REFERENCE MANUAL, WEB, AND FAQ USING TELNET TO ACCESS THE COMMAND INTERFACE

REFERENCE MANUAL, WEB, AND FAQ

A detailed description of your router capabilities can be found in the Reference
Manual on the CD-ROM. A copy of this manual has been made on your hard disk
where the MultiCom Utilities EasyConfig and EditConfig have being installed.

Please also check the Technical Support area of our Web server at:

http://www.lightning.ch/support/

for future improvements in configuration, software, and the latest list of Fre­quently Asked Questions (FAQ). A short list of these can also be found in §3.

FINE-TUNING THE CONFIGURATION

For further configuration, you can use the router's built-in Web server at the
router's IP address (by default http://10.0.0.1/), or use the EditConfig™ Win­dows application, which both let you modify the configuration file generated by
EasyConfig.

2.3

2.4

CONNECTING TO THE COMMAND INTERFACE

For detailed control of the router, as well as interactive debugging and statistics,
you must use the Command Line Interface of your MultiCom. It can be reached
either through Telnet or with a direct console connection.

USING TELNET TO ACCESS THE COMMAND INTERFACE

If you MultiCom is correctly configured, you can run a Telnet program (e.g.
“C:\\WINDOWS\telnet”) to connect to it.

NOTE - By default your router has IP address 10.0.0.1

Pocket MultiCom — User’s Manual 27

2.5

2.5.1

CHAPTER 2GETTING STARTED CONNECTING TO THE COMMAND INTERFACE

USING THE CONSOLE

To use the console, you need either a terminal or a computer with a terminal emu­lation software (this is included with most computers, like “Programs”/“Accesso­ries”/“Hyper Terminal”™ with Windows™).

Once connected, your MultiCom displays its user interface on your terminal
screen. You can now auto-configure your MultiCom the commands “Upgrade
Key” (if needed) and “Setup”, or use EasyConfig with the “COM” port. You can
also reset the default configuration, as described in §4.

NOTE - If you see messages from the MultiCom in your terminal emulator win­dow, but cannot type-in commands, check that the terminal handshake is set to
“XON/XOFF”, instead of “RTS/CTS” or “Hardware”.

CHAPTER 3TESTING FREQUENTLY ASKED QUESTIONS (FAQ)

FREQUENTLY ASKED QUESTIONS (FAQ)

Please also consult the Technical Support area of the Lightning web site at:

http://www.lightning.ch/support/ for an up-to-date list of the FAQ.

1. The IP address of the MultiCom is 10.0.0.1 by default.

2. Can I connect my MultiCom router to a Fast Ethernet network? Your MultiCom router is built for 10 Mbps Ethernet, thus it will not work if

connected to a 100 Mbps-only Ethernet port. Most Ethernet ports can do both
10 and 100 Mbps Ethernet. Your router will work if connected to such a port,
but only when using a 4-wires cable like the grey Ethernet cable delivered
with your router.

3. Which Stac compression do you support?

We support the standard Stac LZS® compression (RFC1974). We do not sup­port the obsolete draft-09 version of Stac (sometimes called Stac-9) neither
Microsoft PPC (also know as MPPC or MS-Stac).

4. The ISDN line keeps up or opens periodically even if I don't access the Internet

3.1

There can be multiple causes for such a behaviour. First of all, make sure that
you have chosen a small timeout value for closing the line. The default value
is 90 seconds. If the line stays open longer than that, you may have an internal
problem (e.g. a misconfigured machine on your local network) or an external
problem (a misconfigured router talking to your

MultiCom). To find out where

the problem comes from, disconnect the Ethernet cable from the router and
check if the line still keeps up. If the line goes down after a few minutes, then
the problem is internal, if not then it is external. Use the command: Info

Site Internet Frames to check which IP packets are opening the line, and
Info Site Internet Frame

n

to display the most frequent one.

Common internal problems are:

• A mail program (e.g. Netscape, Eudora, MS Exchange) that is configured to
check mail every few minutes.

• A Web browser that has a starting page with an address that is outside your
network. Use a blank page or a local file as start page instead, e.g. file:/

mystartpage.html. Do not use an URL like http://localhost/mystart­page.html, as your computer will have to contact an external DNS server to

resolve the name “localhost”!

