tcpdump抓包提示：tcpdump: eht1: No such device exists

Question

CentOS6.5下使用tcpdump进行抓包

网卡信息：# ifconfig

eth1      Link encap:Ethernet  HWaddr 00:0C:29:22:D9:BC  
          inet addr:192.168.1xx.xxx  Bcast:192.168.103.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:fe22:d9bc/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:143238715 errors:0 dropped:31 overruns:0 frame:0
          TX packets:161956323 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:115399917729 (107.4 GiB)  TX bytes:80610840471 (75.0 GiB)

在linux下执行命令：tcpdump -i eht1 -w w2.pcap
提示：

tcpdump: eht1: No such device exists
(SIOCGIFHWADDR: No such device)

Answer 1

找到原因了：eth1写成eht1了。
