I was unable to see any messages on boot regarding DHCP. Here is what dmesg says about the NIC. fxp0: <Intel EtherExpress Pro 10/100B Ethernet> rev 0x0c int a irq 17 on pci0.1 3.0 fxp0: Ethernet address 00:02:b3:1a:b2:81 I do get this at the end though. Is this the DHCP info you were looking for? arp: 00:30:65:a6:a4:f8 is using my IP address 0.0.0.0! arp: 00:30:65:a6:a4:f8 is using my IP address 0.0.0.0! I think that ethernet address is the cable modem, which is a Motorola SB4100 Surfboard, because I only have one NIC. Is there a way to find out for sure? My Windows 98SE TCP/IP is as follows: Bindings Novell Netware Client (used at college, cable doesn't use it) Advanced None NetBIOS I want to enable NetBIOS over TCP/IP (only used at college I think) DNS Config Disable DNS Gateway Empty WINS Config Disable WINS Resolution (Use DHCP is not checked) IP Address Obtain automatically Internet options has: Automatically detect settings Use a proxy server In Netscape I had to add in Manual Proxy Configuration HTTP proxy Port 8080 I don't think I am using DHCP in Windows. Is there a way I can enter a gateway, subnet mask, and IP address manually for my NIC? I can get the values from winipcfg. I used tcpdump with the options you suggested after running dhclient. Here is the output. 08:32:46.919578 0.0.0.0.bootpc > 255.255.255.255.bootps: xid:0x3c77524f [|bootp] 08:34:03.533741 0.0.0.0.bootpc > 255.255.255.255.bootps: xid:0x4a42dd2b [|bootp] 08:34:03.538512 hes1.buf.adelphia.net.bootps > 255.255.255.255.bootpc: xid:0x4a4 2dd2b Y:ny-chicagost1a-176.buf.adelphia.net S:hes1.buf.adelphia.net [|bootp] (DF ) Anything else I should try?
