<div>It's probably the "libuinet" component you're looking for,
but that's an active userland TCP stack, not a passive one.
That is, you can do full TCP/IP with libuinet pretty easily,
but you can't just hand it packets and look at a stream you're
intercepting. It might be possible to make it provide two
half-connections for each connection from the wire at some
point, with data going into a socket and being readable, but
that functionality isn't there now. I know there's some
interest in funding Pat Kelsey (who did the "libuinet" work)
to do that, but I don't think there's any roadmap for it. I
may also be misunderstanding what you're using libnids to do.</div>

I think you're right on point.<br>
<br>
Basically what I need is the ability to write something like
<a class="moz-txt-link-freetext" href="https://github.com/alfredperlstein/dsniff/blob/master/urlsnarf.c">https://github.com/alfredperlstein/dsniff/blob/master/urlsnarf.c</a>
using wanproxy as a backend.<br>
<br>
Specifically have a look at line 164 of the file at
<meta charset="utf-8">
sniff_http_client(), this calls line 88 of that file
<meta charset="utf-8">
(process_http_request()) each time a new packet comes in for a
stream we are interested in. It's relatively basic stuff to monitor
streams. Is it at all possible to do this using wanproxy libuinet?<br>
<br>
If not is Pat available to chat about what needs to be done?<br>
<br>
thank you,<br>

I'm wondering is there overlap in the functionality such
that I could drop it in place for the backend for dsniff's
suit of utils, specifically urlsnarf.<br>
