A couple of weeks ago in my NSX-v and NSX-T release post I focused around NSX-v features as that has become the mainstream.

Configure Rancher
Make sure you disable the pop-up blocker for your Rancher domain and whitelist it in any other extensions you might utilize. Additionally, hovering over your user icon on the top-right should yield your name and your Okta username. Technically you are done! Rancher will only know about groups you are a part of the ones it received from your SAML assertion , which is unfortunately somewhat limiting.
By default, your SAML users will receive no access to anything at all. Now your users can see the cluster, but none of the Projects or pods inside. Time to repeat this process by authorizing a group to a particular project:. My employer wholly embraces the coffee-shop model for employee access, which can induce a bit of stress if your job is to protect company resources. Historically, we have had to support some applications that:.
Yet, employees were frustrated that most day-to-day operations did not require jumping on a corporate VPN until you had to reach one of these magical systems. The following examples assume Ubuntu Our ModSecurity install will do one thing and one thing only: Go to your identity provider and provision the new application. In your vhost config in the Mellon options, add:. In your application, simply check for a value in this header and use it if present.
Some applications, like Splunk , can receive login user information via request header note: Splunk now supports SAML natively , but it still makes for a good example app.

Be careful to make sure your back-end application is only accessible via this reverse-proxy though, otherwise someone with local network access could simply send the back-end server requests directly with this header to bypass authentication entirely 2. Because it addresses several other pain points, we are actively working to deploy ScaleFT at my organization, which will likely replace the home-grown solution described in this post. Do your part to prevent data breaches by seeking assistance from someone with relevant security experience if you are unsure whether or not your back-end application on another host is properly protected from such an attack.
The Heartbleed issue is actually worse than it might immediately seem and it seems pretty bad already. The major concern is that a skilled user could craft an exploit that could dump the RSA private key that the server is using to communicate with its clients.

So why is Heartbleed worse than you think? As of this morning, the most widely-shared proof-of-concept is this simple Python script: With this script, anyone in the world can dump a bit of RAM from a vulnerable server. The hex output has been removed to improve readability.
This is definitely a dump of memory from a GET request that came in very recently. The only way to detect this type of attack is to check the source IPs of traffic for each and every request.
Valuable Software
The Heartbleed vulnerability is bad, and with almost no effort allows a remote attacker to potentially perform a session hijacking attack allowing authentication bypass. Please patch your systems immediately.
Configure Okta or some other IdP The rest of these instructions will be Okta-specific, but the concepts are not. Occasionally, two mappers get one number. Sometimes, an emulator can distinguish them easily: But other mappers are messier: This of course fails if the game is not in the database, especially newly developed homebrew games.
In the early days of iNES, 16 mappers seemed like it would be enough, but they were quickly exhausted. Then mappers seemed like a vast space to work on.

But now, we are getting near the end of the line, and running out of mapper numbers. Horton alone has assigned at least 50 or 60 of them, which is almost a quarter of the total mapper space.

This last one was a very recent find at the time NES 2. Submappers are used to disambiguate iNES 1 mappers that require multiple incompatible implementations. Most mappers will not use submappers; they set S to 0. It's not recommended yet as of to assign mapper numbers greater than There were still a couple dozen existing numbers left in the current iNES mapper space as of Mapper numbers up to should hold us until they stop making Ice Age films; mapper numbers up to should hold us until the next literal ice age.
In , there was a proposal on the BBS to break up the expanded mapper space into "planes", much like those of Unicode when it expanded past UCS Each M value would thus correspond to one plane:.
VIRTUALIZATION IS LIFE!
Bytes 10 and 11 of the header define the size of the RAM segments exponentially using 4-bit values:. The vast majority of mappers fall into one of the first two categories above. In most cases, the battery backed PRG-RAM field can be used as a guide for how much information an emulator must save, but many of the special cases have other requirements that conflict with this, so this field is not universally reliable for that purpose. For backward compatibility, the battery bit in the original iNES header byte 6, bit 1 MUST be true if the upper nibble of byte 10 or 11 is nonzero or false otherwise.
