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 all other types of devices and service processors do support Telnet, but some 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 device management commands cannot be passed as parameters to telnet on the command line. telnetd can be enabled by an administrative user on the Web Manager Config Æ 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, allowing its use by users for directly connecting to devices or to the OnBoard is strongly discouraged.
