2.1.3 Web Management Interface
The IP serial console supports both HTTP and HTTPS (HTTP over SSL) protocols. The user must authenticate themselves by
logging into the system with a correct user name and password
To access the IP serial console Web management pages, enter the pre-set IP address or resolvable hostname into the web
browser’s URL/Location field. This will direct the user to the login screen.
Figure below shows the user homepage of the Web management interface. A menu bar, provided on the left hand side of the
screen. Selecting an item on the menu bar opens a tree view of all the submenus available under each grouping. Selecting a
submenu item will allow the user to modify parameter settings for that item.
Every page will allow the user to Save to flash, Apply or Cancel their actions. To apply all changes made, the user must select Apply.
Only when the user selects Apply will the new parameter values be applied to the IP serial console configuration and
go effective. But new settings are not saved to non-volatile memory (Flash) unless user clicks Save to flash button.

User can do the network IP settings via V-100 or web pages. This chapter describes the usage of web pages. The default IP settings are
as follows.
2.2.1 IP Configuration
The IP serial console requires a valid IP address to operate within the user’s network environment. If the IP address is not
readily available, contact the system administrator to obtain a valid IP address for the IP serial console. Please note that the
IP serial console requires a unique IP address to connect to the user’s network.
There are two types of IP assignments user can choose from:
■Static IP
■DHCP (Dynamic Host Configuration Protocol)
The IP serial console is initially defaulted to Static IP mode, with a static IP address of 192.168.0.1.
*The onfiguration setting will not go into effect until clicking the button Save to flash & reboot.
2.2.2 SMTP Configuration
The IP serial console (IP SERIAL CONSOLE SERVER) can send an email notification when the number of system log
messages reaches to certain value and/or when an alarm message is created due to an issue with serial port data.
The user must configure a valid SMTP server to send these automatically generated emails.
The “device mail address” must be registered to SMTP server.
The IP serial console supports two SMTP server types:
■SMTP without authentication
■SMTP with authentication
The SMTP user name and SMTP user password are required when selecting SMTP with Authentication.
Secondary SMTP configuration is also provided so that mail can be delivered even when the primary SMTP server fails.
Only when the primary SMTP server fails, the secondary SMTP server will be tried for mail delivery.

2.3.1 IP Filtering
The IP filtering function keeps unauthorized hosts from accessing to the IP serial console by specifying IP filtering rules. It is
important to fully understand what an IP filter is. If you don’t fully understand this, you will get unexpected results against your
original plan.
The IP address/ Mask specifies the host range by entering base host IP address followed by / and subnet mask. The host IP
addresses to be filtered based on the rule defined. The table below gives examples of IP address/ Mask settings.
Specified host range Base Host IP address Subnet mask
Any host 0.0.0.0 0.0.0.0
192.168.1.120 192.168.1.120 255.255.255.255
192.168.1.1 ~ 192.168.1.254 192.168.1.0 255.255.255.0
192.168.0.1 ~ 192.168.255.254 192.168.0.0 255.255.0.0
192.168.1.1 ~ 192.168.1.126 192.168.1.0 255.255.255.128
192.168.1.129 ~ 192.168.1.254 192.168.1.128 255.255.255.128
The Port is a port or port range of the IP serial console which hosts try to access to.
Chain rule
The chain rule determines whether the access from the hosts is allowed or not. It can be one of the these two values :
■ACCEPT : access allowed
■DROP : access not allowed
When the IPCS receives a TCP packet, it will process the packet with the chain rule depicted below. The process ordering is
important; The packet will enter the chain rule 1 first, if meet the rule then take action directly, otherwise go to chain rule 2.

2.3.2 IP Filtering
Users can add a new IP filtering rule by setting the properties at adding line and then clicking the button Add. User can remove
a rule by clicking the button Remove.
In the example above, no host is allowed to connect to the IPCS through http (port 80) by the #3 rule but the hosts whose
subnet is 192.168.1.x is allowed by the #1 rule and 192.168.2.x by the rule #2. So, only the hosts which elong to the subnet
192.168.1.x or 192.168.2.x can access to the IPCS through http by the #1, #2 and #3 rules.
The IP serial console Web server supports both HTTP and HTTPS (HTTP over SSL) services simultaneously. Users can select
user authentication method for the IPCS web pages login. The IP serial console currently provides authentication methods of
Local and RADIUS.
2.4.1 Local
The IP serial console always refers to the local database for the web server login user authentication.

