问题描述
我有一个pcap文件要重播.我想重写数据包有效载荷以包含时间戳.如何使用 tcpreplay 或 tcprewrite ?是否有默认选项，还是我应该自己实现(修改tcpreplay)?我已经阅读这些页面一段时间了，谷歌也没有帮助我.预先感谢
I have a pcap file to replay. I want to rewrite packet payload to include a timestamp. How can I do that with tcpreplay or tcprewrite? Is there a default option or should I implement it myself (modifying tcpreplay)? I have been reading these pages for a while and google did not help me either. Thanks in advance
PS:我不想修改数据包的原始大小，因为数据并不重要，覆盖就可以了.如果唯一的选择是修改数据包大小，那我也可以.
PS: I don't want to modify the original size of the packet, since the data is not important overwriting is fine. If only option is to modify packet size, I am fine with that too.
推荐答案
tcpreplay/tcprewrite不支持这种编辑，因此您必须自己编写代码.如果您不介意破坏数据包数据(听起来还可以)，那么通过编辑tcpedit.c应该很容易.
That kind of editing isn't supported by tcpreplay/tcprewrite, so you'd have to write the code yourself. If you don't mind corrupting your packet data (which sounds like you're ok with) then it should be pretty easy by editing tcpedit.c.
