I was running with tcpdump monitoring the TCP stream between my laptop her in Vancouver and my desktop system in California to try to figure out why I was seeing performance problems. I suspect that the packet capture triggered something as the problems were MUCH worse while I had tcpdump running in promiscuous mode. In any case, my stream locked up and I saw the following: # ifconfig wi0 wi0: flags=8943 mtu 1500 inet6 fe80::205:3cff:fe03:86b9%wi0 prefixlen 64 scopeid 0x3 inet 142.231.19.178 netmask 0xfffffe00 broadcast 142.231.19.255 ether 00:05:3c:03:86:b9 # wicontrol wicontrol: SIOCGWAVELAN: Operation not supported by device # dhclient wi0 ifconfig: ioctl (SIOCAIFADDR): Operation not supported by device wi0: not found exiting. ???? I unloaded if_wi and reloaded it and restarted dhclient and everything was fine. My ssh connections even survived. Any idea what the heck is happening here? -- R.
