Based on the date displayed by your version of OpenSSL, it seems you are seeing the full version displayed there.
Open SSL 1.0.1 was released on March 14th, 2012. 1.0.1a was released on April 19th of 2012.
So, I'm going to go ahead and assert that openssl version -a
is the proper, cross-distro way to display the full version of OpenSSL that's installed on the system. It seems to work for all the Linux distros I have access to, and is the method suggested in the help.ubuntu.com OpenSSL documentation, as well. Ubuntu LTS 12.04 shipped with vanilla OpenSSL v1.0.1, which is the version that looks like an abbreviated version, on account of not having a letter following it.
Having said that, it appears that there is a major bug in Ubuntu (or how they package OpenSSL), in that openssl version -a
continues to return the original 1.0.1 version from March 14, 2012, regardless of whether or not OpenSSL has been upgraded to any of the newer versions. And, as with most things when it rains, it pours.
Ubuntu is not the only major distro in the habit of backporting updates into OpenSSL (or other packages), rater than relying on the upstream updates and version numbering that everyone recognizes. In the case of OpenSSL, where the letter version numbers represent only bug fix and security updates, this seems nearly incomprehensible, but I have been informed that this may be because of the FIPS-validated plugin major Linux distros ship packaged with OpenSSL. Because of requirements around revalidation that trigger due to any change, even changes that plug security holes, it is version-locked.
For example, on Debian, the fixed version displays a version number of 1.0.1e-2+deb7u5
instead of the upstream version of 1.0.1g
.
As a result, at this time, there is no reliable, portable way to check SSL versions across Linux distributions, because they all use their own backported patches and updates with different version numbering schemes. You will have to look up the fixed version number for each different distribution of Linux you run, and check the installed OpenSSL version against that distribution's specific version numbering to determine if your servers are running a vulnerable version or not.
Replace "!3DES" with "-3DES" and add your 3DES cipher suite ID afterwards
You've got this base string:
$ openssl ciphers -V 'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!3DES:!MD5:!PSK' | nl
And on my OpenSSL 1.0.2d 9 Jul 2015
this leads to these 22 cipher suites:

You can explicitly throw cipher suites out of your resultant set in two ways:
- by prefixing the ID with
!
- by prefixing the ID with
-
Once you've used !
to throw out a cipher suite set you can not re-add them. This is what you did with !3DES
.
Here's a set that contains the additional suite you wanted:
I've replaced the end of the cipher string from
:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!3DES:!MD5:!PSK'
with
:-3DES:EDH-DSS-DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK'
This now gives 23 cipher suites:

If I'm understanding your question correctly, you wish to disable TLSv1 at compile time, so openssl won't support the protocol. If that's what you are after, there are two flags that apply, and this is the official description:
You should pay attention to the final note on the no-tls flag, which states that it only affects the negotiation.
