NOTE: When accessing the console server via the web UI, do not disable additional dialogs if prompted by your
browser. Disabling dialogs will disable some functionality of the web UI.
1.1.3 IPv4 and IPv6 support
The console server supports dual stack IPv4 and IPv6 protocols. The administrator can use the web UI 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 console server:
•
DHCP
•
Dial-in and dial-out sessions (PPP links)
•
DSView software integration
•
eth0 and eth1 Ethernet interfaces
•
Firewall (IP tables)
•
HTTP/HTTPs
•
Linux kernel
•
Remote authentication: Radius, , LDAP and Kerberos servers
•
SNMP
•
SSH and Telnet access
•
Syslog server
NOTE: IPSec is not supported with IPv6.
1.1.4 Flexible users and groups
An account can 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 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 or individual users. For more information, see
Users accounts and user groups
on page 51.
1.1.5 Security
Security profiles determine which network services are enabled on the console server. Administrators can either allow all
users to access enabled ports or allow the configuration of group and user authorizations to restrict access. You can also
select a security profile, which defines which services (FTP, TFTP, 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. For
more information, see
Security
on page 18.
1.1.6 Authentication
Authentication can be performed locally, with One Time Passwords (OTP), a remote Kerberos, LDAP, RADIUS,
authentication server or a DSView server. The console server also supports remote group authorizations for the LDAP,
RADIUS and 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 UI. For more information, see
Authentication
on page 49.
1.1.7 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.
For more information, see
IPSec(VPN)
on page 26.