2.4.2 Dynamic DNS
When users connect the IP serial console to a DSL line or use a DHCP configuration, and get a dynamic IP address from the
network, the IP address may not the same as previous. It can therefore be very difficult to know if an IP address has changed,
or what the new IP address is.
A Dynamic DNS service is provided by various ISPs or organizations to deal with the above issue. By using the Dynamic DNS
service, users can access the IP serial console through the hostname registered in the Dynamic DNS Server regardless of any
IP address change.
By default, the IP serial console only supports Dynamic DNS service offered at Dynamic DNS Network Services, LLC
(www.dyndns.org).
To use the Dynamic DNS service provided by Dynamic DNS Network Services, the user must set up an account. In their
Members’ NIC (Network Information Center - http://members.dyndns.org). The user may then add a new Dynamic DNS Host
link after logging in to their Dynamic DNS Network Services Members NIC.
After enabling the Dynamic DNS service in the Dynamic DNS Configuration menu, the user must enter the registered Domain
Name, User Name, and Password. After applying the configuration change, users can access the IP serial console using only
the Domain Name. The DNS (Domain Name Systems) is the internet service that translates your domain names into IP addresses.
2.4.3 HTTPS / SSL
The IP serial console Web server supports both HTTP and HTTPS (HTTP over SSL) services simultaneously.
The user can to enable or disable security function of each port individually. HTTPS provides a secure, encrypted web interface
over SSL (secure sockets layer). The following steps to use the HTTPS protocol:
1. Change the URL from “http://xxx.xxx.xxx/” to “https://xxx.xxx.xxx/”.
2. If connect success, it will show up the “Lock” icon on the right-hand side of the taskbar.

2.4.4 RADIUS
Authentication is the process of identifying an individual, usually based on a username and password. The IP serial console
supports various authentication options, such as Local, RADIUS, to authenticate the users who access the serial port. When
the authentication is set to Local, the IP serial console will use its own user list to authenticate a user. If configured otherwise,
the IP serial console will request authentication from the external authentication servers (i.e. RADIUS).

CS-116
Console Server Mode
Configuring a serial port as a console server creates a TCP socket on the IP serial console unit that listens for a Telnet or SSH client
connection. When you connect to the TCP socket, you have access to the device attached to the serial port as if the device were
connected directly to the network. Data stream can be sent back and forth between the device and the Telnet/SSH client program.
Raw TCP is also supported with the Console Server Mode.
For console server mode, the user can configure the following parameters:
Listening TCP port number
The user can also access a serial port through the IP address of the IP serial console and the listening TCP port number of the serial
port. If the IP address of the IP serial console and the serial port are assigned as 192.168.123.100 and listening TCP port number
4001, the user can connect to the port as follows: telnet 192.168.123.100 4001
Protocol
Select Telnet, SSH or Raw TCP as the protocol. If the users are using a Telnet client program, select Telnet. If the users are using an
SSH client program, select SSH. When Raw TCP is selected, direct TCP socket communication is available between the IPCS
and the remote host.
Inactivity timeout
In order to avoid a client holding a TCP connection while no data transferring on the serial port for long time. If the inactivity timeout is
enabled, and no data activity between the IP serial console and the Telnet/ SSH client for the specified inactivity timeout interval
(no data activity in the serial port), the existing TCP session will automatically be closed. If the user wants to maintain the connection
indefinitely, configure the inactivity timeout period to 0.
TCP Keep-alive (no configuration required)
In order to avoid TCP connection lockup, the IP serial console will continue to check the connection status between the Telnet/ SSH
client and the IP serial console by sending “keep alive” packets periodically. If the Telnet/ SSH client does not answer the packets in a
period of time, system will assume that the connection is down unintentionally. The IP SERIAL CONSOLE will close the existing Telnet/
SSH connection, regardless of the inactivity setting. So the TCP connection won’t be deadlocked when user’s application closed
improperly or the network link interrupted.
Terminal Server Mode
In terminal server mode, the IP serial console will unit’s serial port is configured to wait for data from the device connected to the port.
If data arrive is detected, the IP SERIAL CONSOLE unit starts a TCP session as a Telnet or SSH client to a pre-defined server. The
server must be defined by you before the port can be configured for a Telnet or SSH client. This mode is used when you want to
access servers on the network from a serial terminal. Raw TCP is also supported with the Terminal Server Mode.
Dial-in Modem Mode
In this mode, the IP serial console unit assumes an external modem is attached to the serial port and is waiting for a dial-in
connection from a remote site. When a user dials-in using a terminal application, the IP serial console unit accepts the connection
and displays the appropriate prompt or menu for you that logged in.

2.5.5 Serial Port Parameters
To connect the serial device to the IPCS serial port, the serial port parameters of the IP serial console should match exactly to
that of the serial device attached.
2.5.6 Port Logging
With the Port logging feature while in console server mode, the data receiving from the tracking serial port will be buffered in
IP serial console memory. The user can also define keywords for each serial port that will trigger an email notification if the
keyword is found in the logged data. This will enable the user to monitor the data from the attached device. The Port logging
feature is valid and visible only if the operation mode of the serial port is configured to console server mode.
