If you are having trouble making an IP connection to a remote computer, or trouble receiving them, please review the following tips for a solution to your problem.
Do Not Control Your Local Computer over TCP/IP
Timbuktu Pro does not support Control connections to your own computer.
No TCP/IP Connection Tab
If the TCP/IP connection tab does not appear in the main Timbuktu Pro window, make sure that your TCP/IP software is compatible with Timbuktu Pro. Refer to the Timbuktu Pro Release Notes for the most up-to-date information.
If you are using an approved IP stack, make sure that your IP network software is working properly outside of Timbuktu Pro. Try other Windows Sockets IP applications, such as Netscape, Telnet, or FTP. If these aren't working either, the problem is more likely to be with your IP stack than with Timbuktu Pro.
Error Message: Computer Name Does Not Match
If you connect to an address saved in an address book and the computer name is an incorrect computer, the address book may have saved a dynamic IP address. That address may have since been assigned to a different computer. If your organization uses dynamic IP addressing, you may not want to use the address books.
Cannot Connect to a TCP/IP Address
If you cannot connect to an TCP/IP address, check the following:
Make sure that you are entering the TCP/IP address correctly.
Can other computers connect to the remote Timbuktu Pro computer? Can this Timbuktu Pro computer connect to another Timbuktu Pro computers?
If you can access the Internet, try observing Netopia's Timbuktu test machines at 163.176.1.105 or 163.176.1.71.
Make sure the TCP/IP address you are using is current. If the remote computer is using dynamic TCP/IP addressing, the address may have changed. Please call or email the user to find out their current TCP/IP address.
Make sure you are able to connect to other Timbuktu Pro computers using TCP/IP. If not, the problem may lie with your TCP/IP configuration.
Can you use the ping utility and "ping" the remote machine? A response of "request timed out" indicates you do not have a TCP/IP connection between the two machines.
Given below are a few reasons why you may be unable to connect to a TCP/IP address:
TCP/IP is not configured correctly.
The computer is not connected to the Internet.
There is a Firewall. For more information, see Firewalls.
There is a misconfiguration on a router or the physical connection. If only some of the packets come back, it usually indicates a problem such as bad cabling, a slow Internet connection, or a busy network connection.
Possible Solutions
If you entered a DNS name, try using the numerical TCP/IP address instead.
The remote computer may not be accessible because of a security firewall on your network or on the remote network. To determine whether Timbuktu can use TCP/IP on your network, check with your Network Administrator to see if there is a firewall. The Trace Route utility can often indicate a firewall or other routing problems. If you can not Trace Route to the machine, you probably will not be able to connect to it either.
To use Trace Route, type "tracert <tcp/ip address>" at a DOS prompt. For example, "tracert 123.156.7.8". The response will give the TCP/IP address of every router between you and the remote address and the time it took to reach that router.
For more information, see Firewalls or the technical note on Netopia's Web site at http://www.netopia.com/support/technotes/software/tb2mac/TPM_031.html.
Are you using Dial Up Networking or a Point to Point Protocol (PPP) connection? Do other TCP/IP applications, like FTP or your Browser, work over the dial up connection? If you need a PPP server, the Remote Access Server (RAS) that ships with Windows NT is recommended. Please refer to Microsoft documentation for proper configuration.
If you have selected a Macintosh computer, make sure it has TCP/IP incoming access turned on.
Make sure the computer you selected is running a compatible version of Timbuktu Pro.
For more tips on configuring TCP/IP for Macintosh, please see the technical note at http://www.netopia.com/support/technotes/hardware/NQG_004.html.
Connection Tips
You may experience problems during a remote control session if you use any service (Control, Observe, Send, or Exchange) with the same computer you are controlling or observing.
Warning: Do not attempt to control or observe your own computer over TCP/IP; it will crash your system.
