Outage (equipment fault)

Our internet provider has confirmed that there is an equipment fault at their end which is causing an outage of oak.waxworlds.org. An engineer has already been scheduled to address and resolve the issue but he will not be on-site until Monday 16th December. Until then, oak will be down, I'm afraid.

Effect

Since oak has been partially migrated in to the cloud, web, DNS and chat services are unaffected. The major service affected by this is email. We shouldn't lose any mail -- SMTP replays hang on to it and retry delivery when it fails -- but I'm also going to look in to whether or not I can migrating mail to the cloud immediately.

Updates

  • (2019-12-15) There seems to be intermittent line sync and some mail is getting through.

  • (2019-12-16 1:32pm) Fault is fixed. We're back up!

Oak moving to the cloud

Over the next couple of weeks I will be migrating the user accounts and network services that currently run on oak to a new cloud-based server.

This includes:

  • email
  • matrix
  • user accounts

Jabber/XMPP decommissioned

As discussed, the jabber service is now EOL. RIP.

Decommissioning Jabber/XMPP

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.

To that end, I plan to retire the waxworlds XMPP (Jabber) services on 12th June 2018.

We also now host a matrix server 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.

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 get in touch before 12th June.

New Oak SSH Host Keys

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.

The new host keys have the following SHA256 hashes:

  • afl7rHgG55VCJNETep/aNZHzPnEssuWpEwx4JPrHr64 (ECDSA)
  • nP2GP+gQ3AQNcbMzMpql9iy0MKP8e3guFUTCQNG0ci8 (ED25519)

Spamassassin

Apologies for any spam received over the past couple of days. Due to a power failure, oak 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 oak restarts.

Procmail fixed

There was an issue on mail.waxworlds.org that was preventing procmail from running. This is now fixed.

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.
