update:

I finally (after 48 hrs) managed to solve all issues.
this is the solution step by step:

# remove old libssl-dev (1.0) 
apt remove libssl-dev

# install openssl 1.10h from source
wget http://www.openssl.org/source/openssl-1.1.0h.tar.gz
tar -xvzf openssl-1.1.0h.tar.gz
cd openssl-1.1.0h/
./config && make && make install && ldconfig
openssl version -a #should report 1.1.0h now

# compile ncrack
/path/to/ncrack/configure && make && make install

Apparently during my process to fix the issue with ssllib I managed to mess the system structure; somehow removing ssllib-dev then installing openssl fixed the issue

this can be closed now

[ithilgore]

Please try compiling with openssl 1.1 and above. You are probably linking with an older version of openssl

[AddaxSoft]

sanity check: you mean libssl-dev 1.1?

[ithilgore]

Yes, but since your ubuntu version might not have 1.1 as a package, you can also try getting it directly from https://www.openssl.org/

[AddaxSoft]

I compiled and installed openssl 1.1, but

I'm getting this error on ./configure now:

checking OpenSSL header version... 1010006f (OpenSSL 1.1.0f  25 May 2017)
checking OpenSSL library version... not found
configure: error: OpenSSL library not found.
configure: error: ./configure failed for opensshlib

openssl version
OpenSSL 1.1.0f  25 May 2017

[ithilgore]

Did you also try uninstalling the libssl-dev package from previously to avoid any conflicts?

[ithilgore]

Also make sure that in /etc/ld.so.conf, there is a "/usr/local/lib" before the end of the file.
Then: sudo ldconfig

[AddaxSoft]

same error, hmmm do I have to rebuild and install openssl after I remove ssllib?

[ithilgore]

You can also try installing openssl using the --prefix /usr when you invoke ./config so that it's not at the /usr/local/ (might also need to change the --openssldir) See: https://github.com/openssl/openssl/blob/master/INSTALL

[ithilgore]

One more thing to try is when you run ./configure from Ncrack try specifying the openssl library location using --with-openssl=

[AddaxSoft]

wow I spent so much time on this and I still cannot get it right. I did compile openssl 1.1 and installed it but it doesn't recognize its own library.

On one box I have:

OpenSSL 1.1.0g  2 Nov 2017 **(Library: OpenSSL 1.1.0h  27 Mar 2018)**

ENGINESDIR: "/usr/lib/x86_64-linux-gnu/engines-1.1"

on the other where nrack fails I have:

What am I missing here? why is openssl not recognizing its own library making ncrack fail

[ithilgore]

Kali should be installing openssl 1.1 and above when you install libssl-dev - that is why it works there. The latest version of Ubuntu 18.14 also now installs openssl 1.1.g (https://packages.ubuntu.com/bionic/libssl-dev) when you install the libssl-dev package (and Ncrack compiles out of the box there without having to install openssl manually)

[AddaxSoft]

@denevin

but I'm not on kali, I'm on Ubuntu (see uname -a command outputs above)

[AddaxSoft]

after all the efforts I'm still getting the same issue.

my ldconfig -v reports ssllib1.1 being in the path of libs

/usr/local/lib:
        libssl.so.1.1 -> libssl.so.1.1
        libcrypto.so.1.1 -> libcrypto.so.1.1

openssl version -a reports the correct version, yet ncrack still fails to configure with error:

checking OpenSSL header version... 1010008f (OpenSSL 1.1.0h  27 Mar 2018)
checking OpenSSL library version... not found
configure: error: OpenSSL library not found.
configure: error: ./configure failed for opensshlib

[AddaxSoft]

half solution:

compile and install openssl 1.1 from source

wget http://www.openssl.org/source/openssl-1.1.0h.tar.gz
tar -xvzf openssl-1.1.0h.tar.gz
cd openssl-1.1.0h/
./config && make && make install && ldconfig
openssl version -a #should report 1.1h now

then go back to ncrack dir, and run make clean
after it's done run the following:

./configure --with-openssl=/usr/local
make && make install

now make fails at:

In file included from cipher.c:46:0:
cipher.h:69:17: error: field ‘evp’ has incomplete type
  EVP_CIPHER_CTX evp;
                 ^
Makefile:71: recipe for target 'cipher.o' failed
make[1]: *** [cipher.o] Error 1

[ithilgore]

There is no --with-ssl-dir switch in the configure of Ncrack. This will be ignored by the configure script. As I mentioned above the correct one is: --with-openssl. So try: ./configure --with-openssl=/usr/local

[AddaxSoft]

I updated my solution, but the script still fails now see #43

[AddaxSoft]

I'm back at square one now, the configure scriptt fails at

checking OpenSSL header version... 1010008f (OpenSSL 1.1.0h  27 Mar 2018)
checking OpenSSL library version... not found
configure: error: OpenSSL library not found.
configure: error: ./configure failed for opensshlib

I tried everything so far

• ldconfig trick
• reinstalling openssl 1.10h (default)
• adding --wth-openssl=/usr/dir

?????????

[ithilgore]

do a cat /etc/issue for me

I ll try to replicate it in the same ubuntu version and come back to you with the steps

[AddaxSoft]

Ubuntu 16.04.4 LTS \n \l (google cloud image)

I tried to do the same on another same ubuntu image and it worked same steps as I described in my 'half solution' (#42 (comment))

I'm not sure what did I mess up while doing this, because at some point I Got it working then it failed with #43 but now I'm back at square one.
