Status update on mod_mam

Hello users!

Last night I performed maintenance to disable mod_mam archives by default (along with the few other things).

This means that messages are not archived by default on the server, and are only archived if your XMPP client specifies that they should be. The MAM module has one major flaw right now. It cannot purge archives fast enough. It seems to get stuck and it kept the messages for much longer than it was supposed to. Due to this, during the maintenance I have purged all MAM archives from the server. Security, privacy and transparency are all my number one priorities when it comes to the server. When I enabled MAM on the server I had to consider the benefits vs the trade-offs. I believe we’ll be better off with MAM disabled by default, because a lot of clients don’t even support it yet.

If you can have any questions, feel free to reach out!

New Years Announcement

Hello users!

I haven’t made a post in a while, so I figured I’d make one about what’s going on with XMPP.is. First of all, Happy New Year! 2018 has been a great year for the server and I’ve received $135 USD in donations via PayPal. Thank you to all the donors, you are what helps keep this server running. Thank you to the few who donated cryptocurrency as well! Since there hasn’t been many posts, here are some things I’ve accomplished last year…

  • I made numerous improvements to the server’s configuration, adding support for many new XEPs and becoming 100% compliant according to this compliance tester. I’ve made several improvements to the server’s scripts and even added a few. You can see every change I’ve made on GitHub. Open source is the best 🙂
  • I’ve updated a lot of pages on the site, adding more info and descriptions.
  • I’ve tried to keep downtime to a bare-minimum. With the new hypervisor things have been more stable than ever. I’ve also improved on scheduling maintenance windows and giving notice beforehand.

Now onto 2019…

Recently I’ve been working on cleaning up registered users. We currently have over 37,000 registered users. Many years ago before I had web registrations and captchas in place, a nefarious individual/group registered over 35,000 accounts en-masse. A lot of the accounts follow a pattern (which I won’t disclose). I am working on cleaning up these users and deleting them, as they’ve never been used (as far as I know). This is a long and drawn out process as I have to make sure the accounts I’m deleting are not legitimate.

I’ve made a couple one-liner scripts in bash to find these accounts based on the pattern in their usernames that I’ve noticed. While it work 95% of the time, it also picks up legitimate users and I have to manually filter them out from the deletion lists. I’ve been going through the lists when I make them and taking out any users that look legitimate. As this is a manual process I might miss a few here and there… If your account gets deleted and you notice you can no longer login, please let me know. I can restore it from encrypted, off-site backups. Keep in mind that these usernames are very uncommon. They are probably taken from a word list and random numbers are added to them.

If you have any questions, feel free to reach out!

2018 Status Update

Hello users!

A little late… but Happy New Year!

I wanted to post about some recent changes that XMPP.is underwent this past few months.

  • mod_cloud_notify (XEP-0357: Push Notifications) support has been added. twitter.com/xmpp_is/status/946592338607996928
  • The security page has been updated with more details about how we care for your data.
  • Non-standard ASCII characters in usernames are no longer allowed when registering. People could potentially impersonate other users for malicious purposes. See: twitter.com/xmpp_is/status/954729573173940224
  • We now have a fair (in my opinion) TOS/AUP.
  • The 2018 donation goal has been created. I lowered it this year to cover at least domain costs, and a little more. Thank you to all that donated USD and crypto-currency!
  • The donation page has been updated with our hard-coded crypto-currency wallet addresses. If you’d like to donate with any of those, please opt for the ones we provide (more privacy).

Offline Messages Are Back!

Hello users!

Offline messages are now back after a short maintenance window yesterday. After speaking with a user that thought offline messages are very important, and much needed for instant messaging services.. I fully agreed and decided to enable the module again after the attack we underwent a few months ago. Despite the shortcomings of the offline messages module in Prosody, I believe this to be important. Previously, if you were offline, even for a short period of time, messages could be lost. This would obviously be annoying, as pretty much any modern IM service will just store messages server-side until the user is online. So.. In the meantime hopefully things hold up. In the meantime I will have systems constantly monitor everything server-side to alert me of any potential issues.

In other news.. I’ve patched Tor packages on the server due to the recent CVE‘s. I’m also continuing to research new modules (been busy) that I can add to support more XEPs. The following are on my list for testing:

Status Update

Hello users!

Just wanted to write up a little update, the stability of XMPP.is has been in question recently. 🙁

After a long and strenuous attack it appears that everything is stable now. We’re back on the main dedicated hypervisor. I made a lot of configuration tweaks, and wrote several scripts to make stability a priority and migration easy while the attack was going on. All configuration and scripts are now hosted on GitHub, which I use to pull changes from. If you have a suggestion or would like to contribute feel free to! Everything is open.

In other news:

  • The donation goal has been updated to a ‘yearly’ cycle. I’ve also updated the operating costs page which now more accurately reflects what it costs to run the service. Cryptocurrency donations are subtracted from the goal.
  • I made a new script that outputs the current certificate fingerprints for all of the domains, which you can find on the transparency page.
  • I’m currently testing a password reset module that allows you to reset your password with the email set in your vCard. Source here.
