System Administration Commands                           cvcd(1M)



NAME
     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 for-
     warded  across the network console connection. If cvcd dies,
     console traffic is automatically rerouted through an  inter-
     nal 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 confi-
       guration 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.

System Administration Commands                           cvcd(1M)



     -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

NOTES
     The cvcd service is managed by the service management facil-
     ity,  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.
