Hello All, I am usually in the habit of forcing my network servers to 100 Mbps Full Duplex instead of rolling the dice with auto negotiation (Netware and NT/W2K boxes). We have had some problems in the past and forcing them leaves nothing to question. I have done some googling and looked for how to do this on Linux. I have seen some refernces to a options 0x16 or 0x32 and also some stuff like 100FD added to the config. I have a couple of questions for the group. 1. Is it a good or bad idea to force duplex on Linux? 2. If good, does anyone know the correct syntax and where to add it or at least a good source to find the answer? Is this specific to the NIC you have in the box? 3. When I do an ifconfig I don't see it listed as to the mode 100 full or half, is there anyway to determine this? I am running RH 7.1, 2.4 kernel with a Intel Pro 100 nic. Regards, rotbau
