RIP.</p> waxworlds.org http://www.waxworlds.org/news waxworlds.org http://www.waxworlds.org/news/feed/atom 2018-11-18T01:00:01+00:00 Decommissioning Jabber/XMPP http://www.waxworlds.org/news/2018-03-12 2018-03-12T00:00:01+00:00 <p>The XMPP (jabber) server is in a rather sorry state. It has not been operational since an upgrade at the end of last year broke it. The database needs to be upgraded to a new format, and neither the Debian package maintainers nor the upstream ejabberd project provide such a facility. I had always intended to manually migrate the data, but this now seems unlikely, give the constraints on my time.</p> <p>To that end, <strong>I plan to retire the waxworlds XMPP (Jabber) services on 12th June 2018.</strong></p> <p>We also now host a <a href="https://matrix.waxworlds.org/">matrix server</a> for chat. Matrix (and riot) have proved to be a very successful alternative to jabber that also works well on mobile platforms, handles multiple connections better, facilitates posting images/files/links and is generally much more modern in its approach to chat. Essentially, I would propose that he Jabber service is also now redundant and my recommendation, going forwards, would be to use matrix anyway.</p> <p>If there are any significant reasons why you think I shouldn't EOL the jabber service, or why you think I should attempt to manually migrate the data and revive it, please <a href="mailto:admin@waxworlds.org">get in touch</a> before 12th June.</p> waxworlds.org http://www.waxworlds.org/news waxworlds.org http://www.waxworlds.org/news/feed/atom 2018-11-18T01:00:01+00:00 New Oak SSH Host Keys http://www.waxworlds.org/news/2018-01-16 2018-01-16T00:00:01+00:00 <p>Oak has two new SSH host keys, which were generated today. So the next time you ssh to oak with a recent ssh client you will most likely get warnings that the host key has changed.</p> <p>The new host keys have the following SHA256 hashes:</p> <ul> <li><code>afl7rHgG55VCJNETep/aNZHzPnEssuWpEwx4JPrHr64</code> (ECDSA)</li> <li><code>nP2GP+gQ3AQNcbMzMpql9iy0MKP8e3guFUTCQNG0ci8</code> (ED25519)</li> </ul> waxworlds.org http://www.waxworlds.org/news waxworlds.org http://www.waxworlds.org/news/feed/atom 2018-11-18T01:00:01+00:00 Spamassassin http://www.waxworlds.org/news/2017-12-12 2017-12-12T00:00:01+00:00 <p>Apologies for any spam received over the past couple of days. Due to a power failure, <code>oak</code> was restarted and Spamassassin didn't come back up. It is now running again and the issue preventing it restarting is resolved. I will be monitoring it next time <code>oak</code> restarts.</p> waxworlds.org http://www.waxworlds.org/news waxworlds.org http://www.waxworlds.org/news/feed/atom 2018-11-18T01:00:01+00:00 Procmail fixed http://www.waxworlds.org/news/2017-10-28 2017-10-28T01:00:01+00:00 <p>There was an issue on <code>mail.waxworlds.org</code> that was preventing <code>procmail</code> from running. This is now fixed.</p> <p>Procmail is probably configured, amongst other things, to send your mail to SpamAssassin to be checked. So appologies to those of you who were receiving more spam.</p> waxworlds.org http://www.waxworlds.org/news waxworlds.org http://www.waxworlds.org/news/feed/atom 2018-11-18T01:00:01+00:00 Scheduled maintenance http://www.waxworlds.org/news/2017-10-22 2017-10-22T01:00:01+00:00 <p><code>oak.waxworlds.org</code> will be down for approximately 30 minutes on the evening of Tuesday 24th October somewhere between 7pm and 11pm whilst work is carried out on electrical systems.</p> <p>This will briefly affect mail.</p> <p><strong>Update:</strong> oak is now down...

Two-factor authentication is only used alongside password authentication.</p> <p>ol { list-style-type: lower-alpha; }</p> <p>Users wanting to be able to SSH in with a password will need to <em>either</em></p> <ol> <li><p>contact me, and I will set up a secret key for your account, <em>or</em></p></li> <li><p>run <code>google-authenticator</code> from the command line on <code>oak</code> to set it up for themselves. The command will generate your secret key, ask you a few questions and then save a local <code>~/.google_authenticator</code> configuration file.</p></li> </ol> <p>You will probably want to install the <a href="https://f-droid.org/packages/com.google.android.apps.authenticator2/">Google Authenticator app</a> on your phone/tablet/watch (it is free/libre and open source and available on F-Droid). There are also several other FOSS OTP authenticator apps that are compatible.</p> waxworlds.org http://www.waxworlds.org/news waxworlds.org http://www.waxworlds.org/news/feed/atom 2018-11-18T01:00:01+00:00 Server update http://www.waxworlds.org/news/2017-07-31 2017-07-31T01:00:01+00:00 <p><code>oak</code> and <code>ash</code> have both been updated to latest stable version of Debian (stretch). This should mark a big improvement over the software that was running on them, which was becoming quite dated.</p> <p>As a result, several services have been affected by the update and have required some maintenance. These are:</p> <ul> <li>Web services</li> <li>MySQL</li> <li>Matrix</li> <li>mail (and spam filtering)</li> <li>SSH</li> <li>XMPP (jabber)</li> </ul> <p>Outstanding issues are:</p> <ul> <li><strong>The XMPP server is down and will require some work to fix.</strong></li> </ul> <p>I will update below as and when problems are resolved. If you notice anything awry, please let me know immediately.</p> <hr /> <p><strong>UPDATE:</strong> Web services are working again (they were only down briefly) [2017-07-31]</p> <p><strong>UPDATE:</strong> MySQL has been migrated to Maria and there was briefly an authentication, which has been resolved. [2017-07-31]</p> <p><strong>UPDATE:</strong> The Matrix server is now working again. [2017-07-31]</p> <p><strong>UPDATE:</strong> Mail is working again and should start to come through. No mail should have been lost. [2016-07-31]</p> <p><strong>UPDATE:</strong> The issue with SSH keys has been resolved.

I have not yet had a chance to make a propper analyisys of the problem, but it looks as though the disk might be toast and a complete reinstall might be on the cards.</p> <p>The upshot of the situation is that mail, jabber and access to the Central network are unavailable until I am able to resolve the problm.</p> <p>I will update here as things unfolds or when I find out more.</p> <p><strong>Update:</strong> <code>oak</code> has been up and running this evening and has been catching up with mail.
