Introduction  
1
The Avocent ACS v6000 virtual advanced console server serves as a single point for access and  
administration of connected virtual machines. Virtual console servers support secure remote data  
center management and out-of-band management of IT assets from any location worldwide.  
Multiple administrators can be logged into the virtual console server at the same time and can  
use the web manager, the Command Line Interface (CLI) or DSView™ 3 management software  
(version 3.6.0.152 and greater) to access and configure the virtual console server.  
Features and Benefits  
Access options  
Secure access is available through the following options:  
LAN IP network connection.  
Target device connection. An authorized user can make a Telnet, SSH v1 or SSH v2  
connection to a target device. For Telnet or SSH to be used for target device connections, the  
Telnet or SSH service must be configured in the Security Profile that is in effect.  
ACS v6000 virtual console server console connection. An administrator can log in using the  
Console via vSphere application and can use the CLI utility. The CLI utility prompt (--|-  
cli>) displays at login.  
More than one administrator can log into the virtual console server and have an active CLI or  
web manager session. All sessions receive the following warning message when the configuration  
is changed by another administrator or by the system: The appliance configuration has been  
altered from outside of your session. Upon receipt of this message, each administrator needs to  
verify that changes made during the session were saved.

Web Manager  
Users and administrators can perform most tasks through the web manager (accessed with HTTP  
®
®
or HTTPS). The web manager runs in the Microsoft Internet Explorer 6.0 and 7.0 internet  
®
®
browser, and the Mozilla Firefox 2 and 3 internet browser on any supported computer that  
has network access to the virtual console server.  
An administrator can use the web manager to create user accounts, authorize groups and  
configure security and ports. Authorized users can access connected devices through the web  
manager to troubleshoot, maintain, reboot connected devices and change their password. For  
more information on the web manager, see Accessing a Virtual Console Server via the Web  
IPv4 and IPv6 support  
The virtual console server supports dual stack IPv4 and IPv6 protocols. The administrator can  
use the web manager or CLI to configure support for IPv4 addresses only or for both IPv4 and  
IPv6 addresses. The following list describes the IPv6 support provided in the virtual console  
server:  
DHCP  
DSView software integration  
eth0 Ethernet interface  
Firewall (IP tables)  
HTTP/HTTPs  
Linux kernel  
Remote authentication: Radius, Tacacs+, LDAP and Kerberos servers  
SNMP  
SSH and Telnet access  
Syslog server  
NOTE: Remote authentication NFS, NIS and IPSec are not supported with IPv6.  
Flexible users and groups  
An account can be defined for each user on the virtual console server or on an authentication  
server. The admin and root users have accounts by default, and either can add and configure  
other user accounts. Access to ports can be optionally restricted based on authorizations an

administrator can assign to custom user groups. For more information, see Users Accounts and  
Security  
Security profiles determine which network services are enabled on the virtual console server.  
Administrators can either allow all users to access enabled ports or allow the configuration of  
group authorizations to restrict access. You can also select a security profile, which defines  
which services (FTP, ICMP, IPSec and Telnet) are enabled and SSH and HTTP/HTTPS access.  
The administrator can select either a preconfigured security profile or create a custom profile.  
Authentication  
Authentication can be performed locally, with One Time Passwords (OTP), a remote Kerberos,  
LDAP, NIS, RADIUS, TACACS+ authentication server or a DSView 3 server. The virtual  
console server also supports remote group authorizations for the LDAP, RADIUS and  
TACACS+ authentication methods. Fallback mechanisms are also available.  
Any authentication method configured for the console server or the ports is used for  
authentication of any user who attempts to log in through Telnet, SSH or the web manager.  
VPN based on IPSec with NAT traversal  
If IPSec is enabled in the selected security profile, an administrator can use the VPN feature to  
enable secure connections. IPSec encryption with optional NAT traversal (which is configured  
by default) creates a secure tunnel for dedicated communications between the virtual console  
server and other computers that have IPSec installed. ESP and AH authentication protocols,  
RSA Public Keys and Shared Secret are supported.  
Packet filtering  
An administrator can configure a virtual console server to filter packets like a firewall. Packet  
filtering is controlled by chains, which are named profiles with user-defined rules. The virtual  
console server filter table contains a number of built-in chains that can be modified but not  
deleted. An administrator can also create and configure new chains.  
SNMP  
If SNMP is enabled in the selected security profile, an administrator can configure the Simple  
Network Management Protocol (SNMP) agent on the virtual console server to send  
notifications or traps to an SNMP management application.  
The virtual console server SNMP agent supports SNMP v1/v2 and v3, MIB-II and Enterprise  
MIB.

Data logging, notifications, alarms and data buffering  
An administrator can set up data logging, notifications and alarms to alert administrators of  
problems with email, SMS, SNMP trap or DSView 3 software notifications. An administrator  
can also store buffered data locally, remotely or with DSView 3 software. Messages about the  
virtual console server and connected servers or devices can also be sent to syslog servers.  
Auto discovery  
An administrator can enable auto discovery to find the hostname of a target connected to a  
serial port. Auto discovery’s default probe and answer strings have a broad range. An  
administrator can configure site-specific probe and answer strings. Auto discovery can also be  
configured through DSView 3 software.

