You haven't shown us netstat -in, so we don't know if there are any collisions or other errors being racked up. You also don't say if the NIC is plugged directly into the ISDN router or if both are connected to a hub. If it is connected directly, check that the cable is terminated properly (i.e. that it hasn't been set up as a "straight through" cable, where all four pairs of wires are lined up one right after the other, 1-2, 3-4, 5-6, 7-8 -- this is not how it's supposed to be done, and I have to ask you to check this as I still run into improperly terminated patch cables every so often, much to my neverending astonishment). Do me the following: - With the machine running, type the following, as root: ifconfig xl0 media 10baseT/UTP - Unplug the ethernet cable that connects the NIC to the ISDN router. - Wait 5 seconds. - Plug the cable back in. - Try again. - Watch what happens. - Tell us what you see. -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "It is not I who am crazy; it is I who am mad!" - Ren Hoek, "Space Madness" ============================================================================= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
