Setup guide

SSH Server
Telnet Server
NTP Client
Dynamic DNS
System Log
SSH (http://en.wikipedia.org/wiki/Secure_Shell) Server: the following AirOS Device
SSH Server parameters can be set there:
Enable SSH Server: This option enables SSH access to the AirOS Device.
Server Port: SSH service TCP/IP port setting.
Enable Password Authentication: when enabled, you must authenticate using
Administrator credentials in order to grant SSH access to the device, otherwise
an Authentication Key will be required.
Authorized Keys: To Import a Public key file working to get SSH access to the
device instead of using an admin password, press the “Browse” button and select
the key file, then press “Import” button. Finally press the “Save” button.
Telnet Server
Telnet Server: the following AirOS Device Telnet Server parameters can be set there:
Enable Telnet Server: This option activates the Telnet access to the AirOS Device.
Server Port: Telnet service TCP/IP port setting.
NTP Client
NTP Client: The Network Time Protocol (NTP) is a protocol for synchronizing the
clocks of computer systems over packet-switched, variable-latency data
networks. It can be used to set the AirOS system time. System Time is reported
next to the every System Log entry while registering system events if Log option
is enabled.
Enable NTP Client: control will enable NTP client.
NTP Server: specify the IP address or domain name of the NTP Server.
Dynamic DNS
Enable Dynamic DNS: mark this checkbox to enable Dynamic DNS service for
the AirOS device. Dynamic DNS is a network service providing which allows
real-time notification to the DNS Server of any changes occurring in the device’s
IP setting, there by allowing access to the device through a Domain Name even
if the device’s IP address has changed.
Host Name: defines the Dynamic DNS Host Name. A large list of Dynamic DNS
services is available here (http://www.dmoz.org/Computers/Internet/Protocols
/DNS/DNS_Providers/Dynamic_DNS/) .
Username: defines the Dynamic DNS Username.
Password: defines the Dynamic DNS password. Check “show” to display the password.
System Log
Enable Log: This option enables the registration routine of the system log
messages. By default it is disabled.
Enable Remote Log: enables the syslog remote sending function while
System log messages are sent to a remote server specified by the Remote
Log IP Address and Remote Log Port.
Remote Log IP Address is the host IP address where syslog messages
should be sent. Remote host should be configured properly to receive syslog
protocol messages.
Remote Log Port: is the TCP/IP port of the host syslog messages should be
sent. "514" is the default port for the commonly used system message
logging utilities.
Every logged message contains at least a System Time and a Host Name. Usually a particular service name which generates the system
event is specifies also within the message. Messages from different services have different context and different level of the details.
Usually error, warning or informational system services messages are reported, however more detailed Debug level messages can be
reported also. The more detailed system messages are reported, the greater volume of log messages will be generated.
