hook - C# How would I intercept all packets and find out the IPs through hooking? -

-

actually have 3 questions:

1- according nazar grynko answer, intercepting 3 functions(send , recv,and connect) me anticipate packet in machine?

2- if hooked 3 functions, how intptr points sockaddr structure p/invoked native function?

3- send, , recv not having sockaddr, how figure out addresses?

thank in advance.

  1. the functions described part of posix standard. means when use these functions on windows, you're calling wrapper translates system call. can send packets without use of function (e.g, using windows api).

  2. see answer number one. won't you. you'd have provide hook processes.

  3. the functions describe use file descriptor posix construct, , user-mode simulated on other systems.

to inspect traffic must use driver you. might want @ pcap.net c# project aimed @ problem, , provides driver , api necessary.

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
