1. can0 已经存在：
# ifconfig -a
can0    Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
      NOARP  MTU:16  Metric:1
      RX packets:0 errors:0 dropped:0 overruns:0 frame:0
      TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
      collisions:0 txqueuelen:10
      RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
      Interrupt:26

错误如题：
#
# ip link set can0 up type can bitrate 125000 triple-sampling on
ip: either "dev" is duplicate, or "type" is garbage
#
#

后面也没法进行下去了。
# candump can0
-sh: candump: not found
#
#
