Upgrade to ejabberd 2.1.5

During this night (CEST) we upgraded the Jabber server to ejabberd 2.1.5 – this time the Debian package came available very soon. :-)

Facebook transport for Facebook only

In the next days, weeks or months (it depends when the feature will be ready in Spectrum) we will implement white-/blacklists for our Facebook transport. After this the transport can only be used for Facebook – as it should be used. But as the Facebook transport is a “normal” XMPP transport many people use it for XMPP.

After the setup of white-/blacklists we will delete all non Facebook accounts out of the transport. Maybe we will move the non Facebook accounts to our XMPP/J2J transport, we’ll see.

So if you use our Facebook transport not for Facebook, please move to our XMPP/J2J transport.

BTW: Is there any need for a second XMPP transport as many of our users connect to more than one foreign XMPP account?

Upgrade to ejabberd 2.1.4

At about noon CEST today I just upgraded the server to ejabberd 2.1.4, which is a bugfixing release. Finally the Debian package is available. Sorry for the less than five minute short service downtime. ;-)

IRC transport migrated to Spectrum

We just migrated IRC transport to Spectrum. Before it was a core feature of ejabberd, the software we use for the Jabber server itself. Spectrum has more features, so we switched.

If you experience any problems please let us know.

DoS once again yesterday evening

Once again the server was hit. At around 8pm yesterday evening the services were unreachable for about 30 minutes, the transports for about 60 minutes.

For sure there will be another incident, but this time everything will get logged. From what we then read out of the logs we will choose how we react. If it has something to do with Nimbuzz, we will block Nimbuzz completely.

DoS attack again…

Again we suffered a DoS attack. The Jabber services and website were down from ~10:45pm to 00:30am.

For sure we have to do something about this. We are already digging into this, also recieving feedback from other Jabber server admins. Maybe abusive Nimbuzz accounts are the reason and, if this turns out to be true, we are also thinking about firewalling Nimbuzz.

What would you think about blocking Nimbuzz? Are you having friends from Nimbuzz in your roster? Tell us your opinion.

Pubsub/PEP migration to MySQL complete

…and it seems to work. Sorry for the 30 minute downtime because of that.

Planned Pubsub/PEP migration to MySQL

We are planning to migrate Pubsub/PEP (Publish-Subscribe / Personal Eventing Protocol) from Mnesia to MySQL in the very near future, which means the next two days.

Unfortunally there is no export/import script, so all data will be lost. It is also impossible to export own data from a client, at least I was told so.

Migration should fix some problems with PEP, also MySQL allows more administration and has less resource overhead.
