Build options

This setting is available only when the build option CONSOLE_SYSLOGS is enabled.

Notes

The encrypted syslog server name must exactly match the name in the TLS certificate presented by the server.

It make take a short time for the connection to the encrypted syslog server to be established. During this time, any log messages will be lost. You may therefore wish to use the sync command to wait for the connection attempt to complete. For example:

  #!ipxe
  
  set syslogs syslog.example.com
  sync
  chain ${filename}  # Continue with boot

There is no way to detect whether or not the connection to the encrypted syslog server was successful.

Using an encrypted syslog server is more secure than using a standard unencrypted syslog server, but may be less reliable since there are several circumstances in which messages may be lost.
