cvcd
cvcd(1M) System Administration Commands cvcd(1M)NAME
cvcd - virtual console daemon
SYNOPSIS
/platform/platform_name/cvcd
DESCRIPTION
The virtual console daemon, cvcd, is a server process that supports the network console provided on some platforms. The cvcd daemon accepts
network console connections from a remote host (only one host at any given time). Console input is read from this connection and forwarded
to cvc(7D) by way of cvcredir(7D).
Similarly, console output is read from cvcredir(7D) and forwarded across the network console connection. If cvcd dies, console traffic is
automatically rerouted through an internal hardware interface.
The cvcd daemon normally starts at system boot time. Each domain supports only one cvcd process at a time.
Caution: On Sun Enterprise 10000 domains, cvcd uses a configuration file (/etc/ssphostname) to determine the name of the host from
which network console connections are allowed. If the remote console host is renamed, you must edit the configuration file
to reflect that change.
OPERANDS
The following operands are supported:
platform_name The official Sun platform name used in packaging and code. For example, for Sun Fire 15K servers, the platform_name
would be SUNW,Sun-Fire-15000.
