I've copied a project that basically sends a message to telegram with informations when someone connects on a linux server.

But this time it's for MS Teams channels, which is possible through Webhooks.

I thought that might be interesting for other persons so I share :) It can probably be adapted to any other webhooks, as soon as webhook urls accepts the JSON sent.

This, but for Matrix network! Man, the possibilities with an alerting system like this!

If this means never having to open the Teams client ever again then I’m very excited.

20 years ago this capability was bog-standard for any team communication protocol. We've lost so many good workflows in the 21st century.

This is done via profile.d and can be circumvented by executing anything else than a login shell:

  ssh host /bin/sh -i

Better would be enabling PAM via sshd_config and generating the message from there.

We have logging and remote logging. If you don't check the logs isn't the fault of modernity.

Or to actually get a login shell, but without loading the profile:

> ssh host -t "bash --noprofile"

Cool idea, but I would have implemented this as a PAM-script rather than as a user profile script.
