yum install wireshark
抓包命令tshark --help,这个会有屏幕上显示,因为我用的是最小化系统安装,故用tshark命令
tshark -i eth0
如果要保存加-w 文件名.pcap也可以指定路径,如果不指定默认保存在当前目录下
tshark --help得到如下提示:
- -w <outfile|-> write packets to a pcap-format file named "outfile"
- (or to the standard output for "-")
- -W n Save extra information in the file, if supported.
- n = write network address resolution information
例子:
- [root@VM3 data]# tshark -w t1.pcap -i eth0
- Running as user "root" and group "root". This could be dangerous.
- Capturing on eth0
- 36 C
达到你要的包数按ctrl+c退出即可
- [root@VM3 data]# tshark -w t1.pcap -W n -i eth0
- Running as user "root" and group "root". This could be dangerous.
- Capturing on eth0
- 48 C
达到你要的包数按ctrl+c退出即可
最后用sz命令把抓到的包下载下来,用windows的Wireshark打开即可
