vntsd(1M) System Administration Commands vntsd(1M)
NAME
vntsd - virtual network terminal server daemon for Logical Domains
SYNOPSIS
/usr/lib/ldoms/vntsd
DESCRIPTION
The vntsd daemon is a server that supports connections to the Logical Domains (LDoms) console by using telnet(1). When a telnet session
starts, vntsd sends telnet options to the client indicating a willingness to remotely echo characters and to suppress go ahead.
Consoles are organized into groups by the LDoms Manager. Each console group is assigned a unique group name and TCP port number. vntsd uses
the group's port number to export access to the consoles within that group. To establish a connection with a console or console group, a
user starts a telnet(1) session with the corresponding group's port number. Depending on the number of consoles within that group, vntsd
does one of two things:
o If there is only one console in the group, vntsd connects a session to that LDoms console.
o If there are multiple consoles in the group, vntsd prompts the user to select the console to which they would like to connect,
as shown in "Multiple-Console Options," below.
For each console, vntsd provides write access only to the first user connecting to the console. Subsequent users connecting to the console
are allowed only to read from the console and wait for write access. When the first user disconnects, write privileges are transferred to
the next user waiting in the queue. If a user who does not have write privileges attempts to write to a console, the vntsd displays the
following message:
You do not have write access
A user who has no write access can acquire write access forcibly by using the ~w special console command, described in "Special Console
Commands," below.
vntsd can be invoked only with superuser privileges or by someone in the Primary Administrator role.
OPTIONS
The options for vntsd are divided into multiple-console options and console commands.
Multiple-Console Options
The options listed below are supported when there are multiple LDoms consoles in a group. The syntax for the use of these options is:
<hostname>-vnts-<group-name>: <option>
For example:
myhost-vnts-salesgroup: h
The h option invokes help, as described below.
h
Display the following help text:
h -- this help
l -- list of consoles
q -- quit
c{id}, n{name} -- connect to console of domain {id} or domain name
l
List all consoles in the group. For example:
DOMAIN ID DOMAIN NAME DOMAIN STATE
0 ldg1 online
1 ldg2 connected
... ... ...
The two domain states and their meanings are:
online
No one is connected to the console.
connected
At least one user is already connected to the console.
q
Disconnect from vntsd.
c{id}, n{name}
Connect to specified console. Upon connection, the following message is displayed:
Connecting to console <domain-name> in group <group-name>
Press ~? for control options ....
Special Console Commands
A tilde (~) appearing as the first character of a line is an escape signal that directs vntsd to perform a special console command. The
tilde-tilde (~~) sequence outputs a tilde. In conjunction with the initial tilde, vntsd accepts the following special console commands:
~.
Disconnect from the console or console group.
~w
Force write access to the console.
~p
Disconnect from this console, and connect to the console that precedes this console in the list of consoles.
~n
Disconnect from this console, and connect to the console that follows this console in the list of consoles.
~#
Send break.
~?
Display vntsd help, as follows:
~# - Send break
~. - Exit from this console
~w - Force write access
~n - Console next
~p - Console previous
~? - Help
FILES
/usr/lib/ldoms/vntsd

NOTES
The vntsd is managed by the service management facility, smf(5), under the service identifier:
svc:/ldoms/vntsd
You can change the following properties using the svccfg(1M) command:
vntsd/vcc_device
Set an instance of the virtual console concentrator (vcc) driver to which vntsd is connected.
vntsd/listen_addr
Set the IP address to which vntsd listens, using the following syntax:
vntsd/listen_addr:"xxx.xxx.xxx.xxx"
...where xxx.xxx.xxx.xxx is a valid IP address. The default value of this property is to listen on IP address 127.0.0.1. Users can con-
nect to a guest console over a network if the value is set to the IP address of the control domain.
Note -
Enabling network access to a console has security implications. Any user can connect to a console and for this reason it is disabled
by default.
vntsd/timeout_minutes
Set timeout in minutes. vntsd will timeout (close) telnet connection if there is no activity (input or output) on the console. The
default value is 0, which disables timeout.
vntsd/authorization
Enable the authorization checking of users and roles for the domain console or consoles that are being accessed. The default value of
this property is false to maintain backward compatibility. To enable authorization checking, use the svccfg(1M) command to set the
property value to true. While this option is enabled, vntsd listens and accepts connections on localhost. If the listen_addr property
specifies an alternate IP address when this option is enabled, vntsd ignores the alternate IP address and continues to listen on local-
host. Connections that are initiated from other hosts will also fail. Authorizations are available to access all consoles or console
groups, or to access specific consoles or console groups. When the vntsd service is enabled, the following authorization is added to
the authorization description database, auth_attr(4):
solaris.vntsd.consoles:::Access All LDoms Guest Consoles::
Add any fine-grained authorizations based on the name of the console group. For example, if the name of the console group to be autho-
rized is ldg1, add the following entry to the auth_attr(4) file:
solaris.vntsd.console-ldg1:::Access Specific LDoms Guest Console::
By default, the authorization to access all consoles is assigned to the root user or role. The Primary Administrator (superuser) can
use the usermod(1M) command to assign the required authorization or authorizations to other users or roles.
The following example gives user user1 the authorization to access all domain consoles:
# usermod -A "solaris.vntsd.consoles" user1
The following example gives user user1 the authorization to access the console group named ldg1:
# usermod -A "solaris.vntsd.console-ldg1" user1
