Yes, it seems to be running in half-duplex mode. Even if you are connected = to a switch that supports full-duplex (which seems not to be the case since auto-negotiation selected h-d), this setting is fine since full-duplex won't bring you a huge performance gain in most of the situations. > I wouldn't be too eager to do tests with this setting since this is a > production server and I have no direct physical access to it, so shutting > down the only interface by mistake is *not* an option ;-) I understand that :-) > But if I was to change it, how would I go about this without shutting down > fxp0? 'ifconfig fxp0 media 10baseT/UTP mediaopt full-duplex' ?? Yes, but I have never done that remotely (my FreeBSD machine is just under = my desk :-) Don't know whether this works over an ssh connection for example. = I am sure somebody else from the list has more experience in this regard ...
