Services

The Services page allows you to control remote management access to the switch
and to configure of NTP time servers.

Remote Management

Settings

The SSH, Telnet, Web, and SNMP management interfaces are enabled and open to
access from the Internet. To provide more security, specific services can be disabled
and management access prevented from the Internet.

SSH

The Secure Shell (SSH) can act as a secure replacement for Telnet. The SSH protocol
uses generated public keys to encrypt all data transfers passing between the access
point and SSH-enabled management station clients and ensures that data traveling
over the network arrives unaltered. Clients can then securely use the local user
name and password for access authentication.

Note that SSH client software needs to be installed on the management station to
access the access point for management via the SSH protocol.

Figure 40: SSH Server Settings

The following items are displayed on this page:

◆

SSH Server

— Enables or disables SSH access to the access point.

(Default: Enabled)

◆

Port

— Sets the TCP port number for the SSH server on the access point.

(Range: 1-65535; Default: 22)

◆

Allow SSH from WAN

— Allows SSH management access from the WAN.
