Hey, hello, happy Tuesday
Hope you're well, it's Tuesday again, so open evening at the hackspace.
We're in the throbbing heart of Bridge of Don south, at...
Suite H Kettock Lodge
Innovation Park
Campus Two
Bridge of Don
Aberdeen
AB22 8GU
...there is sort of useful blurb on...
https://www.57north.org.uk/open-evenings
...and...
https://www.57north.org.uk/contact
...just press buzzer H and someone will come and let you in after a brief
wait. Reply if you have any questions, if you want to share your plans, or
if you'd like a lift.
I'll be along around :30, will be doing some tinkering with PHP, pootling
about, and bits and bobs.
See you there :)
Hi All,
After taking a look at the Large Format Printer in the lab it will need at
minimum a Maintenance Cartridge. It is highly unlikely that any other parts
would be required as the print cartridge - if gunged up - can probably be
cleaned and made to work and we have additional ink cartridges if any of
the ink is unusable
LCL MC-10 Maintenance Cartridge ink Replacement for Canon MC-10 Replacement
for Canon imagePROGRAF iPF750, iPF755, iPF760, iPF765, iPF670, iPF680,
iPF685, iPF770, iPF780 (1Pack) : Amazon.co.uk: Computers & Accessories
<https://www.amazon.co.uk/LCL-MC-10-Maintenance-Replacement-imagePROGRAF/dp/…>
let me know your thoughts but I believe there is a high likelihood that
this would be the only required part
We have next meeting of python user group coming up on Wednesday with a talk + coding challenge on LLM delusions.

I go the extra mile.
Usually because I missed the turning I was supposed to take.
I’ll be in around 7:30 probably. Looking at server stuff. Maybe thinking about spacefed if things go well enough to move onto the next phase in the auth project.
If anyone is having issues accessing hub since the change I can help you get back in.
Iain.

Hi All,
tl;dr: The way you login to hub has changed. You'll get sent to "Keycloak" and will need to do a "Forgot password" and then reset your password via the emailed link. You shouldn't notice any difference after that other than the login screen is different.
If you go to log in to hub you will find that you get sent to a system called "Keycloak" instead of the former 57N ID. The old ID application served us well for many years, but had a dependency on a very unsupported and early version of node.js. Updating that code was going to require someone that knew not only modern node.js but also historic node.js to ensure the update was correct and complete.
Keycloak is a modern single-sign on system that implements protocols like OAuth2 and OIDC which means that we can integrate this with many of the existing space applications, like Home Assistant and the wiki. I have also configured it using an LDAP backend for user account and password information so we could use this for applications that only support LDAP authentication. We are lucky that someone has also provided a CAS plugin, as that's what Hub uses, and so no changes were needed to Hub at all other than re-pointing where it was looking for the CAS server.
I will be publishing the Ansible playbook used to deploy the system shortly under the BSD 2-clause licence. I'm also using it for my company and for one of my company's clients that runs digital security helpdesks. At some point it will probably get audited professionally.
The stack is built on a rootless podman setup, using quadlets to define the services. Network isolation is employed to prevent interncontainer connections between applications that do not need to communicate. The full stack includes:
• Nginx
• Certbot
• Keycloak
• 389ds (LDAP server)
• PostgreSQL (Relational database used by Keycloak)
Right now this is running on a Vultr VM while we continue to work towards retiring finzean. I believe the last service there is Hub which I think we can containerize and add to the podman setup. At that point we can migrate the whole stack to a replacement finzean.
The podman features we require only exist in Debian testing, and finzean currently runs Debian jessie, so we cannot do this upgrade in place.
You *can* enable 2FA to secure your Keycloak account but this is *not* required. We may later choose to require this for some or all of our applications but as this is something that needs documentation I don't think we should do it until we have that documentation.
If you have any questions then you can ask them and I might answer them.
Thanks,
Iain.

Hi all,
I need to make an RS order. If you want to get small things and not pay delivery then please let me know. You can get the stuff at space Tuesday.
Thanks,
Iain.

I'll be along around 7 ish, will be doing some mixture of looking at sewing

things around in a semi intelligible way.
See you there :)
Hi all,
I've been working on some improvements to my and my company's email security and this is a test mail to see if anything breaks when the mailing list tries to forward my mail on.
They've got crazy schemes like MTA-STS now where you need to publish DNS records *and* run a web server to host a policy file to tell other mail servers not to talk to you unless the connection is encrypted.
Mostly you can ignore this though.
Thanks,
Iain.

Hi
I'll be in around 7:30, probably be tinkering with web stuff and
complaining about bitbucket downtime.
See y'all then.
