Spider™ and SpiderDuo® KVM-over-IP Device User Guide 82
RADIUS
When RADIUS is selected, the Spider device communicates with a RADIUS server for user
authentication. To access a Spider device set up for RADIUS, log in with a name and password.
The Spider device contacts the RADIUS server for authentication and, if approved, the Spider
device uses the locally stored user profile. If there is no such profile, access via RADIUS will be
refused.

a. Click Save to save settings.

Bind Name The name for a non-anonymous bind to an LDAP server. This item has the

Confirm Password
Password for a non-anonymous bind. This entry is optional. Acceptable
characters are a-z, A-Z, and 0-9.
The maximum length is 127 characters.
Field Description
Server Enter the name or IP address of the RADIUS server, reachable over the
network by the Spider device, containing the user database. Configure a
DNS server if a name rather than an address is used.
Shared Secret A shared secret is a text string that serves as a password between the
RADIUS client and RADIUS server. In this case the Spider device acts as a
RADIUS client. A shared secret is used to verify that RADIUS messages are
sent by a RADIUS-enabled device that is configured with the same shared
secret and to verify that the RADIUS message has not been modified in
transit (message integrity).
Enter a maximum of 128 alphanumeric characters and symbols such as an
exclamation point (“!”) or an asterisk (“*”).
Authentication Port The port the RADIUS server listens for authentication requests. The default
value is 1812.
Accounting Port The port the RADIUS server listens for accounting requests. The default
value is 1813.
Timeout Sets the request time-to-live in seconds. The time-to-live is the time to wait
for the completion of the authentication request. If the request job is not
completed within this interval of time it is cancelled. The default value is 1
second.
Retries Sets the number of retries if a request could not be completed. The default
value is 3 times.
