Troubleshooting Cisco Internet Junction
Troubleshooting Cisco Internet Junction
Once the IJ gateway is running and the IJ client is installed, Winsock 1.1--based applications run automatically from the client computer. If problems occur, refer to the questions in this appendix to troubleshoot the problem. If an error message appears, refer to the appendix "Cisco Internet Junction Error Messages."
The following questions help to check the status of the IJ gateway and its TCP/IP software:
- Is the IJ gateway running?
- At the IJ gateway, open the Cisco Internet Junction window and select the Status menu item. Check that the outgoing broadcast count is greater than zero. A nonzero outgoing broadcast count indicates that the gateway is correctly sending SAP messages to the client.
- Is the IP address configured correctly?
- Enter the PING command from the MS-DOS prompt, specifying the gateway's own IP address or the standard loopback address, 127.0.0.1. If the command fails, the computer's IP address is incorrectly configured, and you need to reconfigure it.
- Can the computer connect to the external TCP/IP network?
- Enter the PING command, specifying a remote IP address or host name. If the command fails, check the modems, routers, and other hardware that connect your site with the Internet service provider.
- Is TCP/IP name-to-address resolution working?
- Enter the PING command, specifying a domain name such as cisco.com. If PING fails to return status information, check the following:
- Does the TCP/IP configuration at the gateway correctly specify the IP address of the Domain Name Server (DNS)?
- Is the Domain Name Server functioning correctly?
The following questions help to check for communication between the client and the gateway and for proper installation of the client software:
- Is the client receiving SAP messages from gateways?
- Open the Cisco Internet Junction window and pull down the Gateways menu. The menu should display names of IJ gateways. If one or more gateways are missing, check that the IPX configuration at the client and gateway use the same frame type, as described in the chapter "Installing a Cisco Internet Junction Client."
- Does the client have current versions of IPX components?
- The chapter "Installing a Cisco Internet Junction Client" lists versions of IPX components that IJ client software requires. If you did not check IPX component versions at installation, do it now.
- Are the configuration files correct?
- The Setup program modifies WIN.INI and SYSTEM.INI files on the IJ client. Refer to the section "Running the Setup Program" in the chapter "Installing a Cisco Internet Junction Client" and make sure that all changes described there have been made correctly.
- If the client is running Windows for Workgroups, does the frame type specified in NET.CFG match the frame type specified in PROTOCOL.INI?
- On Windows for Workgroups systems, problems often occur when NET.CFG and PROTOCOL.INI specify different frame types. If you did not check frame types at installation, refer to the section "Prerequisites for Installation" in the chapter "Installing a Cisco Internet Junction Client" and do so now.
