Another week, another SSL/TLS security vulnerability. This one is termed Logjam (read about it here http://www.theregister.co.uk/2015/05/20/logjam_johns_hopkins_cryptoboffin_ids_next_branded_bug). Luckily a site has already been created to test your web servers, it is available at https://weakdh.org/sysadmin.html. A quick test of a Domino 9.0.1 server with the latest IF and the perfect forward secrecy server-side notes.ini settings enabled (see this previous blog post for those settings) y

I swear I voted for somewhere other than Atlanta.....no, really I did. Anyway, even thought it is technically called the Midwest User Group anyone can (and should) attend. So if you are in the Southeast you have no rational reason to not attend. If you use any of the IBM collaboration technologies this a conference you should have on your schedule. "But Darren, I can't get $1,500 approved to attend a conference". That's fine. It's only $50. Yes Fifty. I didn't miss off a zero. So now

Do you subscribe to the IBM daily product update newletter? Part deux - or why renaming your products sucks
Fri, Apr 10th 2015 11:00a   Darren Duke
A few years ago I wrote about how to subscribe to the daily IBM product update newsletter. A few days ago some one asks me if I still used this service. I thought I did, but on recollection I hadn't gotten an email from them in ages (or "yonks" for a more technical definition). At first I thought it was getting stuck in spam.....nope. Hummm. OK Let me log in a see.... I had no subscriptions listed. None. Nada. Ziltch. WTF? So I started adding in my subscriptions again and realized that

TLS 1.2 in Domino and the settings I use
Mon, Apr 6th 2015 8:20a   Darren Duke
Unless you have been living under a rock somewhere you no doubt know that IBM finally gave use TLS 1.2 for IBM Domino servers. This means that Domino servers can now use SSLv3, TLS 1.0 and TLS 1.2. But it's IT, so just because you can does not mean you should......for example I would suggest most servers (I'll get the outliers further down the page) would probably want SSLv3 disabled. If you have been under a rock, then you need Domino 9.0.1 FP3 IF2 to get this new goodness. Now this fix is

Domino and SSL ciphers. The server document may not be doing what we expect it to do
Tue, Feb 3rd 2015 8:52a   Darren Duke
While sat in Daniel Nashed and David Kern's excellent Domino Security session at Connect, there was a comment and slide that made me tweet this: Domino SSL ciphers set in the Domino Server document are ONLY applicable to HTTP. Not SMTP, LDAP, et al.... Doh. You can set with note.ini— Darren Duke (@darrenduke) January 27, 2015 Now, I'm back in the office it's time to address this. So based on that session it seems as if LDAP, SMTP, DIIOP, POP3 and IMAP (and Remote debug monit

ConnectED-sphere sudo review
Mon, Feb 2nd 2015 2:43p   Darren Duke
I was fully expecting to write a "what a train wreck" review before I went. I was not expecting to say I had a metric shit ton of fun. But I did. And based on other posts I've perused it seems almost everyone else did. There are far more eloquent reviews elsewhere, so this will be bare bones. First the "ups", in no particular order: Much, much improved OGS. Flow, demos, people who care.....And a quintet, who doesn't like quintets? It doesn't seem to matter how many people don't turn

Somehow I missed this, so I'm guessing some of you did too....New rules dated 10/16/2014. Thank you IBM. Woohoo! Indeed!!

If you are using my Reverse Proxy, please change the SSH host key
Wed, Jan 14th 2015 7:10a   Darren Duke
Well, technically this is for any Linux VM appliance you download, not just my reverse proxy.... Anyway, every Linux host should have it's own unique host SSH key to ensure security and authenticity of the server you are connecting to. When you create a server from an OVF that doesn't happen automatically. In fact you get the SSH host key that is on the OVA at time of creation (in this case mine).....potentially opening you up to man in the middle attacks (potentially.....although unlikely

Using IBM Lotus Traveler with a proxy....food for thought before you do this
Tue, Dec 16th 2014 6:11a   Darren Duke
Over that past few weeks I've been banging my head against the wall trying to figure out why a Traveler server that has been relocated behind a proxy would not work (it was a standalone server that was working fine before it was moved behind the proxy). Everything seemed fine, except one couldn't get to the Traveler log on page and/or add devices to the servers. Existing users worked flawlessly. Needless to say this was extremely aggravating. I'd install another, new Traveler server and put i

How to disable SSLv3 in Domino
Fri, Dec 12th 2014 6:01a   Darren Duke
In my POODLE TLS post from a few days back, there was a comment asking how to fully disabling SSLv3 in Domino. You'll notice in the comments I mention that there is a way but at the time it was under NDA. Well, apparently not anymore.... Now, fair warning this may not yet be supported by IBM so if you choose to do this, you do it at your own risk (while under NDA on this, it was stated that is unsupported so YMMV). According to this post on the Domino wiki, you can use this server notes