30 MultiCom LAN Access Center — User’s Manual

FREQUENTLY ASKED QUESTIONS (FAQ)

• A Web page that updates automatically. Some Web pages, e.g. home pages,
live images, update themselves automatically and can keep the line open.
Don't keep a window with such a page open while you are not using it.

External problems may be:

• You are talking to a MaxPro RWS-NT V1.0.0.4 router. That router recog­nises "Echo Requests" as traffic and incorrectly keeps the line up. If you can
make sure that the router on the other end of the line is a MaxPro RWS-NT
V1.0.0.4, put the command "PPP EchoRequest Off" into the part of the con­figuration file relating to that site.

• If it is another external problem, try contacting the owner of the router at the
other end of the line and make sure that the router does not send unsolicited
traffic. Try setting the timeout to a small value e.g. by adding the following
command to your configuration file: "ISDN IdleCloseTime 10".

5. I cannot connect to Telia with AutoConfiguration, why?

Telia is using the private A-class IP range 10.0.0.0, which is a non-routable
subnet that is also used locally by the AutoConfiguration setup! To connect
anyway, you can manually change the generated configuration to use the pri­vate B-class 192.168.0.0 subnet with SubnetMask 255.255.0.0. Such a
configuration is given in the e xamples section of the Reference Manual on the
CD-ROM.

6. When I use the SecureWall function, sending mail is very slow, why?

Some external mailers check the source port #113 to verify the identity of the
sender. Since the SecureWall drops unsolicited incoming packets, the mailer
will experience a timeout before giving up and accepting the mail anyway. If
you are in that case, you can simply map this port to the MultiCom, which will
signal that the port is not reachable and cause the mailer not to wait. To do so
add the following line to your configuration or chose the equivalent option in
the EasyConfig wizard:

IP Translation Map 113/tcp To <IP address of your MultiCom>

7. The SecureWall prevents some types of FTP connections.

As with most firewalls, FTP transfers can only succeed if the FTP program is
set to passive mode for gets and active mode for puts (these are standard in
Internet Explorer, Netscape, pftp, CuteFTP and Fetch in firewall mode).

8. Is the MultiCom LAN Access Center Year 2000 compliant? Yes

GENERAL TROUBLE-SHOOTING SCHEME

In case of connection problems, just looking at the signals behaviour can give
useful hints for finding your configuration problem. A general scheme, valid for
AutoConfiguration setting with DHCP and SIUA is shown below:

CONNECTING TO A DISTANT SITE

CONNECTING TO A DISTANT SITE

Connecting to a distant site using Telnet, FTP, Ping, a Web browser, or your par­ticular software is the quickest and easiest ways to ensure that your Ethernet and
ISDN connections are both functioning correctly:

If you could not connect, try connecting to another site to make sure that the prob­lem does not reside on the other side of the line. If you can not connect on your
second attempt, carry out the following tests.

CHECKING THE ETHERNET CONNECTION

You can use either a Web-browser, Telnet, FTP or ping, specifying the IP address
of your MultiCom LAN Access Center, to connect to it directly. If the connection
opens, this confirms that your Ethernet software is working correctly.

3.3

3.4

If the connection does not open, make sure that you typed in the correct IP
address. If you did, there is probably a problem with either the configuration of
your MultiCom LAN Access Center or your computer. Refer to § 3.2, "General
Trouble-Shooting Scheme" on page 32 for details.

If you still can’t access your MultiCom LAN Access Center, you can reset it to fac­tory default address 10.0.0.1 and DHCP mode by following section 4.3 on page

37.

CHECKING THE ISDN CONNECTION

Carry out the following test if your Ethernet connection is functioning correctly
but you cannot connect to a distant site:

1. Run Telnet or a console connection, specifying the IP address of your

MultiCom LAN Access Center, following instructions in section 1.3 on page 9.

3.5

MultiCom LAN Access Center — User’s Manual 33

CHAPTER 3TESTING FURTHER TROUBLE-SHOOTING

2. The connection opens and asks for the user name and password, if set.

3. At the next prompt, type in the following command: ISDN Conn
A B-channel signal should turn green, indicating a successful connection.

