display text messages to users before and after authentication. Banner text
information is taken from two files named prelogin.txt and postlogin.txt stored in the /ram or /flash
directory on the SCS. The SCS does not store or display files stored in the /ram directory after rebooting.
To implement login and logout banner text:
Create text files with the desired text name prelogin.txt and/or postlogin.txt.
1
2 FTP to the IP address of the SCS.
Log in with the username root and enter the privileged password (system by default.)
3
4 Change directories to /flash or /ram.
5 "Put" the text files into the desired directory.
Reboot the SCS.
6
Subsequent users logging in or out of the SCS see the text in the prelogin.txt and postlogin.txt files,
respectively. The standard company/product/version banner displays if either of these two files is not
present in the SCS.

3.6 Managing the Attached Devices

You can manage the SCS's connected serial devices over a network connection or through a modem
connection. Both of these methods ensure that the SCS and its attached serial devices are always accessible
and manageable, even in critical situations.

3.6.1 In-Band Management

The SCS provides TCP/IP socket connections to its serial ports. A TCP session to port 30xx, where xx is the
serial port number, will form a raw TCP/IP connection to that serial port. A connection to port 20xx provides
Telnet IAC interpretation.

% telnet 192.0.1.66 2002
To connect to a specific SCS port using SSH, use socket number 22xx, where xx is the port number. The
syntax for an SSH connection depends on your client software. SSH is discussed in SSH Sessions on page
6-10.
