Hey Guys,
I have placed Keystroke loggers on a few sensitive machines on my network
and am trying to send data from target machines to a web server using IE
Send() function. Can somebody suggest me a robust and intelligent method to
capture such data on the web server which is not very processor intensive.
Thanks for guidelines.

Subject: Re: to dsniff or not to dsniff
I've finally tried to get all this working from source, I've got
libnet 1.0.2a compiled ok but when I come to compile libnids 1.16 I
get the following errors:
for dir in src samples ; do (cd $dir ; make all) ; done
make[1]: Entering directory `/usr/src/libnids-1.16/src'
gcc -c -g -O2 -D_BSD_SOURCE -D_BSD_SOURCE -D__BSD_SOURCE -D__FAVOR_BSD
-DHAVE_NET_ETHERNET_H -Wall -DHAVE_ICMPHDR=1 -DHAVE_TCP_STATES=1
-DHAVE_BSD_UDPHDR=1 -I. ip_options.c
ip_options.c:31:2: error: #error "unknown byte ordering"
ip_options.c:83:2: error: #error "unknown byte ordering"
ip_options.c: In function 'ip_options_compile':
ip_options.c:113: error: 'struct iphdr' has no member named 'ihl'
ip_options.c:213: error: 'struct timestamp' has no member named 'flags'
ip_options.c:271: error: 'struct timestamp' has no member named 'overflow'
ip_options.c:277: error: 'struct timestamp' has no member named 'overflow'
make[1]: *** [ip_options.o] Error 1
So I added -DLIBNET_LIL_ENDIAN to the makefile and tried again, got a
bit further and got:
gcc -c -g -O2 -D_BSD_SOURCE -D_BSD_SOURCE -D__BSD_SOURCE -D__FAVOR_BSD
-DHAVE_NET_ETHERNET_H -Wall -DHAVE_ICMPHDR=1 -DHAVE_TCP_STATES=1
-DHAVE_BSD_UDPHDR=1 -DLIBNET_LIL_ENDIAN -I. killtcp.c
killtcp.c: In function 'nids_killtcp':
killtcp.c:17: error: 'IP_H' undeclared (first use in this function)
killtcp.c:17: error: (Each undeclared identifier is reported only once
killtcp.c:17: error: for each function it appears in.)
killtcp.c:17: error: 'TCP_H' undeclared (first use in this function)
At this point I'm assuming that either I've missed something or
something is wrong. Is there anyone out there who has got this
compiled from source and, if so, can you give any tips?
Thanks
Robin
PS The distro is Arch, gcc -v gives:

Target: i686-pc-linux-gnu
Configured with: ../gcc-4.0.3/configure --host=i686-pc-linux-gnu
--build=i686-pc-linux-gnu --prefix=/usr --enable-shared
--enable-languages=c,c++,objc --enable-threads=posix
--enable-__cxa_atexit
Thread model: posix
gcc version 4.0.3
in case that matters.
