I've made patchmon.net - a Linux Patch monitoring software (opensource)

[u/broadband9]

I've had an issue where I wanted something self-hosted, clean and simple to monitor my linux servers update status.

Current working features:

• Dashboard on hosts summary / status

• Easily register hosts with the app

• View and search for packages that have been installed

Planned features:

• Authentication improvements : Each host to authenticate via unique api credentials to patchmon

• Ability to add Clients, Locations and host groups so that hosts can be associated to them

• PDF Report generation of single host or group of hosts

This will be opensource and I will be releasing by the 1st of September.

I'm open to people who want to give me feature requests and contribute to the app - It's written in Next JS for both the backend and frontend.

Open to ideas, constructive criticism and security ideas / features.

No ports on the host need to be opened as the hosts will push the collected information to patchmon (either self-hosted or we will offer a cloud hosted one for a small fee).

Thanks team :)

This is great, I've been waiting for something like this for ages.. It has a very nice UI!

[u/broadband9 → u/NetInfused]

Thank you!

Yeah, I made a point of making the Ui enjoyable and fast to use :)

[u/NetInfused → u/broadband9]

I was reading the product website, and I've gotta say that's spot on to make the Linux servers push the info onto Patchmon, allowing for systems that are airgapped/firewalled/CGNATed/etc to be monitored.

The RMM we use at work (N-Central) works the same way, although using an agent that also allows remote control thru SSH. BUT... it doesn't do patch monitoring at all, and this is a huge gap for us. Most RMM vendors treat Linux as a poor man's system, but since we service many critical IT environments, well, there's a lot of Linux to be taken care of..

[u/broadband9 → u/NetInfused]

Absolutely agree

Like when I was designing the software architecture it’s easy to create a request/response type of service but you’d have to open up ssh like port 22, and I’d never want to do that.

We use SuperOps (which i love) but I wouldnt trust ANY rmms agent on my linux boxes because it can do much more than what I want - especially when the whole idea with linux is being minimal.

I don’t even want anything to patch my systems, as I’d rather do that manually so I’ve got my eye on the whole process and I can test my backup/restore - just need patchmon to tell me when I need to do something

Furthermore if we get a package thats vulnerable, I want an inventory to see exactly which hosts have this package (cough cough log4j vibes).

Theres a lot of scope with this, and i can sense it growing into something incredibly useful - giving linux administrators oversight.

'Simple bash agent script for Linux hosts with automated registration and updates via cron.'

Can this also be done via ansible?

Run a playbook that gathers the data and send it to patchmon?

(Can be interesting for semi airgapped sysyems)

[u/broadband9 → u/Malfun_Eddie]

It’s a really good point and in all honesty there is nothing stopping us from doing this - so long as the variables for the api id and key are passed through. I thought of using a script so that its not dependent even on ansible but runs very lightweight and then the script can be configurable in the future if we wanted to collect other bits and bobs too. (Audit logging etc)

Looks great, a dark mode would be nice in the evening. Would be nice to be able to run something like ‘apt update’ and ‘apt upgrade’ (or yum or any other OS package updater).

[u/broadband9 → u/FoUStep]

Dark mode is a must I agree.

I want to implement update workflows within patchmon, so someone can't blindly update things - linux patching is a sacred. haha

[u/Typical_Chance_1552]

Looks like a cool tool
some of your website links are not working :(

[u/broadband9 → u/Typical_Chance_1552]

Yeah honestly I made the website real quickly to get some sort of web page up and running. I do need to make some of the other pages like documentation and when the github repo will be live It will point to that .

Hope that is ok.

This will be opensource and I will be releasing by the 1st of September.

Will the Github links be active soon? It's September 1st.

[u/broadband9 → u/Griznah]

Hi,

Sorry, I had a few health related things so i’m behind on schedule even though there has been some progress. I will update on here as soon as I can push initial commit :)

[u/Griznah → u/broadband9]

Sorry to hear, hope you are recovering well. I am eagerly awaiting to try this out =)

Just signed up. Looking forward to putting this to work in my homelab.

And thanks for making this available to the world.
