SSH Login Notifications in Slack

It’s handy to know who’s logging into servers around your projects. Slack offers a beautiful way to do this in combination with pam.d.

I am assuming you’re using a CentOS-derived OS for locations, but this should work on any *nix-based OS with pam.d enabled.

1. Add an incoming webhook in Slack – navigate to: https://YOUR_DOMAIN.slack.com/apps/manage/custom-integrations We recommend naming the spot something that is recognizable; that way it won’t get deleted in the future.
