Purge of inactive users

Roi — Wed, 21 Sep 2011 06:14:22 +0000

The deletion of inactive users from the Jabber server and all Spectrum based transports will take today or tomorrow.

We will delete all users who did not login one year or longer. Also we will delete all users who did not login after the creation of their accounts. This could also affect users who did register less than a year ago. So if you registered and did not login since then you have to reregister again.

Again, we have an exclude list. If you want to have your account on the exclude list, contact us and tell us why.

Inactive users statistics

Roi — Wed, 14 Sep 2011 06:45:17 +0000

To show why we will clear up the databases here some statistics:

We just picked out the big players on our server for this blog article.

The first number are total users, the second number are the users, who did not login within the last 365 days.

jabber.hot-chilli.net: 20130 / 11480 (4116 of these users never logged in)
aim.jabber.hot-chilli.net: 1379 / 875
facebook.jabber.hot-chilli.net: 1729 / 46
icq.jabber.hot-chilli.net: 4051 / 1930
j2j.jabber.hot-chilli.net: 12903 / 10317
msn.jabber.hot-chilli.net: 9652 / 3330
yahoo.jabber.hot-chilli.net: 4548 / 2097

The only service with mostly active users seems to be the Facebook Transport.

Clearing up inactive users

Roi — Wed, 14 Sep 2011 06:29:50 +0000

In the next days we will implement script to delete inactive users from our databases (Jabber server and Transport services). Most users in our databases are inactive so we want to get rid of them. This reduces the overhead and leads to better usage statistics. Also it is freeing up usernames which can be registered again by new users.

There will be an exclude list. If you think your username should be on the exclude list, please get in touch with us and tell us why.

As soon as the deletion jobs are ready to run the first time we will announce this about a day in advance.

Nimbuzz blocked

Roi — Tue, 13 Sep 2011 22:36:03 +0000

We just blocked Nimbuzz traffic via our iptables firewall. At the moment this is just a test, but maybe we will block Nimbuzz for good.

The system has way too much CPU and memory usage and is not running stable. We have to do something about it. If it means that we have to block out Nimbuzz as there is no other way, then it is has to be the solution.

Server flatlined third day in a row

Roi — Sun, 11 Sep 2011 08:43:29 +0000

At the moment we don’t have any idea why. As I am in Italy right now I will investigate this after my return home in the middle of the week. Please stay tuned.

Is anybody aware of any current exploits for ejabberd?

Stay up to date with Twitter @hotchillijabber

Captcha activated for account registration

Roi — Thu, 24 Mar 2011 22:35:36 +0000

One of the main reasons we were really looking forward for ejabberd 2.1.6 is the support of captcha for mod_register. This module handles in-band registration, which means the interface where users can register through their client. This interface is also abused by spammers. We hope that the use of captchas will prevent most spam registrations.

If you client does not support captcha you well see a url where you can see the captcha in your browser window.

Upgrade to ejabberd 2.1.6

Roi — Thu, 24 Mar 2011 21:51:47 +0000

Finally the Debian package for ejabberd 2.1.6 is available. Therefore we will perform an upgrade to ejabberd 2.1.6 in the next minutes. There will be a short service outage.

Remote roster feature renames buddies in Jabber roster

Roi — Thu, 17 Mar 2011 23:46:39 +0000

We noticed that buddies in Jabber roster are now renamed into the original names from the legacy networks, e.g. ICQ or Facebook.

This affects just local transport users as remote roster only works on the same server.

Sorry about that… But now the rosters are synced and renaming the contacts will also rename the contacts in the legacy network roster. If renaming in the legacy network is not supported the databases of Jabber and the transport service are synced anyway.

ICQ transport problems

Roi — Thu, 17 Mar 2011 21:18:33 +0000

We experienced problems with ICQ transport the last days. According to the developers of Spectrum this is a “glib poll” issue. epoll unfortunally does not work with glib (yet).

Therefore Spectrum ICQ transport now uses libev3 and epoll.

It looks good at the moment, I hope it stays that way. We will see what happens during the next days as our server is the only server which runs this configuration. Not even the Spectrum developers were able to test it, yet.

