Basic Configuration

• SSHProtection: Enables/Disables and configures the Invalid Access function

for SSH connections. When this item is enabled and excessive Invalid Access

Attempts via SSH are detected, then the VMR/NPS will lock out the offending

MAC address for the user-defined SSH Lockout Duration Period or until the /UL

command is issued. Note that for SSH protection, the lockout trigger is a function

of the SSH Hit Count parameter and the SSH Lockout Duration Parameter.

• LockoutEnable: Enables/Disables Invalid Access Lockout protection for SSH

connections. (Default = Off.)

• SSHHitCount: The number of invalid attempts that must occur during the

length of time specified by the SSH Lockout Duration period in order to trigger

the Invalid Access Lockout feature for SSH protocol. For example, if the SSH Hit

Count parameter is set to 10 and the SSH Lockout Duration parameter is set to

30 minutes, then the VMR/NPS will lock out the offending MAC address for 30

minutes when over 10 invalid access attempts occur during any 30 minute long

period. (Default = 20.)

• SSHLockoutDuration: This option selects both the length of time that an SSH

Lockout will remain in effect and also the time period over which invalid access

attempts will be counted. When an SSH Lockout occurs, the offending MAC

address will be prevented from establishing an SSH connection to the VMR/NPS

for the defined SSH Lockout Duration period. (Default = 2 Seconds.)

• TelnetProtection: Enables/Disables and configures the Invalid Access function

for Telnet connections. When this item is enabled and excessive Invalid Access

Attempts via Telnet are detected, then the VMR/NPS will lock out the offending

MAC address for the user-defined Telnet Lockout Duration Period or until the /UL

command is issued. Note that for Telnet protection, the lockout trigger is a function

of the Telnet Hit Count parameter and the Telnet Lockout Duration Parameter.

• LockoutEnable: Enables/Disables Invalid Access Lockout protection for Telnet

connections. (Default = Off.)

• TelnetHitCount: The number of invalid attempts that must occur during

the length of time specified by the Telnet Lockout Duration period in order to

trigger the Invalid Access Lockout feature for the Telnet protocol. For example,

if the Telnet Hit Count parameter is set to 10 and the Telnet Lockout Duration

parameter is set to 30 minutes, then the VMR/NPS will lock out the offending

MAC address for 30 minutes when over 10 invalid access attempts occur during

any 30 minute long period. (Default = 20.)

• TelnetLockoutDuration: This option selects both the length of time that a

Telnet Lockout will remain in effect and also the time period over which invalid

access attempts will be counted. When a Telnet Lockout occurs, the offending

MAC address will be prevented from establishing a Telnet connection to the

VMR/NPS for the defined Telnet Lockout Duration period.

(Default = 2 Seconds.)
