6 Cyclades ACS 6000 Advanced Console Server Installation/Administration/User Guide
More than one administrator (root or admin or a user in the administrator group) can log into the
console server and have an active CLI or Web Manager session. All sessions receive a warning
message when the configuration is changed by another administrator: “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.
NOTE: If cron jobs are run by automated scripts, a root or admin user login can cause the cron jobs to fail.
IPv4 and IPv6 Support
The ACS 6000 console server supports dual stack IPv4 and IPv6 protocols. The administrator can
use either the Web Manager or the CLI to configure support for IPv4 addresses only or for both
IPv4 and IPv6 addresses. The following list describes the support provided in the console server for
IPv6 addresses:
• Linux kernel
• Both the eth0 and eth1 Ethernet interfaces can be configured for IPv6
• DHCP
• Access to the console server or to target devices with SSH or Telnet
• Syslog server
• Dial-in sessions (PPP links)
• Firewall (IP tables)
• DSView software integration
Remote authentication, IPSec and SNMP are not supported with IPv6 but are supported with IPv4.
Users, Groups and Authorizations
A user account must be defined for each user on the 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.
User account types
The following gives additional details about the local user account types supported on the ACS
6000 console server:
• admin - Performs the initial network configuration. The factory default password for admin is
avocent. The admin user is a member of the admin group. The admin user can configure the
console server and ports. Administrators also configure user and group authorizations.
• root - Has the same permissions as the admin user. The factory default password for root is
linux. In the ACS 6000 console server, the root user is a member of the admin group.
CAUTION: Change the default passwords for root and admin before you put the console server into operation.
