When a packet driver will send but not receive packets, it is almost always interrupt-related. Be sure of two things: 1) that you are specifying the same interrupt that the hardware is using, and 2) that there are no interrupt conflicts. Many Ethernet cards default to interrupt 3, which is used by the second serial port. NCSA Telnet comes up with the error message: "Warning, packet driver vector incorrect, using default search" when run. The config.tel entry we've been using is: hardware=packet interrupt=0x60 ; (set with wd8003e.com as ) and we've tried other software interrupts, in case that was the problem. We've also tried including various other items in the congif.tel (like the ioaddr and mem. address of the card) with no further success. When you use hardware=packet, comment out all hardware-related parameters, such as interrupt=, membase=, etc. Telnet can determine them on its own. One more thing: Has anyone heard about packet drivers which will respond to snmp queries from the net? That is a large reason we are looking at using packet drivers rather than NCSA's built-in interface. I know that Cabletron is doing something in that vein, but I know nothing more than that. -- --russ I'm proud to be a humble Quaker.
