Authentication Parameters
For an encrypted connection, the URI includes a set of authentication parameters. Enter the parameters
as key words or key/value pairs. You can enter authentication parameters for secure Telnet (telnets), or
for Telnet (telnet) as shown in the following syntax:
telnet://host:port #key[=value] [&key[=value] ...]
The first parameter must have a number sign (#) prefix. Additional parameters must have an ampersand
(&) prefix. The following parameters are supported.
thumbprint=value
Specifies a certificate thumbprint against which the peer certificate
thumbprint is compared. When you specify a thumbprint, certificate
verification is enabled.
peerName=value
Specifies the peer name that is used to validate the peer certificate. When
you specify a peer name, certificate verification is enabled.
verify
Forces certificate verification. The virtual machine will verify that the peer
certificate subject matches the specified peerName and that it was signed
by a certificate authority known to the ESXi host. Verification is enabled if
you specify a thumbprint or peerName
cipherList=value
Specifies a list of SSL ciphers. The ciphers are specified as a list separated
by colons, spaces, or commas.
Example: Establishing Serial Port Network Connections to a Client or Server
Simple Server
Connection
To connect to a virtual machine's serial port from a Linux or Windows
operating system if you do not use vSPC, configure the virtual machine with
a serial port connected as a server with a telnet://:12345 URI. To
access a virtual serial port from a client, use telnet
yourESXiServerIPAddress 12345.
Secure Server
Connection
To enforce an encrypted connection to the virtual machine's serial port from
a Linux operating system, you can configure Telnet to enforce encryption by
configuring the virtual machine with a serial port connected as a server with
a telnet://:12345#verify URI.
To access a virtual serial port from a client, use telnet-ssl
yourESXServerName 12345. This connection will fail if the Telnet program
you are using does not support SSL encryption.
