cvc - virtual console driver DESCRIPTION
The cvc virtual console driver is a STREAMS-based pseudo driver that supports the network console. The cvc driver interfaces with con- sole(7D). Logically, the cvc driver sits below the console driver. It redirects console output to the cvcredir(7D) driver if a network console con- nection is active. If a network console connection is not active, it redirects console output to an internal hardware interface. The cvc driver receives console input from cvcredir and internal hardware and passes it to the process associated with /dev/console. NOTES
The cvc facility supersedes the SunOS wscons(7D) facility, which should not be used in conjunction with cvc. The wscons driver is use- ful for systems with directly attached consoles (frame buffers and keyboards), but is not useful with platforms using cvc, which have no local keyboard or frame buffer.

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. ATTRIBUTES

The cvcd service is managed by the service management facility, smf(5), under the service identifier: svc:/system/cvc Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser- vice's status can be queried using the svcs(1) command. SunOS 5.10 11 Aug 2004 cvcd(1M)