Remote roster

Roi — Thu, 17 Mar 2011 21:09:17 +0000

We just restarted the server to activate Remote roster. What is that?

What’s Remote roster?

Remote roster is protoXEP which allows your server to synchronize legacy network contact list with your users’ rosters. Currently it works only for local users (users registered on the same server which supports this protoXEP). It’s available for Ejabberd 2.1.x and Prosody.

Why should I use it?

It allows to your users following features:

When they register their account and login for first time, they won’t receive lots of subscribe presences or Roster Item Exchanged stanza. All their legacy network buddies just appear in their roster with proper groups and nicknames.

When they will unregistering their account, buddies are just removed from their rosters without need of unsubscribing them.

When they rename some buddy in their Jabber roster, it’s renamed also in legacy network.

When they move some buddy into different groups, it’s moved also in legacy network.

All changes made in legacy network when transport is disconnected are synchronized with Jabber account once they become online in Jabber.

Taken from Spectrum website.

Numerous crashes…

Roi — Thu, 25 Nov 2010 00:41:08 +0000

…happened the last days. This occured out of nothing. Same symptomatic like some time ago when the Jabber server thread suddenly took all available resources and killed the server itself.

We digged deep into the problem and hope, we found a solution for it – which we implemented about one hour ago. A short service outage took place because of a restart to activate the setting.

Hopefully we got to the problem.

New transport service: Identi.ca

Roi — Sat, 16 Oct 2010 20:27:17 +0000

Since today there is a new transport online: Identi.ca

The JID is identica.jabber.hot-chilli.net.

Have fun with it!

Facebook & second XMPP transport

Roi — Sat, 16 Oct 2010 20:16:53 +0000

Sorry for posting just now. Facebook transport was blocked for Facebook use only on the day we posted about it, which means October 6th. We did not delete the old contacts for local users, as the user should get unsubscribe messages as all other users. If you still have old users in your roster, please delete these entries manually.

The second XMPP transport is online since since October 6th as promised.

Second XMPP transport and Facebook transport for Facebook use only

Roi — Tue, 05 Oct 2010 23:19:53 +0000

As mentioned here we finally have the feature which allows us to limit our Facebook transport for Facebook use only. We will delete all non Facebook accounts from the Facebook transport later today. You will be able to recreate these accounts on our second and new XMPP transport called xmpp.jabber.hot-chilli.net. We created this second XMPP transport because we noticed that more than one XMPP transport seems to be important for many people.

If you used Facebook transport for general XMPP usage and are a local hot-chilli Jabber user we delete all old contacts containing @facebook.jabber.hot-chilli.net in your roster for you. If you are a non-local user you might have to do this by yourself – which means that you have to delete all contacts containing @facebook.jabber.hot-chilli.net. When unregistering the accounts Spectrum sends unsubscribe notices to the Jabber servers, local and non-local. But all of you (local and non-local users) have to delete any leftover and obsolete contacts which might be left in your roster and/or the Jabber client.

We will announce when we finished the chances on the server here in the blog.

To activate the second XMPP transport the Jabber server will be restarted at 5:50 CEST today.

DoS again?

Roi — Tue, 28 Sep 2010 18:52:46 +0000

Are we under attack again? It seems – because the server went down yesterday and today. Sorry for the outage, we are looking into the logs as I write this post. Maybe we can find something…

IPv6 reconfiguration

Roi — Fri, 24 Sep 2010 10:27:02 +0000

Since our provider now supports native IPv6 (including reverse DNS) we changed our IPv6 configuration and now no longer use an IPv6 Tunnel Broker. Therefore we had two short service outages today to reboot the machine and activate the new settings.

If you are using IPv6 you might have to flush your DNS (or wait up to 24 hours from now) to get the correct IPs back from DNS.

Jabber service outage

Roi — Mon, 16 Aug 2010 06:53:50 +0000

There was an outage of our Jabber services the last hours. Unfortunally the hard disk ran completly full because of a faultly backup job.

Everything is back online. Sorry guys!