If the ISDN connection is not OK, check the configuration of your MultiCom for
problems. Check also to see if there is a problem with your telephone wires.

If the ISDN connection is OK, but you still cannot connect to a distant site, it is
probably because there is either a problem with your computer’s configuration, or
with the configuration of the other site’s router or computer.

FURTHER TROUBLE-SHOOTING

Please refer to the Reference Manual for further trouble-shooting. Especially, try
first the Diagnose command:

1. Run a Web-browser, specifying the IP address of your MultiCom.

2. The connection opens and asks for your user name and password, if set.

3. The MultiCom LAN Access Center home-page appears.

4. Click on the link: “Diagnostics”, corre­sponding to the Diagnose command.

5. You will receive basic diagnostics: Follow the suggestions provided.

6. You may need to run Telnet, specify­ing the IP address of your MultiCom

LAN Access Center, logging-in, and typing some “info” commands, like:

3.6

¥ isdn info ¥ isdn info history ¥ site stats Internet
¥ ppp info ¥ ppp info all ¥ site info internet frames
¥ dhcp info ¥ info ip ¥ site info internet frame
¥ dns info ¥ info ip router ¥ info site internet
¥ cat boot.rpt ¥ ip siteAddr info ¥ ip translation info

These commands and more are documented in the “Commands” chapter of
the Reference Manual on CD, including also a trouble-shooting chapter.

Configuration

This chapter describes how to install your MultiCom
LAN Access Center in order to set the configuration
for the first time or to modify the existing configura­tion. It also provides instructions for resetting the
default configuration.

CHAPTER 4CONFIGURATION INSTALLING FOR CONFIGURATION

INSTALLING FOR CONFIGURATION

Configuring your MultiCom LAN Access Center for the first time can be done with a
direct console port connection or a direct Ethernet connection.

NOTE - For a direct connection, you need either a terminal or a computer with a
terminal emulation software (this is included with most computers). the serial port
of your computer must have a specific configuration, see Figure 3 on page 10 for
details.

Once the start-up process is finished, your MultiCom LAN Access Center will dis­plays its user interface on your screen. You can now configure your MultiCom LAN

Access Center using the “EasyConfig” Windows wizard or manually, according to

the instructions in the “Configuration” section of the Reference Manual.

4.1

DEFAULT CONFIGURATION

When shipped, your MultiCom LAN Access Center has a default configuration file,
with the following informations set:

• IP address of the router: 10.0.0.1

• No User Account

• ISDN NumberEnabled: * (all)

• Site protocol: PPP

• Authentication: None

• DHCP server: On

This allows you to connect to your MultiCom without security checking, either
from Ethernet or the console, for local configuration, or from the ISDN connec­tion, for remote configuration.

4.2

36 MultiCom LAN Access Center — User’s Manual

RESETTING THE DEFAULT CONFIGURATION

CA UTION — All these parameters must be changed later to suit your

needs. In particular, it is strongly advised to create a user

account , for security reasons!

NOTE - You cannot access the private 10.0.0.1 address, unless you are in the

same IP subnet. You must either use the console to change it, change your own IP
address to be in the same subnet as your MultiCom, or configure your computer to
be a DHCP client.

RESETTING THE DEFAULT CONFIGURATION

If you want to return to a safe configuration or if you have forgotten your pass­word, you can temporarily restart your MultiCom in its default configuration by
using the console:

1. Install your MultiCom LAN Access Center for a console connection, as
described in § 1.1, "Checking Your Package Contents" on page 8.

2. During the start-up operation — when all left LEDs are blinking orange
— press the minus key ( -) 10 times.

Upon initialization, your MultiCom LAN Access Center will be reset to the
default configuration.

You can then start a new configuration or upload a backup of the last working
configuration.

4.3

NOTE - For that reason, always keep a backup of your working configuration.

MultiCom LAN Access Center — User’s Manual 37

CHAPTER 4CONFIGURATION RESETTING THE DEFAULT CONFIGURATION

To permanently reset your MultiCom L AN Access Center with the default configu­ration, follow the standard set of instructions for modifying configuration, as
described in the “Config” section of your Reference Manual.

NOTE - The user’s configuration file is not overwritten by this manipulation. It
will be available again the next time you reboot your MultiCom.
