SYNOPSIS
/platform/platform_name/cvcd [-a auth] [-e encr] [-u esp_auth]
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 sup‐
ports 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 configura‐
tion file to reflect that change.
The cvcd daemon supports per-socket IP Security Architecture (IPsec)
through the options described below. See ipsec(7P).
OPTIONS
The cvcd daemon supports the options listed below.
-a auth
Controls the IPsec Authentication Header (AH) algorithm. auth can
be one of none, md5, or sha1.
-e encr
Controls the IPsec Encapsulating Security Payload (ESP) encryption
algorithm. encr can be one of none, des, or 3des.
-u esp_auth
Controls the IPsec Encapsulating Security Payload (ESP) authentica‐
tion algorithm. esp_auth can be one of none, md5, or sha1.
OPERANDS
The following operands are supported:
platform_name The official Sun platform name used in packag‐
ing and code. For example, for Sun Fire 15K
servers, the platform_name would be SUNW,Sun-
Fire-15000.
EXAMPLES
Example 1: Setting an IPSec Option
The command below sets the value of the IPsec Authentication Header
algorithm to md5. As a result of this command, cvcd will use the HMAC-
MD5 authentication algorithm.
# svccfg -s svc:/system/cvc setprop cvc/ah_auth = "md5"
# svccfg -s svc:/system/cvc setprop cvc/esp_encr = "none"
# svccfg -s svc:/system/cvc setprop cvc/esp_auth = "none"
# svcadm refresh svc:/system/cvc

NOTES
The cvcd service is managed by the service management facility, smf(5),
under the fault management resource identifier (FMRI):
svc:/system/cvc
Administrative actions on this service, such as enabling, disabling, or
requesting restart, can be performed using svcadm(1M) or svccfg(1M).
The service's status can be queried using the svcs(1) command.
