Hello,

I have been attempting to compile dsniff-2.3 on a Slackware 8.1 system. Unfortunately, "make" dies with the following error:

-----------------------------------------------------------------------------------
gcc -g -O2 -D_BSD_SOURCE -D_BSD_SOURCE -D__BSD_SOURCE -D__FAVOR_BSD -DHAVE_NET_ETHERNET_H -DLIBNET_LIL_ENDIAN -DDSNIFF_LIBDIR=\"/usr/lib/\" -I. -I/usr/include -I/usr/include -I/usr/include -I/usr/include -I/usr/include -I/usr/X11R6/include -I./missing -c ./arpspoof.c

./arpspoof.c: In function `main':
./arpspoof.c:181: warning: assignment makes pointer from integer without a cast
make: *** [arpspoof.o] Error 1
-----------------------------------------------------------------------------------

(To clarify, I used "configure --prefix=/usr")
I have been googling for a solution, but haven't found anything. There
are similar errors (all beginning with u_int32_t declaration problems) with
most of the programs included in the dsniff package.

TIA,

What I don't understand is why it's breaking,
since there are only warnings ...

I went searching and noticed that the current version of libnet (the 1.1.x series) does not define "ETH_H". So I removed the new version and installed the 1.0.2a release (the obsolete, unsupported version according to the website). Now I can at least compile most of the programs, but for the rest the linker complains that it can't find "libnet_init" and "libnet_write". Perhaps it is expecting an even older version of libnet?

For now I'm going to try the beta 2.4b1 beta of dnsiff.
