I've been trying to setup my laptop as a network troubleshooting box and I've run into a problem. I've got full network conectivity with my 575bt(ping,web,dns,etc) but when i try to set the interface into promisc mode at home I can't see any packets except those coming to the interface, But at work everything works fine. I've used the redhat packages, the 3.1.16 source , the standard redhat kernel(2.2.12-20), my own compiled 2.2.15 and 16 kernel's. But nothing works. The only thing I can track the difference between work and home to, is that at work I am hooking into a 10mb hub while at home I am hooking into a 10/100 hub and the 575bt is showing a link at 100MB. I've ruled out the hub since I can get tcpdump and ethereal to work on my other two linux machines. I was hoping someone might be able tell me if I am forgeting anything or if this could be a problem with the driver. I am stumped and any help would be appreciated.
