A note on Security

I have recently received questions wether Karchan is secure, depending on behaviour that people see in their browsers. Well, truth of the matter is of course that I can never be 100% certain.

I do try very hard to increase the level of security of the game at every opportunity. It already has been strengthened considerably since the days of Drupal.

That said, I felt the need to write a permanent page and add it to the website, to detail how you can play the game in relative safety.

You can find the page here and it is also accessible from the Help menu. Choose Security.

High regards,

Entering the game has changed

Fell, I did mention that I would put up a blog post indicating the recent changes.

For those who have not noticed, logging into the game has changed.

The new process is as follows:

  1. log on
  2. enter game
  3. play game
  4. quit game
  5. log off

I am very happy with the change. No longer is the security part something that I cooked up myself, but instead we're using the Glassfish security realms.

It is no longer required to play the game, when you log on. But once you have logged on, playing the game is as simple as the press of a button.

Also, as you now see there is some content in the "Settings" page. This page will be expanded with the possibility to edit your charactersheet and/or guild etc. So, though it seems very empty for now, this will change.

A small but important note on security

I use SHA-1 hash to encrypt passwords. I've decided to move over to SHA-512 hash as being more secure. As I don't know peoples passwords, I've rigged the software to re-encrypt the password when somebody logs in.

It does mean that it is very important for you to logon at least once with each one of your characters.

Once the change becomes permanent, your characters with the old encrypted passwords will become inaccessible without deputy intervention.

Maintenance complete

aintenance is now done. Let me know if I screwed up somewhere along the way.

I will write a blog about the changes, though they should be fairly obvious and unambiguous, but I'll add some backstory about why.

Also, chances are that if things do not work, you might want to refresh the page, or reload the page, or clear your browser cache, or some of that jazz.

Seriously, clear your browser cache.

Regards,

he game is currently under maintenance.

 

The Wiki!

owdie, peoples.

As you may have noticed, the Land of Karchan website is currently housing a Wiki. The Wiki is under active development and you can contribute as well! In order to do your part, you have to register on the Land of Karchan website using the blue thing on the upper-right corner of the browser. The website is open for everyone. Verification takes place using your email address.

Just to make sure you understand, if successfull you then have two accounts. One for playing the game, and one for fiddling with the website wiki. These two accounts have absolutely nothing in common with each other.

Also bear in mind the following:
- Liferay is a multi-site system, meaning just registering is not enough to be able to do something with the wiki.

The following steps also need to be undertaken:
- Once registered and logged in, click on your name in the tab on the upper-right corner of the browser
- Select Dashboard from the dropdown list.
- Under "My sites" you will see that you are not a member of *any* sites. 
- Under "Available sites" there is just one option: "Karchan".
- Click on the "Join" next to Karchan
- Done.

You should be able to edit the Wiki, when you select it in the menu bar.

Not done!

Things are not done yet. Working.

Maintenance rescheduled until a later time.

Regards,

System Down for Maintenance Tonight

People of Karchan,

I plan on getting that logging and security thing I mentioned previously done today and releasing it this evening, 22:00 game time.

It will probably make it impossible to log in for some time and play the game.

Server Maintenance Done

ell, the server has a lot more room now to expand, so I am expecting less of the "oh noes, the game has crashed with an out of memory error!".

I did not get around to updating logging into the game, as it requires a bit more research and testing.

So, the game is back and available, if anyone's interested.

Scheduled Server Maintenance

The server requires some maintenance. I am planning on upgrading the server to more memory/diskspace/fatter pipes and stuff. It sems what with jenkins, liferay and glassfish, the current server specifications are a tad lacking in punch.

I am also planning on updating logging into the game, for security reasons.

Server maintenance is for now scheduled for Sunday, 22:00 game time. It is currently unknown how long this will take, but I will try and have the game up again as soon as possible.

Theme fixed

I've added the theme again, under a different name.

Seems to work for now.

Of course, as always, mention it when it screws up again.

Sorry about the downtime today

I am still new at this whole Liferay thing, and for some reason I am having severe problems getting the karchan theme to get inserted into Liferay properly.

I have made a workaround for now, by adding the javascript libraries directly to the webpage entries instead of in the karchan theme.

The karchan theme is not picked up, at the moment, so it defaults to classic, which does not help.

You should be able to access the game normally.

Let me know if anything is amiss.

Merry Christmas to All and to All A Good Night...

ello, People of Karchan,

Well, it has been a very interesting year and no mistake and I thank Karn that Karchan is still here.

May it continue to be, and be a place for you to hang out with everyone for many years to come.

Christmas treeTo you all a Merry Christmas, and a Happy New Year.Holly

 

Karchan was Under Attack

esterday, I got an email from my Service Provider that my server was targetted specifically in a DDoS attack. To prevent it from effecting their other customers, all traffic to the server was (temporarily) blocked.

Now, things seem to have normalized again, slightly.

I did some checking and there have been a huge number of attempted logins into the server (not in the game, but to the server itself) from a wide variety of ip addresses. In fact, those attempts are still ongoing, about every few seconds.

To the best of my knowledge, since the new install and the change of software stack, the attempts have all failed.

This might be a last desperate effort from the people who inserted the Advertising IFrame when my server was still vulnerable, but who knows?

Regards,

Karchan Down

his morning, at about 01:58, Karchan went down. To be more specific, Glassfish, the application server, went down as it was short of Memory.

I have since restarted it, and provided it with an additional 400 megabytes of memory. It should run smoothly again.

However, there is a chance that there is a memory leak somewhere, slowly claiming all memory. When that happens, we will see the same behaviour.

Let me know when it does. I'll see about checking out where the memory leak is.

Regards,

 

Encryption

o anyone who is even vaguely interested in encryption and security and all that, the term HTTPS should have a familiar ring.

HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet.

As of now, the Land of Karchan can be accessed using two site urls:

http://www.karchan.org

and

https://www.karchan.org

The last link is encrypted. Both site urls lead to the same game, so you can decide for yourself what you wish to use.

Regards,

We're back,... sort of.

It is now once again possible to login and play the game and when finished log out.

This is all that currently works. I am still hard at work fixing all the other stuff.

The Big Talk function doesn't work as yet, because I haven't added the tinyMCE yet. All the other buttons seem to work as designed.

Let me know if there is anything that seems wonky (and I am sure there will be plenty of that!)

Regards,

Game will be online today!

Time for an update!

I am still working around the clock, and I am currently focussing the most on getting the game running again, that we can actually play.

I expect to have something running not much later today.

Regards,

Land of Karchan Hacked!

Well, for those of you who haven't noticed yet, recently the website Land of Karchan had been hacked.

As I am unable to determine quite in which way the intruders gained entry (and changed files, as far as I know only on the website part) I decided to clean the server and install from scratch.

Therefore, as for now, there is no Land of Karchan to be played.

Rest assured, I am working as hard as I can to get things back into shape.

Regards,
