testing a new USB network interface adapter on my laptop so i first
took down the regular wired interface:
# ifdown eth0
disconnected the network cable, plugged it into the adapter and
plugged the adapter into one of the ports on my linksys compact 4-port
hub, at which point eth1 came up nicely:
# ifconfig eth1
eth1 Link encap:Ethernet HWaddr 00:60:6E:00:DE:F0
inet addr:192.168.1.217 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::260:6eff:fe00:def0/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:3 errors:0 dropped:0 overruns:0 frame:0
TX packets:9 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:702 (702.0 b) TX bytes:1212 (1.1 KiB)
#
whereupon i went to take it down again, only to get:
# ifdown eth1
usage: ifdown <device name>
#
on the other hand, ifconfig works just fine:
# ifconfig eth1 down
apparently, neither ifup nor ifdown work on the USB net interface
(they work fine for the regular eth0), but the full incantation of
"ifconfig up" and "ifconfig down" work just fine. is this anything to
care about?