IPSec(VPN)  
Virtual Private Network (VPN) enables a secure communication between the virtual console  
server and a remote network by utilizing a gateway and creating a secured connection between  
the virtual console server and the gateway. The IPSec protocol is used to construct the secure  
tunnel and provides encryption and authentication services at the IP level of the protocol stack.  
NOTE: IPSec(VPN) is not supported with IPv6.  
When Network - IPSec(VPN) is selected, the IPSec(VPN) screen is displayed.

The remote gateway is referred to as the remote or right host and the virtual console server is  
referred to as the local or left host. If left and right are not directly connected, then you must  
also specify a NextHop IP address.  
The next hop for the remote or right host is the IP address of the router to which the remote  
host or gateway running IPSec sends packets when delivering them to the left host. The next  
hop for the left host is the IP address of the router to which the virtual console server sends  
packets to for delivery to the right host.  
A Fully Qualified Domain Name should be indicated in the ID fields for both the Local (Left)  
host and the Remote (Right) host where the IPSec negotiation takes place.

CAS Profile  
An administrator can configure settings for auto discovery and for auto answer features.  
Auto discovery  
The auto discovery feature will discover the target name of the server connected to the serial  
port. This name will be used as the alias of the serial port.  
When auto discovery is active for a certain serial device, upon target connection (DCD ON  
event), the appliance will send probe strings and start analyzing target device answers using  
regular expressions. There will be predefined probe and match strings as well as customer-  
defined ones.  
For each probe string sent, all regular expressions defined by the match strings will be tested.  
After the last cycle, the sequence restarts. This procedure will run for a certain period (given by  
the auto discovery time-out parameter) or until the target is successfully detected. If auto  
discovery fails, the target name will be reset to the configured target name or to the  
corresponding unique default target name.  
NOTE: The configured target name will be used only after the auto discovery process fails.  
NOTE: The auto discovery process starts when there is variation in the DCD signal from OFF to ON  
(disconnect/connect the target's cable, turn off/on the target) and when the configuration of the serial port goes  
from disabled to enabled and there is a target connected in the port.  
The probe strings will be used to stimulate the server (such as “\n”: a single newline).  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Chapter 3: Accessing a Virtual Console Server via the Web Manager 33  
The match strings are regular expressions where “%H” is a placeholder for the target name you  
want to detect, such as:  
“ \\(.*\\)(%H)\\(.*\\)” or just “xxx%Hyyy”.  
The first one will extract target name from things such as:  
nanana(myTarget): à results: myTarget  
jhdsgjhas(tg2)kjafja à results: tg2  
But would match for:  
hsagdfjhagfxxxTARGETyyyyyy à resulting: TARGET

Authentication  
Authentication can be performed locally, with OTP, or on a remote Kerberos, LDAP, NIS,  
Radius or TACACS+ authentication server. If the virtual console server is managed by a  
DSView 3 server, DSView authentication is also supported. The virtual console server also  
supports remote group authorizations for LDAP, Radius and TACACS+ authentication  
methods.  
Fallback mechanisms of the following types are available:  
Local authentication can be tried first, followed by remote, if the local authentication fails  
(Local/Remote_Method).  
-or-  
Remote authentication may be tried first, followed by local (Remote_Method/Local).  
-or-  
Local authentication may be tried only if a remote authentication server is down (Remote_  
Method_Down_Local).  
An administrator can configure authentication using the CLI utility or the web manager. The  
default authentication method for the virtual console server and the serial ports is Local. Any

authentication method that is configured for the virtual console server or the ports is used for  
authentication of any user who attempts to log in through Telnet, SSH or the web manager.  
Appliance authentication  
The virtual console server authenticates for the virtual console server and the ports, either in  
groups or individually.  
NOTE: It is advised when using group authorization that you use the same authorization for both the virtual console  
server and all serial ports, or use Single Sign-on Authentication to facilitate group authorization.  
When Single Sign-on Authentication is disabled, the virtual console server uses the individual  
port configurations. Users must use their password each time they access an individual port. If  
enabled, Single Sign-on Authentication will use the authentication server you choose from the  
pull-down menu for all ports and no further authentication will be needed when accessing the  
port after that.  
NOTE: Selecting unconfigured from the pull-down menu will allow the ports to continue to use individual  
authentication servers, and will require your password the first time you access any port. After that, the port will not  
require password authentication if Single Sign-on Authentication is enabled.  
To set authentication for the console server:  
1. Click Authentication - Appliance Authentication.  
2. Select the desired authentication server from the Authentication Type drop-down menu.  
3. Select Enable single sign-on to enable single sign-on authentication, and select the desired  
authentication server from the Authentication Type drop-down menu.  
4. Click Save.  
Authentication servers  
When using an authentication server, you must configure its IP address and in most cases other  
parameters before it can be used. The following authentication servers require configuration:  
RADIUS, TACACS+, LDAP(S)|AD, Kerberos, NIS and DSView 3 servers.  
To configure a RADIUS authentication server:  
1. Select Authentication - Authentication Servers - RADIUS.

