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
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.
55
56
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.

64
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.
