Today we are going to create static.exe binaries fornetcat.

While there are manyports and reimplementations of netcat, we are going to stick withwin32 ports fornetcat 1.11 ornetcat 1.12 (the latter one enables sendingCRLF line endings instead ofCR using command line option-c).

We will useMXE as our cross-compilation environment. Compile thecc package as described in thetutorial. Add the directory with cross-compilers to yourPATH.

Then download and unpack the source from thewin32 ports above and issue the following commands:

i686-w64-mingw32.static-gcc -DNDEBUG -DWIN32 -D_CONSOLE -DTELNET -DGAPING_SECURITY_HOLE getopt.c doexec.c netcat.c -O2 -s -static -lkernel32 -luser32 -lwsock32 -lwinmm -o nc.exe

and

x86_64-w64-mingw32.static-gcc -DNDEBUG -DWIN32 -D_CONSOLE -DTELNET -DGAPING_SECURITY_HOLE getopt.c doexec.c netcat.c -O2 -s -static -lkernel32 -luser32 -lwsock32 -lwinmm -o nc64.exe

to compile the 32-bit and 64-bit version respectively.

I compiled netcat 1.12 for you and placed it into aDropbox folder.

If you decide to use them, here are the MD5 checksums:
