cvcd - virtual console daemon 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 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. 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) authentication 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 packaging 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 ATTRIBUTES

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 svc- cfg(1M). The service's status can be queried using the svcs(1) command. SunOS 5.11 9 Mar 2006 cvcd(1M)