Users Accounts and User Groups  
Access to ports can be optionally restricted, based on authorizations that an administrator can  
assign to custom user groups. The virtual console server has two default users (admin and root)  
and four pre-defined user groups: admin, appliance-admin, shell-login-profile and user.  
A user account must be defined for each user on the virtual console server or on an  
authentication server. The admin and root users have accounts by default, and either  
administrator can add and configure other user accounts. Each local user account is assigned to  
one or more of the user groups.

Chapter 3: Accessing a Virtual Console Server via the Web Manager 39  
Local accounts  
The admin and root are equivalent users but named differently to address users familiar with  
either Avocent or Cyclades™ appliances. Regular users can be granted permissions by  
administrators at any time. The virtual console server has three user account types:  
admin: Performs the initial network configuration. The factory default password for admin  
is avocent. The admin user is a member of the admin group and can configure the virtual  
console server and ports as well as user and group authorizations.  
root: Has the same permissions as the admin user. The factory default password for root is  
linux. In the virtual console server, the root user is a member of the admin group and shell-  
login-profile groups. When a root user logs in via SSH or telnet, the session is pre-defined  
by the login profile to go directly to shell. The login profile can be customized so that it  
does not go directly to shell.  
Administrator-added regular users: Have limited access to the web manager features based  
on the group(s) to which they are assigned. Users can change their own passwords. By  
default, all users have access to all enabled ports.  
To add new users:  
1. Click Users - Local Accounts - User Names. The User Names screen is displayed with a list  
of all users.  
2. Click Add. The Local User Information screen is displayed.  
3. Enter the new username and enter a password, then confirm the password.  
4. Select or deselect User must change password at the next login checkbox.  
5. If you wish to add the user to an available user group, select the user group name in the  
box on the left and click Add (user is the default group). You can remove a user group from  
the box at right by selecting it and clicking Remove.  
6. Enter the desired parameters for Password Expiration.  
Min Days: Enter the minimum number of days allowed between password changes.  
Password changes attempted sooner will be rejected. If not specified, -1 is the default  
which disables the restriction.  
Max Days: Enter the maximum number of days a password is valid. After this period, a  
password change will be forced. If not specified, -1 is the default which disables the  
restriction.

5. Click Save.  
User groups  
User groups are given access and authorizations either by default or as assigned by an  
administrator. Administrators can alter the permissions and access rights of users belonging to  
the appliance-admin or user groups or create additional groups with custom permissions and  
access rights. Administrators can add, delete or modify permissions and access rights for users  
from any group at any time.  
If an administrator configures the virtual console server to restrict user access to ports, the  
administrator can assign users to groups that are authorized for port access. The administrator  
can also authorize groups for data buffer management.  
This document and the software refer to users whose accounts are configured on remote  
authentication servers as remote users. Remote users do not need local accounts.  
Radius, TACACS+ and LDAP authentication services allow group configuration. If a remote  
user is configured as a member of a remote group, the authentication server provides the group  
name to the virtual console server when it authenticates the user. A local group by the same  
name must also be configured on the virtual console server. If an authentication server  
authenticates a remote user but does not return a group, then the remote user is, by default,  
assigned to the user group.  
admin group  
Members of the admin group have full administrative privileges that cannot be changed, the  
same access and configuration authorizations as the default admin user. Administrators can

To configure a group in a TACACS+ authentication server:  
1. On the server, add raccess service to the user configuration.  
2. Define which group(s) the user belongs to in the raccess service following this syntax:  
group_name = <Group1>[,<Group2,...,GroupN>];  
For example:  
In the virtual console server, configure a new authorization group TACACS_1 , and  
configure the access rights for this group. In the TACACS+ server, configure the user  
regina with the following attribute:  
raccess = group_name=TACACS_1  
Then, configure the user special with the following attribute:  
raccess = group_name=admin  
During the authentication phase, the virtual console server will receive the attribute  
raccess from the TACACS+ server. The user regina belongs to the authorization group  
TACACS_1 and the user special belongs to the authorization group admin.  
To configure a group in a RADIUS authentication server:  
Define which group(s) the user belongs to in the attribute FRAMED_FILTER_ID with the  
following syntax:  
[:group_name=]<acs6000_group1>[,<acs6000_group2>];  
NOTE: The group names should be separated by a comma and end with a semi-colon.  
NOTE: The virtual console server accepts multiple FRAMED_FILTER_ID attributes.  
For example:  
In the virtual console server, configure new authorization groups RADIUS_1 and RADIUS_2,  
and configure the access rights for these groups. In the Radius server, configure the user regina  
with the following attribute:  
FramedFilterID : FramedFilterID = group_name=RADIUS_1,RADIUS_2;  
-or-  
FramedFilterID = RADIUS_1,RADIUS_2;  
-or-  
FramedFilterID = RADIUS_1;
