Example: Establishing Serial Port Network Connections to a Client or Server
Without Authentication Parameters
If you do not use vSPC and you configure your virtual machine with a serial port connected as a server
with a telnet://:12345 URI, you can connect to your virtual machine's serial port from your Linux or
Windows operating system.
telnet yourESXiServerIPAddress 12345
Similarly, if you run the Telnet Server on your Linux system on port 23 (telnet://yourLinuxBox:23),
you configure the virtual machine as a client URI.
telnet://yourLinuxBox:23
The virtual machine initiates the connection to your Linux system on port 23.
Authentication Parameters for Virtual Serial Port Network
Connections
When you establish serial port connections over the network, you can use authentication parameters to
secure the network. These parameters can support an encrypted connection with a remote system using
SSL over Telnet or Telnets, or an encrypted connection with a concentrator using SSL over Telnet or
Telnets.
URI Forms
If you do not use virtual serial port network connection (vSPC) and you configure your virtual machine
with a serial port connected as a server with a telnet://:12345 URI, you can connect to your virtual
machine's serial port from your Linux or Windows operating system. You use one of the following formats:
n
Telnet over TCP.
telnet://host:port
The virtual machine and remote system can negotiate and use SSL if the remote system supports the
Telnet authentication option. If not, the connection uses unencrypted text (plain text).
n
Telnets over SSL over TCP.
telnets://host:port
SSL negotiation begins immediately, and you cannot use the Telnet authentication option.
