DESCRIPTION

14       The virtual console daemon, cvcd, is a server process that supports the
15       network console provided on some platforms.  The  cvcd  daemon  accepts
16       network  console  connections  from a remote host (only one host at any
17       given time). Console input is read from this connection  and  forwarded
18       to cvc(7D) by way of cvcredir(7D).
19
20
21       Similarly,  console  output  is  read  from  cvcredir(7D) and forwarded
22       across the network console connection. If cvcd dies, console traffic is
23       automatically rerouted through an internal hardware interface.
24
25
26       The  cvcd  daemon normally starts at system boot time. Each domain sup‐
27       ports only one cvcd process at a time.
28
29       Caution -
30
31         On Sun Enterprise 10000  domains,  cvcd  uses  a  configuration  file
32         (/etc/ssphostname)  to determine the name of the host from which net‐
33         work console connections are allowed. If the remote console  host  is
34         renamed, you must edit the configuration file to reflect that change.
35
36
37       The  cvcd  daemon  supports per-socket IP Security Architecture (IPsec)
38       through the options described below. See ipsec(7P).
39

OPTIONS

41       The cvcd daemon supports the options listed below.
42
43       -a auth        Controls the IPsec Authentication Header (AH) algorithm.
44                      auth can be one of none, md5, or sha1.
45
46
47       -e encr        Controls  the IPsec Encapsulating Security Payload (ESP)
48                      encryption algorithm. encr can be one of none,  des,  or
49                      3des.
50
51
52       -u esp_auth    Controls  the IPsec Encapsulating Security Payload (ESP)
53                      authentication algorithm. esp_auth can be one  of  none,
54                      md5, or sha1.

OPERANDS

58       The following operands are supported:
59
60       platform_name    The  official  Sun platform name used in packaging and
61                        code. For example, for Sun Fire 15K servers, the plat‐
62                        form_name would be SUNW,Sun-Fire-15000.

EXAMPLES

66       Example 1 Setting an IPSec Option
67
68
69       The  command  below  sets  the value of the IPsec Authentication Header
70       algorithm to md5. As a result of this command, cvcd will use the  HMAC-
71       MD5 authentication algorithm.

74         # svccfg -s svc:/system/cvc setprop cvc/ah_auth = "md5"
75         # svccfg -s svc:/system/cvc setprop cvc/esp_encr = "none"
76         # svccfg -s svc:/system/cvc setprop cvc/esp_auth = "none"
