tcpdump: no suitable device found

Transferred from http://blog.sina.com.cn/s/blog_ 7d49c18001014 vgg.html

1、tcpdump: no suitable device found

Problem analysis and solution:

There are two reasons:
1. The permissions are not enough and are not processed generally. Only the root user can use tcpdump , sudo. / tcpdump
2. By default, only four tcpdumps can be used at the same time. If they are used up, this kind of error will be reported. We need to stop the extra tcpdump

2、

In Fedora 14, sudo
should be added to run the make install command

3、

Linux uid or euid of 0 required

It’s also a matter of authority. Add sudo under fedora
