Telnet on the OnBoard
Telnet on the OnBoard
By default, Telnet is configured as follows:
•
Users cannot use Telnet to connect to the OnBoard or through the
OnBoard to connected devices.
•
The OnBoard uses Telnet to connect to devices on behalf of authorized
users.
The following table shows the tasks for changing the default
telnet
configuration with links to where the tasks are documented.
Configuring Telnet for Users
The OnBoard uses Telnet when connecting to service processors except when
connecting to IPMI service processors, when it uses
ipmitool
commands.
Telnet is used in all other cases because some service processors do not
support
SSH
.
The telnet service is not supported by any of the default security profiles and
by default,
telnetd
is turned off. The OnBoard-specific service processor
management commands cannot be passed as parameters to
telnet
on the
command line. Telnet can be enabled by an administrative user on the Web
Manager Config
→
Services page or by the root user, who can use normal
Linux commands to start
telnetd
on the command line.
Caution!
Because Telnet is not secure and not encrypted, its use by users for
directly connecting to devices or to the OnBoard is strongly discouraged.
See “Configuring the OnBoard’s Services” on page 229.
