NAME

cvcd- virtual console daemon

DESCRIPTION

cvcd is a server process that resides on an Enterprise 10000 domain. cvcd accepts connections from netcon_server on a System Service Processor (SSP) to create a Network Console Window on that SSP. The Network Console Window is able to read data from, and possibly send data to, the domain. This process takes place by way of the SSP netcon command. See netcon_server(1M) and netcon(1M) in the Sun Enterprise 10000 SSP Reference Manual.

When you execute the netcon command in an SSP Window, netcon_server connects with the cvcd daemon running on the domain specified in the SSP's SUNW_HOSTNAME environment variable and the window becomes a Host Console Window.

The console session ends when you exit the session, netcon_server terminates, or a network failure occurs. If cvcd dies, netcon automatically switches to the alternate communications path to send and receive console data. The alternate communications path is implemented as JTAG and communicates through the control board.

cvcd is normally started up at system boot time. Each domain supports only one cvcd process at a time.

Caution:

cvcd uses the file /etc/ssphostname, one copy of which resides on each domain to determine the name of the host to which connections are allowed. If the SSP has been renamed, all /etc/ssphostname files must be edited to reflect that change.
