The Question is: We are trying to establish a TCP/IP connection between an Alpha 4100 and an IBM ThinkPad via a switch/hub and a DE450 or a DE500 NIC. (We have tried both !) The green 'Link' LED is lit and the amber 'Activity' LED flashes very briefly every 7 - 10 seconds. Invoking 'tcpip ping' fails with the error message 'no route available'. Using the Visio package on the ThinkPad to ping the Alpha also results in failure. We believe that we have not configured the NIC correctly for TCP/IP. The DE450 works fine to support user terminals via DECNet. Could you please direct us to documentation that will detail the TCP/IP configuration necessary. Thank you very much Regards Dave Buckingham (c/o Andy Blakeborough) The Answer is : TCP/IP Services configures the adapter correctly entirely automatically when the TCPIP$CONFIG tool is used -- as far as the host software is concerned. Information on configuring TCP/IP Services is included in the TCP/IP Services documentation, available in hardcopy and at the OpenVMS website: http://www.openvms.digital.com:8000/ If the other system uses DHCP, TCP/IP Services V5.0 and later can act as a DHCP Server. See other discussions here in Ask The Wizard for further information on operating in DHCP environments. The OpenVMS Wizard will assume that the green LED is illuminated on both the DE500 and the DE450 NIC, and that the reference to DECnet indicates that DECnet is operating on both NICs in the current system configuration, and not these NICs in some previous or difference system configuration. That the green LED is is illuminated and the amber LED is flashing would indicate that the NIC is functioning correctly. Given that DECnet is operating, the OpenVMS NIC device driver and the physical network also appear to be fully operational. The only host configuration settings required indicate to the NIC driver which interface to use (twisted pair, in this case), which speed to use, and the duplex mode to select. Again, that DECnet works indicates that the NIC is configured correctly and operating. For additional assistance with this, please contact your software support organization, your switch/hub support organization, or the Compaq Customer Support Center.
